PHP Fastest way to get image width and height

Well, i am currently updating my WordPress plugin. I faced a problem in the past to retrieve image width to determine whether a particular image is require to resize. The problem here is that checking a particular image height and width is expensive job. In order to not impact the loading time of the site using my plugin, i forfeited the capability of resizing and resize the image regardless of the size. The plugin works fine since the resizing is doing it on the fly. However, problems arise when a smaller image is being resize and this is not a desirable result. Therefore, i would like to see whether there is a solution exist that can easily solve my problem.

Getting Image size using getImageSize()

Obviously, the task here is talking about PHP, we will look at the getImageSize() functionality exist within the naive php function. I personally was using this on the plugin to determine the size of the image. However, i immediately removed this after i notice the impact this functionality has caused on my site.

The reason? Remote image will need to be downloaded into your server and then it will be read locally by php. The pitfall here is the time used to download remotely to your server. If all your image is in your server and not somewhere else like in a CDN, this might not be a problem.

Better solutions

Well, the better solutions to get image quickly is to create your own script to retrieve the first few bytes of the file since the size of the image is located there. Credit goes to James @ zifiniti.com for the script below,

<?php
   function getimagesize($image_url){
    $handle = fopen ($image_url, "rb");
    $contents = ""; 
    if ($handle) {
    do {
        $count += 1;
        $data = fread($handle, 8192);
        if (strlen($data) == 0) {
            break;
       }   
    $contents .= $data;
    } while(true);
    } else { return false; }
    fclose ($handle);

    $im = ImageCreateFromString($contents);
    if (!$im) { return false; }
    $gis[0] = ImageSX($im);
    $gis[1] = ImageSY($im);
    // array member 3 is used below to keep with current getimagesize standards
    $gis[3] = "width={$gis[0]} height={$gis[1]}";
    ImageDestroy($im);
    return $gis;                                                                                                                                                       
   }   
}
?>

Assuming you have a large image file, this can really come in handle and reduce the time needed to load a site. But, its still slow! xD

List Of All Jobs in a select box

Today i was working on a registration and i needed a list of all job available for my user to choose. What will most of us do when this happen? Search Google! After that i left with despite because i fail to find such resource. The next terrifying thing most developer look at is the list of job available on Wikipedia (it just keep on going, damnit). Imagining compiling the whole few hundred list of job just to get them into a select box. Well, you don't have to imagine because i already did it. Hence, you get the joy while i do the work. lol~

Finally, this article has ended (after 200 tutorial i lost count). This really eats a lot of my time but i think it is worthwhile since i can refer back to it every single time and won't find myself in 'where's that tutorial again' situation. Nonetheless, if any of you are using this too, please throw in more photoshop photo effect tutorial that can benefit us all. Enjoy 🙂

17 JavaScript Form Validation Snippets

Last week i wrote 25 form validation for PHP. I find useful to have more layer of defend as JavaScript might malfunction or disable and cause your validation to fail but the form is still being passed on to our server. Nonetheless, JavaScript validation does provide certain level of restriction and protection for any web application. Especially when web is evolving quickly in this period of time. We are required to validate any data from our user to prevent any harm that can cause damage to our application and businesses. These JavaScript form validation snippets are needed in every form validation and repeating searching for them is unnecessary and slow down development processes. Therefore, you might want to bookmark these snippets for your future needs

Email Validation

Email validation is the most basic validation that any web application would have.

function isEmail(elem, helperMsg){
	var regexp  = /^([a-zA-Z0-9_\.\-])+\@(([a-zA-Z0-9\-])+\.)+([a-zA-Z0-9]{2,4})+$/;
	if(regexp.test(elem.value)){
		return true;
	}else{
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

In order to use this, we pass in an object and an alert value if it fail.

var email = document.getElementById('ham_email');
if(isEmail(email, "Invalid Email Format")){
//proceed..
}

URL Validation

URL validation helps to validate whether a particular string is a valid url format.

function isUrl(elem, helperMsg) {
	var regexp = /(ftp|http|https):\/\/(\w+:{0,1}\w*@)?(\S+)(:[0-9]+)?(\/|\/([\w#!:.?+=&%@!\-\/]))?/
	if(regexp.test(elem.value.toLowerCase())){
		return true;
	}else{
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

In order to use this, we pass in an object and an alert value if it fail.

var link = document.getElementById('ham_link');
if(isUrl(link, "Invalid link")){
//proceed..
}

Username Validation

This function help us validate whether a username contain valid character and length. It accept any underscore, alphabets and numbers within 5-25 characters.

function isValidUsername(elem, msg) {
	var regx = /^[A-Za-z0-9_]{5,25}$/;
	if(regx.test(elem.value)){
		return true;
	}else {
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

You can add additional symbols or change the length of the validation easily by alter the regular expression.

In order to use this, we pass in an object and an alert value if it fail.

var username = document.getElementById('username');
if(isValidUsername(username, "Invalid character found on username!")){
//proceed...
}

Password Validation

Here is a simple password strength validation that check the following criteria.

Passwords will contain at least 1 upper case letter
Passwords will contain at least 1 lower case letter
Passwords will contain at least 1 number or special character
Passwords will contain at least 8 characters in length
Password maximum length should not be arbitrarily limited

function isStrongPassword(elem, msg) {
	var regx = /(?=^.{8,}$)((?=.*\d)|(?=.*\W+))(?![.\n])(?=.*[A-Z])(?=.*[a-z]).*$/;
	if(regx.test(elem.value)){
		return true;
	}else {
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

In order to use this, we pass in an object and an alert value if it fail.

var password = document.getElementById('password');
if(isStrongPassword(password, "Your password fail the basic strength test. \n1. Passwords will contain at least 1 upper case letter\n2. Passwords will contain at least 1 lower case letter\n3. Passwords will contain at least 1 number or special character\n4. Passwords will contain at least 8 characters in length\n5. Password maximum length should not be arbitrarily limited\n")){
//proceed..
}

Numeric Validation

This validate whether a given string contain a valid numeric value which include both negative value and decimal ones.

function isNumeric(elem, helperMsg){
	var numericExpression = /^[-]?\d*\.?\d*$/;
	if(elem.value.toString().match(numericExpression)){
		return true;
	}else{
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

In order to use this, we pass in an object and an alert value if it fail.

var price = document.getElementById('price');
if(isNumeric(price, "Invalid value found")){
//proceed...
}

Text Empty Validation

In every form validation, there is always a need to check whether a particular text box is empty.

function isEmpty(elem, helperMsg){
	if(elem.value.toString().length > 0){
		return true;
	}else{
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

In order to use this, we pass in an object and an alert value if it fail.

var name = document.getElementById('ham_company');
if(!isEmpty(name, "Please give us your name")){
//proceed...
}

Radio Box Validation

We can determine whether a radio box has been selected using this function.

function hasSelected(elem, msg){
	for (i = 0; i < elem.length; i++) //for all check boxes
	{
		if (elem[i].checked == true ) //otherwise elements also looks at radio buttons
		{
			return true;
		}
	}
	alert(helperMsg);
	elem[0].focus();
	return false;
}

Drop Down Validation

We also check whether a particular drop down box has its value selected with the following function.
In order to use this, we pass in an object and an alert value if it fail.

var radio = document.getElementById('radio');
if(hasSelected(radio, Please select your gender")){
//proceed...
}

function isSelected(elem, helperMsg){
	if(elem.options[elem.selectedIndex].value.toString().length > 0){
		return true;
	}else{
		alert(helperMsg);
		elem.focus();
		return false;
	}
}

In order to use this, we pass in an object and an alert value if it fail.

var month = document.getElementById('ham_month');
if(isSelected(month, "Please select a month")){
//proceed...
}

Check Box Validation

We can perform check box validation to see whether a particular check box has been selected through this function.

function hasChecked(elem, msg){
	for (i = 0; i < elem.length; i++) //for all check boxes
	{
		if (elem[i].checked == true ) //otherwise elements also looks at radio buttons
		{
			return true;
		}
	}
	alert(helperMsg);
	elem[0].focus();
	return false;
}

In order to use this, we pass in an object and an alert value if it fail.

var checkbox= document. getElementsByName('checkbox');
if(checkPhone(checkbox, "Please tick one of the check box")){
//proceed...
}

Phone Validation

This function will validate the following criteria phone number.

phone:
339-4248
339-42-48
339 42 48
339 4248
3394248
(095) #phone#
(095)#phone#
+7 (095) #phone#
+7 (095)#phone#
+7(095) #phone#
+7(095)#phone#

function checkPhone(elem, msg)
{
	var str = elem.value;
	var phone2 = /^(\+\d)*\s*(\(\d{3}\)\s*)*\d{3}(-{0,1}|\s{0,1})\d{2}(-{0,1}|\s{0,1})\d{2}$/;
	if (str.match(phone2)) {
   		return true;
 	} else {
 		alert(helperMsg);
		elem.focus();
		return false;
 	}
}

In order to use this, we pass in an object and an alert value if it fail.

var phonenumber = document.getElementById('phonenumber');
if(checkPhone(phonenumber, "Invalid Phone Number")){
//proceed...
}

File Extension Validation

This function validate whether a particular upload string contains a valid extension.

function isAllowedFileExtension(elem, helperMsg){
	var alphaExp = /.*\.(gif)|(jpeg)|(jpg)|(png)$/;
	if(elem.value != "")
	{
		if(elem.value.toLowerCase().match(alphaExp)){
			return true;
		}else{
			alert(helperMsg);
			elem.focus();
			return false;
		}
	}
	else
		return true;
	return false;
}

In order to use this, we pass in an object and an alert value if it fail.

var upload = document.getElementById('ham_upload');
if(isAllowedFileExtension(upload, "Please Upload Gif, Png or Jpg Images Files Only")){
//proceed...
}

IP Validation

Sometimes there is a need to validate whether a particular IP address is valid using JavaScript.

function isValidIPAddress(elem, msg) {
   var re = /^\d{1,3}\.\d{1,3}\.\d{1,3}\.\d{1,3}$/;
   ipaddr = elem.value.toLowerCase();
   if (re.test(ipaddr)) {
      var parts = ipaddr.split(".");
      if (parseInt(parseFloat(parts[0])) == 0) { return false; }
      for (var i=0; i<parts.length; i++) {
         if (parseInt(parseFloat(parts[i])) > 255) { return false; }
      }
      return true;
   } else {
		alert(helperMsg);
		elem.focus();
		return false;
   }
}

In order to use this, we pass in an object and an alert value if it fail.

var ip= document.getElementById('ip');
if(isValidIPAddress(ip, "Invalid IP Address")){
//proceed...
}

US Social Security Number Validation

Testing US Social security number can be done with the below function.

function isValidSSN(elem, msg) {
	var value = elem.value.toLowerCase();
	var tmp = false;
    var re = /^([0-6]\d{2}|7[0-6]\d|77[0-2])([ \-]?)(\d{2})\2(\d{4})$/;
    if (!re.test(value)) { tmp = true; }
    var temp = value;
    if (value.indexOf("-") != -1) { temp = (value.split("-")).join(""); }
    if (value.indexOf(" ") != -1) { temp = (value.split(" ")).join(""); }
    if (temp.substring(0, 3) == "000") { tmp = true; }
    if (temp.substring(3, 5) == "00") { tmp = true; }
    if (temp.substring(5, 9) == "0000") { tmp = true; }

	if(tmp){
		alert(helperMsg);
		elem.focus();
		return false;
	}else
    return true;
}

In order to use this, we pass in an object and an alert value if it fail.

var ssn = document.getElementById('ssn');
if(isValidSSN(ssn, "Invalid US Social Security Number")){
//proceed...
}

US Zip Code Validation

We can valid US zip code using the following function.

function isValidZipCode(elem, msg) {
   var re = /^\d{5}([\-]\d{4})?$/;
   var value = elem.value.toLowerCase();
   if(re.test(value)){
		return true;
   }else {
		alert(helperMsg);
		elem.focus();
		return false;
   }
}

In order to use this, we pass in an object and an alert value if it fail.

var zip= document.getElementById('zip');
if(isValidSSN(zip, "Invalid US Zip Code")){
//proceed...
}

Date Validation

This function validate date with a given format.

function isValidDate(dateStr, format) {
   if (format == null) { format = "MDY"; }
   format = format.toUpperCase();
   if (format.length != 3) { format = "MDY"; }
   if ( (format.indexOf("M") == -1) || (format.indexOf("D") == -1) || _
      (format.indexOf("Y") == -1) ) { format = "MDY"; }
   if (format.substring(0, 1) == "Y") { // If the year is first
      var reg1 = /^\d{2}(\-|\/|\.)\d{1,2}\1\d{1,2}$/
      var reg2 = /^\d{4}(\-|\/|\.)\d{1,2}\1\d{1,2}$/
   } else if (format.substring(1, 2) == "Y") { // If the year is second
      var reg1 = /^\d{1,2}(\-|\/|\.)\d{2}\1\d{1,2}$/
      var reg2 = /^\d{1,2}(\-|\/|\.)\d{4}\1\d{1,2}$/
   } else { // The year must be third
      var reg1 = /^\d{1,2}(\-|\/|\.)\d{1,2}\1\d{2}$/
      var reg2 = /^\d{1,2}(\-|\/|\.)\d{1,2}\1\d{4}$/
   }
   // If it doesn't conform to the right format (with either a 2 digit year or 4 digit year), fail
   if ( (reg1.test(dateStr) == false) && (reg2.test(dateStr) == false) ) { return false; }
   var parts = dateStr.split(RegExp.$1); // Split into 3 parts based on what the divider was
   // Check to see if the 3 parts end up making a valid date
   if (format.substring(0, 1) == "M") { var mm = parts[0]; } else _
      if (format.substring(1, 2) == "M") { var mm = parts[1]; } else { var mm = parts[2]; }
   if (format.substring(0, 1) == "D") { var dd = parts[0]; } else _
      if (format.substring(1, 2) == "D") { var dd = parts[1]; } else { var dd = parts[2]; }
   if (format.substring(0, 1) == "Y") { var yy = parts[0]; } else _
      if (format.substring(1, 2) == "Y") { var yy = parts[1]; } else { var yy = parts[2]; }
   if (parseFloat(yy) <= 50) { yy = (parseFloat(yy) + 2000).toString(); }
   if (parseFloat(yy) <= 99) { yy = (parseFloat(yy) + 1900).toString(); }
   var dt = new Date(parseFloat(yy), parseFloat(mm)-1, parseFloat(dd), 0, 0, 0, 0);
   if (parseFloat(dd) != dt.getDate()) { return false; }
   if (parseFloat(mm)-1 != dt.getMonth()) { return false; }
   return true;
}

You will use the function this way,

if (!isValidDate(myDateString, "DMY")) { alert("The date is not in the correct format."); }

Time Validation

This function validate time such as

02:25AM
00:23PM
23:45PM
11:23
etc.

function isValidTime(value) {
   var hasMeridian = false;
   var re = /^\d{1,2}[:]\d{2}([:]\d{2})?( [aApP][mM]?)?$/;
   if (!re.test(value)) { return false; }
   if (value.toLowerCase().indexOf("p") != -1) { hasMeridian = true; }
   if (value.toLowerCase().indexOf("a") != -1) { hasMeridian = true; }
   var values = value.split(":");
   if ( (parseFloat(values[0]) < 0) || (parseFloat(values[0]) > 23) ) { return false; }
   if (hasMeridian) {
      if ( (parseFloat(values[0]) < 1) || (parseFloat(values[0]) > 12) ) { return false; }
   }
   if ( (parseFloat(values[1]) < 0) || (parseFloat(values[1]) > 59) ) { return false; }
   if (values.length > 2) {
      if ( (parseFloat(values[2]) < 0) || (parseFloat(values[2]) > 59) ) { return false; }
   }
   return true;
}

Credit Card Validation

This function validate whether a given string format is similar to a credit card type.

function isValidCreditCard(type, ccnum) {
   if (type == "Visa") {
      // Visa: length 16, prefix 4, dashes optional.
      var re = /^4\d{3}-?\d{4}-?\d{4}-?\d{4}$/;
   } else if (type == "MC") {
      // Mastercard: length 16, prefix 51-55, dashes optional.
      var re = /^5[1-5]\d{2}-?\d{4}-?\d{4}-?\d{4}$/;
   } else if (type == "Disc") {
      // Discover: length 16, prefix 6011, dashes optional.
      var re = /^6011-?\d{4}-?\d{4}-?\d{4}$/;
   } else if (type == "AmEx") {
      // American Express: length 15, prefix 34 or 37.
      var re = /^3[4,7]\d{13}$/;
   } else if (type == "Diners") {
      // Diners: length 14, prefix 30, 36, or 38.
      var re = /^3[0,6,8]\d{12}$/;
   }
   if (!re.test(ccnum)) return false;
   // Remove all dashes for the checksum checks to eliminate negative numbers
   ccnum = ccnum.split("-").join("");
   // Checksum ("Mod 10")
   // Add even digits in even length strings or odd digits in odd length strings.
   var checksum = 0;
   for (var i=(2-(ccnum.length % 2)); i<=ccnum.length; i+=2) {
      checksum += parseInt(ccnum.charAt(i-1));
   }
   // Analyze odd digits in even length strings or even digits in odd length strings.
   for (var i=(ccnum.length % 2) + 1; i<ccnum.length; i+=2) {
      var digit = parseInt(ccnum.charAt(i-1)) * 2;
      if (digit < 10) { checksum += digit; } else { checksum += (digit-9); }
   }
   if ((checksum % 10) == 0) return true; else return false;
}

Summary

Usually i will use these code in such a way to validate my form. I find it neat and tidy.

form.onsubmit = validation;
var validation = function(){
	var name = document.getElementById('ham_company');
	var email = document.getElementById('ham_email');
	var link = document.getElementById('ham_link');
	var description = document.getElementById('ham_desc');
	var banner = document.getElementById('ham_banner');
	var month = document.getElementById('ham_month');
	var url = document.getElementById('ham_url');
	var upload = document.getElementById('ham_upload');
	var quiz = document.getElementById('ham_quiz');
	if(isEmail(email, "Invalid Email Format"))
		if(isUrl(link, "Invalid link"))
			if(OneNotEmpty(url, upload, "Either image url or upload must be perform!"))
				if(isAllowedFileExtension(url, "Please provide an image with Gif, Png or Jpg extension Only"))
					if(isAllowedFileExtension(upload, "Please Upload Gif, Png or Jpg Images Files Only"))
						if(isSelected(month, "Please select a month"))
							if(isSelected(banner, "Please select a banner"))
								if(NotEmpty(quiz, "Please answer the quiz"))
									if(NotEmpty(name, "Please give us your name"))
									{
										return true;
									}

	return false;
}

On the other hand, you can always brings up new form validation snippets to share with me in this article. I will love to know 🙂

Inline, Internal or External CSS Style Print First?

It is a common thing for most web beginners to wonder which style will the browser print first when we declare multiple style. Although i have explain previous on the order priority of CSS, i forgotten about the importance of inline, internal and external CSS style that both designers and developers might wonder when they started on web.

Inline CSS

The inline CSS also refer as embedded style is usually mark as the highest priority over internal or external style. An inline style has the highest priority among others but the style can only be apply to an individual element. Here's an example

<div style='height:200px;width:200px;text-align:center;'>Click me!</div>

Inline style may be convenient to write but maintenance work will definitely kill you one day.

External CSS

The external CSS which the style is usually placed on an external file will usually have the lowest priority over these three type.

<link rel="stylesheet" type="text/css" href="http:/hungred.com/external.css">

Nonetheless, sometimes external CSS can have higher priority over the internal CSS in some circumstances.

Internal CSS

Internal CSS are definition declare inside of the HTML document with the style tag,

<style type='text/css'>
div{
height:200px;
width:200px;
text-align:center;
}
</style>

Internal CSS usually have the second highest priority among them. However, it will lose its priority if the external stylesheet declaration is placed at after the internal CSS. Hence,

<link rel="stylesheet" type="text/css" href="http:/hungred.com/external.css">
<style type='text/css'>
div{
height:200px;
width:200px;
text-align:center;
}
</style>

the internal CSS is after the external CSS. Therefore, the internal CSS has a higher priority. On the other hand,

<style type='text/css'>
div{
height:200px;
width:200px;
text-align:center;
}
</style>
<link rel="stylesheet" type="text/css" href="http:/hungred.com/external.css">

when the external CSS is after the internal CSS, the external CSS will have a higher priority.

Priority Sequences

Hence, we can produce a priority sequences of how CSS prioritize our CSS types.

User Style
Inline Style (inside HTML tag)
Internal Style (usually on the HTML head section)
External Style
Browser Default Style

User style (the style that user define for your website) have the highest priority over all other types but as a developer or designer we should only worry about the priority given on inline, internal and external style. Nonetheless, it is also important to know that using !important will also mean that user style priority is overwrite by the HIGHEST priority (which is style declare with !important). That is also the reason why we should try to avoid the use of !important as a developer or designer to avoid any usability problem and utilize order priority in CSS.

Summary

Once we understand how order priority work in CSS, we can easily figure out how CSS cascade all our different styles into one. But one last thing to take note of. The order priority in this link only apply to internal and external style. Hence, if both internal and external have the same exact style definition which order priority in this link will CSS take as the highest priority. The answer lays in this article where we explain on the internal CSS section.
