getting values from mysql database into javascript in wordpress

Question

I am making a wordpress plugin. I am having trouble finding documentation on how to get values from a mysql database into a javascript in wordpress. I have seen examples when people are not using wordpress software, but i'm not sure if there is a better way or a need for better security because it is wordpress.

could anyone post a link to a helpful article or show a example?

Answer 1

You can use JSON to construct data representation in Javascript.

For that, I suggest you use a intermediary PHP page to control ACLs (ie restrict unauthorized access) and construct the JSON data/array.

A simple way to take MySQL data to JSON in PHP: JSON encode MySQL results
