php mysql +插入查詢錯誤

Question

我正在創建一個頁面，用戶可以在其中編輯他們的帳戶並使用php和mysql添加一些文本。首先我能夠插入和更新，但現在它顯示一個錯誤信息關鍵電子郵件地址的重複項 我該如何解決這個問題 這是帳戶設置的代碼，但它不包含任何電子郵件地址字段，所以我會顯示全部是因爲我不知道在哪裏顯示所需的代碼

我編輯的代碼也許這一個是產生錯誤？

Answer 1

它可能會發生，因爲你的用戶表包含已被定義爲在該表中的鍵列EMAIL_ADDRESS列。而且，當你運行該代碼：

$about_query = mysql_query("INSERT INTO user (interest) VALUES ('$aboutme')")or die(mysql_error()); 

，因爲電子郵件地址值沒有給出，它必須指定它會給你一個錯誤。我認爲你不能使用插入查詢這裏改用您已在下面的語句中已經做了更新查詢：

$edit_query = mysql_query("UPDATE user SET first_name= '$fname', last_name= '$lname', address= '$country', specialization_name= '$spec', interest = '$aboutme' WHERE user_id = '$userid'") or die(mysql_error()); 

所以，要麼去除$ about_query或使其更新語句。

Answer 2

使用mysql_fetch_assoc如果你想通過字段名

Answer 3

你好，這是另類索引值：您可以使用：mysql_error（）

if(mysql_insert_id()>0){ 
    //Bla bla bla 
} 
else{ 
    Echo "Mysql Error : ".mysql_error(); 
}
