PHP Notice: Undefined index: title...

granttransition · Feb 14th 2019

I am getting a PHP Notice: Undefined index: title on line 13 of the following code.

PHP: /page/locations/detail.php

<?php
$locations = perch_collection('Locations', [
'filter' => 'slug',
'match' => 'eq',
'value' => perch_get('s'),
'template' => 'locations/item_detail.html',
'skip-template' => true,
'return-html' => true,
]);
if(isset($locations[0])) {
// exists - let's grab the title
$page_title = $locations[0]['title'];
PerchSystem::set_var('current_page_title', $page_title);
} else {
// doesn't exist - let's redirect to the 404 page
PerchSystem::redirect('/errors/404');
}
perch_layout('global/page-head', [
'meta' => 'locations',
]);
perch_layout('global/header');
// output the item
echo $locations['html'];
perch_layout('other_locations');
perch_layout('global/footer');
?>

It seems unhappy $page_title = $locations[0]['title'];. But I can't figure out why?

The Locations Collection this refers to has <perch:content id="title" type="text" label="Title / Heading" required title> in the item.html file. I thought it might not like the way I've written the title id. However it doesn't seem to make a difference?

Thanks in advance

I found my switch in page-head.php had an error.

PHP: Working code

switch(perch_layout_var('meta', true)) {
case 'locations':
perch_collection('Locations', [
'template' => 'locations/meta_head.html',
'filter' => 'slug',
'match' => 'eq',
'value' => perch_get('s'),
]);
break;
