$meta_l = get_post_meta($post->ID, "jobs_location", true);

echo '<input type="hidden" name="jobs-nonce" id="jobs-nonce" value="' . wp_create_nonce( 'jobs-nonce' ) . '" />';

wordpress WP_Query vs query_posts vs get_posts
	


	

		
WordPress tutorial, wordpress WP_Query vs query_posts vs get_posts. There are three ways for fetching data(posts) from wordpress. query_posts  more often than others. But I prefer to use WP_Query(). WP_Query is object base more secure then others.

query_posts() is overly simplistic and problematic way to to modify main query of page by replacing it with new instance of the query. It is inefficient (re-runs SQL queries) and will outright fail in some circumstances (especially often when dealing with pagination). Any modern WP code should use more reliable methods, like making use ofpre_get_posts hook, for this purpose. TL;DR don’t use query_posts() ever;


get_posts() is very similar in usage and accepts same arguments (with some nuances, like different defaults), but returns array of posts, doesn’t modify global variables and is safe to use anywhere;


WP_Query class powers both behind the scenes, but you can also create and work with own object of it. Bit more complex, less restrictions, also safe to use anywhere.


The basic difference is that query_posts() is really only for modifying the current Loop. Once you’re done it’s necessary to reset the loop and send it on its merry way. This method is also a little easier to understand, simply because your “query” is basically a URL string that you pass to the function, like so:


query_posts(‘meta_key=color&meta_value=blue’);

On the other hand, wp_query is more of a general purpose tool, and is more like directly writing MySQL queries than query_posts() is. You can also use it anywhere (not just in the Loop) and it doesn’t interfere with any currently running post queries.

code syntax highlighter through wordpress plugins
	


	

		
When ever we write some code in post. That code need to visible very easily. Here are some code syntax highlighter through wordpress plugins which will be useful for developers and coders. There are some useful wordpress plugins for highlighting the code in wordpress post.

While WordPress.com doesn’t allow you to use potentially dangerous code on your blog, there is a way to post source code for viewing. We have created a shortcode you can wrap around source code that preserves its formatting and even provides syntax highlighting for certain languages, like so:


To accomplish the above, just wrap your code in these tags:


 your code here
 


The language parameter controls how the code is syntax highlighted. The following languages are supported:


    

  • actionscript3
    • 

  • bash
    • 

  • coldfusion
    • 

  • cpp
    • 

  • csharp
    • 

  • css
    • 

  • delphi
    • 

  • erlang
    • 

  • fsharp
    • 

  • diff
    • 

  • groovy
    • 

  • javascript
    • 

  • java
    • 

  • javafx
    • 

  • matlab (keywords only)
    • 

  • objc
    • 

  • perl
    • 

  • php
    • 

  • text
    • 

  • powershell
    • 

  • python
    • 

  • ruby
    • 

  • scala
    • 

  • sql
    • 

  • vb
    • 

  • xml
    • 



If the language parameter is not set, it will default to “text” (no syntax highlighting).


Code in between the source code tags will automatically be encoded for display, you don’t need to worry about HTML entities or anything.


There are some free plugins also helpful for syntax highlighting.  I specially like the SyntaxHighlighter Evolved wordpress plugin. SyntaxHighlighter Evolved allows you to easily post syntax-highlighted code to your site without loosing it’s formatting or making any manual changes.


You can download this plugin form here:


SyntaxHighlighter Evolved


There is another plugin for syntax highlighting which also really nice.


WP-Syntax provides clean syntax highlighting using GeSHi — supporting a wide range of popular languages. It supports highlighting with or without line numbers and maintains formatting while copying snippets of code from the browser.


It avoids conflicts with other 3rd party plugins by running an early pre-filter and a late post-filter that substitutes and pulls the code snippets out first and then pushes them back in with highlighting at the end. The result is source code formatted and highlighted the way you intended.


You can download the this from here:
