Laravel Validation for Multiple input values

Question

I am working on the Laravel Validation code. In my code, I used the radio button for three options like approve, reject, and return. In the Remarks textbox, validation depends on the Radio button values. Without choosing any options, the validation is working fine, like "Please choose any one." If I choose the Approve option, then the Remarks textbox validation shows an error like "Please enter remarks for your approval". If I choose the Reject Option, it shows an error like "Please enter remarks for rejection."

<input type="radio" id="approve" name="radiooption" value="-1">
<input type="radio" id="reject" name="radiooption" value="R">
<input type="radio" id="return" name="radiooption" value="A">
<input type="text" value = "Remarks" name = "remarks" >



$validated = $request->validate([            
            'radiooption'   => ['required'],
            'remarks' =>  ['required_if:radiooption',-1,'A','R']
            ]
            [
            'radiooption.required' => 'Please choose one of the action.',
            'remarks.required_if' => 'Please enter reason(s) to applicant :values',

]

Above is not working, It shows error like Validation rule required_if requires at least 2 parameters. Please support me to solve that issue

How should it work instead? Please post that information in your question. — Peter Pointer

Sidenote, you're using id="radiooption" 3 times, but ids need to be unique, or use class="radiooption" instead. No effect on your current issue (which is a syntax error on usage of required_if: laravel.com/docs/10.x/validation#rule-required-if), but if you ever tried to target document.getElementById('radiooption'), you'd run into issues. — Tim Lewis

The syntax for your validation seems incorrect, required_if can take multiple values to check against the field. While the usage of | seems incorrect, normally the values would be separated in the string like this required|string, you are doing it outside the string.

 'remarks' => ['required_if:radiooption,1,2,3']
