In symfony 1.4, how can I fetch data from a text file in the 'new template' page?

[speceiste]

I want to read a text file in the 'new template' of a module, so I can retrieve a number in that file, and give it as a field at the moment of saving that register. As an example, in the form I have this fields:\[code\]name:description:number:\[/code\]The number field is in the text file, and I want to retrieve it before I press the "Save" button.How could I do that?Thanks for your consideration.
