decimalvalidator This code is some I wrote to try and enforce data constraints for DECIMAL(m,n) column format.

  1. Requirements
  2. Usage

This code is some I wrote to try and enforce data constraints for DECIMAL(m,n) column format, since Yii treats them as string. It does NOT support scientific / "E" notation format, for example:

-0.5, supported

-5e-1, NOT supported

Requirements

Only tested in Yii 1.1.14 and 1.1.15, but should work for other versions of Yii 1.x

Usage

I have DecimalValidator.php in components/validators/ folder, ensuring autoloading in config/main.php:

// autoloading model and component classes
    'import'=>array(
        /* ... */
        'application.components.validators.*',
    ),

Then to use it for a field, like so:

/**
     * @return array validation rules for model attributes.
     */
    public function rules()
    {
        // NOTE: you should only define rules for those attributes that
        // will receive user inputs.
        return array(
            // DECIMAL(7,2); 7 digits max length, 2 precision. allows sign (+ or -) by default
            array('adjust_fee', 'DecimalValidator', 'm'=>7, 'n' => 2),
            // DECIMAL(7,2);  7 digits max length, 2 precision. do not want them to put in sign
            array('amount_paid', 'DecimalValidator', 'm'=>7, 'n' => 2, 'want_sign' => false), 
        );
    }
