I can't use Events on Laravel5.5.

$e["on_insert"] = array("add_kamoku", null, FALSE);

error messeage.

call_user_func() expects parameter 1 to be a valid callback, function 'add_kamoku' not found or invalid function name

It appears that your function add_kamoku is some class method and not global function.
In that case, you need to pass class name as second param. e.g. if your class name is 'Foo' you need to set:

$e["on_insert"] = array("add_kamoku", "Foo", FALSE);

Thank you.

It solved. A little problem remains.

'jqg'+xx(xx is integer) show in Id column(Primary/autoincrement).
When reloading, It change integer.

You can set:

$opt["reloadedit"] = true;


It will force reloading after add/edit.

Unfortunately it doesn't work.
My options is follow



protected function opt_edit($param) {

$opt["cellEdit"] = true;
$opt["scroll"] = true;
$opt["autowidth"] = true;
$opt["resizable"] = true;
$opt["viewrecords"] = true;
$opt["caption"] = $param;
$opt["actionicon"] = TRUE;
$opt["reloadedit"] = true;
// $opt["toolbar"] = TRUE;
// $opt["toppager"] = TRUE;
return $opt;

Hi Abu,

I need to handle on_insert event in a subgrid (laravel) so I add in my public function index_detail(Request $request) following code:

$e[“on_insert”] = array(“add_prestazione”, “App\Http\Controllers\OrdiniController”, true);


In the same controller I put my custom code with a test query:

public function add_prestazione($input)
global $grid;
$grid->execute_query(“INSERT INTO test VALUES (‘2′,’testo’)”);


but I got this error message in chrome console.

  1. {message: “Call to a member function execute_query() on null”, exception: “Error”,…}
    1. exceptionError
    2. fileC:\xampp\htdocs\sigesc\app\Http\Controllers\OrdiniController.php
    3. line2169
    4. messageCall to a member function execute_query() on null

        5. type->
      3. 2{function: “indexDetail”, class: “App\Http\Controllers\OrdiniController”, type: “->”}
        1. classApp\Http\Controllers\OrdiniController
        2. functionindexDetail
        3. type->

Can you help me find where I’m wrong?

When you use laravel, inside controller there is no $grid variable which is defined globally. You need to make it controller member variable and access with $this->grid;

Refer this code:
