Perch:before showing even when no results are returned

SixTillNine · May 12th 2019

Hello,

I'm calling in region information from another page and filtering the results. However when no results are returned the <perch:before> and <perch:after> sections are still being shown.

The filters work fine and only show the information associated with the current page - however when there isn't any information associated it still returns the before and after code.

Code

PerchSystem::set_var('practiceFilter', $pagePath);
perch_content_custom('Course Dates', [
'page' => '/course-dates.php',
'template' => 'courses/course_snapshot_practice.html',
'sort' => 'date',
'sort-order' => 'ASC',
'filter' => 'courseSubject',
'match' => 'eq',
'value' => $pagePath
]);

The template is as follows:

Code

<perch:before>
<div class="courseList section">
<div class="wrapper">
<h4><perch:content id="pageTitle"/> Courses & Workshops</h4>
<p><a href="/courses-workshops" title="View all courses...">View all courses...</a></p>
<ul>
</perch:before>
<perch:if id="today" match="lte" value="{date}">
<li>
<a href="/course-details?course=<perch:content id="_id" />" title="">
<h4><perch:content id="courseTitle" type="text" html="true"/></h4>
<p class="date"><perch:content id="date" format="l jS F H:i" /></p>
<p><perch:content id="courseSubject" /></p>
<p><perch:content id="courseSubject" type="pagelist" output="pageTitle" /></p>
<p><perch:content id="_id" /></p>
</a>
</li>
</perch:if>
<perch:after>
</ul>
</div>
</div>
</perch:after>

Hello SixTillNine

This is because there are some results but you are not outputting them (because of the conditional tag inside the template). If you move your filtering logic outside of the template, you should get the behaviour you want:

PHP

perch_content_custom('Course Dates', [
'page' => '/course-dates.php',
'template' => 'courses/course_snapshot_practice.html',
'sort' => 'date',
'sort-order' => 'ASC',
'filter' => [
[
'filter' => 'courseSubject',
'match' => 'eq',
'value' => $pagePath
],
[
'filter' => 'date',
'match' => 'lte',
'value' => $today
]
]
]);

Thanks Hussain, I wasn't aware that was possible.
