This extension offers a non-intrusive Yii extension that allows you to use the JCrop jQuery plugin in your Yii project. Unlike other extensions, yii-jcrop does NOT auto-insert the form fields and buttons for you, which in many cases might not be what you want anyway. This extension focuses on the minimum required to get you up and running, letting you do your own bells and whistles if you want to. This project is not a fork of the JCrop Extension

Optionally, this extension supports a preview of the cropped image which will be dynamically updated as you move the selection rectangle.




Yii 1.1 or above, GD or Imagick support for your serverside cropping code


Copy/extract the yii-jcrop folder into your protected/extensions/ directory. This is an example view that uses the widget:

<?php echo CHtml::errorSummary($form); ?> 
    <?=CHtml::beginForm(null, 'POST')?>
    <? //$form in this example is of type AvatarForm, containing variables for the crop area's x, y, width and height, hence the corresponding widget form element parameters ?>
    <?=CHtml::activeHiddenField($form, 'cropID');?>
    <?=CHtml::activeHiddenField($form, 'cropX', array('value' => '0'));?>
    <?=CHtml::activeHiddenField($form, 'cropY', array('value' => '0'));?>
    <?=CHtml::activeHiddenField($form, 'cropW', array('value' => '100'));?>
    <?=CHtml::activeHiddenField($form, 'cropH', array('value' => '100'));?>
    <?$previewWidth = 100; $previewHeight = 100;?>
		'previewId'=>'avatar-preview', //optional preview image ID, see preview div below
			'setSelect'=>array(0, 0, 100, 100),

    <!-- Begin optional preview box -->
    <div style="position:relative; overflow:hidden; width:<?=$previewWidth?>px; height:<?=$previewHeight?>px; margin-top: 10px; margin-bottom: 10px;">
	<img id="avatar-preview" src="<?=$imageUrl?>" style="width: 0px; height: 0px; margin-left: 0px; margin-top: 0px;">
    <!-- End optional preview box -->

    <?=CHtml::submitButton('Crop Avatar'); ?>

You are free to use any jCrop parameter in the jCropOptions array. This plugin works with model-based forms as well as plain forms. If you specify javascript callback function names in a jCrop-parameter, don't forget to start them with "js:"

If you don't want a preview image, just leave out the preview parameters and the associated DIV.
