Convert AngularJS ng-repeat data received from Laravel API into a specific format

My Backend API is built on Laravel 5.2 and the Frontend uses AngularJS. During a Laravel validation process, I check for errors and return an error message if validation fails.

However, when I display these errors on the frontend, they appear in the format:

["The email has already been taken."]

I want to display them like this instead:

The email has already been taken.

without the [""] surrounding the message.

Here's a snippet of my code:

Angular controller:

if (error.statusText === "Unprocessable Entity") {
    $scope.registerErrors = error.data;
}

Angular template:

<div class="alert alert-warning animated pulse" ng-if="registerError && isLoading === false">
<p ng-repeat="(error, errorText) in registerErrors">{{errorText}}</p>
</div>

Laravel controller:

$this->validate($request, [
    'firstname' => 'required|max:100|min:3',
    'lastname' => 'required|max:100|min:3',
    'email' => 'required|email|unique:users|max:255',
]);

Console.log:

Thank you in advance!

Answer №1

due to the presence of errorText containing the email array and displaying the entire email array. If there are multiple errors within the email, you can attempt the following:

<p ng-repeat="(error, errorObject) in registerErrors">
  <span ng-repeat=" singleError in errorObject">{{singleError}}</span>
</p>

Alternatively, for a single error, you can try this approach:

<p ng-repeat="(error, errorText) in registerErrors">{{errorText[0]}}</p>

or simply assign error.data.email instead of error.data

if (error.statusText === "Unprocessable Entity") {
     $scope.registerErrors = error.data.email;
}

Answer №2

It is important to make a small adjustment in the code: Instead of

$scope.registerErrors = error.data;
, use
$scope.registerErrors = error.data.email;
. This change is necessary because error.data.email is an array.

In cases where multiple errors occur simultaneously, consider implementing this solution:

if (error.statusText === "Unprocessable Entity") {
      $scope.registerErrors=[];
      if(error.data.email)$scope.registerErrors.push(error.data.email[0]);
      if(error.data.firstname)$scope.registerErrors.push(error.data.firstname[0]);
      if(error.data.lastname)$scope.registerErrors.push(error.data.lastname[0]);
}

Answer №3

Here is a functional example: https://jsfiddle.net/2thqr4ej/

{{emailValidated | verifyEmail}}

Email Validation Filter:

app.filter("verifyEmail", function() {
    return function(input) {
    if(!input) return "";

    return input.substring(1, -3);
  }
});
