I am in need of a WordPress plugin written (PHP5) that simply provides an interface to the following:
1. Select target categories from the list
2. Select by author (All Authors or individual author)
3. Select custom fields to export (Provide List of Custom Fields)
4. Click button Export to CSV (Excel)
This is very straight forward and similar to WordPress's current export tool (with the exception to filtering by categories and the inclusion of the custom fields)
Regarding custom fields, it will be the same query found in the "Custom Field" Drop down when you create a new post (/wp-admin/[url removed, login to view]) however it should be checkboxes rather than a drop down.
I would be interested in hiring you for a second job which would be to then upload the posts back similar to [url removed, login to view] but with less options but we can discuss that for a second project.
