CI framework WeChat development - custom menu, ci framework custom menu

Implemented the custom menu function under the CI framework. Wrote a model and a class library. By the way Comes with access_token implementation 

<?<span>php

The above is the content in the library, which mainly generates the json string of the menu based on the data table

The above are various methods in the model.

The table structure of the database is as follows, with statements for creating tables.

The following is the method of obtaining token written under system/core/common.php. In fact, it needs to be salted, otherwise disgusting people will do disgusting things.

<span>function</span><span> get_access_token(){

        <span>$old_filename</span> = APPPATH."cache/".<span>md5</span>(<span>date</span>("YmdH",<span>time</span>()-3600)).".php"<span>;

I won’t write about the previous menu management, it’s just to manage the data in that table and make sure that there is no problem with the data in the data table.

Only need

in the controller

$this->load->library("Makemenu");

Then call $this->makemenu->dolist();

will be pushed to the WeChat server. You also need to pay attention to defining two constants APPID and APPSECRET in the entry file.

I released it for everyone, I hope it will be useful, and I will make a backup copy for myself.
