I have many posts in wordpress. In that post I have links like dev.dev.example.com now I want it to replace with dev.example.com.
I am using following query
UPDATE `dbname`.`wp_posts` SET `post_content`= replace(cast(post_content as varchar(max)), '%dev.dev.example.com%', '') WHERE CONVERT(`post_content` USING utf8) LIKE '%dev.example.com%'
I think it is better to follow wordpress' official guide when moving a wordpress website. http://codex.wordpress.org/Moving_WordPress
Alternatively, as an easy way in your case if you have already done all other steps but stuck in this issue, you can export database to sql file, open in text editor like notepad, use find-and-replace to replace all x.com to y.tom and then import the database. But remember that if domain length is different, you will have some settings lost. It is because wordpress keeps serialized data where length is stored.
Using your way to do via query is not a robust way because some other tables may still have old domain name.

the thing is, In my WordPress website i have posted some links to some post. and the domain name of the links have been changed and they are so much in an amount in total of 549 posts.the link is like this yourdomain.com/free-access/ and they are in a button. so any suggestions how can i change the domain name.
thanks
The best way to change the domain names in posts is to export and download the database backup. Search and replace the domain name occurrences and save the sql file. Then import the sql file.
You can do a global search and replace with a plugin. There are others but I suggest Better Search and Replace. It's in the WordPress Repository and is free.
Before you make a change like this you should run a full backup, just in case anything goes wrong.
The plugin in question will let you do a dry run, that is you enter your search text and replace text, select the tables you want to search in and then check the box to Run as Dry Run. This will show you where your changes would be made without actually making them, so you're sure you've entered the right search and replace terms.
You can also make changes like this directly on the database tables using SQL but I strongly recommend against it. This tool is much safer.
I have created a custom page in Wordpress which presents different data based on the query string. So my query string right now looks something like
http://example.com/extcat/?uid=15&src=blog
Now this is not getting picked either by Google's spidering software or by tracking software properly. They are all tracking it as one single page
http://example.com/extcat
without the uid.
What I want is to rewrite the above query in a format like one of these
http://example.com/extcat/uid/15/src/blog
http://example.com/extcat/15/blog
http://example.com/extcat/15/?src=blog
http://example.com/extcat/15/
I don't care which format I use.
I tried using .htaccess and the WordPress api both. Nothing seems to work.
Here is an in-depth article on how to accomplish what you are doing. Basically, you'll need to register your custom query variables so WP can do it's magic using add_rewrite_rule(). It's a long article, but will provide a better answer then I can write. Plus, you'll learn a whole lot!

In an attempt to redesign a website, I put this page together by hand. However, there are currently over 100 more shows already that need to be added, and three new shows get added every year.
In the old system, a text document was used as a makeshift 'database'; it stored data about each show, with shows separated by '#' and data fields separated with ']'. Here's an excerpt:
#The Whorl of the Leaves]WhorlOfTheLeaves]3]F]167
#Aladdin]Aladdin]8]N]0
#A Christmas Carol]XmasCarol84-]7]N]0
#The Feral Child]FeralChild]7]N]118
#Camelot]Camelot]11]N]169
A PHP script was then used to extract the information about each show and make the page seen here.
I'm sure a script could be used to put together a page such as the one shown above, but it seems like there should be a better system than a text document to store the information.
My question is: if the text document 'database' is working, should I bother changing it? Is there a better way to organize the information about each show?
SQLite would be prefect for you. It's a tiny database that requires no configuration or setup - yet comes built into most PHP installs.
Just use PDO and your good.
$db = new PDO('sqlite:/path/to/here/mydb.sq3');
$db->query('SELECT * FROM shows');
Yep, there are a ton of "better" ways of doing this. But if you're happy with it and it works, why change it?
You could save yourself a lot of trouble by using a content management system such as drupal.
For example, say if a user wanted to 'add a place' to my database, how could I create a page almost instantly with that place's name in the domain e.g www.mydomain.com/placename?
I understand it might be a complex solution so if it is too complex to explain can you please push me into the right direction of what I should be researching.
Create functionality to create "pretty urls" in php. Read more about that here: http://www.roscripts.com/Pretty_URLs_-_a_guide_to_URL_rewriting-168.html
Create parsing functionality for the urls, so that it recognizes "/placename" as the page "placename"
Create a database structure for pages with the page id, title, content and the url slug, etc.
Create functionality to fetch the right page from the database according to the matching url slug.
Create functionality to render the retrieved informaton
If I understood you right that's one approach to what you want to do.
I'm assuming you're using Apache. If so, create a rule using mod_rewrite that forwards requests for /place/placename to /place.php?name=placename. Then write the place.php script, which will pull the user page from the database and display it in the appropriate fashion.
That's one way to do it - there are others.
First of all try to understand mod rewrite.
You could "mask: a GET url into a much nicer format.
Start here : http://www.elated.com/articles/mod-rewrite-tutorial-for-absolute-beginners/
Then google on and get yourself familiar with all the possibilities.
After that make sure the GET variable is unique in your database, to be absolutely sure use a unique ID.
Example :
domain.com/PLACEID/PLACENAME/
mod_rewrite could then translate this to your php script into :
domain.com/place.php?VAR=PLACEID&VAR2=PLACENAME
Search the data from the user/place through the PLACEID .
Good luck
I am working on building a small php/mysql script that will act something like a wordpress blog but will just be a small site for my eyes only to store PHP code snippets. So I will have categories and then pages with sample code that I write with a javascript syntax highlighter. Instead of storing my php code snippets in the file I am wanting to save them to mysql DB. So what is the best way to save PHP into mysql and to get it out of mysql to show on the page?
My end result will be something like this
alt text http://img2.pict.com/c1/c4/69/2516419/0/800/screenshot2b193.png
Update:
I just wasn't sure if I needed to do something special to the code before sending it to mysql since it has all different kinds of characters in it
Just store in a text field, as is. Not much more beyond that.
If you're not using some kind of database abstraction layer, just call mysql_real_escape_string on the text.
Do you want to be able to search the php code? If so, I recommend using the MyISAM table type as it supports full text indexes (InnoDB does not). Your choices for column type when it comes to a fulltext index are char, varchar and text. I would go with text as your code snippets might get too long for the other types.
Another point worth mentioning, is make sure you properly escape all php code (or any value for that matter) before you insert it. The best way to do this is by using parameterized queries.
Unless I'm missing part of the problem, you should be safe storing it as a TEXT field in a MySQL database. Just make absolutely sure you sanitize the code snippets, as PHP code in particular is quite likely to contain the characters that will escape out of an SQL string. (If you're already using an SQL framework, odds are the framework is doing this for you.)
Store as text (varchar) in the database.
Use cascading style sheet (css) to format code.

Try this:
mysql select ...
eval('?>' . $row['phpcode'] . '<?php ');
