Page Restriction (18 posts)

    Because I’m using WordPress as a Content Management System for our up-coming intranet/web-app at work, I needed a way of keeping the regular folks out of our private section of the site.

    So, I wrote this plugin - Page Restriction - and it does just what it says, pretty much. It will add an Administration panel under the Options section, entitled Page Restriction - Clever huh? There you can pick and choose whatever pages you want restricted to logged-in users.

    I just finished it today, so it could be a little buggy - though it works exactly how I want it to for me. I'm on WordPress 1.5.1.3 and I haven't yet tested it on any other version, though I suspect it will work just fine with all the 1.5.x versions.

    You may download the source here: http://17thdegree.com/wp/page-restriction.phps

    Feel free to comment here or on my site (which is in shambles right now, I appologize).

    Hi everyone

    I'm having problems with this plugin - you can read the background here - http://17thdegree.com/archives/2005/07/01/wordpress-plugin-page-restriction/ (I'm Mary-Ann Horley in the comments) and I thought I'd see if people here had any ideas.

    I'm getting several of these

    Warning: Cannot modify header information - headers already sent by (output started at /home/kartlink/public_html/pro/wp-content/themes/gentle_calm/header.php:5) in /home/kartlink/public_html/pro/wp-includes/pluggable-functions.php on line 109

    when I'm logged out and try to look at a page I've restricted. I'm on 1.5.1.3 and I've also got EZStatic and Tiger Admin installed, and disabling EZStatic doesn't make a difference

    That's an odd error in that file, and although the link above would generally work for the 'headers' error, it might not here. Could you try it ?

    I've just got up, so I'm probably not thinking clearly yet, but is it header.php that I should replace with a new one or pluggable-functions.php?

    Forgot to say, but I've already tried trying a different theme with no results, so I don't think it's a problem with the header

    If you copied and pasted the source for the plugin, it's possible you have an extra space somewhere, most likely at the end of the file. Check your plugin file in the text editor and make sure there's not any extra spaces.

    OK, read the Codex properly now and I can't find any whitespace on the lines the error is complaining about in pluggable-functions.php, but I don't really know what should be there and what shouldn't

    It would be at the end of the file, most likely. I'd try looking at the page restriction plugin file also, considering that's the one you copy and pasted, unless I'm misunderstanding ,and pluggable-funtions is the page restriction plugin.

    I just had a look and I can't see any whitespace at the end of either file. I'm on a Mac so no proper delete key which scuppers the instructions in the Codex for making sure, waah.

    page-restriction.php is the plugin, but I just downloaded it and uploaded it to my webspace, I didn't open it aat all

    And you say this error occurs even with a different theme? What's the line number with a different theme than gentle calm?

    On Gentle Calm, it's doing it on lines 109, 110, 111, 112 and 114 and on Default/Kubrick it's the same.

    Just deleted and reinstalled/activated the plugin and I got something similar in the admin. Here's a screenshot: http://www.kartlink.com/pageerror.gif

    Someone else in the plugin page comments had that on activating though and the author said it wasn't anything to worry about.

    I don't get any options to add/administer page restrictions. I do however have the Page restrictions link under my options link.

    there's a screenshot here: http://www.p166.com/odd/pers.jpg

    Regarding the post above, that's exactly what I had the first time around that I activated the plugin then after that it it ran without any more errors.

    I've updated this plugin. It fixes the initial db error.

    Kartlink - could you see if you have any more problems.

    dakleton - I'm not sure why you don't see anything, the only reason you wouldn't see anything is if you didn't have the function add_options_page() in your wp-admin/admin-functions.php file.

    Also, I just released another plugin that works in conjunction with this one called Page Access.

    I get almost the same problem as kartlink and I've posted some background on your blog comments as well.

    I am using this plugin in conjunction with Page Access, but it doesn't work by itself either.

    The errors I get when used with Page Access are:

    When I am logged in as a user without access privileges for the page:

    code
    WordPress database error: [You have an error in your SQL syntax near '; ' at line 7]
    select distinct page from wp_page_access_group_line_item inner join wp_page_access_user_line_item using(group_id) where wp_page_access_user_line_item.user_id = 1 order by page;

    Warning: Invalid argument supplied for foreach() in /home/virtual/site14/fst/var/www/html/wp-content/plugins/page-restriction.php on line 221

    Warning: Cannot modify header information - headers already sent by (output started at /home/virtual/site14/fst/var/www/html/wp-content/themes/default/header.php:5) in /home/virtual/site14/fst/var/www/html/wp-includes/pluggable-functions.php on line 129
    code

    When I am not logged in:

    code
    Warning: Cannot modify header information - headers already sent by (output started at /home/virtual/site14/fst/var/www/html/wp-content/themes/default/header.php:5) in /home/virtual/site14/fst/var/www/html/wp-includes/pluggable-functions.php on line 109

    code

    When I use Page Restriction by itself, I get the above error as well.

    I've tried both WP 1.5.1.3 and WordPress 1.5.2, neither solves the problem. WordPress and other plug-ins run perfectly, so that's why I am wondering if this is due to something in the Page Restriction script.

    I am using MediaTemple.net as my host.
    Apache: 2.0.46
    PHP: 4.3.10
    MySQL: 3.23.58

    Their PHP runs in safe mode (http://www.php.net/manual/en/features.safe-mode.php), I don't know if this has anything to do with the problem but at a quick glance it shouldn't.

    I have been able to run an identical installation successfully at another host with Apache 1.3.31, PHP 4.3.9, and MySQL 4.1.12.

    Ok, I think I solved it. Not sure if I'm implementing the fixes "correctly," but everything works now.

    To fix:

    WordPress database error: [You have an error in your SQL syntax near '; ' at line 7]
    select distinct page from wp_page_access_group_line_item inner join wp_page_access_user_line_item using(group_id) where wp_page_access_user_line_item.user_id = 1 order by page;

    Find this part in page-restriction.php:

    select distinct page
    from wp_page_access_group_line_item
    inner join wp_page_access_user_line_item
    using(group_id)
    where wp_page_access_user_line_item.user_id = $user_ID
    order by page;

    Put the above part all on one line so it looks like:

    select distinct page from wp_page_access_group_line_item inner join wp_page_access_user_line_item using(group_id) where wp_page_access_user_line_item.user_id = $user_ID order by page;

    To fix:

    Warning: Invalid argument supplied for foreach() in /home/virtual/site14/fst/var/www/html/wp-content/plugins/page-restriction.php on line 221

    Find this line in page-restriction.php:

    foreach ($pages as $k => $v) {

    Change it to:

    foreach ((array)$pages as $k => $v) {

    Finally, the infamous header error:

    Warning: Cannot modify header information - headers already sent by (output started at /home/virtual/site14/fst/var/www/html/wp-content/themes/default/header.php:5) in /home/virtual/site14/fst/var/www/html/wp-includes/pluggable-functions.php on line 129

    Remove this line from page-restriction.php (near the end):

    add_action('wp_head', 'check_the_user');

    Open your theme's header.php and put this before everything, make sure there are no spaces/tabs/lines before it:

    <?php check_the_user(); ?>

    Note, becareful if you're using Notepad, apparently it puts 3 lines above the first line that you see... If it says the problem is on header.php line 4 after you do it, then open up the file in Wordpad and delete the 3 lines above it.

    Hope this helps.

    Dear Sir,

    Where can I set the no_access_page?

    Sincerely,
    Helge

    Solution to MY problem:

    in WordPress 2.0.4 This plugin gave me horrible blank screen until I read up on documentation and changed the line before last to look like this:

    add_action(/*'wp_head'*/'template_redirect', 'check_the_user');

    You can see what was there before - I just commented it out.

    Basically, it was using the wrong hook and trying to redirect you away from a page AFTER it would already send out its headers.

    Enjoy!

    To andrabar.
    Thanks That worked.
    Is there anyway to get it to redirect to a page that tells the user that he/she must register rather than the login page?
