Hello.

How do you create a 'product' plugin file like the one at https://vborg.vbsupport.ru/showthread.php?t=99579

(see the code in Ted S's 'welcome hdr 4 0 6.zip' file download).

In the xml file contained in the zip file, it begins with the tags, '<product...>' then '<templates>', then '<plugins>', etc.

Was this coded by hand or is there a template that is used to create these types of xml files for importing into the vB Plugin system? I see how to create the <plugins> code using the vB Plugin Manager (Download) in AdminCP, but not the rest. I'd like to create a clean file for creating templates via this type of xml so when I create revisions for others, I can make it where they can 'import' the complete xml 'product/plugin' vs. using a 'txt' file download that says, 'Find' this, 'Add' that, etc.

Thanks in advance.

it's coded by hand, I believe..atleast thats how i've coded mine thus far.

You should not code Product/Plugin XML-files by hand. If you set the correct Product everywhere (new templates, phrases, settings,...) it will all be in the file when you export it.

How? Is this done within vB AdminCP? If so, where? How to create e.g. a new template or phrases using the plugin manager (or wherever in vB) without coding by hand? How to '...set the correct Product everywhere...'? What is that?

Thanks in advance.

Hello
I would like to use function.php file in my priavte plugins and I didn't find sutable Hook Location
I need to change this line :
PHP Code:
return $datefunc($format, $timestamp_adjusted); 
with this :
PHP Code:

               $new=$datefunc($format, $timestamp_adjusted);
                $new=preg_replace('/AM/', 'After Morining', $new);
$new=preg_replace('/PM/', 'P - M', $new);

        return  $new; 

HaMaDa4eVeR 02-01-2006 01:13 PM
Is there any 1 can help me here

Cap'n Steve 02-01-2006 07:27 PM
Look in whatever function is contained in $datefunc. If that doesn't work you'll probably need to modify the code.

Marco van Herwaarden 02-01-2006 07:50 PM
Are AM & PM not defined by Phrases? Couldn't you just change the phrase?


EDIT: No it looks like this is not phrased

This quote should be updated:

You can join into Queries now:
Lets say you wanted to show some custom info on each post. In 3.0x you would modify an exsiting query. Its the biggest query in showthread.php. Starts like "$posts = $db->query_read("".

You would have to add you own SELECT statments like table.username AS username, and JOIN statements like LEFT JOIN " . TABLE_PREFIX . "user AS user ON(user.userid = post.userid). You don't need to do that anymore.

If you wanted to do this is 3.5 using hooks you can. Open showthread.php and find around line: 923-924. You should see...

PHP Code:
$hook_query_fields = $hook_query_joins = '';
($hook = vBulletinHook::fetch_hook('showthread_query')) ? eval($hook) : false; 
Under that you will see a very large query, in that query you will notice the variables, $hook_query_fields, and $hook_query_joins. Thats your ticket into this query.

You would simple go into the plugins, add new plugin and write it like so: Plugin Name is "showthread_query"
PHP Code:
$hook_query_fields = ",tablename.rowname AS newname";
$hook_query_joins = "LEFT JOIN " . TABLE_PREFIX . "tablename AS newtable ON(tablename.rowname = post.rowname)"; 
Tips:
Just remember to start "$hook_query_fields" variable with a comma.
You can also add conditions around this which is great I think. Example:
PHP Code:
if ($var == $var2)
{
        $hook_query_fields = ",tablename.rowname AS newname";
        $hook_query_joins = "LEFT JOIN " . TABLE_PREFIX . "tablename AS newtable ON(tablename.rowname = post.rowname)";
} 
Hope this helps some advance users. :)

Help..

I got this part in my plugin:

$guestIC = $vbulletin->options['LaCN_guest_text'];
}


eval('$LaCN_message = "' . fetch_template('LaCN_message') . '";');
in the templates I have this:

Quote:

the template shows.
But $guestIC won't show :(

What's wrong ?

Wired1 05-23-2007 07:50 PM
Re-read the instructions. Your code that calls the hook is wrong, and you need to enter the hook into the xml file that holds the hooks.

LaCN 05-23-2007 08:29 PM
Before I make an xml file, I'm building it first as if it was already installed ;)
The plugin is set in the global_start hook, so that's fine.

the plugin itself has to add the to be used templated to the cache, that's what I've used that eval line for

Can one add hooks in plugins (for add-ons)?
I guess not, but I don't lose anything by asking...

Have you tried it out anyway? I don't really see the point of including a hook in your plugin code if people want to develop modifications for it then they could just edit the plugin code. I guess it is your choice but it wouldn't be something I would do.

In fact, I want to develop a "bridge" for users that have one of my modifications and one I'm planning to release soon. I don't want them to edit the plugin code, because they'll have to do it over and over again on each update.
So hooks would really come in handy here.

Opserty 08-15-2007 11:12 AM
Fair enough, I don't see why that link I posted wouldn't work the same in a plugin. Just do the same but instead of writing the hook in the PHP file stick it in your plugin. No harm in trying if you haven't already done so :p

Did you get some kind of error or was it just not working?

Lea Verou 08-15-2007 11:21 AM
I didn't try it yet, as I didn't need it at the time (I need it today).
I'll try soon though and post what happened.

Is this tutorial current as of vb 3.6.8?

I'm looking for a plugin tutorial and wondered if this is still relavent

Birched 09-21-2007 03:42 PM
The advice by KirbyDE at the end of the main entry was BY FAR the most useful part for me, but yes, I believe it is all still relevant.

Hubbitus 09-24-2007 12:04 PM
At the beginning, thank you for the good basic guide.

But I'm not completely understudying how I can associate my hook with two or more "hookname" at once? E.g. "newreply_post_start", "newthread_post_start".

If I try this code:
Code:
<title>vB Category Icons</title>
<hookname>newreply_post_start</hookname>
<hookname>newthread_post_start</hookname>
I get hook, associated to "useradmin_edit_start", as I understood the first item at the list.

Is it the only way to make the fully copy of the code into a new hook and associate it with new hookname???

Opserty 09-24-2007 03:03 PM
This tutorial is old. You can add plugins through the AdminCP via the Plugin Manager.

I don't think it is possible to associate the same code to two hooks. Just copy the code over to a new plugin to create code for another hook.

Of cause, I known. But, I'm don't known how associate the same code to two hooks in this case too.

If no other, "normal" way, off cause i do that. But I hope that someone will prompt more correct way.

Hi, I just want to display a list of users who have posted on a thread at the top of the thread using the hook system. I'm brand new to VBulletin and was wondering if there is a good tutorial or documentation that would help. I've looked in the vb manual and it just has like 2 pages on writing plugins. Can anyone help?

Is there a way to add WHERE and ORDER statements to this query as well, using hooks?
