displaying a form
See Template:Vbzcart/code (inside function AdminPage_basic()) for a working example of a full-page form.
It can also be done without templates by retrieving the control and asking it to render itself:<php> $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); </php> ...(and so on), then manually plugging the rendered controls into the desired output format:<php> $out .= <<<__END__
...
| ID: | $id |
| Tag: | $ftTag |
| Status: | $ftStatus |
| Customer: | $ftCust |
| Address: | $ftAddr |
| Name: | $ftName |
