Hi Priyanka Y., I noticed you've made a similar job I need ([url removed, login to view]).
I only need to have a DB-update using $wpdb->update. There is only one field to be updated, the data needs to be read from an input field, update shall be made using jQuery/AJAX (no reload of page).
I already read the present content of the db field using $wpdb->get_col in a data list of this input field.
Should be a very simple job for you, therefore i stick to the price of USD15, which is the same as for the other job (-> link above) you've made.
Please confirm asap.
