Getting error Invalid template file

Question

I'm new to Magento and when first installed on my localhost there was no errors, but yesterday setting up second project of Magento on my localhost the following errors appeared:

[2019-12-20 13:17:30] main.CRITICAL: Invalid template file: 'F:/xampp/htdocs/magento2/vendor/magento/module-backend/view/adminhtml/templates/page/js/require_js.phtml' in module: 'Magento_Backend' block's name: 'require.js' [] []

[2019-12-20 13:17:30] main.CRITICAL: Invalid template file: 'F:/xampp/htdocs/magento2/vendor/magento/module-ui/view/base/templates/wysiwyg/active_editor.phtml' in module: 'Magento_Ui' block's name: 'theme.active.editor' [] []

Please help that how can I resolved it?

Answer 1

I got the Solution as below,

foreach ($directories as $directory) {
    if (0 === strpos($realPath, $directory)) {
        return true;
    }
}

Currently we can go for a dirty quick change in the above foreach loop so that we can run our magento with no further problems on this:

#/vendor/magento/framework/View/Element/Template/File/Validator.php:139
foreach ($directories as $directory) {
    // Add this line
    $realDirectory = $this->fileDriver->getRealPath($directory);
    // and replace `$directory` with `$realDirectory`
    if (0 === strpos($realPath, $realDirectory)) {
        return true;
    }
}

Firstly I think it is important to explain the reason why the error is occuring... The error is occurring because of the backward slashes on the path that should be replaced with a forward slash in Windows. The more "cleaner" alternative (that I prefer) is to not touch the foreach loop and instead add this line of code immediately above the loop:

$realPath = str_replace('\\', '/', $realPath); this line of code is declarative and hence more readable, it's purpose can be understood at first glance. it serves to replace the backward slashes on the path with a forward slash...the function would then be as follows:

protected function isPathInDirectories($path, $directories)
{
    if (!is_array($directories)) {
        $directories = (array)$directories;
    }
    $realPath = $this->fileDriver->getRealPath($path);
    $realPath = str_replace('\\', '/', $realPath); // the line we added
    foreach ($directories as $directory) {
        if (0 === strpos($realPath, $directory)) {
            return true;
        }
    }
    return false;
}
