I want to know if someone can make a specific job
I got a site with a landing page, in this page I got a default comment form of WordPress but...
- I need where each commenter only can post one comment.
- I need to disable comment form if custom meta value and email exists in database of WordPress
- If email and custom meta value exists put error message, if meta value exists put a thank you message instead of submit button
- I need to check this via AJAX and if custom meta value not exists put the new comment in top of list of comments
- No need a plugin for this
How much cost this job?
Thanks in advance
