United-Forum Nivo Slider Widget · **Released**: 07-17-2011

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:

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;


//Debug Messages
if($debug_modus)

	echo "<span style='color:red;'>DEBUG MODE is ON! </span><br />";

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:
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 = 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:
Code:
.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:

So, my slider stopped working. For various reasons it took a while for me to discover this sad fact. After going through all of the troubleshooting steps I was about ready to remove this dang slider mod and try something else. As a last resort, I checked my php.ini file. Right away this jumped out at me: it was set to version 5.2.

Due to some other troubleshooting, my webhost changed my PHP version back to 5.2 (without telling me). I bumped that baby back up to version 5.3 and the slider is working great! I don't claim this will work for everyone, but if you're having troubles, check it out.

Yeah this work on 4.2. I have it going smoothly.

Jamie G · #**474** 09-01-2012, 11:03 PM

I cannot get this working on 4.2.0. I get the slider, the animation and the full bck image and the article text. However, I cannot get the images to display.

Additionally, the images link incorrectly. My site is stored in a folder, not root.

So, my installation is in root/V2. Article links point to domain.com/v2/content.php - but the slider points to domain.com/content.php - does this plugin not work unless the vB install is in the root?

Hopefully someone can help ASAP.

try doing:

$slider_img_filepath = '/clientscript/slider/';

So, my installation is in root/V2. Article links point to domain.com/v2/content.php - but the slider points to domain.com/content.php - does this plugin not work unless the vB install is in the root?

Hopefully someone can help ASAP.

I have the same problem but a bit different in the img_dir I have

$slider_img_filepath = '/foros/slideshow/';

this works as it executes the jscript and displays the articles with the default image however the article images/attachments do not display when I look at the debug code the absolute path that it shows is incorrect as it shows /sitehomedir/foros/foros/slideshow/ and of course it doesn't find the images there.

if I change the img_filepath to remove the duplicate foros entry like this:

$slider_img_filepath = '/slideshow/';

then it doesn't find the rest of the script and only it looks worst.

this sounds like an easy fix but I just don't know where to specify the full server path even if I hardcode it in.

I didnt go through all 32 pages, but can the image be displayed as its original size to prevent distortion?
