#1062 - Duplicate entry '0' for key 1

[ana1020]

hi,

 

i wrote a php script which is sitting on my server. i also created a table called INQUIRIES using phpMyAdmin. I get no errors when I run my php code, but the INSERT INTO statements do not seem to work. nothing gets inserted into the table INQUIRIES. when i try manually inserting content into the table through phpMyAdmin, i get this error:

 

#1062 - Duplicate entry '0' for key 1

 

did i build my table wrong? what does this error mean? how can i store my $_POST variables in this table without getting an error?

 

the table was built like this :

mysql> create table inquiries (  
    -> inquiries_id int primary key auto_increment not null,
    -> lastname varchar (20) not null,   
    -> firstname varchar (15) not null,   
    -> contactinfo varchar (30) not null,   
    -> subject varchar (50) not null,    
    -> comments blob not null);

 

and my php code looks like this :

 

//CONNECT TO DATABASE				
$dbhost = 'localhost';
$dbuser = 'ana1020';
$dbpass = '86bohuvt23';

$conn = mysql_connect($dbhost, $dbuser, $dbpass) or die ('Error connecting to mysql');				
$dbname = 'fatcat';
mysql_select_db($dbname);

//IF THE SUBMIT BUTTON IS PRESSED, CHECK POST FIELD FOR DATA 		
if (isset($_POST['submit'])) {

//FOR THOSE WHO ENTERED EMAILS ADDRESSES AS THEIR CONTACT INFORMATION	 				
if ((!empty($_POST['firstname'])) && (!empty($_POST['lastname'])) && (!empty($_POST['subject'])) && (!empty($_POST['email'])) && (!empty($_POST['comments']))){
	$firstname = $_POST['firstname']; 
	$lastname = $_POST['lastname']; 
	$subject = $_POST['subject']; 
	$email = $_POST['email']; 
	$comments = $_POST['comments']; 
	$insertdata = "INSERT INTO inquiries (lastname, firstname, contactinfo, subject, comments) VALUES ('$lastname', '$firstname', '$email', '$subject', '$comments')";
	mysql_query($insertdata);

                //FORWARD INFORMATION TO MY PERSONAL EMAIL ACCOUNT
	$to = '[email protected]';
	$subject = $subject;
	$message = $comments . "\n" . $firstname . ' ' . $lastname .  "\n" . $email;
	$headers = 'From: [email protected]' . "\r\n" .
	'Reply-To: ' . $email . "\r\n" .
	'X-Mailer: PHP/' . phpversion();
	mail($to, $subject, $message, $headers);
	print "Thank you for your post<b> $firstname! </b><br />\n";
	print "We will get back to you promptly. <b>";
} 
//FOR THOSE WHO ENTERED PHONE NUMBERS 
elseif ((!empty($_POST['firstname'])) && (!empty($_POST['lastname'])) && (!empty($_POST['subject'])) && (!empty($_POST['phone'])) && (!empty($_POST['comments']))){ 
	$firstname = $_POST['firstname']; 
	$lastname = $_POST['lastname']; 
	$subject = $_POST['subject']; 
	$phone = $_POST['phone']; 
	$comments = $_POST['comments']; 
	$insertdata = "INSERT INTO inquiries (lastname, firstname, contactinfo, subject, comments) VALUES ('$lastname', '$firstname', '$phone', '$subject', '$comments')";
	mysql_query($insertdata);

	//FORWARD INFORMATION TO MY PERSONAL EMAIL ACCOUNT
	$to = '[email protected]';
	$subject = $subject;
	$message = $comments . "\n" . $firstname . ' ' . $lastname . "\n" . $phone;
	$headers = 'From: [email protected]' . "\r\n" .
	'Reply-To: [email protected]' . "\r\n" .
	'X-Mailer: PHP/' . phpversion();
	mail($to, $subject, $message, $headers);
	print "Thank you for your post<b> $firstname! </b><br />\n";
	print "We will get back to you promptly! <b>";
} else { print "Please enter first and last name, a subject and message, and an email or phone number where you can be reached. <br/>";} 					
}

print "</b><br />\n";
mysql_close($conn);

 

 

any thoughts? thanks!!!!

echo your sql string to make sure it contains all your post data you expect it to

 

use mysql_error() after each query to see if any errors occured
