Media field URL and preview

[szepeviktor]

Should I use field_{instantiated class name}_{section id}_{field ID} to put the media link into the input's value?

Is there a way to display preview for media field type?

[szepeviktor]

Wait!
For image type:

The supported attributes are, 'title', 'alt', 'width', 'height', 'caption', 'id', 'align', and 'link'.

For media type only

The supported attributes are, 'id', 'caption', and 'description'.

Would it be possible to support all data that can be set in the "Insert Media" dialog?
'title', 'alt', 'width', 'height', 'caption', 'id', 'align', 'link'
and 'size' also, as it is available.

There is no preview option for the media field type at the moment.

Not sure. I'll check.

When the media uploader dialog is closed, an attachment object is passed to the JavaScript method (

admin-page-framework/development/factory/_common/form/field_type/AdminPageFramework_FieldType_media.php

Line 259 in e23d481

_oMediaUploader.state().get( 'selection' ).each( function( oAttachment, iIndex ) {

) and its attributes property holds the following members (the values are an example).

alt: "Alt value"
author: "1"
authorName: "admin"
caption: "This is a caption."

I don't see size and align in that property object so it is hard to set them to the input fields of the form created by the framework.

If you know a way to retrieve them, let me know.

Coudl it be sizes: Object?

[michaeluno]

The sizes property looks like this and no information for which one the user selected.

full: Object
    height: 768
    orientation: "landscape"

You can check the object by inserting console.log( oAttachment ); after the highlighted line posted in the previous reply. You'll find the attributes property.

I've roughly searched the web and could not find a proper way to retrieve all the selected options in the media uploader form including the ones you requested such as size and alignment. It's not impossible to code to retrieve those but if there is already an establish method to retrieve them, it should be used. Let me know if you know it.
