A better way to get item url in WordPress

Tagged Under :

When linking to posts or images from your posts, there is a more versatile means of doing so. Imagine that you change themes or move to another domain. You need to go through entire posts to search and replace every link.

Maybe you will think linking the posts or images like below example:
<a href="../contact/" >Contact Us</a>
But it was bad way.

This is worse as well:
<a href="" >Contact Us</a>

MySQL ordering by specific field values

Tagged Under : ,

There may be times when a specific order is required in a SQL query which cannot be done using either ASC or DESC or using a special sort field. MySQL has a ORDER BY FIELD function which can be used to do this.

Example Data
The example data in this post uses as below. This is a somewhat simple table but it can be used to illustrate the point in this post quite well.
CREATE TABLE fruits (`id` int, `name` varchar(50));
INSERT INTO fruits (`id`, `name`)
VALUES (1, 'Apple'),
       (2, 'Durian'),
       (3, 'Banana'),

WordPress easy way to display the number of search results

Tagged Under :

In prepping the new site design for my client, I need to show the total number of search results on my search page.

From the wordpress Forum I found 1 of the solution. Like the below example code.
$mySearch =& new WP_Query("s=$s & showposts=-1");
$num = $mySearch->post_count;
echo $num. "results";
But unfortunately, sometimes it still gave me the wrong count.

December 06 2013 MVC Razor if else statement display output

Tagged Under :
Not all content container blocks start with a tag element tag, though, and there are scenarios where the Razor parser cannot implicitly detect a content block.

Razor addresses this by enabling you to explicitly indicate the beginning of a line of content by using the @: character sequence within a code block. The @: sequence indicates that the line of content that follows should be treated as a content block:
@if (someCondition) {
  @: Some content to display...

For more practical example, the below snippet demonstrates how we could output a "Not Stock" message to our product if numbers of product is zero.
@if (model.unit_stock == 0) {
  @: Not Stock

Because I am not wrapping the "Not Stock" message in an HTML tag element, Razor can’t implicitly determine that the content within the @if block is the start of a content block. We are using the @: character sequence to explicitly indicate that this line within our code block should be treated as content.

PHPUnit Selenium get url parameter

Tagged Under : ,

Just now I wrote PHPUnit test case to try get the url parameter with Selenium. In PHP use $_GET function, you can get all the URL parameter. But it doesn’t work in PHPUnit with Selenium.

To solve it was simple, used “$this->getLocation()” function to get current url and then used PHP “parse_url()” and “parse_str()” to get the parameter.
