Topic: PHP Help needed
Problem:
How can I use echo inside a return command?
I would highly appreciate fast help. Thanks a lot!

Re: PHP Help needed
Try it.
You mean you want to evaluate the echo execution?
You can assign whatever you want to echo into a variable through a function call like this
if($foo = function_call_to_evaluate($foo2)){
echo $foo;
}
Re: PHP Help needed
Could you say that in easy English again, please?

Re: PHP Help needed
The following is my problem:
return 'Welcome <strong>'.$pun_user['username'].'</strong><br />
<a href="login.php?action=out&id='.$pun_user['id'].'">'.$lang_common['Logout'].'</a><br /><br />
'.implode($online,'').'<br />
'.implode($chatonline,'').'<br />
Users: <strong>'. $stats['total_users'].'</strong><br />
Topics: <strong>'.$stats['total_topics'].'</strong><br />
Posts: <strong>'.$stats['total_posts'].'</strong><br />';I want the implode statements somehow expressed with echo (still with implode, though), because this data does not update immediately and with echo it does. I have been playing around with it a lot, but I could not figure out the right syntax.
*bloody beginner*

Re: PHP Help needed
Erm, when you echo out the return of the function ( echo function($yay); ) it'll execute that code...
Re: PHP Help needed
Hey that is a sweet idea. Do I have to do that wherever the function is called?

Re: PHP Help needed
Oops, that would kinda be a problem, since I somehow have to put that in header.php in the following substitution:
$tpl_main = str_replace('<pun_online>','<div class="inbox">'."\n\t\t\t". generate_whosonline()."\n\t\t".'</div>', $tpl_main);generate_whosonline() is the function

Re: PHP Help needed
Ok, I pretty much got that working now.
I created a new function that echos the generate_whosonline function. And now I call the output function from the header.php file. The problem is though, that the output happens at the top of the page, not where it is planned - in the box in the sidebar.

Re: PHP Help needed
The way it was works just fine: the function gets called, and the result is stored wherever <pun_online> is in main.tpl. Then when you open the page it'll appear in the right position.
Re: PHP Help needed
Well, it does not work right. It does not update immediately. When I login, my name does not appear there immediately. I know though, that echo would do it immediately. That is why I tried it that way.

Re: PHP Help needed
Erm, it should update it immediately =/

Re: PHP Help needed
It does not though.
Here is the whole code:
I added that chatonline myself to show on the main page how many people are in my chatroom
function generate_whosonline()
{
global $pun_config, $lang_common, $pun_user, $db;
if ($pun_user['is_guest'])
{
require PUN_ROOT.'lang/'.$pun_user['language'].'/login.php';
return 'Welcome Guest!<br />
Please login.<br />
<form id="login" method="post" action="login.php?action=in" onsubmit="return process_form(this)">
<input type="hidden" name="form_sent" value="1" />
<input type="hidden" name="redirect_url" value="index.php" />
<label><strong>Username</strong><br /><input type="text" name="req_username" size="13" maxlength="25" tabindex="1" /><br /></label>
<label><strong>Password</strong><br /><input type="password" name="req_password" size="13" maxlength="16" tabindex="2" /><br /></label>
<p><a href="register.php" tabindex="4">'.$lang_login['Not registered'].'</a><br /></p>
<p><a href="login.php?action=forget" tabindex="5">'.$lang_login['Forgotten pass'].'</a></p>
<p><input type="submit" name="login" value="Login" tabindex="3" /></p>
</form>';
}
else

}Here is the other function:
//
// Generate the generate_whosonline() output content
//
function output_whosonline()
{
echo generate_whosonline();

Re: PHP Help needed
I figured it out - pretty much. It is because of the forum main page. It is the only page where the people that are logged in don't show up. Not even after I update it 50 times!
@elbekko: Could I send you the questionable file so that you could look through it. It is not even really long.
Thanks for all the help.
