如何解決錯誤「SQLSTATE [HY093]：無效的參數號：綁定變量的數量與令牌的數量不匹配」？

我認爲這段代碼是正確的，但它不能正常工作。如何解決錯誤「SQLSTATE [HY093]：無效的參數號：綁定變量的數量與令牌的數量不匹配」？

我正在嘗試更新數據，但輸出錯誤。我認爲這個問題是綁定時看到的，我的猜測可能是錯誤的！

錯誤

SQLSTATE [HY093]：無效的參數編號：綁定變量的數量不符令牌

問題是什麼數？

'USER_ID =使用：user_id'我想這行一個問題..你通過user_id？ –

像錯誤說你只是沒有相同數量的綁定參數，你會錯過：userid – MacBooc

你也不能重複使用佔位符，但是爲什麼你不想改變'user_id'，不知道。 –

請檢查下面點

1）您沒有綁定user_id。

2）user_photo=:upic, // missing comma

3）user_address=:uadddress, // typo ddd

您沒有在功能上添加USER_ID因此，需要補充的是，那麼在bindparam
