Restrict certain user roles from making purchases in Woocommerce - php

Question

No matter how many ways I try, I can't get it to work. I must mention that I have used this snippet for other purposes, such as restricting the possibility of buying if the product contains a certain tag or a certain category.
But to do this based on the user role, I just haven't been able to pull it off. I remember this did work like a couple of months ago, but now, it just doesn't work anymore. Is there something I'm missing?
add_filter('woocommerce_is_purchasable', 'modo_catalogo_por_rol_usuario', 10, 2 );
function modo_catalogo_por_rol_usuario( $is_purchasable, $product ) {
$user = wp_get_current_user();
$catalog_roles = array('cliente_empresa_limited', 'cliente_modo_catlogo', 'administrator'); //add your user roles here
$roles = ( array ) $user->roles;
$is_purchasable = true;
if ( in_array( $catalog_roles, $roles ) ) {
$is_purchasable = false;
}
return $is_purchasable;
}

Answer 1

The following code will restrict the ability to purchase products based on user role. The user roles cliente_empresa_limited, cliente_modo_catlogo, and administrator will be able to purchase without restriction:
/* Restrict the ability to buy products based on the user role.
Roles 'cliente_empresa_limited', 'cliente_modo_catlogo',
and 'administrator' will be able to purchase */
function modo_catalogo_por_rol_usuario(){
$user = wp_get_current_user();
$user_meta=get_userdata( $user->ID );
$user_roles=$user_meta->roles;
if ( ( in_array( 'cliente_empresa_limited', (array) $user_roles ) ) || ( in_array( 'cliente_modo_catlogo', (array) $user_roles ) ) || ( in_array( 'administrator', (array) $user_roles ) ) ) {
return true;
}
else {
return false;
}
}
add_filter( 'woocommerce_is_purchasable', 'modo_catalogo_por_rol_usuario' );
Add the code above in functions.php file of your active child theme or active theme. It is tested and it works.

You should use array_intersect which will return an array of matches between two arrays. If the count is greater than 0, then it will be true.
add_filter( 'woocommerce_is_purchasable', 'modo_catalogo_por_rol_usuario', 10, 2 );
function modo_catalogo_por_rol_usuario( $is_purchasable, $product ) {
$user = wp_get_current_user();
$catalog_roles = array( 'cliente_empresa_limited', 'cliente_modo_catlogo', 'administrator' ); // add your user roles here.
$roles = (array) $user->roles;
if ( 0 < count( array_intersect( $catalog_roles, $roles ) ) ) {
$is_purchasable = false;
}
return $is_purchasable;
}
