HTML form submit to PHP -


okay have file called proxy.php these contents , want that, if of forms filled value , submitted, "if" check should become true , run commands have problem , though submit value, doesn't go "if" check. if put commands out of "if" check, start work not inside them.

<html> <body>  <br> <form action="proxy.php" method="post">   <br>  host port 1: <input type="text" name="hport" /> server port 1: <input type="text" name="sport"/> <br> host port 2: <input type="text" name="hport2"/> server port 2: <input type="text" name="sport2"/>  <br>   <input type="submit" /> </form>  </body> </html>   <?php include('net/ssh2.php');    $_post["ip"]="iphere"; $_post["pass"]="passhere";    $ssh = new net_ssh2($_post["ip"]); if (!$ssh->login('root', $_post["pass"])) {     exit('login failed'); }   if($_post['hport1']){  echo $ssh->exec('ls'); echo $ssh->exec('screen -s proxy1 -x quit'); echo $ssh->exec('run these commands'); }  if($_post['hport2']){  echo $ssh->exec('ls'); echo $ssh->exec('screen -s proxy2 -x quit'); echo $ssh->exec('run these commands'); }   echo $ssh->exec('exit');   ?>

the value $_post['hport1'] null because posting 'hport' html. try change. 

if($_post['hport']){         echo $ssh->exec('ls');         echo $ssh->exec('screen -s proxy1 -x quit');         echo $ssh->exec('run these commands'); }

if problem still persists, use isset($_post['hport']) check whether value variable 'hport' set or not. can check post values mannually, use

<?php var_dump($_post); ?>

or

<?php     echo '<pre>' . print_r($_post) . '</pre>'; ?>

for displaying $_post array values in readable format. hope you.
