Question

I have a search field with name attribute q, and after a click on the submit button I want the form to go to the same page, (which is index.php) so I set the action of the form like this :

'index.php?a=nl&b=search'.

I want that the url that is navigated to is like this (so the action-url + the name of the field):

'index.php?a=nl&b=search&q=search-term'. 

However after a click the page navigates just to

'index.php?q=search-term'

Is there a way to fix this ?

Answer 1

Make the form method as GET and add fields as hidden fields.

looks like your form has only q input field (and a submit button without name attrib). Add the ones you want to append to the url after submit as hidden inputs – ex:

<form method="get" action="yoururl.com?a=nl&b=search">
<input type="hidden" name="a" value="<?php echo isset($_GET['a']) ? $_GET['a'] : ''; ?>"/>
<input type="hidden" name="b" value="<?php echo isset($_GET['b']) ? $_GET['b'] : ''; ?>"/>

….. rest of the form …
