Repeater, check to see if the repeated element is first.

[quickjeff]

Hi Guys, 

I have created a slider using Bootstrap and in Bootstrap the slider image that is first in line is required to have the class active.  In creating a repeater for my client to add images, I need to add a conditional statement to check if the item is first in the repeated elements and if it indeed is first, assign active as the class. 

Not sure what is best practice using a selector and the api to see if the the repeated element is first in the repeater list.

Any light?

Thanks guys!

If I understand correctly, the usual approach is to use a counter inside your foreach.

$i=0;
foreach($sliderimage as $image){
    echo '<img ' . ($i==0 ? 'class="active"' : '') . ' src="{$image->url}" />';
    $i++;
}

Or something along those lines.

Thats right, lol. 

I used a counter for grabbing images from another template.  Totally forgot about this method. 

Thanks Adrian!
