如何在smarty中使用foreach将关联数组中的值赋给复选框？

Question

我正在为smarty模板分配一个名为$ users_criteria的数组。数组如下：

$users_criteria = array(
          1 => array(
                 'label' => 'Registered users',
                 'condition' => 'date_range'
               ),
          2 => array(
                 'label' => 'Logged-in users',
                 'condition' => 'date_range'
               ),
          3 => array(
                 'label' => 'Not logged-in Users',
                 'condition' => 'date_range'
               ),
          4 => array(
                 'label' => 'Never logged-in Users'
               ),
          5 => array(
                 'label' => 'Package purchase',
                 'condition' => 'package_type'
               ),
          6 => array(
                 'label' => 'Try demo packages',
                 'condition' => 'demo_packages'
               )
        ); 
$smarty->assign('users_criteria', $users_criteria);

        $file_to_show = 'contact-list-import.tpl';

现在模板中有六个复选框，我想将上面数组中的标签值分配给每个复选框的value属性。也就是说，每个复选框都应该包含上述数组中的单个值。简而言之，我的要求是：上面数组中值为1的键应该映射到名为registered_users的复选框，上面数组中值为2的键应该映射到名为logged_in_users的复选框，......这样的方式类似到所有六个复选框。我试图实现这一点，但我得到的复选框的重复组合。我的代码如下：

{foreach from=$users_criteria key=myId item=criteria}
                  <tr height="30">
                    <td align="left" width="20%">
                    <input type="checkbox" class="user_checkbox" name="user_checkbox" id="registered_users" value="{$criteria.label}"/>Registered users &nbsp;&nbsp;  
                    </td>
                    <td valign="middle" align="left" width="10%"><b>From Date </b> : </td>
                    <td align="left" >&nbsp;<input type="text" style="width:100px;" class="inputfield" name="registered_users_from_date" id="registered_users_from_date" maxlength="10" width="20%"></td>
                    <td valign="middle" align="left" width="10%"><b>To Date </b> : </td>
                    <td>&nbsp;<input type="text" style="width:100px;" class="inputfield" name="registered_users_to_date" id="registered_users_to_date" maxlength="10" width="20%"></td> 
                  </tr>
                  <tr><td colspan="5">&nbsp;</td></tr>
                  <tr height="30">
                    <td align="left" width="20%">
                    <input type="checkbox" class="user_checkbox" name="user_checkbox" id="logged_in_users" value="{$criteria.label}"/>Logged-in users &nbsp;&nbsp;  
                    </td>
                    <td valign="middle" align="left" width="10%"><b>From Date </b> : </td>
                    <td align="left" >&nbsp;<input type="text" style="width:100px;" class="inputfield" name="registered_users_from_date" id="logged_in_users_from_date" maxlength="10"></td>
                    <td valign="middle" align="left" width="10%"><b>To Date </b> : </td>
                    <td>&nbsp;<input type="text" style="width:100px;" class="inputfield" name="registered_users_to_date" id="logged_in_users_to_date" maxlength="10"></td>
                  </tr>
                  <tr><td colspan="5">&nbsp;</td></tr>
                  <tr height="30">
                    <td align="left" width="20%">
                    <input type="checkbox" class="user_checkbox" name="user_checkbox" id="not_logged_in_users" value="{$criteria.label}"/>Not logged-in Users &nbsp;&nbsp;  
                    </td>
                    <td valign="middle" align="left" width="10%"><b>From Date </b> : </td>
                    <td align="left" >&nbsp;<input type="text" style="width:100px;" class="inputfield" name="not_logged_in_users_from_date" id="not_logged_in_users_from_date" maxlength="10"></td>
                    <td valign="middle" align="left" width="10%"><b>To Date </b> : </td>
                    <td>&nbsp;<input type="text" style="width:100px;" class="inputfield" name="not_logged_in_users_to_date" id="not_logged_in_users_to_date" maxlength="10"></td>
                  </tr>
                  <tr><td colspan="5">&nbsp;</td></tr>
                  <tr height="30">
                    <td width="300" colspan="5">
                    <input type="checkbox" class="user_checkbox" name="user_checkbox" id="never_logged_in_users" value="{$criteria.label}"/>Never logged-in Users  
                    </td>
                  </tr>
                  <tr><td colspan="5">&nbsp;</td></tr>
                  <tr height="30">
                    <td width="300" colspan="1">

                    </td>
                    <td align="left"  colspan="4">

                      {if $all_type}
                       {foreach from=$all_type item="type"}
                      <option value="{$type.package_type_id}">{$type.package_type_name}</option>
                       {/foreach}
                      {/if}
                 </select>
                  </td>
                  </tr>
                  <tr><td colspan="5">&nbsp;</td></tr>
                  <tr height="30">
                    <td width="300" colspan="5">

                    </td>
                  </tr>
                  <tr><td colspan="5">&nbsp;</td></tr>
                  {/foreach}

你可以更正代码，以便在smarty中使用foreach为复选框指定正确的值吗？提前谢谢。

您可以使用{section}代码执行此操作。我给你举个例子。

 {section name=i loop=$users_criteria}
    <tr height="30">
        <td align="left" width="20%">
        <input type="checkbox" class="user_checkbox" name="user_checkbox" id="registered_users" value="{$users_criteria[i].label}"/>Registered users &nbsp;&nbsp;  
        </td>
        <td valign="middle" align="left" width="10%"><b>From Date </b> : </td>
        <td align="left" >&nbsp;<input type="text" style="width:100px;" class="inputfield" name="registered_users_from_date" id="registered_users_from_date" maxlength="10" width="20%"></td>
        <td valign="middle" align="left" width="10%"><b>To Date </b> : </td>
        <td>&nbsp;<input type="text" style="width:100px;" class="inputfield" name="registered_users_to_date" id="registered_users_to_date" maxlength="10" width="20%"></td> 
    </tr>
    <tr><td colspan="5">&nbsp;</td></tr>
 {/section}
