Site Members Loop & Variables

I’m working on a plugin that utilizes “The Site Members Loop“

The first line of the loop says

<?php if ( bp_has_site_members( 'type=active&max=5' ) ) : ?>

What I would like to do is put a variable where the max number is. I can put a variable where active is and it works fine. But if I put a variable where the max number is

(i.e. &max=$come_on_you_dang_thing) it kicks out the following error:

Warning: Division by zero in C:… buddypressbp-corebp-core-templatetags.php on line 819

The area around line 819 (so you dont have to go look) says
```
$this->pag_links = paginate_links( array(

'base' => add_query_arg( 'upage', '%#%' ),

'format' => '',

'total' => ceil( (int) $this->total_member_count / (int) $this->pag_num ),

'current' => (int) $this->pag_page,

'prev_text' => '&laquo;',

'next_text' => '&raquo;',

'mid_size' => 1

));
```
The longest line there is 819.

So…??? Any clue why it’s kicking out that division error and how I can fix it??

Thanks in advance for your help!!

Just putting a $var in the template doesn’t mean that the $var is available in that scope. Unless you are generating the value of $var in the template itself it will resolve to 0 and be passed along to bp.

If he’s trying to do…

<?php if ( bp_has_site_members( 'type=' . $foo1 . '&max=' . $foo2 ) ) : ?>

…then in theory it *should* work, at least from what I see.

I’ll have time in the morning to check on this if you don’t by then Burt.

I’ve run into this before. That code snippet above only works if the $foo’s are created in the template. The code underneath that contains $foo’s is a different scope.

Thanks JJJ & Burt for your responses.

Burt, you said “Unless you are generating the value of $var in the template itself….” Basically, what I was doing, and sorry I didn’t include this in my code, was
```
<?php

$var = 5;

if ( bp_has_site_members( 'type=active&max=$var' ) ) : ?>
```
I was doing it the most simple way I could think of just to see if it would work first but that number as a variable was killing me.

Should I look at $foo’s or is that not the right solution? Thanks again.

How about this:
```
<?php

$var = 5;

if ( bp_has_site_members( 'type=active&max=' . $var ) ) : ?>
```

@burtadsit I have been able to achieve a positive result using @jeffsayre ‘s code, however I want to set the value of my $var outside the template. Do you know if this is possible? I fear not based on what you said above:

“I’ve run into this before. That code snippet above only works if the $foo’s are created in the template. The code underneath that contains $foo’s is a different scope.”

I’ve tried setting my $var in my functions.php file and in my custom page template by hooking in to bp_before_members_loop:

<?php
function my_function() {
$var = ‘xxx’;
}
add_action(‘bp_before_members_loop’,’my_function’);
?>

Many thanks!

@dunc – If you want a global variable, then (surprise, surprise!) use a global variable or a define.

In wp-config.php or /wp-content/plugins/bp-custom.php, you can either do this:

global $my_var;
$my_var = WHATEVER;

or:

define( 'MY_VAR', WHATEVER );

Then in your page template or anywhere else, you do this:

global $my_var;
if ( bp_has_site_members( 'type=active&max=' . $my_var ) ) :

or:

if ( bp_has_site_members( 'type=active&max=' . MY_VAR ) ) :

—

Hope that helps.
