Question

我有2个表格。一个提交只是一个提交/添加，第二个是选择/重定向。现在两者都重定向。如何防止顶部提交重定向？

<?php
if($_POST){

        //store as session variable
        $_SESSION['id'] = $_POST['bolredir'];
        //forward browser
        die(header("Location: add-job.php"));
}
?>


<!DOCTYPE html>

        <body>
       <div class="">
                <form name="addcust" method="post" action="index.php">
                        <label> Name:</label>
                        <input type="text" id="cust_name" name="cust_name"/> <br />
                        <input type ="submit" name="addcust" value="Submit" /> <br /> <br />
                </form>
        </div>

   <?php

 try
     {
     $conn = new PDO("mysql:host=localhost;dbname=$dbname", $username, $password);
     $stmt = $conn->prepare("SELECT * FROM customer");
     $stmt->execute();

     $result = $stmt->fetchAll();
 ?>
 <form action="<?= $_SERVER['PHP_SELF']; ?>" method="POST">
 <select name="bolredir">
 <option></option>
 <?php
     foreach ($result as $row)
         {
         echo "<option value=\"{$row['id']}\">{$row['cust_name']}</option>";
        //$_SESSION['id'] = $row['cust_name'];
         }
     }
 ?>
 </select>
  <input type="submit" name="Submit" value="Submit" />
 </form>

 </body>

 </html>

Answer 1

您可以在表单提交上返回false。给第二个表单一个名称，例如“dontsubmit”，然后阻止它提交并导致表单重定向。

document.forms["dontsubmit"].onsubmit = function(){
   return false;
}

Answer 2

如果您不想通过邮寄或获取提交表单，请尝试此操作。并希望以另一种方式提交

 <form action="<?= $_SERVER['PHP_SELF']; ?>" method="POST" onsubmit="return false;">

Answer 3

给第二个表单提交一个不同的名称

<input type="submit" name="SubmitForRedirect" value="Submit" />

现在在你的php中使用这段代码

if(isset($_POST['SubmitForRedirect'])) {
    //store as session variable
    $_SESSION['id'] = $_POST['bolredir'];
    //forward browser
    die(header("Location: add-job.php"));
}

您也可以将第二种形式直接重定向到add-job.php

将<?= $_SERVER['PHP_SELF']; ?>替换为add-job.php

<form action="add-job.php" method="POST">

如何停止重定向？
