The variable regulator of Smarty is a good thing, and it has always been easy to use. It can be found that it doesn't work when I used the variable regulator yesterday.

The Code is as follows:

{$ Name | upper}

I carefully read the manual, read the smarty loading path, and checked it up and down for nearly an hour without finding the problem. The code will be deleted and re-written into a helpless dilemma.

The Code is as follows:

{$ Name | upper}

The result is good. It turns out that the variable must be directly followed by a vertical line, function name, and no space in the middle. Otherwise, the function of the variable regulator will become invalid. After a long time, it turned out to be caused by a space. It's not worth it !!!

It seems that the smarty program will be called later. Pay attention to the space issue ~, Other problems may also be caused by spaces, which are the least likely to be discovered.
