$config→setLocation() not working as intended

[Torsten Baldes]

Hi,

I'm in the process of relaunching a site of mine and wanted to build and test it side by side with the current site.

I tried to set the template folder in ready.php for some users with $config→setLocation() to a different folder (as described here):

$userNamesWithDevAccess = ['testuser'];
if(in_array($user->name, $userNamesWithDevAccess)) {
	$config->setLocation('templates', 'site/templates-dev/');

	echo '<pre>';
	var_dump($config->urls->templates);
	var_dump($config->paths->templates);
	echo '</pre>';
}

This seems to work as intended:

string(21) "/site/templates-dev/"
string(54) "/Users/myaccount/mysite/site/templates-dev/"

But when I go to my frontend, there's only a blank page besides my var_dump. (Same blank page when I remove the var_dump test.)

If I go to the backend I get the following error message:

Hey now… Error: Exception: Missing or non-readable template file: site/templates-dev/site/templates/admin.php (in wire/modules/PageRender.module line 584)

#0 wire/core/Wire.php (416): PageRender->___renderPage(Object(HookEvent))

#3 wire/core/WireHooks.php (1094): Wire->__call('renderPage', Array)

#9 wire/core/Wire.php (484): WireHooks->runHooks(Object(ProcessPageView), 'execute', Array)
#10 index.php (55): Wire->__call('execute', Array)
#11 {main}

(I modified the line 584 in PageRender.module to output the whole path.)

So looking at the path (site/templates-dev/site/templates/admin.php), it seems the system prepends the new path to the old path. Which is probably also the reason for the blank pages at the frontend.

Is this a bug, or am I doing something wrong?

Thanks!
