The example of this article describes the Create method and token verification in thinkphp. Share to everyone for your reference, specific as follows:

Thinkphp's Create method and token authentication are mainly related to the security of the form.

The code is as follows:

<?php
//This class is automatically generated by the system, only for test purposes 
class Indexaction extends action{public
 function Index () {
  $this-> Display ();
 }
 General users in the site to complete the information added modification ... But there was a surprise that the user's Web page was saved as local, and then a lot of the data was simulated in this, and then ... Keep refreshing to write in my database, also the hidden table in the ID to change
 //Originally in the process can be judged superior source, if the superior address is equal to the address of my site, I will write it, if not my site, I will prohibit its writing ... The superior source can be simulated
 //create () automatically to obtain relevant data; Automatic token verification; Complete automatic mapping, AutoFill, automatic verification (three automatic) Creation success returns an array, or false; Adds a hidden item hidden item encryption method MD5
 // Token authentication can be set, and encryption methods can also be set token_no=>true;
 function Add () {
  $user =new Model (' user ');
  if ($vo = $user->create ()) {
   //success This method is a method of success, it will give the corresponding jump page, jump time, as well as the success of information prompts, this file in the default public common file
   //dump ($VO);
   echo $user->username;
   echo $user->password;
   Dump ($user);
   $this->success (' instantiation model succeeded ');
  }
  else{
   //error is the way to fail, in which the execution failure code does not go backwards
   $this->error ($user->geterror ());//geterror () Specifically used to display verbose error messages
  }}
?>

The template file is as follows:

<form action= "__url__/add" method= "POST" >
<input type= "text" name= "username"/> <input "type="
Password "name=" password "/> <input type=" hidden "
id=" 2 "/> <input type=" Submit "value="
