I just thought I would what I wrote in the other question here so it's easier to follow.
I have just notice a slight problem in how I have set up my image feilds. I am building a portfolio site and I wanted to have images that would be added to a featured section on the site which I did like this:
PortfolioPage.php
<?php
/**
* Defines the ArticlePage page type
*/
class PortfolioPage extends Page {
static $db = array(
'Date' => 'Date',
'Author' => 'Text',
'Client' => 'Text',
'Task' => 'Text',
'Role' => 'Text'
);
static $has_one = array(
'FeatureWork' => 'PortfolioPage_FeatureWork',
'RecentThumb' => 'PortfolioPage_RecentThumb',
'PortImage' => 'Image'
);
function getCMSFields() {
$fields = parent::getCMSFields();
$fields->addFieldToTab('Root.Content.Main', new CalendarDateField('Date'), 'Content');
$fields->addFieldToTab('Root.Content.Main', new TextField('Author'), 'Content');
$fields->addFieldToTab('Root.Content.Main', new TextField('Client'), 'Content');
$fields->addFieldToTab('Root.Content.Main', new TextField('Task'), 'Content');
$fields->addFieldToTab('Root.Content.Main', new TextField('Role'), 'Content');
$fields->addFieldToTab('Root.Content.Images', new ImageField('FeatureWork'));
$fields->addFieldToTab('Root.Content.Images', new ImageField('RecentThumb'));
$fields->addFieldToTab('Root.Content.Images', new ImageField('PortImage'));
return $fields;
}
static $icon = "themes/tutorial/images/treeicons/news";
static $defaults = array(
'ProvideComments' => true
);
}
class PortfolioPage_Controller extends Page_Controller {
}
class PortfolioPage_FeatureWork extends Image {
function generatePortfolioFeature($gd) {
$gd->setQuality(100);
return $gd;
}
}
class PortfolioPage_RecentThumb extends Image {
function generatePortfolioRecentThumbnail($gd) {
$gd->setQuality(100);
return $gd;
}
}
?>
HomePage.php
<?php
/**
* Defines the HomePage page type
*/
class HomePage extends Page {
static $db = array(
);
static $has_one = array(
);
static $allowed_children = array('PortfolioPage');
static $icon = "themes/tutorial/images/treeicons/home";
}
class HomePage_Controller extends Page_Controller {
/*Function calls Articles on to the homepage showing only the first Paragraph*/
function LatestNews($num=5) {
$news = DataObject::get_one("PortfolioHolder");
return ($news) ? DataObject::get("PortfolioPage", "ParentID = $news->ID", "Date DESC", "", $num) : false;
}
function RecentPortfolioUpdate($num=4) {
$news = DataObject::get_one("PortfolioHolder");
return ($news) ? DataObject::get("PortfolioPage", "ParentID = $news->ID", "Date DESC", "", $num) : false;
}
}
?>
HomePage.ss
<div id="feature">
<% control LatestNews %>
<a href="$Link" title="Read more on "{$Title}""><img src="$FeatureWork.PortfolioFeature.URL" id="feature_image"></a>
<% end_control %>
</div>
All this does as it is meant to and shows the images in the FeatureWork ImageFeild where they should be in the jQuery as you can see HERE. However my problem is that because it is a featured section I only want it to show pages where I have actually uploaded a image in the FeatureWork ImageFeild. Oviously every time I create a new PortfolioPage I will have that image field their but I wont always be adding an image to it, and at the moment when I dont I get an empty block in the image slider because it wants to add an image.
