Understanding how to handle the responseText in Laravel when it is returned as a JSON string

Here is the Laravel code snippet:

public function validateRegisterToBidForm(Request $request){

    $validationArray = $this->getValidationArray();

    $this->validate($request, $validationArray);
    return response()->json();

}//validateRegisterToBidForm

The output from the above code is retrieved via Ajax. In case of an error, the output is stringified and returns a JSON like this:

{"readyState":4,"responseText":"{\"fname\":[\"This field is missing or incorrect.\"],\"lname\":[\"This field is missing or incorrect.\"],\"email\":[\"This field is missing or incorrect\"],\"password\":[\"This field is missing or incorrect.\"],\"adr1\":[\"This field is missing or incorrect.\"],\"city\":[\"This field is missing or incorrect.\"],\"state\":[\"This field is missing or incorrect.\"],\"phone\":[\"This field is missing or incorrect.\"],\"primary_phone\":[\"This field is missing or incorrect.\"],\"pass_dri_license\":[\"This field is missing or incorrect.\"],\"card_type\":[\"This field is missing or incorrect.\"],\"cardno\":[\"This field is missing or incorrect\"],\"cvv\":[\"This field is missing or incorrect.\"],\"fname_b\":[\"This field is missing or incorrect.\"],\"lname_b\":[\"This field is missing or incorrect.\"],\"email_b\":[\"This field is missing or incorrect.\"],\"adr1_b\":[\"This field is missing or incorrect.\"],\"city_b\":[\"This field is missing or incorrect.\"],\"state_b\":[\"This field is missing or incorrect.\"],\"phone_b\":[\"This field is missing or incorrect.\"],\"primary_phone_b\":[\"This field is missing or incorrect.\"]}","status":422,"statusText":"Unprocessable Entity"}

Now the question arises: How can we extract values from this JSON object? What would be the correct method?

Answer №1

If you need to make a call like this:

 $.ajax({
        type: "POST",
        url: "the/url",
        data: {the: data},
        success: function (myresponse) {
            console.log(myresponse);
        },
        error: function(xhr, status, error) {
            var err = JSON.parse(xhr.responseText);
            console.log(err);
        }
    });

In my experience, I often use JSON.parse(); in order to access individual fields using the err variable such as err.fname

I trust this information will be useful to you :)
