Please help. Need to parse bbcode in a user profile field and pass it to a template.

I posted a few days ago about this, but a member told me about user profile fields. Very helpful. I've managed to get the profile field to show in the template that I want (member info), however, when I add BBcode or html to the profile field, vbulletin just shows the code in the browser and doesn't parse it.

I know the dangers of html in vbulletin. I'm just trying things to see what works and what doesn't.

So what I need to do is this... I need to be able to show my profile field in the template but have it be parsed. I figure a plugin is needed, but I can't seem to get the code to work. I've read mod about parsing bbcode.

Code:

require_once(DIR . '/includes/class_bbcode.php');

$parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());

$parsed_text = $parser->do_parse($text, $do_html, $do_smilies, $do_bbcode, $do_imgcode, $do_nl2br, $cachable);

I just don't really know where that needs to go for the variable to get "back" to the template. I figure there is an eval() that needs to be there.

I know the template, plugin, and vbulletin "all become one" after the server works, but I can't grasp the concept well.

Please help.

I wrote a mod where I needed to process the bbcode (View all your social group messages) and I copied/modified a function to parse the bbcode:

PHP Code:


		
			
function process_message_preview($message)
{
    global $vbulletin, $vbphrase, $stylevar, $show;

    require_once(DIR . '/includes/class_bbcode.php');
    $bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());

    $previewhtml = '';
    if ($previewmessage = $bbcode_parser->parse($message['pagetext'], 'socialmessage', $message['disablesmilies'] ? 0 : 1))
    {
        $previewhtml = $previewmessage;
    }

    return $previewhtml;
}

The call in the code was something like:

PHP Code:


		
			
query
then
    while ($message = $vbulletin->db->fetch_array($messagelist))
    {
.....
        
        $message['pagetext'] = process_message_preview($message);
eval template that uses $message['pagetext'];
}

So, you look like you are on the right track. You would need to add the call to the function/code prior to the eval statement (like I show above).

Ok I tried to do what you said. I've got a new profile field (field65) that I've managed to display once on my page using an eval statement, but when I try the following code, I get nothing. I've got my variable $mypage inserted into the MEMBERINFO template. I've been playing with this for about an hour now. I must be off to work. Any ideas?

Code:

function process_message_preview($message)

{

    global $vbulletin, $vbphrase, $stylevar, $show;



    require_once(DIR . '/includes/class_bbcode.php');

    $bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());



    $previewhtml = '';

    if ($previewmessage = $bbcode_parser->parse($message['pagetext'], 'socialmessage', $message['disablesmilies'] ? 0 : 1))

    {

        $previewhtml = $previewmessage;

    }



    return $previewhtml;

}  



 process_message_preview($message);



$mypage = process_message_preview($vbulletin->userinfo['field65']);



eval MEMBERINFO;

That is not how you eval a template. Take a look in a page like member.php and you'll see these last lines:

PHP Code:


		
			
eval('$navbar = "' . fetch_template('navbar') . '";');

$templatename = 'MEMBERINFO';

($hook = vBulletinHook::fetch_hook('member_complete')) ? eval($hook) : false;

eval('print_output("' . fetch_template($templatename) . '");');

I got it working! Awesome. Now all I have to do is create a bunch of bbcode tags for html elements like table td tr etc!

heres what I ended up with.

Code:

function process_message_preview($message)

{

    global $vbulletin, $vbphrase, $stylevar, $show;



    require_once(DIR . '/includes/class_bbcode.php');

    $bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());



    $previewhtml = '';

    if ($previewmessage = $bbcode_parser->parse($message, 'socialmessage', $message['disablesmilies'] ? 0 : 1))

    {

        $previewhtml = $previewmessage;

    }



    return $previewhtml;

}  





$mypage = process_message_preview($vbulletin->userinfo['field65']);



eval('$mypage = "' . fetch_template('user_custompage') . '";');

I created a custom template called "user_custompage" and just dumped the $mypage variable in it and nothing else. Works great.

I had posted something saying I was going to go look at class_bbcode.php. I did, and have changed my code to the following...

Code:

function process_message_preview($message)

{

    global $vbulletin, $vbphrase, $stylevar, $show;



    require_once(DIR . '/includes/class_bbcode.php');

    $bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());



    $previewhtml = '';

    if ($previewmessage = $bbcode_parser->do_parse($message, $do_html = true, $do_smilies = true, $do_bbcode = true, $do_imgcode = true, $do_nl2br = true, $cachable = false))

    {

        $previewhtml = $previewmessage;

    }



$mypage = process_message_preview($vbulletin->userinfo['field65']);



eval('$mypage = "' . fetch_template('user_custompage') . '";');

Now what I don't understand is why its not allowing me to use <table> and </table> in my profile field.
Here is my profile field code.

PHP Code:


		
			
<table>



[B]Here is my test page[/B]

[img]https://vborg.vbsupport.ru/external/2009/04/7.gif[/img]



</table>

On MEMBERINFO template, I'm able to show my bold text, the google image, but the <table> tags just show up like text, not html. Any Ideas?

Lynne

<table> is html not bbcode. You would have to parse it for html otherwise it will treat the < and > as text characters and turn them into < and $gt; in the page source.

Risking posting before googling, is there an HTML parse function in vbulletin?

Lynne

04-05-2009 02:10 AM

Probably. You can look in the API for one (link under Quick Links)

Ok that was helpful. I've been looking for the msdn of vbulletin, but I have another question...

If I put some html in a php variable (like $myvar = "<TABLE> STUFF </TABLE>;), then ask it to show on a custom template, it still strips out the chars. Do I need to put a function of some sort on the template itself to allow it to be treated as code and not &lt $gt chars?

Here is a pseudo of what i'm doing...

PLUGIN in global_start:

PHP Code:


		
			
$myvar = "<table> Stuff </table>";

eval $myvar on custom_template;

CUSTOM_TEMPLATE

Code:

$myvar

EDIT: Can I use

(taken from the api)
string unhtmlspecialchars (string $text, [boolean $doUniCode = false])

in a template?

Lynne

You cannot use functions in a template. You may use them in a plugin and then use the result from the plugin in the template.

carcomp

So how do I keep a template from stripping the html out of a php variable when I "eval" it into a template?

Lynne

04-06-2009 03:06 PM

I don't know exactly cuz I've never looked into it. You can take a look at what vb does in the code when you allow html in a forum. It has to parse the message text differently when html is allowed, so go see how they do it with that option enabled.

And here it is, working just like it should. Profile fields as webpages!

PHP Code:


		
			
function process_message_preview($message)

{

    global $vbulletin, $vbphrase, $stylevar, $show;



    require_once(DIR . '/includes/class_bbcode.php');

    $bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());



    $previewhtml = '';

    if ($previewmessage = $bbcode_parser->do_parse($message, $do_html = true, $do_smilies = true, $do_bbcode = true, $do_imgcode = true, $do_nl2br = true, $cachable = false))

    {

        $previewhtml = $previewmessage;



    }

   

    return $previewhtml;

}  



$mypage = unhtmlspecialchars(process_message_preview($vbulletin->userinfo['field65']));



eval('$mypage = "' . fetch_template('user_custompage') . '";');

I'm trying to get certain custom user fields to parse, on postbit_legacy.

I did this plugin in member_complete, but it's still not working. what am I doing wrong?

Quote:

if ($userinfo['field12'])
{
if (!is_object($bbcode_parser))
{
require_once(DIR . '/includes/class_bbcode.php');
$bbcode_parser =& new vB_BbCodeParser($vbulletin, fetch_tag_list());
}
$userinfo['field12'] = $bbcode_parser->parse($userinfo['field12'],0, true);
}
