I have a site that allows to apply online. I have created the front-end form and that works ok.
As part of the form I ask users for their email address and automatically populate post they are applying.
i want to do if user already appyed that perticular post then don’t allow again and again for the same post
any soluiton plese
You’d have to require unique values for a field, this will only work if the application is somehow saved as a “post” in WP
