Write a Wordpress Front end publishing form

Write a Wordpress front-end post form Please read carefully. I want you to write a simple form which the user can submit (and edit) after signing up on the website. Here's how it will work: 1. User signs up on the website and is redirected to the page "My Profile". (this is done by me) 2. This page contains a profile form which has some drop downs, text fields and so on. 3. When the user submits this form, it will create a custom post type. 4. The user can always visit this same page to make changes (the changes will be saved in the same custom post type) 5. When the user visits the page again, the previously entered information should be visible. 6. The form should auto retrieve the user location (country and city). You can use a third party library like ipinfodb for this. Dropdowns The custom post type has some custom taxonomies and custom fields. For custom taxonomy A, I want the following to happen: When the user selects a value from the custom taxonomy dropdown (let's say taxonomy value X), I want the custom text field X to appear. The user should also be able to click on a (plus) button to add another custom taxonomy value A. (see also the attachment) Things to know: 1. The custom post type is created using the CPT UI WordPres plugin. The custom fields are created using the Advanced Custom Fields Pro plugin. 2. Basically, each user can create only one custom post type which contains the profile information. The user can edit the custom post type as much as he wants. 3. The user becomes the author of the custom post type, which is the relation between the user and the custom post type. See also this post on StackExchange [login to view URL]
