I had to post this note to self as it has driven me crazy for a while it was surprisingly difficult to identify (and locate via search) why jPlayer wasn’t working on Chrome for Android, it must be annoying a lot of people.  This issue occurs in Chrome versions above Google Chrome v.36.0.1985.122 but definitely check it out of you cannot get jPlayer to work in Android Chrome.

The two key threads are here:

https://groups.google.com/forum/#!msg/jplayer/-i-Hb9gs8aM/07rI5BJg-bUJ

Basically highlighting an issue with the “androidFix” process they are required to keep in jPlayer due to the vagaries of Chrome on Android:

The issue related to:

self.androidFix.setMedia = true;

Which you can simply comment out of jquery.jplayer.js (not the minified version which will make things a lot harder!)

Take a look at the issues around Android here

Quote:

“The problem here is that Google keep moving the goal posts.

First of all they took about 4 years to fix a basic bug with the audio element… Simply change the SRC and tell it to play and OMFG that was too complicated. So we had to allow it time for a cup of warm milk and a biscuit in between changing the media URL and asking it to play. To do this, we used the progress event to ensure that the media element was ready and setup with the new URL and ready to play it without throwing the pacifier. We used the progress event as an alternative to the “wait 3 seconds and it should work” solution… After all, we are making every android user wait, so I wanted it to be the absolute minimum and robust time, hence the progress event.
Pretty much as we released the android fix, the mainstream – non google – devices, like Samsung, started working without the fix in the default browser.
In the current Android, the progress event does not fire in the same way as before. Before, changing the SRC would cause the progress event to fire, which we used to apply the fix. Now that never happens, so the fix is breaking all of android.
I am currently looking into other events that we could use for the purpose, otherwise we cannot fix both the old bugs while supporting the current release… And the current release will win if it comes to an ultimatum. ie., Just remove the fix.
It should be noted, that this android fix that I talk of only affected cases where you changed the media, such as a playlist.”

Alternatively you can go to the latest and greatest version 2.71 which contains the fix but at time of writing wasn’t listed on the main jPlayer site:

direct link to script (don’t hotlink – it won’t work, and it’ll need minifiying)
Thanks to the ongoing efforts of the jPlayer team, who do an awesome job on this.

First run of the brand spanking new Intellij 13 – and I get createComponent() returns null for: class com.intellij.execution.RunManager – it turns out to be an issue with plugins, so remove your .IdeaIC13\config\plugins directory and restart you’ll be good to go (sans plugins) – no more createComponent() returns null for: class com.intellij.execution.RunManager issues on Intellij 13!

As much as a note to self as anything else, for some reason it proved hard to find out how I could use html in the auto validation messages generated by models in CakePHP.  Now it’s totally arguable that the use of html is not best practice in this case, the right or wrong of that on a technical level is entirely up to you however assuming you do need/want to use html in the validation messages just make sure that on forms that are applicable you either use a custom form error trap:

e.g.

$this->Form->input(‘yourfield’,array(‘error’=>false);

$this->Form->error(‘yourfield’,array(‘escape’=>false);

OR the simpler mechanism is:

$this->Form->input(‘yourfield’,array(‘error’=>array(‘escape’=false);

As an added benefit assuming you’re wanting to wrap your html validation message in a custom div simply add a class attribute:

$this->Form->input(‘yourfield’,array(‘error’=>array(‘escape’=false,’class’=>’alert alert-error’);

So this is how you put html in CakePhp validation messages!

For some reason wp_redirect/wp_safe_redirect in WordPress can be a total pain, whether it be when writing custom front end code, plugins or widgets I seem to come across an issue with redirects periodically, with the utterly frustrating “Cannot modify header information – headers already sent” error.  As a heads up, this is caused as the name suggests by  content in a header being pushed down before the redirect is called, this is a generic issue not one that is specific to WordPress.  More often than not it is simple to identify, if any of the involved PHP files have leading or trailing white space, and or there’s some hidden debug output you have forgotten.  Occasionally the issue is WordPress however, in my case the issue of wp_redirect not working on a custom admin page, was caused by a function in

/wp-admin/includes/template.php:1636 or so, whereby headers/html, quite a lot of them are indeed sent as part of the page load process.

Having ensured all of my files were trimmed and there was nothing wrong with my plugin code, I discovered here that there’s a little workaround for forms being called in custom admin pages, that is simply to append:

&noheader=true

To your action, e.g.

<form method=”POST” action=”?page=your-plugin-page&noheader=true”>

This resolved my problem instantly – understandably given it suppressed the content being produced in template.php!

Hope it helps anyone having problems with wp_redirect and wp_safe_redirect on custom admin pages in WordPress.

I’ve just spent tow frustrating hours going around the houses, trying to work out how to link my brand new Facebook I-frame app to my fan page.  I’ve done this successfully before, but it was a while ago so this is a note to self.  I’m constantly amazed at how despite such comprehensive documentation it can be so difficult to find things that are so fundamental to how a Facebook app works.  So, in case it helps, to link a  Facebook app to a fan page (other than the page you create for the app) you need to use this url:

https://www.facebook.com/dialog/pagetab?app_id=YOUR_APP_ID&next=YOUR_URL

Obviously replacing the capitalised details.  The app ID is easy – found here in your app settings, the url as far as I can tell can be anything, just cut and paste your app url here and it will redirect you to it afterwards.  When linking your Facebook app to the fan page, the link above will allow you to select which page you want to link to, submit this.

From here, go to your fan page > edit page > apps (in the left nav) and the new app should be listed, from which point you can choose to “link to this tab” and it will appear in your menu on the left.

The information for this was sourced from https://developers.facebook.com/docs/appsonfacebook/pagetabs/ hopefully it will help you with how to link a Facebook app to a fan page.

WordPress is fantastic, what else can you say.  The new custom post types and taxonomies make it a super powerful system that can handle the vast majority of average web content management requirements simply and quickly.  It does have its quirks to be sure, and one of them is the tendency for it to screw up it’s permalink cache at times producing random 404 errors on pages that were working to that point.  This often happens when you change slug values in your functions.php but it can certainly happen at other times.  If this happens the quickest way to sort it (normally) is to reset your permalink structure to the default then reapply any custom paths you have defined.  Volia, old pages back on track, no more random 404s on WordPress.

I’ve spent the last couple of nights working through Centos rebuilds, solr installations, and hook_blocks that just weren’t working the way I wanted them too, so this morning on booting up my newly restored system on encountering “Call to undefined function zen_menu_item_link()” I was just about ready to punch something!

After ranting a bit and the only references online to Call to undefined function zen_menu_item_link() being the error itself on unmaintained sites I took deep breaths and went through my “broken drupal” checklist.  Fortunately on this occasion the problem was fixed by flushing out all the cached variables.  In SQL paste the following:

 

update system s
set s.status=0, s.throttle=0, s.bootstrap=0
where filename = ‘modules/update/update.module';

TRUNCATE cache;
TRUNCATE cache_block;
TRUNCATE cache_content;
TRUNCATE cache_filter;
TRUNCATE cache_form;
TRUNCATE cache_menu;
TRUNCATE cache_page;
TRUNCATE cache_update;

And the drupal issue Call to undefined function zen_menu_item_link() should be no longer!

Having decided to get back onto the blog mission again and redefine my online thang somewhat I chose to combine and remove a few twitter accounts I had been using.  In case you’re wondering about the username change (unlikely, true, but in case you are!) I managed to skip through the clearly presented T&Cs of cancellation by twitter:

So now not only have I closed my old twitter account I’ve also, in the exuberance of changing twitter accounts blocked my original name, @spottmedia.  So two lessons learned, read the instructions and if it’s not broke don’t fix it!

In all the years I have used excel I have never once encountered this problem so hopefully this helps anyone else in the situation.  I have been used to Excel automatically updating its values (say in a sum() column) whenever I change values above, but somehow today it stopped working.  fortunately my better half happens to be an Excel nerd, so with her help I worked out what it was.

If you find that the values in Excel are not updating automatically it is probably because you have not got the (succinctly named) “calculation options” switched to automatic.  Apparently back in the day you were required to press F9 to do calculations at any stage, and indeed this still works, but if you want a more permanent solution in Excel 2007 at least goto:

Formulas > Calculation > Calculation options

Then check the “Automatic” selection.  This should rectify the problem immediately.

Working through an implementation of the Facebook Connect I got caught up in the tangle of documentation that surrounds it and couldn’t work out how to get the session key information so here it is a note to self about how to retrieve the Facebook session key using php client api:

$fbsessionid = $this->facebook->api_client->session_key;
