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 />";
	echo "slider_img_filepath: $slider_img_filepath <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:
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.

at the end of the widget code and insert it into the test.php file. It should show up then.

@pmflav1
That FAQ question should help you out:

I dont understand,

this is test.php file.

$templater->register_page_templates();

$templater->register('navbar', $navbar);

$templater->register('pagetitle', $pagetitle);

print_output($templater->render());



?>

this is test template:

PHP Code:

Bottom of the article you just quoted:
https://vborg.vbsupport.ru/showthread.php?t=228112

Please see this article for help with rendering templates - [vB4] Rendering templates and registering variables - a short guide

In a nutshell:
a) insert the php code from the first post here

Code:

// ###### YOUR CUSTOM CODE GOES HERE #####
$pagetitle = 'My Page Title';

b) register the variable $output
c) update your template so it does print the variable $output

Scalemotorcars · #**265** 09-20-2011, 04:07 PM

Moff, have you or do you know how to make this work without fopen. I'm not sure how to code it for curl.

My host doesn't like fopen so I'm looking for an alternative. Thanks.

@Scalemotorcars
I haven't looked into it.
The options are:
- using fitting images as article images, which do not need to be resized (delete the resizing part then)
- resizing the images via CSS (might break the nivo slider transition effects, not sure about that one) - this also would mean deleting the resizing code
- cURL, which does involve reading through the cURL documentation or googleing for "replace fOpen via cURL"

@GamersChallenge
you can remove echo "$output"; since you are using the template system.
Then in the template you need to write {vb:raw output} somewhere, and that should be it.

I think I'm almost there. Getting this error now.

Fatal error: Class 'vb_Types' not found in /home/gamersch/public_html/test.php on line 91

this is line 91:

PHP Code:


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

Mooff · #**269** 09-22-2011, 07:11 AM

Sorry for the question, but i kinda just have to ask: Do you have the vbcms?

Anyway, if you do i'm not exactly sure in which globalclass vb_Types is definded, just look into your database, i think the table is "contenttypes" and check which contenttypeid your articles have.
On our installation it would be
$article_type = 18;
could be different on yours though.

yes I have. I also have the slider working on my home page as a widget with the same code, I'll try yo look into what you said. thanx

Thanks anyway Mooff, I ended up just going with the Content slider. The load times were dragging the homepage down horribly and my host was having an issue with Fopen.
