HOWTO: Use RapidSVN for SVN

Posted by: Jennifer Zelazny | 3 Comments

If you are a web or application developer, there will come a time (hopefully) that you will need to use subversion for your projects. While I use the command line for this – there are some GUI applications that make it easy for people to manage their files using subversion. For this documentation, I have chosen to write about RapidSVN because it runs on both Mac and PC. ONE TIME PROCESS Download the RapidSVN you will use to check in and check out files at: http://www.rapidsvn.org/download/release/0.9.6/. For Mac users – download the .dmg gile. For PC users, download the .exe... Read More » Read more

Uncheck Checkbox Values

Posted by: Jennifer Zelazny | 0 Comments

I recently ran into a situation with a custom form where users had a number of checkboxes where the values were saved upon submit. When they went back through the form to make changes, if they unchecked something that was already checked and submitted the form again, the checkbox value would not change (not empty). The solution (thanks to Demitrious for finding this!) was simple. Read more

jQuery + CSS + XHTML = Jappler Menus v2

Posted by: Jennifer Zelazny | 6 Comments

Previously – I introduced a nice way to create drop down menus using HTML (lists), Javascript (drop down), and CSS (styling of menu). I put all of this together and called it: Jappler Menus. (See previous post about Jappler Menus). Since writing that post – I have found a better, faster, cleaner way to work with drop down menus. I had originally seen some nice menus: http://help-developer.com and decided with some changes – that would be a much nicer way to work with menus. For this – I give you Jappler Menus version 2. Here is an example of Jappler... Read More » Read more

Find and Replace With phpMyAdmin (or using SQL)

Posted by: Jennifer Zelazny | 2 Comments

Ever need to find and replace something in your WordPress database? (perhaps you changed domain names and have the old domain name or folder structure hard coded into some of your posts) You can easily update your database by using phpMyAdmin or by using the following code in any SQL interface: The first part of the command says “update the database table wp_posts” (where your content is stored). The later part of the command says “use the field “post_content” (where all your actual post content is stored” and then find “http://olddomain.com/blog” and replace it with “http://newdomain.com”.

Undelete Something With SVN

Posted by: Jennifer Zelazny | 5 Comments

Ever delete something with svn (svn del) and then realize you needed it again? You can get it back by using: svn copy -r HEAD filenameyoudeleted.extension filenameyoudeleted.extension svn copy is the command to get a working copy back -r is short for revision. I used HEAD which will give you the latest in repository. You can specify a revision number, revision right before you committed, etc (check out svn help copy) filename is what you deleted, then where it goes. I usually do something like this within the folder the file was located so you do not see any paths,... Read More » Read more

Switch Repositories (SVN)

Posted by: Jennifer Zelazny | 0 Comments

In order to take a look at WordPress 2.5 before it was released, I used subversion to check out the latest code available using the instructions given on the WordPress site. Once WordPress 2.5 was released, I wanted to keep my sites using 2.5 and not the bleeding edge releases (2.6) so I needed to easily switch repositories from http://svn.automattic.com/wordpress/trunk/ to http://svn.automattic.com/wordpress/branches/2.5/. I had never had to switch repositories, so it took some reading to figure it out. For future reference, the following command works when used in the directory you have the checked out files in: “svn switch http://newrepos.com... Read More » Read more

I feel that since owning my own business, I have had to work very hard to make the most of my time and have a few tips: Focus on 1-3 big tasks per day.
