Add Enctype To Wordpress Post And Page Forms

27th March 2010

Whilst creating a small plugin on a Wordpress site I decided not to use the media library as I just wanted to add some small stub images to the content. I created some boxes on the post page using add_meta_box() and added a file input box to them. The only thing is that the post form in Wordpress doesn't have the enctype="multipart/form-data" attribute and so it won't pass file to the $_FILES array in PHP.

It is not possible to add the enctype into the form declaration via Wordpress as there is no hook or action to do this. So the only alternative (rather than hack the source code) is to add the attribute using JavaScript, and as we have JQuery already loaded we can utilise that.

Wordpress Database Changes When Moving Site

27th March 2010

When moving a Wordpress install from one place to another there are a number of things you must be aware of. If you have created your templates properly you will have used calls to bloginfo('home') rather than using static links, but you will need to update these links to make your Wordpress install work properly.

Once the files are in place, the database connection details have been edited and the database created there are a number of things to alter in the database to make your Wordpress install work.

Wordpress Permalinks SEO Best Practice

12th March 2010

Setting up a permalinks structure in Wordpress one of the things I normally do right after installing a blog, before event getting started on the templates. However, I always seem to forget what to put in the box so I thought I would put this here to remind myself and to go over the best practices on your own site in terms of SEO.

To set the permalinks on your Wordpress install go into Settings > Permalinks and enter the following into the Custom Structure field.

parse_url Warning Bug In Wordpress 2.9.2

23rd February 2010

Whilst setting up a new Wordpress install for a site development I found an odd little issue that would only occur in certain circumstances. My current development platform consists of an Apache server on which I create a virtual host for every development site I need. However, rather than setting a DNS entry for each address I just listen to diferent ports. In this particular instance I used the port 59419.

When the install was complete I was presented with the following error at the top of every admin page.

Wordpress DoS Attack Script Solution

20th October 2009

There is a script knocking about on the internet at the moment that allows an attacker to run some code that will bring your Wordpress blog to it's knees. This will more than likely cause your host to get annoyed as well.

Wordpress 2.8.3 Admin Password Exploit And The Fix

11th August 2009

A small exploit has been found within the latest (currently 2.8.3) version of Wordpress that can cause any attacker to reset the admin password. The attacker won't be able to see what the password is, and the new password is emailed to you anyway, but it might cause some users to be locked out of their blogs if they can't get access to the email or their email is down. However, it is a real pain so I am writing this blog to allow other bloggers to fix their Wordpress installs.

Displaying Wordpress Authors

26th February 2009

Wordpress has a couple of rarely used functions that allow author information to be displayed for the current post and a list of all of the authors on the blog.

Adding a written by message to your posts is not difficult at all. Just use the the_author_posts_link() function inside the post loop.

Turn Off Wordpress Revisions

Wordpress has a nice little revisions feature that will allow you to revert to a previous version of a post if you don't like the current edit. However, the drawback of this feature is that it is not always needed and it fills the post table full of stuff you will never need. Fortunately, turning this feature off isn't too much of a pain. All you need to do is add the following line of code to your wp-config file, just below the DB_COLLATE line.

Wordpress Post Friendly Code With JavaScript Replace

12th February 2009

I recently talked about adding code to blogs and comments to Wordpress and making sure that certain characters are encoded properly. So to simplify things I thought I would create a little set of regular expressions that takes a sample of code and convert it into a Wordress friendly format. It consists of the following function, which takes the value of a text area called tochange and runs some regular expression replace functions on it.

Enabling Image Formatting In Your Wordpress Template

20th November 2008

One neat thing about Wordpress is the ability to add images to your posts in a quick and easy manner. You can also create thumbnails of larger images and link to them using a captioned image. The only problem is that when you have sorted out how your images look in your post in the admin section they just don't appear the same in your template once you have published it.
