What validation rule can i use to accept only html code like above?

$validator=Validator::make($request->all,[
            'cartTemplate'=>'nullable|string'
        ]);

CodePudding user response：

$regex = "/<(/)?(body|html|head|p|b|strong|a|i|span|div)*>/"

  if (preg_match($regex, $textViewValue) {
     // contains an HTML tag
  } else {
     // doesn't contain an HTML tag
   }

For this problem, I'd be using regular expressions.

CodePudding user response：

There is no specific validation rule in Laravel to check it is valid HTML But Laravel gives the option to add a custom rule.

php artisan make:rule HtmlChecker

In custom rule define the regex for HTML and add it in Laravel Validator
