thinkphp3.2.3 u method passes parameters
May 29, 2023 am 11:02 AMThinkphp3.2.3 is a popular open source PHP framework that can easily develop web applications and provides rich application development functions. In Thinkphp3.2.3, the u method is a very commonly used function for generating URL paths. When using the u method, we may need to pass some parameters to the URL. This article will introduce how to use the u method to pass in Thinkphp3.2.3 parameter.
1. Introduction to u method
In Thinkphp3.2.3, u method is used to generate URL path, and its syntax is as follows:
1 |
|
Among them, the controller/operation method is specified The controller and action method of the URL path to be generated, the parameter specifies the parameters to be passed to the action method, the pseudo-static suffix specifies the suffix of the generated URL (such as .html), whether to display the domain name specifies whether to include the domain name in the URL.
2. Pass parameters in the u method
In Thinkphp3.2.3, we can use data types such as arrays, strings or objects to pass parameters. Below we will introduce how to use these data types to pass parameters.
1. Use an array to pass parameters
When using an array to pass parameters, we can pass the parameters to the u method as an associative array. For example:
1 2 3 4 5 |
|
In the above code, $params is an associative array containing two key-value pairs. We pass $params as parameters to the u method to generate a URL path. In the controller's operation method, we can use the $_GET super global array to obtain these parameters, as follows:
1 2 3 4 5 6 7 |
|
2. Use strings to pass parameters
When using strings to pass parameters, We can splice the parameters directly into the URL path, for example:
1 |
|
In the controller's operation method, we can use the parse_str function to parse the parameters into an array, as follows:
1 2 3 4 5 6 7 8 |
|
3 , Use objects to pass parameters
When using objects to pass parameters, we can pass the parameters to the u method as attributes of the object. For example:
1 2 3 4 5 6 7 8 |
|
In the operation method of the controller, we can use the properties of the object to obtain these parameters, as follows:
1 2 3 4 5 6 7 |
|
3. Precautions
When using u When passing parameters through the method, you need to pay attention to the following points:
1. If the parameter contains special characters (such as slashes), you need to use the urlencode function for encoding;
2. If the parameter contains Chinese Characters need to be encoded using the urlencode function, or the character set is set in the u method, for example:
1 |
|
In the controller's operation method, you need to use the urldecode function to decode, for example:
1 |
|
3. The order of passing parameters has an impact on the generation of URL paths. For example:
1 2 |
|
The URL paths generated by $url1 and $url2 will be different.
4. Summary
The above are the methods and precautions for using the u method to pass parameters in Thinkphp3.2.3. I hope it will be helpful to everyone's development. When using the u method to pass parameters, you need to select the appropriate parameter type according to the actual situation and follow the precautions.
