I have a site with two type of user role, administrator and author.
I have a dive class name "site-shop-wrapper" which I want to show only to posts added by the administrator and hide it for all other posts added by authors.
So basically I need a function to check the post author role and if it was not an administrator, then remove the div by class name.
I am new to WP and don't know much about it, any help with bee appreciated.
Basically you are asking a function to check the post author role. You can use user_can() function.
if(user_can('administrator'))
{
//Write your code if the admin
}
current_user_can() : https://codex.wordpress.org/Function_Reference/current_user_can
user_can() : https://codex.wordpress.org/Function_Reference/user_can
Finally, I decided to use if author_can function. However, I believe there is a better way of doing this.
add_action('wp_footer', 'remove_buybutton_from_non_admin');
function remove_buybutton_from_non_admin(){
if (author_can($post->ID, 'activate_plugins')) {
?>
<script>
var appBanners = document.getElementsByClassName('shop-wrapper'), i;
for (i = 0; i < appBanners.length; i += 1) {
appBanners[i].style.visibility="show";
}
</script>
<?php
}
else {
?>
<script>
var appBanners = document.getElementsByClassName('shop-wrapper'), i;
for (i = 0; i < appBanners.length; i += 1) {
appBanners[i].style.visibility="hidden";
}
</script>
<?php
}
}
This is not that difficult to achieve. First, get an array of all admins:
$admins = get_users (array ( 'role' => 'admin'));
This returns an array of user objects. You will need an array of admin ids, so you'll have to extract those:
$admin_ids = array();
foreach ($admins as $admin) {$admin_ids[] = $admin->ID;}
Next, see if the current user is in the $admins list and act accordingly
$author_id = get_the_author_meta( 'ID' );
if (in_array ($author_id, $admin_ids))
...do admin stuff...
else
...do non admin stuff...;
Note: I didn't test this code, some debugging may be necessary.
