AngularJS ngRepeat is not complying with the limitTo filter

Currently, I am using ng-repeat to display a list of available supermarket items. These items are fetched in JSON format using $http and stored in $scope.items. The ng-repeat function is working perfectly in displaying all the items. However, my challenge lies in limiting the number of displayed items to only 3 out of the 20 available items. I have attempted to use a limitTo filter without success. Despite specifying the filter, the screenshot provided shows that all items are still being displayed:

Below is the snippet of the HTML code I am using:

<span class="item-choices-choice pull-left">
    <ul>
         <li ng-repeat="choice in items.0 | limitTo:3">
             <img src="{[{ choice.ImagePath }]}" class="img-rounded" /> {[{ choice.Name }]} <strong>{[{ choice.Price }]}</strong>
         </li>
    </ul>
</span>

Any assistance on this issue would be greatly appreciated.

EDIT:

Just to provide more context, I want to clarify that I have replaced {{ with {[{ in AngularJS to avoid conflicts with Twig.

The 'items' variable is initialized as an array in the controller:

$scope.items = [];

Here is the JSON data received from the AJAX request:

Despite AngularJS working correctly in other scenarios, it seems to be facing an issue specifically with this particular case.

Answer №1

The issue has been successfully identified.

Upon further investigation, it appears that when using json_encode with an ArrayIterator in PHP, it encodes it as an object within an object rather than an object in an array. This in turn leads to complications with the limitTo (and other) filters in Angular not functioning correctly.

By converting the ArrayIterator into a standard PHP array and then utilizing json_encode, the limitation functions flawlessly.

Answer №2

Your syntax for interpolation is incorrect. Instead of using square brackets within curly braces, you should use double curly braces.

<img src="{{ choice.ImagePath }}" class="img-rounded" /> {{ choice.Name }} <strong>{{ choice.Price }}</strong>

Once you make that change, it should work properly in this codepen.
