thinkphp5 template cannot be loaded automatically

How to solve the problem that the thinkphp5 template cannot be loaded automatically

In the process of developing the thinkphp5 framework, we often use template rendering to render the page, but sometimes we encounter a problem that the template cannot Autoloading issue. This problem may be troublesome for some novice programmers, so this article will introduce some common solutions to help you better solve this problem.

First of all, let’s take a look at the automatic loading mechanism of thinkphp5 template.

In the thinkphp5 framework, the template will automatically find the corresponding template file for rendering according to the naming rules of the controller. For example, if there is a controller file called Index.php, then the framework will look for the /views/Index/index.html template file by default. In the template file, you can use some simple syntax to perform operations such as variable output, conditional judgment, and loop traversal. For example, you can use {{$name}} to output the value of the $name variable.

But if we find that when using the above syntax for template rendering, the template corresponding to the controller cannot be automatically loaded, then we need to troubleshoot related problems and solutions.

Common troubleshooting:

1. Check whether the template file path is correct.

In the thinkphp5 framework, template files are stored in the /views folder, and the template files corresponding to the corresponding controller should be stored in /views/controller name/file name.html. Therefore, we need to check whether the path to our template file is correct, whether it is placed in the correct folder, and whether the file name is correct.

2. Check if the controller is named correctly.

As mentioned before, the template automatic loading mechanism of the thinkphp5 framework finds the corresponding template file based on the naming rules of the controller. Therefore, if our controller naming does not comply with the specification, it will also cause the template to fail to load automatically. The correct controller naming rule should be camel case naming, such as IndexController, GoodsController, etc.

3. Check whether the template file is named correctly.

In the thinkphp5 framework, the template file name should be consistent with the template file name under the corresponding controller. For example, the template file under the Index controller should be called index.html. If the template file under the controller is not named correctly, the template will not be automatically loaded.

4. Check whether cache is used.

Sometimes we enable caching when rendering templates. At this time, if we update the template file but the cache is not cleared, the new template will not be loaded. Therefore, if we encounter automatic loading problems when rendering templates, we can try clearing the cache to solve it.

Solution:

1. Check the template file path

After troubleshooting the above common problems, if the template still cannot be loaded automatically, we can try to manually Render template. We can use the following code to manually render the template:

public function index() {

$view = new     hinkView();

$view->assign('name', 'Hello,World');

return $view->fetch('index',['name'=>$name]);

}

2. Force to specify the template path and file name

If manually rendering the template still cannot solve the problem, we can try to use force Specify the template path and file name to solve the problem. We can add the following code to the controller:

public function index() {

return $this->fetch(ROOT_PATH . 'views/index/index.html');

}

This way we can directly specify the path and file name of the template, which can effectively solve the automatic loading problem.

3. Modify the config configuration file

Finally, if the above method still cannot solve the problem, we can try to modify the relevant settings in the config configuration file to solve the problem. We can add the following code to the config.php file:

'view_replace_str' => [

'__PUBLIC__'=>'/static',

'__ROOT__' => '/',

'__INDEX__' => '/index.php/Index',

],

This way we can load the template file in the form of /Index/index.html when rendering the template, effectively solving the automatic loading problem.

Summary:

The automatic loading of templates is a common problem in thinkphp5 framework development, but it is also a relatively easy problem to solve. If we encounter such a problem, we can troubleshoot and solve it according to the above methods to make our thinkphp5 framework development smoother.
