I’m having a form with only one submit button. I don’t know why, but when I use this code and I click on the submit button, nothing is happening. If I use a ! before the isset you’ll see the echo in the page. I don’t know what’s wrong with it.
<form>
<input type="submit" value="Toevoegen" name="addImg" />
</form>
<?
if (isset($_POST['addImg'])) {echo "haaallloooo";}
?>
Maybe, form by default is sending variables by get, try using method=”POST” attribute in form tag
