[wp-testers] Something odd happening with WP_Query()

[Gaarai]

I figured that there might be something obscure like that. I work on the 
back-end mostly, so I'm not aware of all the quirks of the front-end.

I traced all the function calls for calling the_tags(), and I believe 
that I found the problem. One of the functions in the call stack for 
the_tags() makes a call to in_the_loop(). The in_the_loop() function 
simply has the following code:

    function in_the_loop() {
        global $wp_query;

        return $wp_query->in_the_loop;
    }

I haven't tested this, but I believe if you manually set that var to 
true before you start your custom loop and then set it back afterwards, 
you can work past that limitation.

So unfortunately, it seems that you still have to do a hack job, but at 
least its not as problem laden as having to deal with PHP4/PHP5 
compatibility issues resulting from differences in how each handles 
object assignments.

To clarify my idea, you could do the following:

    global $wp_query;
    $wp_query->in_the_loop = true;

    /* custom loop code */

    $wp_query->in_the_loop = false;
      

I'm not saying that this is a good idea or that it will work, but it 
might help someone out there that doesn't want to deal with the mess. 
Having that code seems much more understandable to me than all the odd 
assignments to null, temp variables, etc.

If you try it out, let me know if it works. If it doesn't, there might 
be another reference to the $wp_query variable that I missed.
