====== Use a value from a posted form in PHP ======
When you post a form, the receiving page can process the form variables (in PHP) as follows:

<code php>$targetvar = $_POST['formvariablename'];</code>

It’s also a good idea to make sure you handle special HTML characters properly:

<code php>$targetvar = htmlspecialchars($_POST['formvariablename']);</code>

{{tag>php}}
