Wordpress - Password protect a custom post type programmatically

functions.php

<?php
/**
 * Password protects a custom post type programmatically.
 *
 * @param $post
 */
add_action( 'the_post', function( $post ){
	if ( $post->post_type != 'post' ) {
		return;
	}	
	$post->post_password = 'your_password';
} );
?>

Hum, that's odd. I just tried on my end and it works.
Maybe it's a problem with your theme. Try to switch it to Storefront theme for example and check again

Hi ,
I have simple twenty twelve theme, Did you try with custom post type? I have custom post type.

I'm using WooCommerce and I've tried to use the custom post type 'product' and it works just fine.
When I go view the product, the first thing it shows is the password field and I can see no content from the product at all

Hi,
I am trying different ways lets see, anyway thanks a lot

Thank you so much!!

;)

Write the password directly in the code?
How about letting the user set/change password as pages/posts?

Hi @arthurclouds ,

How about letting the user set/change password as pages/posts?

In that case, I believe there wouldn't be necessary to add any code, as this is the default WordPress mechanism when you set a page/post visibility as "Password protected".

Thanks pablo, works great and super useful - we were looking for keeping the same password for all posts to simplify for users and this makes it very easy and programmable.
