PHP Redirect

[dclamp]

I have a PHP page on my domain: http://dclamp.homtek.net/invite.php.

i have it redirect to this page: http://www.rapidfriends.com/join_inv.php?member_id=94 only.

I want it so that some one can put there ID in my domain and have it put it at the end. like this:

They Visit: http://dclamp.homtek.net/invite.php?ID=91

and it redirects to: http://www.rapidfriends.com/join_inv.php?member_id=91

how do i do this?

not sure what you're doing to redirect it, so you'll have to implement this yourself, but it should work fine.

this goes into invite.php:

//this is the base address to redirect to, minus the ID
  $redirect = "http://www.rapidfriends.com/join_inv.php?member_id=";

  if(isset($_GET['id']) && is_numeric($_GET['id'])){
    $redirect .= $_GET['id'];
  }

  //do the redirect stuff now to $redirect 

was that what you were looking for?

also, you might want to put the redirect stuff within the IF statement checking if the ID variable exists and is a number, that way if they open invite.php without '?id=#' in the URL it will do nothing.. or you could just make a default ID for it to redirect to.

Here is what i have. i got it from another Forum:

<?php 
    $id = (isset($_GET['ID'])) ? (int) $_GET['ID'] : 94; 
    header("Location: http://www.rapidfriends.com/join_inv.php?member_id=$id"); 
    echo "<TITLE>Join RapidFriends Network</TITLE>";
    echo "<A HREF='http://www.rapidfriends.com/join_inv.php?member_id=$id'>Click Here If Your Browser Does Not 
        Redirect You</A>";
    exit;
?>

If it does not have an ID number i want it to echo "Please Enter a ID Number" with a textbox and submit button.

how do i do that?

this should work for you.

<?php
  //this is the base address to redirect to, minus the ID 
  $redirect = "http://www.rapidfriends.com/join_inv.php?member_id="; 

  $id = (isset($_GET['id'])) ? $_GET['id'] : "";

  if($id != "" && is_numeric($_GET['id'])){ 
    $redirect .= $_GET['id']; 
//    header("Location: " . $redirect);
    echo '<center><a href="' . $redirect . '">click here</a></center>';
  }else{
    if($id != "" && !is_numeric($id))
      echo "You must enter a numeric value<br><br>\n";
?>
<form method="get">
  ID: <input type="text" name="id"><br><br>
  <input type="submit" value="Submit"
</form>
<? } ?>

I normally like to reserve my header commands for helpful things like sessions, cookies, and cache controls, so, I have developed a way to redirect without headers:

<?
function js_redirect($url="your_url", $seconds=your_time) { 
    echo "<script language=\"JavaScript\">\n"; 
    echo "<!-- hide from old browser\n\n"; 
     
    echo "function redirect() {\n"; 
    echo "window.location = \"" . $url . "\";\n"; 
    echo "}\n\n"; 

    echo "timer = setTimeout('redirect()', '" . ($seconds*1000) . "');\n\n"; 

    echo "-->\n"; 
    echo "</script>\n";

    return true;
}
?>

Just set your seconds and URL at the top of the function, then use it as so:

<?php
js_redirect();
?>

I think now would be the perfect time to unlearn this nonsense. There's absolutely nothing wrong with using header() for redirects. On the contrary, it's the best technique by far, superior to using meta elements in the HTML and infinitely superior to using JavaScript to rewrite the browser URL, which is the most fragile method possible. (Just think of all the browsers with JS disabled.)
