高分求这样的数组为什么循环输出不对,smarty模版

Question

我用的是smarty模版，这样的代码在HTML页面怎样输出呢这是数组array(2) {
  ["citys"]=>
  array(2) {
    [0]=>
    array(4) {
      ["city_id"]=>
      string(1) "1"
      ["province_id"]=>
      string(1) "1"
      ["city_name"]=>
      string(6) "合肥"
      ["city_enname"]=>
      string(5) "HEFEI"
    }
    [1]=>
    array(4) {
      ["city_id"]=>
      string(1) "2"
      ["province_id"]=>
      string(1) "1"
      ["city_name"]=>
      string(6) "蚌埠"
      ["city_enname"]=>
      string(6) "BENGBU"
    }
  }
  ["sowntowns"]=>
  array(2) {
    [1]=>
    array(1) {
      [0]=>
      array(4) {
        ["city_id"]=>
        string(1) "1"
        ["sowntown_id"]=>
        string(6) "000001"
        ["sowntown_name"]=>
        string(18) "长江"
        ["sowntown_eng_name"]=>
        string(21) "ChangJiang"
      }
    }
    [2]=>
    array(1) {
      [0]=>
      array(4) {
        ["city_id"]=>
        string(1) "2"
        ["sowntown_id"]=>
        string(6) "000009"
        ["sowntown_name"]=>
        string(9) "风景区"
        ["sowntown_eng_name"]=>
        string(10) "FengJingQu"
      }
    }
  }
}这是模版页面   {{foreach from=$sowntown_hotel item=shopping key=key}}
    <p class="fb mt10">{{$shopping.citys.city_name}}商圈</p>
    <ul class="sitemap_list clearfix">
    {{foreach from=$shopping.sowntowns item=sown}}
    <li><a href="#">{{$sown.sowntown_name}}</a></li>
    {{/foreach}}
    </ul>
    {{/foreach}}

Answer 1

$shopping.citys里面还需要循环，你试一试
$shopping.citys.0.city_name就明白了

Answer 2

$shopping.citys.0.city_name之后只循环出2个，而且$shopping.citys.0.city_name都为空

Answer 3

改成这样还是不对啊
  {{foreach name=name item=shopping from=$sowntown_hotel}}
  {{foreach from=shopping.citys item=citys}}
   <p class="fb mt10">{{$citys.city_name}}商圈</p>
   {{/foreach}}
    <ul class="sitemap_list clearfix">
   <!--{{foreach from=$shopping.sowntowns item=sown}}
    <li><a href="#">{{$sown.sowntown_name}}</a></li>
    {{/foreach}}-->
    </ul>
    {{/foreach}}

Answer 4

   {{foreach from=$sowntown_hotel.citys item=shopping key=key}}
        {{foreach from=$shopping.citys item=city}}
        <p class="fb mt10">{{$city.city_name}}商圈</p>
        {{/foreach}}
        <ul class="sitemap_list clearfix">
            {{foreach from=$shopping.sowntowns item=sown}}
            <li><a href="#">{{$sown.sowntown_name}}</a></li>
            {{/foreach}}
        </ul>
    {{/foreach}}

Answer 5

$sowntown_hotel = array(
"citys"=> array(0 => array(
"city_id" => "1", 
"province_id"=> "1", 
"city_name"=> "合肥", 
"city_enname"=> "HEFEI"
),
1 => array(
"city_id" => "2", 
"province_id"=> "1", 
"city_name"=> "蚌埠", 
"city_enname"=> "BENGBU"
)
), 
"sowntowns" => array(
1 => array(
0 => array(
"city_id" => "1", 
"sowntown_id" => "000001", 
"sowntown_name"=> "长江", 
"sowntown_eng_name"=> "ChangJiang"
)
), 
2 => array(
0 => array(
"city_id" => "2", 
"sowntown_id"=> "000009", 
"sowntown_name" => 
"风景区", 
"sowntown_eng_name"=> "FengJingQu"
)
)
)
);
这个你应该看得出来才对啊

Answer 6

关联键 sowntowns 的部分是错误的
把第三维收上来就可以了
"sowntowns" => array(
                1 => array(
                        "city_id" => "1", 
                        "sowntown_id" => "000001", 
                        "sowntown_name"=> "长江", 
                        "sowntown_eng_name"=> "ChangJiang"
                ), 
                2 => array(
                        "city_id" => "2", 
                        "sowntown_id"=> "000009", 
                        "sowntown_name" => 
                        "风景区", 
                        "sowntown_eng_name"=> "FengJingQu"
                )
            )

Answer 7

结构很蛋疼 citys和sowntowns的关联你也没说清楚
另外长江和合肥、蚌埠有关联吗？{{foreach name=name item=citys from=$sowntown_hotel.citys}}
<p class="fb mt10">{{$citys.city_name}}商圈</p> {{assign name=temp value=$sowntown_hotel.sowntowns}}
{{foreach name=name item=sowntowns from=$temp[$citys.city_id]}}
<li><a href="#">{{$temp.sowntown_name}}</a></li>
{{/foreach}}
{{/foreach}}
