$_SERVER['PHP_SELF'] and variables in same form

programming
1

Hi All,

I’ve got a login page that has a form action of $_SERVER[‘PHP_SELF’], so if the password and username are correct, it just goes to the same page (but shows different content).

The page with the form is Downloads_login.php, and I’ve passed a variable with the url to this page:
http://localhost…/Downloads_login.php?client_id=1

I can get to it no problem, but only BEFORE submitting the form. How do I get the variable to carry on to the rest of the page?

I’ve tried hidden and normal textfields and then posted the variable, but I still can’t get it working.

Here is the page:


<html>
<head><title>Your Downloads</title></head>
<body bgcolor=#FFFFFF>

<?php
$client = $_GET['client_id'];
?>

<div align=center>
  <form name="form1" method="post" action="">
    <input type="hidden" name="client_txt" value="<?php echo "$client" ?>">
  </form>
  <TABLE WIDTH=500 BORDER=0 CELLPADDING=0 CELLSPACING=0>
	<TR>
		
      <TD> <IMG SRC='../../Images/header_01.gif' WIDTH=245 HEIGHT=51 ALT=''></TD>

<?php

// Define your username and password

action="" in the form or a hidden element.

On the page that is recieving the id you need to do this:
<?php
if (isset($_GET[‘client_id’])) {
$client = $_GET[‘client_id’];
}else{
$client = false; // or some other false value
}
?>

Some suggestions… You have it a bit wordy. You only need one form and some variable that holds the error message. So when the page is submitted, rather than a long selection of form/error messages, just have one form, with an if statement that checks if there was an error message. Make sense?

Thanks Marble,

I gave it a go with isset and slimming it to one form, but I still get $client = false (I also echoed “Client is not set” to confirm that I was getting a result from the code).

Like I said in my first post, the variable is being sent in the url and I can retrieve it before submitting the form, but not after.

Is there a way to append the variables to the $_SERVER[‘PHP_SELF’]; form action?

THanks for your time already,
C

Did you put the variable in the action of the form?

Example:
action="<?php echo “somepage.php?id=”.$id; ?>"

So that $id variable (lets give it 3) will be passed to itself when you submit the form in a url like this:
somepage.php?id=3

That’s how I pass the variable to the page to begin with - then you have to login to retrieve the page. My form action is: action=’<?php echo $_SERVER[‘PHP_SELF’]; ?>
so how can I append “?id=$id” to this action?

Form variables.

try doing it like this action=’?id=$id’

That basicly will do the same as $_SERVER[‘PHP_SELF’] but with the id :slight_smile:
