一种形式的PHP中的两种形式的动作

Question

I have two problems with my php code. 我的PHP代码有两个问题。

First one is how variable 第一个是可变的

$linkorig

can see after 可以看到

$_POST['formsubmitted']

,when i get it from redirected page? ，当我从重定向页面得到它时？

Second question is how can do form submit with different action, after all error checking ? 第二个问题是，在进行完错误检查之后，表单如何才能以不同的方式提交？

Maybe possible with some javascript or php code. 可能有一些javascript或php代码。

<?php
    $linkorig=$_POST['link-orig']; // get destination link from redirected page , for excample http://mikrotik.lv -- works fine 
    if (isset($_POST['formsubmitted'])) 
    {
        // script try login with credentials  with  <form action="login.php"   --- works fine
        //Error checking !
        if (empty($error)) //if not found any errors {
            // login with credentials and same form but  with  <form action="other_login.php"   --- i dont know how to do :(
        }
    }
?>

You can easily use one form for 2 actions : 您可以轻松地将一种形式用于2个操作：

<form method='post' action='post.php'>
<input type='text' name='field1' />
<input type='text' name='field1' />

<button name='action1'>action1</button>
<button name='action2'>action2</button>
</form>

On the page post.php : 在页面post.php ：

All your variable will be in $_POST , namely $_POST['field1'], $_POST['field2'], $_POST['action1'] and $_POST['action2'] Use a simple condition : 您所有的变量都将在$_POST ，即$_POST['field1'], $_POST['field2'], $_POST['action1'] and $_POST['action2']使用一个简单的条件：

if(isset($_POST['action1'])) {
  //some code here but still check action2

  // edit : you can call the action2 with jquery and [ajax][1]
  // you can use header('location: http://example.com?field1='.$_POST['field1'].'&field2='.$_POST['field1']) to redirect, but no output before using header => see ob_get_clean() if you have any problem.
}
else { exit; } //stop it all if action1 failed

However, if you redirect your page, you have no longer $_POST variable. 但是，如果您重定向页面，则不再有$ _POST变量。 You can use /page.php?var1=... and $_GET them the same as you would do with $_POST. 您可以使用/page.php?var1=...和$ _GET它们，就像使用$ _POST一样。
