使用json数据的bootgrid无法加载php mysqli

Question

我试图将数据与两个按钮的编辑和删除一起加载到bootgrid中。但是没有加载数据。到目前为止，我尝试了以下代码。如何使用json get_data.php页面加载数据。可以有人更正该代码吗。我最近3天都在尝试。我无法得到结果

表格

<table id="grid-basic" class="table table-condensed table-hover table-striped">
    <thead>
    <tr>
        <th data-column-id="id" >Project Name</th>
        <th data-column-id="sender">Project Description</th>
        <th data-column-id="received" data-order="desc">Project Client</th>
        <th data-column-id="commands" data-formatter="commands" data-sortable="false">Commands</th>

    </tr>
    </thead>
    <tbody>
    </tbody>
</table>
</div>

JQuery

 <script>
        var grid = $("#grid-basic").bootgrid({
            ajax: true,
            post: function ()
            {
                return {
                    id: "b0df282a-0d67-40e5-8558-c9e93b7befed"
                };
            },
            url: "get_data.php",
            formatters: {
                "commands": function(column, row)
                {
                    return
                    "<button type=\"button\" class=\"btn btn-xs btn-default command-edit\" data-row-id=\"" + row.id + "\"><span class=\"fa fa-pencil\"></span></button> " +
                    "<button type=\"button\" class=\"btn btn-xs btn-default command-delete\" data-row-id=\"" + row.id + "\"><span class=\"fa fa-trash-o\"></span></button>";
                }
            }
        }).on("loaded.rs.jquery.bootgrid", function()
        {
            /* Executes after data is loaded and rendered */
            grid.find(".command-edit").on("click", function(e)
            {
                alert("You pressed edit on row: " + $(this).data("row-id"));
            }).end().find(".command-delete").on("click", function(e)
            {
                alert("You pressed delete on row: " + $(this).data("row-id"));
            });
        });
    //    $("#grid-basic").bootgrid();
    </script>

get_data.php

  <?php

        $output = $output[] = $output["current"] = 1; $output['rowCount'] = 10;

    }

    echo json_encode( $output );
}
$stmt->close();
