JQuery 1.3 domination through deprecation

By Josh Highland in javascript, software, web 2.0

jquery 1.3

On a project I maintain, we recently rolled up to JQuery 1.3.1 from JQuery 1.2.6. Upon doing so, several things instantly broke.

I started seeing errors on lines like this:

if($('input[@name=username]').val() != "")

I decided to check the JQuery 1.3 relase notes to see what had changed.

The first bullet point answered my problem:

The ‘@’ in [@attr] has been removed. Deprecated since 1.2 this old syntax no longer works. Simply remove the @ to upgrade.

As it turns out, the @ style selector was depricated and wasn’t suggested for use when JQuery 1.2 was released, but it was still supported. At 1.3 the @ style selector was removed all together, and as a result broke our code!

Following the upgrade instruction I removed the @ symbol from the selectors, and the code started running again.

The result:

if($('input[name=username]').val() != "")

A simple and effective upgrade, and a reason to closely pay attention to release notes

Manually reset your WordPress password

It doesn’t matter what application your working with, losing your password is always a pain in the ass. Luckly if you are working with wordpress (man, I blog a lot about wordpress these days), on your server and you have access to the MySql database, resetting your password manually is a snap.

  • Login to your PhpMyAdmin
  • Select your WordPress database and click on the “SQL” button to open the SQL query window.

wordpress-phpmyadmin

  • Paste the following code in the window textarea. (Don’t forget to modify the password and username before executing it)

UPDATE ‘wp_users’ SET ‘user_pass’ = MD5(‘PASSWORD’) WHERE ‘user_login’ =’admin’;

That’s it! Your password has been reset, and you should be able to login to your wordpress admin area once again.


			



	

		
Solution for: MySQL server has gone away at mysqlhotcopy line 528

Recently I was backing up a large MySql database (several hundred megabytes), using the awesome MySqlHotCopy script, when I started getting the following error:


DBD::mysql::db do failed: MySQL server has gone away at mysqlhotcopy line 528.


I have no clue what that error means. mysqlhotcopyworked great on all of my other smaller databases. I did a little searching on my old friend google, and after sniffing around a bit, I came up with a resolution to the problem… the script was timing out, so I just had to increase the allowed time in the /etc/my.cnf file.


Here are the steps I took


pico /etc/my.cnf


add these lines to the file:

interactive_timeout = 3600

wait_timeout = 3600


save file


/etc/init.d/mysqld restart


I ran mysqlhotcopy again, and everything worked and the backup was made.

			



	

		
Modifying MimboPro to Add Paged Navigation To Category Pages

Recently I have been doing a lot of work with WordPress. I love WordPress. one of the things I like most about WordPress is the plugins and themes.


I recently bought a copy of the MimboPro theme. Mimbo is clean and very professional. More of a CMS theme then a blogging theme, prefect for what I want to use it for.


As I dug into MimboPro and WordPress, I realized something strange, the MimboPro theme doesn’t support paging in a category view. What this means is EVERY SINGLE post you make is shown on one page. If you have a very active site, like the one I’m working on, this quickly gets out of hand. Look at this image and you will see what I mean (click for full version).




One of the reasons I like MimboPro was the support that the authors of the theme offer. I headed over to their message forums and found other people like me asking for the Additon of Paged Navigation To Category Pages. The original post was 8 months ago, and no one had resolved anything. I made a post to the MimboPro authors only to be told that there is going to be a new theme that will handle this and it will be available at a deep discount to MimboPro owner. This upset me a bit, so taking matters into my own hand, I fixed what Mimbo wont, and I am handing out my own patch to solve this issue. Below are the instructions to hack your own files, or you can just download my zip file with the pre-hacked files.


Pre-Hacked Files:

DIY INSTRUCTIONS (click images for full sizes):


    

  1. Save a copy of your current categories.php and styles.css files inside of the MimboPro theme directory to a safe location
    2. 

  2. Open up categories.php inside of the MimboPro theme directory, and find line 17
    

    3. 

  3. Comment line 17 with a double back slash (//)
    

    4. 

  4. Go to line 87 of category.php and add the following code
    

    5. 

  5. Save and close category.php
    6. 

  6. Open up style.css inside of the MimboPro theme directory
    7. 

  7. Add the following CSS code to the bottom of the file (should be close to line 852)
    

    8. 

  8. Save styles.css
    9. 

  9. Upload categories.php and styles.css to the MimboPro theme directory on your server
    10. 

  10. Everything should be working. Here is what my wordpress running MimboPro looks like
    

    11. 



That’s it! MimboPro will now have paging in all of the categories. The next and previous links will only show up when you have enough posts. The WordPress default is 10 posts. You can edit the number of posts by going to change the number of posts to show on a category page, go into to the admin and under “setting” > “reading” you will find the option, as highlighted here.




If you had any problem reading the code in the image files, download the zip files with the pre-hacked files in them.
