Disable profile editing for one single account - php

Question

I have made a public account in wordpress which I will send to 100 users.
So the login would be:
Username: public
Password: 123example
The only thing I want is to hide the profile page for this specific user account so they can't change password, emailadress, etc.
How to achieve this? Maybe change some php?

Answer 1

The last portion in #aSeptik's answer could be a little more WP friendly.
function force_profile_redirect() {
global $pagenow, $current_user;
get_currentuserinfo();
if ($pagenow == 'profile.php' && $current_user->user_login == 'public') {
wp_redirect(home_url());
}
}
add_action('admin_init', 'force_profile_redirect');

this script cover all the aspects of the question, read the code comments for further explanation.
<?php

return home_url();
}
else {

}
}
add_filter('login_redirect', 'redirect_user_to', 10, 3);

Answer 3

You'd need to modify your profile page code, to make it not show the editable areas, and not run the "update profile" action, if the user ID is [xyz].
For the page which actually does the updating of the profile, you can just put at the top something like
// Change this line to match however you identify your logged-in user
// And change the id number to the ID of the public user
global $current_user;
get_currentuserinfo();
if ($current_user->ID == 1)
{
// Stop them seeing this page
header('Location: index.php');
// And for good measure
die();
}
For the page on which they can change the profile fields before they submit the form, you can do something like this
// Change this line to match however you identify your logged-in user
// And change the id number to the ID of the public user
global $current_user;
get_currentuserinfo();
if ($current_user->ID == 1)
{
// Say no
echo '<p>You cannot edit your profile on this account.</p>';
// And for good measure
die();
}
Without seeing your code, it's hard to be more specific, but this should work at a push, even if it's not exactly how you want it to work.
