Show field only if repeater matrix field has content

[Tyssen]

I'm upgrading an old PW site which originally just had a single body field and now giving them a repeater matrix field which will allow more types of content.

For the template, if the repeater matrix field has content I want to hide the old body field from the editor. What would be the conditional that I'd enter into the settings for the body field? I thought it might be something like matrix_content.count=0 but that doesn't work.

Try in your template:

<?php 
// assuming 'matrix' is the name of your repeater matrix field
if($page->hasField('matrix') && $page->matrix->count > 0) : 
	echo $page->render('matrix');
else:
	echo $page->body;
endif; ?>

That would be on the front end. I was talking about the field settings so that the old field doesn't show in the admin if the new field has content.

You could try https://processwire.com/docs/fields/dependencies/

Yes, that's what I've already been looking at. What I don't know is what selector to put in the show-if dependencies field. If it was a checkbox it would be checkbox_field=1 but I don't know what the format should be for repeater matrix fields.

Hi @DV-JF

Unfortunately, count is not a field. You cannot use your_reapeater.count in the showif setting.

Hi @Tyssen

You can add a hidden field to the template and then update the field whenever the page is saved by using a saveReady hook. Then you can use this field in the showif setting.

So no way to do it without having to fiddle around with extra fields? It's not that important if the field still shows, so if there's not a simple straight forward to do, I'll leave it as is.
