Check if page exist else show ...

Recommended Posts

Hello

I'm not a coder so would appreciate some help with PHP.

I created simple even calendar and all is working great so far.

I'm using next to fetch my events. Every event is a page.

<h2>My Header for events</h2>

<?php $events = $pages->find('template=calendar-post, limit=5, Start_date|End_date>=today, sort=Start_date'); ?>
	<?php if(count($events)): ?>
		<?php foreach($events as $single): ?>
          my events code!
<?php endforeach; ?>
<?php else: ?>
		<div>There are no events at the moment!</div>
<?php endif; ?>	

But I would like to change this and hide the entire section including the <h2> if there are no events, how can I do that. Meaning that I would then remove (There are no events .... from the code). Not sure how to check if page (template=calendar-post, Start_date|End_date>=today, sort=Start_date') exists.

Hope you uderstand

Thank you

Assuming I understood the question...one way to do it:

<?php namespace ProcessWire;

// init empty string to store markup output
$out = "";

$events = $pages->find('template=calendar-post, limit=5, Start_date|End_date>=today, sort=Start_date');

// we found events
if($events->count()){

    $out .="<h2>My Header for events</h2>";
    // my events code!
    // start list - just an example
    $out .= "<ul>";
    foreach($events as $single) {
        $out .= "<li>{$single->title}</li>";
    }
    // close the list
    $out .= "</ul>";
}

// use this if you need to show 'no events info'
else {
    $out .= "<div>There are no events at the moment!</div>";
}

echo $out;

Please note, I haven't checked the validity of your selector.

Thank you very much I already had everything just not in the right place. All I had to do was to place 

<?php $events = $pages->find('template=calendar-post, limit=5, Start_date|End_date>=today, sort=Start_date'); ?>
	<?php if(count($events)): ?>

above everything. Figured it out thanks to your example 😉

Thank you
