在 BPM 应用程序中，我试图遍历关联数组的关联数组，并使用 foreach 循环仅返回值 (APP_UID)。但是，我只能显示最后生成的值，而不是所有值。

这是我的代码：

$currentUser = @@USER_LOGGED;
//Copy Notes to Subprocess
$caseId = @@APPLICATION; //Case UID
$subcases = executeQuery("SELECT APP_UID FROM SUB_APPLICATION WHERE APP_PARENT='$caseId'");
if (is_array($subcases) and count($subcases) > 0) { 
  foreach($subcases as $subcase)
  $subCaseId = $subcase["APP_UID"] . ", ";

//Update the Sent By status
executeQuery("UPDATE APP_CACHE_VIEW SET PREVIOUS_USR_UID = '$currentUser' WHERE APP_UID IN ('$subCaseId')");
}

executeQuery 函数应该生成如下所示的 SQL 语句，但事实并非如此。例子：

UPDATE APP_CACHE_VIEW SET PREVIOUS_USR_UID = '54454572356235' WHERE APP_UID IN      
('336545547', '436545534', '736545125')

关于我做错了什么的任何想法？

试试这个。 

    $currentUser = @@USER_LOGGED;
    //Copy Notes to Subprocess
    $caseId = @@APPLICATION; //Case UID
    $subcases = executeQuery("SELECT APP_UID FROM SUB_APPLICATION WHERE APP_PARENT='$caseId'");
    if (is_array($subcases) and count($subcases) > 0) { 
      $subCaseId = '';
      foreach($subcases as $subcase)
      $subCaseId .= $subcase["APP_UID"] . ", ";

    //Update the Sent By status
    executeQuery("UPDATE APP_CACHE_VIEW SET PREVIOUS_USR_UID = '$currentUser' WHERE APP_UID IN ('$subCaseId')");
    }

也不要忘记通过$subCaseId = '';在代码中执行“重新初始化字符串”。

我认为您在这里缺少连接：

在循环顶部初始化变量，如下所示：

$subCaseId = '';

并使用连接运算符.=如下：

$subCaseId .= $subcase["APP_UID"] . ", ";

理想情况下，您还应该从变量中删除最后一个命令和空格$subCaseId

您还需要删除此变量周围的单引号以进行 IN 查询。

请参阅以下完整解决方案：

$currentUser = @@USER_LOGGED;
//Copy Notes to Subprocess
$caseId = @@APPLICATION; //Case UID
$subcases = executeQuery("SELECT APP_UID FROM SUB_APPLICATION WHERE APP_PARENT='$caseId'");
if (is_array($subcases) and count($subcases) > 0) { 
    $subCaseId = '';
      foreach($subcases as $subcase)
          $subCaseId = $subcase["APP_UID"] . ", ";
    //To remove last comma and space
    $subCaseId = substr($subCaseId,0,-2);

//Update the Sent By status
executeQuery("UPDATE APP_CACHE_VIEW SET PREVIOUS_USR_UID = '$currentUser' WHERE APP_UID IN ($subCaseId)");
}

改变

 foreach($subcases as $subcase)
  $subCaseId = $subcase["APP_UID"] . ", ";

到 ：

  $subCaseId = '';
  foreach($subcases as $subcase)
  $subCaseId .= $subcase["APP_UID"] . ", ";

注意串联.=
