The FormFileApcProgress view helper can be used to render a <input type="hidden" ...> with a progress ID value used by the APC File Upload Progress feature. The APC PHP module is required for this view helper to work. Unlike other 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\ApcProgress handler.

See the apc.rfc1867 ini setting in the APC Configuration documentation for more information.

Basic usage

// Within your view...

echo $this->formFileApcProgress();
// Result: <input type="hidden" id="progress_key" name="APC_UPLOAD_PROGRESS" value="12345abcde">
