Code:

function randata(){
   $chars = 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';
   $charslength = strlen($chars);
   $randomstring = '';
   for ($i = 0; $i < 15; $i++) $randomstring .= substr($chars, rand(0, $charslength - 1), 1);
   return $randomstring; 
}

{foreach $a->links as $l}
  <a href="link/{randata()}" onclick="trackClick('{randata()}');"></a>
{/foreach}


how to get the randata() to be the same value for each href and the onclick event but different for each loop so in output it would be like this:

Code:

<a href="link/erged4" onclick="trackClick('erged4');"></a>
<a href="link/evsdvd4" onclick="trackClick('evsdvd4');"></a>
<a href="link/sdcsaca" onclick="trackClick('sdcsaca');"></a>
<a href="link/asxasx" onclick="trackClick('asxasx');"></a>


Any help appriciated Very Happy

As about as random as it gets from a one-liner:

Code:
{foreach $a->links as $l}
  {$rand = substr(str_shuffle(md5(microtime())), 0, 15)}
  <a href="/link/{$rand}">trackClick('{$rand}');"></a>
{/foreach}


output:

Code:

<a href="/link/68af70ed1bb3df4">trackClick('68af70ed1bb3df4');"></a>
<a href="/link/5fa171d45ef0d93">trackClick('5fa171d45ef0d93');"></a>
<a href="/link/7f6b1fd33bfb1da">trackClick('7f6b1fd33bfb1da');"></a>

But generally speaking, I would not include application logic into template, if I were you.
