Hello Guys,

I need some help here..

I have a page that has a grid on it and I have a hidden div(below the grid). When the link is clicked inside the grid it opens the hidden div using the following code for the link in the grid.

Here is my code with the PHP id that I need to pass


foreach($ct->data as $key => $value){
$ct->data[$key][3]='<a href=#" onclick="part2('.$ct->data[$key][0].');" href="javascript:void();">'.$ct->data[$key][3].'</a>';

Here is the code in my head

<script type="text/javascript">
function part2(id) {
var part2 = document.getElementById('part2');
if ( part2.className == 'hidden' ) {
part2.className = 'visible';
document.getElementById('message').InnerHTML = 'This is the ID: '+id
} else {
part2.className = 'hidden';
}
}
</script>

Added this to my hidden div to show the id

<span id=message></span>


Any help would be appreciated..

Thanks, Dan

It's innerHTML and not InnerHTML ... Javascript is case sensitive

Hey that done it.. Thanks so much for you help..

One more question.. How can I grab that id and add it back as a php id?

in the layer?

currently it displays because of this - <span id=message></span>

I want it to be passed to PHP

Like this

$id

Any ideas?

I don't get that ... what should be the result of such an action? You need to understand that PHP already finished(!) running when javascript runs. So you can not pass variables to PHP just like that.

The only thing you could do is start a new request to a PHP, either through browser redirect or an Ajax call.
