Currency (price) formating on custom fields

admin管理员组

文章数量:1122846

I need to format a custom field in admin area (post edit) as a currency, eq: 12.000,00 , with user typing only the numbers, the , and . automatic. Ive searched arround, with no sucess.. Anyone? thank

The code i am trying to use to enqueue script in admin is

function enqueue_admin() {

    wp_enqueue_script( 'jquery' ); //adding Jquery to admin. Not sure if is needed or already there
    wp_register_script( 'autonum', THEME_DIR . '/js/vendor/autoNumeric.js', array( 'jquery' ), '1', false ); //this is autoNumeric for currency format
    wp_enqueue_script( 'autonum' );

}
add_action( 'admin_enqueue_scripts', 'enqueue_admin' );

Also, not sure if i need to change all the $ to JQuery in autoNumeric.js, because of wordpress compatibility

• How are you wanting this to work? Are you talking about dynamic reformatting as the user types? – s_ha_dum Commented Jan 21, 2013 at 22:46

Sorted by: Reset to default 2

if you want to process the field after submitting, php's number_format function is what you need:

$price = number_format( $number, 2, '.', ',' );

but if you want to change how the number is displayed as it's typed in, try jQuery autoNumeric

Autonumeric is a jQuery plugin and looks to be written so that you don't have to swap out the $.

I think the problem is this line:

wp_register_script( 'autonum', THEME_DIR . '/js/vendor/autoNumeric.js', array( 'jquery' ), '1', false ); //this is autoNumeric for currency format

The problem is that I am not sure where THEME_DIR is coming from. That constant is not defined on my test install. I suspect that you have a broken URL for that script.

At any rate, even if THEME_DIR is defined and I just missed it, instead of that constant you should probably be using get_template_directory_uri() if this is a standalone, or parent, theme or get_stylesheet_directory_uri() if it is a child theme.

You can also use the WordPress function number_format_i18n which use the user locale to format the value.

echo number_format_i18n($number, 2)

Also, DO NOT USE the PHP money_format function because it is marked as deprecated in the PHP documentation.

I think is better, that you add with a plugin a meta box for your price field. There is easy to filter and format the output. The sore inside the database and it is easier to maintance or add the values inside the field for authors. For read, get output the value can you also use the default functions of custom post type. It give many tutorials and answers on WPSE to this topic.

For the format with php it is easy, if you use the money_format() function.

• A example: echo money_format('$%i', 3.4); // echos '$3.40'

I think this function is the right way. The function use the locale var from the WordPress install and and works with different types and languages. A format with the default php functions is not usable for longer time, is the hard way to format in this context.

If you like a way in javascript, then see on this WPSE thread, very helpfull. But I think, the php way is fast and easy for a output inside a custom field, like in a Meta box.
