Thinkphp using functions and callback method instances in auto-completion, thinkphp callbacks


This article describes the use of functions and callback methods in thinkphp auto-completion. Share to everyone for your reference. Here's how:

The thinkphp auto-fill format is as follows:
Copy the Code code as follows: Array (fill field, fill content [, fill condition] [, additional rules])

Additional rules, optional, include:

String that represents the fill content as a string (default).

Functions: A function is used to indicate that the content of a fill is a function return value.

Callback: The method used to indicate that the content of the fill is a method return value for the current Model.

Field: The value that indicates that the filled content is one of the other fields.

thinkphp Auto-fill using function functions

When additional rules are populated with function functions, the content that represents the fill is a function return value, which can be a PHP built-in function or a user-defined function.

Use the function to populate the example:
Copy the Code code as follows: Class Usermodel extends model{
Protected $_auto = Array (
Use the MD5 function with the password field in all cases
Array (' Password ', ' MD5 ', 3, ' function '),
Writes the current timestamp to the RegDate field when new
Array (' regdate ', ' time ', 1, ' function '),
Write user registered IP address to REGIP field when new
Array (' Regip ', ' get_client_ip ', 1, ' function '),
Use the custom GetName function for the username field when new
Array (' username ', ' get_name ', 1, ' function '),
);
}
In the example above, the MD5 and time used for PHP built-in functions, the result is MD5 ($_post[' password ') value and time () function value, GET_CLIENT_IP and Get_name are common/common.php Custom functions.

the Get_name function adds the user name to the th_ prefix, as follows:
Copy the Code code as follows: function Get_name ($name) {
Return ' Th_ '. $name;
}
If the function requires parameters, the fields are populated as parameters, such as the MD5 and get_name functions above.

thinkphp Auto-fill using method callback

When using the method callback fill, the content that represents the fill is a method return value for the current Model, using the callback fill example:
Copy the Code code as follows: Class Usermodel extends model{
Protected $_auto = Array (
Callback GetName method for username field when new
Array (' username ', ' getName ', 1, ' callback '),
);
}
the GetName method adds the user name to the th_ prefix , as follows:
Copy the Code code as follows: Class Usermodel extends model{
Append the incoming username to the th_ prefix
function GetName () {
Return ' th_ '. $_post[' username '];
}
}
Note: The above example populates the username with the th_ prefix before the username field, only to illustrate the use of autofill using functions or callback methods, which may not be of practical production significance

It is hoped that this article will be helpful to everyone's thinkphp framework design.
