Well just to conclude this, I saw an example on one of the symfony
docs about overwriting the formatRow method.
Firstly, my big thanks to you Sid as I would not have gotten this far
without your help .... the community again has come to the rescue.
Now for anyone that may find this useful in future here is how it
looks in the end:
My form consists of some dynamic form fields created based on values
sent in an array when the form is constructed:
public function __construct($extra_inputs = array())
{
$this->extra_inputs = $extra_inputs;
parent::__construct();
}
In addition I had to create my own custom widget which is essentially
just an ajax link to an action that forwards the value of one input
box to the action, adds that value to a session array, sends the
session array to the form using the $extra_inputs parameter above and
redisplays the form in the div with the new input box for that value
added.
So, my difficulty was that each new extra_input needed to use that
ajax link widget again alongside it but would forward to a Remove
action to remove that input from the session variable and hence from
the form. What I needed was that each new dynamic extra_input and its
associated Remove ajax link widget to be displayed one per line.
My decorator class hence looks like such and I know the names can
cause some giggles but hey :P :
class mailAnalByRecip extends sfWidgetFormSchemaFormatter
{
protected
$rowFormat = "\n%error%\n<span class=\"formRow\">\n<span
class=\"formLabel\">%label%</span>\n<span
class=\"formField\">%field%\n%help%</span></span>\n%hidden_fields%",
$helpFormat = '<span class="fieldHelp">%help%</span>',
$errorRowFormat = "<span>\n%errors%<br /></span>\n",
$errorListFormatInARow = "<ul>%errors%</ul>\n",
$errorRowFormatInARow = "<li class=\"error\">↓ %error%
↓</li>\n",
$namedErrorRowFormatInARow = "<li class=\"error\">↓ %error%
↓</li>\n",
$decoratorFormat = "%content%";
protected $fields_to_format = array();
public function __construct(sfWidgetFormSchema $widgetSchema,
$fields_to_format)
{
$this->fields_to_format = $fields_to_format;
parent::__construct($widgetSchema);
}
public function formatRow($label, $field, $errors = array(), $help =
'', $hiddenFields = null)
{
foreach ($this->fields_to_format as $field_name)
{
if (strpos($field, $field_name) !== false &&
strpos($field,
'type="text"') !== false)
{
$field = '<span class="field_row">'.$field;
}
else if (strpos($field, $field_name) !== false &&
strpos($field,
'<a') !== false)
{
$field = $field.'</span>';
}
}
$row = parent::formatRow($label, $field, $errors, $help,
$hiddenFields);
return $row;
}
}
And in my form class at the very end of the configure() method:
$decorator = new mailAnalByRecip($this->widgetSchema, $this->extra_inputs);
$this->widgetSchema->addFormFormatter('custom', $decorator);
$this->widgetSchema->setFormFormatterName('custom');
So there we go. A form class that dynamically creates widgets based on
values in an array, as well as dynamically creating a custom ajax link
widget and keeping the input and its ajax link widget associated
visually using a custom form decorator class to add spans before and
after the two widgets.
WHEW! That was one HELLUVA learning experience LOL
