Hi-

I’m trying to build a conditional that reacts based on whether an entry is a member of a certain category.

If I code the following:

{categories}
{category_id}
{/categories}

I get “1 4 5” (indicating the categories to which this entry belongs.)

However, if I code this:

{categories}
    {if category_id=="4"}
      ...do stuff…
    {/if}
{/categories}

the {categories} tags don’t parse. They display in the page, and none of my conditional gets executed.

Can someone please explain the proper syntax for building a conditional which uses a category_id within {exp:channel:entries} tags?

Thanks

Any thought? The version 1.x code from this wiki isn’t working in EE2.

http://expressionengine.com/wiki/Conditional_Based_On_Category

try…

{categories}
    {if "{category_id}" == "4"}
      ...do stuff…
    {/if}
{/categories}

?

Interesting…the code you posted worked, as did the original non-conditional code.

However, when I put in my “do stuff” code (which is another set of convoluted if/else statements to handle date formatting for an events page), the {categories} tags do not get parsed. They render as text in the template. So looks like the code I’m inserting within the categories tags is breaking something.

Here’s the full code of what I’m attempting to do:

{categories}
    {if "{category_id}" == "4"}
        {if expiration_date}
            {if "{entry_date format='%F %j %Y'}" == "{expiration_date format='%F %d %Y'}"}
                {entry_date format='%F %j, %Y <br /> %g:%i%A'} - {expiration_date format="%g:%i%A"}
            {if:else}
                {entry_date format='%F %j'} - {expiration_date format='%F %j, %Y'}
            {/if}
        {if:else}
            {if "{entry_date format="%H:%i"}" != "00:00"}
                {entry_date format='%F %j, %Y   %g:%i%A'}
            {if:else}
                {entry_date format='%F %j, %Y'}
            {/if}
        {/if}                                                               
    {/if}
{/categories}

Hi Ed,

I make sure you are consistent in the use of double and single quotes. That could be confusing the parser. Try this:

{categories}
    {if "{category_id}" == "4"}
        {if expiration_date}
            {if "{entry_date format='%F %j %Y'}" == "{expiration_date format='%F %d %Y'}"}
                {entry_date format='%F %j, %Y <br /> %g:%i%A'} - {expiration_date format='%g:%i%A'}
            {if:else}
                {entry_date format='%F %j'} - {expiration_date format='%F %j, %Y'}
            {/if}
        {if:else}
            {if "{entry_date format='%H:%i'}" != "00:00"}
                {entry_date format='%F %j, %Y   %g:%i%A'}
            {if:else}
                {entry_date format='%F %j, %Y'}
            {/if}
        {/if}                                                               
    {/if}
{/categories}

It may not be evident, but I changed a few doubles to singles 😉

Cheers!

Thanks for the tip, Dan. I do see what you mean about the single and double quotes, and that’s a good reminder for me.

Unfortunately, no luck! I cut/pasted your code block, and unfortunately got the same error.

All I see in the rendered template is {categories}{/categories}

Ok Ed,

Thanks for at least entertaining my idea! Let’s get this sorted out. Can you tell me what version of ExpressionEngine 2 you are running and can you post the entire contents of the template that is affected? I’d like to be able to replicate this as accurately as possible, but I want to rule out anything else in the template that might be a factor here.

Cheers!

Hi Dan-

Thanks for your diligence! Unfortunately, after I was unable to find a solution with the categories tag, I reworked the template to present the information differently. So I no longer have the issue with my template, but it’s not because I was able to find a solution to my problem with the {categories} tag.

Thank you anyway for volunteering your assistance.

Best,

Ed

Ed,

Good to see that you were able to come up with an alternate solution. I’m going to close out this thread, but feel free to post again when you have more questions.
