ThinkPHP calls the common/common.php function and prompts the error function undefined solution, thinkphpcommon.php
This article mainly introduces the solution to the error function undefined when ThinkPHP calls the common/common.php function. For friends who use ThinkPHP for project development, they often encounter such problems after upgrading ThinkPHP. The specific description is as follows:
After upgrading ThinkPHP, I used the latest ThinkPHP 3.2 version and put the common functions in common/common.php. However, when calling the function on a specific page, an error message of function undefined appeared.
After checking the official documents, I found that it turns out that the ThinkPHP3.2 version common.php file has been renamed function.php,
So replaced common.php---> with function.php, and the function call was successful! Problem solved!
I hope the method described in this article will be helpful to everyone in ThinkPHP development.
1. How to name and use the public methods of the common folder in the thinkphp project:
Create a common.php file under the common folder (this is fixed)
->
common. You can customize functions in php files, such as: function aa($str){...}, the function name is arbitrary, and the parameters are arbitrary
->
Regarding how to use it, it is divided into two places, one is the controller (i.e. Action, such as loginAction.class.php), you can directly call the function, such as aa($title); the other is in the template file, which needs to be separated by "|", such as {$title|aa}
->
The most important point is that every time you change the common.php file, you need to delete the ~app.php file under the Temp folder, because common.php is first parsed into the ~app.php file, and then be called again.
2. This is simple, such as class IndexAction extends LoginAction{...}. Note: I usually capitalize the first letter of Action naming. I don’t know if it will work in lowercase. It is recommended to capitalize. The corresponding Model name should also be capitalized. Be more standardized.
common/common.php Just write it directly in this file in the method! You can write your own method! But you need to call the file you wrote when using your method! Also, thinkphp is a single-module entry. Just find their files and reference your files in them! This way you can use it directly in the future! ! ! !

thinkphp基于的mvc分别是指:1、m是model的缩写,表示模型,用于数据处理;2、v是view的缩写,表示视图,由View类和模板文件组成;3、c是controller的缩写,表示控制器,用于逻辑处理。mvc设计模式是一种编程思想,是一种将应用程序的逻辑层和表现层进行分离的方法。

在thinkphp3.2中,可以利用define关闭调试模式,该标签用于变量和常量的定义,将入口文件中定义调试模式设为FALSE即可,语法为“define('APP_DEBUG', false);”;开启调试模式将参数值设置为true即可。

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
