Most forms use the post method because it “hides” the form data away from the user and doesn’t clutter up the URL in the address bar. Note that GET and POST methods are equally (in)secure. As easily as a user can monkey with GET data in a URL, the same thing can be done with POST data.You should always assume that the user can submit whatever form and form data that they want to, and process the data accordingly. Don’t trust user input, whether it’s from GET or from POST!sing “isset”. You can use the “isset” function on any variable to determine if it has been set or not. You can use this function on the $_POST array to determine if the variable was posted or not. When a web form is submitted to a server through an HTTP POST request, a web user that attempts to refresh the server response in certain user agents can cause the contents of the original HTTP POST request to be resubmitted, possibly causing undesired results, such as a duplicate web purchase.ost/Redirect/Get (PRG) is a web development design pattern that prevents some duplicate form submissions, creating a more intuitive interface for user agents (users). Example. When the user fills out the form above and clicks the submit button, the form data is sent for processing to a PHP file named welcome.php. The form data is sent with the HTTP POST method.To display the submitted data you could simply echo all the variables.ET vs. POST. Both GET and POST are treated as $_GET and $_POST. These are superglobals, which means that they are always accessible, regardless of scope-and you can access them from any function, class or file without having to do anything special. Introduction to the form. POST data is submitted by a form and “posted” to the web server as form data. POST data is encoded the same way as GET data, but isn’t typically visible to the user in standard browsers.sing “isset”.

POST Method Example Using Form: Let us do little modification in the above JSP to handle GET as well as POST methods.

According to the HTTP specification, you should use the POST method when you're using the form to change the state of something on the server end. For example, if a page has a form to allow users to add their own comments, like this page here, the form should use POST.he basic concept that is important to understand is that any form element will automatically be available to your PHP scripts. Please read the manual section on Variables from external sources for more information and examples on using forms with PHP. Here is an example HTML form: Example #1 A simple HTML form. name-it's usually a good idea to give your forms a name, this is used to uniquely identify your form on a given page. method-the value of this should be POST or GET. This tells the form how to send the data once submitted.ame-it's usually a good idea to give your forms a name, this is used to uniquely identify your form on a given page. method-the value of this should be POST or GET. This tells the form how to send the data once submitted. Consider the first scenario where the form’s method attribute is set to GET. form .. method=”GET” .. action=”/somepage.php”. When the user submits the data, the name-value pairs of the form elements are url-encoded and transmitted in the URL as..he client can see this string in the Addressbar. If you want to “hide” this data, you can set the method to POST, By setting it to POST, the browser sends the data in the request header’s body. So if the method is POST of the same form above, the request header would be as …. POST /somepage.php HTTP/1.1.
You can use the “isset” function on any variable to determine if it has been set or not. You can use this function on the $_POST array to determine if the variable was posted or not.
