Optimize WordPress database perfomance

Optimize WordPress database

Optimize WordPress database perfomance – every blog owner got this conclusion, ealier or later, but finally always.
Any site owner asks himself, how can I make my site lighter and faster. What else should I do? What technique to apply? General site speed is critical property for present days. As there are a lot of alternative variants where web-surfer may find and get the same information, large part of visitors do not wait, while their browsers finish download process of slow page. They just return to search engine and click on the next link from the huge list of available sources. This way, we (site owners) lose auditory and, as a result, have a lower traffic. And WordPress blogs are not exclusion. The same general rools are in action for our loving WordPress too. It doesn’t matter, what platform do you use, in order to build your site. It does matter, with what speed your platform delivers content to your site’s visitors.
Reliable hosting service provider; fast and powerful server; wide, high-speed, broadband, backbone channel; popular and effective publishing platform – all of these factors are important and valuable in relation to the final result – your site speed.

single.php is called twice – how to stop

October 30th, 2012

Stop double content rendering

Stop double execution

single.php is called twice for every post view – that was my conclusion after some investigations. How I’ve got it?
Trying to build the list of recently viewed posts I added simple tracking code into my active “Twenty Eleven” theme single.php template file. After that I’was wondered as I’ve got two records in my log instead the only one after any post view. First valid record for just viewed post and second unexpected record for post, which is chronologically next to the viewed post.
Thus WordPress post content rendered at least twice every time visitor clicks on its permalink. It is obvious and unneeded overhead for my opinion. Why it is happened? How to stop this weird behaviour?

Hide Login WordPress plugin review

Hide Login WordPress plugin

Hide Login

Hide Login is the direct ancestor of the Stealth Login WordPress plugin. Mohammad Hossein Aghanabi (parswp) tries to give it new life after Stealth Login was removed from WordPress repository as updated last time too long ago. In respect to author of original plugin Mohammad left the comment at the begin of hide-login.php file: “This is a new version of Stealth Login plugin by skullbit”. Features list is the same. Short description is available here – Stealth Login WordPress Plugin Review.
I tested new 2.1 version of Stealth Login, Ups!, excuse me, Hide Login plugin under WordPress 3.4.2. It was a pretty fresh WordPress installation. And I can say that Hide Login WordPress plugin worked well for me, but not too long. I discovered that ‘logout’ slug doesn’t lead to the real logout, just redirects to the home page, while you are still left logged in.

edit_theme_options capability for WordPress user

September 28th, 2012

edit-theme-options WordPress user capability

edit-theme-options user capability

‘edit_theme_options’ capability seems to be self-explained. It’s primary purpose is to provide access to WordPress front-end theme options changing.
On practice, if you have ‘edit_theme_options’ capability, then you have access to the ‘Appearance’ menu at WordPress admin back-end and to its menu items: “Themes” (select a theme for your WordPress front-end) and “Menus” (edit menus supported by your selected theme). Customize theme header image, background color, etc. section and ‘Widgets’ menu items require ‘edit_theme_options’ capability also.

How it is realized? How often and at what places WordPress uses/checks this user capability – ‘edit_theme_options’ in order to decide give current user permission to edit theme options or prohibit access to such functionality? Let’s check this together. We will make a quick look into WordPress version 3.4.2 core source code and comment its related fragments.

Stop! Rest a litle, look around – there is a real life beyond the boring office and amazing, but virtual Internet. Take a minute, book hotels with a couple of clicks. Fly to old Europe. Rent a car.

That was my dream for all this year and it will become reality tomorrow. Let me leave you for next 2 weeks. I take a vacation and go to my year 2012 Europe holiday trip: Germany, France, Belgium, Wiesbaden, Constanz, Paris, Mont-Seint-Michel, Gent, Brugge, Frankfurt. Go-go-go!

User Role Editor 3.8 is published

September 2nd, 2012

User Role Editor

User Role Editor

User Role Editor WordPress plugin version 3.8 is published at September 1st, 2012. What’s new?
- Bug fix: Some times URE didn’t show real changes it made to the database. The reason was that direct database update did not invalidate data stored at WordPress cache. Special thanks to Knut Sparhell for the help with detecting this critical issue.
- WordPress core capabilities are shown separately from capabilities added by plugins and manually.
- If you configured URE to show you ‘Administrator’ role, you will see its capabilities, but you can not exclude any capability from it. I may just add capabilities to the Administrator role now. The reason – Administrator role should have all existing capabilities included.
- Brasilian Portuguese translation is updated.

Change published to pending after update

Change Published to Pending

Published to Pending

What to do if you wish to approve all changes made into published post by their authors? It’s possible by changing post status from ‘Published’ to ‘Pending Review’ automatically. You need just add a piece of code placed below to your current theme functions.php file. It works for users with ‘Author’ role. If you wish to change it, then change ‘author’ in the code to role name you wish to use.
Is that all you need to do? No. You should remove ‘publish_posts’ capability from your users, otherwise user can to publish pending post himself again. Use User Role Editor plugin for that.
Do you wish to see how does this hack work? Let’s proceed with short video demonstration.
