Bug in Header line 33

[thecopperhat]

Hey Guys,

 

I'm having some significant issues with my webstore lately unfortunatley the guy I hired to build it turned out to be a flake and I can't seem to track him down to complete his maintenance contract!

 

Anyway the issue I'm having is clients add products to the shopping cart and click check out. That's when this little guy pops up:

 

Warning: Cannot modify header information - headers already sent by (output started at /home/content/82/6334182/html/catalog/includes/application_top.php:1065) in/home/content/82/6334182/html/catalog/includes/functions/general.php on line 33

 

I believe this is the section it's talking about:

 

if ( (ENABLE_SSL == true) && (getenv('HTTPS') == 'on') ) { // We are loading an SSL page

if (substr($url, 0, strlen(HTTP_SERVER)) == HTTP_SERVER) { // NONSSL url

$url = HTTPS_SERVER . substr($url, strlen(HTTP_SERVER)); // Change it to SSL

}

}

 

header('Location: ' . $url);

 

tep_exit();

}

 

////

// Parse the data used in the html tags to ensure the tags will not break

function tep_parse_input_field_data($data, $parse) {

return strtr(trim($data), $parse);

}

 

 

Any help would be greatly appreciated as I'm most basic of basic at this kind of thing. I specialize in what my business does as opposed to how to make the website work lol.

 

Cheers

Brad

Try this in google

 

site:www.oscommerce.com/forums Warning: Cannot modify header information - headers already sent by 33

 

There is a funny character in one of the files on your site that needs to be deleted.

 

HTH

The problem is at application_top.php, around line 1065. I'll guess that's at about the end of the file. Probably there is a blank or other stuff after the last closing ?> . You need to make sure there is nothing after ?> (no blanks, no nothing), as well as no blank lines. Same goes for the beginning of the file (no Byte Order Mark, no blank/empty lines, no blanks/tabs/etc. before <?php).

Found no symbols, spaces etc before <?php . Also cruised to the very last line where I found a bit of white space after ?>. I deleted the extra space however to no avail.

 

I appreciate the help guys, I'm new to this and learning very slowly on top of running the business lol. Oh the joys of the internet.

Also Geoffrey, I searched the aforementioned but wasn't able to understand clearly what I was looking for or supposed to do. I believed the error was directing me to the specific line that the issue was coming from however I haven't got a clue if that line looks funny or not.

[MrPhil]

There are two application_top.php files. Make sure you looked at the right one. Perhaps your editor put more whitespace back into the file after you thought you had removed it? Or, it inserted a Byte Order Mark at the very beginning? Or you failed to properly save the file, so your edit was lost? Or you uploaded to the wrong place? Or your file or directory was "write-protected" ("read-only") so the upload or edit was silently ignored? Lots of things to check there.

What I don't understand is in the "functions" folder under everything, I don't actually have an application_top.php file independent of anything. I'm currently looking at the general.php file as that's where it says the error originates from.

 

Also I'm editing and saving the file directly in the FTP file manager. Not downloading, editing and re uploading. I edit, save and refresh.

hahahahahaha finally. Alright MrPhil you were right. I went digging and found the application_top.php and application_top_old.php files in the includes file no deeper. Both files had excess while space after the ?> . Deleted, saved, refreshed and magically the checkout is working again.

[MrPhil]

Hooray! If you read the error message carefully, you'll see that the error was not really in general.php, but was in application_top.php. application_top.php was outputting text to the browser when it shouldn't have been (which flushes the headers to the browser). When general.php tried to output a header, it was told that the train had already left the station.

More than appreciate the fast awesome answers from forum members!!!! It's a huge help to an untrained "bull in a china shop" web "administrator". lol.

[MrPhil]

osC does not have an application_top_old.php file. That's something left behind by whoever was working on the site. You can keep it around if you want, or eventually erase it once everything is running smoothly for a while and there's no chance you'll want to roll back your site to an earlier state.

 

I mentioned the two application_tops because there is one in catalog/includes/ and another in catalog/admin/includes/. The admin one is used only when you're in admin (store backend), and might have the same problems.
