Itemno=$_Post['Itemno'];
Firstname=$_POST['Firstname'];
State=$_POST['State'];
Streetnumber=$_POST['Streetnumber'];
Zipcode=$_POST['Zipcode'];
if (!Null||!Firstname ||!State ||!Streetnumber||!Zipcode){
echo "You have not entered all the required details.<br/>"
."Please go back and try again.";
exit;
}

if (!get_magicquotes_gpc()) {
Itemno=addslashes(Itemno);
Firstname=addslashes(Firstname);
State=addslashes(State);
Streetnumber=addslashes(Streetnumber);
Zipcode=addslashes(Zipcode);
if (mysqli_connect_errno()){
echo "Error: Could not connect to database. Please try again later.";
exit;
}
@$db= new mysqli("http://www.http://customers.freehosting.com", "teeshome_freeestimates", "xxxxxxx");
(Itemno,Firstname,State,Steetnumber,Zipcode);
insert into customers values
(Null,'Firstname','State.','.Streetnumber','Zipcode');

echo $db->affected_rows;
$result= $db->query ($query);

if ($result){
} else {
echo "An error has occured. The item was not added.";

}
$db->close();
?>

Thank you

 

Lol sorry but you ar egoing to have to give more information on that. I ain't gonna be looking through all that line by line. Please give the full error that you get including line numbers.

 

What are you trying to do with that code?

 

I don't know where you learned PHP, but the code is totally wrong from the first line:

       //create short varible name      
         $Itemno=$_Post['Itemno'];                         
         $Firstname=$_POST['Firstname'];
         $State=$_POST['State'];
         $Streetnumber=$_POST['Streetnumber'];
         $Zipcode=$_POST['Zipcode'];  
                    if (!$Itemno||!$Firstname ||!$State ||!$Streetnumber||!$Zipcode){
         echo "You have not entered all the required details.<br/>"
         ."Please go back and try again.";
         exit;
         }
       
       if (!get_magicquotes_gpc()) {
       $Itemno=addslashes($Itemno);
       $Firstname=addslashes($Firstname);
       $State=addslashes($State);
       $Streetnumber=addslashes($Streetnumber);
       $Zipcode=addslashes($Zipcode);
  

PHP:

Itemno isn't a variable, it's a T_STRING. The variable is $Itemno. Etc.
