CMultiFileUpload

Package system.web.widgets
Inheritance class CMultiFileUpload » CInputWidget » CWidget » CBaseController » CComponent
Since 1.0
Source Code framework/web/widgets/CMultiFileUpload.php
CMultiFileUpload generates a file input that can allow uploading multiple files at a time.

This is based on the jQuery Multi File Upload plugin. The uploaded file information can be accessed via $_FILES[widget-name], which gives an array of the uploaded files. Note, you have to set the enclosing form's 'enctype' attribute to be 'multipart/form-data'.

Example:
<?php
  $this->widget('CMultiFileUpload', array(
     'model'=>$model,
     'attribute'=>'files',
     'accept'=>'jpg|gif',
     'options'=>array(
        'onFileSelect'=>'function(e, v, m){ alert("onFileSelect - "+v) }',
        'afterFileSelect'=>'function(e, v, m){ alert("afterFileSelect - "+v) }',
        'onFileAppend'=>'function(e, v, m){ alert("onFileAppend - "+v) }',
        'afterFileAppend'=>'function(e, v, m){ alert("afterFileAppend - "+v) }',
        'onFileRemove'=>'function(e, v, m){ alert("onFileRemove - "+v) }',
        'afterFileRemove'=>'function(e, v, m){ alert("afterFileRemove - "+v) }',
     ),
  ));
?>
