Cannot add header information--- Help me please!!

[wayne186]

Hi, I am trying to use a web based calendar on my site but I am having difficulty getting it running. Whilst the php program that I have seen in demo and live versions does exactly what I want... I can't get around this 'Cannot add header' problem. I am not a php guru and I am really struggling with this, the developer of the calendar does not offer any support by mail, telephone or forum and I'm stuck in a case of 'I want it' but 'it won't work'. The error I receive when going to the default.php page is inserted below:

Warning: Cannot add header information - headers already sent by (output started at /homepages/18/d24357956/htdocs/wayne186/selfbuild/calendar/common.php:328) in /homepages/18/d24357956/htdocs/wayne186/selfbuild/calendar/index.php on line 5

The content of the default.php file is:

<?
require(&quot;common.php&quot;
//
// what view is the default? let's go there
Header(&quot;Location: ./&quot;.$glbl_DefaultView.&quot;.php?LocationID=&quot;.$LocationID);
exit;
?>

From what I can see the default.php file uses common.php for all of the variables ie conections to database, paths and variables. I have also pasted this file below.. I am sorry if this breaches net etiquet by posting the contents of the file, I would absolutley love to get this working and soon as I have a very real and practicle requirement for it. Please e-mail me or post a reply to this thread if you have any thoughts.

Thanks a lot.

content of common.php pasted below (with some obvious removals of passwords and variables).::

Wow, too much code to look at... Simple answer, you cannot send header information after anything else (even a space or a carriage return or line feed) has been sent to the browser window. it looks like it happens first here:

function commonHeader($title) {
?>
<html>

at that HTML tag...

Try reversing the require and Header in default.php...

Well reversing the header and require lines fixed it in that page - but returned this error...

Multiple Choices
The document name you requested (/selfbuild/calendar/.php) could not be found on this server. However, we found documents with names similar to the one you requested.
Available documents:

/selfbuild/calendar/.?LocationID= (common basename)
/selfbuild/calendar/..?LocationID= (common basename)
/selfbuild/calendar/.htaccess?LocationID= (common basename)

I suspect that this is down to the configuration of my common.php file - can anybody advise on the entries I should have for the following entries??

$glbl_UnixPath = &quot;/homepages/18/d24357956/htdocs/wayne186/selfbuild&quot;;
$glbl_WebRoot = &quot;/selfbuild&quot;;
$glbl_AdminRoot = $glbl_WebRoot.&quot;/admin&quot;;
$glbl_WebAdminRoot = $glbl_WebRoot.&quot;/webadmin&quot;;
$glbl_ImagePath = $unixPath.&quot;/imgages&quot;;
$glbl_ImageRoot = $webRoot.&quot;/imgages&quot;;

if I select any of the url's that the above error returns I am returned with a document not found error, so I navigated around and entered a url of a document I do know exists and it gave me another error:

Warning: Cannot add header information - headers already sent by (output started at /homepages/18/d24357956/htdocs/wayne186/selfbuild/calendar/common.php:328) in /homepages/18/d24357956/htdocs/wayne186/selfbuild/calendar/admin/viewConfig.php on line 33

I've applied the same thing to the viewconfig.php file and found the header was after the require again. Seems to be quite a few instances with this in the code. If anybody fancies helping me out to fix the code on this it looks like a really nice calendar and the demo and live versions look really good. If anybody would like to assist me then I would really appreciate it.. you can find the code on the developers site at

http://open.appideas.com/calendar

in the meantime I shall try to work through the one's that I can now that I know to look for the header and require stuff.

cheers for your advice Kevin, much appreciate it..

hmmm... don't think I have the time right now to dedicate to that project, though the demo looks good. Just a general design consideration: I have 800x600 for my resolution and I have to scroll both ways to see the calendar days off to the right and bottom... I'm suree it looks fine on 1024x768, though. If that is a concern for you, then you may want to try to &quot;shrink&quot; the calendar...

[wayne186]

Is there anybody else who is willing to help me on this calendar please?

Kevin, the calendar size can be altered by changing a couple of parameters and altering the 'subject' of an appointments title length will reduce the calendar size to a suitable level. The default is 15 characters but you could reduce it to say 8 andthen when you place your mouse over the title - that column will automatically expand.. pretty cool I think.
