未定義的索引

當我點擊提交它給了我一個錯誤，「未定義的索引：選擇」不知道爲什麼我認爲我做了一切正確的，我使它類似於我連接到數據庫的一些其他頁面精細。選擇是在DB中，我在IF語句中定義它，有人可能會在我的問題上提出一些可能的明顯亮點嗎？未定義的索引

'name =「選擇」'在你的形式？ – Saty

有一個錯誤，所以一切都不正確。也就是說，錯誤所說的是：在表單中沒有名稱選擇的元素。 –

謝謝@Saty甚至沒有意識到一個愚蠢的錯誤。 – Brian

其實，$_POST['selection']您試圖訪問未設置值，並且由於它的投擲Notice: Undefined Index ...

$selection = $_POST['selection'];應該$selection = $_POST['teams'];

<select id="tm1" name="teams">應是<select id="tm1" name="selection">

換句話說，您的表單元素和$_POST數組索引應該保持一致。
