Don't think there is any easy way to do it with php. Unless I've missed something major in my manual delving, it has nowhere near the text abilities of, say, shell scripting. It's either truncate at a preset character count for convenience, or don't if you want to retain W3C strict compliance.

The only problem with truncation is that it screws the W3C compliance if it happens to trim the message inbetween a pair of tags.

Logs are the easiest and most useful starting point every time. We've all had one, (or more), of those moments in the past of overlooking what seems obvious afterwards.

With regards to the exit, it's more a bypass. If you look at that function, you'll notice that once the message function is called, it terminates itself directly. The calling script can't continue on.

Edit: Think of it as the page that calls the message function is actually calling a separate page, so therefore it no longer has anything to process itself.

Header.php:

$tpl_main = str_replace('<pun_title>', '<h1><span>'.pun_htmlspecialchars($pun_config['o_board_title']).'</span></h1>', $tpl_main);

Once the message function gets called, message(), further processing of that script stops. (I found out the hard way).

Shouldn't be. Register.php is called to deal with whatever parameters are passed to it. Thereby, it will check the o_regs_allow setting before proceeding any further with it's processing on that demo above.

I may be missing the point of that sentence completely, but what then is this check in register.php?

if ($pun_config['o_regs_allow'] == '0')
{
        message($lang_register['No new regs']);
}

At the end of the day, if you're wanting to optimise the hell out of everything, you've got the source code, start optimising. A high level UI will never give you that level of optimisation no matter what friendly, (and rather useless, one might add), messages it gives you.

This is the file include/user/register.php:

<?php

$register_failed = 'The answer you supplied was incorrect. Please try again.';

session_start();
if (!isset($_SESSION['answer']) || $_SESSION['answer'] == '')
{

$number = rand(1, 4); // Alter the second number to match the number of questions.

//---Questions array---//

$questions = array(

'q1' => 'One plus three equals?',
'q2' => 'Two plus four equals?',
'q3' => 'Eight plus eight equals?',
'q4' => 'Three times three equals?'

);

//-----Hints array-----//

$hints = array(

'h1' => 'One less than five',
'h2' => 'One more than five',
'h3' => 'Just under seventeen',
'h4' => 'One shy of ten'

);

//----Answers array----//

$answers = array(

'a1' => 'Four',
'a2' => 'Six',
'a3' => 'Sixteen',
'a4' => 'Nine'

);

$_SESSION['hint'] = $hints[h.$number];
$_SESSION['answer'] = $answers[a.$number];
$_SESSION['question'] = $questions[q.$number];

}

?>

The answers/questions/hints arrays can have as many added to as you like. Just remember to use the same prefix letter in each array:
(q, a, h), with the numbers after the letter rising sequentially.

The register.php file in the root forum directory needs the following:

This first addition is very near the top of the file.

if ($pun_config['o_regs_allow'] == '0')
{
        require_once PUN_ROOT.'header.php';
        message($lang_register['No new regs']);
}

require_once PUN_ROOT.'include/user/register.php'; // This line added

This is the second section in the root register.php file. The bits between the //----// need adding. I've included existing code above/below for placement. I think it goes in the same place as your original code:

        else
        {
                $language = $pun_config['o_default_lang'];
        }

//------------------------------------------------//

                if (isset ($_POST['spamcode']) && $_POST['spamcode'] != '' && $_POST['spamcode'] == $_SESSION['answer'])
                {
                        session_unset();
                        session_destroy();
                }
                else
                {
                        session_unset();
                        session_destroy();
                        message("$register_failed");
                }
        
//------------------------------------------------//

        $timezone = round($_POST['timezone'], 1);
        $save_pass = (!isset($_POST['save_pass']) || $_POST['save_pass'] != '1') ? '0' : '1';

This is the final section in the root register.php file. Again, layout as above, and goes in the same spot, (I think), as your original code:

                                                <input type="text" name="req_email2" size="50" maxlength="50" /><br /></label>
<?php endif; ?>                                 </div>
                                </fieldset>
                        </div>

//----------------------------------------------------//

                        <div class="inform">
                                <fieldset>
                                <legend>Spambot prevention question</legend>
                                        <div class="infldset">
                                                <p><b>Question:</b> <?php echo $_SESSION['question']; ?></p>
                                                <p><b>Hint:</b> <?php echo $_SESSION['hint']; ?></p>
                                                <input method="post" type="text" name="spamcode" size="10" maxlength="10"/><br/>
                                        </div>
                                </fieldset>
                        </div>

//----------------------------------------------------//

                        <div class="inform">
                                <fieldset>
                                        <legend><?php echo $lang_prof_reg['Localisation legend'] ?></legend>

Remember to remove those //----// lines from that last section as they're in a html section of the script. (Or enclode them within php start/end tags if you want to keep them). If you've any probs, give us a shout. I haven't put line numbers in btw because I do have a bad habit of severely altering/rewriting things, so my line numbers might be way out. I tested it around fifteen times with the final version, and it appeared to be behaving as it should. Obviously though, I would suggest giving it a good test on a test server before using it for real.

Have fun,

I did walk into that one didn't I?

Was looking for something to replace the [ New posts ] bit in viewforum.php. Did eventually find reference to this one: ? which gives a bold asterisk type symbol. (I believe it's classed as one of the mathematical symbols in this context).

Cheers,

Matt

This:

It does a referrer check on the validity of, (or severe lack of), your Xhmtl.

Just realised the downnfall of the above method. It does assume you want to echo the output. So, a secondary one like this:

function vsanitise($parseinput)
{
global $db, $lang_common, $lang_forum, $lang_index, $pun_config, $pun_start, $tpl_main;

        $cleanoutput = pun_htmlspecialchars($parseinput);

}

would make two functions that would suit for either cleaning and echoing the input, (example one), or making a variable from the input, (example two), that could be passed to the inscript variable?

Thanks again,

Matt
