mySQL not saving data?

i have a PHP contact form that submits data, and an email...:

<?php 
$dbh=mysql_connect ("localhost", "username", "password") or die ('I cannot connect to the database because: ' . mysql_error());
mysql_select_db ("guest"); 

if (isset($_POST['submit'])) { 

if (!$_POST['name'] | !$_POST['email']) 
{
echo"<div class='error'>Error<br />Please provide your Name and Email Address so we may properly contact you.</div>";
}
else
{
$age = $_POST['age']; 
$name = $_POST['name'];
$gender = $_POST['gender'];
$email = $_POST['email'];
$phone = $_POST['phone'];
$comments = $_POST['comments'];

$query = "INSERT INTO contact_us (age,name,gender,email,phone,comments)
VALUES ('$age','$name','$gender','$email','$phone','$comments')";

mysql_query($query);

mysql_close();

$yoursite = "Mysite ";
$youremail = $email;

$subject = "Website Guest Contact Us Form";
$message = "$name would like you to contact them 
                            Contact PH:  $phone
Email:  $email
Age: $age
Gender: $gender
Comments:  $comments";

$email2 = "[email protected]";

mail($email2, $subject, $message, "From: $email");

echo"<div class='thankyou'>Thank you for contacting us,<br /> we will respond as soon as we can.</div>";

}
}
?>

The email is coming through fine, but the data is not storing the dbase... am i missing something? Its the same script as i use on another contact us page, only difference is instead of parsing the data on teh same page, i now send this data to a "thankyou.php" page... i tried changing $_POST to $_GET but that killed the page... what am i doing wrong?

Check the result from mysql_query(...) to see if it failed or not. If it didn't fail, MySQL should definitely have stored the information for you.

First of all, you must escape your data before injecting them in your SQL query.

This can be done using the mysql_real_escape_string function, like this :

$name = mysql_real_escape_string($_POST['name']);
// ... same for other fields that contain strings
$comments = mysql_real_escape_string($_POST['comments']);

This will ensure that quotes in your data are escaped, and don't mess with the ones that are arround the fields' data in the SQL query, first.

And, second, this will help you prevent SQL Injections.


Also, in case of an error during the execution of a query, [`mysql_query`][3] will return `false` -- which means you should test the value returned by that function -- to possibly log the cause of the error : 
$result = mysql_query($query);
if ($result === false) {
    // An error has occured...
    echo mysql_error();
}

Note : here, I just displayed the error message -- but you should instead log the error somewhere (to a file, for instance), before putting your application to production : your users don't need (nor want) to see any technical error message !
