i am creating a simple shoutbox which a user can submit a message and his/her name to a database then my messages.php calls the data up.

but in my main_code.php i seem to have a error. i want it so after a user has submitted their message and user name they get redirected back to the main page.

but it comes up with this error.

Fatal error: Call to undefined function redirect() in C:\wamp\www\MintuzProductions\ShoutboxLOUD\main_co de.php on line 16

the code i am using is as followed.

PHP Code:

<?php
if($_POST['submit']) {
$user=$_POST["name"];
$msg=$_POST["msg"];
//Make Sure a name has been submitted.
 if(!(strlen(trim($user)))) $error[]="you must enter your nickname!";
//Make Sure a message has been posted.
 if(!(strlen(trim($msg)))) $error[]="You must post a message!";
//Redirect to main page if the username & message has been filled in.
 if($user='1'.$msg='1')
  redirect('index.php','Your Message Has Been Posted');
   else redirect('index.php','You Did not post a message');
}
?>

also my shoutbox is actually using a inline frame.

i have index.php with the settings.php included though the include() function. then inside my index file i have an inline frame which links to the messages.php but at the same time inside my index file i also have the forms which uses the main_code.php to process the data.

I've never heard of a built in redirect() function, but try this.

header ("Location: index.php");

Right there isn't one...

Just load the message into a URL variable or store in memory if you want it "cleaner"

There is no line 16 in ends at 15 with ?>

Try this...

PHP Code:

<?php
if(isset($_POST['submit'])) {// check if form was submitted
    $user=$_POST["name"];
    $msg=$_POST["msg"];
    //Make Sure name and msg is not empty
     if(empty($_POST['name'])) {
     $error="you must enter your nickname!";

     }elseif(empty($_POST['msg'])) {
     $error="You must post a message!";
     }else{
    
    $error="success";
     }
}//end check if user have submitted the form

//Redirect to main page if the username & message has been filled in.
if($error == 'success'){
header ("Location: index.php");
}else{
header ("Location: index.php?error=$error");
}
?>

On your index.php place this code wherever you want the error to appear if there's error

PHP Code:

print "{$_GET['error']}"; 


Nice clean helpful post there intrinzic!

and now for mine which probally wont be...

ok you could make the function to do that redirect if its a little easier.

PHP Code:

function redirect($pg, $error_msg)
{
header("Location: $pg?error=$error_msg");
} 


with the above if u have that included in the script you (should) be able to use the redirect() how you were

and the first part will be the page, and the second the error message.

you could also use:

PHP Code:

function redirect($pg, $error_msg) 
{
if(!isset($error_msg)
{
header("Location: $pg");
}
else {
header("Location: $pg?error=$error_msg");
}
} 


this second one is a bit more, the first ones a little more generic

This one, checks if you have enterd a second bit, so if u put

PHP Code:

redirect(index.php); 


it should look at it see it isnt set, and do a striaght redirect to that page using header("Location: $pg");

if it looks at it and see you have enterd soemthing else like:

PHP Code:

redirect(index.php, error! something when wrong); 


it should redirect to index.php?error=error! something when wrong

I have not tested this.

But i hope it helps,

Talkupation Apprieciated

thanks, XD the TP just tipped me over the edge into the TOP TEN!! for TP hehe

Did the function work?

it did and didnt. because i am using a inline frame it seemed to of made like 500 different inline frames with in the same frame.

Whaa? o.0

post link i wanna see wha you mean

i cant its on my localhost

hehe im gonna ammed the function

PHP Code:

<?php
function redirect($pg, $error_msg) 
{ #START FUNCTION

if(!isset($error_msg)
{
if(headers_sent())
{
echo "<script type='text/javascript'>location.href='$pg';</script>";
}
else
{
header("Location: $pg");
}

}
else {
 
if(headers_sent())
{
echo "<a script type='text/javascript'>location.href='$pg?error=$error_msg';</script>";
}
else {
header("Location: $pg?error=$error_msg");
}

}
}# END FUNCTION  
?>

i think thats a bit better than before because it should stop any problems, if like any headers are sent it redirects with javascript.

hope it works, i just saw something in one of my scripts and was like yea!
