vBulletin CMS Widgets - United-Forum Nivo Slider Widget

Based on the Nivo Slider - all credit for slider awesomeness goes to them.
vB4 implementation goes to me.


What it is:
A slider for cms articles, it gets the articles via database, uses (if possible) the previewimage there and resizes it to slider size *update 1.1.0 cropping function included.

Livedemo on a Big Board (>2.000.000 posts)
the nivo slider on our site is customized to fit our heavily customized cms. Default look of this addon is shown in the picture below

Installation

• upload all files (attached zip file) in the folder where you do need them - this has to be the same folder you will set via $slider_img_filepath (see picture)
  
  
  
• create a new php-widget and insert the following code:
  

  // DEBUG MODUS !
  $debug_modus = false;
  
  if($debug_modus === false)
  {
  	ob_start();
  }
  
  //nivo slider - uf - vb.org version
  //set these values as you need them:
  
  //your slider folder - has to be read and writeable
  //folder where all slider files are saved
  $slider_img_filepath = 'external/unitedforum/slider/';   
  
  //picture width and height !same as in the CSS FILE!
  $maxwidth = 650;                                  
  $maxheight = 250;    
  
  //do you want images without previewimage to be shown? slider is using the fallback then
  $show_articles_without_image = false;           
  
  //picture shown if your articles has no previewpicture
  $fallback_img = $slider_img_filepath . 'uf_fallback_slider.png';  
  
  //hardcoded maximum is 20 - if you want more just ask
  $number_of_articles_shown = 10;                                
              
  //lengh in characters of the article descriptions
  $description_length = 95;
  
  //stretch picture or crop them? false = strechting (default) true = cropping (beta)
  $crop = false;

• set refresh time to something big!
• save - add the widget to your layout - enjoy

Custom settings:

At the top of the php-widget code you can see the following:

// DEBUG MODUS !
$debug_modus = false;

if($debug_modus === false)
{
	ob_start();
}

//nivo slider - uf - vb.org version
//set these values as you need them:

//your slider folder - has to be read and writeable
//folder where all slider files are saved
$slider_img_filepath = 'external/unitedforum/slider/';   

//picture width and height !same as in the CSS FILE!
$maxwidth = 650;                                  
$maxheight = 250;    

//do you want images without previewimage to be shown? slider is using the fallback then
$show_articles_without_image = false;           

//picture shown if your articles has no previewpicture
$fallback_img = $slider_img_filepath . 'uf_fallback_slider.png';  

//hardcoded maximum is 20 - if you want more just ask
$number_of_articles_shown = 5;                                
            
//lengh in characters of the article descriptions
$description_length = 95;

If you change $maxwidth and $maxheight you need to edit the nivo-slider_uf_theme.css file, here:

.theme-uf #slider {
    margin:0px auto 0 auto;
    width:650px; /* Make sure your images are the same size */
    height:250px; /* Make sure your images are the same size */
}

Width and height have to be the same value in your php-widget and in the css file.

In additon to these settings i also included a "value/relevance function". Meaning the slider doesn't show your latest 5 articles, but instead weights them based on age and comments.

As older an article is the less likely it will show up in the slider.
More comments make it more likely.

This behaviour can be easily changed. I didn't include an if condition cause every board has different needs and i don't know whats best for you.
In addition conditions like "articles just from this section - or these sections, or this category, with a minimum of 10 posts" can be included via one single if condition. Again, i don't know what your board needs or what your category names are.

You can also modify the preview length (more words, less words), the preview style (color fontsize, fontweight .... Again different forums different needs. It's highly customizable.

Support:

Support and requests for the slider itself should be asked here http://nivo.dev7studios.com/
Same goes for different slider themes - a lot is possible, even thumbnails - again this is part of the nivo slider and not the vb4 implementation.

If you have any questions regarding the settings - or want different settings (which have to do with vb4) - ask, and i'll try to come up with some code // show you where you have to put what.

Slider not working. No idea why?

You will find a FAQ in the first comment, which will be kept up to date:
FAQ

The widget here is completely free. No charge, no branding.
But, we do not mind donations either. If you want to give us something. Since we are advertising free and fan based we are happy about every small donation.
( On Forumhome bottom right paypal button: http://www.united-forum.de/forum.php )



That's all
Hope it works for you.

Yes I did, it's working fine...
Is your board on local or on the webserver?

webserver..

www.SinfulShadows.com

however when the plugin is loaded it only loads 20% of the time, as the database errors while its half broken so the plugin is disabled.

Not sure what to do about it, but I really really want to get this working, I want to put the slider in just above the navbar (thats the reason I don't want it as a widget or anything else)

    node.publishdate < '. vb::$db->sql_prepare($time) .' AND
        category.categoryid IN ( 9 )
        GROUP BY node.nodeid

It stops working entirely and shows only a blank slate.

please try

    node.publishdate < '. vb::$db->sql_prepare($time) .' AND
        category.categoryid = 9
        GROUP BY node.nodeid

@Coolbluelogo
I need more debug, please follow the faq

@intruder
untested:
find

    
$output_bits = '
    <link rel="stylesheet" href="' .$slider_img_filepath. 'nivo-slider.css" type="text/css" media="screen" />
    <link rel="stylesheet" href="' .$slider_img_filepath. 'nivo-slider_uf_theme.css" type="text/css" media="screen" />
    <div style="height:' . $maxheight . 'px;">
    <div id="wrapper">

replace with:

$newheight = $maxheight + 42;
$output_bits = '
    <link rel="stylesheet" href="' .$slider_img_filepath. 'nivo-slider.css" type="text/css" media="screen" />
    <link rel="stylesheet" href="' .$slider_img_filepath. 'nivo-slider_uf_theme.css" type="text/css" media="screen" />
    <div style="height:' . $newheight . 'px;">
    <div id="wrapper">

and in the css file which you uploaded to your server find this part:

.nivo-caption {
    background: none repeat scroll 0 0 #0D2132;
    bottom: 0px;
    color: #FFFFFF;
    left: 0;
    opacity: 0.4;
    position: absolute;
    width: 100%;
    z-index: 8;
}

and change the bottom value to -42px

@Loversama
I need more information on the database error so i can help.

PHP Code:

Then the website will only some times load, half the time it will get:

Database error
The database has encountered a problem.

And the other time I get:

#articles - featured and databasepull int(7) int(7)

I also get a error in the PHP which does not display onscreen but in the logs which is:

[01-Dec-2011 02:04:44] PHP Warning: Unexpected character in input: '\' (ASCII=92) state=1 in /home1/fadertwi/public_html/includes/class_bootstrap.php(555) : eval()'d code on line 505

I have also tried the method of changing the article type as you suggested.

$article_type = vb_Types::instance()->getContentTypeID("vBCms_Article");

to

$article_type = 24;

which is the article type in the DB however that causes the process_templates_complete to not allow any other hooks, or it crashes or something..


So yea pretty stuck, but it'd be amazing if I could fix this, I am re-modling my website at the moment and I really need the slider in my header!

my website is www.SinfulShadows.com however I will have to disable the plugin as my members will not be able to access my site freely while its crashing.

Is it possible to have this on forumhome if we do not have cms? And possible instructions if so?

I tried the static code with forumhome instructions from the FAQ but could not get it working.

@Loversama
I thought that '\' Error was solved some pages ago?

the "Error occurred: picture is not readable." comes from fopen or allow_url open not beeing ON in the server configuration (i guess)

the DB-Error. I don't know, without an error message what that database error is i'm lost here.

@Booyakan
Without CMS you can only use the static version and that should be possible on forumhome either via plugin and templatehook. Or editing the template itself, or using the notice system - depending on where you want the static version to appear.

Hi @,

After I moved to another host I receive the following warrning and the images are not pulled:

PHP Code:

Warning: array_multisort() [function.array-multisort]: Argument #1 is expected to be an array or a sort flag in [path]/packages/vbcms/widget/execphp.php(191) : eval()'d code on line 110 


I would appriciate any help.

Thanks!

Problem solved: problem with the templates during migration.

The slider seems to be working for me which is great but it continues to target articles that do not have images. I have the widget code set to false; for showing sections without image, yet it continues to do so. Any one have an idea?
