Looping

Im trying to get my head round more of this plugin stuff.

In vB options I have a textarea. I explode that out into an array then I want to loop each item to display in an unordered list where ever on the template.

How can I make this more compatable with vB?

PHP Code:


		
			
if($vbulletin->options['enabled'] == 1)
    {
        $items = explode("\n", $vbulletin->options['html']);
        echo '<ul>';
        foreach($items as $item)
        {
            echo '<li>'.$item.'</li>';    
        }
        echo '</ul>';
    }

Thanks :)

Your only issue is the second <ul> tag. It should be a closing </ul> instead. Aside from that it should work, as long as the $vbulletin->options['html'] variable has newline characters in it. Otherwise it will all display on one line.

As a matter of convension, you should change those option names, go with a prefix like...
$vbulletin->options['mymod_enabled']
$vbulletin->options['mymod_html']

That way nothing interferes with one another later on down the road.

Sorry that was a problem with my syntax but the original problem still exists.

How can I display this loop in a template?

Would it be best to write whatever the loop outputs to a template then include that template on another template?

If so, how would I do that?

You need to put that php in a plugin - php cannot go into a template.

Yeah I know, I've got trouble showing the contents of this plugin though.

To get it in a template, you shouldn't echo. You need to stuff it into a variable like $output_list.

PHP Code:


		
			
if($vbulletin->options['enabled'] == 1)

    {

        $items = explode("\n", $vbulletin->options['html']);

        $output_list = '<ul>';

        foreach($items as $item)

        {

            $output_list .= '<li>'.$item.'</li>';    

        }

        $output_list .= '</ul>';

    }

Then, in your template just put the $output_list variable where you want it to display. Tah-dah! The template engine will just output any variable values if you just call it..

Code:

<if condition="$vbulletin->options[mymod_enabled]">

$output_list

</if>

Can you dig it?

You may want to check if items exist in $items first.

Yeah there is.

I meant add a PHP code check, and then you can just do (in the template):

Code:

<if condition="$output_list">$output_list</if>

To simplify everything to try to root out the problem I did this:

PHP Code:


		
			
$list = 'Item1 Item2 Item3';



$items = explode(' ', $list);

        $output_list = '<ul>';

        foreach($items as $item)

        {

            $output_list .= '<li>'.$item.'</li>';    

        }

        $output_list .= '</ul>';

On the template I put this:

HTML Code:

<if condition="$output_list">

$output_list

<else />

Nothing in output_list

</if>

It just said "Nothing in output_list"

I don't know what it could be :|

What template and hooks are you placing the code in?

1Unreal

03-05-2009 10:50 AM

None, thats my full code. I didn't think I'd need to use hooks :o
