in_array method on volt


How can i use in_array() function on Volt?

I searched on volt doc but i couldnt about that.

I tried in operator but doesnt work with arrays.

{% if id in array %}
    // todo
{% endif %}

You have to add it in your Service defintion:

$di->set('view', function() use ($di) {
    $view = new \Phalcon\Mvc\View();
    $view->setViewsDir(__DIR__ . '/views/');

    $view->registerEngines(['.phtml' => function($view, $di) {
        $volt = new \Phalcon\Mvc\View\Engine\Volt($view, $di);
        $options = [
            'compiledPath' => $di->getConfig()->site->path->cache . 'volt/backend/',
            'compiledExtension' => '.php',
            'compileAlways' => $di->getConfig()->debug,

        // Extended functions
        $compiler = $volt->getCompiler();
        $compiler->addFunction('in_array', 'in_array');
        $compiler->addFunction('is_dir', 'is_dir');
        $compiler->addFunction('getimagesize', 'getimagesize');
        return $volt;

    return $view;

Here is a link with all built in Volt functions.

To add other functions or create your own refer to the code above.

I'm already using addFunction but i was expecting direct volt feature ;))

Nah, not all php functions are registered in Volt. Its not needed, since most are situationaly based and you can easily add them.

How about:

{% if array[id] is defined %}

Didn't check it though.

Nice idea also. Works, done it multiple times :)

How about:

``` {% array[id] is defined %} ```

Didn't check it though.

{% set myArray = {'Apple', 'Banana', 'Orange'} %}

Doesnt work with that array. My id is value not index.

Oh yes, my bad.. Ahmet wanted in_array, not array_key_exists.. So Wojciech solution wont work in your situation :)

Oh, you're right. So i guess you need to use in_array :)

Use array_flip if you know you have unique values to be able to use "{% array[id] is defined %}".
