Header errors

shell4567

I am very new to PHP so I hope I can explain my problem. I am creating a Chinese translation to my companies website. I have created a folder called Chinese and put the classes files as well as the includes file into this folder. The page displays properly, however, I am getting the following errors:

Warning: Cannot modify header information - headers already sent by (output started at /home/upfron2/public_html/Chinese/chineseindex.php:1) in /home/upfron2/public_html/Chinese/classes/class_utils.php on line 369

Here are the lines...367 - 375: Even numbers are BLANK

367 function html_headers() {

369 header( "Cache-Control: max-age=".$this->CACHE_TIME_ALL.", must-revalidate");

371 header( "Last-Modified: ".gmdate("D, d M Y H:i:s", time()-3600)." GMT");

373 header( "Expires: ".gmdate("D, d M Y H:i:s", time()+$this->CACHE_TIME_ALL)." GMT");

375 header( "Content-type:text/html");

I do not understand why I am getting these errors. I am using the same exact includes files for the Spanish and English versions. Any suggestions would be helpful.

Also, my second question. I had a developer create this website so I am still learning about the code. I understand that because this is a warning error it can be hidden on the browser. Where and what code would be needed to do this?

Thanks again for any suggestions

You can not set any headers after output has been started. Make sure no content has been sent to the browser...

Apparently, you are writing something out to the browser in /home/upfron2/public_html/Chinese/chineseindex.php (at line 1 I assume?) You must have that include file statement written out before you call the header function.

You can turn off warnings via the php.ini file. Consult the PHP Manual for more information.

yo Shell, a n00bs best friend is the SEARCH button, located up the top right of this forum, u click it and enter problems u may have and it tells you. Just like thge error you are getting now, i searched and found dozens and dozens of the same things with possible causes.

Here is the first few lines of chineseindex.php

<?
// ====================================\
include("../_dir.php");
$PAGE_TITLE="Complete Grocery Automation";
$PAGE_PICTURE="pic1.jpg";
// ====================================/

$myUtil=new class_utils();
$myUtil->sql_connect();

//----------------------------------------------------------------\
include($ROOT_PATH."includes/all_head.php");
//----------------------------------------------------------------\
?>

bretticus

what's in include("../_dir.php"); or include($ROOT_PATH."includes/all_head.php");

???

Also, when you instantiate $myUtil=new class_utils();
$myUtil->sql_connect(); , is anything written to the browser?

---UPDATE--

You might just try turning on buffering if this gets too problematic...

Here is what is in the _dir.php

<?
// ====================================\
$ROOT_PATH="";
include($ROOT_PATH."classes/init.php");
// ====================================/
?>

Nothing is written to the browser for the other MyUtil...

I have this exact same code used in my english and spanish translations and do not receive this error? Could it be because the page is now in unicode vs western?

bretticus

Geesshh...nested include after nested include! No wonder this is happening 😉 I could be wrong here but I'm going to go out on a limb and say that unicode in a file should have nothing to do as to when the output buffer starts writing to your browser.

Are your Chinese translations substituting dynamically or are they being pulled out of a static file somehow?

I would suggest going through all your nested include files for output (even whitespace before or after <??> delimiters).

Alternately, you can just turn buffering on.

shell4567

Well like I said I didn't develop the site and have a hard time figuring out why there are so many includes.....I figured out a way around this tho....I somehow did the buffering but just had it discard by putting ob_end_clean ( ) which eleminated the header; so then I just put the Header code onto the page directly. Now the header shows up and no errors. I believe all of the includes were for the header (i.e. the logo and menu we have at the top of the screen) then again I am still learning all of this so it gets confusing for me.

So, not sure if this was the best solution but it worked.

Thanks for all your help!!
