What is the difference between {{ }} and {!! !!} in laravel blade files?

阅读更多关于 What is the difference between {{ }} and {!! !!} in laravel blade files?

In the laravel framework we can use blade to add PHP code in html file. We are using both {{ }} and {!! !!} syntax in blade files of Laravel. What is the difference between them? Narendrasingh Sisodia Blade {{ }} statements are automatically sent through PHP's htmlentities function to prevent XSS attacks. If you pass data from your Controller to a View with some HTML styling like: $first = "<b>Narendra Sisodia</b>"; And it is accessed, within Blade, with {{ $first }} then the output'll be: <b>Narendra Sisodia</b> But if it is accessed with {!! $first !!} then the output'll be: Narendra Sisodia

Laravel 5.2 | Testing UploadedFile Misses the $test Value after Post. Bug?

阅读更多关于 Laravel 5.2 | Testing UploadedFile Misses the $test Value after Post. Bug?

问题 Update 2016/04/26 11:30 GMT+2 Workaround Since Laravel 5.2.15, the $test parameter is removed, but there is no clear reason, because Symfony's UploadedFile still has the $test parameter.
