  • WordPress Questions For Interview: Tell me Would you initialize your strings with single quotes or double quotes?

  • WordPress Questions For Interview: Are there any limitations to a WordPress web site?

    Answer: Not that we have found yet. You can use WordPress for e-commerce sites, membership sites, photo galleries and any other type of site you can think of. The web site is created using the same html code as any other site so there are no limitations there either. I have yet to find a reason not to use WordPress for any client site.

  • WordPress Questions For Interview: Do I need to have a blog in order to use WordPress for my site?

    Answer: WordPress was originally used as blogging software (and still is) though it has since become popular for web sites also. You do not need to include a blog on your web site in order to use WordPress. We have created a number of sites that do not have any blog at all but the client wanted the ability to update content themselves so we used WordPress.
    We do suggest having a blog because it will help with your search engine optimization. Though we only suggest that if you plan on updating the blog on a regular basis, otherwise having a blog without any updates is not going to do you any good.

  • WordPress Questions For Interview: Will using WordPress help my site show up on Google?

    Answer: Yes. That is one of the major selling points of using WordPress is that it includes excellent built in search engine optimization (SEO). With a normal site you would need to include all of the SEO yourself (or hire someone). While it is still recommended that you hire someone for a full SEO campaign if needed, the built in SEO capabilities of WordPress more than enough to get you started.
    We will also install additional plugins to help with your SEO when you first launch the site. These are popular plugins that are known to help your rank on search engines such as Google and Bing.

  • WordPress Questions For Interview: Do I need to know any programming to make updates?

    Answer: To initially setup a site and customize it you will, though you don’t need to worry about that because that is what we are doing for you. Once the site is setup we will train you on how to perform the updates (very simple) and you will be good to go. In order to perform the content updates you may need in the future you will not need to know any programming at all. I compared it earlier to using Microsoft Word and it really is that easy!
    Forget about having to hire a programmer to make simple text updates on your site from now on, you can go in and do it yourself in a matter of minutes.

  • WordPress Questions For Interview: Will I have the ability to update my own content?

    Answer: That depends on the site/project itself. We have created sites where almost every aspect could be edited by the client (content, navigation, photos, forms, etc) and others where it was a simple setup to allow for the main content areas to be edited. This is something we will discuss when planning the project and determine what your need will be. At the very least you will be able to edit the site content yourself and the ability to add/remove photos.

  • WordPress Questions For Interview: Run Any Query on the Database for WordPress

    Answer: The query function allows you to execute any SQL query on the WordPress database. It is best to use a more specific function (see below), however, for SELECT queries.
    query(‘query’); ?>

  • WordPress Questions For Interview: Does the 644 permissions on wp-config.php compromise the username and password to all other users on my shared server?

    Answer: This is a limitation of the way PHP is set up on your server. If you previously used MovableType, Perl was probably set up with suexec so Movable Type executed as your user. In this case, PHP is running as the web server user, which is why it has to be at least 444. There is phpsuexec but it seems many hosts don’t use it.
    However this is often not an issue on modern shared hosts because even though the file is “world” readable each account is set up with a “jailshell” which keeps people locked in their home directory, and PHP can be easily modified with an open_basedir restriction to keep people from writing PHP scripts to read your files. If you are really concerned, you should contact your host to see what measures they are taking.

  • WordPress Questions For Interview: How do I prevent my images from being hot-linked by another website?

    Answer: You can use your .htaccess file to protect images from being hot linked, or, in other words, being linked-to from other websites. This can be a drain on your bandwidth, because if someone links directly to the image on your site, then you lose the bandwidth.

  • WordPress Questions For Interview: How do I prevent comment flooding?

    Answer: Comment flooding is when a lot of comments (probably spam) are posted to your website in a very short duration of time. This is only one aspect of the broader problem of comment spam in general, but it can quickly overwhelm a moderator’s ability to manually delete the offending comments.
    WordPress manages the worst floods automatically by default. Any commenters from the same IP or e-mail address (other than registered users with manage_options capabilities) that post within 15 seconds of their last comment gets their comment discarded. The time setting can be changed by a number of plugins that extend this functionality. You might also consider one of the many broader spam blocking plugins, such as Akismet, or even turning your comment system over to Disqus.
    You could also just change the time setting by directly hacking the core file, but the correct way would be to create and install a very basic plugin and insert the following code:
    function dam_the_flood( $dam_it, $time_last, $time_new ) {
    if ( ($time_new – $time_last) < 300 ) // time interval is 300
    return true; // seconds
    return false;
    }
    add_filter(‘comment_flood_filter’, ‘dam_the_flood’, 10, 3);

  • WordPress Questions For Interview: How do I redirect users back to my blog’s main page after they login?

    Answer: By default, WordPress reroutes a registered user to the Administration Panels after they log into the blog. To change the page, there are WordPress Plugins that can handle the redirect, or you can set the Theme function to handle it. See Function_Reference/wp_login_url.

  • WordPress Questions For Interview: Why can’t I delete the uncategorized Category?

    Answer: Any Category with a non-zero value for # of Posts in the Administration > Manage > Categories cannot be deleted. The uncategorized Category might be assigned to some Posts, but all Pages are assigned the uncategorized Category. So even though there may be no posts assigned to the uncategorized Category, Pages are included in the count of # of Posts.
    The default category cannot be deleted even if it is empty, however you can specify your default categories for posts or links on the Options – Writing page of the admin panel.

  • WordPress Questions For Interview: How can I have a static front page and posts display on a page called Blog?

    Answer: If using WordPress as a CMS, you might want to present readers with a static front page, and then display your posts on another page called Blog. To accomplish that follow these instructions:
    Create a Page and use “My Front Page” for the Page Title. Of course, in the content for that Page, you can enter the information you want presented on your site’s front page (see example below if you want to display a post).
    Create a Page and call it Blog. Nothing needs to be entered in the content field of this Page.
    In Administration > Settings > Reading set the Front page displays to A static page, and select My Front Page for Front page:, and select Blog for the Posts page:.
    If you want to further customize your front page, you can create a Template, and fit it to meet your needs:
    With the help of the Template Hierarchy article, determine what Template is normally used to display your Pages (e.g. page.php or index.php).
    Copy that template to myfront.php. If you were using the WordPress Default theme you would copy wp-content/themes/default/page.php to wp-content/themes/default/myfront.php.
    In Administration > Appearance > Editor, edit the myfront.php and change the beginning of the file from:
    <?php
    /**
    @package WordPress
    @subpackage Default_Theme
    / to:
    Template Name: MyFront
    / ?> Then access the Page called Front in Administration > Page > Edit and set the Template to MyFront. Once that’s all working, begin changing myfront.php to make it look like what you want. That’s it. You are done. Use this example for the ‘MyFront’ Page Template if you want to display one post, instead of the Page content, on your ‘static front page’:
    Template Name: MyFront
    */
    ?>

  • WordPress Questions For Interview: How do I disable comments?

    Answer: First, unchecked Allow people to post comments on the article on the Options > Discussion panel. This will only disable comments on future posts. Now, to completely disable comments, you will have to edit each past post and uncheck Allow Comments from the Write Post SubPanel. Alternatively, you could run this MySQL query from the command line on a shell account or using phpMyAdmin: UPDATE wp_posts SET comment_status=”closed”;
    If your goal is to permanently disable comments, then you should delete the wp-comments-post.php file as well.

  • WordPress Questions For Interview: How can I hide my blog from people?

    Answer: Whether you are testing a new version of WordPress, setting up a new blog or have some other reason to limit access, the following information may help you keep unwanted visitors out.
    Apache
    There is no guaranteed way to do this. You can use the .htaccess file (which also contains your permalink code) to check for certain IP addresses and prevent them from viewing your site. This will only stop the IP address, not the person, so if they have access to an allowed IP address, they can get to your page. One tutorial for this is located at Clockwatchers.com
    An .htaccess file can also be used to prevent others from “hot-linking” to your images (bandwidth theft) or to set up a password protected blog.
    Apache Basic Authentication
    To require a password to access your site using .htaccess and .htpasswd: Clockwatchers.com .htpasswd.
    Tools that help you create the files necessary to password protect your site: Clockwatchers.com .htaccess And .htpasswd Tools
    Note: When your site is accessed the password is encoded weakly using Base64 and can be easily intercepted and decoded.
    Windows IIS Basic Authentication
    To require a password if your site is hosted on IIS, you can deselect Allow Anonymous Access and select Basic Authentication. You’ll also need to have a username with a password.
    Note: When your site is accessed the password is encoded weakly using Base64 and can be easily intercepted and decoded.

  • WordPress Questions For Interview: How can I get WordPress working when I’m behind a reverse proxy?

    Answer: In some setups, it’s necessary to use something other than the HTTP_HOST header to generate URLs. Reverse proxies take the original request and send it to one of a group of servers. To do so, it overwrites the HTTP_HOST with the internal server’s domain. When that domain is not publicly accessible, at best your images might not load correctly, at worst, you’ll be stuck in a redirect loop. To fix this, figure out which header has the right domain name and add a line to your wp-config.php file that overwrites HTTP_HOST with the correct hostname.
    If you need to use SERVER_NAME, add this line to wp-config.php:
    $_SERVER[‘HTTP_HOST’] = $_SERVER[‘SERVER_NAME’];
    If you need to use HTTP_X_FORWARDED_HOST, add this line to wp-config.php:
    $_SERVER[‘HTTP_HOST’] = $_SERVER[‘HTTP_X_FORWARDED_HOST’];

  • WordPress Questions For Interview: Do I really need MySQL?

    Answer: You certainly need the MySQL database server to power your WordPress blog. In fact, WordPress only supports the MySQL database server. Listed are the PHP and MySQL requirements:
    WordPress server requirements for Version 3.2:
    PHP version 5.2.4 or greater
    MySQL version 5.0.15 or greater
    (Optional)(Required for MultiSite) Apache mod_rewrite module (for clean URIs known as Permalinks)

  • WordPress Questions For Interview: Can I use a database other than MySQL?

    Answer: Other databases are not supported at the moment.
    There are several other excellent database storage engines, such as PostgreSQL and SQLite that WordPress is interested in supporting in the future. Supporting multiple databases is trickier than it sounds and is not under active development, although there are plenty of architectural discussions about the best approach to take. Approaches for increasing the number of supported databases are discussed at Using Alternative Databases. There is a PostgreSQL port of WordPress available called WordPress-Pg.

  • WordPress Questions For Interview: Why does WordPress use MySQL?

    Answer: MySQL is extremely fast. It is also the most widely available database server in the world. Open-source and free, MySQL is supported by thousands of low-cost Linux (and Windows!) hosts, which means a very low barrier to entry for anyone wanting to start a WordPress (or database-driven) website. MySQL’s documentation is useful, cogent and thorough. (Note: it may be intimidating if you are new to all this.) Add to all that the fact that users are able to directly manipulate MySQL with phpMyAdmin, developed expressly for that purpose, and it is obvious that MySQL is the best choice. Of course, WordPress insists on the best.

  • WordPress Questions For Interview: What is XML-RPC?

    Answer: Overview
    XML-RPC is a Remote Procedure Calling protocol that works over the Internet.
    An XML-RPC message is an HTTP-POST request. The body of the request is in XML. A procedure executes on the server and the value it returns is also formatted in XML.
    Procedure parameters can be scalars, numbers, strings, dates, etc.; and can also be complex record and list structures.
    Request example
    Here’s an example of an XML-RPC request:
    POST /RPC2 HTTP/1.0
    User-Agent: Frontier/5.1.2 (WinNT)
    Host: betty.userland.com
    Content-Type: text/xml
    Content-length: 181
    examples.getStateName 41
    Header requirements
    The format of the URI in the first line of the header is not specified. For example, it could be empty, a single slash, if the server is only handling XML-RPC calls. However, if the server is handling a mix of incoming HTTP requests, we allow the URI to help route the request to the code that handles XML-RPC requests. (In the example, the URI is /RPC2, telling the server to route the request to the “RPC2″ responder.)
    A User-Agent and Host must be specified.
    The Content-Type is text/xml.
    The Content-Length must be specified and must be correct.
    Payload format
    The payload is in XML, a single structure.
    The must contain a sub-item, a string, containing the name of the method to be called. The string may only contain identifier characters, upper and lower-case A-Z, the numeric characters, 0-9, underscore, dot, colon and slash. It’s entirely up to the server to decide how to interpret the characters in a methodName.
    For example, the methodName could be the name of a file containing a script that executes on an incoming request. It could be the name of a cell in a database table. Or it could be a path to a file contained within a hierarchy of folders and files.
    If the procedure call has parameters, the must contain a sub-item. The sub-item can contain any number of s, each of which has a .
    Scalar s
    s can be scalars, type is indicated by nesting the value inside one of the tags listed in this table:
