PHP form tutotial

An HTML form is a section of a document containing normal content, markup, special elements called controls (checkboxes, radio buttons, menus, etc.), and labels on those controls. Users generally "complete" a form by modifying its controls (entering text, selecting menu items, etc.), before submitting the form to an agent for processing (e.g., to a Web server, to a mail server, etc.)

Methods

The method attribute specifies how to send form-data (the form-data is sent to the page specified in the action attribute).

The form-data can be sent as URL variables (with method="get") or as HTTP post transaction (with method="post").

Notes on GET:

• Appends form-data into the URL in name/value pairs
• The length of a URL is limited (about 3000 characters)
• Never use GET to send sensitive data! (will be visible in the URL)
• Useful for form submissions where a user want to bookmark the result
• GET is better for non-secure data, like query strings in Google

Notes on POST:

• Appends form-data inside the body of the HTTP request (data is not shown is in URL)
• Has no size limitations
• Form submissions with POST cannot be bookmarked

How to Cancel PHP form submission using javascript

<?php 

$msg="";

if(isset($_POST['submit']))

{

$msg="ok";//put your code here

}

?>
