thanks, subforms seem to be way to go.
Re the valid php variable names, I was thinking of extending Zend_Form to work
around this specifically removing the preg_replace on line 823 and wrinting a
processor for looking for the first array form as an integer and thus know that
it is an update (if empty, know that it's an insert). But I'm a little nervous
changing overriding filterName like this. Is there anything that could cause
problems?
817 public function filterName($value, $allowBrackets = false)
818 {
819 $charset = '^a-zA-Z0-9_\x7f-\xff';
820 if ($allowBrackets) {
821 $charset .= '\[\]';
822 }
823 //return preg_replace('/[' . $charset . ']/', '', (string) $value);
824 return (string) $value;
825 }
which would allow me to do something like this:
155 $form=new Zend_Form();
156 $form->setAction('/fadmin/app/filter/show/')->setMethod('post');
157 $form->addElement('text','group_name');
158
$points=array(array('id'=>1,'first_name'=>'Amanda','last_name'=>'Salter'),
159
array('id'=>2,'first_name'=>'Britney','last_name'=>'Goin'));
160
161 foreach($points as $row){
162 $sub=new Zend_Form_SubForm();
163 $fn=new Zend_Form_Element_Text('first_name_new');
164 $fn->setBelongsTo(69);
165 $sub->addElements(array($fn));
166 //$options=array('elementPrefixPath'=>array(12,14,16));
167 //$sub->setOptions($options);
168
169 if($sub instanceof Zend_Form){
170 echo "this is an instance of Zend_Form!<br/>";
171 }
172 $forms['users['.$row['id'].']']=$sub;
173 //$form->addSubForm($sub,'bird');
174
175 }
176 $form->addSubForms($forms);
177 $form->addElement('submit','click on me!');
178 $this->view->form=$form;
179 }
and render into:
<input type="text" name="users[1][first_name_new]" id="users-1-first_name_new"
value=""><br/>
<input type="text" name="users[2][first_name_new]" id="users-2-first_name_new"
value=""><br/>

Use sub forms. Sub forms are for exactly this sort of semantic grouping,
and by default render using array notation. Sub forms may be nested
infinitely deep.
One note, however: form element names must be valid PHP variable names
-- so numeric keys simply will not work currently.
