Implementation method of sliding door developed in PHP in WeChat applet

With the continuous development of the mobile Internet, WeChat applet, as a lightweight application, is becoming more and more popular among people. The development technology of small programs has also been continuously improved and upgraded. Today, we will introduce the implementation method of using PHP language to develop sliding doors in WeChat applet.

1. Understanding Sliding Doors

Sliding doors are a common effect in web design and are used to display a variety of information or content. In the implementation of sliding doors, some CSS techniques need to be used, the most basic of which is to use the overflow:hidden attribute to hide the redundant content area, and then achieve the sliding switching effect by changing the position and width.

2. Use PHP to implement sliding doors

1. Preparation

First, you need to create a page in the WeChat applet, which can be set to a view-like structure. Then, use PHP language to write back-end code, encapsulate the content to be displayed into an array, and then convert it into JSON format data through the json_encode() function for the front-end code to read and render.

2. Front-end implementation

To achieve the sliding door effect in a small program, some CSS and JavaScript technologies are required. Introduce wxparse.js and wx.getSystemInfo() methods into the page. In order to achieve the sliding effect, the relevant style attributes need to be set to dynamic attributes, so that the page can be filled according to the width and the sliding effect can be achieved.

Through the above steps, you can complete the implementation of the sliding door developed in PHP in the WeChat applet. If you are not sure about the specific code implementation process, you can refer to the following sample code.

PHP code:

<?php
$articles = array(
    array('title'=>'第一篇文章', 'content'=>'这是第一篇文章的内容'),
    array('title'=>'第二篇文章', 'content'=>'这是第二篇文章的内容'),
    array('title'=>'第三篇文章', 'content'=>'这是第三篇文章的内容'),
);
$json = json_encode($articles);
echo $json;
?>

Front-end code:

<view class="swiper-box">
    <swiper class="swiper-list" current="{{current}}">
        <block wx:for="{{articles}}" wx:key="title">
            <swiper-item class="swiper-item">
                <view class="title">{{item.title}}</view>
                <view class="content">{{item.content}}</view> 
            </swiper-item>
        </block>
    </swiper>
</view>

<import src="../../utils/wxParse/wxParse.wxml"/>    
<template is="wxparse" data="{{wxParseData:articleNodes}}" />

<script>
    const app = getApp()
    const request = require('../../utils/request.js')
    const WxParse = require('../../utils/wxParse/wxParse.js')
    Page({
        data: {
            current: 0,
            articles: []
        },
        onLoad() {
            this.getArticles();
        },
        async getArticles() {
            const res = await request({
                url: `${app.globalData.host}/getArticles.php`
            })
            this.setData({
                articles: res.data
            })
            this.renderContent()
        },
        renderContent() {
            WxParse.wxParse('articleNodes', 'html', this.data.articles[this.data.current]['content'], this, 0);
        }
    })
</script>
<style>
    .swiper-box {
        width: 100%;
        height: 100%;
        margin-top: 10px;
        overflow: hidden;
    }
    .swiper-list {
        height: 100%;
        width: 100%;
        display: flex;
        flex-direction: row;
    }
    .swiper-item {
        flex-shrink: 0;
        height: 100%;
        width: 100%;
        background: #fff;
        box-shadow: 0 3px 6px rgba(0, 0, 0, 0.16);
        padding: 20px 10px;
        box-sizing: border-box;
        display: flex;
        flex-direction: column;
        align-items: center;
        justify-content: center;
    }
    .title {
        font-size: 24rpx;
        font-weight: bold;
        margin-bottom: 20rpx;
    }
    .content {
        font-size: 28rpx;
        color: #666;
        line-height: 38rpx;
        overflow: auto;
        height: 100%;
        width: 100%;
        position: relative;
    }
</style>
