I'm looking for a way to disable the template cache ({% cache %} tags) for the entire request based on a specific condition (not just based on the current environment). In this case, the condition is a query parameter (something like ?nocache=1), but I'm also looking for a general solution to this. There is, of course, the enableTemplateCaching general config setting, which I could use to toggle the template cache on and off:

// config/general.php

$someCondition = true;

return [
    '*' => [
         'enableTemplateCaching' = $someCondition,

The problem is that the config is included super early during the request lifecycle, before the Craft::$app object is even constructed. So I can't use Craft::$app->request->getQueryParam('nocache') or anything else from the API. For query parameters specifically, I could access $_SERVER['REQUEST_URI'] directly, but that feels kind of dirty. And it doesn't solve the problem if I need access to anything from the API to determine whether to enable caching or not.

I've checked if there's a hook in the TemplateCaches service I could use, but it doesn't look like it. The other solution would be to include the condition in every {% cache %} tag manually, but that's error-prone and noisy.

Is there a more general solution to turning off {% cache %} tags based on a specific condition for the current request?

I can't think of a different way to conditionally enable template caching (globally, i.e. not per {% cache %} tag) other than to conditionally set the enableTemplateCaching config setting to either true or false.

To your specific use case, I wouldn't worry about simply accessing the $_GET superglobal to look for that nocache param. This is essentially all that Craft itself does under the hood, when you use Craft::$app->getRequest()->getQueryParams() – except that Craft will also UTF8-encode and memoize the params, which shouldn't be critical.

So something like this should work fine:

use craft\helpers\App;

$disableTemplateCaching = App::parseBooleanEnv($_GET['nocache']);

return [
    '*' => [
         'enableTemplateCaching' = !$disableTemplateCaching,

Another option is to set the config setting a bit later in the request lifecycle. For that, you can't use config/general.php, but will need to create a custom module, adding the relevant logic within an appropriate event listener (setting/overriding the config setting can be done by accessing the Config service).

Using the craft\web\Application::EVENT_INIT event seems to work nicely; the below would go into your module's init() method:

use Craft;
use craft\helpers\App;
use craft\web\Application;
use yii\base\Event;

    static function (Event $event) {
        // Get the "nocache" query param value
        $noCacheParamValue = Craft::$app->getRequest()->getQueryParam('nocache');
        // Make sure it's a boolean
        $disableTemplateCaching = App::parseBooleanEnv($noCacheParamValue);
        // Set the enableTemplateCaching config setting using the Config service
        Craft::$app->getConfig()->getGeneral()->enableTemplateCaching = !$disableTemplateCaching;

    Thanks for the thoughtful response! You're right, the first approach should be alright, and using $_GET is indeed a bit simpler than $_SERVER. Though the second approach is even better, changing the config value on init is a great idea! Might lead to some head-scratching for other developers though, so for this approach I'll want to stick a comment in general.php explaining that the value might be changed by the module.
