ERROR: headers already sent

HI, I have been through this a couple of times now and I can't see where I am going wrong. I start with a working Data assist Insert and update page, then I follow the steps from the PDF "Adding Digital File Pro to DataAssist Insert and Update Pages" when I upload the file everything seems to work fine but the file is not uploaded, my permissions on the server are correct etc.

I have tried with the beta download also and still come upon the same issue...

when I add the below debug code I get the error placed on the page below

php:

<?php 

error_reporting(E_ALL); 

ini_set('display_errors',on); 

?>

Notice: Use of undefined constant on - assumed 'on' in /usr/home/fuelcd/www/htdocs/fuel09-Manager/jobs_Insert.php on line 3

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /usr/home/fuelcd/www/htdocs/fuel09-Manager/jobs_Insert.php:3) in /usr/home/fuelcd/www/htdocs/fuel09-Manager/WA_DigitalFilePro/HelperPHP.php on line 70

Warning: Cannot modify header information - headers already sent by (output started at /usr/home/fuelcd/www/htdocs/fuel09-Manager/jobs_Insert.php:3) in /usr/home/fuelcd/www/htdocs/fuel09-Manager/jobs_Insert.php on line 154

any help will be greatly appreciated.

cheers
Pete

My guess is that when the error reporting code was added you included a trailing space on the closing php tag, for example:
"?> "

instead of "?>"

a lot of times when the image is not uploading, it is because the form tag does not have the enctype="multipart/form-data" attribute, for example:

html:

<form action="" method="post" enctype="multipart/form-data" id="form1">

no trailing space....
and enctype is and was correct - the form was generated by data assist
I have attached the code that was generated by your software. I would appreciate it if you could take a peek and see why it is breaking

line 3:
ini_set('display_errors',on);

should be:
ini_set('display_errors','on');

Line 5 -7 dont look correct either:
<?php require_once("file:///website/fuel09-Manager/WA_DataAssist/WA_AppBuilder_PHP.php"); ?>
<?php require_once('file:///website/fuel09-Manager/Connections/FuelManagement.php'); ?>
<?php require_once("file:///website/fuel09-Manager/WA_DigitalFilePro/HelperPHP.php"); ?>

they should not have a file reference, it should be a relative path the included files:
<?php require_once("WA_DataAssist/WA_AppBuilder_PHP.php"); ?>
<?php require_once('Connections/FuelManagement.php'); ?>
<?php require_once("WA_DigitalFilePro/HelperPHP.php"); ?>

The only time I have seen the require-once lines use a file reference is if you save as outside of the website and when Dreamweaver asks to update links you answer yes.

should be:

I have made this change.

yep sorry - the links were broken when I did a save as in order to zip the file... I must have clicked yes... it is not like that on the live site, so this is not the problem.

I still get the below error code

Here is a link to the new page with the changes ou requested - attachment.php?attachmentid=343&stc=1&d=1252017607

Thanks for your time.

is it possible for someone to upload a working version of a Data Assist Insert page with a Digital file Pro form field in it. that way I can do some comparisons and see what is breaking. This thing is doing my head

1) That error "Notice: Use of undefined constant on - assumed 'on' " will only occur when there is no single quote around on in the ini_set command:
ini_set('display_errors','on');

Delete the page on the server and reupload to make sure your changes are making it up to the server.

2) I still some some file referances in your file tha twill cause problems and need to be fixed:

<form action="file:///website/fuel09-Manager/jobs_Insert.php" method="post" enctype="multipart/form-data" name="WADAInsertForm" id="WADAInsertForm">

<input type="image" name="Insert" id="Insert" value="Insert" alt="Insert" src="file:///website/fuel09-Manager/WA_DataAssist/images/Slate/Elemental_insert.gif" />

3) For Debugging, temporarily change line 133:
$WA_redirectURL = "jobs_Detail.php";

to:
$WA_redirectURL = "";

so that no redirect will take place.

4) On the bindings panel, expand the WA Global status binding group and bind the debug info binding to the page, this will help us in finding the cause of the problem.
