   Hi Guys,
   Is there a way to limit the amount of tags returned by the_tags template tag?

   I'd like to just display the first 4 instead of all of the tags for a given post.

   Thanks!

   You could try using get_the_tags instead and then just display the first 4 tags in the returned array.

   Hey esmi,
   I tried something like this but only got one tag returned. Any help? My PHP sucks.

   <?php
   $posttags = get_the_tags();
   $count=0;
   if ($posttags) {
   foreach($posttags as $tag) {
   $count++;
   if (4 == $count) {
   echo $tag->name . ' ';
   }
   }
   }
   ?>

   Thanks!

   <?php
   $posttags = get_the_tags();
   $count=0;
   if ($posttags) {
   	$output = '';
   	foreach($posttags as $tag) {
   		$count++;
   		$output .= $tag->name . ' ';
   		if( $count >4 ) break;
   	}
   }
   echo $output;
   ?>

   @esmi can you also limit the get_tag_link to 4?

   Hey VincentvandenHeuvel did you ever figure out how to get this to return just 4 tag links? The example esmi gave just returns words, not links. Thanks.
