entity number formating in phalcon form volt

Problem :

I want to render form text with formatting value.

Case

[input:text] // this is text input

[5000] // this is my text input without number_format()

[5.000] // this is my goals

Code :

$protQty   = new Text('protQty',[
    'placeholder'   => 'Jumlah Pesan ( Hanya Angka ) ',
    'class'         => 'form-control ',
    'value'         => number_format($entity->protQty,0,",","."), //unworking code
    'readonly'      => true
]);
$protQty->setLabel('Jumlah Permintaan');
$this->add($protQty);

You should modify the entity. Field value is overwritten if entity is available.

Do the following:

$entity->protQty = number_format($entity->protQty, 0, ",", ".");

$protQty = new Text('protQty',[
    'placeholder' => 'Jumlah Pesan ( Hanya Angka ) ',
    'class' => 'form-control ',
    // Not needed anymore
    // 'value' => number_format($entity->protQty,0,",","."), //unworking code
    'readonly' => true
]);

Other option would be to use getters/setters in your model to always output the data in the desired format.
