In Laravel, you can use the has method provided by the Request class to detect if a field has input. The has method allows you to determine if a particular input field is present in the request data.


Here's an example of how you can use the has method in a controller method:

 1

 4
 5
 6
 7
 8
 9
10
public function store(Request $request)
{
    if ($request->has('field_name')) {
        // Field has input
        // Your code here
    } else {
        // Field does not have input
        // Your code here
    }
}


In the above example, the has method is used to check if the input field with the name 'field_name' is present in the request data. You can replace 'field_name' with the name of the field you want to check for input.


If the field is present in the request data, the has method will return true, and you can execute the code inside the if block. If the field is not present, the has method will return false, and you can execute the code inside the else block.
