RainTPL循環進入循環

Question

我必須使用循環進入子循環。我不能在父循環中使用子循環。

例如，這是我的示例代碼

{loop="user_list"} 
    {$key} - {$value.name}</br> 
    {loop="list"} 
    {$key} - {$value.id}</br> 
    {/loop} 
{/loop} 

Answer 1

Try adding $ to your variables. 

{loop="$user_list"} 
    {$key} - {$value.name}</br> 
    {loop="$list"} 
     {$key} - {$value.id}</br> 
    {/loop} 
{/loop} 

Below one sample that worked for me with RainTPL3: 

{loop="$letters"} 
    {$key} - {$value.name}</br> 
    {loop="$numbers"} 
     {$key} - {$value.id}</br> 
    {/loop} 
{/loop} 


- Input: 
$letters = array("A" => array("name" => "Letter A"), 
        "B" => array("name" => "Letter B"), 
        "C" => array("name" => "Letter C")); 
$numbers = array(0 => array("id" => "Number 0"), 
       1 => array("id" => "Number 1"), 
       2 => array("id" => "Number 2")); 

- Output: 

A - Letter A 
0 - Number 0 
1 - Number 1 
2 - Number 2 
B - Letter B 
0 - Number 0 
1 - Number 1 
2 - Number 2 
C - Letter C 
0 - Number 0 
1 - Number 1 
2 - Number 2
