sfDoctrineJCroppablePlugin - 1.0.7Javascript image cropper integrated with doctrine |
|
This plugin allows you to effortlessly add image editing capabilities to your admin generator backend. You'll be able to add images to your models and be presented with the awesome Jcrop (http://deepliquid.com/content/Jcrop.html) jQuery plugin.
The plugin already has a few very useful features
To install the plugin for a symfony project, the usual process is to use the symfony command line:
php symfony plugin:install sfDoctrineJCroppablePlugin
sfDoctrineJCroppablePlugin depends on the excellent sfImageTransformPlugin, but until I can figure out how to specify that dependency in the package then you'll have to install it yourself (it's getting late!)
php symfony plugin:install sfImageTransformPlugin
If the installation of either package fails (because you're running symfony 1.3 for example) then you can manually download the tgz files from
http://plugins.symfony-project.org/get/sfImageTransformPlugin/sfImageTransformPlugin-1.2.0.tgz
http://plugins.symfony-project.org/get/sfDoctrineJCroppablePlugin/sfDoctrineJCroppablePlugin-1.0.2.tgz
and then ask symfony to install the downloaded files
php symfony plugin:install sfImageTransformPlugin-1.2.0.tgz
php symfony plugin:install sfDoctrineJCroppablePlugin-1.0.2.tgz
Enable the plugins if necessary by editing config/ProjectConfiguration.class.php:
$this->enablePlugins(array('sfDoctrinePlugin', 'sfImageTransformPlugin', 'sfDoctrineJCroppablePlugin'));
If you're using symfony 1.2 which comes with doctrine 1.0 this plugin will not be able to delete the old versions of its images when it creates new ones. This is because we've not been able to find a way of getting the old filename. Upgrading to doctrine 1.1 fixes this and is a reasonably straightforward exorcise. There is a good guide here:
http://www.brandonturner.net/blog/2009/05/doctrine11-with-symfony12/
Symfony 1.3 comes with doctrine 1.2 and so this is not an issue.
You'll first want to edit config/doctrine/schema.yml to add the behaviour to one of your models:
Person:
actAs:
JCroppable:
images: [ mugshot ]
columns:
first_name: { type: string(128), notnull: true }
last_name: { type: string(128), notnull: false }
Here we have told the plugin we want one jcroppable image field called mugshot. The plugin will take care of the creation of the relevant fields in the person table.
Now we've updated/created our schema, we can tell symfony to rebuild our database.
Caution! This step will erase any data in the database that is not included in any fixtures:
php symfony doctrine:build-all-reload
Next let's configure sfImageTransform to use the gd library and to auto-detect images' mime-types (apps/backend/config/app.yml)
all:
sfImageTransformPlugin:
default_adapter: GD
mime_type:
auto_detect: true
library: gd_mime_type
If you haven't aleady done so let's create an admin module for our person model:
php symfony doctrine:generate-admin backend Person --module=person
The plugin also depends on the jquery & jcrop libraries, so you must download them (http://deepliquid.com/content/Jcrop.html) and place the two js files (jquery.Jcrop.min.js & jquery.min.js) in web/js, and the css file (jquery.Jcrop.css) in web/css:
web/js/jquery.min.js
web/js/jquery.Jcrop.min.js
web/css/jquery.Jcrop.css
Now we need to tell our module's view to include them. We can do this specifically for our module by editing apps/backend/modules/person/config/view.yml, or for the whole application by editing apps/backend/config/view.yml:
default:
javascripts: [jquery.min.js, jquery.Jcrop.min.js]
stylesheets: [jquery.Jcrop.css]
We're almost finished now! Just two things left to do. First we have to configure the widget & validator for our jcroppable image field. Add the following calls to configure the widgets & validators to the form's configure function (lib/form/doctrine/PersonForm.class.php):
public function configure()
{
$this->getObject()->configureJCropWidgets($this);
$this->getObject()->configureJCropValidators($this);
}
And finally create the upload directory for the images to be stored in and make them writeable:
mkdir -p web/uploads/images/Person
chmod 777 web/uploads/images/Person
That's it! Now if you followed the instructions carefully then you should be able to aim your browser at the backend app's person module and add a few people and their mug shots.
To show the images in your frontend templates, simply pass a Person object, and call the getImageSrc() or the getImageTag() function, passing the desired image & size, eg
<img src="<?php echo $person->getImageSrc('mugshot', 'thumb') ?>" alt="Mug shot!" />
or
<?php echo $person->getImageTag('mugshot', 'thumb') ?>
Now the above example has used a load of default values which you'll almost definitely want to configure. Here's an example of some config you can place in your config/app.yml:
all:
sfDoctrineJCroppablePlugin:
models:
Person:
directory: people
images:
mugshot:
padding: { percent: 35, color: #ffffff }
ratio: 1.5
sizes:
thumb: { width: 450 }
main: { width: 675 }
Let's run through these options:
