This was something new to us, and after doing some research we discovered that WordPress only allows users to upload certain types of files, and any files that are not part of that list cannot be uploaded through the admin. Here’s the list of accepted WordPress files types.

It turns out that the list of accepted file types is found in wp-includes/functions.php. Since we don’t want to modify WordPress core files, we need a solution like a plugin in order to get around this limitation.

Chris Meller has a solution that involves adding some code to your functions.php file in your theme directory. He also explains how to remove file types from the list of allowed files types.

For more info on how to do this, see this post on his blog: Modifying Allowed Upload Types in Wordpress.

Thanks to Mark Kaplun for helping us find this solution.

Uploading files on Write > Page in WordPress admin:

I explained that you could use a plugin called Filosofo Old-Style Upload Plugin to change where files are saved on your server.

Well, Ryan Hellyer pointed something out that I can’t believe I never noticed: you can change where and how files are saved in WordPress!

Many of you are probably saying “Duh!” But I really never noticed this, so please humor me.

To change where your uploaded files are saved on the server:

1. Go to Option > Miscellaneous in your WordPress admin
2. Under Store uploads in this folder, enter the file structure that you want. For example, wp-content/themes/themename/images.
3. Where it says “Organize my uploads into month- and year-based folders”, you can unselect the check box so that all images will be saved in the one folder you specified in step 2.
4. Click on Update Options to save your new setup.

I can’t really see any advantage to saving the images in folders according to year and date, so I would make this change right from the beginning of any WordPress blog.

[By the way, did you notice my snazzy new screenshots? Until now I've always hesitated to add screenshots because I was using a free but not-very-efficient screen capture tool. But now I'm using the free and amazing SnagIt from TechSmith. If you haven't heard, TechSmith is offering older versions of their SnagIt and Camtasia Studio software for free! If you want to upload to their most recent version, it's only half price once you've downloaded these older versions!

They are both so great, that you really should download them, even if you don't think you'll have any use for them right now. Go to Quick Online Tips for information on how to download and get the license keys.]

Search Everything from Dan Cameron solves that problem. Install and activate the plugin, and then go to Options > Search Everything to select what exactly you want to be searched. Here are the options:

• Pages
• Comments
• Only approved comments
• Drafts
• Attachments
• Custom fields (metadata)

I’m not sure why people would want users to see results in drafts or custom fields, but maybe there is a use for that that I’m not aware of.

Search Everything Plugin>> 

If you are building a site for clients based on WordPress, you want to make it as easy for them as possible to enter information without having to consider coding and other issues.

This plugin is great for those types of sites, as well as for anyone with a WordPress site who wants to have one less thing to think about. When a file is selected for uploading, this plugin changes the filename according to the following three rules:

• only lowercase;

• convert spaces in underscores ( _ )
