Trying to get both the hex and RGB value of a color from the native color picker in Wordpress, user chooses the color via a custom metabox in the admin. Just need to save both values as meta for re-use in the interface.

jQuery(function() {

Any feedback would be greatly appreciated. TXS.

  • You can get the RGB value via the change event: change: function ( event, ui ) { var rgb = ui.color.toCSS( 'rgb' ); ... } - see the "Advanced usage" section here and the Color.js docs.

Thanks for your help Sally, here is the completed jQuery which pushes the RGB value to another field. Name of the RGB field has _rgb at the end.

jQuery(function() {
    var myOptions = {
        // you can declare a default color here,
        // or in the data-default-color attribute on the input
        defaultColor: false,
        // a callback to fire whenever the color changes to a valid color
        change: function(event, ui){
            var rgb = ui.color.toCSS( 'rgb' );
            var name = jQuery(this).attr("name");
            name = '#' + name + '_rgb';
        // a callback to fire when the input is emptied or an invalid color
        clear: function() {},
        // hide the color picker controls on load
        hide: true,
        // show a group of common colors beneath the square
        // or, supply an array of colors to customize further
        palettes: true

And here is what the custom field looks like below the color picker field.

<input type="text" name="destination_secondary_color_rgb" id="destination_secondary_color_rgb" value="<?php echo get_post_meta($post->ID, 'destination_secondary_color_rgb', true); ?>" />
  • PS: You should escape dynamic values, and for input fields, you can use esc_attr() - e.g. <input name="foo" value="<?php echo esc_attr( get_option( 'foo' ) ); ?>"> :)
