PHP foreach循环不会出现在两行中

执行此代码我得到一个类别列表。它显示如下

enter image description here

我的代码如下所示：

<tr>
 <td align="right">
    <legend><?php _e( 'Category', self::nspace ); ?></legend>
 </td>
 <td>
    <div class="radio-group">
       <?php foreach ( $this->get_media_categories() as $slug => $name ): ?>
       <label>
             <tr>
                <td>
                   <input type="checkbox" name="media-categories[]" value="<?php echo $slug; ?>"<?php if ( in_array( $slug, $_REQUEST['media-categories'] ) ): ?> checked<?php endif; ?>> 
                   <?php echo $name; ?>
                </td>
             </tr>

       </label>
       <?php endforeach; ?>
    </div>
 </td>
</tr>

我希望它显示在两列中：

category X        category X
category X        category X
category X        category X
category X        category X
category X        category X

我的问题是我应该如何打破每个循环使其看起来像那样？

        </p>
      </td>
    </tr>
    <tr>
      <td>
      <td align="center" >

      </td>
      <td> </td>
    </tr>
  </table>
</form>
<?php if ( isset( $_REQUEST['keyword'] ) || isset( $_REQUEST['media-categories'] ) )  $this->mediacat_library( true ); ?>

您只需使用CSS column-count：

即可 
.radio-group {
    column-count: 2;
}

您需要使用计数器来跟踪和分解列。请查看以下代码。

<tr>
    <td align="right">
       <legend><?php _e( 'Category', self::nspace ); ?></legend>
    </td>
    <td>
       <div class="radio-group">
          <?php 
              $count = 0;
              foreach ( $this->get_media_categories() as $slug => $name ): ?>
          <?php if(($count%2) == 0) : ?>
           <label>
                <tr>
          <?php endif; ?>           
                   <td>
                      <input type="checkbox" name="media-categories[]" value="<?php echo $slug; ?>"<?php if ( in_array( $slug, $_REQUEST['media-categories'] ) ): ?> checked<?php endif; ?>> 
                      <?php echo $name; ?>
                   </td>
           <?php if(($count%2) == 0) : ?>
                </tr>
           </label>
          <?php endif; ?>
           <?php $count++; ?>
          <?php endforeach; ?>
       </div>
    </td>
 </tr>

您正在为每列使用行。您需要在每2 tr次td后使用正确的table结构关闭tr。目前，您正在td内打印<div class="radio-group"> <table> <tr> <?php $i = 0; foreach ( $this->get_media_categories() as $slug => $name ): ?> <td> <input type="checkbox" name="media-categories[]" value="<?php echo $slug; ?>"<?php if ( in_array( $slug, $_REQUEST['media-categories'] ) ): ?> checked<?php endif; ?>> <?php echo $name; ?> </td> <?php $i++; if($i%2 == 0) { echo "</tr><tr>"; } endforeach; ?> </tr> </table> </div> 。试试 - 

<ul>
<?php foreach ( $this->get_media_categories() as $slug => $name ): ?>
    <li>
         <label>
                <input type="checkbox" name="media-categories[]" value="<?php echo $slug; ?>"<?php if ( in_array( $slug, $_REQUEST['media-categories'] ) ): ?> checked<?php endif; ?>> 
                <?php echo $name; ?>
         </label>
    </li>
<?php endforeach; ?>
</ul>

另一个解决方案是 - 

li {
    list-style: none;
    width: 50%;
    display: inline-block;
    /*rest of the styles*/
}

CSS 将是 - 

<div class="md-dialog-main">
                        <table class="me-hours-table">
                            <thead>
                                <th>Product Type</th>
                                <th>Product Name</th>
                                <th>
                                    <select>
                                        <option  style="background-color:'#FF0000'">weight</option>
                                        <option  style="background-color:'#FF0000'">size</option>
                                    </select>
                                </th>
                                <th>Price</th>
                                <th>Qty</th>
                            </thead>
                            <tbody>
                                <tr ng-repeat="data in variants">
                                    <td>{{data.type}}</td>
                                    <td>{{data.name}}</td>
                                    <td>{{data.size}}</td>
                                    <td>{{data.price}}</td>
                                    <td>{{data.qty}}</td>
                                </tr>

                            </tbody>
                        </table>
                    </div>

您可以尝试以下内容：

我没有测试过这段代码，但我认为它会起作用。这是一个简单的计数器组合。

<?php
$tdCount = 0;
$tabletd = ''; 
foreach ( $this->get_media_categories() as $slug => $name ): ?>
           <label>
                <?php if($tdCount == 2) { ?>
                 <tr>
                    <?php echo $tabletd;?>
                 </tr>
                 <?php
                    $tdCount = 0;
                    $tabletd = ''; 
                  }
                    $tdCount++;
                    $checked = '';
                    if ( in_array( $slug, $_REQUEST['media-categories'] ) ){ $checked = 'checked';}
                    $tabletd.= '<td>
             <input type="checkbox" name="media-categories[]" value="'.$slug.'" '.$checked.'> 
             '.$name.'
                     </td>';
                   ?>

           </label>
<?php endforeach; ?>
<?php if($tabletd!= '')  {?>
<label>
                 <tr>
                    <?php echo $tabletd;?>
                 </tr>
           </label>
<?php } ?>
