Question

我有一个php循环列出了50个无线电盒子。我想在每列上放10个无线电盒。我试过了：

div style =“overflow：hidden; white-space：nowrap; 浮动：左;宽度：160像素;“＆GT;

生成代码：

 {php} $j=0; {/php} 
                {foreach from=$genreLists item=genreList key = genre_key}
                {if $genre_key <= 250}
                div id="genrecheck_{$genreList}">
              input name="genre[]" type="checkbox" id="genre[]" value="{$genreList}" {section  name = rows loop = $smarty.request.genre} {if $genreList ==  $smarty.request.genre[rows]} checked {/if}{/section} onClick="getval(this,'genrecheck_{$genreList}');">
                div id="genre_{$genre_key}" style="display:none;">{$genreList}/div>div id="genre1_{$genre_key}" style="display:inline;">{$genreList} /div>
                /div>
                {php} $j++; if($j%5==0) { echo "
                "; $j=0; } {/php} {/if}{/foreach}

似乎它不起作用。有什么建议？请注意：收音机盒使用php循环回显。

我发现处理将复选框拆分成列的最佳方法是使用array_chunk（）函数将数组拆分为相等的子数组，然后使用双foreach循环来渲染列。

http://php.net/manual/en/function.array-chunk.php

echo '<div class="container">';
foreach(array_chunk($genreLists,5) as $row_value)
{
  echo '<div class="row">';
  foreach($row_value as $cell_key => $cell_value)
  {
    echo '<div class="cell">';
    //echo your checkbox html here
    echo '</div>'; // close cell
  }
  echo '</div>'; // close row
}
echo '</div>'; // close container

如果在将array_chunk分配给模板引擎之前执行array_chunk，则可以使用smarty {foreach}循环完成相同的概念。实际上，聪明的{$ var | array_chunk：5}应该作为修饰语

如果要将复选框垂直显示，请改用此函数：

/* ----------[ func ARRAY CHUNK VERTICAL ]----------
A sister to array_chunk, but instead of horizontal, split
the data vertical
*/
function array_chunk_vertical($array = null,$cols = 3, $pad = array(null))
{
  if (is_array($array) == true and !empty($array))
  {
    // total items in the array
    $count = count($array);
    // if count is empty
    if(empty($count))
    {
      return false;
    }
    // if cols is some how still empty
    if(empty($cols))
    {
      $cols = 3;
    }
    // count the number of vertical rows
    $rows = ceil($count/$cols);
    // group the array into colums
    $array = array_chunk($array,$rows);
    // if the array is less that the number of cols required
    // pad it to ensure length remains constant
    if (count($array) < $cols)
    {
      $array = array_pad($array,$cols,$pad);
    }
    // pad the array with a null character as required
    foreach($array as $key => $value)
    {
      $array[$key] = array_pad($value,$rows,null);
    }
    // now inverse the rows with the cols
    foreach($array as $key => $value)
    {
      foreach($value as $sub_key => $sub_value)
      {
        $output[$sub_key][$key] = $sub_value;
      }
    }
    // spit it out
    return $output;
  }
  // oops
  return $array;
}
