The fetch_template how do I test to see if the templete exist in PHP
 

In the following PHP code

I want to test the what the templatecache or the database
or both how do it in PHP of the line below.

$dummy = fetch_template('groups_index_listbit'); // returns a string
echo $dummy;

What is actualy being returned here ?
string fetch_template (string $templatename);
where
string $templatename: Name of template to be fetched

So How do I debug this and echo the values correctly above here.

Note: This works fine here and I can echo the values in the actaul array.

echo $groupslist[id];
echo "<br>";
echo $groupslist[groupname];
echo "<br>";

eval('$groupslist .= "' . fetch_template('groups_index_listbit') . '";');

Why does the line above need the . dot operator is it becuse it is a string type being returned ?

How does the eval work in the above case in vbullutin please explain. THANKS

The groups_index_listbit template is a template that will be looped several times. When you add the concatenating assignment operator ('.='), this will allow you to call this template over and over again untill the MySQL query runs out of data.

For example: If you wanted to echo every username in your database, you would create a mysql query telling the database to give you all usersname is the user row. And echo everyname. Heres how we would do this.

The $query variable holds the mysql commands.
This next code is creating an array. Each and every row of the usertable will be instered into the $user variable. The while() function will loop this array. Read the highlited comments in the code below...
Hope this helps. It's late and explaing something is hard right now. I've had a couple of drinks. :p
