Pls is something wrong with my code?
im trying to avoid multiple email entries, but the code keeps inserting data with multiple emails.
And whenever i put email as unique in my database, it dosent show anything if the data already exist


<?


if($submit)
{

$name=$_POST[name];
$address=$_POST[address];
$email=$_POST[email];
$phone=$_POST[phone];

$conn=mysql_connect('localhost','name','');
$db=mysql_select_db('family_jo151');
$query1="SELECT * FROM bfs_list WHERE email='.mysql_real_escape_string($_POST[email]) .'";
$result=mysql_query($query1)or die(mysql_error());
$p=mysql_fetch_array($result);






if(empty($name))

Do you have "on duplicate" in your query? If you make the fields unique, you need to add in "<initial query>on duplicate $this = $that, $thisOtherThing = $thatOtherThing";
VictorAkujobi: 8:07pm On Sep 16, 2012
Oh and escape the variables in your query or better yet, use mysqli with prepared statements or even better yet, PDO. You don't want someone stealing your data, or worse, dropping your DB tables

tnks for ur contribution. I finally got a way round it
Re: Is Something Wrong With This Code by Nobody: 8:32am On Oct 04, 2012
I THINK YOU SHOULD GO TO YOUR DATABASE BACKEND AND TWEEK THE EMAIL TABLE TO UNIQUE,OR BETTER STILL CREATE A QUERY THAT CHECK AND REPLY EXISTING EMAIL.
Re: Is Something Wrong With This Code by Nobody: 9:04am On Oct 04, 2012
build a logic to check the database if email exists, if it exists, tell the to get a life
if it doesn't, insert it.
