I have a multidimensional associative JavaScript array with some metabox data and I need to store that array in the WordPress database (in a single column).
And I also want to get that stored array back in the metabox call back function and use the values in the array to populate the relevant fields.
This is what I've done so far...
var data = [
{ key: 'cardK', val: 13 },
{ key: 'cardQ', val: 12 },
{ key: 'cardAJ', val: 11 },
];
var serializedData= JSON.stringify( data );
This outputs a string look like this
[[1,2],[3,4],[5,6]]
Now I can store this in the DB in a single column. But how can I get this back as an array and use it to populate the fields ?
