Mysql: Waiting for table metadata lock

noreply@blogger.com (Unknown) — Wed, 06 Feb 2013 13:34:00 +0000

While trying to execute alter table commands; lately it has started taking lot of time and hangs the server. It keeps executing the query and doesn't show any error. It took me a day to figure out a fix for this issue.

If you happen to get similar error then try doing the following:

Run the command "show processlist";
Run 'kill id" which shows this statement running.

This will terminate the command. But this is not the end of solution. Now while running the "Alter table" command; do the following:

Run "show processlist".
Check for all open mysql connections.
Make sure you close all the connection except the one which you are connected by running kill id command.
Now execute the "alter table" command

This worked for me and I hope this will fix your problem of "waiting for table metadata lock" error.

Maintain Session across subdomain

noreply@blogger.com (Unknown) — Tue, 05 Feb 2013 07:35:00 +0000

To maintain your session variable across the subdomains in cakephp you need to do the following:

Open app/config/bootstrap.php
Add "ini_set('session.cookie_domain', '.domain.com');"

By default Cake is creating a cookie for each domain. With this you can use same sessions across subdomains.

Web server rejects utm_expid

noreply@blogger.com (Unknown) — Fri, 03 Aug 2012 07:41:00 +0000

Web server rejects utm_expid
Your server doesnt support added query arguments in urls

If you receive the above message while validating your Google analytics experiment then try to check the following cases:

1) Open the link which shows the error while validating and do "view source". Check if you can locate the experiment code in the file. If yes, then proceed for step 2. If you are not able to see the experiment code then the code is not mentioned at the correct page.

2) Now add some url parameters to the url. Suppose the url that you are trying to validate is "www.testurl.com", then add few parameters in the url like "www.testurl.com?utm_expid=test&utm_referrer=test". Now see if the page is coming up properly and not going to a 404 or page not found error.
Now, do "view source" and check if the experiment code shows up on the same page as well.

I hope the above two cases will help you debug the issue.

Must haves on your online store or ecommerce website

noreply@blogger.com (Unknown) — Sun, 22 Jul 2012 06:54:00 +0000

Today, I am sharing the tips that are required on your online store for increasing your produts visibility. The sales will increase when the probability of your products appearing on search results or visibility of the products are more.

A section of "featured products" must appear on homepage.
Keep changing the products listed on rotation basis to increase product visibility.
Have an "All Products" page where customers can see all the products on a single page. No need to provide pagination. This can be sorted by category or in an alphabetical order.
Compare Prices : provide an option to compare prices of similar products from your website or other related websites.
Easy navigation to go back to search results page.
Easy way of adding multiple products together to the shopping cart.
Product information should be listed in a proper manner.
Highlight the key specifications and provide all the possible information that may help customers to make their buying decision easier.
Provide an option of contact in case they need any further information for the product before buying.
The product image should be clear and should be same as that of the product being delivered.
The image should not be too heavy to load and provide more (i.e from different angles rear,front etc.) images of the product.
The page should load faster.

If you would like to share some ideas or incorporate the above tips on your ecommerce website or would like to start you own ecommerce website, then contact me for details.

Create your Website

noreply@blogger.com (Unknown) — Thu, 19 Jul 2012 09:36:00 +0000

Creating a website depends upon a lot of factors and your requirement.
If you want to create a website with 3-4 basic pages then you can have it setup and going in a day's time. However, if you want a website which involves user interaction or where lots of content will be uploaded on a daily basis then you will have to go for a content management system (CMS).

You can opt for a static website where the content doesn't change frequently, for eg: a website with only few pages such as About Us, Contact Us page.

Step 1: Decide your domain name

Choose a domain name that is related to your business, company name, or that relates to the content of the website. Once you have decided on the name, check if the domain name is available. You can refer godaddy.com for checking website availability.

Step 2: Register your domain name

Once you have finalized the domain name then you will have to register the domain name. Almost every registrar provides this service.

Step 3: Web Hosting

This is where your website will be hosted and your web pages will reside. Here, you can setup your emails and use the services provided by the web hosting company like blogs, forums, chat scripts etc.

Step 4: Start Building

If you have decided to make a statuc website, then only HTML is required. However, if you want to have a blog or content driven website then you will have to use a CMS and supporting technology like PHP/Mysql etc

If you need help or have any questions related to making a website then Contact me and I can answer your queries.

While using BigCommerce API if you are getting the below error:

" Fatal error: Uncaught exception 'BigCommerce_Api_NetworkError' with message 'SSL certificate problem, verify that the CA cert is OK. Details: error:14090086:SSL "

Cannot modify header information - headers already sent error

noreply@blogger.com (Unknown) — Mon, 20 Feb 2012 05:36:00 +0000

This error ususally comes when we are working with session,cookies,redirects. If you are getting this error then try to follow the below steps to resolve:

Session should be started at the begining of the script and it should be written at the very first line.
There should not be any white spaces before session_start();
If you are using any MVC framework then make sure there are no whitespaces in controller files after the class is closed (after the close php tag " ?> " tag).

Changing CakePHP sessions settings

noreply@blogger.com (Unknown) — Mon, 23 Jan 2012 12:44:00 +0000

CakePHP manages its session inside CakePHP's /tmp directory. To manage cakephp session in wordpress integration add the following lines at the start of wp-config.php

$CAKE_SESSION_COOKIE = 'CAKEPHP';
ini_set('session.name', $CAKE_SESSION_COOKIE);
ini_set('session.cookie_path','app/tmp');
session_start();

Integrating wordpress and cakephp

noreply@blogger.com (Unknown) — Mon, 23 Jan 2012 12:32:00 +0000

In one of my recent project I had a task of integrating Cakephp with Wordpress. The content pages had to be in Wordpress and other dynamic features were coming from CakePHP.

While trying to call Cakephp from wordpress or vice versa I was getting errors like "Fatal error: Cannot redeclare __()". These are mainly because of namespace conflict as Wordpress and Cakephp use some functions with same name.

CakePHP defines its functions in cake/basics.php. When Wordpress is integrated the file wp-includes/l10n.php gets included and has the same function names which results in fatal error.

The alternative is to add:

if ( !function_exists('__') ) :
// the function
endif;

for wordpress functions.

But I tried a different work around.
I kept wordpress and app folder of cakephp on root folder. To use same wordpress theme across the website I moved the header and footer.php outside of theme folder and kept in root.
So that the layout of cakephp also calls same header and footer.

Then I changed the .htaccess file to handle wordpress and cakephp related links separately.

This solved the fatal error issue and I was able to use wordpress and cakephp together in my website without any rework.
