Call to undefined function in Laravel 4

I have set up a resource in Laravel 4 for an entity "Artists"; Within the ArtistController, I have added a function of my own, youtube_embed. When I call this function in my view (the show view), it is saying that it is undeclared. Do you have any idea why I am receiving this error? Thank you.

Here is the code:

in ArtistController:

 public function youtube_embed($vari) {

        $step1=explode('v=', $vari);
        $step2 =explode('&',$step1[1]);
        $iframe ='<iframe style="border:4px solid #41759d" width="460" height="259" src="http://www.youtube.com/embed/'.$step1[1].'" frameborder="0" allowfullscreen></iframe>';

        return $iframe;

    }

in the show.blade.php:

{{youtube_embed($artist->video_path);}}

Thank you again for your help.

There's lot of way to achieve this.

  • You could include the file at the bottom of app/start/global.php

  • You could make a helpers class

    1. Create a folder in app called "helpers" along with a file called Embed.php
    2. add "app/helpers" to composer.json in the "autoload.classmap" section. Watch out for commas.
    3. In app/start/global.php, add app_path().'/helpers' in the ClassLoader::addDirectories array. This step is not necessary but it prevents you from doing composer dump-autoload everytime you add a new helper.

    4. in app/helpers/Embed.php, you could do something like this

      class Embed {
  public static function youtube($vari) {

    $step1 = explode('v=', $vari);
    $step2 = explode('&amp;', $step1[1]);
    $iframe = '<iframe style="border:4px solid #41759d" width="460" height="259" src="http://www.youtube.com/embed/'.$step1[1].'" frameborder="0" allowfullscreen></iframe>';

    return $iframe;
  }
}

    And use it in blade like this

    {{Embed::youtube($artist->video_path)}}

    That way, if you want to add embed vimeo, you could also add it and call it like 

    {{Embed::vimeo($artist->video_path)}}

  • You could make a custom form macro

    Form::macro('youtube', function($vari) {
   $step1 = explode('v=', $vari);
   $step2 = explode('&amp;', $step1[1]);
   $iframe = '<iframe style="border:4px solid #41759d" width="460" height="259" src="http://www.youtube.com/embed/'.$step1[1].'" frameborder="0" allowfullscreen></iframe>';

    return $iframe;
});

    and call it like this

    {{ Form::youtube($artist->video_path) }}

So many possibilities! :)

Looks like all you need is just a helper. I would do this in my app.

Firstly, create a folder "helpers" in your "app" folder.

Then create a file named "common.php" inside the "helpers" folder. Put your function in this file:

    <?php

        if ( ! function_exists('image'))
        {
            function youtube_embed($vari)
            {
                 $step1=explode('v=', $vari);
                         $step2 =explode('&amp;',$step1[1]);
                         $iframe ='<iframe style="border:4px solid #41759d" width="460" height="259" src="http://www.youtube.com/embed/'.$step1[1].'" frameborder="0" allowfullscreen></iframe>';

                         return $iframe;
            }
         }

Next, include this file in your route.php.

  <?php

      include('libraries/common.php');

And you can use your function inside your application.
