pirnt_r($_SESSION) not print all value.
But we log in wordpress admin and preview page when we write print_r($_SESSION) they display all session variable with value.
Thank you.
Can you show us the whole code?
Probable cause:
try print_r($_SESSION) not pirnt_r($_SESSION);
try to put echo before print_r($_SESSION); as in echo print_r($_SESSION);
Wordpress doesn't use session's to log their users in, so if you log in at /wp-admin there are no $_SESSION variables set. Wordpress also doesn't call session_start(). This means you have to start the session yourself if you haven't done so already.
You can do this in the following way:
if ( ! session_id() )
session_start();
If you know the session has not been started already you can use just session_start, like so:
session_start();
If you do this your $_SESSION array should contain the variables you put in it previously.

I'm new to WP development. I need to write a hook to check if the currently logged in user is viewing a post listed within a specific category, and then redirect user if they're lacking certain meta data.
I tried creating this function:
add_action('init','check_user_post_category');
however inside that function I was unable to get the post object (I have tried everything I found on the web!)
global $post; // This object is not valid at this time
global $wp; // $wp->request is empty
$_REQUEST; // This var is giving me an empty array! Is this normal??? :(
Could you kindly suggest, what hook is best to use in this case, and how to get the post object? Many thanks!
Use 'wp' hook instead of 'init'.
add_action('wp','check_user_post_category');
Maybe this would work for you.
As we all know the WordPress' feed url is www.mysite.com/feed.
I have edited the feed-rss2.php file to show thumbnails if a certain GET parameter is passed. See the code below:
<?php if($_GET['c'] == 'detailswiththumb') echo the_post_thumbnail( array(100,100) ); ?>
But when I open the feed address like this:
www.mysite.com/feed?c=detailswiththumb
The code doesn't work. Can the arguments be passed this way? Am I missing something? Please help.
Firstly, the function is get_the_post_thumbnail() not the_post_thumbnail().
Then, their is one more problem in your code, that you have to pass the post id to get its thumbnail (for more info see http://codex.wordpress.org/Function_Reference/get_the_post_thumbnail).
So, first you will have to extract the post id from somewhere and then only you would be able to get the thumbnail. But, I think it would be very tough, so try giving up this thought, for it would take you a lot of time and no living being is going to access that path.
There were browser cache issues. Even with Google Chrome's incognito window. Had to test it with passing fake arguments like...
www.mysite.com/feed?c=detailswiththumb&fakearguments=123
...to clear the cache. And the code is fine.
Sorry for wasting your time guys.
OK it might sound stange but I am facing a good challenge with wordpress.
when echoing the_permalink(); and checking the portfolio pages, I am getting a link something like this:
http://www.domain.com/?portfolio=test
(Where test is the portfolio name).
Is there any option to return the permalink trimmed to ?portfolio=test keeping out the domain url?
While asking, I think I got the answer already (trim()) but I would like to hear your ideas too.
every answer will be much appreciated!
You can obtain the permalink of a post by doing something like so:
<?php
function my_permalink() {
echo substr(get_permalink(), strlen(get_option('home')));
}
?>
The get_option method replaces the deprecated get_settings method, and allows you to retrieve named option values from the database:
http://codex.wordpress.org/Function_Reference/get_option
The 'home' value passed in to the get_option method will return the site URL.
I'm a Drupal nub. I would like to check on every page if user (anonymouse) agreed to somekind of terms. I suppose i should write small custom module ?
Where will this condition be written
if(!$_COOKIE('confirm')){
//jQuery show confirmation form
//Set cookie for 1hour
}
maybee in page.tpl.php ? Please, give me some tips ..
If you don't want to store the info for a long time, you should use $_SESSION variable. Then in preprocess page you could check if the user has accepted and set a variable that you can use in your page.tpl.php.
user_save() accepts an array argument which you can put custom data into. This will then be loaded with your $user object and you can use in any template file.
Check out these modules:
http://drupal.org/project/legal
http://drupal.org/project/terms_of_use
The Legal and TOS modules are good if you need a login. If working with anonymous users, however, you'll need to use the rules module with https://www.drupal.org/project/rules_session_vars.
I'm putting up a site using Wordpress and I'd like to piggyback on its sessions. But I'm not finding any plugins, or even documentation. Any suggestions or references before I start hacking it?
Note: I'm asking about if and how WP uses standard PHP sessions itself, not how to add PHP sessions e.g. using session_start(). Apparently any state WP maintains is accomplished by other means. So if I want to use PHP sessions I need to add and maintain it myself entirely, using techniques like those in the thread.
Thanks all!
It's a very bad idea to modify WP Core files for the ability to use sessions. The best way I've found is to call the session_start() from init action hook.
function kana_init_session() {
session_start();
}
add_action('init', 'kana_init_session', 1);
You can place it in functions.php file of your theme.
Detailed article can be found here: http://www.kanasolution.com/2011/01/session-variable-in-wordpress/
WordPress doesn't appear to call session_start() because it wants to be stateless
and if register_globals is defined, it automatically destroys your $_SESSION
Consider using WordPress Transient API
Values stored using the Transient API are visible to all users, not just the current user, depending on the unique identifier used to retrieve the transient, you could assign each user a unique identifier essentially causing a transient to behave very much like a session.
Further considerations:
Depending on a users setup with object cache, etc., transients may
not always be stored in the DB (e.g. memcached), using transients for
sessions could mean that the data can get bulky and fill memory
quickly (in the use of memcached).
Also, it seems that WP does not do auto garbage collection for
transients:

For what I need to do, the best answer involves:
To allow the cookie for wordpress to persist across subdomains, install the Root Cookie plugin.
sub1.domain.com has wordpress; sub2.domain.com is another site. From the other site (sub2), I read the cookies to identify who the user is and if the user is logged in.
My cookies are as follows:
[wordpress_909bb230b32f5f0473202684d863b2e0] => mshaffer|1255298821|d0249fced9c323835c5bf7e84ad3ffea
[wordpress_logged_in_909bb230b32f5f0473202684d863b2e0] => mshaffer|1255298821|56e9c19541ecb596a1fa0995da935700
Using PHP, I can loop over the cookies, parse the key=>value pairs. These cookies let me know that [mshaffer] has a cookie stored on wordpress, and also is authenticated as logged_in. The expiry of the cookie is 1255298821.
In sub2, I can query the database of wordpress and grab the user info:
SELECT * FROM `wp_users` WHERE user_login = 'mshaffer' ... grab user_id, user_email from this query
SELECT * FROM `wp_usermeta` WHERE user_id = '$user_id' ... grab lots of other data from wp
With this info, I can add to my sub2 session variable / cookie and do what I want with the data. I can identify if I am logged in, and my username ... which let's me grab lots of different data. I can now use WordPress authentication in my sub2.domain.com and redirect accordingly.

Wordpress doesn't seem to use any sessions.
The best way to go about it is to use the action hooks it provides.
Have you checked the solution here this may work for here and its on easy way
http://thedigilife.com/wordpress-how-to-set-session-custom-variable-while-login/
Hooking a function with session_start() on wp_loaded seems to work in this case.
Put this code in wp-config.php at first line:
if (!session_id()) {
session_start();
}
Put this code in theme's header.php at first line:
session_start();
Then it will maintain all session variables.
If you wanna use your own session values, Wordpress does support it.
You need to add following lines at the top of wp-config.php
if (!session_id()) {
session_start();
}
Then add following line at the top of header.php
session_start();
