The access rules for each user on page in wordpress

The client wanted to limit the access to certain pages based on user account and password.
So some pages can only accessed by some users that gave them permission the site manager.

For that i create two radio input type with “Yes” or “No” protect page options.When i selected
“Yes” option i can chosen from a list who user has access on page or not.If
i selected “No” option all users have access on page.

I’ve done this in the following code:

echo  '<form action="" method="post">';
echo '<input type="radio" name="protect" '.($protejata == 'Yes' ? ' checked' : '').' value="Yes"> <samp>Yes</samp> 
       <input type="radio" name="protect" '.($protejata == 'No' ? ' checked' : '').' value="No"><samp>No</samp>';
 
	echo '</form>';
	echo '<div>';
	foreach($wpdb->get_results('SELECT ID,user_login FROM cga_users') as $sol_users) {
		echo '<input type="checkbox" '.(in_array($sol_users->ID, $userii) ? ' checked' : '').' name="sol_users[]" id="sol_user_'.$sol_users->ID.'" value="'.$sol_users->ID.'"><label for="sol_user_'.$sol_users->ID.'">'.$sol_users->user_login.'</label>';
	}
	echo '</div>';

I use jquery from hidden list with users when It’s choen “No” protect page option

jQuery(function() {
jQuery('input[name="protect"]').change(function() {
if(jQuery(this).val() == 'Yes') {
jQuery('#xxx').show();
} else {
jQuery('#xxx').hide();
}
});
});

These settings are saved in data base with update_post_meta() function.

update_post_meta($post_id, 'pagina_protejata', $_POST['protect']);
$users = count($_POST['sol_users']) ? $_POST['sol_users'] : array();
update_post_meta($post_id, 'pagina_protejata_users', serialize($users));

In page.php file i tested who user is logged with is_user_logged_in() function.

Finally, there’s another very important peculiarity of what does Cialis that brings it so high above its alternatives. It is the only med that is available in two versions – one intended for use on as-needed basis and one intended for daily use. As you might know, Viagra and Levitra only come in the latter of these two forms and should be consumed shortly before expected sexual activity to ensure best effect. Daily Cialis, in its turn, contains low doses of Tadalafil, which allows to build its concentration up in your system gradually over time and maintain it on acceptable levels, which, consequently, makes it possible for you to enjoy sex at any moment without having to time it.
