Php $_post

[welcomewiki]

The $_POST variable is used to collect values from a form with method="post".


The $_POST Variable

The $_POST variable is an array of variable names and values sent by the HTTP POST method.


The $_POST variable is used to collect values from a form with method="post". Information sent from a form with the POST method is invisible to others and has no limits on the amount of information to send.

Example

Enter your name:
Enter your age:

When the user clicks the "Submit" ****on, the URL will not contain any form data, and will look something like this:


https://wikinewforum.com



The "welcome.php" file can now use the $_POST variable to catch the form data (notice that the names of the form fields will automatically be the ID keys in the $_POST array):
Welcome .

You are years old!

Why use $_POST?

• Variables sent with HTTP POST are not shown in the URL
• Variables have no length limit

However, because the variables are not displayed in the URL, it is not possible to bookmark the page.





The $_REQUEST Variable

The PHP $_REQUEST variable contains the contents of both $_GET, $_POST, and $_COOKIE.


The PHP $_REQUEST variable can be used to get the result from form data sent with both the GET and POST methods.



Example

Welcome .

You are years old!
