If you are looking for wordpress function to check weather user already logged in or not then below code might be useful for you. WordPress provide one single function called is_user_logged_in() that return boolean true for logged in user and false if none of the user logged in.  You can execute different kind of code or display message using this function for logged in user and non logged in users.

Here is an example:

<?php
if ( is_user_logged_in() ) {
// Write your code for logged in user.
} else {
// Write your code for non logged in user.
};
?>

Moreover, you can check level of logged in user and display content based on logged in user roles and capabilities. You can use following code to achieve the same.

<?php
global $current_user;
get_currentuserinfo();
if($current_user->user_level==10) {
 // Put your code here
} else if($current_user->user_level==9) {
 // Put your code here
} else if($current_user->user_level==8) {
 // Put your code here
} else if($current_user->user_level==7) {
 // Put your code here
} else if($current_user->user_level==6) {
 // Put your code here
} else if($current_user->user_level==5) {
 // Put your code here
} else if($current_user->user_level==3) {
 // Put your code here
} else if($current_user->user_level==2) {
 // Put your code here
} else if($current_user->user_level==1) {
 // Put your code here
} else if($current_user->user_level==0) {

BSNL has stopped EVDO and NIC data card booking from last one month. Myself and lot of other EVDO lovers still waiting for the booking to restart. This is more important and awaiting because new EVDO promotional offer rolling out countrywide on BSNL website offering EVDO card @750/month. This is cheapest price bsnl offering in comparison to other telecoms companies. You can expect this kind of things only with BSNL. This is how Sarkari system works. New promotional offer advertisement giving out in media but billing system no longer works from a month. Moreover, promotional offer time is ending on 31st March. It seems new system not going to work soon so nobody will be able to take advantage of this offer.

According to BSNL representative, their new DOT Software system stopped working in the first week of Feb and they have no information on when new system working again. Also, new billing software has lot of issues in billing and booking system. Myself received previous month bill two times with extended charges. It seems new system adopted without proper quality testing by authorities. BSNL employee don’t care what is happening.

Don’t experiment anything if your connection running smoothly and you don’t have specific need. Let me explain why!

There are two incidence happened with me that i never expected. You can not expect this kind of issue with a professional company.

1) I am using BSNL broadband from last 3 years and more. The  reason is i don’t have any alternative in my area. For a year, i used broadband 550 plan and quiet happy with speed and everything. After a year, i feel to change broadband 550 plan to unlimited broadband 999 (Now 750/-) plan due to large volume usage. I reached to BSNL office and give them written application for the change of plan. After one week of application submission my connection stopped working. Initially  i thought there may be a issue with DNS or temporarily server problem. Second day i called customer care and they suggest me to inquire on BSNL new market head office. I reached there and head office representative said to inquire on our area exchange office. Again, i reached my area exchange office but there were only blank chairs saying me why you came here, No body here to attend you. After three visits, i met with my local area office head and what he said was really surprising for me and may be for you too. My connection was cut. They presented me broadband termination order they received from head office. I matched termination order date with the plan change receipt i had. The dates were same. This was simply means they had released connection termination order in place of plan change order. After one week mental and physical practice i got why my connection stopped working and next one week to reconnect my connection. Till date my BSNL bills was paid and i have no due to pay BSNL. How i managed to reconnect my connection is another story. It’s much to learn how  BSNL works.

2) In Jan 2009, they launched new broadband scheme 799 that allow unlimited free calls on BSNL mobile and landline network. I finally decided to take advantage of this offer and again did a blunder mistake. After plan change i received next month bill just doubled. In inquiry, account department said they charged one month price as security deposit. My connection was booked without security deposit and without modem purchase or modem rental under a promotional scheme when i booked my connection 3 years back. The account person said, when plan change or system see any activity in account their software treat account holder as new account holder and add one month plan charge as security deposit in bill if security deposit not already paid by account holder. This is how their system works. After, three years they are charging a loyel customer security deposit even my connection was booked without security deposit. The story not stopped here. As i said, I never paid for modem till now because BSNL were giving modem free of cost at the time of my booking. Let’s see what happen.

Let’s come back to original story. If you have anything to share on BSNL EVDO please feel free to comment so other people take advantage of information.

This error comes when you try to upload media file such as image, video by WordPress browser uploader or flash uploader. WordPress shows this error when temporary upload folder not configured in php.ini file. It is possible upload temp folder is configured but path entered does not exist in the file system. To fix the issue you just need to check and correct temporary path in php.ini file. If path is in-correct you need to correct folder path or if no folder path given then you need to set temporary path.

You can easily fix this by editing php.ini file. Most of the shared hosting provider now support custom php.ini per account. It means you can have you own php.ini and optimize php setting according to your need.

Apply following steps to complete this task.

1) Find out exact physical path of your account public_html folder. Create a text file and name it phpinfo.php. Add below lines in the file. Save file then upload file in the public_html folder of your server.

<?php phpinfo(); ?>

2) Run phpinfo.php file by pointing your browser to the file. http://www.yourdomain.com/phpinfo.php. Replace yourdomain.com with your actual domain  name.

3) Search for two entries _SERVER["SCRIPT_FILENAME"] and Loaded Configuration File. Note down value against these entries.

In my case value for above entries are

_SERVER["SCRIPT_FILENAME"]  -> /home/homefolder/public_html/phpinfo.php

Loaded Configuration File -> /etc/php/php.ini

4) If your hosting account support custom php.ini or you have server access then you can complete following steps otherwise you need to ask your hosting company to complete this for you.

If you have server command line access.

1. Create a temporary folder called “tmp” within your public_html folder from FTP. Now temporary folder path is /home/homefolder/public_html/tmp/
   
2. Login into the command prompt as server administrator.
3. Type below command and hit enter
4. $ sudo nano /etc/php/php.ini
5. It will open php.ini file in nano visual editor with root privileges. Enter root password if asked.
6. Find upload_tmp_dir and un-comment it if commented. “;” used for commenting purpose in php.ini. Simply remove this special character to un-comment line.
7. Change upload_tmp_dir value to /home/homefolder/public_html/tmp/. You line should appear similar to next line (8).
8. upload_tmp_dir = /home/homefolder/public_html/tmp/
9. Save php.ini file and restart apache.
10. Now again run phpinfo.php file in your browser. New value should appear in your php info setting.

If your host support custom php.ini

1. Create a temporary folder called “tmp” within your public_html folder from FTP. Now temporary folder path is /home/homefolder/public_html/tmp/
2. Create a text file called php.ini in your system and paste content in step (8) specified above.
3. Save file and upload to your public_html folder in your FTP.
4. Run phpinfo.php file in your browser. New value should appear in your php info setting.

Error should disappear now. However, in some cases you may still get same error. For those cases try removing trailing slash at the end of path. After the change path would be  /home/homefolder/public_html/tmp instead of /home/homefolder/public_html/tmp/
