Hi Experts,

Can you please help me understand why line8 isn't working?

What I'm trying to achieve is something similar to $this->countModules() in a non-index.php file.

Thanks
Rick

function topSpanSize(){

    
    // count modules in the top container

    $modCount=0;
    for($i=1; $i<=3; $i++){
        $module=JFactory::getDocument()->countModules('top-'.$i);
        if(!$module==0){  
            $modCount++;
        }
    }
     

    /* Calculate the span size based
     * on module count. e.g. If only 1 
     * module exist in the top-container 
     * then it should take up the whole row. 
     * i.e. span12  */

    if ($modCount<>0){
       $topSpanNum = 12/$modCount; 
    }
    else{
       $topSpanNum = 0;
    }
    
    return $topSpanNum;
}

What is happening when you try that code?  Have you tried dumping any of the variables to see what is being returned?

function topSpanSize(){
    // count modules in the top container
    $modCount=0;
    for($i=1; $i<=3; $i++){
        $x=JFactory::getDocument();     // <------------- what happens here?
        die(print_r($x,1));             // <------------- what happens here?
        $module=JFactory::getDocument()->countModules('top-'.$i);
        if(!$module==0){  
            $modCount++;
        }
    }
    /* Calculate the span size based
     * on module count. e.g. If only 1 
     * module exist in the top-container 
     * then it should take up the whole row. 
     * i.e. span12  */
    if ($modCount<>0){
       $topSpanNum = 12/$modCount; 
    }
    else{
       $topSpanNum = 0;
    }
    return $topSpanNum;
}

Thanks for posting routinet. As per your code above, when at line 5, $x variable of type JDocumentHTML is recognised. After line 6 it prints the following and dies:

When I run my original codes and it hits line 8. The module count = 0. This is incorrect as I am definitely sure the module count should equal to 3. When I test the codes with $this->countModules() on the index file. It gives the correct count.

The index.php file is currently pulling in an external file via:

require dirname(__FILE__) . '\php\htmlOutputFns.php';

Run this in place of your for loop (line 4):
    $mydie='';
    $x=JFactory::getDocument();
    for($i=1; $i<=3; $i++){
        $mydie .= "count for top-$i=".$x->countModules('top-'.$i)."<br />\n";
    }
    die($mydie);
