Upload Progress
In This Article
FormFileSessionProgress
The FormFileSessionProgress
view helper can be used to render a <input
type="hidden" ...>
which can be used by the PHP 5.4+ File Upload Session
Progress feature.Unlike other zend-form view helpers, the
FormFileSessionProgress
helper does not accept an Element
as a parameter.
An id
attribute with a value of "progress_key"
will automatically be added.
Render early
The view helper must be rendered before the file input in the form, or upload progress will not work correctly.
Best used with the Zend\ProgressBar\Upload\SessionProgress handler.
See the Session Upload Progress chapter in the PHP documentation for more information.
Basic usage
// Within your view...
echo $this->formFileSessionProgress();
// Result: <input type="hidden" id="progress_key" name="PHP_SESSION_UPLOAD_PROGRESS" value="12345abcde">
