either you are not adding the $cols array or you are not displaying data in sql command

Is the $cols-Array required ? It doesn't look like this in the "getting started" docs … i dont add it … that should be the point then …. I'll give it a try ….

Jan Rothe answered 7 years ago

I'll gave it a shot, and no data anyway ….

this is what i added to my file:
$col = array();
$col["title"] = "ID";
$col["name"] = "id";
$col["width"] = "10";
$cols[] = $col;
$col = array();
$col["title"] = "User";
$col["name"] = "uid";
$col["width"] = "10";
$cols[] = $col;

And in chromedevtools this is the JSON-Response

{"page":"1","total":3,"records":"52","rows":[{"id":"1","uid":"1"},{"id":"2","uid":"2"},{"id":"3","uid":"3"},{"id":"5","uid":"5"},{"id":"6","uid":"6"},{"id":"7","uid":"7"},{"id":"8","uid":"53"},{"id":"9","uid":"9"},{"id":"10","uid":"10"},{"id":"11","uid":"11"},{"id":"12","uid":"12"},{"id":"13","uid":"13"},{"id":"14","uid":"14"},{"id":"15","uid":"15"},{"id":"16","uid":"16"},{"id":"17","uid":"17"},{"id":"19","uid":"19"},{"id":"21","uid":"21"},{"id":"22","uid":"22"},{"id":"23","uid":"23"}]}

but i dont get any data in the grid ….

Hello,

This error usually occur when you have some html code printed before $grid->render() function call, that causes invalid format of json data.

Please recheck OR post the code at [email protected]

Thanks
