thinkphp analysis of the related solutions to the form token error _php instance

This paper analyzes the relevant solutions of thinkphp form token errors. Share to everyone for your reference, specific as follows:

Today in the use of thinkphp to do the program, used to create data, when the error prompted "form token error", and then a variety of Baidu all kinds of Google, the online solution given the following suggestions

1, Clear cache: Used, I put all the cache under the files are deleted, and will ~app.php and ~runtime.php two files at the same time deleted, but no effect.

2, set the token_on parameter to false: tried, but also not, although not prompt the form token error, but the data added to the database is empty.

3. Add {__notoken__} in the form of template file: added, but the result is also invalid!

Here I began to have no language, is not the thinkphp on my computer? I think it is not, I wrote another add function, the result is normal, this time I began to think, is not my last function write wrong? But after the inspection, yes! Later slowly a file began that view Ah, finally let me find the reason:

In the thinkphp automatically generated folders, there is a folder called "Data", there is a "_fields" folder, which is stored in the various models of the data table in the relevant information, but also as a mapping (my understanding), I carefully examined one, found that There are two files that have only "' _autoinc ' => true," and the others have a lot, similar to:

<?php return
Array (
 0 => ' id ',
 1 => ' title ',
 2 => ' content ',
 3 => ' Publishedtime ', C6/>4 => ' userid ',
 5 => ' params ',
 ' _autoinc ' => true,
 ' _pk ' => ' id ',
);
? >

By this time, you'll know why. is an operation of these data to delete a part, so that thinkphp in the form verification, the data can not be mapped, also led to the thinkphp error, will they in accordance with the order of the data table added, rerun, normal!

To this, the problem solved ~ ~ ~ ~
