Unless you’re a complete masochist, you’re doing to want to split this into a more manageable data set, otherwise you’re gonna eat all the memory on your server. But this means that you can no longer use the DataSet.Tables[0].Rows.Count property to figure out how many rows you have. You can write a second stored procedure that’ll count the rows. But who wants to clog up their database with tons of stored procedures for no reason? Let’s consolidate it into one.

So what does this look like?

First: the stored procedure.

We’ll use output parameters to pass the row count back to our code


create procedure [dbo].[Search]
@searchText varchar(512), @recordsToReturn INT, @pageNumber INT, @numberofrows INT OUTPUT
AS

Now the C# (this’ll work in VB too, but feel free to convert it yourself)


SqlConnection conn = new SqlConnection();
conn.ConnectionString = ".....your connection string here.....";
conn.Open();

da.Dispose();
conn.Close();


Best of luck! As always, leave a message in the comments if you have questions

important note! make sure that you don’t select the primary key of the table. instead, select 0, and the auto_increment function will automatically figure out the correct primary key

As always, if you have questions, post em in the comments!

Today, while working on a pretty simple plugin, I wanted to add this functionality, and I didn’t want to waste a bunch of time. I was given a link to this great script: http://www.warkensoft.com/2009/12/paginated-navigation-bar/

It took me about a minute to implement the functionality. I then spent another 5 minutes doing CSS and that was it. Done. I’m not usually one for link sharing, but this made my life much easier. Hopefully it can make yours easier too.

The solution is pure PHP, no javascript required. Some day, I may try to expand upon this to include javascripty goodness, because that’s pretty much the only thing that could make it better

you get a message something like:

-bash: mysqldump: command not found


so how do you fix this? well, copy and paste the following into your terminal window and press enter:

echo export PATH="/usr/local/bin:/usr/local/sbin:/usr/local/mysql/bin:$PATH" >> ~/.profile

source ~/.profile


whoa, whoa, you say. what is this doing? It makes it so that when you type any command into the terminal, it does a check of these folders before giving you the “command not found” error.

If you want to undo it, you can always edit your .profile, or just delete it.

1. go to google maps, type the address, and click search
2. once you’ve found it, go to your address bar and clear what’s in it
3. paste: javascript:void(prompt('',gApplication.getMap().getCenter())); into the address bar
4. use the coordinates for whatever you wish!

if you’re using the new version of VirtualHostX, make sure that you select Directory from the dropdown, then use:


Options FollowSymLinks
AllowOverride All AuthConfig



So I wrote a class that you can extend with any model class of your own, and it will automatically have create, read, update, and delete functionality with no more work required. It also uses all of the WordPress security features to properly escape everything and prevent injection. Although, if you can crack it I’d love to hear from you!

This is how it works:

1. Create a new class (ex. person)
2. Give that class instance variables (ID, FirstName, LastName, Address, PhoneNumber, PostalCode, HairColour…)
3. Make sure that you add accessor methods (getters and setters) for the ID (although it’s good practice to have them for all instance variables). Depending on your project, it may be a good idea to run stripslashes() on your string get functions so that they don’t show up with escaping. You may want to run WordPress’ attribute_escape() on setters, however, again, depending on your set up this may be unnecessary.
4. Write your SQL code to create a table named (wordPress prefix)(plugin prefix)person (ex. wp_wec_person)
5. Make sure you call your primary Key personID **This is very important, without this, the system breaks down**
6. If you wish to store variables in this class, you can modify them to be private, and they won’t be written to the database

In your class, extend the class name, so for example:

class person extends wec_db {

var $ID;

var $FirstName;

function __construct($id = null, $autoload = true){

}

Setup Note: to keep your plugin from stepping on the toes of others, make sure you change the prefix at the top of the class. Also, changing the name of the class to (plugin prefix)db (example:wec_db) will make sure that it doesn’t interfere with anyone else’s if they’re using this class!

Usage:

Create / Add

$person = new person();

$person->setFirstName(‘Joe’);

$person->setLastName(‘Blow’);

$person->add();

Read

$person = new person($personID);

Update

$person = new person($personID);

–or–

$person = new person($personID, false);

$person->setFirstName(‘Jane’);

$person->update();

Delete

$person = new person($personID, false);

$person->delete();

Post any questions in the comments! I’d love to hear from you!

Why, yes it would. Try:

Event.observe(window, 'load', function(){
     try {
          $('eventName').focus();
     } 

     catch (e) {}
});

after your </form> tag. This requires the prototype javascript library
