How To: Create aliases on WAMP server

If you are looking for a quick and easy ways to create server aliases, WAMP server is your answer.

What is an Alias?

Let us assume that you are using the document root for main site, and you want to direct the server directories outside the document root. For example, you want to map following:

  • Students -> C:students
  • Teachers -> C:teachers
  • Principal -> C:principal

WAMP server interface by default allows you to quickly set up aliases, but they might not work.

Adding Aliases from WAMP Interface

Left-click the system tray icon and then go to the Apache -> Alias Directories -> Add An Alias

How To: Create aliases on WAMP serverA command prompt will open prompting you to create the alias URL

How To: Create aliases on WAMP server

Type the names of the alias; this will be what is added onto the http://domain_name/address e.g. (http://www.webtamarin.com/students)

Enter the location of the folder that will house the pages for this website. keeping with our earlier example, type C:students and then hit Enter.

The alias will now set up according to WAMP.

Don’t panic if the alias doesn’t work.

When you create the alias using the WAMP server, it creates the necessary file in the correct location, but it adds all the content in one line

 The file should look like

To edit that file, follow these steps:

  • Left-click the WAMP icon in the system tray.
  • Go to Apache -> Alias Directories -> ALIAS_NAME -> Edit Alias (here ALIAS_NAME is the name of the alias you just created).
  • In the Notepad window which just opened, edit the configuration file to reflect the above contents and save it.
  • Edit the configuration file to best fit your needs (according to the Apache specifications).

Restart the WAMP server, and you should be able to point your browser to http://localhost/students. (Of course, you’ll need content within the C:students directory.) If you get an error, check to make sure the alias directory’s permissions allow the server to read the contents; this will be dictated by a number of issues, such as whether the server resides on a Windows domain.

Fix: WordPress Memory Exhausted Error – Increase WordPress Memory Limit

Sometime you might have to face an error while activating a new plugin or doing some other stuff. This error might look like:

 The most possible reason for this error is that you have exceeded your default Memory Limit.

Since WordPress 2.5 there is a wp-config.php option WP_MEMORY_LIMIT which allows you to change the maximum amount of memory allocated to your website. If you change this option for your website it will only affect your WordPress website and not other PHP websites on the server.

WordPress allocates 40MB for single websites and 64MB  for multisite installation. But the php.ini allocated memory supersede the wp-config.php value. For example, if php.ini is configured to 64MB and your WordPress allocated 40MB memory, then the website will 64MB not 40 MB memory.

There are number of ways to fix this error. Some are listed below:

From wp-config.php

To change the WordPress memory limit you just add the following into the wp-config.php.

WordPress memory can be different to the server – you need to set this regardless of server memory settings

From php.ini

If you have access to your php.ini file, then you can change the line in php.ini. Search for the property memory_limit and change the value to something greater like 64M

 From .htaccess

If you don’t have the access to php.ini file you can change the memory limit from the .htaccess file. Go to the root folder of your website and create a new .htaccess file if it doesn’t already exist and add the following line to your htaccess file.

 If none of the above methods work, please contact your hosting service provider.

Everything about WordPress Child Themes

As more and more WordPress users now customize their themes and only few users like the themes in default mode we will learn in this article how to create a Child Theme from a WordPress Theme.

Why use a Child Theme?

You will save yourself from a lot of headache by creating a child theme. Child theme allows you to make changes without affecting the original theme, which will in turn make it easier to update your parent theme to latest versions without loosing all the changes you made. In the child theme you create a completely separate set of files that you can use to customize the theme without affecting the original theme. This way you will make sure that your original theme is intact as you are not making any changes to it.

Getting Started

  1. Create a new folder/directory in your themes folder. This new folder will contain you child theme. For our reference we will create a child theme of WordPress Twenty Fourteen Theme.
  2. In the child theme folder create a stylesheet file named style.css. This is the only required file for a Child Theme. Open the newly creates file and put the following code at the top.

    You can make changes to the above code according to your suitability. Only Theme Name and Template are required, all the rest are optional. The Template value is the name of the directory of the parent theme.

  3. Go to your website’s dashboard, and go to Administrator Panel -> Appearance -> Themes. Here you will now see your newly create theme among the list of other themes. Activate the Child Theme.

Editing the functions.php File

The functions.php of a child theme does not override its counterpart in the parent them unlike style.css. It is loaded in addition to the parents function.php not in place of it. Your child theme’s functions.php file should start with a php opening tag and end with a php closing tag. In between, you can add your desired php code.

 For example, you want to add a new function to you theme, the fastest way is that you open your theme’s function.php and add the new function. But now if you update your theme the new function added by you will be removed. The better way is that you add the new function toy your child theme’s function.php. 

Editing Other Templates

If you want to make structural changes to your theme by changing PHP template files, this can be done by replacing the file entirely with a new one  in your child theme. Your child theme can override any file in the parent theme: simply include a file of the same name in the child theme directory, and it will override the equivalent file in the parent theme directory when your site loads. For instance, if you want to change the PHP code for the site header, you can include a header.php in your child theme’s directory, and that file will be used instead of the parent theme’s header.php.

Decoding WordPress wp-config.php

wp-config,php is one of the most important file of a WordPress installation. This file is located in the root of your WordPress file directory and contains your website’s base configuration details, such as database connection information. In this article we will try to understand all the settings that are done in wp-config.php and their usage.

Database Settings

  • DB_NAME: This will be the name of your WordPress database.
  • DB_USER: This will the username to access your database.
  • DB_PASSWORD: This will the password to access your database.
  • DB_HOST: This will the hostname of your database server. Most of the times its localhost. But if you are not sure you can ask you hosting company and they will provide you the database server information of your server. Below is a table of possible database hosts.
  • DB_CHARSET: This will define the character set used by your database.The default is utf8 which supports all languages, so it should not be changed unless absolutely necessary.
  • DB_COLLATE: Used to define the sort order of the database character set. if you are changing this value, make sure is is set to a UTF-8 character set, such as utf8_general_ci or utf8_spanish_ci

Table Prefix

The $table_prefix is the value placed in the front of your database tables. If you haven’t changed this while installing the WordPress, then most probably you are using the default wp_ as table prefix.  From security perspective, this is very unsafe and this should be changes as soon as possible. If you are an advance user you can change it manually by replacing wp_ by something random like aedc_ and then updating the database tables. But if you are not and advance user you can do it by using some security plugin such as iThemes Secutiry.

You can have multiple installations in one database if you give each a unique prefix.

 A second blog installation using the same database can be achieved simply by using a different prefix than your other installation.

Security Settings

A secret key is a password with elements that make it harder to generate options to break through you security barriers. All the keys are randomly auto-generated and should not be disclosed to anyone.

You can assign any random string to these keys or you can use the online generator to generate security keys.

These keys will be used to sign the cookies for your website.

  • AUTH_KEY: This key is used to sign auth cookies for the non-SSL. These can also be used to make changes on the blog.
  • SECURE_AUTH_KEY: It is used to sign an auth cookie for SSL admin and these cookie can be used to make changes on blog. (With the new version there will be two type of auth cookie one for SSL and other for non-SSL)
  • LOGGED_IN_KEY: It will be used to generate a cookie for a logged in user and this cookie can’t be used to make changes on the blog.
  • NONCE_KEY: It is used to sign the nonce key which protects the nonces from being generated, protecting you from certain forms of attacks where a hacker attempts to guess the nonce.

Salt is an addition to the secret keys. They work in combination with keys.

There are 4 salts named as AUTH_SALT, SECURE_AUTH_SALT, LOGGED_IN_SALT, and NONCE_SALT.

Defining them is not compulsory, but it is a good practice to have them in your wp-config.php file. If you don’t define those than WordPress will generate it automatically. These can also be a random complex string and you can define them either by yourself or through the online random key generator.

Language and Language Directory

  • WPLANG: It defines the name of the language translation (.mo) file.If your blog is in English, leave it blank. But if your blog is in a language other than English, you can look up your language code here: http://codex.wordpress.org/WordPress_in_Your_Language. For example, for Spanish the code will be 
  • WP_LANG_DIR: This defines what directory the WPLANG .mo file resides. If WP_LANG_DIR is not defined WordPress looks first to wp-content/languages and then wp-includes/languages for the .mo defined by WPLANG file.

Debug Settings

  • WP_DEBUG: This option controls the reporting if errors and warnings. This is set to false by default. But if you wish to debug code you must set it to true.
  • CONCATENATE_SCRIPTS: This option will concatenate all the JavaScript into one for a faster Administrator area. This is set to true by default, but if the JavaScript is not working properly in your Administrator area you can set it to false.
