Zend_Form输入数组

Question

Using Zend_Form, how would I create form elements like this:

<input type="file" name="file[]" value="" />
<input type="file" name="file[]" value="" />

If i don't know how many files user want to upload. Now the settings for the input type="file" look

form.elements.file.type = "File"
form.elements.file.options.required = true
form.elements.file.options.label = "File"
form.elements.file.options.validators.extension.validator = "Extension"
form.elements.file.options.validators.extension.options.extension = "gif,jpg,jpeg,png,swf"

Answer 1

Please try with this

    $image = new Zend_Form_Element_File("image");
    $image->setAttrib('multiple', true)
           ->setIsArray(true)
           ->addValidator('Extension', false, 'gif,jpg,jpeg,png,swf');
