php - while 循环没有按预期循环

Question

我有一个循环，它运行 MySQL 查询返回的行并执行命令。

当数据显示在网页上时(在粘贴代码的末尾看到)，requested_date(来自 $result_dec 查询)正确循环，但 memPayout(来自 $emailcompleted 查询)则不然。在显示 memPayout 的地方，它只是列出每个日期的相同数字。

当我在 phpmyadmin 中运行它时，我看到不同的日期有不同的 memPayouts..所以我知道这里有一个错误。

非常感谢您的帮助。

更新:我已使用调整后的新代码更新了旧代码。我尝试用原始的 foreach 包装电子邮件收入查询。我还删除了不必要的额外 bgcolor 开关。我的网页上的结果仍然和以前一样。任何更多的建议真的很感激。

Answer 1

您的代码大致如下所示:

fetch categories
if(categories not empty) {
  foreach(category) {
    set $bgcolor and $userId (has no effect)
  }
  get query results for the last $userID and set $totalEmailEarnAmount1
  if(categories not empty) {
    foreach(category) {
      set $bgcolor again (has no effect)
      generate a div using $totalEmailEarnAmount1
    }
  }
}

由于您在最终 foreach 之外设置了 $totalEmailEarnAmount1 ，它在循环的每次迭代中具有相同的值。

(如果你以与其结构一致的方式缩进代码，这样的错误就会变得明显。凌乱的缩进让你很难看清发生了什么。)
