As you know whenever an user login to WordPress system, who-ever it may be admin or just a subscriber, WordPress automatically shows an admin bar at top of the screen. If the user is administrator then this admin bar provides some useful functionality such as links to navigate to various admin panels of websites, moderating comments, shows available updates etc. The options may be vary depending upon the plugins you have installed.
You might know that this admin bar can be hidden form Profile > Toolbar > Uncheck “Show Toolbar when viewing site”. This is something depends on user’s will. If they like that admin bar they will not hide it.
But it may happen that, you want to hide admin bar for all users maybe due to it interferes with your design. Then you can achieve this using simple WordPress hook:
add_filter('show_admin_bar', '__return_false');
Now the admin bar will be hidden from all user. That’s all. Thank you WordPress hooks!
As a web developer you might be using AJAX for various purpose. AJAX provides a great capability of working with data through asynchronous calls.

Are you getting annoyed by Facebook chat messages? In past days, if somebody is constantly bombarding you with annoying chat messages then there was a solution to avoid those conversations. Just don’t reply to those messages and then after sometime reply like you have not seen any of those messages. But now Facebook updated their chat feature. They have implemented Read Receipt feature on Facebook Chat. Now-a-days when somebody sends you a chat message, he or she will get a receipt that you have read his/her message or not. Hence old excuses will not work now. Now as sender knows, you have read his/her message or not, you cannot neglect them. Hence there is no option other than replying those annoying chat messages or turn off Facebook chat whenever such things happens. According to me, second option is not quite useful at many times.
Facebook Read Receipt Screenshot
Facebook do offers a lot of privacy settings, but they do not offer any setting to turn off read receipt feature of Facebook chat. Hence to get such functionality you have to relay on some third party apps to turn it off. Luckily there is a browser extension for Google Chrome and Mozilla Firefox. This extension will allow you to read all those messages and also allows you to stay undetected. Just navigate to this site and simply click on that big green “Get Chat Undetected” button.
If you are using Google Chrome then a installation file will be downloaded to your PC. Once download is completed, you just have to close Google Chrome if it is running and then run that installation file and Chat Undetected will get installed on your Google Chrome. If you are using Mozilla Firefox then you will receive an add-on notice on your screen as soon as you click on that button, confirming the installation of Chat Undetected. Click on “Install Now” and Chat Undetected will get installed your Mozilla Firefox in few seconds.
Once you installed add-on on Mozilla Firefox or Google Chrome, the add-on will block your browser from sending those “Seen” receipts to Facebook. That simply means, now onward the sender will not get acknowledgements that you have read his or her messages. So now, if he/she starts fight with you on topic “You are not replying me on Facebook chat” then you can simply ask “Did you received acknowledgement?”. As acknowledgement is not sent to your friend, Of-course he/she will say “No” and then you can simply behave like you don’t know anything. That’s simple. Now you can handle all those annoying chat messages on Facebook.

Then you click on that word, Firefox gives you some suggestions, then you select properly spelled word. That’s how you use spell check.

Enabling spell check for all input boxes will irritate you initially. But once you learn how to use that option, you will like it everywhere.
Many sites do use WordPress for blogging but they do not use it as back-end for whole site. (Your site or app may be one of them.) There may be a scenario in which you have to display recent posts from WordPress blog, on a page which is outside of WordPress. No problem. You might know that WordPress is quite flexible, hence you can handle such scenario with a small code. There are two ways to achieve this. You can either take advantage of WordPress loop itself or if you don’t want to deal with WordPress loop then you can use other way also.
If you don’t want WordPress loop
So you don’to want to take advantage of WordPress loop? Then you can use wp_get_recent_posts(). According to WordPress codex:
wp_get_recent_posts() will return a list of posts. Different from get_posts which returns an array of post objects.
How to use it?
Just copy paste following code in page where you want to list the Recent Posts
include('wp-load.php');
// Get the last 10 posts
$recent_posts = wp_get_recent_posts(array(
'numberposts' => 10,
'post_type' => 'post',
'post_status' => 'publish'
));
// Display them as list
echo '<ul>';
foreach($recent_posts as $post) {
echo '<li><a href="', get_permalink($post['ID']), '">', $post['post_title'], '</a></li>';
}
echo '</ul>';
You can simply change numberposts parameters value to change the number of posts you want to retrieve.
