无法通过php将数据插入mysql表

Question

I'm sure this question has been asked a thousand times but after an hour of truly trying many examples on the web, I have failed to insert new data into my table. I have tried many methods as I said, the one I'm about to post is most recent. If anyone knows why my code is failing it would save so much stress. I have only so far managed to insert data via phpmyadmin. The database is called "test" and the table is called "getting". Please note that "key" is auto incremented.

Thank you

$username='****';
$password='****';
$database='test';



    $con= mysql_connect("localhost",$username,$password);

     mysql_select_db("test",$con);




    mysql_query("INSERT INTO getting (Key, Date, amount, tax, Extra) 
    VALUES ('', 'sept 26 2008', '35653', '46', '454')");

Answer 1

You should try

1. put keywords between backticks
2. format date as YYYY-MM-DD
3. don't use quotes for numbers
4. use NULL for auto-increment keys (you could also remove it from INSERT)
5. perform error checking

Try this query

$res = mysql_query(
    "INSERT INTO getting (`Key`, `Date`, amount, tax, Extra) 
    VALUES (NULL, '2008-09-26', 35653, 46, 454)");
if (!$res) {
    die('Invalid query: ' . mysql_error());
} else  {
    // Do here what you need
}
