Perch Shop get category from URL
Just setting up Shop and so far I have a shop/index.php and a shop/category.php
My index.php has a simple list of categories which link to category.php where I want to display all products within each cat. My problem is that category.php is not getting the category from the slug passed from index.php. So the <title>, <h1> and list of products are just blank.
index.php (extract):
<?php perch_categories(array(
'set'=>'products',
'template'=>'category_shop.html',
)); ?>
category_shop.html template:
<perch:before><ul></perch:before>
<perch:if id="catParentID" value="0">
<li>
<a href="category.php?cat=<perch:category id="catSlug" />">
<perch:category id="catTitle" type="smarttext" label="Title" required="true" />
</a>
</li>
</perch:if>
<perch:after></ul></perch:after>
category.php:
<?php
include($_SERVER['DOCUMENT_ROOT'].'/admin/runtime.php');
perch_content_create('Page header', array(
'template' => 'page_header.html',
'multiple' => false,
));
perch_layout('header', array(
'title' => perch_category(perch_get('category'), true),
));
?>
<div class="clear">
<h1><?php perch_category(perch_get('category'), true) ?></h1>
<?php perch_content('Page header'); ?>
<?php perch_shop_products([
'category' => 'products/'.perch_get('category'),
]);
?>
</div>
<?php perch_layout('footer'); ?>
You need to look at how you're creating your links in category_shop.html and the URL parameters you're setting.
Then look at your category.php page and look at the variables you're picking up from the URL using perch_get.
The two should match.
I'm still not sure what to do from that.
cat=and'category'need to match.The products are now displaying as they should do but the code for the <h1> and <title> must still be wrong:

If you study the above,
perch_categoryis expecting 3 parameters.The first needs to be the category path (the same as you are passing to perch_shop_products).
The second is expecting an array (and can be an empty array).
The third is
trueto stop the value echoing to the page.I'm just guessing now I'm afraid...
Looking pretty good - just replace
perch_get('cat')with'products/'.perch_get('cat')(which is actually the category path).Still not working:
Oops - sorry - for that one get rid of the
, true. (And in fact, you can also get rid of the empty array).I thought we were looking at
(which you'll need to change too).
Let's do one thing at a time! First the <h1>:
This is outputting the category title as well as a bunch of template html (ul, li, h4). Is there not a more simple tag to get the catTitle only without all the extra markup?
That is because the perch_category calls the default template of category.html. You'll need to create yourself a new, simple template to pas into the function.
Your new template will just need
And you will call it like so
There's various bits of help in the documentation to help with the template thing if you haven't had to do that before...
OK thanks that's working. Now to the <title> which currently comes through blank:
Just like above, use the full cat path.
Thanks Drew and Duncan.
