ThinkPHP6 template engine usage guide: Create an exquisite front-end interface

Introduction:
With the development of Web applications, the design and development of front-end interfaces have become increasingly important. As a developer, we need to use a powerful template engine to help us create and manage front-end interfaces. ThinkPHP6's template engine is a powerful tool to meet this need. This article will introduce how to use the ThinkPHP6 template engine to create a beautiful front-end interface.

Part 1: Install the ThinkPHP6 template engine

Using the ThinkPHP6 template engine is very simple. You only need to execute the following command in the directory where the project is located to install:

composer require topthink/think-template

Installation completed Finally, find the view.php file in the config directory and change the value of engine to thinkTemplateEngine.

Part 2: Creation and Management of Template Files

Creating Template Files
Create a file named after the controller in the view directory of the project folder, such as index. Create a template file named after the action method in this folder, for example index.html. This template file will be used to render the corresponding operation method in the controller.
Basic structure of template files
Each template file should contain the following structure:

{__NOLAYOUT__}  // 如果不需要布局, 可以在渲染模板的時候使用這個替代
<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>標(biāo)題</title>
    <link rel="stylesheet" href="樣式文件的鏈接">
    <script src="腳本文件的鏈接"></script>
</head>
<body>
    <header>頭部內(nèi)容</header>
    
    <!-- 主體內(nèi)容 -->
    {block name="content"}這里是主體內(nèi)容{/block}

    <footer>底部內(nèi)容</footer>
</body>
</html>

In the above code, {block} is used To define labels for replaceable code blocks, you can use the assign method in the controller to replace them.

Part 3: Use of template variables and labels

Assignment of template variables
In the controller, we can use the assign method to assign The data is passed to the template file. For example:

$this->assign('name', 'ThinkPHP');
$this->assign('age', 6);

In the template file, use {$name} and {$age} to access these variables.

Process control statements
ThinkPHP6's template engine supports common process control statements, such as if, foreach, etc.

{if $name == 'ThinkPHP'}
    <h1>{$name}</h1>
{elseif $name == 'PHP'}
    <h2>{$name}</h2>
{else}
    <h3>{$name}</h3>
{/if}

<ul>
    {foreach $array as $item}
        <li>{$item}</li>
    {/foreach}
</ul>

Template inheritance and rewriting
In the template basic structure code mentioned earlier, we use {block} to define replaceable code blocks . In child templates, we can use {block} to override these code blocks.

{extend name="index/layout"}  // 繼承父模板

{block name="content"}  // 重寫content代碼塊
    <div>這是子模板中的內(nèi)容</div>
{/block}

In the above code, the child template inherits the parent template index/layout and rewrites the content code block in the parent template.

Conclusion:
Using the template engine of ThinkPHP6 can help us create and manage the front-end interface more conveniently. This article briefly introduces how to install the template engine of ThinkPHP6, and explains in detail the creation and management of template files, as well as the use of template variables and tags. By flexibly using the features of the template engine, we can easily implement a beautiful front-end interface. I hope this article can be helpful to you when using the template engine of ThinkPHP6!
