SQL插入不工作在PHP

我被嘗試插入數據在SQL DB使用PHP，但它不工作。告訴我這裏有什麼問題SQL插入不工作在PHP

SQL代碼在這裏

CREATE TABLE `billing` (
    `user_id` int(10) UNSIGNED NOT NULL, 
    `student_name` varchar(9) NOT NULL, 
    `student_roll` varchar(9) NOT NULL, 
    `student_batch_ID` varchar(9) NOT NULL, 
    `students_course` varchar(9) NOT NULL, 
    `students_payble_ammount` varchar(9) NOT NULL, 
    `payment_recived_date` varchar(9) NOT NULL, 
    `ammount_recived_by` varchar(9) NOT NULL 
) ENGINE=MyISAM DEFAULT CHARSET=latin1;

HTML和PHP代碼在這裏所有的

任何人都請回答 –

首先，你沒有引用您的字符串。您的查詢應該是這樣的：

$billing_data_insert = "INSERT INTO `billing` (`student_name`, `student_roll`, `student_batch_id`, `students_course`, `students_payble_ammount`, `payment_recived_date`) VALUES ('$input_student_name', '$input_student_roll', '$input_student_batch', '$input_student_course', '$input_student_payble_ammount', '$input_student_paid_date')";

而第二，您沒有執行查詢。執行這樣的查詢：

mysql_query($billing_data_insert, $billing_db_connection);

這裏的參考：

http://php.net/manual/en/function.mysql-query.php

所以，你的代碼應該是這樣的：

// your code 

$billing_data_insert = "INSERT INTO `billing` (`student_name`, `student_roll`, `student_batch_id`, `students_course`, `students_payble_ammount`, `payment_recived_date`) VALUES ('$input_student_name', '$input_student_roll', '$input_student_batch', '$input_student_course', '$input_student_payble_ammount', '$input_student_paid_date')"; 
if(mysql_query($billing_data_insert, $billing_db_connection)){ 

    // success 

}else{ 

    // failure 

}

旁註：唐不要用mysql_*函數，它們自PHP 5.5起棄用，並在PHP 7.0中完全刪除。改爲使用mysqli或pdo。 And this is why you shouldn't use mysql_* functions。

它不工作。解決錯誤後請評論php代碼 –

解決錯誤後請評論php代碼 –

@GourabMazumder我已更新我的答案。並利用['mysql_error（）']（http://php.net/manual/en/function.mysql-error.php）函數來調試MySQL錯誤。 –

此外，如果您使用mysql_不mysqli_寫

if(mysql_query($billing_data_insert))

不

if(mysql_query($billing_data_insert, $billing_db_connection)){
