Hi,

I've created a form which allows user input. However, it grabs any < and > and replaces them with &gt; and &lt;, making it tougher to hack. But I still want users to have access to bold text or italic text.

I've thought about preg_matching everything between two tags, for example, everything between *bold* and */bold* will be bold, and everything between *italic and */italic* will be italic. But that takes time, greatly adding to the loading time of the pages.

I don't care about an extra second, but about 5 seconds is too much. Is there a faster way to do this?

Thanks,

just run a replace on BB style code replace [b ] with <b> and [/b ] with </b> etc

Just like this forum does, it adds very very little to load times, microseconds at most.

That would work, yes, but I want to add more features to it that BBCode doesn't have. Sort of like XML, but I don't want to use that either

So far this is what I have:

PHP Code:


$string = "The quick brown fox jumped over the lazy dog.";
$patterns[0] = '/quick/';
$patterns[1] = '/brown/';
$patterns[2] = '/lazy/';
$replacements[0] = 'GIGANTIC';
$replacements[1] = 'yellow';
$replacements[2] = 'stupid';
echo preg_replace($patterns, $replacements, $string); 


And that works, it echoes:
The GIGANTIC yellow dog jumped over the stupid dog
But I want something like this:

PHP Code:


$string = "This is just normal text *italic*but this is italic*/italic*, and *bold*this is bold*/bold* but this isn't.";
$patterns[0] = '/*bold*/';
$patterns[1] = '/*italic*/';
$patterns[3] = '/*/bold*/';
 $patterns[4] = '/*/italic*/';
$replacements[0] = '<b>';
$replacements[1] = '<i>';
$replacements[2] = '</b>';
$replacements[2] = '</i>';
echo preg_replace($patterns, $replacements, $string); 


Which is sort of working...

In my CMS that I built a form of BBCode into but with more options (199 currently) and end users can add their own.

I use a database table with the tags and the replacement markup in it (and a comment that is used as a "prompt").

Then as the content string is streamed out the code loops through the "tags" and if one exists it runs the replace function.
The whole process takes very little time at all
http://www.modtalk.co.uk/article/c-a...gn/dhtml-tabs/ is served out in a little over 2 seconds, and that includes parsing the code elements as which are done with [code ] [/ code] tags as well.

Ah, Regular Expressions. I never got those (how they work).

You have

function _ 
	getElementsByClassName(classname) {
    var a = [];
    var re = new RegExp("\b" + classname + _ 
	"\b");
    var els = document.getElementsByTagName("div");
    for(var i=0;i < els.length; _ 
	i++)
        if(re.test(els[i].className))a.push(els[i]);
    return _ 
	a;
}
show('one');

And right at the line that says

var re = new RegExp("\b" + classname + _ 
"\b");"

It looks like everything surrounded by "/b" will be...?

Bold? IDK.

Can you help me out with RegExps? I think this is what I need!

Thanks a lot!

regular expressions by their nature are "greedy" so if you matched [b at the atart of the string it could match everything in the string upto the LAST [/b.
which is why I don't use them for this kind of thing

Yeah, that what I need. I need (pretty much) my own BBCode, except using tags like (b) and (/b) for my [ and ].

I don't want to install BBCode, because that would take a while for me to implement into my script... I'd post my entire script, but it it gigantic. As you said, "In your CMS", I'm making my own CMS, too.

It's actually not that difficult to create your own. Mind you I did have the advantage of such a thing not actually being available (ASP VbScript), so I had no preconceptions of code or structures that may be required to create such a system. Which of course let me be 100% code creative to build my own efficient (IMO) methods.
