How to use PHP to implement icon arrangement in WeChat mini-programs

As an increasingly popular mobile application, WeChat mini program provides users with many convenient services. Among them, icon arrangement is an important part of the mini program interface. If you need to arrange icons when developing small programs in PHP, this article introduces several implementation methods for your reference.

1. Use CSS layout

In the development process of WeChat applet, you can use CSS layout to arrange icons. The specific implementation method is as follows:

• First, define an array in the PHP file to describe all icon information, including icon name, icon path, icon link, etc.

$icons = array(

array(
    "name" => "图标1",
    "path" => "path/to/icon1.png",
    "link" => "/pages/icon1"
),
array(
    "name" => "图标2",
    "path" => "path/to/icon2.png",
    "link" => "/pages/icon2"
),
//...

);

• Then, define a CSS style in the PHP file to set the arrangement of the icons . You can use the float attribute to make the icon float left and set an appropriate margin value.

.icon-wrapper{

width: 100%;

}

.icon{

float: left;
margin: 10px;
width: 60px;
height: 60px;
text-align: center;

}

.icon img{

display: block;

}

• Finally, use a loop statement in the PHP file to traverse all the icon information. At the same time, use HTML tags to present icon information to the mini program interface.

<?php foreach($icons as $icon): ?>
    <a class="icon" href="<?php echo $icon['link']; ?>">
        <img src="<?php echo $icon['path']; ?>" alt="<?php echo $icon['name']; ?>">
        <p><?php echo $icon['name']; ?></p>
    </a>
<?php endforeach; ?>

Through the above method, the icon can be realized in the mini program Arrangement and presentation in the interface.

2. Use Flexbox layout

In addition to using CSS layout, you can also use Flexbox layout to implement icon arrangement.

Flexbox is a flexible box layout model that can adapt to different screen sizes and has good readability and maintainability. Flexbox layout is a container-oriented model, and its design method is more concise and intuitive.

The implementation steps are as follows:

• Define a CSS style in the PHP file to set the Flexbox attribute of the parent element (that is, the container of all icons).

.icon-wrapper{

width: 100%;
display: flex;
flex-wrap: wrap;
justify-content: center;

}

• Then, define a CSS style in the PHP file to set the child elements (i.e. each icon) width, height, padding and other properties.

.icon{

width: 60px;
height: 60px;
padding: 10px;
text-align: center;

}

.icon img{

display: block;

}

• Finally, in Use loop statements in the PHP file to traverse all icon information. At the same time, use HTML tags to present icon information to the mini program interface.

<?php foreach($icons as $icon): ?>
    <a class="icon" href="<?php echo $icon['link']; ?>">
        <img src="<?php echo $icon['path']; ?>" alt="<?php echo $icon['name']; ?>">
        <p><?php echo $icon['name']; ?></p>
    </a>
<?php endforeach; ?>

Through the above method, you can use Flexbox layout Icon arrangement.

3. Use the ListView component

In addition to using CSS and Flexbox layout, you can also use the ListView component built into the mini program to implement icon arrangement.

ListView is a commonly used component in WeChat mini programs. It can display scrolling lists and supports customized styles, behaviors, event controls, etc.

The implementation steps are as follows:

• Define a CSS style in the PHP file to set the width, height, padding and other attributes of the sub-elements (that is, each icon).

.icon{

width: 60px;
height: 60px;
padding: 10px;
text-align: center;

}

.icon img{

display: block;

}

• Then, in Use the ListView component in the PHP file to traverse all icon information. Among them, the v-for instruction is used to loop through the icon information in the array, and the v-bind instruction is used to bind the icon information to the subcomponent.

<list-item v-for="(icon,index) in icons" v-bind:key="index">
    <a class="icon" href="{{icon.link}}">
        <img src="{{icon.path}}" alt="{{icon.name}}">
        <p>{{icon.name}}</p>
    </a>
</list-item>
