如何在相關表中查找值，以及如何在編輯面板中添加下拉菜單？
[英]How to look up a value in a related table, and how to add a drop-down menu to an edit panel?
問題描述
我有一個腳本，該腳本向我顯示來自MySQL表的數據，並可以在其中添加/編輯員工。 有2個表，部門1個，雇員1個。
我的腳本僅從“雇員”表中捕獲數據，但是此表僅顯示部門ID，而不是部門名稱。
現在我想要的是
- 在我的“門戶”中顯示部門名稱而不是ID。
- 我的門戶現在僅顯示一個文本框，但是我想在部門之間添加一個下拉列表（請參閱屏幕截圖以查看門戶外觀）
如何在當前腳本中實現這一目標？ 我有2個文件：index.php和aev.php：

為了回答查找問題，我認為您的課程本身不支持此功能嗎？ 您需要添加功能。 我會做這樣的事情：
/**
* Converts a FK column to a lookup column
*
* @param $columnName The name of the column in the current table
* @param $foreignTable The name of the foreign table
* @param $foreignKey The primary key in the foreign table
* @param $foreignTextColumn The column to use as a lookup
*/
public function declareLookupColumn($columnName, $foreignTable, $foreignKey, $foreignTextColumn)
{
// @todo Store these values in your class, so you can examine
// them when the table is rendered
}
您還需要修改表格渲染代碼。 對於每一列，請查看是否已使用此方法聲明了該列，如果是，則發出SELECT來獲取外部表值。
