基于PHP表单重定向的下拉选择 [英] PHP Form Redirect Based Off of Drop Down Selection

问题描述

这涉及到我曾询问过的一个问题。填写完表格后，我想确定在填写表单时通过选择的下拉列表提交表单后，它将转到哪个页面。

例如，你输入：

你的名字

电子邮件

电话号码

然后从下拉菜单中选择第3页。提交。

然后我需要它将您重定向到Page 3，因为这是您在下拉菜单中选择的那个。我知道这应该很简单，我似乎无法弄清楚如何去做。

解决方案

在表单提交的脚本中：

  if（$ _POST ['dropdown-name'] =='Page 3'）{
 header（Location：page3.php）; 
 header其他if（$ _POST ['dropdown-name'] ==''Page 4'）{
 header（Location：page4.php）; 
} // ... etc 
  

〜

  $ pages = array（'Page 1'=>'page1.php'，'Page 2'=>'page2.php'，'Page 3' =>'page3.php'）; 
 $ b $ if（array_key_exists（$ _ POST ['dropdown-name']，$ pages））{
 header（Location：。$ pages [$ _ POST ['dropdown-name']] ]）; 
} else {
 echoError processing form; //提交的表单值不在你的数组中，也许是一个黑客攻击尝试
} 
  

This relates to a previous question I had asked about filling out a php form and using those answers to populate a page. When finished filling out the form, I want to determine what page it goes to after you submit the form by a dropdown you choose while filling out the form.

For example, you type in:

Your Name

Email

Phone Number

Then from a drop down you'd pick "Page 3".

Then hit submit.

I would need it then to redirect you to "Page 3" because that's the one you chose in the drop down. I know this should be simple, I just can't seem to figure out how to do it. Thank you in advance to all that help!

解决方案

In the script your form submits to:

if ($_POST['dropdown-name'] == 'Page 3') {
    header("Location: page3.php");
} else if ($_POST['dropdown-name'] == 'Page 4') {
    header("Location: page4.php");
} // ... etc

~

$pages = array('Page 1' => 'page1.php', 'Page 2' => 'page2.php', 'Page 3' => 'page3.php');

if (array_key_exists($_POST['dropdown-name'], $pages)) {
    header("Location: " . $pages[$_POST['dropdown-name']]);
} else {
    echo "Error processing form"; // submitted form value wasn't in your array, perhaps a hack attempt
}
