Html action php self

LearningSpot

PHP_SELF is a variable that returns the current script being executed. This variable returns the name and path of the current file (from the root folder). You can use this variable in the action field of the FORM. There are also certain exploits that you need to be aware of. We shall discuss all these points in this article.

echo $_SERVER[‘PHP_SELF’];
a) Suppose your php file is located at the address:
http://www.yourserver.com/form-action.php
In this case, PHP_SELF will contain:
«/form-action.php»
b) Suppose your php file is located at the address:
http://www.yourserver.com/dir1/form-action.php
For this URL, PHP_SELF will be :
«/dir1/form-action.php»

A common use of PHP_SELF variable is in the action field of the

tag. The action field of the FORM instructs where to submit the form data when the user presses the “submit” button. It is common to have the same PHP page as the handler for the form as well.
