wildteen88 Posted August 3, 2006 Share Posted August 3, 2006 You cant without submitting the form. You cannot use PHP like you can with javascript. However you can if you use AJAX.

CTM Posted August 3, 2006 Share Posted August 3, 2006 He could use Javascript alone too, depending on his purpose. Link to comment https://forums.phpfreaks.com/topic/16479-increase-value-by-one/#findComment-68754 Share on other sites More sharing options...
HeyRay2 Posted August 3, 2006 Share Posted August 3, 2006 To have PHP do this, you would have to submit the form and refresh the page each time the button was clicked to increase your counter. You would also have to include the current value of [b]$static[/b] as a hidden element in your form:[code=php:0]<?php// Get the current value of $staticif(isset($_POST['static'])){ $static = $_POST['static'];} else { $static = 0;}// Check if the form was submittedif($_POST['button']){ $static++;}?><html><body><form method="POST" action="<?php echo $_SERVER['PHP_SELF']; ?>"><input type="hidden" name="static" value="<?php echo $static; ?>"><input type="submit" name="button" value="CLICK"></form></body></html>[/code]As already mentioned, another option would be javascript. Create an "OnClick()" event that will increment the variable each time.
