Toggle content via a checkbox problem

Hi,

The setup below allows me to toggle a message, via a checkbox in the page attributes.

I can only get it to work properly if I remove suppress from the perch:pages template, but that outputs the value to the page when the checkbox is ticked.

My setup

toggle-newsletter-banner.html is in pages/attributes

<perch:pages id="toggle_nlb" label="Hide newsletter banner" type="checkbox" value="1" >

It displays a checkbox in the page details tab.

I'm using this code (from this post) to check if the checkbox has been ticked

$toggle = perch_page_attribute('toggle_nlb', [
'template' => 'toggle-newsletter-banner.html'
], true);

if($toggle) {
// do something if checkbox is checked
echo "checkbox is checked";
} else {
// do something if checkbox is unchecked
echo "checkbox is UNCHECKED";
}

This mostly works.

However, because I've not set suppress on perch:pages id="toggle_nlb" the value is output to the page when the checkbox is ticked.

When I add suppress to the template...

<perch:pages id="toggle_nlb" label="Hide newsletter banner" type="checkbox" value="1" suppress >

checkbox is UNCHECKED is output when the checkbox is ticked or not.

Any ideas why?

Do you call perch_page_attributes() somewhere? Perhaps in your <head>? It might be what's outputting your checkbox value.


I think you can use skip-template instead, which enables you to read the field's value regardless of whether you're using suppress:

$attrs = perch_page_attributes(['skip-template' => true]);

if($attrs['toggle_nlb']) {
    // checked
} else {
    // not checked 
}

Hi Hussein,

Thanks for taking the time to respond to this post, really appreciate it.

Yes, perch_page_attributes was being called in the head. I completely forgot about skip-template.

Your solution works great! Many thanks.

Great!

Normally in the <head> I like to specify the template like so:

 perch_page_attributes(['template' => 'seo.html']);

So when you add additional attributes to pages/attributes/default.html they won't be output in the <head>.
