I downloaded the smarty 3.1.8 unzip smarty-stable.zip] Feb 20th, 2012 files from the Smarty official website.
The stable word is stable. I just decompress this package and copy the libs folder to my www/smarty directory,
Other statements like running {$ smarty. server. SERVER_ADDR} in the temp. tpl template can be displayed normally. Why can't I just run config_load and UDF above?


------ Solution --------------------
Google, it turned out to be like this.
3.0 was previously implemented using register_function, and now the new method registerPlugin is used.
$ Smarty-> registerPlugin ("function", "demo", "demotest"); // specifies the type, which is called by a function. specify the template function name and php function name.
Function demotest ($ params ){
Extract ($ params); // get parameters a and B
Echo $ a. $ B; // output
}

Template syntax:
{Demo a = "2" B = "test "}
Output: 2 test

However, an error still occurs when {config_load} is used in the template. how can this problem be solved?
------ Solution --------------------
Ah, the config_load error is fixed.
I wrote {config_load file = "a. conf"} directly in the temp. tpl template "}
Create the configs folder in the temp. tpl file and put a. conf in the folder,
Strangely, I didn't specify a. conf in the configs folder. How did I find it?
This is because {config_load file = "../configs/a. conf"} should be written in temp. tpl.
What's going on?
How did smarty3.0 find it?
