Simple News script using phpbb3 help.

Deathwillow · December 5, 2010

So I've got a simple news script that pulls the last 5 posts in a specific phpbb3 forum but I'm getting errors on the front page whenever they don't at least open the forums before. There errors:

To narrow it down a little more for everyone, When they visit the home page( http://im.deathwillow.com ) before visiting the forums they receive the following errors. Once they have at least visited, not requiring a log in, the forums ( http://im.deathwillow.com/forums ) the errors disappear. Any ideas?

[phpBB Debug] PHP Notice: in file /includes/session.php on line 1024: Cannot modify header information - headers already sent by (output started at /hermes/web03/b36/pow.deathwillow21/IM/index.php:

I guess the simplest way I can think to put it is, some physical (metaphorically speaking) piece of html, text, or information is being output to the browser prior to that script running. Or another session is being called out and started prior to this particular scripts running.

Seeing as you mention its login based. Chances are there's sessions somewhere being implemented in before that script runs.

sessions() have to come before headers and there can only be one session running at the start of the script to the end of the scripts rendering, headers have to come before any kind of codes output.. ie print or echo for example. or even before the

<html>

outputs..

I see in your script its calling to a session of some sort. So maybe a work around to that statement is required

Any ideas?

^^^ Yes, simply read the error messages, they tell you where the output is occurring at that is preventing the header from working. Something at or up to line 8 in index.php is sending output to the browser -

output started at /hermes/web03/b36/pow.deathwillow21/IM/index.php:

You would need to find what is causing that output to be sent before a header statement and eliminate it, assuming it was unintended output or correct the code so that any logic that sends a header is located before you produce and send any output to the browser.

I'm not exactly sure where in the index file this could be happening, here's what it is:

ANY output to browser before starting a session will cause that error. that includes HTML.

Deathwillow · December 5, 2010

So should I place:

<?php include('news.php'); ?>

at the VERY beginning of index.php and use the array function where I need to display the information.

Example of what I mean would be:

<?php include('news.php'); ?>

<html xmlns="http://www.w3.org/1999/xhtml">

<head>
<meta http-equiv="Content-Type" content="text/html; charset=US-ASCII" />

    <link href="main.css" rel="stylesheet" type="text/css" />
    <script type="text/javascript" src="jQuery/jquery.1.4.3.js"></script>
    <script type="text/javascript" src="http://static.wowhead.com/widgets/power.js"></script>
</head>

<body>
    <div id="page">
        <div id="topImage">
            </p> </P>
        </div>
	<div id="navBar">
            <div class="navBar">

                    <li><a href="/downloads">Downloads</a></li>
                </ul>
            </div> 
        </div>
        <div id="content">
            <div id="contentArea">
                <div id="breadCrumb"></div>
                <div id="contentLeft">

                </div>
                <div id="contentRight">
                	<div class="contentRightSetup">
                    	<h1><span class="topic">Currently Recruiting:</span></h1>
                        <ul class="recruitmentList">
                        	<?php include('recruitment.php'); ?>
                        </ul>
                    </div>   
                    <div class="spacer"></div>

                    </div> 
				<div class="spacer"></div>
                    <div class="contentRightSetup">
                    	<h1><span class="topic">Recent Blue Posts:</span></h1>
                        <ul>
                        	<span class="blueFeed">
                        		<?php include('bluePosts.php'); ?>
                            </span>
                        </ul>
                    </div>               
                </div>
            </div>
        </div>
    </div>
</body>
</html>

If i'm understanding you guys right, that should correct it right?

Actually I just went ahead and tried the above and it all seems to work like a charm now, for reference here's the final code.
