[Solved] HasManyFileManager: get last column, put css class to every nth item
25 March 2009 at 10:38pm Last edited: 26 March 2009 2:38am
Hello Community,
as i found nothing about this problem in the forum that worked for me, i want to post my solution.
Maybe this will help some newbies like meI wanted do build a small Gallery with HasManyFileManager and needed something like this with floating elemts:
IMG margin IMG margin IMG margin IMG
IMG margin IMG margin IMG margin IMGSo i need to check evety nth item to put whatever in my template code.
As postet here by Sam, i can not access some iterator function placed in Page_Controller or Page class from within my <% control ... %>-functionThis is how i finally did it:
I can now define the name/group and number of columns in my template (it's more flexible than defining this in my php file - maybe i will have multiple HasManyFileManager on a page or want different numbers or columns on different pages) and i don't lose the sorting of the images that i've done in HasManyFileManager:GalleryPage.php
class GaleriePage extends Page {
......
function getCMSFields() {
......
$minigallery = new HasManyFileManager(
$this,
'GalleryImages', // name -> will be used for file grouping
'Images' // relation name defined in $has_many
);
$fields->addFieldToTab('Root.Content.Galerie', $minigallery);
......
}......
function AttachedFilesColumns($Group,$Cols=0) {
$Data = $this -> AttachedFiles($Group);
$output = new DataObjectSet();
$i = 0;
foreach($Data as $Data) {
$i++;
if($Cols != 0) {
if($i % $Cols == 0) {
$Data->Col = "last";
$i = 0;
} else {
$Data->Col = $i;
}
} else {
$Data->Col = $i;
}
$output->push($Data);
}
return $output;
}}
now in my template instead of "<% control AttachedFiles(GalleryImages) %>" i can use "<% control AttachedFilesColumns(GalleryImages,4) %>" where argument1 is the group name used by HasManyFileManager and argument2 is the number of columns.
Example:
<% control AttachedFilesColumns(GalleryImages,4) %>
<div class="GalerieThumb-$Col"><a>img<a></div>
<% end_control %>Output:
<div class="GalerieThumb-1"><a>img<a></div>
<div class="GalerieThumb-2"><a>img<a></div>
<div class="GalerieThumb-3"><a>img<a></div>
<div class="GalerieThumb-last"><a>img<a></div>
<div class="GalerieThumb-1"><a>img<a></div>
<div class="GalerieThumb-2"><a>img<a></div>
<div class="GalerieThumb-3"><a>img<a></div>
<div class="GalerieThumb-last"><a>img<a></div>
....now the last "column" in "each row" is accessible via css
(or i could use an if-block to check the $Col-output and place tr-tags for a table in the code)-----------------------
wihtout argument2 for number of columns
<% control AttachedFilesColumns(GalleryImages) %>
<div class="GalerieThumb-$Col"><a>img<a></div>
<% end_control %>Output:
<div class="GalerieThumb-1"><a>img<a></div>
<div class="GalerieThumb-2"><a>img<a></div>
<div class="GalerieThumb-3"><a>img<a></div>
<div class="GalerieThumb-4"><a>img<a></div>
<div class="GalerieThumb-5"><a>img<a></div>
<div class="GalerieThumb-6"><a>img<a></div>
