PHP垂直交替显示单元格颜色
[英]PHP alternating cell colors vertically
问题描述
I am trying to show a table that shows different packages for membership and need to try to get each column to alternate colors to separate the packages. 
我正在尝试显示一个表格，该表格显示了不同的会员资格软件包，并且需要尝试使每一列具有其他颜色以分隔软件包。 I have the code for alternating cells but they are doing them horizontal and not vertically. 我有交替单元格的代码，但是它们在水平而不是垂直方向上执行。 Please let me know if this is possible and where I have my code wrong to alternate the cells vertically. 请让我知道这是否可行，以及我的代码在哪里错误以垂直替换单元格。 Thank you 谢谢

ok cracks knuckles , lets try this: remove the (array) from the foreach statements, you don't need it. 确定裂缝的指关节 ，让我们试试这个：删除从在foreach语句（阵列），你不需要它。 Also, the $i %2 != 0, you don't need all that, just use $i %2, it is either true or false, so if($i %2) will either be true or false, you don't need the != 0. Instead of having two different $rowstyles, just have 2 of them setup in your CSS, and use a php short if to pick which one to use, like this 此外，$ i％2！= 0，您不需要所有这些，只需使用$ i％2，它为true或false，所以if（$ i％2）为true或false时，您不需要不需要！=0。与其使用两个不同的$ rowstyles，不如在CSS中设置其中两个，并使用php short来选择要使用的php，例如
($i %2 ? 'style1' : 'style2')
and put it in your table cell like this: 并将其放在您的表格单元格中，如下所示：
<td style="($i %2 ? 'style1' : 'style2')">
That will alternate the styles depending on whether your $i is even or odd. 这将根据您的$ i是偶数还是奇数来替换样式。 You also need to make sure that your $i is reset to 0 at the beginning of each row, since you are alternating column colors, you want the rows to all start with 0 so they line up correctly. 您还需要确保在每行的开头将$ i重置为0，因为您要交替使用列颜色，所以您希望所有行都从0开始，以便它们正确对齐。 You don't need to track the rows with a $i, since you don't care what color they are and are only concerned with columns, just make sure to reset $i to 0 every time you start a new table row. 您不需要跟踪带有$ i的行，因为您不在乎它们是什么颜色，并且只关心列，因此只需确保每次启动新表行时都将$ i重置为0。

You are using $i two times in two nested loops, which is bound to fail. 您在两个嵌套循环中两次使用$i ，注定会失败。 Also try to reset it before the second foreach loop. 也尝试在第二个foreach循环之前将其重置。
