Disabling smart quotes in WordPress
I remember the times when I started blogging about websites codes and scripts. Back then, I had several difficulties in using WordPress 2.3 like suddenly changing <br/> tags into paragraph tags <p> and </p> that does not contain anything in between as well as suddenly changing <div> tags into <p> tags.
It ruins the presentation of my blog and I need to be really careful. I did drastic stuff like making a back-up of HTML hand coded copy of my blog posts and not switching to WYSIWYG mode at all times.
Fortunately, WordPress 2.7 and later versions no longer do those.
Another difficulty, aside from presentation, is that WordPress tends to change the single and double quotes in the codes into curly ones in my tutorials. This still happens up to WordPress 3.5, the latest version at the time this post was updated.
I find it rather silly because when I copy and paste codes from my own tutorials, they no longer work. When I examined the source code, the quotes were replaced by something like ‘ and ’, which produce curly quotes like (‘) and (’); they look elegant but they simply don't work in website codes and scripts.
You type straight quotes such as (') or (") and WordPress replace them with curly quotes (‘) or (”). Fortunately, there is a very simple solution.
All you need to do is to disable the smart quote feature by inserting the code below in the functions.php file of the WordPress theme in use.
If you are not sure where or how to insert this code in functions.php. click here.
After this, you can test it by writing a blog entry and type a single quote and a double quote somewhere in the post. Save the post (it doesn't matter whether you publish it right away or save it as draft). Then, preview the post and see if the quotes are straight or curly. If they are straight, check the source code. If you did it correctly, the quotes should be seen as (') and (") even in source codes.
This method should work for versions 2.3, 2.7, and 3.5, and any version of WordPress in between them; it is also likely to work in versions lower but close to 2.3 and higher but near 3.5
