Create redirection to random post system

  • Hello,

    I hope everyone is safe.

    Ok, so I need a little advice.
    Basically, I have a blog in which I would like a button that will lead to random posts of my WP website. But I also would like to give the choice to my visitors to filter for what type of posts (by the category type) they would get random posts.

    For example:

    Let’s say that my blog have 5 categories of posts: dog, cat, bird, fish, wolf.

    We will have the “Random” button, and next to it, a choice by checkbox for each of these 5 categories. If the user check the box for “dog” and “cat” only, after clicking the “Random” button, a random post only from the “dog” or “cat” category will be loaded. Not “bird”, “fish” or “wolf”.

    Currently, I temporarily set 5 random buttons, one for each category. If I click on the one associated with the “dog” category for example, a random post from the “dog” category will appear. So of course, I would like to replace that system with one button only, and the 5 checkbox.
    Preferably, I would like the script to FIRST randomly choose one of the category for which the checkbox have been checked. And SECONDLY, to randomly choose a post for this category.

    Here is the code I have for the 5 buttons.
    Can you help me modify it to replace it with the checkbox system and one “random” button?

    (NOTE: I am using the plugin “Redirect URL to Post” to generate the url redirecting to a random post)

    
[su_button url="https://website.com/?redirect_to=random&cat=2" style="flat" background="#2D9600" size="20" center="no" rel="nofollow"]DOG [/su_button]
<br>

[su_button url="https://website.com/?redirect_to=random&cat=5" style="flat" background="#2D9600" size="20" center="no" rel="nofollow"]CAT [/su_button]
<br />

[su_button url="https://website.com/?redirect_to=random&cat=6" style="flat" background="#2D9600" size="20" center="no" rel="nofollow"]FISH[/su_button]
<br />

[su_button url="https://website.com/?redirect_to=random&cat=7" style="flat" background="#2D9600" size="20" center="no" rel="nofollow"]BIRD [/su_button]
<br />

[su_button url="https://website.com/?redirect_to=random&cat=8" style="flat" background="#2D9600" size="20" center="no" rel="nofollow"]WOLF [/su_button]
<br />

    I hope my explanation was clear.

    Take care.

    Do you use a plugin already to build forms on your site ? If so, which one?
    Gravity simply rocks bc it’s very mature, and they have extensive hooks and actions so that the base code does a lot of the heavy lifting upfront.

    WP Jobs is a good place to look – the forums are not usually place to solicit paid gigs. ??

    No I don’t have a plugin to create forms. Gravity seems very good indeed. Is there a free alternative we could use?

    Yes, I know this isn’t the right place to solicit developers, but since you seemed knowledgeable to me and my usual developer stopped working because of the current global situation, I made an exception. Let me know if you are interested. Otherwise, I’ll check on jobs.wordpress.

    Ya, there’s load of forms.
    WP Forms, Ninja Forms, Caldera forms.
    Not sure if any of those ones let you write hooks on the action though tbh.

    NO problem. I installed Gravity Form now. Can you give me a step by step for how you configured thing with Gravity (the version with redirection to the random post, not the random list of article) so I can try to reproduce all of that.

    I am not a good coder, so please explain to me like if I was three-years-old :).

    You need to alter the action after the user hits submit – Gravity has this built in :
    https://docs.gravityforms.com/gform_after_submission/

    – user selects categories using the checkbox
    – onSubmit, put the category IDs into an array
    – loop through the array
    – within the loop, call another function the takes in post type :

        'post_type' => 'post',
    'orderby'   => 'rand',
    'posts_per_page' => 20,
    'category__in' => ($value),
    );

    category__in is native to WordPress :

    My while loop output the links to the random posts as you saw, but you could just output the_content, and limit it to 1 post.

    It’s pretty straight-forward, and sits in the functions file of your child theme.

    Great! Thank you very much. I am not sure I’ll be able to perform these tasks, but I’m going to get to it and try to set this up.
