button + php

[Cheerion]

hello,

does anyone know how to call a php function from a button?? So what has to be in the onClick='' section?

the php function is called : verwijderen()

so this is what i have:

<input type=button value=Delete onClick=' ????? '>

thx in advance

Try the following:

Click.html

<form action="click.php" method="post">
<input type="submit" value="Click me">
</form>

click.php

<?php

verwijderen();

?>

my problem isn't solved :-(

I want to click a button an then a javascript window asks are you sure you want to delete this game. And when the say "yes" the game has to be deleted! And when the say "no" it stays there:

This is what i'm trying right now but it isn't working:

PHP:
printf("<input type=button name=verwijderen value=Verwijderen onClick='test = verwijderen(%s);'>",$myrow["id"];

JAVASCRIPT FUNCTION :

function verwijderen(id){
alert("test");
<?
$SQL = "update fsb_wedstrijden set confirm = 0 where id = '$id'";
mysql_query( $SQL ) or die( mysql_error() );
?>
return 1;
}

oh wait, you cannot execute PHP within javascript. try this:

verwijderen.php

<?
if (isset($_POST['action']) && $_POST['action'] == "verwijderen") {
    if (isset($_POST['id']) && !empty($_POST['id']) {
        $SQL = "update fsb_wedstrijden set confirm = 0 where id = '$id'"; 
        mysql_query( $SQL ) or die( mysql_error() );
    }
}
?>
<script type="text/javascript" language="JavaScript1.2">
function confirmSubmit()
{
var agree=confirm("Weet u zeker dat u dit verslag wilt bijwerken?");
if (agree)
	return true ;
else
	return false ;
}
</script>
<form method="post" action="<?$PHP_SELF?>">
<input type="hidden" name="action" value="verwijderen">
ID: <input type="text" name="id">
<input type="submit" name="verwijderen" value="Verwijderen" onClick="return confirmSubmit();">
</form>
