HTML Form Handling in PHP
Review
You’re ready to start handling forms in PHP!
To review:
<?=is shorthand for<?php echo.- PHP provides superglobals which can be accessed anywhere in the script.
$_GETis an associative array containing data from a GET request.$_POSTis an associative array containing data from a POST request.$_REQUESTis an associative array containing data from both GET and POST requests. It should only be used if you don’t care which method was used.
- The array keys in the PHP request superglobals are set by the
nameattributes in the HTML form, which need to be unique. - The
actionattribute is used to specify which file should handle data from the form request.
Instructions
This code contains two forms:
- A form using the GET method, which is submitted and handled by handle_get.php.
- A form using the POST method, which is submitted back to the same file (no
actionattribute).
Use these forms to check your understanding of how PHP handles the form inputs.
