Calling a php function after hitting a form submit

Fatboy

In a file called form.php I have:

<form name="vote" action="addvote($votevalue)" method="post">

<select name=votevalue>
<option label="0" value="0">0</option>
<option label="1" value="1">1</option>
<option label="2" value="2">2</option>
<option label="3" value="3">3</option>
<option label="4" value="4">4</option>
<option label="5" value="5" selected="selected">5</option>
<option label="6" value="6">6</option>

<option label="7" value="7">7</option>
<option label="8" value="8">8</option>
<option label="9" value="9">9</option>
<option label="10" value="10">10</option>

</select>
<input name="submit" type="submit" value="Vote Now!">
</form>

in a file called functions.php I have a function called addvote() that needs the value $votevalue passed to it from the form.

My question is - how do I call that function from the form ????

Cheers

set your action as the file...

functions.php?action=addvote

then in functions.php

//only call addvote() if action is correct and votevalue was submitted also
if (isset($_POST['action']) && $_POST['action'] == 'addvote' && isset($_POST['votevalue']))
{
  addvote($_POST['votevalue']);
}

hehe, gotta love the mililtary... they get all the holidays "remembering them" blah blah, but most of them all have to work those days... talk about irony :rolleyes:

Fatboy

Well, had to change a couple of $POST to $GET and it worked fine :s

if (isset($_GET['action']) && $_GET['action'] == 'addvote' && isset($_POST['votevalue']))

working fine now 🙂

Cheers - enjoy the rest of your day at work!

If the PHP function is in the same script, how do I call it in "action" in a form? My code does not work. Thanks.

<?php

Function vote () {
echo "inside function vote";
echo "<br />";

if(isset($_POST['submitb'])) {
	echo "inside if";
	echo "<br />";
}

static $testvar = 0;
	echo "assigned testvar as static, should be done once only -->";
	echo $testvar;
	echo "<br />";
$testvar++;
	echo "increament of testvar, should be done everytime -->";
	echo $testvar;
	echo "<br />";

}
?>

<form method="post" action="<?php echo(htmlentities($_SERVER['PHP_SELF'])); ?>?vote" >
		<input type="image" width=5% src="pix/camera.gif" name="submitb" value="submit" >
</form>

</body>
</html>
