Hello everyone i have a little problem over here im making share button so i want to update the database on the column 'isShared' with value 1 so here is my code but it doesnt work, all the time is showing me Already shared ticket!

Here is the code:

if(isset($_POST['share'])) {
    $user = getUserData('kladilnica', 'Username');
    $shared1 = getUserData('kladilnica', 'isShared');
    $sql = "SELECT `isShared` FROM kladilnica WHERE Username='".$user."'";
    $result = $conn->query($sql);
    while($row = $result->fetch_assoc()) {
        $shared = $row["isShared"];
        if($shared == 1){
            echo "<b>Already shared ticket!</b>";
        } else if($shared == 0){
            echo "<b>Ticket shared succesfully.</b>";
        }
    }
}

Btw if someone knows a better way of making share button please tell in the comments i got this solution on my own.. thank you very much :)

    Ok, perhaps this may work - not tested <?php $responseText = ''; //HANDLE POSTED DATA //This really should be done in a separate file //You shouldn't send a form to itself //Send the form to a form handler file and redirect back //Anyway... $user = getUserData('users', 'Username'); if(isset($_POST['share'])) { $ticket_id … Read More

You say you want to update, but you're only doing SELECT (retrieve).

To update:

"UPDATE `kladilnica` SET `isShared` = 1 WHERE `Username`='$user'"

Yes but how can i update when the selection fail ?
And also now giving me error Fatal error: Call to a member function fetch_assoc() on boolean in C:\xampp\htdocs\Upstrey\home.php on line 496
the line 496 is 6th in the code above.

To be honest I'm a bit lost with your thinking. You want to update if 0 but not if 1?

"UPDATE `kladilnica` SET `isShared` = 1 WHERE `Username`='$user' AND `isShared` = 0"

Then just do a num_rows affected count. If 0 - it means either there's no record for that username or isShared was 1 already.

I want to check if the column isShared is equal to 1 and if is not equal to 1 or its 0 than change it to 1

Any other sulutions please ?
Here is how i show the tickets and share button

$user = getUserData('users', 'Username');
        $sql = "SELECT `Uplata`, `Dobivka`, `match1`, `match2`, `match3`, `match4`, `match5`, `match6`, `match7`, `match8`, `match9`, `match10`, `match11`, `match12`, `match13`, `match14`, `match15`, `match16`, `tip1`, `tip2`, `tip3`, `tip4`, `tip5`, `tip6`, `tip7`, `tip8`, `tip9`, `tip10`, `tip11`, `tip12`, `tip13`, `tip14`, `tip15`, `tip16`, `ticket_id`, `isActive`, `isShared` FROM `kladilnica` WHERE `Username`='$user'";
        $result = $conn->query($sql);
        $count = 0;
        $uplata_total = 0;

        if($result === false) {
            echo "<b>Could not connect to database.</b>";
            trigger_error('Wrong SQL: ' . $sql . ' Error: ' . $conn->error, E_USER_ERROR);
        } else {

                echo "<b>You do not have any tickets.</b>";
            } else if($result->num_rows >= 1) {

                while($row = $result->fetch_assoc()) {

Okay so here is my whole code and now it works but i cannot figure out how do i make just to work on the current button with this code its sharing all the tickets...

$user = getUserData('users', 'Username');

I want to check if the column isShared is equal to 1 and if is not equal to 1 or its 0 than change it to 1

This is what my update query does. Have you even bothered trying it?

Any other sulutions please ?

Ok, remind me not to waste my time with you again.

My apologies Stefan - I was feeling really cranky and made wrong assumptions. OK, as recompense, I shall look into it and advise accordingly - I may take a little while. Again please accept my apologies.

hehe no worries it happen sometimes :D btw when i click any Share button its sharing all the tickets so i think its selecting the whole column of tickets.

Ok, perhaps this may work - not tested

                THIS IS A PROBLEM - id='t02' - you may have multiples of
                this - not allowed as each 'id' on a page must be unique -
                you could leave it out or use a class if you are attaching
                CSS or JS to it. class='t02' would work just as well?

                If you add a hidden input you can attach this to the form
                and you then add an identifier.

                <input type="hidden" value="<?= $ticket_id ?>" name="ticket_id" />

                Alternatively, you could just add a button like this:

                <button name="share" value="<?= $ticket_id ?>" type="submit">Share</button>

                You pick up the value from...
                $_POST['share'] (it will be the ticket_id

                Personally, I'd rather the button method. Hidden inputs
                smack of corner-cutting to me. So, I've replaced your
                submit button with a button(submit)
         -->
