I have to use the
meta_query argument so that it checks for a keyword in all available custom field values (in array format) saved for the object. The meta keys are different for every object, therefor I can't use any static key.
This is something I want to achieve.
'meta_query' => array( 'relation' => 'OR', array( 'key' => 'state', // This is where I am lost 'value' => 'mykeyword', //Keyword to look for 'compare' => 'EXISTS' //If keword exists in value (array) ), ),
Can this be done using
meta_query or do I need to use custom database query?
