Posting to Self

I have a page displaying data from a mySQL db which I want to filter. So I figured I could have a button and a couple of fields at the top of my page:

Date
Category

I want to click submit, have the results filtered but on the same page. How do I do that?

<form action="<?php echo $_SERVER['PHP_SELF'] ?>" method="POST">

First of all, create a PHP file with this :

phpinfo();

Then in the "PHP Variables" section, try to find the variable that could give you the current path to your file...

Now, in your form, add a name to the submit button... let's say... submit (how original !) (name="submit")...

In your script, if submit is set, that means the form has been sent, so check if submit is set. If it is set, verify the form, otherwise, if not set, simply show the form...

Now, you need to convert my words to PHP code. Good luck 🙂

Do I need to build a query string for the WHERE clause? How do I cope if the fields are empty?

<?php
// it is safer to "filter" the PHP-Self variable to help reduce XSS attacks:
$safe_self = htmlentities($_SERVER['PHP_SELF'], ENT_QUOTES, 'UTF-8');
?>
<form action="<?php echo $safe_self; ?>" method="POST">
