module Field Name Unprefixer

From the README.md:
 
Makes it possible to access prefixed field names without the prefix.
 
Usage
 
Create some prefixed fields and add it to you desired template, for example prefix_myField and otherPrefix_myOtherField.
Configure the prefixes, that should be removed in your /site/config.php, like so:

$config->FieldnameUnprefixer = array(
    'basic-page' => array('prefix_', 'otherPrefix_'),
    'home' => array('prefix_', 'otherPrefix_')
);

The first array keys are the template names.
The Prefixes also can be assigned as a string if it's just a single one:

$config->FieldnameUnprefixer = array(
    'basic-page' => 'prefix_',
    'home' => 'otherPrefix_'
);

Now you can access the fields without the prefix, like so:

echo $page->myField;
echo $page->myOtherField;

The unprefixed field names are now also accessible via selectors, but only for already fetched data, since the field is not really in the database:

// not
$pages->find('myField=something');
// but
$pages->find('template.name=basic-page')->filter('myField=something');

Use case
 
Prefixes are sometimes necessary to have fields that behave specific to the template, so you need to create a specific field and namespace it with a prefix, but don't want to access the fields differently on each template.

// eeew!
$client->client_address;
$something->something_address;

// yay!
$client->address;
$something->address;

Might be not the ProcessWire-way because data access is abstracted, but I use it, and perhaps some of you find it useful too.

Thanks for this, Owzim - I do think it's a great module to have.

Any way I can apply a prefix-check to all templates? I'm showing data in a footer, gathered from the home page, so I don't want to specify the prefix for every template I create...

Hi Mike,

not possible at the moment, but I just looked into the code, should be easy to implement, with selectors.

Instead of $templates->get("name"), I would use $templates->find("selector"), and loop through them.

But it needs to be tested as well and unfortunately I haven't got the time at the moment.

Feel free to make a PR

Hi owzim

I see. If I get some time, I'll make a PR.

Ah, right - force of habit, I guess. ;-)
