Smart Backgrounds support

[loosefast]

What file does the random image generator code go into? tpl_header.php? You would want to modify the random code to choose among a set of classnames referring to your images; include a test to call the random code for the home page and a static header classname for the rest, like this:

<?php
if ($this_is_home_page) {
  $header_class = //random generator classname call - to give names like 'random1', 'random2', 'random3', etc.
}else{
  $header_class = 'static';
} ?>
<div id="headerWrapper class="<?php echo $header_class;?>">

Then you would have a set of stylesheet rules like

.smartBG_page_whatever #headerWrapper {background: url(../images/smartbg_page_whatever.jpg);}
#indexHome #headerWrapper.random1 {background: url(../images/randombg1.jpg);}
#indexHome #headerWrapper.random2 {background: url(../images/randombg2.jpg);}
#indexHome #headerWrapper.random3 {background: url(../images/randombg3.jpg);}
#indexHome #headerWrapper.random4 {background: url(../images/randombg4.jpg);}

The #indexHome will give enough specificity and priority to enforce the random selection for the home page.

If you want to use jpegs for the backgrounds, you need to either change Smart Backgrounds code to refer to .jpg instead of .gif in all places, or include a set of dummy image files with .gif suffixes to trigger the smartbg classnames, and the real .jpg files to use in the stylesheet.
Note that since you have to write the stylesheet rules manually, you don't have to refer to the same bg files as the ones the smartbg code looked for.

Glenn,

This seems like a good solution for having random backgrounds on the home page only, but don't understand what happens on the line:

$header_class = //random generator classname call - to give names like 'random1', 'random2', 'random3', etc.

would this be written as :

$header_class = random1;
$header_class = random2;
$header_class = random3;

etc?

thanks

That is where I was suggesting the modified random generator code would go. I don't know the best way to set it up for this application, but it would end up by feeding one name into $header_class.

My feeling is that you would include or require rotate.php from tpl_header.php, and modify its last line from

header('Location: '.$folder.$files[$rand]); // Voila!

to

$header_class = $files[$rand]); // class to use for header bg this time

You would also want to remove the value of $ext from $file before saving each time as $files[] so you get a simple string for the classname.

$file = str_replace($ext, '', $file);

Does anyone know if this Mod gets interference from CEON URI Mapping?

I have tried to install this mod, and I get the same class for all of my pages. Class="smartBG".

Is there a work around this? It would be an awesome mod to have. The project I'm working on is www.walls360.com/shop.

I also have the Column Grid, Gallery2 -> Zen Cart, Google Analytics, Easy Populate, Image Handler (currently disabled), and am working on getting Zen Light Box up.

Thanks for any help in advance.

It may well interfere. One of the other SEO mods caused some problem with a basic ZC function until cPath info was enabled in it, and CEON's may also eliminate info that Smart BG needs to operate. You would have to ask Conor how to get the info to be available.

Question - I got the Smart Backgrounds to work with the images I wanted.... but my client wants to change whole categories to have not only different images, but different colors as well...

Can you make a suggestion on whether I can use Smart Backgrounds for this, or whether there is another good work-around for this?

Thanks!

In the stylesheet rules you write for the images, you can also specify background-color, and anything else that you wish. As long as you have the first image that triggers the Smart BG code, you can style any element on the page with the .smartbg_whatever class prefixed.

Yup...CEON URI mapping interferes with Smart Backgrounds in case anyone wanted to know...

Is there a workaround??

I don't know how Ceon URI Mapping functions, so can't say anything about making it and Smart Backgrounds play nice together.

Fair enough.. Do you know off-hand if are there compatibility with your add-on and Simple Seo Url Module ?
