Question

我有从表单获取数据的查询，当按下提交按钮时，数据应存储在数据库中。当表单的操作是 action =＆＃34;＃＆＃34; 时，数据被输入到数据库中。但是当操作是 action =＆＃34; otherPage.php＆＃34; 时，数据不会插入到数据库中。有帮助吗？

备注：我知道需要将查询更改为反对SQL注入，这仅用于测试

代码：

if(isset($_POST['submit']))
            {
                $name = $_POST['fullName'];

                $idNumber = $_POST['idNo'];
                $cardNo = $_POST['cardNo'];

                $_SESSION['fullName'] = $name;
                $_SESSION['id'] = $idNumber;

                $checkExists = "SELECT * FROM system.table WHERE idNumber = '$idNumber' ";
                $resExists = mysqli_query($connection,$checkExists)
                    or die("Error in query: ". mysqli_error($connection));

                if(mysqli_fetch_assoc($resExists) > 0)
                {
                    $updateCard = "UPDATE system.table SET cardNo = '$cardNo' WHERE idNumber=$idNumber"; 

                    $resUpdate= mysqli_query($connection,$updateCard)
                    or die("Error in query: ". mysqli_error($connection));
                }

                if(mysqli_fetch_assoc($resExists) < 1)
                {
                    $company = $_POST['company'];
                    $name = trim($name);
                    $last_name = (strpos($name, ' ') === false) ? '' : preg_replace('#.*\s([\w-]*)$#', '$1', $name);
                    $first_name = trim(preg_replace('#'.$last_name.'#', '', $name));  

                    $insert = "INSERT INTO system.table (idNumber,name,surname,company,cardNo) VALUES 
                        ('$idNumber','$first_name','$last_name','$company','$cardNo')";

                    $resInsert = mysqli_query($connection,$insert)
                    or die("Error in query: ". mysqli_error($connection));
                }



                $connection->close();
            }

我不知道这是否是解决问题的方法，但它确实有效。我在代码的开头添加了ob_start();，将操作保留为

<form role="form" method="POST" action="#">

然后包括

header('Location:otherPage.php');

以便页面自动重定向到 otherPage.php

如果您在同一文件夹中有两个文件，它应该正常工作：

MyFolder文件 - testForm.php - testUpload.php

testForm.php：

<!DOCTYPE html>
<html>
<head>
</head>
<body>
<form method="post" action="testUpload.php">
    <fieldset>
    <legend>Form</legend>   
        <label>Name: </label>
        <input type="text" name="name">
        <input type="submit">
    </fieldset>
</form>
</body>
</html>

testUpload.php：

<?php
print($_POST['name']);
exit;

您的Web服务器配置中是否有任何重定向语句（例如Apache httpd.conf）？

当表单操作是同一页面时，查询工作，而不是重定向到另一页面时
