Apr 05, 2023 am 10:31 AM

In the TP5 framework, we usually use the View layer to render the page. In the process of rendering the page, some dynamic data may be needed or some PHP methods need to be called to process some logical operations. So how to embed PHP methods in the View layer of TP5? This article will introduce in detail how to write PHP methods in HTML in TP5.

In TP5, we can embed PHP methods by using "{" and "}" in HTML pages. The specific steps are as follows:

  1. First, define the PHP methods that need to be used in HTML in the controller. For example, we define a method in the controller to get the current system time:
public function getTime(){
    return date("Y-m-d H:i:s");
}
Copy after login
  1. Then, in the HTML file of the View layer, use "{" and "} " to wrap the PHP method that needs to be called. For example, we can embed the PHP method defined above in an HTML page. The code is as follows:
当前系统时间是:{echo $this->getTime();}
Copy after login

In this code, we use the "echo" statement to output the obtained system time to on the page.

  1. Finally, visit the page in the browser and you can see the current system time output in the HTML page.

In addition to the "echo" statement, we can also use other PHP statements and functions to implement more complex logical operations. For example, we can use the "if" statement to determine whether a certain condition is true:

{if($isLogin == true)}
    <p>欢迎登录</p>
{else}
    <p>请先登录</p>
{/if}
Copy after login

In this code, we determine whether the user has logged in. If so, the text "Welcome to log in" is output. , otherwise the text "Please log in first" will be output.

Summary:

Through the above introduction, we can see that it is very simple to write PHP methods in HTML pages in TP5. We only need to use "{" and "}" to wrap what we need to use The PHP method will do. This method is very flexible to use in the View layer, which can facilitate us to handle some dynamic operations and logical judgments, and improve our development efficiency.
