jQuery Grid Plugin - jqGrid

 Hi

I would to like to send all rows from the table jqgrid for PHP. My code is here:

$("#cadastrarDemanda").click(function(){

   alert("I went!!!");

   var gridData = jQuery("#tabelaAC").getRowData();

   var postData = JSON.stringify(gridData);

   alert("JSON serialized jqGrid data:n" + postData);

   $.ajax({

             type: "post",

             url: "IncluirAreaECompetencia.php",

             data : { jqGrid: postData}

             dataType: "json",

             contentType: "application/json; charset=utf-8″

             success:function(response, textStatus, xhr){

                   alert("Sucess");

             },

             error:function(xhr, textStatus, errorThrown){

                   alert("Error");

             }

   });

});

The postadata variable has rows in json format:
[{"idLinha":"1","codAreaGrid":"2.06.04.009","areaConhecimentoGrid":"Anatomia",

"codCompetenciaGrid":"212","competenciaGrid":"Anatomia Animal"},
 {"idLinha":"2","codAreaGrid":"2.06.04.009","areaConhecimentoGrid":"Anatomia",

"codCompetenciaGrid":"211","competenciaGrid":"Anatomia Humana"}]

How can I send the rows of jqgrid table for IncluirAreaECompetencia.php file?

I have tried using the post, get and request variables, but it doesn't woks….

The example: $segments = $_REQUEST['jqGrid'];

Please, if anyone can help me…
