Question

我正在试图弄清楚如何将错误从我的php脚本返回到我的jquery函数。我已经找到了来自this question的最佳答案，其中我回显了一个json对象，我在数据对象中返回但我看不到json对象的各个部分。如何从帖子的返回中访问数据json对象？我的控制台始终显示没有数据错误。

$.post("../dist/scripts/submitOrder.php",
    {
        clientID: clientID,
        date: date,
        po: po,
        orderType: orderType,
        orderlines:JSON.stringify(productArray)
    },
    function(data, status){
        console.log("Data: " + data + "\nStatus: " + status);
        if(data.error){
            console.log("BIG ERROR:" + data.error.message);
        } else {
            console.log("no data error");
        }
    })
        .fail(function() {
        console.log("Fail Data: " + data + "\nStatus: " + status);
    });

relavent .php脚本

if ($conn->query($sql) === TRUE) {
    echo "New record created successfully ";
} else {
    $conn->close();
    //echo "Error: " . $sql . "<br>" . $conn->error;
    echo "error!!!";
    echo json_encode(array('error' => array(
    'message' =>  $sql,
    'code' => $conn->error,
    )));
    exit;

}

我的控制台显示了这个

Answer 1

您的PHP脚本输出PHP错误，导致JSON无效。

您可以停止显示错误：

error_reporting(0);

或修正错误。
