15 helpful WordPress plugins for the savvy blogger
1) Google Syntax Highlighter for WordPress
Google Syntax Highligher for WordPress colorizes your code on-the-fly. It supports most programming/scripting languages such as C++, PHP, Perl, Ruby, and much more. The syntax is simple — just put your code inside <pre> tags and assign them the attributes name="code" and class="thelanguage".
2) Exec-PHP
Exec-PHP gives you the capability of running PHP code inside certain posts and pages. You can insert PHP code directly into your posts without having to modify your theme files. You can find a more detailed documentation of Exec-PHP on Bluesome.
3) Save My <pre>
If you use the visual editor, then you’ve probably experienced the frustration of trying to figure out why it messes up your <pre> tags. Code in between
the <pre> tag should preserve the indents, spaces, and linebreaks, but the default visual editor doesn’t uphold this rule.
4) Maintenance Mode
Maintenance Mode just notifies your readers that your blog is undergoing maintenance and is currently unavailable. The message won’t appear if you’re logged in as an administrator, so you can see what your updates look like during maintenance mode.
5) WP-DBManager
WP-DBManager gives you an administrative interface to manage, backup, and optimize your WordPress database. It has countless of options for making database management quite effortless. Installing this plugin gives you a new tab in the admin panel, called “Database“.
6) Deactivate Visual Editor
If you need to write intricate posts that have code snipplets and/or custom scripts, it’s highly advisable that you turn off the visual editor. But if you find value in the visual editor of WordPress, then you just may want to exclude certain posts and pages from using it. Installing the Deactivate Visual Editor WordPress plugin ensures that nothing gets accidentally screwed up when you edit a post that shouldn’t be edited using the visual editor. To deactivate the visual editor on a post or page, you’ll need to create a custom field called deactivate_visual_editor and set the value to true.
7) Search and Replace
Ever wanted to change a user’s name, email, website URL on old posts? How about correcting references to an old post that no longer exists or whose name has been editted? Search and Replace allows you to do all of this inside of WordPress, through an intuitive admin interface.
