Blog if else statement for no tags returned
I thought I was just trying to achieve something fairly simple, but for whatever reason, I cannot get it to work.
On a blog app installation, I am using categories and tags to help aid in blog entry archiving, searching etc....as most people do.
At the bottom of each blog entry I am listing the categories and tags that are associated with that individual entry.
What I would like to do is return a value/message when, for example, the entry doesnot have any tags.
Currently, my thought was to use the 'if exists' route for the perch_item_index, with the theory being, if there is no index value, then there are no tags and as such, display a message. The code I have is:
<perch:before>
</perch:before>
<perch:if exists="perch_item_index">
<perch:if exists="perch_item_last">
<a href="archive.php?tag=<perch:blog id="tagSlug" />" rel="tag"><perch:blog id="tagTitle" /></a>
<perch:else />
<a href="archive.php?tag=<perch:blog id="tagSlug" />" rel="tag"><perch:blog id="tagTitle" /></a> |
</perch:if>
<perch:else />
<p>No Tags</p>
</perch:if>
<perch:after>
</perch:after>
The first if, I thought would have just been the trigger to pick up that either tags existed, or didn't for that entry. The sub perch:if is purely for styling.
Any thoughts as to why my 'No Tags' message is not displaying.
Works fine, if tags are present.......
Templates aren't normally rendered if they don't have any content, unless they use a
noresults
section.Have you tried that?
Just tried adding a 'noresults' element to the current solution, as such:
No joy. Will look at trying some other things.
Thanks
Ok, got it working. I should have read / googled this more before I posted, so my apologies. I was in a rush/stressed.
For anyone who is interested, to get the 'noresults' element working, you need to use a custom function. So, in my example, from the Blog post.php page I originally called the tags with:
Now, I use a custom call:
This, with the changes to my template (as shown in above reply) result in a working solution.
Thanks Drew for putting me on the correct path !!
Ooops, sorry everyone. The above does not work.
Back to the drawing board. I will edit things, as soon as I can figure out a solution to this.
