Thinkphp, click the button, and then background action processing, how should it be handled? How to respond to this button? , Please answer me greatly. . Response content: thinkphp, click the button, and then background action processing, how should it be handled? How to respond to this button? , Please answer me greatly. . It is more convenient to use a link, let the href of a point to the path where you want to execute the action, and you can put parameters on the url, if it is more complicated, use ajax to request, the principle is the same. Of course, the biggest advantage of ajax is that the page does not jump/refresh The button triggers a request, and then this request is no different from your request to open a web page, so the backend handles it normally. (For this kind of problem, I suggest you post the code and let us know whether you want an ajax request or a page request) Use ajax to request the url of the backend action to perform the operation After success, you can use js to call back the data returned by the backend

Please answer, what is PHP?
PHP is a server-side scripting language php used to create dynamic web pages. You create pages with PHP and HTML. When a visitor opens a web page, the server will process the PHP command, and then send the processing result to the visitor’s browser, just like ASP or ColdFusion. However, unlike ASP or ColdFusion, PHP is cross-platform and open source. PHP can be executed on Windows NT and many different Unix versions, and it can also be compiled as an Apache module, or a CGI binary file php configuration. PHP is especially lightweight and convenient when compiled as the Apache module. It doesn’t have any cumbersome programming overhead, so it can return results quickly, and there is no need to adjust mod_perl to keep the server’s memory image small. In addition to being able to generate the content of your web pages, PHP can also be used to deliver . The PHP code is embedded in the web page, so you don’t have to set up a special development environment or IDE for it php setup . You use markup PHP code (you can also set PHP to use markup in the form of ASP or even use markup). Anything…
