symfony - clean variables before sending to template

Question

Hi!

On the project I am currently working, I had created an action that generates a csv file.

Here is some of my current template codem, which generated the csv file on-the-fly:

<?php header('Content-Disposition: attachment; filename="file_'.date("Y-m-d_H-i",time()) .'.csv"'); ?>
Branch:;<?php echo $branch; ?>;

The variable $branch, needs some formatting to be displayed on the csv file. For now, all the cleaning/formatting work is being done on the action itself but I do know it is not the most adequate place.

Should I create a private auxiliary function on the file that contains the action or it is recommended a more suitable place?

Note that I would like to avoid to perform the cleaning/formatting work on the template because some is quite extensive.

Thanks in advance for the help, Best regards!

Answer 1

You can do this one of several ways.

But the most "symfony" way would be to create a validator and implement your formatting in the doClean() method.

Answer 2

Why not just create a class in your /lib/model directory. Symfony will automatically load it, and you can start using it in your code.

Put your cleanup functions inside that class and call it from your template.

e.g /lib/model/doctrine/cleanup.class.php

class cleanup
{
    public function cleanitup($txt) { // docleanup }
{

//$cleaner = new cleanup();
//$cleaner->cleaneitup($foo);

Answer 3

You can also create a helper (helpers are designed for this kind of operation).

1. create a file stuffHelper.php in a lib/helper directory
2. add your function clean_stuff() inside
3. load it with use_helper('stuff') in your template
4. echo clean_stuff($myStuff) in the template

But not in the model, it's a view method !
