Perch Global Var

Hi All

Is there a way to set a global variable using PHP that can then be used in any template...

what i want to do is use <perch:if exists="" /> to display tab or accorian on mobile

the site has been built and full with content so its too late to change form perch_content to perch_content_custom

Any ideas?

Yes, use PerchSystem::set_var()

the site has been built and full with content so its too late to change form perch_content to perch_content_custom

Then the templates have already been evaluated and compiled to HTML, so no variables at runtime will affect them.

Hi Drew

Issue is when i do this

PerchSystem::set_var('device', $device);
perch_content('content');

the variable does not appear when i use <perch:showall />

but i cant use perch_content_custom as the client needs to choose from 3 templates that all use blocks

I'm not sure I follow. perch_content_custom() and perch_content() will both render blocks.

So to make the variable appear i need to use perch_content_custom()

but to use perch_content_custom() i then need perch_content_create()

issue i then have is a template needs to be specified when using perch_content_create() the user cant choose

That's no the case. Or at least, that's no supposed to be the case.

You can replace this:

perch_content('content');

with this:

perch_content_create('content')
perch_content_custom('content', []);

Hi Drew

i just tried that so i have the following

require_once ($_SERVER['DOCUMENT_ROOT'].'/perch/functions/mobile_detect/mobile_detect.php'); 

$detect = new Mobile_Detect;
// Any mobile device (phones or tablets).

if ( $detect->isMobile() ) {
    $device = "mobile";
} else {
    $device = "desktop";
}


PerchSystem::set_var('device', $device);
perch_content_create('content');

perch_layout('global/header');

perch_content_custom('content', []);

echo '<pre>';
print_r(PerchSystem::get_vars());
echo '</pre>';


perch_layout('global/footer');

But when i create a new page there is no region

I think the main issues are

0.1286 0.001 No matching content regions found. Check region name (content) and page path options.

0.1296 0.001 Template file not found: /var/www/landandwave/perch/templates/content/.html

As yet, I can't see why that isn't working. Have you tried an isolated example? You obviously have a lot going on on that page.

Hi Drew

i just tried with a new template and a new page

<?php
PerchSystem::set_var('device', 'Mobile');

perch_content_create('content');

perch_layout('global/header');

perch_content_custom('content', []);

echo '<pre>';
print_r(PerchSystem::get_vars());
echo '</pre>';

perch_layout('global/footer');

And the same issue no region

Even tried without the header and footer and no luck

PerchSystem::set_var('device', 'Mobile');

perch_content_create('content');

perch_content_custom('content', []);

echo '<pre>';
print_r(PerchSystem::get_vars());
echo '</pre>';

Ok, getting the same here.

Do this instead:

perch_content('content', false);  
perch_content_custom('content', []);
