Integrating jQuery functionality

While there are more than a few advanced web widgets and effects that use the Spry JavaScript framework, there are thousands that use jQuery, the most popular JavaScript framework. Many WordPress widgets and plug-ins rely on jQuery, and as you'll see in the chapter using WordPress plug-ins, they are drag and drop simple to use. However, if you just want to include a little custom jQuery code, you'll need to take a few extra steps. To illustrate the process, let's draw a little attention to our Newsletter Sign Up form by making it fade in when the page first loads.

In a standard Dreamweaver page, the first step for adding jQuery functionality is to include the library, either from a self-hosted file or a content delivery network, also known as a CDM, but WordPress already includes jQuery. It's actually used in the dashboard as well as a good number of other framework scripts. All you need to do is to invoke the desired framework, or as they say in WordPress speak, enqueue. Here's one way to do it.

Let's open up our header.php file from the roux theme, and I'm going to put this code right above the WordPress function wp_head. This will go in its own PHP code block, and we'll use the WordPress function enqueue. Now I'm going to bring up code hint that we set up with our site-specific code hinting earlier so that I can make sure to spell enqueue correctly, which is not the easiest word. And here is what we want, enqueue_scripts. So I'm going to go to the second one here.

So now before I put in jQuery in the center of those parentheses, I want to be sure to get rid of the trailing S here, because really what I'm doing is just wp_enqueue_script. So, now I'll add in my quotes and put jquery, lowercase, in there. So I'll save my header.php page. Now that jQuery's all queued up, what's next? Well, next we'll add in the specific jQuery code for whatever functionality we want to set up.

The current best practice regarding JavaScript is to insert your code just before the end of the page, which in WordPress means the footer page. Now we don't want this little bit of jQuery magic we're working with to run on every page just those using the events template. So let's create a custom footer for just that page and put our jQuery code there. I'll expand the Files panel and select my footer.php page that's in the roux folder, press Command+D to duplicate it and then rename footer-copy as footer-events.

Once that's renamed, I'll open it up, collapse the Files panel, let's go into Code view it make it a little bit easier, and scroll all the way down to the bottom of the page. Now I'm going to put my script tag right above the wp_footer rule, and this is a standard script tag with a type of text/javascript, and within it is the jQuery call.

Now the syntax for this is a little bit different than your normal jQuery colon. I'll point out what is different. Typically, you start with a document.ready function envelope, and this will be about the same but just a slight tweak. So instead of starting with document.ready, we start with jQuery and then add the document.ready. So it's (document).ready and they we'll open a parentheses again, put in function and then another open parenthesis.

Now typically, this parenthesis is left empty, but to allow the code within WordPress to recognize the dollar sign syntax that we'll be using, we put it in a dollar sign. So the two differences really are just adding jQuery to the start of this line and putting a dollar sign in your parentheses following function. All right. So let's go ahead and put our first opening curly brace here, and let's put in the first of two lines. We'll put in a dollar sign so that we can identify our selector which is going to be the fieldset tag and then encase that in quotes and also parentheses and then .css because we're going to change the CSS property, and the CSS property we are going to change is the display property.

So I'll put that in quotes as well, followed by a comma and then the property we're setting it to, which is none. So basically what this is saying is when the page first loads, hide the fieldset. Now let's display it. So I'm just going to copy that first selector there, all the way up to and including the dot, and then on the next line paste it in and then we'll call a jQuery function, fadeIn, and give it a value of 2000.

So that's 2 seconds and close it all out with a semicolon, and then let's close off our curly braces as well as the parentheses and the final semicolon. Okay, that's all good. We'll save this page, footer_events.php. Now we are ready to tie footer_events.php to the events template. So I'm going to go over to my events.php page, scroll down to the bottom where we have get_footer on line 84, and rather than have the generic get_footer empty parentheses, let's add in two single quotes and put in our template name which is events.

Believe it or not, we are done, it's that simple. So I'll save the page, and let's run it through its paces and see how it looks. I'll go back over to Dreamweaver, go into Design view, and let me scroll down just a little bit so we see our form. I'll hit Refresh. And when the page loads, our Sign Up for Newsletter is not there and then it fades in. While it works in Dreamweaver, it's not quite as smooth as it will appear in the browser. So everything's working as expected.

Of course, this is just the bare minimum of what you can do with jQuery in WordPress. Keep in mind that if you want to work with other jQuery libraries, like jQuery UI, you'll need to enqueue that script as well.

Q: While trying to set up a Dreamweaver site, an error occurs that says Dreamweaver cannot resolve the dynamic files because the site definition is incorrect. What is causing this? This is using WAMP on a Windows 7 computer.
A: When setting up the site in Dreamweaver and creating a local testing server, make sure to point it to the folder in c:/wamp/www/ that is being used for the site. If using the same naming convention as shown in the videos, the server folder should be pointing to C:\wamp\www\explore_ca\ and the Web URL field should read http://localhost/explore_ca/, like the picture here:

Q: How do I set the password for WAMP Server 2?
A: The WAMP server does not include a password for MySQL when first installed. You’ll need to add a password by modifying a configuration text file and set up a password in the MySQL server.
Setting a password on the MySQL server:

  1. From the Start menu, enter CMD to open the command line interface.
  2. Switch to the bin directory of your MySQL folder, installed by WAMP. For version 5.1.36 of MySQL, for example, enter cd c:\wamp\bin\mysql\mysql5.1.36\bin
    Navigate within the WAMP folder installed on your system to find the proper path.
  3.  Enter the following: mysql -u root
  4. The command line for MySQL will open with a mysql prompt like this: mysql>
  5. Enter the following:
    SET PASSWORD for 'root'@'localhost' = PASSWORD('yourPassword');
    - replace 'yourPassword' with the password you want to use. 
  6. Close the CMD window.
Setting the password in the phpMyAdmin config file:
After you change the MySQL password you will have to edit the config.inc.php file. Here's how:
  1. In Windows Explorer, navigate to C:\wamp\apps\phpmyadmin3.2.0.1 (version number may vary). 
  2. Open the file config.inc.php in Dreamweaver or another text editor.
  3. Locate the following line:
    $cfg['Servers'][$i]['password'] = '';
  4. Enter your password between the quotes; make sure the password is the same as the one you set in the MySQL server.
  5. Save the file.
  6. From the system tray icon for WAMP, choose Restart All Services.
  7. To test, choose phpMyAdmin from the WAMP system tray icon.

Q: After creating a template following the instructions in the Chapter 5 video “Creating a page template in Dreamweaver,” I am unable to select the template. In the video, the instructor’s page shows a heading of Template, with a dropdown menu, but my version shows only a dropdown labeled “Attributes,” and the newly created template does not appear. What is causing this issue?
A: This seems to be a bug in WordPress that occurs occasionally. Although a cause has yet to be determined, a possible workaround to get the Template option to appear is switch themes. Switching to the default theme and then back again to Explore_California should reveal the Template option.
Q: While following along with the instructions in the "Setting up a MySQL password for Windows," I encountered this error: MySQL said: "#1045 – Access denied for user ‘root’@’localhost’ (using password: NO)" What is causing this error?
A: This error occurs when trying to enter the MySQL monitor with a password for a user who has not set a password yet. In that case, removing the “-u root” part should resolve the problem.
Q: While following along to the chapter 2 movie "Using dynamically related files," I get an error message that reads: "Dynamically-related files could not be resolved because the site definition is not correct for this server." What is causing this error?
A: This is a known issue with Dreamweaver, and relates to the permalink settings in the WordPress installation. If the permalink setting is set to something other than the default, like “Month & Name,” for example, Dreamweaver is unable to resolve the dynamic files, and the described error will occur. Changing the permalink setting back to Default will clear the error.
Q: I am bit confused as to my need to use MAMP with a WordPress site in Dreamweaver. If I am going to use a separate commercial hosting site as my server, do I still need to use MAMP in my WordPress site?
A: MAMP is installed to provide an easy-to-use development server capable of handling MySQL and PHP on your local computer. It's also possible to set up MySQL and PHP servers separately, but it requires many more steps and is not as "user-friendly" as the described process. Your hosting server will have MySQL/PHP enabled on their servers for the remote live setup, but that doesn't have anything to do with developing and testing pages on your own computer.
Q: I can't find the file named commevents.php in the exercise files. I need it to set up an online database in the last chapter.
A: This is a file you create yourself when you first connect to a database. Refer to the "Adding WordPress dynamic data to pages" video in Chapter 7. commevents.php should appear in the Connections folder once you establish a connection.
Q:  In "Setting up a MySQL password for Windows", I'm getting the error "#1045 - Access denied for user 'root'@'localhost'" when testing the phpMyAdmin.

If I try and re-do the steps, I get the following error "ERROR 1044 (42000): Access denied for user ''@'localhost' to database mysql'" when I try to change the password.
A: This seems to be happening because of the combination of Windows 7 and a
new version of WampServer 2.1. Here's another approach that should work
for the new combination.

Follow these steps instead of the ones using the CMD prompt. (As a bonus, they're much easier!)
  1. Left-click on the WampServer icon tray.
  2. Choose phpMyAdmin.
  3. When the phpMyAdmin page opens in your browser, click the Privileges tab found after the Engines tab.
  4. Locate the line in the User table with "root - localhost - No..." (probably the last one).
  5. Click the Edit icon (the final item in the row).
  6. Scroll down to the Change Password section.
  7. Select Password and enter your password twice. (If you're following the exercises, enter root).
  8. Click Go in the lower-right corner.
Now follow the rest of the steps in "Setting up a MySQL password for Windows" video, starting at the 4:13 mark. This is where you use a text editor to make a change in the config.inc PHP file and restart all WampServer services when you're done.
Q:  I want to setup the practice files and site on my localhost, as described; however, I already have my current WordPress site (under development) running on my localhost. How do I run two WordPress sites on my localhost?
A:  You can easily do it by setting up another site in Dreamweaver. Just copy the WordPress files to that folder as described and establish a new database via phpMyAdmin. You can set up as many WordPress sites as you need to. The author has upwards of 80 on his system, all for different clients.
Q: This course was updated on 10/23/2012. What changed?
A: The course was thoroughly revised and uses the most current versions of both programs. We added chapters on responsive design and creating a custom administration panel in WordPress, new movies about concepts and taxonomies, and extended the Spry chapter to include jQuery, among other changes. New movies are indicated by the NEW tag next to the movie name.
