在这里完成新手，尝试编辑我的第一个PHP代码，非常感谢任何帮助。
我使用this plugin在我的WordPress网站上显示营养标签。在创作者的许可下，我尝试更新从标准垂直格式到horizontal format的显示方式。
我不能为我的生活弄清楚如何在PHP中创建所需的4列表。我在过去的几个小时里用谷歌搜索过，但我发现的一切都是关于调用数据库项目显示为表格。希望这是超级基础，我只是没有正确搜索！
这是我从原始插件文件中编辑的代码;我已经标记了我希望列拆分的位置。

当然，我也可以通过任何非表格的方式让它看起来像横向格式！
真诚感谢任何帮助/指导。
答案 0 :(得分：0)
我认为您可以通过添加
来为每个部分包含一个列div$rtn .= "<div class='column' style='width:25%;float:left;'>\n";
到开头
$rtn .= "</div>\n";
到列分隔符的末尾。这是一个开始的地方。
