[riffy]

Hi guys,

How do I redirect a user to another page using PHP?

Header ("Location: " ???

riffy,

You are on to the right function. All you need is to supply the URL:

header("Location: [URL unfurl="true"]http://www.myhost.com/myurl/");[/URL]

Keep in mind that the header statement has to be the first thing sent to the browser. So, no echo(), print() etc. before that or it will fail.

thanks DR

the following is the code to one of the pages on the site i'm working on:

<?
include &quot;config.inc&quot;;
$emailcheck = $email;
$sql = &quot;SELECT * FROM information&quot;;
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
extract($row);

if ($email == $emailcheck) {
  echo '<META HTTP-EQUIV=&quot;Refresh&quot; Content=&quot;0; URL=literature_new.php&quot;>';
  exit;
}
else {
  $email = $emailcheck;
  echo '<META HTTP-EQUIV=&quot;Refresh&quot; Content=&quot;0; URL=request.php?email=\'$email\'&quot;>';
}
?>

basically what the page is doing is checking to see if the email the user entered is already present in the db, if it is, then the page redirects to literature_new.php otherwise it sets the user-entered email as the email value going to be entered into the db and redirects the user to a form where other information can be filled out

my problem is that even for emails already in the db, the code is not working, it keeps processing the else statement and even then it doesn't carry over the email value

thanks
Arif

What is in $row after the fetch? Is the column name called "email" (case sensitive)?

Arif,

Your problem is not with the forward, it is with checking out the records retrieved from the database.

Right now you only compare it to the first retrieved record. You need to loop through all records that the query result contains:

while($row = mysql_fetch_array($result)){
   
   # now send the header if they are equal
   if($row['email'] == $emailcheck){
      header("Location: literature.new.php");
      exit;
    }
}
# if it hasn't been found in the results use alternate header
header("Location: request.php?email=".urlencode($emaicheck));
exit;

That should do the trick.

thanks for all your help guys, however i'm still having trouble...
on another page i have this code

<?
include &quot;config.inc&quot;;
$sql = &quot;SELECT * FROM information&quot;;
$result = mysql_query($sql);
$row = mysql_fetch_array($result);
extract($row);

$referer = &quot;[URL unfurl="true"]http://test.philipslighting.com/nam/events/lightfair/request.php?$email&quot;;[/URL]
$ref1 = &quot;[URL unfurl="true"]http://test.philipslighting.com/nam/events/lightfair/check.php&quot;;[/URL]
	
if (($HTTP_REFERER != $referer) || ($HTTP_REFERER != $ref1)) {
  header (&quot;Location: /nam/events/lightfair/checkemail.php&quot;);
  exit;
}
else {
?>

display page

<? } ?>

for some reason, it is not reading my if statement at all...it's not carrying out the != statement as it automatically goes to the else statement even when my referring page is the one i have specified...

any suggestions??

Are you aware that variable names in PHP are case sensitive?

i know sleipnir

if you are referring to the $HTTP_REFERER variable..it was a typo in my post, i have it as all caps in my code...

 

[sleipnir214]

Have you verified the contents of $HTTP_REFERER?

[riffy]

what do you mean by that? don't we have to set it equal to some value?

 

[sleipnir214]

Instead of assuming that $HTTP_REFERER will has the value you think it does, have you output it to the browser and verified that it does, indeed, contain what you expect?
