[PHP] Redirect then error message to user
I'm not quite sure how to get an error message to
print out after a redirect. I know it's possible.
Now page1 moves to page2, check below is on page2
If I leave it on page2 (without redirect), it prints
error to user fine. Once it redirects no print.
I also tried leaving it on form1, at the top it won't
work, since the variables haven't been set yet.
Not sure how to let it post form 1 to form 1 check and
then on success move to form 2.
{
// valid - next -
}
else
{
header(Location: http://www.xx.com/page1.php;
);
print You have errors;
exit;
}
}
?

You either need to carry info about the error in a session variable or
url string or something...above your redirect happens before any error
can be sent to the browser

How *can* you print something out when you've already told the browser to go somewhere else? BTW you ought to have an exit statement after the header() statement, some browsers will get confused if you continue printing stuff after a redirect. -- Jason Wong - Gremlins Associates - www.gremlins.biz Open Source Software Systems Integrators * Web Design Hosting * Internet Intranet Applications Development * -- Search the list archives before you post http://marc.theaimsgroup.com/?l=php-general -- /* Hey, diddle, diddle the overflow pdl To get a little more stack; If that's not enough then you lose it all And have to pop all the way back. */ -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Redirect then error message to user
This isn't working:
Page2 (after page1 has been posted):
else
{
$_SESSION['er'] = 'Please make sure to fill in all 3
corresponding values .';
header(Location:
http://www.x.com/TestMulti4a.php; );
exit;
}
}
Page1:
Opening after session_start
$_SESSION['er'] = $_POST['er'];
Then below in form area:
print $er; (tried also echo)
Am I do something wrong ?

If you want keep changes to any session variables (so that they're available
on subsequent pages) you need to:
session_write_close()
before you redirect.
header(Location:
http://www.x.com/TestMulti4a.php; );
exit;
}
}
Page1:
Opening after session_start
$_SESSION['er'] = $_POST['er'];

What are you trying to do here?
Is 'Page1' == TestMulti4a.php?
Are you trying to display $_SESSION['er'] as set in Page2?
If so why are you assigning $_POST['er'] to $_SESSION['er']? All you need to
do is echo $_SESSION['er'].

Yes Page1 - TestMulti4a
So slightly changed and I thought it was working,
seems TestMulti4a (page1) displays the error when I go
to it directly (before input)
So on Page2 I have:
else
{
$_SESSION['oops'] = Use all 3 fields to set a
skill;
header(Location:
http://www.lurkingforwork.com/TestMulti4a.php; );
exit;
}
Page1:
?php print $_SESSION['oops'] ?
I even logged out of the session, thinking I was now
carrying it through the session.

Re: [PHP] Redirect then error message to user
The only problem I'm having here is that if a user
goes backwards, the error from the session variable
will show up. I put an unset $.. underneath the
echo but that seems to have no effect.

Re: [PHP] Redirect then error message to user
You can pass the error in the redirect URL:
header(Location: http://www.xx.com/page1.php?errmsg=You missed
some stuff)
On your main page you just check if there is an errmsg to be displayed:
if(isset($_GET['errmsg'])) {
echo $_GET['errmsg'];
}
That a simplified version obviously. But that's the concept.
I design all my pages so that one file handles display, edit,
validation and save. Then I don't have to worry about going back and
forth between pages, doing redirects or retaining data through session
variables. Most important, the user doesn't lose what they already
entered just because they missed a field.

Re: [PHP] Redirect then error message to user
Brent - Thank you I will try that method. Can you elaborate more on below. I take it to mean you have one page/script that your pages are going to do all the checks. This form is 5 pages long. So I chose session variables just to keep it neat and maybe, more secure.

RE: [PHP] Redirect then error message to user
I think what Brent is suggesting is a single script that will handle the
display and processing of all 5 form 'pages'. The code below is just to give
an idea of how I think the 'flow' could go, don't go copying the code and
expect anything (positive) to happen !!
if(!$_POST['step'] || $_POST['step']=='0')
{
// Display form 1 or call appropriate function/method
if ($_SESSION['errmsg'])
echo $errmsg;
form action=$PHP_SELF?step=1
}
if($_POST['step']=='1')
{
// Validate form 1 or call appropriate function/method
if (error found) {
$errmsg = ul;
$errmsg .= li Field One is required /li;
// etc etc
$_SESSION['errmsg'] = $errmsg;
}
// Not sure about the following line ??
Header(Location: http://mysite.com/path/to/myself?step=2;);
}
if ($_POST['step']=='2')
{
... etc...
