Hi!

I have a template showing all entries from a channel and I wish to add a filtering form by category something like this.

<form method="post" action="">
    <input type="checkbox" name="category" value="3"> Category 1
    <input type="checkbox" name="category" value="4"> Category 2
    <input type="checkbox" name="category" value="5"> Category 3
    <input type="submit" name="submit" value="submit">
</form>

Is this possible to implement this idea. Once a user will click submit then the choosen categories will only show in the Template?

I tried this but no luck..

This is on top of the template

$cat1 = $this->EE->input->post('cat1');
$cat2 = $this->EE->input->post('cat2');
$cat3 = $this->EE->input->post('cat3');
$categories = "";
        
if ( $cat1 == "1" ) {
    $categories = $categories . "1";
} 
    
if ( $cat2 == "2" ) {
    $categories == "" ? $categories = $categories . "2" : $categories = $categories . "|2";
}
        
if ( $cat3 == "3" ) {
    $categories == "" ? $categories = $categories . "3" : $categories = $categories . "|3";
}

In the end of the PHP code $categories will be “1|3” if the 1st and 2nd checkboxes are checked.

I am trying to to this in the channe tag, somthing like this but this won’t work..

{exp:channel:entries channel="{preload_channel}" category="<?php echo $categories?>"}

I tried this as well

{preload_replace:pre_categories="<?php echo $categories?>"}
{exp:channel:entries channel="{preload_channel}" category="{pre_categories}"}

My preload_channel is working but my preload_categories wont but I can view it by just simply calling the tag {pre_categories}

Can anyone help me?

Thanks…

You should be able to do this; do you have the “PHP Parsing Stage” set to input or output?  I believe you will need it set to input.

I would try something like this real quick as a proof of concept.

<?php $categories = '3'; ?>
{exp:channel:entries channel="{preload_channel}" category="<?php echo $categories?>"}

Thanks Tom!

But upon changing the PHP parsing to INPUT, all of my codes are showing in the browser already.

When you mention all of your codes showing in the browser, do you mean your PHP?  If so it almost sounds like “Allow PHP” got set to no.

I found an error at the bottom of my page. I have a PHP there which is not parsing well. It is just strange that it parsed when the parsing stage is OUTPUT.

Anyway. Thanks for your help Tom. You saved my day.
