on_data_display extra parameters

Questionson_data_display extra parameters
gianluca asked 2 months ago

Hi Abu,

I need to send extra parameters, in addition to $data, to my custom column display function, but my code doesn’t work:

$col[“on_data_display”] = array(“display_field_dl($op_table)”,”App\Http\Controllers\GestCantController”,FALSE);

public function display_field_dl($data,$opertable)

Is there any way to do it?
Thanks

To use callbacks in laravel controller, you need to pass second param as $this.

$e[“on_data_display”] = array(“display_field_dl”,$this,false);

And it only receives $data as function input. You can make $op_table variable as class member and access it inside display_field_dl using $this->op_table.

Hope it help.

Unlike grid on_insert event, in this case I’m not able to handle column on_data_display event.

When I replace:

$col[“on_data_display”] = array(“display_field_dl”,”App\Http\Controllers\GestCantController”,FALSE);

with:

$col[“on_data_display”] = array(“display_field_dl”,$this,FALSE);

I got this error (json_encode_jsfunc):

Object of class App\Http\Controllers\GestCantController could not be converted to string

Ok, i will test it. You can continue using complete class name instead of $this.
