|
* run ?flush=all in CMS to force the templates to regenerate
|
|
|
|
## Usage

|
|
|
### Usage 1
|
|
Simplest usage, add the component to your GridField as below. The component will find the first Image has_one relation on the managed Model and it's editable db fields
|
|
|
|
$config->addComponent(new GridFieldBulkImageUpload());
|
|
|
|
### Usage 2

|
You can specify which Image field to use and which fields are editable from the managed Model
|
|
$imageField (string): The name of the image field to use (should have 'ID' at the end: If your relation is set has 'MyImage' => 'Image', the parameter should be 'MyImageID')
|
|
$editableFields (array): list of db fields name as string that will be editable like: array('myTextField', 'myVarcharField', 'myEnumField')
|
|
|
|
$config->addComponent(new GridFieldBulkImageUpload( $imageField, $editableFields ));
|
|
|
|
### Sample Files
|
|
|
|
#### Page Model
|
|
|
|
class Page extends SiteTree {
|
|
|
|
public static $db = array(
|
|
);
|
|
|
|
public static $has_many = array(
|
|
'Visuals' => 'Visual'
|
|
);
|
|
|
|
public function getCMSFields() {
|
|
$fields = parent::getCMSFields();
|
|
|
|
$config = GridFieldConfig_RelationEditor::create();
|
|
$config->addComponent(new GridFieldBulkImageUpload());
|
|
$f = new GridField('Visuals', 'Case Study Visuals', $this->Visuals(), $config);
|
|
$fields->addFieldToTab('Root.Visuals', $f);
|
|
|
|
return $fields;
|
|
}
|
|
|
|
}
|
|
|
|
#### Visual Model
|
|
('Image', 'Type', 'Title' and 'Embed' Fields will be picked up automatically by the component)
|
|
|
|
class Visual extends DataObject
|
|
{
|
|
public static $db = array(
|
|
'Type' => "Enum('Image,Embed','Image')",
|
|
'Title' => 'Text',
|
|
'Embed' => 'HTMLText'
|
|
);
|
|
|
|
public static $has_one = array(
|
|
'Page' => 'Page',
|
|
'Image' => 'Image'
|
|
);
|
|
|
|
public function getCMSFields() {
|
|
$fields = new FieldList();
|
|
|
|
$fields->push( new DropdownField(
|
|
'Type',
|
|
'Type of visual',
|
|
singleton('Visual')->dbObject('Type')->enumValues()
|
|
));
|
|
|
|
$fields->push( new TextField('Title', 'Title and Caption for images (useful for SEO)') );
|
|
$fields->push( new TextareaField('Embed', 'HTML Embed code') );
|
|
|
|
$f = new UploadField('Image', 'Image file');
|
|
$fields->push($f);
|
|
|
|
return $fields;
|
|
}
|
|
}
|
|
|
|
## Notes
|
|
* The HTML form fields for each editable fields are taken from the Model's getCMSFields() method
|
|
* Only (HTML)Text/Varchar and Enum fields are picked up by the automatic config for now
|
|
|
|
## @TODO
|
|
* Add option to specify upload folder
|
|
* Add individual actions for each upload (update + cancel)
|
|
* Styles: fade progress bar back to blue once updated
|
|
* Styles: add .loading class to buttons when saving/canceling
|
|
* Handle and display errors better for: creation, update, cancel
|
|
* Make it work not only for images -> might need to rename this component then? |
