Yes it is write An example is <?php $string= strpos("monday it rained", 'rained');//missed out a bit. if($string == 1) { echo "there is one instance of the word rained"; } else { echo "the word doesn't exist in the string"; } ?> I have never seen !== false used before, it looks like only part of a statement you have.

Ok, i didn't read it all just added a little bit to the top, <?php ini_set('display_errors', 1); error_reporting(E_ALL); /** * Session.php * * The Session class is meant to simplify the task of keeping * track of logged in users and also guests. * * Written by: Jpmaster77 a.k.a.

As it is obvious you didn't write the code above. If you try php coding you should learn to write your own code, or at least understand the code you have copied. That way you can debug better.

From this code <?php header("content-type: image/gif"); $avatars = array( "http://www.avatarist.com/avatars/Games/Sonic-The-Hedgehog/Sonic-animated.gif", "http://www.avatarist.com/avatars/Games/Sonic-The-Hedgehog/Tails-salutes.gif", "http://www.avatarist.com/avatars/Games/Sonic-The-Hedgehog/Sonic-and-Shadow-transform.gif", "http://www.avatarist.com/avatars/Games/Sonic-The-Hedgehog/Knuckles2.gif"); echo $avatars[rand(0,3)]; ?> I think i am missing one or two headers in here?

Thanks premiso, i can never remeber the ini_set one, and ted if the problem continues post session.php

Hmm, doesn't make sense. White pages will normally mean that there is a critical error (or something) and that it can't show the content , like using a die statement at the beginning of the page. I just noticed that the page content is generated from includes, try using requires instead as they will produce errors then.

He proved me right, lol, maybe you should learn php before you start pretending you know it. He printed the host of your page onto your page, not onto the page in the i-frame like you wanted. Then he printed it from the i-frame onto there page in it. If you asked how to do that then i would of shown you, maybe next time be clearer on what you want.

Not competitive or anything but who's did you use?

This is fixed, and the last time you must learn how to debug, and not post every error here. <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> <title>Geography Trainer Question Tool Panel</title> </head> <body> <table width="950" border="0" cellpadding="0" cellspacing="0"> <tr> <td width="238" height="1"> </td> <td width="335"> </td> <td width="343"> </td> </tr> <tr> <td height="308"> </td> <td valign="top"> <?php $username = "dink87522"; $password = "dinky"; if (isset($_POST['username']) && isset($_POST['password']) && $_POST['username'] == $username && $_POST['password'] == $password) { //hidden ?> <div align="center"><u><strong>Question Tool Panel</strong></u></div> <br /> <strong>Category</strong> <select name="category"> <option>Africa</option> <option>Asia</option> <option>Europe</option> <option>North America</option> <option>Oceania</option> <option>South America</option> </select> <label>User <select name="user"> <option>Eddie</option> </select> <form id="form1" name="form1" method="post" action="process.php"> <label><strong>Question<br /> </strong> <textarea name="question" cols="50"></textarea> </label> <label><strong>Answer</strong><br /> <textarea name="answer" cols="50"></textarea> <br /> <br /> <input type="submit" name="Submit" value="Add question" /> (250 character limit for each text field) <br /> <br /> <div align="center">Copyright 2008 Geography Trainer</div> </form></td> <?php } else { ?> <form method="POST" action=""><div align="center"> <table border="0"> <tr> <td>Username:</td> <td><input type="text" name="username"></td> </tr> <tr> <td>Password:</td> <td><input type="password" name="password"></td> </tr> <tr> <td> </td> <td><input type="submit" name="submit" value="Login"></td> </tr> </table> </div> </form> </table> </body> </html> <?php } ?>

if (isset($_POST['username']) && isset($_POST['password']) && $_POST['username'] == $username && $_POST['password'] == $password) Please read the errors and fix them yourself from now on.

Still arrogant, why do you think people haven't replied because it can't be done in PHP. And you are wrong in programming the phrase "anything can be done when you put your mind to it" is irrelevant, because in programming there are limits to what can be done. So stop being arrogant and accept the fact that PHP can not do it. You are wasting your time.

For christ sake, why don't people ever try and debug on there own. Add or die(mysql_error()); to the statements.

That is outdated now $IPaddress=$REMOTE_ADDR; Should be $IPaddress=$_SERVER['REMOTE_ADDR'];

Are you serious, if it is in your code and you don't know what it does don't post it when you get errors. Google it, use the php manual.

Add error_reporting(E_ALL); to the top of the code in the php ,and then fix the errors or post them here.

You are very arrogant after you have been told it can't be done with php , from people who know what they are talking about you still contradict and tell us that it can. To find out what site someone is coming from use $_SERVER['HTTP_REFERRER'];

First error i saw if (isset($_POST['username']) &&($_POST['username'] == $username && $_POST['password'] == $password)){ should be if (isset($_POST['username']) && isset($_POST['password']) && $_POST['username'] == $username && $_POST['password'] == $password)){//thats how i would do it, also there was a syntax error And please use CODE tags, not QUOTE You also don't close the <?php tag here if (isset($_POST['username']) &&($_POST['username'] == $username && $_POST['password'] == $password)){ //hidden <div align="center"><u><strong>Question Tool Panel</strong></u></div> or reopen it here </td> } else{ ?>

You can use margins, e.g. style="margin-left:100px;" will move it 100px to the right, away from the left

Yep, my bad it is <a href="Javascript:history.back();">Go Back</a>

No it doesn't, although the browser may vary on this. I believe that there may be a problem before this that is aligning the table data. Try <?php echo "<td align='right' style='text-align:right;'>".$getthreads3['showtime']."</td>"; ?>

I just told you, you can't, sorry that is written wrong, it should say you have. The code has done what it should of, which is get the page's host. My only suggestion is having a look at some Javascript, as it may be able to do this, but i am not sure it can. But php can't as far as i know.

OK, that is wierd. This one should <?php echo "<td align='right'>".$getthreads3['showtime']."</td>"; ?> although the array may be causing an error. if so <?php echo "<td align='right'>".$getthreads3[showtime]."</td>"; ?>

Fixed, trying to escape it doesn't work in the code tags. The working one is below. <?php echo "<td align="\right"\>".$getthreads3['showtime']."</td>"; ?>

<?php echo "<td align='right'>".$getthreads3['showtime']."</td>"; ?> I believe this is what you are looking for. Edit: The second set were escaped, but this site seems to remove it in code tags.

That's because xyz.com is the host, and not domain.com. The code will get the host of the page, the i-frame is just displaying the page from another host, not hosting it.
