In the docs it states that all channel:entries parmeters can be used as dynamic parameters.

What’s the correct way to set up multiple categories in this way, e.g. a list of category checkboxes. I’m thinking something like the following (where the categories tag generates the list of available categories for inputs):

<form method="post" action="{path='{segment_1}/{segment_2}'}">
{exp:channel:categories
 channel="news"
 category_group="2"
 parent_only="yes"
 show_empty="no"
 style="linear"
}
<label for="cat1">
 <input type="checkbox" id="cat1" name="category[]" value="{category_id}">{category_name}
</label>
{/exp:channel:categories}
</form>

All other dynamic parameters are working fine, but I can’t get these multiple categories to work. Has anyone ran into a similar problem?

Just to confim, I’m not having a problem with the output of the categories tag, that’s working fine.

What I’m having a problem with is generating the dynamic entries, which don’t seem to filter on the categories when submitting the form.

Hi willm,

Thanks for your question!

Have you tried hardcoding one category ID, to see if that works?

The challenge here is that the category parameter in channel entries accepts a pipe delimited list, and your checkbox input are going to be passed over as an array.

Try this:

<input type="checkbox" id="cat1" name="category[]" value="{category_id}|">{category_name}

I added the “|” to the end of the ID value. That should build the proper list for the category parameter.

I look forward to your reply!

Cheers,

Checking out some other forum posts, it seems category[] can’t be used to join parameters in conjunction with dynamic parameters. It can be done with Dynamo though!

One thing that EE can’t do, but would be really useful, is being able to use both a pipe and ampersand to join category parameters. At present you can only use them on their own, but it would be great if you could do this:

category="1&4|1&5|1&6"

It would make filtering a lot more flexible! I’ll submit it as a feature request

Hi willm,

Excellent idea!

Thanks for sharing your find of Dynamo as well!

Is there anything else I can assist you with?

Cheers,

No that’s fine thanks Dan. Thanks for your help!

Hi willm,

Fantastic!

If you need anything else, just let us know.

Cheers!
