Magento code adding custom options in product

Which was used in one of my projects to import product data including custom options. Another solution would be writing a script which could dynamically add custom options to a set of existing products. In this post I will show you how to create such script.

The available properties are as follows:

• title – the option’s label;
• type – option type, possible values:
  • field – simple input text,
  • area – multiline text area,
  • file – file with an upload form in the front-end,
  • drop_down – drop-down list with predefined values,
  • radio – a set of radio buttons,
  • checkbox – multiple selectable checkbox options,
  • multiselect – list of multiple selectable options,
  • date – date input field,
  • date_time – date and time combined,
  • time – time only;
• is_require – a flag indicating if the option is required, 1 or 0;
• price – price surcharge for the option;
• price_type – type of the option surcharge, fixed or percent (of the product’s price);
• sku – SKU for the option.

Some of the properties are type-dependent, e.g., a “file” option also has:

• file_extension – a string of comma-separated file extensions that are accepted by the option; if empty any extension except “exe” and “php” is allowed;
• image_size_x and image_size_y – image dimension limits in pixels;

An option of type “field” can have the following property:

• max_characters – maximum allowed number of characters.

I will demo a example.
I have a json string as below:

$json =
