Queued Photo Uploader with J query

Java Script Code For that Tool

Html Code :

<form action="../script.php" method="post" enctype="multipart/form-data" id="form-demo">
 
 <fieldset id="demo-fallback">
  <legend>File Upload</legend>
  <p>
   This form is just an example fallback for the unobtrusive behaviour of FancyUpload.
   If this part is not changed, something must be wrong with your code.
  </p>
  <label for="demo-photoupload">
   Upload a Photo:
   <input type="file" name="Filedata" />
  </label>
 </fieldset>
 
 <div id="demo-status" class="hide">
  <p>
   <a href="#" id="demo-browse">Browse Files</a> |
   <a href="#" id="demo-clear">Clear List</a> |
   <a href="#" id="demo-upload">Start Upload</a>
  </p>
  <div>
   <strong class="overall-title"></strong><br />

PHP - Necessary Setup

PHP - Necessary Setup

• A web hosting account that supports the use of PHP web pages and grants you access to MySQL databases. If you do not have a host, but are interested in signing up for one, we recommend that you first read our Web Host Guide to educate yourself about web hosting and avoid getting ripped off.
• Have PHP and MySQL installed on your own computer. Read this lesson thorougly for more information on installing PHP.

Although MySQL is not absolutely necessary to use PHP, MySQL and PHP are wonderful complements to one another and some topics covered in this tutorial will require that you have MySQL access.

Installing PHP

For those who are experienced enough to do this yourself, simply head over to PHP.net - Downloads and download the most recent version of PHP.
However, if you are like most of us, you will most likely want to follow a guide to installing PHP onto your computer. These guides are kindly provided by PHP.net based on the operating system that you are using.

• PHP - Windows - Windows Installation Guide
• PHP - Mac - Mac Installation Guide
• PHP - Linux - Linux Installation Guide

Installing MySQL

Visit MySQL's MySQL Installation Guide for help on installing MySQL. 

 

Example using control structures and functions

<?phpif (strpos($_SERVER['HTTP_USER_AGENT'], 'MSIE') !== FALSE) {
    echo 'You are using Internet Explorer.<br />';
}?>

 

Here we introduce a couple of new concepts. We have an if statement. If you are familiar with the basic syntax used by the C language, this should look logical to you. Otherwise, you should probably pick up an introductory PHP book and read the first couple of chapters, or read the Language Reference part of the manual.

The second concept we introduced was the strpos() function call. strpos() is a function built into PHP which searches a string for another string. In this case we are looking for 'MSIE' (so-called needle) inside $_SERVER['HTTP_USER_AGENT'] (so-called haystack). If the needle is found inside the haystack, the function returns the position of the needle relative to the start of the haystack. Otherwise, it returns FALSE. If it does not return FALSE, the if expression evaluates to TRUE and the code within its {braces} is executed. Otherwise, the code is not run. Feel free to create similar examples, with if, else, and other functions such as strtoupper() and strlen(). Each related manual page contains examples too. If you are unsure how to use functions, you will want to read both the manual page on how to read a function definition and the section about PHP functions.

 

Printing a variable (Array element)

<?phpecho $_SERVER['HTTP_USER_AGENT'];?>

 

There are many types of variables available in PHP. In the above example we printed an Array element. Arrays can be very useful.

$_SERVER is just one variable that PHP automatically makes available to you. A list can be seen in the Reserved Variables section of the manual or you can get a complete list of them by looking at the output of the phpinfo() function used in the example in the previous section.

 

Example of PHP "Hello word"

Our first PHP script: hello.php

<html>
 <head>
  <title>PHP Test</title>
 </head>
 <body>
 <?php echo '<p>Hello World</p>'; ?>
 </body>
</html>

When developing locally this URL will be something like http://localhost/hello.php

<html>
 <head>
  <title>PHP Test</title>
 </head>
 <body>
 <p>Hello World</p>
 </body>
</html>

  

PHP requirement

Let us say you want to save precious bandwidth and develop locally for php. In this case, you will want to install a web server, such as » Apache, and of course » PHP. You will most likely want to install a database as well, such as » MySQL.
