Question

我正在尝试将表单发布到PHP脚本，并且它一直无法将请求验证为POST请求，因此它从PHP脚本退出。 AJAX请求返回成功，但是从数据库返回的数据表明将请求识别为POST失败。我尝试更改内容类型等，但无济于事。

JS：

$(document).ready(function() {

    $("#delete4").on('click', function(e) {
        e.preventDefault();
        var ok = confirm('Are you sure you want to delete this?');
        if (ok == true)
        {
            console.log("true")
            var data = $("#form4").serialize();
            $.ajax({
                     data: data,
                     type: "post",
                     url: "delete_AJAX.php",
                     success: function(data) {
                        console.log("successfully deleted");
                        console.log(data);
                        //$("#div4").remove();
                     },
                     error: function(data) {
                          alert("fail");
                          console.log(data);
                      }
            });
        } else {
            return;
        }
    }); 
});

HTML：

<form type="text" name="form4" id="form4" action="delete_AJAX.php" method="post">
    <div class="aligner">
        <button type="button" class="button_div" name="edit" onclick="send(52)">Edit</button>
        <button type="button" class="button_div" id="delete4">Delete</button>
        <button type="button" class="button_div" name="read" onclick="send2(52, 13)">See</button>
    </div><br>
    <input type="hidden" id="hidden_c4" value="13" name="hidden_c">
    <input type="hidden" id="hidden_bid4" name="hidden_bid" value="52">
</form>

PHP：

require_once("db.php");
if ($_REQUEST['REQUEST_METHOD'] === 'POST')
{

    $bid = $_POST['hidden_bid'];
    echo "passed request";

    $sql = "SELECT * FROM xxx WHERE yyy = $bid";
    $result = mysqli_query($connection, $sql);
    if ($result === false)
    {
        die("f1");
    }
    $resultCheck = mysqli_num_rows($result);
    if (!resultCheck > 0)
    {
        echo "ERROR NO RESULT";
        exit();
    };
    $row = mysqli_fetch_assoc($result);
    $delete_cover = $row['cover'];
    unlink($delete_cover);



    // updating table row
    $sql2 = "DELETE FROM xxx WHERE (yyy=?);";
                $stmt = mysqli_stmt_init($connection);
                if (!mysqli_stmt_prepare($stmt, $sql2))
                {
                    header("Location: ../create.php?error&prepare1111");
                    exit();
                }
                else
                { 
                    $stmt->bind_param("i", $bid);
                    mysqli_stmt_execute($stmt);
                    mysqli_stmt_close($stmt);
                    $connection->close();
                    echo "successfully deleted";
                }

} else {
    echo "FAILURE TO REQUEST";
}

因此，我一直不断出现失败“ FAILURE TO REQUEST”，并且当我删除脚本的任何障碍时，post显示为空，并且变量arent设置。因此，它在“ f1”错误处停止。任何帮助都将是惊人的！谢谢！

Answer 1

您似乎为“ REQUEST_METHOD”使用了错误的全局变量。代替OpenFileDialog使用FileDialog

if( $_POST ) {
    echo 'posted';
    //do some stuff
}

AJAX请求无法被PHP脚本识别为POST
