When working on a project, for example, a B2B person jumps from the mall to the backend of the seller center. When he has both a member account and a seller, and lets him log in to the mall, there is no need for the seller to log in. During the processing, Use form to log in automatically. This article mainly brings you an example of form automatic submission. The editor thinks it is quite good, so I will share it with you now and give it as a reference for everyone. Let’s follow the editor to take a look, I hope it can help everyone.

Simple idea: you can log in as an ordinary member. If you log in successfully, you can save your login name, password, and user ID. For security, you can encrypt it with AES (detailed introduction in the previous article) and store it in cookies. On the page, you need to go to the seller center, where you can determine the cookie that was initially saved and whether it is a seller. If so, use the form to automatically log him in.

Case implemented on ecshop:

Create a lib_stm_form.php under includes:

class form{
  public function hform($username,$password){
    $str = &#39;<body><form action="privilege.php" method="post" id="qqform" name="qqform" style="display:none"> &#39; ;
    $str .= &#39;账号:<input type="text" name="username" value="&#39; . $username . &#39;" /><br />&#39; ;
    $str .= &#39;密码：<input type="text" name="password" value="&#39; . $password . &#39;" /><br />&#39; ;
    $str .=&#39;<input type="hidden" name="act" value="signin" /></form></body>&#39;;
    $str .= &#39;<script>window.onload= function(){document.getElementById("qqform").submit();}</script>&#39;;
    echo $str; exit;
  }
}
?>

Copy after login

In the signin method of privilege.php, perform aes decryption and introduce lib_stm_form.php::

require_once(ROOT_PATH . &#39;includes/lib_smt_from.php&#39;);
$form   = new form();
$username = $j_token[&#39;username&#39;];
$password   =$j_token[&#39;password&#39;];
$a = $form->hform($username,$password);
exit;

Copy after login

This is achieved. The form is automatically submitted for login. If you are a member or seller, you can log in once.
