The $mail doesn't even come from the form. Should you code it something like:

if(isset($_GET['submit']) && isset($_GET['q']) && isset($_GET['email']) {
    $mail=$_GET['email']; // sanitize this first
    ...

Then the question is what type the email field is.

And a side note: vlidate and sanitize the data from the form before you save it into the database.

again error... no changed?

<?php
    if(isset($_GET['submit']) && isset($_GET['q']) && isset($_GET['email'])){

       $mail=filter_input(INPUT_GET,'email',FILTER_SANITIZE_SPECIAL_CHARS);
       $answer=$_GET['q'];
       $hid=$_GET['hid'];
       $mail=$_GET['email'] ;
            //echo($mail)."<br>";
           //if($row=($sql->num_rows()>1)){
       $sqlu="UPDATE atab
       SET
       email=$mail,
       $answer=$answer+1
        WHERE Qid=$hid";
       $result=$conn->query($sqlu);
       if ($result){
           echo("user has voted");}
       else {
         echo("Error") ;
       }

                }


    ?>

if i enter any number it works but if i enter email or any charector it shows "Error" what to do?

Stick this code on line 3 just after the if(isset($_GET['submit']) && isset($_GET['q']) && isset($_GET['email'])){ line:

die(print_r($_GET, 1));

That will print out the values sent from the form and stop the script. Post the output here.

Enter your Email address:<input type="text" name="email" value="<?php echo $rowa['email'];} ?>" /> <br></br>

Line 47, are you supposed to have } at the end of ;?

Member Avatar for zebnoon1

Mr.Tywan,

} of line 47  began from line 37 while loop......
Member Avatar for zebnoon1

dear broj1,
here is output

Array ( [q] => AnsB [hid] => 17 [email] => zebnoooon@gmail.com [submit] => Submit )

yes this data is from previous form .now what to do?

Member Avatar for broj1

The $_GET array contents is OK. You are getting the email address through. After filtering/sanitizing it the email should not change. It should be writen OK into the database.

Ups, only now I have spotted it. You are missing quotes arround the $mail in your query, like this:

$sqlu="UPDATE atab
SET
email='$mail',
$answer=$answer+1
WHERE Qid=$hid";
