PHP結果未顯示在smarty模板中

Question

我有一個變量$my_arr其變量var_dump($my_arr)值為

array(3) { [0]=> object(stdClass)#6 (9) { ["prod_index"]=> string(1) "1" ["prod_code"]=> string(4) "amp1" ["prod_name"]=> string(11) "Amplifier A" ["prod_price"]=> string(6) "100.00" ["frequency"]=> string(1) "2" ["gain"]=> string(1) "2" ["gain_variation"]=> string(3) "0.2" ["noise"]=> string(1) "2" ["power"]=> string(2) "10" } [1]=> object(stdClass)#7 (9) { ["prod_index"]=> string(1) "3" ["prod_code"]=> string(4) "amp1" ["prod_name"]=> string(13) "Amplifire1.33" ["prod_price"]=> string(6) "133.00" ["frequency"]=> string(4) "2.12" ["gain"]=> string(1) "2" ["gain_variation"]=> string(3) "0.2" ["noise"]=> string(1) "2" ["power"]=> string(2) "10" } [2]=> object(stdClass)#8 (9) { ["prod_index"]=> string(1) "4" ["prod_code"]=> string(4) "amp1" ["prod_name"]=> string(13) "Amplifier1.45" ["prod_price"]=> string(6) "150.00" ["frequency"]=> string(4) "2.99" ["gain"]=> string(1) "2" ["gain_variation"]=> string(3) "0.2" ["noise"]=> string(1) "2" ["power"]=> string(2) "10" } } 

在聰明人中，我嘗試了

{foreach name = fe1 item = k from = arr}
{$k->prod_index}    
{/foreach}

但這沒有顯示任何結果。

假設您已經將數組分配給smarty，例如：

$smarty->assign( "arr", $my_arr );

您需要使用“。” 語法，例如：

{foreach name = fe1 item = k from = arr}
{$k.prod_index}    
{/foreach}
