kellz Posted November 8, 2007 Share Posted November 8, 2007 I was attempting (AGAIN) to make 1 of those things that stops bots and I think apart from it not working it's a little better lol , well, it half works^^ <?php session_start(); ?> <?php if (isset($_SESSION['correct'])) $correct = $_SESSION['correct']; if (isset($_POST[$correct])) { echo 'you were right!'; } else { echo '...might you be a bot?'; } if ($directory = opendir('pics')) { while(($filename = readdir($directory)) !== false) { if (stristr($filename, ".gif")) { $f_arr[] = $filename; } } closedir($directory); } shuffle($f_arr); $_SESSION['correct'] = substr($f_arr[0], 0, strpos($f_arr[0],'.')); echo '<img src="pics/'.$f_arr[0].'" width="32" height="32" /><br>'; shuffle($f_arr); echo '<form id="form1" name="form1" method="post" action="">'; foreach ($f_arr as $img) { echo '<label>'.substr($img, 0, strpos($img,'.')). '</label><input name="'.substr($img, 0, strpos($img,'.')).'" type="radio" value="radiobutton" />'; } echo '<input type="submit" name="Submit" value="Submit" /></form>'; ?> it keeps saying "...might you be a bot?" before the form is even submit! is it true that PHP can become posessed? so yea.. I run out of idea's, as far as I can see it should be right! :'( I spend all day reading and it only gets me more problems!! ps: please Please PLEASE dont write a new 1 or edit it all to much, I hate getting everything solved for me.. just a little bit is ok to show me where i went wrong.. thanks you!

revraz Posted November 8, 2007 Share Posted November 8, 2007 I don't see where you are even checking Submit: if (isset($_SESSION['correct'])) $correct = $_SESSION['correct']; if (isset($_POST[$correct])) { echo 'you were right!'; } else { echo '...might you be a bot?'; } The first if isset is probably false, so it goes to the second if isset which is false so it echo's Might you be a bot? You need code to check if Submit is set. Link to comment https://forums.phpfreaks.com/topic/76584-solved-huuuh-undefined-session/#findComment-387843 Share on other sites More sharing options...
kellz Posted November 8, 2007 Author Share Posted November 8, 2007 i thought so too and before i posted i tried this: if (isset($_POST['Submit']) && isset($_SESSION['correct'])) $correct = $_SESSION['correct']; if (isset($_POST[$correct])) { echo 'you were right!'; } else { echo '...might you be a bot?'; } } after I posted I tried it like this: if (isset($_POST['Submit'])) { if (isset($_SESSION['correct'])) $correct = $_SESSION['correct']; if (isset($_POST[$correct])) { echo 'you were right!'; } else { echo '...might you be a bot?'; } } And that decided to work... not sure what the big deal was between the both methods.. thanks!
