Hi, I am new to jqgrid and I wanty to filter/search data, but I dont know how to change de php file, I am using this in HTML file

$(“#srccontents”).filterGrid(“list”,{ gridModel:true, gridNames:true, formtype:”vertical”, enableSearch: false, enableClear: false, autosearch: true });

and the query in php file is:

$SQL = “SELECT id, nombre, descripcion FROM desc_examenes ORDER BY $sidx $sord LIMIT $start , $limit”;
