I don't know how to fix it, somebody can tell me, please. best regard

Answer 1

You are using single quotes (') for your data-options value, but you are also using them for the keys in the JSON string inside. You could fix this by using double quotes for the attribute value instead, escaped (\"), because you're in the echo string. If this is not the main cause, it's at least a significant problem.

@Spectarion also brought my attention to the fact that your JSON-like string is not valid JSON, so you will likely run into problems, if you're going to parse it using a JSON parser. JSON requires double quotes and all keys must be quoted.
