query_first_slave() error when trying to use vBulletin API outside of vBulletin

[nvitremi]

Hi,

Since the past two days, the only thing I'm trying to do with vBulletin is to display a login form or a user information box (when the user is logged in) on every pages of the site, including those not in vBulletin. That's it -- nothing fancy. I do not need or want full integration capabilities -- just display a user information box or a login box whether the user is logged in or not.

I followed a tutorial I found on this site (https://vborg.vbsupport.ru/showthread.php?t=98009) and tried to make a page outside of vBulletin's directory and still use vBulletin's API. Even though I followed the instructions to the letter, I can't make a page outside vBulletin. I get the following error message:

Call to a member function query_first_slave() on a non-object in /var/nvisionit/projects/precisionnutrition/www-newcms/forum/includes/functions.php on line 1303

Is there anything I can do to make this thing work once and for all?

Any help will be appreciated. Thanks in advance!

You should post the code so people can see it.

Here it is:

$navbits = array();

print_output($navbar);

// change the line below to contain the name of the actual main output template used in your script
eval('print_output("' . fetch_template('pn_test') . '");');

I also cleared all my cookies for the site, thus I'm no longer logged in. I get different errors in this case:

What are you spitting out though? I see you eval your template pn_test, but nothing is there to go into pn_test - perhaps post that template. Also, I hope you have a closing php tag at the end ("?>")? And, I don't think you need the line "print_output($navbar);"

[nvitremi]

I usually don't put closing tags when I only have PHP code in my file. See "Instruction separation (http://ca.php.net/basic-syntax.instruction-separation)" in PHP documentation.

Execution errs at "global.php". Anything after that is not executed.

I forgot to mention the custom template "pn_test" simply contains "TEST".

[Lynne]

Does it work if you do the following:
// ########################## REQUIRE BACK-END ############################

chdir(/path/to/the/vbulltin/forums);
require_once('./global.php');

[nvitremi]

No. Still the same happens -- no different.

[Paul M]

What version of VB are you running ?

[Lynne]

Um, I just noticed something.... you didn't really create a template that only has the word "TEST" in it, did you? It needs to be html compliant. ie:

$stylevar[htmldoctype]
<html dir="$stylevar[textdirection]" lang="$stylevar[languagecode]">
<head>
<title>$vboptions[bbtitle]</title>
$headinclude
</head>
<body>
$header

$navbar

<table class="tborder" cellpadding="$stylevar[cellpadding]" cellspacing="$stylevar[cellspacing]" border="0" width="100%" align="center">
<tr>
<td class="tcat" colspan="2">Title</td>
</tr>
<tr>
<td class="alt1" colspan="2">Text</td>
</tr>
</table>

$footer
</body>
</html>
Also, as I said, be sure to remove the print_output line.

I really don't see how the following can work:
// ########################## REQUIRE BACK-END ############################
$forumdir = $pnsite->getConfig('forumdir');
chdir($forumdir);
require_once('./global.php');

$pnsite is not even defined at this point.
