Hi everybody,
I wanna make a simple leads form in php, this form has three fields.
the first field is "code", the second one is Name and third is e-mail.
the issue is that i have two tables in my database and i want in one hand store all this information in one table---that's pretty easy...but first I wanna validate the code against another table with some pre-charged codes....the idea is try to make a pre-validation of this codes before the client send the form. I think the best way to do that is with an ajax validation but i can acces the data base through ajax....somebody can help me?
this is my code:
Validation query:
<?php
include("conpb.php");
$sql="SELECT * FROM code_numbers WHERE active=1 AND code_value ='".$_POST['user_name']."'";
//echo $sql;
$result=mysql_query($sql,$conn);
if (!$result) {
echo($query);
die(' Invalid query: ' . mysql_error());
}
$idProm=mysql_fetch_array($result);
//echo $idProm;
$user_name=$_POST['otro'];
if (in_array($user_name, $idProm))
{
//user name is not availble
echo "no";
}
else
{
//user name is available
echo "yes";
}
?>
Form:
<?php
include("conpb.php");
?>
