rarebit Posted September 15, 2007 Share Posted September 15, 2007 This should help inform you: <?php if(isset($_POST['test'])) { echo "passed<br>"; } if ($_POST['test'] == NULL) { echo "something<br>"; } if(empty($_POST['test'])) { echo "pass<br>"; } print "<html><head></head><body>"; print "<form action='test2.php' method='POST'><input type='text' name='test'><input type='submit' value='send'></form>"; print "</body></html>"; ?> Quote Link to comment https://forums.phpfreaks.com/topic/69482-solved-correct-way-to-write-this/#findComment-349111 Share on other sites More sharing options...
