How to implement the drawer menu function in WeChat applet with PHP

With the popularity of smartphones and the emergence of WeChat applets, drawer menus have become a common UI design. This design can provide a better user experience and make the interface simpler.

In this article, we will introduce how PHP implements the drawer menu function in WeChat applet. In this article, we will use WeChat applet and PHP as examples.

1. Create a page for the WeChat applet

First, we need to create a page containing a menu in the WeChat applet. In this page, we will use the component and the and instructions provided by the WeChat applet.

<!-- 菜单内容 -->

< ;/view>

<image class="menu-image" src="{{showMenu? '/images/close.png':'/images/menu.png'}}"></image>

In this code snippet, we have created a container view and a button view where if the user clicks on the button, the toggleMenu function is triggered. In the toggleMenu function, we will use the showMenu variable to determine whether the menu is displayed. If the menu is shown, we will hide it and change the image of the button; if the menu is hidden, we will show it.

2. Create PHP backend code

In this step, we need to create a PHP script to get the menu data and return it to the applet page.

Assume that our menu data is stored in a file named menu.php and is output in JSON format. Below is an example of a PHP script that can get menu data and return it.

header('Content-type: application/json');
$menu = file_get_contents('menu.php');
echo $menu;
?>

In this example, we first define the header of "Content-type: application/json", which means that we will return data in JSON format. Next, we use the "file_get_contents" function to read the data in the "menu.php" file. Finally, we return the data to the mini program page through the "echo" function.

3. Render data into the mini program page

The last step is to render the menu data into the mini program page. We can use the component and the directive provided by the mini program to implement this process.

    <navigator url='{{item.url}}'>
        <text class='menu-item'>
          {{item.text}}
        </text>
    </navigator>
</block>

In this code snippet, we use the component and the directive to iterate over each item in the menu array and render them one by one. Link. When users click the link, they will visit the URL specified in the menu.

Summary

In this article, we introduced how PHP implements the drawer menu function in WeChat applet. We first created an applet page containing a menu, and then created a PHP script to get the menu data and return it to the applet page. Finally, we use the component and the directive provided by the mini program to render the menu data into the mini program.
