Hello,

I've created a public download section by extending dataObject.
I want to add some extra functionality, but couldn't find it in the docs/forums so ill post it here.

Code:

<?php

class publicDownloadPage extends Page {

   static $has_many = array (
      'Downloads' => 'Download'
   );
   
   public function getCMSFields() {
$fields = parent::getCMSFields();
$manager = new FileDataObjectManager(
$this,
'Downloads', // relation name
'Download', // class name of the DataObject
'File', // name of the file relation in the DataObject
array(
         'ID' => 'ID',
          'Title' => 'Title',
          'Comment' => 'Comment'
       ), // headings
'getCMSFields_forPopup' // name of the function for the popup fields

);
$fields->addFieldToTab('Root.Content.Files', $manager);
return $fields;
}

}

class publicDownloadPage_Controller extends Page_Controller {

}

class Download extends DataObject {

   static $db = array (
      'Title' => 'Text',
      'Comment' => 'HTMLText'
   );
   static $has_one = array (
      'File' => 'File',
      'publicDownloadPage' => 'publicDownloadPage'
   );

   public function getCMSFields_forPopup() {
      $fields = new FieldSet();
      $fields->push(new TextField('Title'));
      $fields->push(new SimpleTinyMCEField('Comment'));
      $fields->push(new FileUploadField('File','Upload a file'));
      return $fields;
   }

}

Template code

<% control Downloads %>

                        <% control File %>
                           <a href="$URL" target="_blank"><img src="$URL" width="130" /></a>
                        <% end_control %>
                     </div>
                     <div id="Downloads_text">
                        <table width="100%">
                           <tr height="12px">
                              <td><h4>FILENAME</h4></td>
                              <td><h4>SIZE</h4></td>
                           </tr>
                           <tr height="32px">
                              <td><p>$Title</p></td>
                              <td><p>$Size</p></td>
                           </tr>
                           <tr height="12px">
                              <td><h4>COMMENT</h4></td>
                              <td><h4>TYPE</h4></td>
                           </tr>
                           <tr>
                              <td><p>$Comment</p></td>
                              <td><p>$Type</p></td>
                           </tr>
                        </table>

            <% end_control %>
   

Question 1:
I would like to be able to recognise the file type/extentions

How would I do this?

Question 2:
When uploading a file you need to fill in the 'Title' and 'Comment' field. I would like some default value's at startup.
The 'Title' field must be by default the 'filename'.

Question 3:
How do i get the filesize displayed in the template?

Question 4:
I want to display a thumbnail, normally I just do $imageName.setWidth(130)
But how do i do this when you use <% control File %> ?

Solved it now in an ugly way:

<% control File %>
<a href="$URL" target="_blank"><img src="$URL" width="130" /></a>
<% end_control %>

Any help would be great!
Thx

1) $File.Extension

2)

public function onBeforeWrite() {
parent::onBeforeWrite();
if(!$this->Title && $this->FileID) {
$this->Title = $this->File()->Filename;
}
if(!$this->Comment) {
$this->Comment = "Some comment";
}
}

3) $File.Size

4) <% control YourImageObject %>$SetWidth(130), $CroppedImage(50,50), etc..<% end_control %>

Dude! thx it was quite easy.

But the setwidth isn't working.

                        <% control File %>
                           <a href="$URL" target="_blank">
                              <% control YourImageObject %>
                                 $SetWidth(130)
                              <% end_control %>
                           </a>
                        <% end_control %>

Any ID?

(oh btw the thumbnail isnt showing in the browser ;) )

Oh one more question:

When using your script with 'Filename' i get the path+file name.

For instance:

assets/Public_Downloads/Backgrounds/filename.jpg

and i would like to only have 'filename.jpg'

Do you really have a relation called "YourImageObject" ?? I hope you didn't take that literally.

Whatever the name of your image relationship is. If you have:

$has_one = array (
'SomeImage' => 'Image'
);

then <% control SomeImage %>
