Question

There is a field for price in my form that will be saved in a decimal format into db.

Now if a user types commas ‘,‘ not points ‘.‘, how can I quietly replace it so that it will be saved correctly? eg instead of 12,34, there will be saved 12.34, not 12.00

Answer 1

It would probably be easiest if you used a CFilterValidator to convert the input from a string to a float value automatically when validation happens; the rest should take care of itself.

So your model would have

public function rules() {
    return array(
        array('price', 'filter', 'filter' => 'convertToFloat'),
    );
}

and the filtering function would be something like

function convertToFloat($value) {
    return floatval(trim(str_replace(',', '.', $value)));
}

You can also specify the filtering function as any valid callable, for example make it a model method and specify it as

'filter' => array($this, 'convertToFloat')
