@ Check whether the ctt template is similar to the phpcms template ?? ^_^ Hey !!!
@ Micro blog http://weibo.com/lrjxgl
@ Good stuff everyone can share with us all the difficulties to extract. if you have any questions, please come up with me.
@ The default template file is. htm.

Create tpl/default/index.html

The code is as follows:

Untitled Document



1. string assignment:

{$ Str}


2. array assignment:

{Loop $ a $ v} {$ v}, {/loop}
Or

{Loop $ a $ key $ val }{$ val}, {/loop}

3. {$ subhtml}

{Subtpl ttt}

4. I used to be {$ indexurl} and now I am changed to index. php.

5. I can also echo it.

{Echo $ ec}

6. In fact, I can add, subtract, multiply, and divide 6x7x8.
{Echo 6*7*8 ;}
7. What else do you know about the common ones?

Create tpl/default/ttt.html
Creating the tpp directory is OK.
