Ignited datatables, how to use callback function?

Question

I am using Ignited datatables (for codeigniter) and I'm using the server side. I would like to show some values in RED or GREEN depending on their values.

This is how I call the function inside the edit_column:

->edit_column('releve_statut', '$1', $this->label_this('releve_statut'))

And this is the function I'm calling:

public function label_this($str) {

    if($str == "Réalisé"){
        $r =  label_badge('success', 'Réalisé'); 
    } else if ($str == "En cours"){
       $r = label_badge('warning', 'En cours'); 
    }

    return $r;

}

Any suggestion?

Thanks :)

Could I ask what does the label_badge function does, I'm tempted to put in a CSS solution but I don't really understand what markup that label_badge function creates, and where is it used — EdL

It's for formating the text. It creates a colored badge. function label_badge($type, $text){ return '<span class="badge bg-'.$type.'">'.$text.'</span>'; } The problem is that the comparison inside my function label_this doesn't work :/ — oussama.tn

When I add a third else, it shows the value inside it: else { $r = 'Error'; } — oussama.tn

If you want to use a callback on server side, an easy and painless solution is creating a Codeigniter Helper class.

So, in your code, change the third parameter of edit_column:

->edit_column('releve_statut', '$1', 'label_this(releve_statut)')

Finally, define the function label_this($str) in a helper class. Don't forget to load it before calling $this->datatables->generate().

->edit_column('releve_statut', '$1', 'callback_label_this(releve_statut)');

Not an expert on this but I know this is how its done elsewhere in codeigniter so although I can't test, makes sense that this should work

Original (still sort of relevant) What you need to do here is have a CSS style sheet as so

.bg-success{
    color: green;
}
.bg-warning{
    color: red;
}

this will style the text as coloured If you want a coloured background then replace color with background color.

The problem is that the comparison doesn't work. When I do this: if($str == "Réalisé"){ $r = 'AAA'; } else if ($str == "En cours"){ $r = 'BBB'; } else { $r = 'Error'; } The result is: 'Errror'! PS: The values in the database are: enum('','En cours','Réalisé').

I have edited it now so I think this is what it should be like

Thanks for the answer but it's still not working :/ when i put your code it shows this value inside my table: callback_label_this(releve_statut)

The callback function on the server side didn't work for me :/

The solution that I did is to add fnDrawCallback to the datatables initialisation (client side) which is is called on every 'draw' event.

"fnDrawCallback": function( oSettings ) {
                        var $green = $('.statut-style').filter(function() {
                                    return  ($(this).text() == 'Réalisé');
                                });
                        // Set the green elements to color green
                        $green.addClass("badge bg-success");
      },

If anyone know how to do it on the server side, I'll be glad if you share it ;)

Thanks!
