Question

我试图用jQuery ajax发布数据，但是它只将一半的数据发布到下一页。

我可以看到所有数据都被发送到chrome开发人员工具中的下一页，但是其发送到的页面的响应不成功。

这是我的JS代码：

    var id = $(this).parents('tr').attr('data-id');
        var time = $('#time').val();
        var mon = $('#mon').val();
        var tue = $('#tue').val();
        var wed = $('#wed').val();
        var thu = $('#thu').val();
        var fri = $('#fri').val();
        var sat = $('#sat').val();

    $.ajax({
        type: "POST",
        url: "update.php",
        data: {
             "id": id,
             "time": time,
             "mon": mon,
             "tue": tue,
             "wed": wed,
             "thu": thu,
             "fri": fri,
             "sat": sat
        },
        dataType: "json",
        success: function(response)
        {
            if(!response.error) {
                console.log(response.msg);
            } else {
                console.log(response.msg);
            }
        }
    });

和update.php代码：

if ( isset($_POST) ) {

    if( isset($_POST['id'] ) && $_POST['id'] > 0 && !$error) {
        $id = $_POST['id'];
        $error = false;
    } else {
        $error = true;
    }

    if( isset($_POST['time'] ) && $_POST['time'] > 0 && !$error) {
        $time = $_POST['time'];
        $error = false;
    } else {
        $error = true;
    }

    if( isset($_POST['mon'] ) && $_POST['mon'] > 0 && !$error) {
        $mon = $_POST['mon'];
        $error = false;
    } else {
        $error = true;
    }

    if( isset($_POST['tue'] ) && $_POST['tue'] > 0 && !$error) {
        $tue = $_POST['tue'];
        $error = false;
    } else {
        $error = true;
    }

    if( isset($_POST['wed'] ) && $_POST['wed'] > 0 && !$error) {
        $wed = $_POST['wed'];
        $error = false;
    } else {
        $error = true;
    }

    if( isset($_POST['thu'] ) && $_POST['thu'] > 0 && !$error) {
        $thu = $_POST['thu'];
        $error = false;
    } else {
        $error = true;
    }

    if( isset($_POST['fri'] ) && $_POST['fri'] > 0 && !$error) {
        $fri = $_POST['fri'];
        $error = false;
    } else {
        $error = true;
    }

    if( isset($_POST['sat'] ) && $_POST['sat'] > 0 && !$error) {
        $sat = $_POST['sat'];
        $error = false;
    } else {
        $error = true;
    }

    if( !$error ) {
        $query = "UPDATE table
                  SET time      = '$time',
                      monday    = '$mon',
                      tuesday   = '$tue',
                      wednesday = '$wed',
                      thursday  = '$thu',
                      friday    = '$fri',
                      saturday  = '$sat'
                  WHERE scheduleID = '$id'";

        $result = mysqli_query($conn, $query) or die("database error:". 
mysqli_error($conn));
        $msg = array('error' => $error, 'msg' => 'Success! updation in mysql');
    } else {
        $msg = array('error' => $error, 'msg' => 'Failed! updation in mysql');
    }
}

echo json_encode($msg);

和html（使用Metronic管理主题中的可编辑表格）

<div class="table-toolbar">
<div class="row">
    <div class="col-md-12">
        <div class="btn-group">
            <button id="sample_editable_1_new" class="btn green"> Add New
                <i class="fa fa-plus"></i>
            </button>
        </div>
    </div>
</div>
</div>
<table class="table table-striped table-hover table-bordered" id="sample_editable_1">
<thead>
    <tr>
        <th>Time</th>
        <th>Monday</th>
        <th>Tuesday</th>
        <th>Wednesday</th>
        <th>Thursday</th>
        <th>Friday</th>
        <th>Saturday</th>
        <th>Edit</th>
        <th>Delete</th>
    </tr>
</thead>
<tbody>
    <tr data-id="5">
        <td class="time">05:30</td>
        <td class="mon">Program Name</td>
        <td class="tue">Program Name</td>
        <td class="wed">Program Name</td>
        <td class="thu">Program Name</td>
        <td class="fri">Program Name</td>
        <td class="sat"></td>
        <td>
            <a class="edit" href="javascript:;"> Edit </a>
        </td>
        <td>
            <a class="delete" href="javascript:;"> Delete </a>
        </td>
    </tr>
</tbody>

只有＆＃34; id＆＃34;而且＆＃34;时间＆＃34;在update.php文件中收到。

我尝试过添加contentType和JSON stringify但是在update.php没有收到任何数据。

我做错了什么？任何帮助将不胜感激。谢谢！

Answer 1

P Parsons，你能提供代码的html模板吗？我认为在分配值时，mon，tue，wed可能是空的。也许id为#mon，＃tue ... #sun的元素没有'value property。'

您也可以尝试

<?php 

if ( isset($_POST) ) {

    extract($_POST);

    if ( !isset($id) || empty($id) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [id]'));exit;
    }

    if ( !isset($time) || empty($time) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [time]'));exit;
    }

    if ( !isset($mon) || empty($mon) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [mon]'));exit;
    }

    if ( !isset($tue) || empty($tue) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [tue]'));exit;
    }

    if ( !isset($wed) || empty($wed) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [wed]'));exit;
    }

    if ( !isset($thu) || empty($thu) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [thu]'));exit;
    }

    if ( !isset($fri) || empty($fri) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [fri]'));exit;
    }

    if ( !isset($sat) || empty($sat) ) {
        echo json_encode(array('error' => true, 'msg' => 'missing [sat]'));exit;
    }

    $query = "UPDATE table
              SET time      = '$time',
                  monday    = '$mon',
                  tuesday   = '$tue',
                  wednesday = '$wed',
                  thursday  = '$thu',
                  friday    = '$fri',
                  saturday  = '$sat'
              WHERE scheduleID = '$id'";

    $result = mysqli_query($conn, $query) or die("database error:". mysqli_error($conn));

    echo json_encode(array('error' => false, 'msg' => 'Update success'));exit;
}else{
    echo json_encode(array('error' => true, 'msg' => 'missing [POST]data'));exit;
}

?>

...在提交数据后捕获确切的错误。

正如 tima_t 已经说过，请检查 #mon ， #tue ...输入的值。

Ajax只发布了一半的数据
