PHP variable in FORM action

[steveh]

In the following code snippet, what I want to happen is the action attribute to be set depending on the item selected.

What is actually happening is that when the form is "created", $fp hasn't been set yet.

Can anybody help me out on this one ?

Regards
Steve

<?php
print ('<form method="GET" action=' . $fp . '.html' . '>');
?>
<select size="1" name="fp">
<option value=0>July<br>
<option value=1>August<br>
<option value=2>September<br>
<option value=3>October<br>
<option value=4>November<br>
<option value=5>December<br>
<option value=6>January<br>
<option value=7>February<br>
<option value=8>March<br>
<option value=9>April<br>
<option value=10>May<br>
<option value=11>June<br>
</select>
<input type="submit" value="Submit" name="submit">
</form>

First off...you don't set the action to an HTML page...you set the action to a script like a .pl or .php script.

I'm assuming that the users form submission will be the deciding factor as to the HTML page that you want to display.

Based on this, you'd have the script evaluate the user selection and redirect the user to that page.

That's the way I'd do it.

or even set the action to a php script that includes the proper html page.

You know it looks like what you're thinking of is a javascript dropdown navigation. You know, where onChange you would grab document.formname.element.selectedvalue and set the browser location to what was chosen.

I can't remember the JS syntax at the moment, it's too early :p but just as a personal choice I don't prefer the method. I'd recommend generating navigation values before the form is displayed and just use a submit button.

Use JavaScript instead.

<script language="text/javascript">
function changeAction() {
document.frmMonths.action=document.frmMonths.fp.value+'.php';
}
//give your form a default action
document.frmMonths.action='0.php';
</script>

<form name="frmMonths" method="GET" action="">
<select size="1" name="fp" onchange="changeAction();">
<option value=0>July<br>
<option value=1>August<br>
<option value=2>September<br>
<option value=3>October<br>
<option value=4>November<br>
<option value=5>December<br>
<option value=6>January<br>
<option value=7>February<br>
<option value=8>March<br>
<option value=9>April<br>
<option value=10>May<br>
<option value=11>June<br>
</select>
<input type="submit" value="Submit" name="submit">
</form>

This isn't perfect, but you need a client-side script to do what you want.

You could also code a php script to grab the value from the select box and output code dependant on that.
