An information management system was built using the bootstrap CMS template system. Learn the workflow of dynamic Web Access through this system.Grab packet analyze the data request flow for a page as shown:Similarly, for the need to insert data into the database, you can use the Ajax interface to send parameters to the PHP background, PHP script after parsing th

Using function recursion to implement dynamic tree menus based on php and MySQL Tree menus are widely used in many desktop application systems. The main advantage of tree menus is that the structure is clear, which helps users know their location clearly. However, the application of tree menus on the web can be directly used without an ideal ready-made component.

found that this kind of tree menu can be implemented through recursive functions, so that the display of tree menus can be dynamically changed without the limit of series. The following is the processing code of a dynamic tree menu written in php, MySQL, and JavaScript. if you are interested, let's take a look at how I implement it with me :) First, we need a d
