How to Protect your WordPress Admin Area

This  is important to restrict the access to your WordPress admin area only to people that actually need access to it. If your site does not support registration or front-end content creation, your visitors should not be able to access your /wp-admin/ folder or the wp-login.php file. The best you can do is to get your home IP address (you can use a site like whatismyip.com for that) and add these lines to the .htaccess file in your WordPress admin folder replacing xx.xxx.xxx.xxx with your IP address:

12345<Files wp-login.php>order deny,allowDeny from allAllow from xx.xxx.xxx.xxx</Files>

In case you want to allow access to multiple computers (like your office, home PC, laptop, etc.), simply add another Allow from xx.xxx.xxx.xxx statement on a new line.

And do not forget- DO not never use  USER as login !

How to Create a Customized Date Button for WordPress

When making your blog stand out, one thing that bloggers often ignore is the date button. Something as simple as a customized date button can really make a difference in your blog’s design. Therefore in this article we will show you how you can create a customized date button for WordPress.

We will start out from the image shown in the left, and will make it look like the one in the right.

You can use the image that we are using above if you so desire for your use, or create your own one.

First thing you need to do is open your style.css file and add something like below:

.datebg{ background: url(images/datebg.gif) no-repeat; height: 173px; width: 173px; } .day{ } .month{ }

Now you may style it however you like, and you can also change the name of the class. Then you would need to open your index.php and single.php. And add the following code where your template fits.

<div class="datebg"> <div class="month"><?php the_time(’M’) ?></div> <div class="day"><?php the_time(’d’) ?></div> </div>

Make sure you change the styling to fit your needs. Now you should have a customized date image. You can also refer to WordPress Codex for more information.

WP-Add Images in WordPress Sidebar

Add Images in WordPress Sidebar

First, you need to upload the image to your WordPress site using the media uploader and copy its URL.

Next, go to Appearance » Widgets page and add a text widget to your sidebar. Inside the text widget you will need to add the HTML in the following format.

<img src="Paste image URL here" alt="Alternate text" />

You can now save your widget settings and preview your website.

For more details see our guide on how to add an image in WordPress sidebar widget.

1

'widget_text'

'do_shortcode'

);

WP- Add Custom Default Gravatar Image

WordPress uses Gravatar to display user profile photos in WordPress. If a user does not have a gravatar, then WordPress uses a default image which is called ‘Mystery Person’.

This default gravatar image will appear many times in your WordPress comments area simply because a lot of users do not have a gravatar image associated with their email address.

You can easily replace this default gravatar with your own custom default gravatar image.

First you will need to upload the image you want to use as your default gravatar image to your WordPress media library.

Next, you need to copy the image file URL.

Now you need to add the following code to your theme’s functions.php file or a site-specific plugin.

123456

add_filter(

'avatar_defaults'

,

'wpb_new_gravatar'

);

function

wpb_new_gravatar (

$avatar_defaults

) {

$myavatar

=

'http://example.com/wp-content/uploads/2017/01/wpb-default-gravatar.png'

;

$avatar_defaults

[

$myavatar

] =

"Default Gravatar"

;

return

$avatar_defaults

;

}

Don’t forget to replace $myavatar value with the URL of the custom gravatar image you uploaded earlier.

You can now visit Settings » Discussion page, and you will notice your custom default avatar added to default avatar choices.

For detailed instructions check out our tutorial on how to add change the default gravatar in WordPress.

Display Excerpt (Post Summary) on Home and Archive Pages

You may have noticed that all popular blogs show article summary instead of full article on their home and archive pages. It makes those pages load faster, increases page views, and avoids duplicate content across your website.

For more on this topic, see our article on excerpt (summary) vs full posts in WordPress archive pages.

Many premium and free WordPress themes already use excerpts on home and archive pages. However, if your theme doesn’t display excerpts, then see our guide on how to display post excerpts in WordPress themes.

SQL- Tips to resolve “Table error: Object O_ID… page P_ID was not encountered.” Error

sql-server-recovery-blog1:

The records in Microsoft SQL Server database can be placed and located in the form of a B-tree. These records are divided into various pages (child pages), each having a unique index page, which is one level up in hierarchy from the child page. Corruption in the hierarchical tree structure (metadata structure corruption) primarily results in loosing the reference of the child page from the Index page. In such situations, the data stored in the database becomes inaccessible. For accessing the data stored in the database, an ideal way is to restore it from an updated database backup. But if in case of absence of an valid database backup, you will need to use advanced MS SQL Database Recovery application to repair your database. Consider a practical scenario, where you receive the below error message when you attempt to access the records stored in table: “Table error: Object ID O_ID, index ID I_ID. Parent node for page P_ID was not encountered.” The above error message makes the data stored in table inaccessible. Moreover, the error message repeatedly repeats every time you attempt to access the records stored in the table. Cause: The root cause for the occurrence of the above error message is SQL database corruption due to metadata structure damage. Note: SQL database can be corrupted either due to logical or physical factors. Resolution: To resolve the above error message and to access the table records, you will need to follow the below measures:

To solve all the corruption issues caused due to physical damage, swap the corrupt system component with a new component.

To solve  all the corruption issues caused due to logical damage, run DBCC CHECKDB command with correct repair clause.

The first measure is competent enough to resolve all the physical damage issues. The second measure, however, fails to resolve all logical corruption problems. For such situations, the database table can be repaired by using advanced MS SQL Database Repair software. These SQL Server Recovery utilities employ effective scanning methods to completely repair the corrupt table after all logical database corruption scenarios.

Java- What is the difference between execute, executeQuery, executeUpdate?

What is the difference between execute, executeQuery, executeUpdate?

Statement execute(String query) is used to execute any SQL query and it returns TRUE if the result is an ResultSet such as running Select queries. The output is FALSE when there is no ResultSet object such as running Insert or Update queries. We can use getResultSet() to get the ResultSet and getUpdateCount() method to retrieve the update count.

Statement executeQuery(String query) is used to execute Select queries and returns the ResultSet. ResultSet returned is never null even if there are no records matching the query. When executing select queries we should use executeQuery method so that if someone tries to execute insert/update statement it will throw java.sql.SQLException with message “executeQuery method can not be used for update”.

Statement executeUpdate(String query) is used to execute Insert/Update/Delete (DML) statements or DDL statements that returns nothing. The output is int and equals to the row count for SQL Data Manipulation Language (DML) statements. For DDL statements, the output is 0.

You should use execute() method only when you are not sure about the type of statement else use executeQuery or executeUpdate method.
