Mambo and G2 embedding

grtz,

Hello,

I have one great looking site until I hit gallery and there are these errors at the top:

Warning: Cannot modify header information - headers already sent in /srv/www/htdocs/Mambo/index.php on line 214

Warning: Cannot modify header information - headers already sent in /srv/www/htdocs/Mambo/index.php on line 215

Warning: Cannot modify header information - headers already sent in /srv/www/htdocs/Mambo/index.php on line 216

Warning: Cannot modify header information - headers already sent in /srv/www/htdocs/Mambo/index.php on line 217

Warning: Cannot modify header information - headers already sent in /srv/www/htdocs/Mambo/index.php on line 218

Has this issue been solved?

Almost forgot:

Gallery version = 2.0-beta-3+ core 0.9.31
PHP version = 4.3.10 apache2handler
Webserver = Apache/2.0.53 (Linux/SUSE)
Database = mysql 4.1.10a
Toolkits = ArchiveUpload, Exif, Gd, ImageMagick, NetPBM, Thumbnail

Thank you,

I sent you a pm with my site and user info just in case.

I don't know if this helps or not, but all the modules work with gallery2 except the SWmenu free. On the gallery component I can see the title of the SWmenuFree block but I can't see any menu choices. This happens only on the gallery component.

kdizzle,

Hi,
i think i found the problem, i think it are mac returns you are seeing in the file, and they aren't correctly read or something.
Could you post a screenshot?

i'll look if i can some how change this setting to use common returns when saving insteas of the apple's returns.

Regards,
Michiel

I see the same things in my copy. Basically ^M characters all over the place. I used dos2unix to convert them but the problem persists.

I'm pretty sure it is that gallery is sending header info and so is mambo.....only problem is I'm too new to PHP to understand how to fix it....

Hi guys, I'm new to Mambo, so I'm not sure of the impacts of this.
But it seems that the reason of the problem is that both Mambo and Gallery send headers.

The problem I found comes from Mambo : Mambo sends its own headers after calling the embedded component.

Have a look at the file index.php at the root of your Mambo installation.
The headers between lines 194 and 198 :

header( 'Expires: Mon, 26 Jul 1997 05:00:00 GMT' );
header( 'Last-Modified: ' . gmdate( 'D, d M Y H:i:s' ) . ' GMT' );
header( 'Cache-Control: no-store, no-cache, must-revalidate' );
header( 'Cache-Control: post-check=0, pre-check=0', false );
header( 'Pragma: no-cache' );

sould be sent before the block that is just before, between lines 177 and 190 :

ob_start();
if ($path = $mainframe->getPath( 'front' )) {
	$task = mosGetParam( $_REQUEST, 'task', '' );
	$ret = mosMenuCheck( $Itemid, $option, $task, $gid );
	if ($ret) {
		require_once( $path );
	} else {
		mosNotAuth();
	}
} else {
	echo _NOT_EXIST;
}
$_MOS_OPTION['buffer'] = ob_get_contents();
ob_end_clean();

Hope this will help.
Now one should open that issue on the Mambo devlist.
If someone is more aware than me of Mambo, maybe he could follow up that fix.

jeff260z, phpsurf, kdizzle,

is there a line with "output started at ..." with these warnings?

please post this also? Only in embedded or also in standalone?

regards,
Michiel

tassos,

i have full report on, and i don't recieve the warnings.

regards,
michiel

No

I only receive the errors in embed mode and only when the gallery 2 componnent.

I do not have gzip enabled.

I tried it both ways.

I just did s cvs update to:

 Gallery version = 2.0-beta-4 core 0.9.32
PHP version = 4.3.10 apache2handler
Webserver = Apache/2.0.53 (Linux/SUSE)
Database = mysql 4.1.10a
Toolkits = ArchiveUpload, Exif, Gd, ImageMagick, NetPBM, Thumbnail
Operating system = Linux apbio 2.6.11.4-21.7-default #1 Thu Jun 2 14:23:14 UTC 2005 x86_64
Browser = Mozilla/5.0 (Windows; U; Win98; en-US; rv:1.7.8) Gecko/20050511 Firefox/1.0.4 

When I turn on maximum error reporting I get the in the component

Notice: Undefined index: id.rootAlbum in /srv/www/htdocs/Mambo/components/com_gallery2/userfuncs.php on line 343

In the random image module I get this

Notice: Use of undefined constant randomImage - assumed 'randomImage' in /srv/www/htdocs/Mambo/modules/mod_gallery_block.php on line 48

I have no idea if these errors mean anything I am just trying to be thorough in my explanation.

The only other strange thing is the way that the module " SWmenuFree" does not appear when the gellery2 com is in use. I can see the title of the block but none of the menus.

edit **I just noticed I mentioned the menu issue before.**

nope...I'm on Slackware 10.1 and I get the issue. I also have gzip enabled.

I got rid of the error by setting display_errors = Off in php.ini and restarting apache but I know that the error is still there and that isn't a permanent fix....

There are no other lines of code displayed. These are the only lines shown. This only happens with the componant displayed. Things work correctly otherwise. It's just that this code is displayed in the mambo header when accessing the componant.

I made the change and the only line I get is:

blisswhisper,

the only one i can think of that belongs to gallery2 and his component is " text/html charset=UTF-8"

the rest isn't set by gallery2 or his component!

strange thing, waiting for other to report.

Michiel

I'm having the exact same problem as kdizzle.

Here is mine:

Array ( [X-Powered-By] => PHP/4.3.10 [Connection] => close [Transfer-Encoding] => chunked [Content-Type] => text/html; charset=UTF-8 )

Thanks! Let me know if I can provide any other info.

you can fix this with a simple perl command (dos2unix won't fix the problem because as opposed to having a carriage return + a line feed (the former of which would be removed by dos2unix) the scripts simply has a carriage return...). Keep in mind that _all_ of the files have this problem. (yay for someone doing their coding in notepad for mac or something!) Anyway, here's how you fix it if you're running a *ux* OS:

perl -e "s/\r/\n/g;" -pi < filename >

Fixing this will not remedy the header error (still seeing that), but it will make it easier to hack around in the code... :D

Thanks Artemido!

I was wondering about the PHP format anomalies myself. After running your perl command I was able to see it in a much more readable format. =)

I was able to fix my problems with the random image block and gallery component by simply commenting out the IF statements where the error messages stated. I'm pretty much clueless when it comes to PHP, but commenting out those lines doesnt' seem to affect the functionality.

I no longer have error messages and everything seems to be working fine. If anyone needs help or have questions what I did let me know. You can also view my 'working' Mambo/Gallery integration at http://tkeeler.webhop.net

Thanks for all your help guys!

p.s. - I wasn't getting the 'cannot modify header information' error message so I'm not sure if this will/wont work for you!

Hi Michiel!

I was getting 2 different errors:

This one was on the random image block:

Notice: Use of undefined constant randomImage - assumed 'randomImage' in /srv/www/htdocs/Mambo/modules/mod_gallery_block.php on line 77

and this one I was getting when I browsed images through the gallery component:

Notice: Undefined index: id.rootAlbum in /srv/www/htdocs/Mambo/components/com_gallery2/userfuncs.php on line 401

When I didn't see a solution in this forum, I went looking through the code to see what I could do. The formatting for the files was all wierd (it looked like it was on 1 single line) so I used artemido's perl command tip to reformat the files:

perl -e "s/\r/\n/g;" -pi < filename >

This didnt' fix the problem but did let me see the code better. I started hacking around - i'm totally clueless when it comes to PHP. This is just a workaround and I wouldn't call it a fix.

Here's the code I commented out:

For the random image block error I commented this out in userfuncs.php:

//if($block == randomImage OR $block == recentImage OR $block == viewedImage OR $block == dailyImage OR $block == weeklyImage OR $block == monthlyImage OR $block == specificItem){
//$css = $itemframe;
//} else {
//$css = $albumframe;
//}

and for the gallery component I commented this out in mod_gallery.block.php:

//      if($g2_Config['id.rootAlbum'] != $item->getId()){
//              $mainframe->AppendPathway($path);
//      }

I have no clue what they do, but it didn't seem to break anything and made the error messages go away.

Maybe you could explain to us what they do and what it might break?

Thanks a million for creating these modules and components - they're great!

Let me know if you have any questions!

p.s. - How did you get the gallery2 stats module on your dev site?

I get these warnings;

Michiel when you say bug is fixed do you mean the header problem? Also which file do I modify? Do I modify line 77 of file mod_gallery_block.php with this code Notice: Undefined index: id.rootAlbum in /srv/www/htdocs/Mambo/components/com_gallery2/userfuncs.php on line 401 ?

jeff260z,

the "Notice: Use of undefined constant randomImage " is fixed

the "id.rootAlbum " i asked you if you installed your gallery2 on a different database?

header, bug is known but i haven't found made fix yet.

regards,
Michiel

buffman,

i haven't fixed the 2 database install, i'm working on it.

regards,
Michiel

I have the last version of Gallery2 integrated with mambo 4.5.2 using the gallery2 component (2.06) and everything works just great.

I have added the gallery2 random image block module and it also works fine, but it creates problem with the text display in Mambo (in news or elsewhere) : all the accentuated characters (my site is in french) disappear and are replaced with question marks. If I remove the image block module everything goes back to normal.

Could not find a solution to this in the forum. Has anybody a clue about what the problem could be ?

regards
