php button parameter gets lost

Question

I am creating a button in php and want to call a php with parameter when clicked:

echo '<form method="get" action="./ash.php?q=Y"    >';
echo '<button type="submit"    >QUERY</button>';
echo '</form>';

When I click on the button, ash.php gets indeed called, but the q parameter has been 'forgotten' in the process. How can that be?

Why don't you put a hidden field with the name q and the value of Y — iamsleepy

That's actually a feature, not a bug, you're not supposed to form an action attribute that way. — Laurent S.

so, test your parameters into ash.php : $q = (isset($_GET['q')) ?: ''; — ceadreak

echo '<form method="get" action="./ash.php"    >';
echo '<input type="hidden" name="q" value="Y" />';
echo '<button type="submit"    >QUERY</button>';
echo '</form>';
