Solution to the failure of Smarty variable regulator, smarty variable regulator

Smarty’s variable regulator is a good thing. It has always been easy to use. However, when I used the variable regulator yesterday, I found that it didn’t work.

After a long time of fussing, it turned out that it was caused by a space. It was so unworthy! ! !

It's very simple, just look at the Smarty template manual and you will know!
