Hi Guys

 

Somehow I can't make this chat work... maybe you've got an idea what the problem is?

 

main.php

 

<?php
session_start();
?>
<html>
  <head>
   <title>Chat</title>
    <script language="JavaScript">
    msg = new Array();
    function showchat()
    {
       for (i = 0; i < msg.length; i++)
       {
          show.document.write(msg[i];
          show.document.write("<br />");
       }
       show.document.write("<a name='end'></a>");
    }
    </script>
   </head>
    <frameset rows="0,*,45" border="0">
     <frame name="main" src="main.php">
     <frame name="show" src="show.php">
     <frame name="send" src="send.php" scrolling="no">
    </frameset>
   </html>
   
<?php
   session_start();
   $time = $_SESSION['time'];
   if (!isset($time)) $time = 0;
   $hdlDB = mysql_connect('localhost', 'root', '');
   $strSQL = "SELECT * FROM chat WHERE time > '$curTime'";
   $dhlRS = mysql_db_query('chat', $strSQL, $hdlDB);
   while ($arrRS = mysql_fetch_assoc($hdlRS))
   {
       $arrMsg[] = '<b>' . $arrRS['sender'] . '</b>: '
                         . $arrRS['data'];
       $time = max($arrRS['time'], $time);
   }
   session_register('time');
   
?>
<html>
  <head>
   <title>Chat</title>
    <script language="JavaScript">
     <?php
       if (is_array($arrMsg))
       {
          $i = 0;
          foreach($arrMsg as $strLine)
          {
             echo "top.msg[$i] = '$strLine';\n";
             $I++;
          }
       }
       ?>
       top.show.location.reload();
       </script>
      </head>
       <body onload="window.setInterval('location.reload()', 4000)">
      </body>
     </html>

 

 

send.php

 

<?php
session_start();
if (!isset($time)) $time = 0;
if (strlen($_POST['newmsg'] > 2)
{
   $hdlDB = mysql_connect('localhost', 'root'; '');
   $curTime = time();
   $strSQL = "INSERT INTO chat (time, data, sender)
              VALUES ('$curTime', $newmsg', '$sender')";
    mysql_db_query('chat', $strSQL, $hdlDB);
   session_register('time');
}  /* end if */
?>
<html>
<head>
  <title>Chat</title>
   <script language="JavaScript">
    <?php
    if (is_array($arrMsg))
    {
       foreach($arrMsg as $strLine)
          echo "top.msg[top.msg.length]=\"$strLine\"";
    }
    ?>
    top.show.location.reload();
    </script>
   </head>
    <body bgcolor="white">
     <form action="<?php echo $PHP_SELF; ?>" method="post">
     <select name="sender" size="1">
      <option value="Admin" <?php $sender == 'Admin' ? print 'selected' : print ''; ?>>Admin
      <option value="Client" <?php $sender == 'Client' ? print 'selected' : print ''; ?>>Client
     </select>
     's Beitrag:
     <input type="Text" name="newmsg" size="40">
     <input type="Submit" value="Send">
    </form>
   </body>
  </html>

 

 

show.php

 

<html>
<head>
  <title>Chat</title>
</head>
  <body>
   <script language="JavaScript">
      top.showchat();
   </script>
  </body>
</html>

 

 

Database (chat)

 

CREATE TABLE chat (

      id bigint(20) NOT NULL auto_increment,

      time varchar(10) NOT NULL,

    data text,

    sender varchar(32) DEFAULT '1' NOT NULL,

    PRIMARY KEY (id),

    KEY id (id)

);

 

 

cheers,

You're missing a closing bracket on line 4

 

if (strlen($_POST['newmsg'] > 2)

 

should be

 

if (strlen($_POST['newmsg'] > 2))

 

Syntax errors are usually triggered by something on the previous line. Easy problem to fix when you take a look at the code! Also a good text editor would pick this up for you.
