In web development, page modification is an extremely common task. When using the thinkphp framework for web development, the page modification operation also has some special features. This article will introduce the page modification under the thinkphp framework from the following aspects:

Page rendering

In the thinkphp framework, page rendering is implemented through the controller . We usually write the corresponding business logic in the controller, and then pass the data processed by the business logic to the view layer for rendering. The thinkphp framework provides a wealth of view layer tools through which we can easily render data onto the page.

The following is a simple example that demonstrates how to render the page in the controller:

public function index()
{
    $data = [
        'name' => '张三',
        'age' => 22,
    ];
    // 将$data传递给视图层，并指定视图模板名称
    return $this->fetch('index', $data);
}

In the above code, we first define a $data array and save some data to this array middle. Then, we pass this array to the view layer and specify the view template name as index. Finally, we use the fetch method to render the data onto the page.

View template

In the thinkphp framework, the view template is the core part of the page. View templates can help us write pages quickly, and at the same time, they can separate page styles and data. The thinkphp framework provides a variety of view template engines, such as PHP native template engine, smarty, etc. These engines allow us to easily write view templates.

The following is a simple smarty template example:

<!doctype html>
<html>
<head>
    <meta charset="utf-8">
    <title>{$name}的个人资料</title>
</head>

<body>
    <h1>{$name}的个人资料</h1>
    <ul>
        <li>姓名：{$name}</li>
        <li>年龄：{$age}</li>
    </ul>
</body>
</html>

In the above example, we used the smarty template engine to write a simple view template. Variables are used in the template to output data, and some simple logical judgments and other operations can also be embedded.

Page jump

In web development, page jump is a very common operation. The thinkphp framework provides a wealth of page jump methods, allowing us to easily implement the page jump function.

The following is a simple page jump example:

public function modify()
{
    // 进行相应业务处理
    // ...

    // 执行页面跳转操作
    $this->success('修改成功', 'index');
}

Copy after login

In the above code, we first perform the corresponding business processing, and then use the success method to implement the page jump. The success method has two parameters. The first parameter represents the prompt information of successful jump, and the second parameter represents the page address of the jump.

Form submission

Form submission is a very important function. In the thinkphp framework, we can easily obtain the data submitted by the form through the request object. At the same time, the thinkphp framework also provides some form validation tools, which can effectively avoid unnecessary errors.

The following is a simple form submission example:

<form action="/form/submit" method="post">
    <input type="text" name="name" placeholder="请输入你的姓名">
    <input type="text" name="age" placeholder="请输入你的年龄">
    <button type="submit">提交</button>
</form>

Copy after login

The above code is a simple form submission example. We can submit the form data to the /form/submit address through POST. In the controller, we can use the request object to obtain the data submitted by the form:

public function submit()
{
    // 获取表单数据，这里我们假设提交的表单字段为name和age
    $name = $this->request->post('name');
    $age = $this->request->post('age');

    // 进行相应业务处理
    // ...

    // 页面跳转
    $this->success('提交成功', 'index');
}

Copy after login

In the above code, we first use the request object to obtain the data submitted by the form, then perform the corresponding business processing, and finally implement the page jump change.

Summary

Page modification is a very common requirement in web development. Using the thinkphp framework allows us to realize the page modification function more easily. In actual development, we also need to combine specific business needs and choose appropriate methods and tools to implement the page modification function. This article only briefly introduces page rendering, view templates, page jumps, form submission, etc. Readers are invited to explore on their own for more knowledge related to the thinkphp framework.
