WordPress has a great facility that allows you to schedule posts to be published at specific times on specific days. This is very handy if, say, you may write a number of posts at a time but wish to spread their publication out over a longer period of time.

However, during the many years I’ve used WordPress I’ve been plagued with the schedule being missed. When the schedule is missed, WordPress doesn’t even attempt to resolve it – it simply tells you (and only then when you list your posts in the administration screen) that the schedule has been missed. Great, but if you know that, why not make it live now?

The WordPress forums have been full of people reporting this for a long time, and still are. However, the current advise seems to be the WordPress equivalent of “turn it off and on again” – deactivate all your plugins and re-load your WordPress installation, as the issue is apparently fixed. Yes, it must be a plugin fault. Which is odd because the Trac system that WordPress use to record bugs and fixes appears to have numerous tickets open related to post scheduling, some of which show fixes that have been made but have been awaiting review for 7 months.

In fact a recent update to the Akismet plugin, written by Automattic, the company who also produce WordPress, stated that one of the changes was…

Prevent retry scheduling problems on sites where wp_cron is misbehaving

That would certainly suggest to me that there is a known issue.

I’ll admit to not understanding what the issue is.  I still get it and I was approached by another WordPress user at BlogCampUK with the same issue last Saturday – and the WordPress forums prove that this affects others too.

Plugins exist to try and resolve the issue and there are also suggested changes to WordPress to ease the issue, even if they can’t resolve it. If you try anything that seems to resolve the problem, please comment and let me know!

is a great way to moneterise a blog. Once signed up and approved you simple need to add a line of JavaScript to your site and it will add moneterised links to your output. However, you may be adding sponsored posts or your own links and may not want Skimlinks to modify the entire, or portion of, the post.

I was recently asked, as a commercial request, to create a WordPress plugin that would allow users to click a button and copy text the clipboard. It seemed an easy enough thing to do – 2 weeks later, though, and I’ve thrown in the towel.

Using JavaScript to capture contents is the easy bit – adding it to the clipboard is a lot more difficult. IE has a JavaScript command built in, other browsers vary. Unfortunately, other browsers (e.g. Firefox) also restrict this ability for security reasons. This is because the ability to write to the clipboard also comes with the ability to read from it as well – quite why this functionality can’t be detached and restrict just the reading I don’t know.

So, using JavaScript is problematic.

Thankfully I’m not the first to come across this problem and a third party script named ZeroClipboard is available. This uses Flash to update the clipboard, which doesn’t have the same security limitations. Of course if you’re viewing from a device that doesn’t support Flash (cough, splutter, iPad, iPhone, cough) then you’re still out of luck. None-the-less this seemed a perfect solution.

Unfortunately, my limited JavaScript skills failed me – I found the program to be over-complex for what I needed and failed to be able to get it to work.

At this point I found an alternative – ZClip uses ZeroClipboard but is controlled via JQuery (which is built into WordPress) and provide a much easier and friendly method of access.

I was now in a position where I had a working plugin. Until I used Admin Bar. That seemed to affect the positioning of the Flash overlay so you had to click slightly above the “Copy to clipboard” button to get it to work.

The customer, though, didn’t have an issue with this and I could only hope that they didn’t have anything else within their theme or plugins that could affect it in this way (I did try contacting the developer of Zclip but got no response).

What really ended it all though was the limited way of capturing text in zclip, which I hadn’t appreciated earlier on. ZClip can capture in 2 ways – from static fields (e.g. the text between a SPAN) or dynamic (e.g. from a field). The first doesn’t capture any formatting, even paragraph breaks – returning everything as one long line of text. The second did, but by capturing the HTML.

The customer wanted the customer to be able to copy to the clipboard long paragraphs of text – neither offered a neat solution to this.

Then I gave up. One day I may return to it – certainly ZeroClipboard will probably allow me to do what I need it to, but I’ll have to get my head around how to first.
