When we start using Custom Post Type & Custom Field to enrich our WordPress website, to meet various real world situation, building relationship between different datasets becomes a common practice. A simple example, is project & client relationship. If we manage this in database, we always link client to project using client ID, because client may repeat in multiple projects. If we use Custom Post Type to manage project and client in WordPress, the challenge is: how do we dynamically populate a latest client list into a client choices for a project?
Take Control of Post Revisions
WordPress revisions system saves a record of each saved draft or published update. This feature is important to site owners, because it provides some sort of “backup” for the content in case you accidentally edit posts the wrong way. By default, WordPress saves every copy of revision when you click Save button. All the revision copies take up room in database, will eventually slow down the query time, especially on sites with many blogs.
Restore Custom Post Type from History that doesn’t have Revisions Enabled
I know the title sounds a little wired, here is the background story. WordPress has Revisions system stores a record of each saved draft or published update. It is enabled for Post & Page. But in Custom Post Type, Revisions support is up to the theme developer to enable it. As long as you use themes, you should have noticed that, in some themes, the revisions is disabled on Custom Post Type by default. When Custom Post Type is used for short content such as Testimonial, it isn’t much of trouble to restore a revision. But not for a CPT post with a lot of content.
Quick Fix for Working with Absolute Path on Temporary URL
Can’t think of a better title, here is the scenario: After creating a new account at hosting service provider, we are normally assigned a temporary URL before link this hosting account to domain of final production site, for example: http://hostingserver.com/~username. Sometimes, we have to work on the temporary URL through development stage before site goes live for various reasons. The temporary URL creates temporary trouble to some not well-written code in case “absolute path” is used in either themes, plugins, or existing site. The trouble can be either broken links, or missing images.
Download failed. Failed to write request to temporary file.
When trying to update stock Twenty Fourteen theme today, I ran into a theme update failing problem. The error message is “Download failed. Failed to write request to temporary file.”. The first reaction was file / folder permission setting. But it wasn’t the case this time.
How to Make TubePress Responsive
TubePress is a well-designed plugin that brings YouTube or Vimeo video gallery into WordPress website. With easy CSS hack, we can easily fit TubePress video gallry to different theme. But out of the box, TubePress doesn’t offer responsive option.
Redirect User Registration to Custom Registration Page
Let’s say we’ve customized a beautiful user registration form, with extra fields, well-designed interface blending nicely with the theme. But how about when you type in this url:
http://url/wp-login?action=register
Well, because we allow “Anyone can register” in general settings, the register link is open to public. Which will lead visitors to the default registration page you wanted to hide at the first place.
Troubleshooting: BackWPup Next Cron Job at Dec 31, 1969
As usual, on the new website, I created few backup jobs in BackWPup (Free) – my favorite WordPress backup plugin, setup the scheduled start time with WordPress cron. Because I setup one daily backup also send a copy to Box.Com via email, which will trigger an automatic notification email from Box.Com, I get to know if the scheduled backup is executed on time. But something strange happened after the following two days. The scheduled backup didn’t start as expected.
