The method to create a custom layout in the Yii framework includes the following steps: 1. Locate the default layout file main.php and copy it to custom.php; 2. Modify the content of custom.php to adjust the HTML structure, style, and scripts; 3. Specify the use of a new layout in the controller or view, such as $this->layout = 'custom'; 4. Optionally set the global default layout and add 'layout' => 'custom' in the configuration file. After completing these steps, you can achieve personalized control of page layout.
In the Yii framework, creating a custom layout is not complicated, and it is mainly achieved by modifying the view files and configurations. Yii's layout mechanism allows you to set a unified look and style for the entire website or for a specific page. Let’s take a look at how to achieve this goal step by step.
1. Find the default layout file
Yii The default layout file is usually located in views/layouts/main.php (for Yii2). You can open this file to see the content structure inside. It usually contains HTML skeletons, such as , , tags, as well as some common CSS and JS references.
If you want to create a new layout, the easiest way is to copy the file and rename it to the name you need, such as custom.php .
2. Create your custom layout file
After copying the original main.php and rename it to custom.php , you can modify its contents as needed. For example:
- Change the overall HTML structure
- Replace CSS stylesheet
- Add a new JS script
- Modify the head or bottom area of the page
For example, if you want a page to use a completely different navigation bar style, you can directly adjust the corresponding HTML structure in this layout file.
3. Specify the use of the new layout in the controller or view
After creating the layout file, the next step is to call it in a specific place. There are two common ways:
- Specify in the controller:
public function actionIndex()
{
$this->layout = 'custom'; // Note that there is no .php suffix return $this->render('index');
}In this way, all actions under the controller will use this new layout unless you reset it in other actions.
- Specify in the view (more flexible):
Add this line of code to the beginning of the specific view file:
<?php $this->beginPage(); $this->layout = 'custom'; ?>
This method is suitable for customization only for a specific page.
4. Set global default layout (optional)
If you want the entire site to use this new layout by default, you can modify it in the configuration file:
Open config/web.php or module configuration file and add it to the view configuration under components :
'view' => [
'theme' => '@app/themes/basic',
'defaultExtension' => 'php',
'layout' => 'custom', // Set the default layout here],Note, however, that this will affect all pages that do not have a separate layout.
Basically these are the operations. Although the steps seem to be quite a lot, each step is not complicated. The key is to figure out which place controls which part of the content. As long as the layout file is in the correct position and the reference method is correct, it will take effect smoothly.
