You can assign values directly to the template, or assign values to array elements too. 這是{assign}函數的簡寫版，你可以直接賦值給模版，也可以為數組元素賦值。 <table width="80%" border="0" cellpadding="2" cellspacing="2" class="note"><caption> 提示 </caption> <tr><td>Note<br/>Assignment of variables in-template is essentially placing application logic into the presentation that may be better handled in PHP.
