Adding an additional search field to the header search
Hi, I am looking to add an additional text input search box to the header search (please see attached image). This isn't going to be used for a traditional 'Job' website. An example of what I would like to happen is this; A user can search for what they are looking for and also what they are offering in addition to their location. However if they did an independent search for just what they are 'offering' OR what they 'need' - this would still return them a result based on the functions below.
I would like the end result to achieve:
1. The 'I'm Offering' input box (see image) to carry out a normal search on all submitted jobs as normal.
2. The 'I Need' input box to do an additional search on what is currently the 'How to apply' text field (Used when someone adds a new job post) - This data is found in the wp_postmeta table (_how_to_apply)
3. The Location text input box (and radius filter) to remain the same.
Would very much appreciate if someone could help me with this request or point me in the direction of someone who could help. Thanks
