layout:set not passing data when inside channel:entries tag
Development and Programming
Hi. I’m using a site/_wrapper layout template and, pushing data using layout:set from the parent template (site/index). For example:
{layout="site/_wrapper"}
{layout:set name="body_class"}{template_group} {template_name}{/layout:set}
{exp:channel:entries channel="pages" disable="categories|member_data|pagination"}
{layout:set name="meta_title"}{title}{/layout:set}
<h1>{title}</h1>
{/exp:channel:entries}I am getting an issue where the body_class variable passes through fine but the meta_title one inside the entries tag does not. The title does display so the entries tag is returning data. The debug actually lists the meta_title one under undefined variables in this scenario. I’ve also tried test data with the meta_title one outside the entries tag to check the variable was correct and that does pass data through.
If I reverse it round so the entries tag is inside the layout:set like this…
{layout:set name="meta_title"}{exp:channel:entries channel="pages" disable="categories|member_data|pagination"}{title}{/exp:channel:entries}{/layout:set}…then that does pass the variable data. So it looks like the layout:set tags are not being processed inside the entries tag.
This is using EE 7.3.14 on PHP8.2. I came across this issue running it on MAMP on my local system but have since set it up on a live server and I’m still getting the same issue.
Is there a bug in this version or have I missed something?
Thanks for any help.
Hi there. Did you try changing the layout variable name? Like maybe “meta_title_custom” or something like that? I usually find when I have one variable that works and another that doesn’t it is because of clashing variable names.
Hope thats of some help.
One other thing… You CAN set layout tags within a Channel Entries tag pair, but I think only if you are expecting only a Single entry to be returned. If there are more than a single entry you may need to look at {layout:set:append} tags.
Thanks Russ. I’ve tried renaming but still no joy. That entries tag should only have a single entry (I’ve got limit=”1” and require_entry set on it now on the actual template). I’ve often used this approach to push meta data and other information based on the entry’s content to a wrapper template so I can customise the display so it’s a bit strange why it’s not working this time.
Just to confirm, this is the full code in the index template so far:
{layout="site/_wrapper"}
{!-- <!-- Template: site/index || Home --> --}
{layout:set name="breadcrumb"}<a href="http://{path=contact}">Contact us</a>{/layout:set}
{layout:set name="body_class"}{template_group} {template_name}{/layout:set}
{exp:channel:entries channel="pages" entry_id="2" disable="categories|member_data|pagination" dynamic="no" limit="1"}
{layout:set name="meta_title_custom"}{title}{/layout:set}
{layout:set name="meta_description"}{meta_description}{/layout:set}
{layout:set name="meta_custom"}{meta_custom}{/layout:set}
<!-- other field content to be added -->
{/exp:channel:entries}…and then the _wrapper template:
{!-- <!-- Template: site/_wrapper --> --}
<!doctype html>
<html>
<head>
<meta charset="{charset}">
<title>{layout:meta_title_custom} | {site_name}</title>
<link rel="stylesheet" href="{stylesheet=site-css/nium-core.css}">
</head>
<body class="{layout:body_class} {layout:title_section_class}">
<a href="#main" class="skiplink">Jump to content</a>
<div class="site-outer">
<div class="site-content">
<header id="header" class="site-header">
<div class="site-header-inner">
<div class="site-title"><a href="http://{homepage}">{site_name}</a></div>
<nav id="nav" class="site-nav">
<input id="display_nav" type="checkbox" value="y">
<label for="display_nav"><span>Show navigation menu</span></label>
<div id="nav_menu" class="menu"><!-- menu to go here --></div>
</nav>
{/exp:channel:entries}
{if layout:breadcrumb}<div class="breadcrumb">{layout:breadcrumb}</div>{/if}
</div>
</header>
<main id="main" class="site-main">{layout:contents}</main>
<footer id="footer" class="site-footer"></footer>
</div>
</div>
</body>
</html>I’ve include a screenshot of the variables info from the debug where you can see the meta_title_custom is undefined (title_section_class is one that will be added for layout options but I’m having the same issue with that when trying to use it in an entries tag).
I’ve just tried it disabling custom_fields in the entries tag and the title is pushed through fine to that variable so maybe the issue is elsewhere rather than with the variables. I’ll try a few more options and see if I can track it down!
Thanks. I’ve tried a few other things since, but it looks like increasing the server setting for max_input_vars appears to have solved it (was 1000, set to 2000).
