Passing Variables from Template to Class?
4 March 2010 at 4:28am
I'm iterating in my template through a DataObjectSet coming from a custom DB::query(). I need to start a new html list every 25 items. The trouble is, I don't know how to pass the loop position ($Pos) back to the PHP class to do the modulo calculation. The trouble is, I don't know where to put my code.
Template:
<% control GetPastClients %>
<% if BeginNewList(25) %>
<div style="float:left;">
<ul>
<% end_if %>
<li>
<h6>$ClientName</h6>
</li>
<% if EndList %>
</ul>
</div>
<% end_if %>
<% end_control %>PHP:
function BeginNewList($ItemsPerList) {
if(($this->Pos()-1) % $ItemsPerList == 0) {
echo("HELLO!");
return true;
} else {
return false;
}
}There are 159 items in the DataObjectSet. Can anyone tell me why this function prints out nothing? It's as if it doesn't exist. What I erally need to do here is to pass the Pos() from the template [<% if BeginNewList(Pos) %>] but I I can't seem to do this for some reason. Anyoen have any idea how I can accomplish what I'm trying to do here?
Thanks,
