displaying a form
See Template:L/vc/code for a working example of a full-page form, and Template:L/vc/code for building a template.
template example
private $tpPage;
protected function PageTemplate() {
if (empty($this->tpPage)) {
$sTplt = <<<__END__
<table>
<tr><td align=right><b>ID</b>:</td><td>[[ID]]</td></tr>
<tr><td align=right><b>Status</b>:</td><td>[[Status]]</td></tr>
<tr><td align=right><b>Cart</b>:</td><td>[[Cart]]</td></tr>
</php>...<php>
<tr><td align=right><b>Ship $ quoted</b>:</td><td>[[QuoShip]]</td></tr>
<tr><td align=right><b>Final $ quoted</b>:</td><tr>[[QuoFinal]]</td></tr>
<tr><td align=center colspan=2>
<table>
[[AmtMerch]]
[[BalBtnsLine]]
[[RecalcLine]]
</table>
</td></tr>
</table>
__END__;
$this->tpPage = new fcTemplate_array('[[',']]',$sTplt);
}
return $this->tpPage;
without templates
It can also be done without templates by retrieving the control and asking it to render itself:
$oForm = $this->EditForm(); // retrieve the form object (build it if needed)
$oForm->LoadRecord(); // copy values from {memory image of record} to {form fields}
$ftTag = $oForm->ControlObject('Name')->Render($doEdit);
$ftCust = $oForm->ControlObject('ID_Cust')->Render($doEdit);
$ftAddr = $oForm->ControlObject('ID_Addr')->Render($doEdit);
$ftName = $oForm->ControlObject('ID_Name')->Render($doEdit);
...(and so on), then manually plugging the rendered controls into the desired output format:
$out .= <<<__END__
<table>
<tr><td align=right><b>ID</b>:</td><td>$id</td></tr>
<tr><td align=right><b>Tag</b>:</td><td>$ftTag</td></tr>
<tr><td align=right><b>Status</b>:</td><td>$ftStatus</td></tr>
<tr><td align=right><b>Customer</b>:</td><td>$ftCust</td></tr>
<tr><td align=right><b>Address</b>:</td><td>$ftAddr</td></tr>
<tr><td align=right><b>Name</b>:</td><td>$ftName</td></tr>
...
</table>
__END__;
...but note that calling LoadRecord() causes the Field objects to return TRUE from IsChanged() if the loaded value is non-NULL. This overrides POST data in $oForm->Save(), so presumably you'll need to build the update query manually or else clear the form fields somehow (currently not supported, but maybe it should be).
