i have a form that is sending back a "Cannot modify header information"

[studentofstone]

Cannot modify header information - headers already sent by (output started at )  on line 179

I labeled 179 its at the bottom.

I understand this means its already generating the html but not how or where.  A solution would of course be nice but if some one could tell me even how to figure it out it would be great.

MOD EDIT:

 . . . 

BBCode tags added.

[Pikachu2000]

When posting code, please enclose it within the forum's

 . . . 

BBCode tags.

 

Did you read the sticky topic: 'HEADER ERRORS - READ HERE BEFORE POSTING THEM'?

[studentofstone]

First apologies about not nesting. I typed

instead of

.

Yes I read it but it doesn't make sense to me for my application of the header, or I am misunderstanding it.

The code is sending the form data as an email. How would a meta tag work here to redirect?

$headers = 'Subject : '.$about."/r/n"
.'From: '.$email."\r\n"
.'Reply-To: '.$email."\r\n" .
'X-Mailer: PHP/' . phpversion();
header("Location: oht/maintenance/maintenance-report/thank-you/");                              //line 179
@mail($email_to, $email_subject, $email_message, $headers); 

[PFMaBiSmAd]

The error message tells you where the output is occurring at (file and line number) that is preventing the header from working. Since you didn't post that part of the error message, it is not possible for anyone here to directly help you with the problem.

[Pikachu2000]

Post the complete error message, please.

[Pikachu2000]

Is this file included in maintainance.php, or vice versa?

[studentofstone]

oh, I am an idiot. This is, the code I mis- posted is, maintainance.php

[studentofstone]

this is the file the form data is posting to, this is the file that is giving me the error.

[litebearer]

time for a double scotch neat

[studentofstone]

I would like to propose a toast to the crappiest post I have ever made. May there be none crappier.
