POST with image not working


Recommended Posts

Hey there,


I'm trying to make a simple point adding system and it works so far, but it works with a submit button and not an image. So if i click the button it will add 20 'points' to the database i provided but this does not seem to work with an image. Can someone help me with this, i'm kinda new to php.






//defining username and amount of points to give + the current points


$username = 'djexploit';

$seepoints = mysql_query("SELECT points FROM members WHERE username='$username'") or die(mysql_error());

$fetchresults = mysql_fetch_row($seepoints);

$currentpoints = $fetchresults['0'];


echo "Current points are: $currentpoints points.";


$points = $currentpoints + 20 ;







$newpoints = $points;

//the updating of the points field

mysql_query("UPDATE `members` SET `points` = '$points' WHERE `username`= '$username'") or die(mysql_error());


echo "The amount of points has been updated. You now have $newpoints";


} else {


echo '<br>click the image to add 20 points';









<form id="form" action="give.php" method="post">

<a href="http://www.google.com"><input type="image" src="http://hamovhotov.com/advertisement/wp-content/uploads/2007/03/468x60ad.gif" name="submit" value="submit"></a>

Ah I see..

I thought that if ($_POST['submit]) meant if it was clicked. I don't know much about javascript although I did hear about OnClick() function. Could that be it? And if so how do i make it so that it posts to php so i can put it in an if statement?

I agree with previous commenters that it would help to know what your link does when you click on it. PLEASE don't use JavaScript. That is a hack.


Try putting the type="submit" attribute on the input. The name attribute gives the element a name, and the value is the actual data you are passing. You should consider reading the API. MDN is better than w3schools.com. They're notoriously wrong.

If this works, please don't forget to mark my answer as the solution. (please)
