I have a form with user details and an update statement that will update

  • 0

I have a form with user details and an update statement that will update such details if the user wants to, i added validation so that an email cannot be associated with another account hence the if($checkuser != 0)

The issue with the statement is that if the user doesn’t change their email and updates their details, they will get an error saying email already exist.

I wanted to integrate after the email existence check something like else if(($_POST["myusername"]) == ($row['email'])) then continue updating.(myusername variable name contains the email) meaning that if the posted email is the same as their current email then continue updating.

But i am getting lost, since i am relatively new with PHP i am having trouble with parenthesis and brackets.

Here is my code

if($_POST['usubmit']=='Update') 
{
    $Uerr = array();

    if (!$_POST['fullname'] || !$_POST['myusername']) 
        {   
            $Uerr[] = '» Name or Email must be filled in!';
        }

    if (!checkEmail($_POST['myusername']))
        {
            $Uerr[]='» Your email is not valid!';
        }


    // If there are no errors
    if(!count($Uerr))
        {
            /* Now we will check if username is already in use or not */
           $queryuser=mysql_query("SELECT * FROM customer WHERE email='" . mysql_real_escape_string($_POST["myusername"]) . "'");
           $checkuser=mysql_num_rows($queryuser);

           if($checkuser != 0)
            { 
                $Uerr[]='» Sorry this email is already registered!';
            }

        else 
                {
                    $updateDetails = mysql_query("UPDATE customer SET 
                    name = '" . mysql_real_escape_string($_POST["fullname"]) . "', 
                    dob = '" . mysql_real_escape_string($_POST["dob"]) . "',  
                    address = '" . mysql_real_escape_string($_POST["address"]) . "', 
                    email = '" . mysql_real_escape_string($_POST["myusername"]) . "', 
                    telephone = '" . mysql_real_escape_string($_POST["telephone"]) . "' 
                    WHERE cus_id = '$cus_id'"); 

                    if ($updateDetails) 

                            $_SESSION['Umsg']['Ureg-success']="» Your details have been updated successfully!";

                       else { 
                              $Uerr[]='» error updating your account'.mysql_error(); 
                            }
                }
        }
            if(count($Uerr))
            {
                $_SESSION['Umsg']['Ureg-err'] = implode('<br />',$Uerr);
            }

    header("Location: account.php");
    exit;        
}

    this should work

    if($_POST['usubmit']=='Update') 
{
    $Uerr = array();

    if (!$_POST['fullname'] || !$_POST['myusername']) 
        {   
            $Uerr[] = '&raquo; Name or Email must be filled in!';
        }

    if (!checkEmail($_POST['myusername']))
        {
            $Uerr[]='&raquo; Your email is not valid!';
        }


    // If there are no errors
    if(!count($Uerr))
        {
            /* Now we will check if username is already in use or not */
           $queryuser=mysql_query("SELECT * FROM customer WHERE email='" . mysql_real_escape_string($_POST["myusername"]) . "' AND cus_id !=" . $cus_id(mysql_real_escape_string));

           $checkuser=mysql_num_rows($queryuser);

           if($checkuser != 0)
            { 
                $Uerr[]='&raquo; Sorry this email is already registered!';
            }

        else 
                {
                    $updateDetails = mysql_query("UPDATE customer SET 
                    name = '" . mysql_real_escape_string($_POST["fullname"]) . "', 
                    dob = '" . mysql_real_escape_string($_POST["dob"]) . "',  
                    address = '" . mysql_real_escape_string($_POST["address"]) . "', 
                    email = '" . mysql_real_escape_string($_POST["myusername"]) . "', 
                    telephone = '" . mysql_real_escape_string($_POST["telephone"]) . "' 
                    WHERE cus_id = '$cus_id'"); 

                    if ($updateDetails) 

                            $_SESSION['Umsg']['Ureg-success']="&raquo; Your details have been updated successfully!";

                       else { 
                              $Uerr[]='&raquo; error updating your account'.mysql_error(); 
                            }
                }
        }
            if(count($Uerr))
            {
                $_SESSION['Umsg']['Ureg-err'] = implode('<br />',$Uerr);
            }

    header("Location: account.php");
    exit;        
}
