How To Change “Enter Title Here” Text In WordPress ?

WordPress displays “Enter title here” placeholder text in the title field on the post screen where you create new posts. When we create custom post types, there is no default parameter to change this text. 

here’s a simple snippet which allows you to change “Enter title here” text in WordPress posts screen and custom post types’ screen.

Just drop the following snippet to your current theme’s functions.php file:

function change_title_text( $title ){

     $screen = get_current_screen();

     if  ( 'movie' == $screen->post_type ) {

          $title = 'Enter movie name with release year';

     }

     return $title;

}

add_filter( 'enter_title_here', 'change_title_text' );

That’s all!

Difference Between Filter and Action Hooks?

Action Hooks

Actions Hooks are intended for use when WordPress core or some plugin or theme is giving you the opportunity to insert your code at a certain point and do one or more of the following:

1. Use echo to inject some HTML or other content into the response buffer,
2. Modify global variable state for one or more variables, and/or
3. Modify the parameters passed to your hook function (assuming the hook was called by do_action_ref_array() instead of do_action() since the latter does not support passing variables by-reference.)

Filter Hooks

Filter Hooks behave very similar to Action Hooks but their intended use is to receive a value and potentially return a modified version of the value. A filter hook could also be used just like an Action Hook i.e. to modify a global variable or generate some HTML, assuming that's what you need to do when the hook is called. One thing that is very important about Filter Hooks that you don't need to worry about with Action Hooks is that the person using a Filter Hook must return (a modified version of) the first parameter it was passed. A common newbie mistake is to forget to return that value!

Using Additional Parameters to Provide Context in Filter Hooks

As an aside I felt that Filter Hooks were hobbled in earlier versions of WordPress because they would receive only one parameter; i.e they would get a value to modify but no 2nd or 3rd parameters to provide any context. Lately, and positively however, it seems the WordPress core team has joyously (for me) been adding extra parameters to Filter Hooks so that you can discover more context. A good example is the posts_where hook; I believe a few versions back it only accepted one parameter being the current query's "where" class SQL but now it accepts both the where clause and a reference to current instance of the WP_Query class that is invoking the hook.

So what's the Real Difference?

In reality Filter Hooks are pretty much a superset of Action Hooks. The former can do anything the latter can do and a bit more albeit the developer doesn't have the responsibility to return a value with the Action Hook that he or she does with the Filter Hook.

Giving Guidance and Telegraphing Intent

But that's probably not what is important. I think what is important is that by a developer choosing to use an Action Hook vs. a Filter Hook or vice versa they are telegraphing their intent and thus giving guidance to the themer or plugin developer who might be using the hook. In essence they are saying either "I'm going to call you, do whatever you need to do" OR "I've going to pass you this value to modify but be sure that you pass it back."

In Short, if you look at the do_action() core function, it's very similar to the apply_filters() core function, with one very key difference: it does not return a value.

So what does this mean? actions are like filters, except an action does not return a value, so you cannot modify data. It shows that it was simple to create the WordPress' action mechanism by simply copying the filter mechanism, and not returning a value. Basically, all you can do with an action is simply execute a function without modifying some value.

EasyRotator promises that users “beautiful, responsive photo rotators and sliders to your WordPress site in seconds,” but it actually takes a bit of setting up. First you’ve got to install Flash software to create your slides – or rotators – on your local machine, which I admit I found annoying. Then you can create a new rotator from within the page or post editor. You can also use shortcode to insert a rotator in your site, or add a rotator to your theme using a function call.
After going to the trouble of installing the Flash program, it didn’t work when I tried to set up a basic slider from the Post Editor. After a bit of digging around, I discovered this plugin doesn’t work with Safari/Chrome.

Soliloquy is one of the more well-known sliders out there and for good reason – it’s simple to set up, you don’t need to download flash software to create and upload sliders or mess around with the settings. It just works.
After you’ve added your images, select your slider size, slider speed and hit “publish.” Then you’ll need to copy the resulting shortcode onto any page or post where you want the slider displayed.
While this is a lite version, it still comes with enough features to make it worth trying out.

Beginner Tips For Getting Started with WordPress Development

One of the advantages that's often associated with building for WordPress is its low barrier to entry, and although this isn't altogether false, it also makes it intimidating for anyone who is looking to truly get started in WordPress and struggled with knowing how - or where - to get started.
In fact, we're often asked various tips, ideas, and practical things that new developers can do in order to get their feet wet WordPress when they're just getting started. In an attempt to provide a reference for this often-asked question, I thought it would be worth drafting up a few points worth sharing the next time that this question comes up.
With that said, here are five suggestions that I recommend (in no particular order):

1. Don't Start Too Big!

One of the number one things that I - along with peer WordPress developers are asked - are how to do certain complex tasks right from the beginning. For example: How do I introduce frontend editing into WordPress?
This answer to this particular question can get complex very quickly.
For example, this assumes that you're comfortable with the TinyMCE editor, the JavaScript and CSS that's included  with it, PHP necessary to post back to the server and to properly handle the data that's being sent back and forth between the server and the client, the APIs necessary to handle revisions, serialization, validation, and more.
It's a lot, isn't it?
To that end, I always recommend that new developers begin with something small in mind, then grow their idea from there. When doing that, natural learning is bound to occur and you'll learn the things necessary that will allow you to accomplish more complex tasks.

2. Study Existing Code

This is something that developers - regardless of their level of skill - hear often. We're told to read other people's code, read other people's books, and follow along development with other projects.
And because it's applicable to developers of all skill levels, it's applicable to beginners, as well.
The nice thing is that, in the case of WordPress, the source code and all associated projects are open source, and thanks to websites such as GitHub, it's relatively easy to find WordPress and associated projects available for study.
The challenge with doing this, though, is knowing where to start, right? I mean, it's difficult to simply just into a function and begin tracing it's execution. So how do we actually start with something and then work forward?
There are a number of strategies for doing this, one of which I've found to be relatively powerful regardless of the feature that you're dealing with: Pick one aspect of WordPress, say the login screen, and look for part of the code in the WordPress source.
This is easy to do: After all, we have the markup visible in our browsers and the strings visible on the screen. Simply doing a "Find" in the WordPress source code will get you started somewhere along the path.
Next, trace the code that you see. Set breakpoints to debug as data is passing through it, try changing it to see if you can bend it to do something different than what it normally does.
Typically, breaking something and restoring its functionality is a fantastic way to grok how something works so that you can more easily understand how it's designed, how to implement something similar in the future, and/or how to take advantage of the relevant APIs.

3. Understand The Coding Standards

You've likely read it here on Tuts+ before, and this isn't the last time that you'll read it again: One of the most important things that you can do as a WordPress developer is to understand the WordPress Coding Standards.
After all, the purpose of coding standards is in place to make sure that the code that's being written more or less looks the same regardless of who has written it.
Some people abide by the standards, some do not. If you opt not to do so - and that is a prerogative that the developer has - then so be it; however, if you opt to do so, then you're going to be writing code that's more easily readable by those who follow the standards, build products, and so on on top of WordPress.
The thing is, there are standards for PHP, JavaScript, HTML, and CSS. It's a lot to learn, but it's worth it. The code you write will read better, and will be easier to follow by those in the economy that are constantly working to work on WordPress or work on other things for WordPress.

4. Meetups and WordCamps

This particular pointer is one that I don't believe we talk up enough: Meetups are fantastic and are so for a number of reasons.

1. You get to meet like-minded people who are curious, interested, and passionate about the same platform you are.
2. You have the opportunity to learn from people who are further down the line and able to work, and thus teach, on more extensive topics that you are.
3. You have the ability to practice your speaking skills in front of other people should you opt to present to them.
4. You have the ability to get help with your project, your code, or any other questions that you have.

And this isn't just left to meetups in the local area. WordCamps are fantastic resources for anyone who is interested in anything from just getting into blogging and getting WordPress setup to those who are looking to build an entire business around the application.
In short: Don't forget to get out of the house and interact with those in your "offline community" just as much as you do (well, at least to some degree ;) as your "online community."

5. Read Blogs

Yes - this is yet another tip about reading. As far as blogs are concerned, there has never been a better time to be a part of the WordPress economy.
Right now, there are a number of different how-to sites, news sites, tutorial sites, developer sites, designer sites, and so on all of which offer a valuable, unique perspective on exactly what it involves and what it requires in order to be a WordPress developer.
Spend the time finding and reading the blogs that are most interesting to you. On top of that, if they offer code, try to trace it and understand it. Drop it in your IDE and work on improving it, adding something to it, changing it, and so on.
Hop into a discussion in the comments or chat with the authors via email about the code they've shared. Even if you don't feel like participating in the discussion, at least lurk in the comments and track along with it. You can learn a lot just by following the conversation of other people.

But There's Always More

Honestly, these are just five quick tips to help you get started.
If you're really up for jumping into the deep end of the pool, then I also highly recommend following Trac and the associated emails that go out. It really keeps you in the loop as to what's going on in core, as well as what's happening with some of the other peripheral features of WordPress.
There are plenty more and I've love for you guys to voice your own suggestions in the comments so that we have a healthy collection of tips for our fellow readers - beginners or not.
So have at it: What are your suggestions?
