Code

PHP

<?php

$tea_content = array(
    array(
        'type' => 'Code',
        'title' => 'How do Penguins code their icebergs?',
        'id' => 'my_code_field_id',
        'default' => 'With a frozen bug.',
        'rows' => 4,
        'description' => 'A simple question to know if you know how to seduce a penguin.',
    ),
);

NB: a big thanks to readme.io for the design inspiration :)

Retrieve data

Using the _get_option('my_code_field_id') method, you'll get (with a json_encode() display):

JSON

{
    "mode": "text\/javascript",
    "code": "\/**\r\n * TEA CODE FIELD\r\n *\r\n *\r\n * To add this field, simply make the same as follow:\r\n * array(\r\n *     'type' => 'Code',\r\n *     'title' => 'How do Penguins code their icebergs?',\r\n *     'id' => 'my_code_field_id',\r\n *     'std' => 'With a frozen bug.',\r\n *     'rows' => 4,\r\n *     'description' => 'A simple question to know if you know how to seduce a penguin.'\r\n * )\r\n *\/\r\nvar tea = 'Here it comes';"
