Hi I did a registration form and I want that when the user have error when they submit the form that another window open with the errors over there and the main one with the registration form so they can modify theirs errors.

I now I can redirect with

header ("Location: test.php");

but I try to do the target in the location and I didn't make it work

Thanks

You're going to have to give us way more information(and show us some code probably), before we can do anything to help.

How did it not work? What happened instead?

Did Location have any effect at all? Did you get any error messages(if so what were they)?

I understand you have a page, where they get a form, they fill it in. it is submitted to ANOTHER(different) page, The other page checks for errors, and should send it back to the first page if there are any, and if not continue on with it's jobs.

Is this understanding accurate?

PS, you will probably have to pass some params(or set cookies - params are better) to the script you are relocating them to, to pass on what errors they made.

add in exit after your header(); as you dont want to process any more html or php after it.
and make sure you don't output anything prior to it either, like headers.

header("location: index.php");
exit;


e.g. Try this and use REFRESH and back and forward. You dont get the "resend form" message.

index.php
--------------------
<?php

if(sizeof($_POST)>0)
{
  // process post
  header("location: index.php?done=true");
  exit;
}
if($_GET="true")
{
   echo "done";
}
else
{
?>
<h3>my form</h3>
<form name="myform" method="post" action="index.php">
<input........
.....
</form>

<?php
}
?>
-----------------------

I should read the questions better.

With mine you could validate and redo the form with the errors listed.

$error=array();
if(empty($_POST['cust_name']))
{
  $error['cust_name']="You must fill this in";

}
if( (sizeof($_POST)>0) && (sizeof($error)==0) )
{
  // process it with no errors
}
else
{
  // display form

.
.
<input name="cust_name" value="<?php echo $_POST['cust_name']; ?>" />
<?php echo $error['cust_name']; ?>
.
.

}
?>

I think waygood's comment will be very helpful to you, and I would recommend that it would be more useful to return the form with the problems labelled than to open another window with this information in.  If you do want to open another window with this information in, you would be better off using javascript.  I can post an example if you still want to do it this way

Good luck!

call ob_start() at the very beginning of your page, and then your call to header() will work.

AFAIK if you want to open it in a new small page, you'll have to use JS.

If it was a hyperlink, you could use the target atribute, but I can't really see how to do wit with headers.

You have to do a post to a test page let's say testcode.php then if everything is okay (after all those ifs and stuff) you do a header to another page like

the code to post it to a new page in Javascript in full mode is

 <SCRIPT LANGUAGE="JavaScript">

function Start(page) {
OpenWin = this.open(page, "CtrlWindow", "toolbar=yes,menubar=yes,location=yes,scrollbars=yes,resizable=yes");
}
</SCRIPT>

THE BUTTON IS

<input type=button value="CLICK HERE" onclick="Start('testcode.php');">

<?
//testcode.php
if blah blah blah

else{

header ("Location: aproved.php")
}

?>

You should target your FORM in a new window, so
- if you've got errors, it will appear in your new windows
- if no error, your new windows should (that's your work) modify its opener (change its location) and close itself.
