This article mainly introduces the relevant information about thinkphp5's method of loading static resource paths and constants. Friends who need it can refer to it. I hope it can help everyone.

1. Load static resource path

Versions greater than 5.0.4 can be used directly

__ROOT__: project directory

__STATIC__: The static directory under the project directory

__JS__: The static/js directory under the project directory

__CSS__: The static/css directory under the project directory

We can use the view template to print The specific paths of these constants

<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Insert title here</title>
</head>
<body>
__ROOT__<br>
__STATIC__<br>
__JS__<br>
__CSS__<br>
</body>
</html>

The page output is as follows:

/
/projectname/public/static
/projectname/public/static/js
/projectname/public/static/css

Open the config file in the application folder, You can customize resource constants according to your own needs. After defining the constants, you can use them in the template file.

For example:

<?php
return [ 
 &#39;view_replace_str&#39; => [ 
  &#39;__PUBLIC__&#39;=>&#39;../public/static/admin&#39;,
  &#39;__ROOT__&#39; => &#39;/&#39;,
  &#39;__APP__&#39; => &#39;app/admin/&#39;,
 ]
];
