在smarty中显示数组元素 [英] Display array elements in smarty
问题描述
我合并了两个mysql结果:
I have merged two mysql results :
while($rs_1 = mysql_fetch_array($r1))
{
$arr1[] = $rs_1;
}
while($rs_2 = mysql_fetch_array($r2))
{
$arr2[] = $rs_2;
}
$resN = array_merge($arr1,$arr2);
var_dump($resN)
显示以下结果:
array(5) {
[0] => array(4) {
[0] => string(6) "Petric"
["bz_pro_first_name"] => string(6) "Petric"
[1] => string(8) "Naughton"
["bz_pro_last_name"] => string(8) "Naughton"
}
[1] => array(4) {
[0] => string(6) "Nitish"
["bz_pro_first_name"] => string(6) "Nitish"
[1] => string(12) "Dolakasharia"
["bz_pro_last_name"] => string(12) "Dolakasharia"
}
[2] => array(4) {
[0] => string(6) "Martin"
["bz_pro_first_name"] => string(6) "Martin"
[1] => string(3) "Rom"
["bz_pro_last_name"] => string(3) "Rom"
}
[3] => array(4) {
[0] => string(5) "Steve"
["bz_pro_first_name"] => string(5) "Steve"
[1] => string(5) "Wough"
["bz_pro_last_name"] => string(5) "Wough"
}
[4] => array(4) {
[0] => string(3) "Liz"
["bz_pro_first_name"] => string(3) "Liz"
[1] => string(6) "Hurley"
["bz_pro_last_name"] => string(6) "Hurley"
}
}
我应该巧妙地展示它们:
I am supposed to display them in smarty so :
assign_values('rand_ad',$ resN);
assign_values('rand_ad',$resN);
现在,我试图像这样聪明地展示:
Now I tried to display in smarty like this :
{foreach name=outer item=pro from=$rand_pro}
{foreach key=key item=item from=$pro}
{$key}: {$item}<br />
{/foreach}
{/foreach}
它按顺序显示结果.我需要提取某些位置的值.那么如何提取值,例如名字,姓氏等?
It displays the results but serially. I need to extract the values in some positions . So how can I extract the values eg first name, last name etc ?
推荐答案
您没有给出所需输出的示例,所以我会猜测一下.假设您正在寻找上面的数组的以下输出:
You didn't give an example output of what you wanted, so I'll take a guess. Assuming you are looking for the following output for the array above:
0: Petric Naughton<br />
1: Nitish Dolakasharia<br />
2: Martin Rom<br />
3: Steve Wough<br />
4: Liz Hurley<br />
您可以这样做:
{foreach from=$rand_pro item=pro key=pro_key}
{$pro_key}: {$pro.bz_pro_first_name} {$pro.bz_pro_last_name}<br />
{/foreach}
如果我的假设不正确,请使用您期望更加清晰的输出来更新您的问题.
If I am assuming incorrectly, please update your question with the output you are expecting to be more clear.
