I have came across the WordPress logout error several times but I really never figured out the cause of it. In earlier days, it was generally that I was missing a nonce but now even with logout link generated by wp_logout_url();, I am greeted with the WP die screen:
Im creating a visit/page views counter with ajax,jquery and php, I have been reading a few articles that recommend the use of nonces for data manipulation through ajax, however i am not sure if i need to integrate the use of nonces for my simple counter?
This is probably a noob question BUT hear me out – isn’t the point of using Nonce to protect from things like scrappers (phpcurl scrappers etc.)? But my Nonce prints out in the head of the document like so:
for a personal plugin (nothing going to the public or commercial), I built an AJAX form and its endpoint is a custom endpoint (REST Api).
I’m currently working on the admin page of my custom post type, and I got stuck on deciding whether to add a nonce field again for the second metabox or not. I’m very new to custom post types, and searching online about this doesn’t really yield that many results.
What is the difference, which one should I use?
A nonce is a “number used once” to help protect URLs and forms from
certain types of misuse, malicious or otherwise. WordPress nonces
aren’t numbers, but are a hash made up of numbers and letters. Nor are
they used only once, but have a limited “lifetime” after which they
expire.
I’ve seen a couple of discussions about getting WordPress to regenerate a unique nonce for subsequent Ajax requests, but for the life of me I can’t actually get WordPress to do it– every time I request what I think should be a new nonce, I get the same nonce back from WordPress. I understand the concept of WP’s nonce_life and even setting it to something else, but that hasn’t helped me.
I can see that wp_nonce_field generates a value in the hidden field.
