   I'm following the instructions on this page to add some HTML to my home page that labels a post title if it has one particular tag attributed to it. My code is placed in the template's index within the loop, after the title:

   <?php	// get the post's tags
   $posttags = get_the_tags();
   if ($posttags) {
   foreach($posttags as $tag) {
   echo $tag->name . ' ';
   }
   }
   ?>
   
   <?php  // If the post is tagged with "NSFW," add:
   if ($all_the_tags);
   $all_the_tags = get_the_tags();
   foreach($all_the_tags as $this_tag) {
   	if ($this_tag->name == "NSFW" ) {
   ?>
   <span class="nswf">[NSWF]</span>
   <?php 	} else {	// if it's not, do nothing
   	}
   }
   ?>

   However, I'm getting an error on the line with foreach($all_the_tags as $this_tag) { that it's an invalid argument.

   Any ideas?

   I've done some experimenting and it seems that whatever template tag I use (get_the_tags(), the_tags(), etc.) isn't grabbing the tags associated with that post for some reason. Why would it not be grabbing the tags?

   Someone please help? I am completely stumped here...

   Finally!!! It takes a lot of digging to get any answers around here, but this thread solved my problem. And just so anyone else who comes across this doesn't get frustrated that I didn't answer my own question:

   No, I didn't have start_wp() in my code, and I was using the_post() as I was supposed to, so that was not the problem. I had to add these two lines of code to my loop just before the "while" statement:

   global $wp_query;
   $wp_query->in_the_loop = true;

   And then this was the final code I used to add a message to my post titles if they were tagged with this particular tag:

   <?php
   $posttags = get_the_tags();	// get the post's tags
   if ($posttags) {
   foreach($posttags as $tag) {
   	if ($tag->name == 'NSFW') {	// If the post is tagged as "NSFW," add:
   ?>
   	<span class="nsfw">[NSFW]</span>
   <?php 	} else {	// if it's not, do nothing
   		}
   	}
   }
   ?>

   Thank you so much AsraiLight.

   The tags was not showing up for me either, until i added the code before the while statement.

   Thanks very much!

   You really should look at using has_tag, more efficient.

   For use inside the normal loop, no need for any of that foreach loop above..
