Thank you, that’s exactly the sort of plugin I’ve been looking for throughout the past days. It perfectly works.

Sorry, a recent WordPress upgrade caused a bunch of my files to become detached from the posts they belonged to. I think I have them all fixed now, but this one is definitely fixed.

Plugin could not be activated cause it triggered a fatal error:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /home/www/blog.agnitio.es/wp-content/plugins/wp-authenticate.php on line 23

Fresh new install of WP 2.3.3

Worked fine in WP 2.3.2 and still working in an upgrade to 2.3.3, but the error happened in a new install.

Please help.

Alfredo: Are you sure nothing else changed? It looks like you are getting an error that is usually associated with trying to run PHP 5 code on PHP 4. The plugin (as with everything else I do) requires PHP 5.

Aaron D. Campbell

om gargatte: That could be done, but this plugin does not do it. Consider putting a check in your theme’s page.php file that looks like this:
< ?php if (777 == the_ID()) {auth_redirect();} ?>
Replace “777″ with the ID of the page you want to require authentication for.

its just too kind of u to have replied.

hey, i ‘m not able to make it work:(
its not doing de intended job, i mean it just allows everyone to view de page

Aaron D. Campbell

If the code is showing up, make sure it’s wrapped in php tags:
< ?php ... ?>
Other than that, what version of wordpress?

Steve

I also got the “Plugin encountered fatal error” when I tried activating the Authenticate plugin. After reading here that you’ve converted all your plugins to PHP 5, I switched my WP 2.3.3 installation to run on PHP 5. Thereafter the plugin and the rest of the blog is working fine.

Suggestion: If the plugin requires PHP 5 to run at all, please indicate this up front in the README.TXT file and other documentation.

Thank you for your work.

Thank you for creating this plugin. FYI - I am using it successfully with Wordpress 2.5.

Aaron D. Campbell

Thanks for the update Ian, I tested it with 2.5.1 to make sure, and then fixed the readme in the repos to reflect that.

George

There is a problem running this plugin on WP2.5. As reported elsewhere, if you upload an image, WP shows the login box in the box after upload, instead of the image. Any ideas, as I would like to revert to usin this plugin?

Chad
April 25, 2008

I downloaded the plugin a few minutes ago and installed it on WordPress 2.5.

2 small issues:
Line 29: auth_redirect(); is commented out. It must be uncommented to actually work
Line 7: Version is still listed as 1.0

Otherwise, it DID work with WordPress 2.5!

Thanks Aaron.

[...] force WordPress to require a login, we used the Authenticate plugin. So, the only real work we needed to do was to create a system that forces the user to use [...]

So, this plugin doesn’t seem to work on 2.6. Any suggestions?

Paul
July 15, 2008

BTW- the problem seems to be that WP 6 changed how cookies work, it that helps point out the solution.

Frederik
July 17, 2008

Do the following to make the plugin work with Wordpress 2.6:
Change these to lines:

$user = wp_signon();
if ( is_wp_error($user) ) {

to this line

if ( !is_user_logged_in() ) {

Frederik
July 17, 2008

Should say “these two lines:”

Sly
July 17, 2008

Maybe I am blind but I can not see these two lines in the wp-authenticate.php .

Mike P
July 17, 2008

Frederik, the change you suggested worked like a charm…

Thanks

July 18, 2008

In my case, I modified wp-authenticate.php by this:

if ((strpos($_SERVER['PHP_SELF'], ‘wp-login.php’) === false) && (strpos($_SERVER['PHP_SELF'], ‘wp-register.php’) === false)) {
if ( !is_user_logged_in() ) {
auth_redirect();
}
}

Then, it works with WP 2.6.

July 19, 2008

Thanks a lot bread. It’s working now :).

Michael Hubbard
July 23, 2008

I made the change that bread suggested, and I’m now getting the following error:

Parse error: syntax error, unexpected T_STRING, expecting T_FUNCTION in /[site]/wp-content/plugins/wp-authenticate.php on line 35

Any suggestions?

Ben
July 23, 2008

Hopefully this will help:

Look at this code here:
if ((strpos($_SERVER['PHP_SELF'], ‘wp-login.php’) === false) && (strpos($_SERVER['PHP_SELF'], ‘wp-register.php’) === false)) {
auth_redirect();
}

Now, Make it look like this:

if ((strpos($_SERVER['PHP_SELF'], ‘wp-login.php’) === false) && (strpos($_SERVER['PHP_SELF'], ‘wp-register.php’) === false)) {
if ( !is_user_logged_in() ) {
auth_redirect();
}
}

that should clear it all up, doing this made it work like a charm for me.

Jeff
July 24, 2008

After applying Ben’s suggestion, I cannot activate the plugin in WordPress 2.6

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’ in /hermes/bosweb/web031/b313/sl.adejeffc/public_html/blog/wp-content/plugins/wp-authenticate.php on line 23

line 23 = “public static function check_auth_to_read () {”

Sly
July 25, 2008

Lack of “}”. Check carefully your edited plugin.

Mikael Hugo
July 27, 2008

If you get it to work it would be nice that you post the entire code.

theChad
July 28, 2008

Here is the full code. The final issue I had was incorrect single quotes around the .php file names.
I took the liberty of updating the version number and the links.

theChad
July 28, 2008

hmm… i guess the tags don’t work.

Mikki

Can you post it somewhere else?

Jeremy Stein
July 30, 2008

If you get this error:

Parse error: syntax error, unexpected T_STRING, expecting T_OLD_FUNCTION or T_FUNCTION or T_VAR or ‘}’

It’s because you have an older version of PHP. You can fix it by removing “public static” from the code.

My problem is that I get a redirect indefinatley.

Croila
August 7, 2008

I get an indefinite redirect too, and I’m using WP 2.6, and PHP4.

If anyone can help out here and let us know how to get this working, that would be really great!

@Crolia - Make sure the ‘’s are not ´´

Got the infinite redirect as well but on WP 2.6 and PHP5

Look at the ‘… There was a problem with it…
The correct file that works with 2.6:

Are you going to release a new version of this useful plugin? It’s not working for me on 2.6.2

aaawww
October 1, 2008

I’ve also added as non-auth condition the upload page of the new flash uploader, to make it work with 2.6.2

if
(!(!(strpos($_SERVER['PHP_SELF'], ‘wp-login.php’) === false) || !(strpos($_SERVER['PHP_SELF'], ‘wp-register.php’) === false) || !(strpos($_SERVER['PHP_SELF'], ‘async-upload.php’) === false)) ) {

(i’ve had to reverse the demorgan done on the two original strpos)

Блин, ЗАЧЕТ! Полностью поддерживаю! Жаль, заметил, в преддверии наступающих новогодних праздников интернет несколько обеднел на посетителей и, соответственно, на хорошие идеи тоже, а тут такое! Уважаю. А я вот сижу в нете днями, друзья разом махнули новый год встречать за бугор, а я не смог из-за сессии

Огромное спасибо за информацию, это действительно стоит иметь в виду, кстати, нигде не мог ничего толкового на эту тему в нете нарыть. Хотя в реале много раз сталкивался с тем, что не знал, как себя повести или что сказать, когда речь заходила о чем-нибудь подобном.

Полностью с Вами согласен, я давно уже пришёл к такому мнению.
ПС: Всех с наступающим Новым Годом. Всем хороших подарков и побольше, а то меня так на прошлый новый год только не в качестве вирусов угораздило, так “удачно” одарили, что без компа мог остаться, если бы не помощь добрых людей опять же из интернета.
