Hello, I think I get carried away with few things. While I was working on detecting Arrow keys I wrote a simple jQuery plugin for Page navigation. It could be useful perhaps. More needed to be done like preserving state and ajaxifying it. While still on this note I wrote a Wordpress plugin putting my jQuery plugin to its core. Wordpress plugin is called "jcwp left right key navigation" Here are couple of screenshots as shown below ScreenShot 1 Screenshot 2 So the Idea of this plugin is that when someone press right arrow key one then a title of next post is picked and shown automatically and when a user press the right arrow key again (twice in a row) then user is taken to a next post. Same applies to the left key pressing. When left arrow key is pressed once then the previous post title is shown to the user and when left arrow key is pressed twice in a row then user is taken to the previous post. To hide the preview press any other key or ESC key. Features Disable the plugin function without uninstalling it. You can put your own text for Next and Previous labels. You can specify if the next and previous post should be picked from same category. You can pick up a theme. RIght now only theme that is supported is "grey" Where to get it from As you know that because of lack of donations and very heavy bandwidth to some of my stuff I have stopped hosting plugin files on my blog, the other reason was that it was maintenance nightmare when I issue an update to my plugins instead I host them permanently with wordpress now and you can get it from wordpress from the url below http://wordpress.org/extend/plugins/jcwp-left-right-key-navigation Or simple search for "jcwp" Installation 1. Upload unzipped plugin directory to the /wp-content/plugins/ directory 2. Activate the plugin through the 'Plugins' menu in WordPress 3. Use the Plugin Options on left menu under Settings > JCWP Left … [Read more...]
WordPress Get next and previous post URL permalink
Hello, This post as the title says talks about getting URL for next and previous post. Please note that post is not same as page. All the required functions and hints can be found in link-template.php file under wp-includes Let me show you how you can get permalinks for next and previous post without doing anything fancy. Get Previous post URL First of all we will get hold of post object for the previous post as shown below We will use adjacent_post_link() function. Definition of this function is given below [crayon-64832ee0b749e364130004/] So to get the previous post link do this [crayon-64832ee0b74a2001084317/] Above usage of function get_adjacent_post pass on default values for all the params function accepts. You can pass on custom values for it to behave differently. Now lets check how we can get next post permalink Get Next post URL Pretty much the same functionality but with one core difference. $previous should be set to false as shown below [crayon-64832ee0b74a4015395127/] As you can see that its pretty straight forward. I hope this helps. Please let me know if you have something to add of the above code can be improved. Don't forget to leave you comments. Once again I would like to add that getting post link is not same as getting page link. Here is a useful read from wordpress codex http://codex.wordpress.org/Next_and_Previous_Links The above post explains how to get page URLs. If you have any questions please let me know so that either myself or any other reader reading this post can answer your question.s Cheers … [Read more...]
wordpress simple table of contents plugin
Hi Guys, Well I thought this could be a good addition to my Blog if I end up offering Table Of Contents for visitors to browse an article more efficiently. That's when I decided to go ahead with this plugin. This plugin is called "JCWP Simple table of contents" What does this plugin do? Well it created a table on contents for your post completely on client side without putting any extra pressure on load times of your article. Here are some screens that will tell you what this plugin does Let me explain a bit what above settings means Enabled: You can enable or disable this plugin without actually deactivating the plugin. When you disable this plugin that means Table of contents will not appear at all. Article parent Tag: You will seldom need to change this because its standard all across the WordPress Blog. However if your article is wrapped in some other class other than .entry-content then you will need to mention it here. Scroll speed: You can control scroll speed when user is browsing from header A to header B Text length per Item: Sometimes out header text is way to long. You can limit the number of characters displayed in the Table of contents by setting this value Fancy Scroll: This plugin can make use of jScrollPane, you can beautify your TOC scroll by setting this value. A scroll will appear when height of your TOC exceeds the Table default height that you set. Auto minimize: Yes if you don't want TOC always visible to the user. User hovers on TOC triggers show/hide of TOC Default height: I would recommend that it should be atleast 300px but you can set it to whatever you like. Table title: Default is "Table of contents" I recommend that you shouldn't set it more than 30 character in length. Easing animation: Just in case you want something other than linear animation when scroll happens. Position: Position your TOC to wherever you like it. Powered by: Well this is my 5th WP plugin and your support matters to … [Read more...]

More information can be found here http://codex.wordpress.org/Function_Reference/is_single by the way is_post() has been deprecated and should not be used. Check if type is HOME PAGE/Front page This is a common occurrence with many plugins trying to do some really specific things on home page. Such as displaying ads etc. Wordpress supply two functions called is_front_page() and is_home() Here is a quick usage on that. [crayon-64832ee0b7925993782361/] Both of the above function will print home page when tested is_front_page is based on Settings->Reading->Front page displays setting, if it is is set to "Your latest posts", or when its set to "A static page" or "Front Page" value and the current Page being displayed is same as selected page this function returns true. is_home on the other hand is … [Read more...]

I'll put maximum distance to 10px. Opacity: is tooltip opacity Link to author website: Just if you would like to support me and my work. Check that checkbox.

wordpress scroll to top plugin
Hi guys, As you may be aware that I released Scroll to top plugin for jQuery in the past. Now it was time to take that to another level. I found well may be second level of that would be wordpress. So I came up with one. The plugin is free and just in case you found yourself to be generous enough you should be able to think a little bit and consider donations. Why? because it take real money to host files and make them available for download. But that not the reason. Then reason it that I put lot of effort to come up with solutions that could help someone and most of them free of cost. hmm... hopefully I am making some sense :) Ok lets start with couple of screenshots that will tell the story about what this plugin does. Demo Scroll a bit and you will see the STT layer pop up in the centre of browser window with red background. Try to click on that and see if it takes you to the top of the page or not. Screenshots Settings View on Page Alright now you know exactly what this does right. So consider donations before you download :) :) kidding.. Donations Alright now that we are over the donation part let me explain what each of the settings means. Settings Active you can choose value of this settings as yes or no when you choose no then "Scroll to top" layer will not appear at all when user scrolls down. Duration The time it will take to scroll up. I recomment 1000 milli seconds. The longer this value is more frustrating it becomes. Scroll Activate At This setting tells the plugin at what depth you would like to show "Scroll to top" layer Scroll Container ID Just give a unique ID to STT text container Easing Type Select what easing animation type you would like to run Position The layer is fixed at bottom but you have flexibility to show it either at bottom-left or bottom-center or bottom-right Scroll Text If you don't like "Scroll to top" then choose whatever … [Read more...]

Using open flash charts in wordpress plugins
Hi Guys, Open flash charts by John Glazebrook. His charts tool is highly customizable solution and is very potent in what you can achieve. Today I am gonna show you how you can use OFC2 within a Wordpress Plugin. There are two ways I am going to show you of using OFC2. First feeding the JSON string directly to the Chart Processor SWF and second feeding JSON through URL to the Chart processor SWF. Ok so lets write a "Hello Charts" Plugin But first I assume that you have downloaded Open flash charts from the above link and have extracted it somewhere Create a directory called hello-chart under your /wp-content/plugins folder and create a file called hello-chart.php So the final path will look like this /wp-content/plugins/hello-chart/hello-chart.php From the extracted OFC archive copy folder php-ofc-library to hello-chart folder to the path for OFC looks like this /wp-content/plugins/hello-chart/php-ofc-library Make sure that from the OFC archive you've copied open-flash-chart.swf, json2.js and swfobject.js to your hello-chart folder. I am not creating subfolders to keep things simple. So the final file system will look like this Add admin_init action as shown below to enqueue the js files [crayon-64832ee0b805b763263732/] Now lets include the open-flash-chart.php file in our plugin. [crayon-64832ee0b805f077983400/] Lets add a Navigation Menu page for an admin to view our chart. My only intention is to show you how OFC is done, there are many ways you may want to use OFC. [crayon-64832ee0b8061635985965/] Now add a function disply_hello_chart as shown below Method 1 for chart implementation [crayon-64832ee0b8062275590321/] [crayon-64832ee0b8063228237331/] [crayon-64832ee0b8064051641833/] Advertisement The above code has been taken from OFC's website. But you get the idea. Now when an administrator click on "Hello Chart" navigation then a bar chart with … [Read more...]
