Since the company needs quickform combined with the SMARTY development model, I have been working on it in the past few days. Let me share my experience with you. Quickform is a PEAR class library that can quickly generate JS code for form controls and verification forms. You may think this is written by hand. Isn’t it fast to generate JS and HTML? Isn’t it more troublesome to use that one? Indeed, a small number of form controls cannot show the advantages of quickform, but if there are a large number of form controls, such as the backend of OA, the advantages of quickform will be shown. It’s out. Quickform has the characteristics of clear code and easy maintenance. It is very suitable for the development of large and medium-sized projects. What’s more convenient is that it can be easily used in smarty. ^_^ Without further ado, let’s take a look at the code. To understand the installation of PEAR, please refer to: http://hi.baidu.com/wanghaozi/blog/item/81cfb7003f973687e850cd3e.html. Since the quickform used by the company has been improved by itself, the code will be slightly different from what you see online. It is inconvenient to explain the copyright involved here. I will briefly show the core code so that everyone can understand it. For those who are interested Friendsyou can read this HAOHAPPY article:http://www.phpe.net/articles/418.shtml [php] /* *Author: Hui Boss *Page: path .cfg.php *Function: System path setting *Copyright: copy as you like^_^ */ $global['path']['conf'] = $global['path']['root'] .

You may wonder here why the path is so complicated to define and use absolute What about the path? This is recently adapted to the needs of company projects, haha! In fact, this is helpful for deploying large projects. I believe that novices who have never been exposed to quickform or smarty will be confused by this post. Of course, I will only give a brief introduction here. I hope that everyone who is interested can continue to study in depth and finally see the effect: Look at the judgment and enter twice Check whether the passwords are the same: [php] $form->addRule(array('newPwd','newPwd2'),"The passwords entered twice are inconsistent!",'compare','','client' ); [/php] Does the code look concise and clear? Haha, it will be applied to applications combined with XAJAX next. I will continue to share my learning experience with everyone, hehe!
The above introduces how to use smartprinter. Smarty+QUICKFORM is a small demonstration, including how to use smartprinter. I hope it will be helpful to friends who are interested in PHP tutorials.
