How to Use udfs in the Thinkphp Template

Note: User-defined functions should be stored in the project application directory/common. php. Here is the key.

Template variable function call format: {$ varname | function1 | function2 = arg1, arg2 ,###}

Note:

{There must be no space between the symbol and the $ symbol, so there is no problem with the space of the following parameter;

### Parameter location of the template variable itself;

Multiple functions are supported, and spaces are supported between functions;

Function shielding is supported. In the configuration file, you can configure a list of Disabled functions;

Variable caching is supported. Repeated variable strings are parsed several times.

Example:

{$ WebTitle | md5 | strtoupper | substr = 0, 3}

{$ Number | number_format = 2}

{$ Varname | function1 | function2 = arg1, arg2 ,###}

Instance:
Copy codeThe Code is as follows:
Function Cate ($ cid ){
$ Cate = D ('cate ');
$ Cate = $ Cate-> where ('Id = '. $ cid)-> find ();
Return $ Cate ['title'];
}

I want to call this function in the template, so you can write it like this in the template.

{$ Vo. cid | cate ###}
