[fw-general] Zend_Form File element toggle between image

[Edward Haber]

Thanks in advance for any thoughts on the following:

1) Can anyone suggest the best way to implement the following in a  
form: a Zend_Form_Element_File if no image has been uploaded. But if  
an image has been uploaded, the image appears with a "delete" button.  
Would a custom form element be best or would you just hide/show the  
various elements with Javascript? Or is it already built-in!?

2) And as a second question: I can't find any way to do this. Is there  
any way to just insert a random blob or row of HTML in your form like:
<dl>
        <dt>Label</dt><dd><input type...></dd>
        <dt>Label</dt><dd><input type...></dd>
        <dt>Label</dt><dd><input type...></dd>

        <p>Hi look at me!</p>

        <dt>Label</dt><dd><input type...></dd>
        <dt>Label</dt><dd><input type...></dd>
</dl>
Is there any way to insert the line "Hi look at me!" without  
decorating the element above it or below it and without creating a  
custom class?

3) Is there a problem with the current version of the  
Zend_Form_Element_File? The element doesn't appear to print with the  
row decorator.

<?php

class forms_AdminArticleForm extends Zend_Dojo_Form
{
        public function __construct($options = null)
        {
                parent::__construct($options);
                $this->setName('article_form')
                        ->setAction(URL.'/admin/article/save')
                        ->setMethod('post')
                        ->setAttrib('enctype', 'multipart/form-data')
                        ->setAttrib('id', 'article-form');
                
                $title = new Zend_Form_Element_Text('title');
                $title->setLabel('Title')
                        ->setRequired(true)
                        ->addValidator('NotEmpty')
                        ->setAttribs(array('size'=>'40'))
                        ->addValidator('StringLength', false, array(1, 128));
                
                $author = new Zend_Form_Element_Text('author');
                $author->setLabel('Author')
                        ->setRequired(true)
                        ->setAttribs(array('size'=>'40'))
                        ->addValidator('NotEmpty')
                        ->addValidator('StringLength', false, array(1, 64));
                        
                $image = new Zend_Form_Element_File('image_name');
                $image->setLabel('Upload an image:')
                        ->setDestination(AP . '/application/tmp/upload-staging')
                        ->addValidator('Size', '500kb');

                $submit = new Zend_Form_Element_Submit('action');
                $submit->setLabel('Save');
                                
                $this->addElements(array(
                        $title, $author, $image, $submit
                ));
        }
}

This class generates the following HTML code:

<form id="article-form" action="/admin/article/edit" method="post"  
enctype="multipart/form-data">
<dl class="zend_form">

<dt><label for="title" class="required">Title</label></dt>
<dd><input type="text" name="title" id="title" value="Here ya go"  
size="40"></dd>

<dt><label for="author" class="required">Author</label></dt>
<dd><input type="text" name="author" id="author" value="dudeness"  
size="40"></dd>

<input type="file" name="image_name" id="image_name" helper="formFile">

<dt>&nbsp;</dt>
<dd><input type="submit" name="action" id="action" value="Save"></dd>

<dt>&nbsp;</dt>
<dd><input type="hidden" name="article_id" value="4" id="article_id"></ 
dd>
</dl>
</form>
