Question

I have a table named state with columns state_id, state_name. Currently I can add new states and edit them, but I can’t delete states. What might be wrong with my code?

{title:"Actions",template:'<a class="left" onclick="javascript:openEditStatePopup(this);">Edit</a>' + 
    '<a class="right" onclick="javascript:deleteState(this);">Delete</a>'
    ,width:120,sortable:false}

This snippet is the view code, and when I click the link, it executes the following JavaScript:

function deleteState(element)
{
    var countryDetail = {};
    var GriddataItem = $("#state_grid").data("kendoGrid").dataItem($(element).closest("tr"));
    countryDetail.state_id =GriddataItem.state_id;
    countryDetail.state_name = GriddataItem.state_name;
    // alert(countryDetail.state_id);
    $.ajax({
        url:"<?= $this->baseUrl('admin/state/delete')?>",
        data: {state_id :  countryDetail.state_id},
        dataType: "json",
        type: "POST",
        success: function(){
            alert('success');
        },
        failure:function(){
            alert('not working');
        }
    });
}

When I echo alert(countryDetail.state_id) before the $.ajax call, I can get the correct state id.

My delete controller is:

public function deleteAction()
{

    $state = $this->_request->_getPost('state_id');
    $stateMapper = new Application_Model_Mapper_StateMapper();
    $stateMapper->delete($state);
}

and the model mapper for deleting is:

public function delete(Application_Model_State $state)
{
    $data = $state->toArray();
    $adapter = $this->getDbTable()->getAdapter()->delete(array('state_id=?'=>$data['state_id']));
}

Hi you need to write deleteAction as following

public function deleteAction()
{


    $state = $this->_getParam('state_id');
    $stateMapper = new Application_Model_Mapper_StateMapper();
    $stateId = $stateMapper->delete($state);
    $this->_helper->json(array('success'=>1));
}
