Hi Folks,

maybe these problem is solved somewhere, but I doesn’t found the answer by searching this forum.

You know that in Purity II the header images rotate by a random generator. Now I won’t this. I’ve 2 categories on my homepage and I want Image1 by clicking on Menulink1 and Image2 by clicking on Menulink2.

Is this possible?

Thanks
DamonWilder

Hi,
What’s about header image as you mentioned? Did you mean it’s menu image?

Hi,

I mean following images: […]/templates/ja_purity_ii/images/header/header[1-3].jpg
This 3 images should not change randomly, but by the categories. For Example: Klick on tab#1 -> image1; Klick on tab#2 -> image2, and so on.

Many thanx for your answers.
Would be nice, if this could work.

Yes, mate!

Presently, header images are displayed in the random way. You can try the following to complete your idea

1) open the templates/ja_purity_ii/libs/ja.templates.helper.php and find the following code:
[PHP]
function getRandomImage ($img_folder) {
if (!is_dir ($img_folder)) return ”;
$imglist=array();

mt_srand((double)microtime()*1000);

//use the directory class
$imgs = dir($img_folder);

//read all files from the directory, checks if are images and ads them to a list (see below how to display flash banners)
while ($file = $imgs->read()) {
if (eregi(“gif”, $file) || eregi(“jpg”, $file) || eregi(“png”, $file))
$imglist[] = $file;
}
closedir($imgs->handle);

if(!count($imglist)) return ”;

//generate a random number between 0 and the number of images
$random = mt_rand(0, count($imglist)-1);
$image = $imglist[$random];

return $image;
}
[/PHP]replace:

[PHP]
function getRandomImage ($img_folder) {
if (!is_dir ($img_folder)) return ”;
$imglist=array();

mt_srand((double)microtime()*1000);

//use the directory class
$imgs = dir($img_folder);
$itemID = (int)JRequest::getVar(‘Itemid’,0);
//read all files from the directory, checks if are images and ads them to a list (see below how to display flash banners)
while ($file = $imgs->read()) {
if (eregi(“gif”, $file) || eregi(“jpg”, $file) || eregi(“png”, $file))
$imglist[] = $file;
if( $file == ‘header-‘.$itemID.’.jpg’ ){
closedir($imgs->handle);
return $file;
}
}
closedir($imgs->handle);

if(!count($imglist)) return ”;

//generate a random number between 0 and the number of images
$random = mt_rand(0, count($imglist)-1);
$image = $imglist[$random];

return $image;
}

[/PHP]when done,

rename your images in this format:

header-+ValueOf ItemId+”.jpg”

Since this thread is already 8 months old, the posted idea doesnt work any more for the newest version.

The solution seems to be simple by replacing the “rand(1,3)”-php command in head.php, but i don’t know how to insert the ID of the current category instead.

Could someone tell me, which php-variable contains the category-ID ?

/templates/ja_purity_ii/blocks/head.php

#ja-header .main {
background-image: url(<?php echo T3Path::getUrl('/images/header/header'. rand(1,3).'.jpg'); ?>);
}


Thanks in advance 🙂
