smarty foreach

Question

新手吧例如：<{foreach key=key item=item from=$ALL_PROJECT_RESULTS}>
姓名：<{$item}>
<{/foreach}>

Answer 1

$all_project_results这里面是空的，怎么能出来内容呢

Answer 2

if(!empty($all_project_results)){
foreach($all_project_results as $key=>$project_row){
$all_project_results[$key]['user_name'] = $project_row['user_name'];
$all_project_results[$key]['pic'] = $project_row['pic'];
$all_project_results[$key]['tel'] = cnsubstr($project_row['tel']);
$all_project_results[$key]['mail'] = cnsubstr($project_row['mail']);  
}
$smarty->assign('ALL_PROJECT_RESULTS',$all_project_results);
 }试一试

Answer 3

其实$smarty->assign('ALL_PROJECT_RESULTS',$all_project_results);没执行

Answer 4

if(!empty($all_project_results)){//应该是非空吧
