Cant access $myVariable!

H, still trying to solve this.

In my page class, I have a function that take all images from a selected folder, and returns list of images.
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -return ($folder = $this->PortfolioFolder()) ? DataObject::get("Image", "ParentID = '{$folder->ID}'") : false;
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
In my template, i have this
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -<% control ImagesIDE %>
<img src="$URL" alt="$Caption" />
<% end_control %>which i wrapped within Fotorama div. Works fine. Note the red bit.
Problem is that i need to acces a caption for that image and my function isnt returning other thing that the $URL variable.
Fotorama uses the alt="..." for description.

Solution i thought of....

<img src="$URL" alt="$Title" />
and it returned this
<img src="...." alt="image_aaa.jpg" />
So i said, where does that comes from? Quickly, i thought about the FILES pabel into the CMS. Yes, there is a title there.

QUESTION
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -Is there a way i could add another textfield into that part of the CMS? Like that:
So i could use
<img src="$URL" alt="$Caption" />
Thanks!

Why don't you just use the title field as your alt tag? Is there a specific reason you can't?

Well, as i said:
<img src="$URL" alt="$Title" />
returns this
<img src="...." alt="image_aaa.jpg" />
The NAME of the file
= = =
And when i try to change de Title parameter in the FILES panel (as shown below into the CMS), the CMS freezes...
= = =
Is is a bug? I mean could it be that simple as changing the title of my image and then <img src="..." alt="$Title" />

Well, well, it seems that i CAN now edit images and attribute a description into title and access it via alt="$Title"
while i couldnt do it previously.
One worthy note is that if i use
UPLOAD IMAGES BUTTON => it fails to edit
DRAG & DROP => i can edit details....
- - -
Anyhow, its not that relevent to my problem as i need to be able to add style to that description, like wrapping a word or two between <strong> tags.

So, can one add customs textfields into the CMS IMG ADMIN panel?
Thanks!

It appears you can.. i didn't test as an extension but it should work.
You want to first extend the File class through a DataExtension, and add your new description text field
class FileExtension extends DataExtension {
public static $db=array(
'Description'=>'Text'
);
}then you want to add your new field through the updateCMSFields() function like so in your FileExtension class
public function updateCMSFields(FieldList $fields){
$fields->addFieldToTab('Root.Main', new TextField('Description'));
}and then in your _config.php add
Object::add_extension('File', 'FileExtension');
and then do a dev/build/?flush=all. Let me know if that works or not.

Hi, first thanks for helping. It is not working though. the CMS freezes. Let me recap.
/******** mysite/code/FileExtension.php
class FileExtension extends DataExtension {
public static $db=array(
'Description'=>'Text'
);public function updateCMSFields(FieldList $fields){
$fields->addFieldToTab('Root.Main', new TextField('Description'));
}
}/********* mysite/_config.php
Object::add_extension('File', 'FileExtension');
After a dev/build, the CMS shows nothing. I can log but if i click on FILES, the right part of the CMS goes blank.
I am using SS3, if that changes something.
Thanks!

Did you also do a ?flush=all ?
Check your console for any errors and let me know what it says. If you can't get that I should be able to try this myself again later today.

Hi, no error that i know of. Chrome Error Console shows nothing.
Can you confirm that i have to:
1 - copy your code into FileExtension.php WITH NO TYPO.....
class FileExtension extends DataExtension {
public static $db=array(
'Description'=>'Text'
);public function updateCMSFields(FieldList $fields){
$fields->addFieldToTab('Root.Main', new TextField('Description'));
}
}Question, no controller needed????
2 - place FileExtension.php into mysite/code
3 - copy your code (below into mysite/_config.php
Object::add_extension('File', 'FileExtension');
4 - Run a dev/build?flush=all
Thanks!
