Working with WordPress functions
The initial lesson in this chapter demonstrated how you could customize the dashboard. In this lesson we'll extend the administrative customization by adding an additional sidebar widget area which will be used for inserting an advertisement, one that the client can manage without designer intervention. Customizations like these empower the client, while simultaneously freeing up the designer. Now because we are going to be modifying the sidebar code, we'll need to copy sidebar.php from the parent theme folder into the child theme folder.
So I am going to expand my Files panel and then scroll up just a little bit expand custom, select sidebar.php and copy it, close up custom, select roux, and paste that in. I'll Collapse my file. Now I am going to need to close down index.php and reopen it in order for it to recognize the new sidebar.php file. So I'll locate that in my blog site here, here is index.php, and let's discover the dynamic files, and then set it into Live view and use the Custom Filter to hone in on just the files we want work with, which in this case are style.css, sidebar.php, and functions.php, click OK.
And the next up is to transfer some assets from the exercise file into the images folder for our child theme. So I am going to finder, so I'm already pointing to folder 10_02 which is within the Chapter 10 exercise files, and I want to pick up ad_box.gif, which as you can see, is just kind of a placeholder and then also sharp_ad.png, which is an ad that we are actually going to use. So I'll select both of those and copy the files, and now let's head over to htdocs/roux_academy, and as we've done before drill down into blog/wp_content/themes/roux and then _images.
And once we're there, Command+V will paste in those images. Now we are ready to bring the code for the new sidebar widget into the sidebar.php file. To save time, I have stored both the HTML/PHP code as well as the associated CSS in the exercise files. So from Dreamweaver, let's go to File > Open and then navigate to our Desktop/Exercise Files folder, open up Chapter 10/10_02, and we want to get the advert_widget_code.php file.
So let's go into Code view, and this first group of code that you see up here starting with the div acts as a placeholder for our widget functionality. The initial div tag as an in-line style which sets the background to transparent and uses a specific image that ad_box.gif as a placeholder. Now within that div wrapper is a PHP if function that checks to see if the dynamic_sidebar function exists, and if there is also a dynamic_sidebar named home_ad_1; otherwise, it puts in another bit of code.
So let's grab that code block, and we'll head over to sidebar.php, let's go into Code view here, and I want to put my new sidebar_widget below the existing sidebar widget area, and I want to put my new sidebar widget below the existing one, so I'm going to put it right before the closing div here, and that should make the advertisement fall right below all of the other widgets, no matter how many are defined. Our advertisement is going to needs some styling, so let's go grab that bit of CSS that I have in the advert code widget, and as you can see, this just targets the class advert and sets up a specific width and height as well as some padding and margin.
So I am going to copy that and go over to our roux stylesheet, which is the first one listed here. We'll go down right in front of the phone declarations that we've been working on and paste that in. Okay, two of the constituent parts are in place. Time to bring in the real engine, the function code. Again, I've put the necessary code in an exercise file. So I'll go to File > Open, and we'll head on over to our Exercise Files/Chapter 10/10_02 and choose the widget_function_code.php file.
Now this is the code for registering a new sidebar, and it specifies the Home Ad Space 1, so let me go ahead and copy this and back to index.php, and we'll go to our roux functions file, and I am going to put it pretty much right at the top but within my PHP code block. So I'll make a little room and paste it right in. As you can see, working with functions is more than just adding a code snippet to the functions.php page. Now let's save all the related files by going to File > Save All Related Files and then we go into Design view, and I'll Refresh the page.
And once that's down, let me scroll down, and there below the last widget, which is Categories, you see a placeholder for an advertisement. Now if you squint really hard, you can see the word Advertisement written in very small type at the top there. Okay, time to move to the WordPress side of the workflow where we'll see our new widget area and put it to use. So now I am going to go to Appearance > Widgets, and where there was just Sidebar Widgets before-- and let me expand that so you see the ones that we have in place--there is now a new Home Ad Space 1 widget.
I could drag any of the existing widgets into my ad area, but none of them do exactly what I want, which is to insert an image. Luckily there's one that does, and it's very easy to set up and use. Let's go get it by going to Plugins > Add New and search for image widget. The one at the very top of the list is what we are looking for. So let's click Install Now, click OK to confirm, and after WordPress has installed it, activate the plug-in.
Now when we head back to Appearance Widgets, I have an image widget here, and I can go on drag it and drop it right into my Home Ad Space. The parameters will open up here, and we want to leave the Title blank, add a new image, and I am going to select the files from my computer, and we can get this from either place. I am going to ahead and just get it from my htdocs/_images folder where I copied in the sharp_ad.png file, click Open, and there it is.
Now we'll scroll down, leave everything else as is, and click Insert Into Widget. Now one little gotcha, this widget tends to add the file name as the default Title. You want to remove that because we don't need to have a Title for an advertisement. There is lots of other features here, we could put in a Caption, again probably not necessary. You could link to the advertiser, an excellent idea, and you probably want to open that into a new window when you do. You can see the specific Width and Height that's given and the Alignment should be at center.
Let's sharpen up the Alternate Text, no pun intended, just happens sometimes, so I'll make this Sharp Art Supplies. All right, now let's click Save, and let's see how that new ad is looking. So I'll go back and visit the site, click Refresh and scroll down, and there is our advertisement. Now that we have our single ad system in place which gives total control to the client, we are ready to take it to the next level and allow the client to interactively add multiple advertisements.

Here are the FAQs that matched your search "" :
- 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:
- From the Start menu, enter CMD to open the command line interface.
- 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.
- Enter the following: mysql -u root
- The command line for MySQL will open with a mysql prompt like this: mysql>
- Enter the following:
SET PASSWORD for 'root'@'localhost' = PASSWORD('yourPassword');
- replace 'yourPassword' with the password you want to use.
- Close the CMD window.
After you change the MySQL password you will have to edit the config.inc.php file. Here's how:
- In Windows Explorer, navigate to C:\wamp\apps\phpmyadmin188.8.131.52 (version number may vary).
- Open the file config.inc.php in Dreamweaver or another text editor.
- Locate the following line:
$cfg['Servers'][$i]['password'] = '';
- Enter your password between the quotes; make sure the password is the same as the one you set in the MySQL server.
- Save the file.
- From the system tray icon for WAMP, choose Restart All Services.
- 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!)
- Left-click on the WampServer icon tray.
- Choose phpMyAdmin.
- When the phpMyAdmin page opens in your browser, click the Privileges tab found after the Engines tab.
- Locate the line in the User table with "root - localhost - No..." (probably the last one).
- Click the Edit icon (the final item in the row).
- Scroll down to the Change Password section.
- Select Password and enter your password twice. (If you're following the exercises, enter root).
- Click Go in the lower-right corner.
- 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.
