【问题描述】：
我想使用 php foreach 或 for 循环在数组数据的 html 表中显示结果。我在下面放置了数组。在数组中有字段'bs_column'，它的值可以是12、6或4。在循环中，如果bs_column等于12和两个，我想在每个tr（每行一列）中显示一个td td 在每个 tr（每行两列）如果 bs_column==6 和三个 td 在每个 tr（每行三列）如果 bs_column==4。
如果未配对 bs_column==6 这是循环序列中的两个字段（<tr><td>field one</td><td>field two</td></tr>），则需要一行中的一列（<tr><td>single field</td></tr>）。
如果没有配对 bs_column==4 这是循环序列中的三个字段 (<tr><td>field one</td><td>field two</td><td>field three</td></tr>)，则将两个字段 (<tr><td>field one</td><td>field two</td></tr>) 配对，如果不配对，则在行中的列中制作单个字段 (<tr><td>single field</td></tr>)。
数组是

【问题讨论】：
-
如果您计划最多有 3 个 td，那么您的所有行都应该有 3 个 td。您需要在需要时使用 COLSPAN 将所有 3 个 td 加入 1 或 2。
-
问题正在打开
<tr>并关闭</tr>。在上面的循环中，当bs_column==6有两行时，它打开<tr>一次并关闭</tr>两次。 -
你的逻辑让我无法理解。我知道您想每行打印 1、2 或 3 个 td。我弄错了吗？在 bs_column==6 部分你测试 $item_count_two == 0，这是真的，所以你插入一个 tr。然后添加 1 个 td 单元格。然后你测试 $item_count_two == $max_six_per_row。由于您从不增加 $item_count_two 我看不出该测试将如何通过，因为 $item_count_two 永远不会等于 2。让我仔细考虑一下。之后我会发布答案。
-
我遇到了一个问题。您的 $fields 数组无效。 PHP 区分大小写，因此数组命令是小写的。我取了第一个条目并将其转换为：'$fields = array(0 => array("id" => 1, "form_id" => 3, "name" => "THE APPLICANT", "slug" = > "customers_the-applicant_heading", "required" => 0, "type" => "heading", "options" => array("field_order" => 0, "bs_column" => 12)));'。这看起来正确吗？我必须从一个有效的数组开始。
-
是的，它是有效的数组。如果您将发布带有建议或上述循环更正的答案，这将很有帮助。谢谢@CharlesEF
