Video: Displaying data with repeating regions

Once you've defined a recordset in a PHP page, you can then display the data in a number of ways. For this demonstration, I'll use a file named tours.php. This file already has a recordset defined. If you look at the file in Code View, you'll see all the PHP code for lines 1 through 39. You can also go to the Bindings panel and find the recordset there, and double-click it open it. This is a simple recordset, so it's best viewed in that version of the recordset builder.

Displaying data with repeating regions

Once you've defined a recordset in a PHP page, you can then display the data in a number of ways. For this demonstration, I'll use a file named tours.php. This file already has a recordset defined. If you look at the file in Code View, you'll see all the PHP code for lines 1 through 39. You can also go to the Bindings panel and find the recordset there, and double-click it open it. This is a simple recordset, so it's best viewed in that version of the recordset builder.

If you want to make any changes to the recordset, you can do so either from here or by manually modifying the SQL code in the PHP page. Now I'm going to preview the page in an external browser, and I'll show you that right now we're not actually using the data in the page. The page has all static HTML, including one detailed instance of a tour package, named Backpac cal. I'll go back to the page in Dreamweaver and look at the page in Design View.

I'll scroll down to that section, I'll select the title in the package, and then go back to Code View and show you that all the information about this tour is hard-coded. We want to replace this information with repeating data from the packages recordset. Here's how I'll do it. I'll go back to Design View, and I'll start with the title element. I'll select that value, and then I'll go to the Bindings panel. I'll open the recordset, and Dreamweaver shows me the three columns that are being returned in the recordset.

I'll click on the packageTitle, and I'll drag it into the place, dropping it on top of this selected static text. That replaces the static text with some PHP code that outputs the packageTitle. With that text selected, I'll go back to Code View and show you that the PHP output looks like this: php echo, then the name of the recordset, and then the name of the column as a string.

I'll do the same thing for the package description. I'll go to Design View, I'll select the text for the package description, I'll go to the Bindings panel, and drag the packageDescription column on top of the selected text. Then I'll go back to Code View and show you the exact same sort of code here. You can do the same thing in Code View. For example, the image source is currently set to a hard-coded image file name, but we have that information also in the recordset.

I'll select the name of the file, but not the location in which the file is stored. Then I'll go to the Bindings panel, and I'll drag the packageGraphic column on top of the selected text. That replaces the hard-coded graphic file name with the dynamic file name from the recordset. I'll do something very similar in the alt value for the current image. That's also set to the title of the package, so I'll select it, I'll go to the Bindings panel and drag in the packageTitle on top of the selected text.

Now let's take a look at all of the generated code. The tour description is using four dynamic values, the packageTitle used twice, both in the heading 2 and in the alt value for the image. Then the actual name of the image is being drawn from the database here, and the description is being drawn from the database right here. I'll save the changes, and then I'll look at the page in Live View. I'll update the copy of the file on the testing server when prompted, then look at Design View, and I'll see the result.

The output looks exactly the same as it did before, but now it's dynamic. The data is being drawn from the database at runtime. Right now, I'm only displaying one record. I'm going to change this now to repeating records, so that I see one instance of this package information for each row in the recordset. I'll exit Live View, and then in Design View, I'll locate the package information. I'll click anywhere inside the package information, and then in the tag selector, I'll choose tourDescription, the div tag that wraps all that information.

Now, I'd like to make that div tag repeat, once for each row. I can do that either from the menu or from the Insert panel. I've been using the Insert panel a lot, so this time I'll go through the menu. I'll choose Insert > Data Objects > Repeat Region. I'll choose the only recordset in this file, rsPackages, and I'll choose All records, rather than 10 records at a Time, and click OK. That div tag is now displayed with a visual aid showing the word "Repeat." That means that we're repeating the div tag once for each row in the selected recordset.

I'll look at the page in Live View again. If prompted, I'll say yes, I want to save my changes, and then I'll update the file on the testing server, scroll down, and show you that now I'm displaying all the data for the selected table. There are nine rows in this selected table, and therefore nine instances of the selected div tag in the repeating region. So that's how you can dynamically output data from a recordset, using the Dreamweaver repeating region architecture.

You replace the literal values in your HTML with dynamic values from your recordset and then define the entire div tag containing the data as a repeating region, and the HTML is generated at runtime by PHP and MySQL.

Q: The Bindings panel is disabled, and I can't create new queries or form variables in the current PHP file. How can I correct this problem?
A: This indicates that the file you have open isn't a part of your current site. For example, you might have opened a file from one site, then switched sites and tried to continue working on the same file. Try closing all files, then opening the file you want to work on from the Files panel. This ensures that the current file and site are in sync.
Q: I'm having trouble getting code hinting to work on Mac OS X. Are there know issues that could be causing the issues?
A: There might be an issue with your code hinting configuration. Make sure the folders you designated in the code hinting config screen match the disk location where you copied the Zend Framework files. You should have a file named dw_php_codehinting.config in your site root folder after setting up your code hinting configuration. Assuming you copied the Zend Framework files to a folder on your Mac named /phpincludes, the contents of the file might be: "/Volumes/Macintosh HD/phpincludes/ZendFramework/library/Zend/Date" EXTENSIONS(.php) "/Volumes/Macintosh HD/phpincludes/ZendFramework/library/Zend" EXTENSIONS(.php).  The exact path will differ depending on your hard disk name and the folder to which you copied Zend Framework. For subsequent exercises in the video series, the sample files provided with the course have the configuration for Windows as demonstrated in the videos. Once you get code hinting working in one exercise, you can copy the working dw_php_codehinting.config file from the current site folder into the new site folder.
Q: I’m following along in the video "Configuring a PHP testing server." When I go to preview the index.htm or .php files, I don't get the Dependent Files dialog box, and I get the page in my browser with just the HTML and no styling. The index file gets copied to the proper folder, but none of the dependent files are getting copied over. How can I resolve this issue?
A: If you are experiencing this problem, check your settings in Dreamweaver. The prompts for putting files onto the server have most likely been turned off. Follow these steps: 1) On Windows, select Edit > Preferences. 2) In the Preferences dialog, select the Site category. 3) Make sure your options for Dependent Files (prompt on get/check out, and prompt on put/check in) are selected. 4) Make sure your Put and Move options are selected (located at the bottom of the screen). 5) Then try previewing the file again. The dialogs should appear.
Q: I am having a problem with the "Handling form submission with PHP" video in Chapter 6. When I create a form variable "firstname" in the the Binding panel, in the Simpleform2.php file, I don't see the new variable in the list afterwards. It's as if the panel is disabled. What's going on?
A: Some users have reported that this problem can be corrected by deleting a file named  ".mno" from the site folder's _notes subfolder. The file is hidden, so you won't see it in Finder on Mac or Explorer on Windows. Note that there might be many files in the _notes subfolder with the .mno extension, but you only need to delete the file with no name and just the extension.

Follow these steps to delete the file:

Windows:
Open a command window
Switch to the site folder
Type these commands:

cd _notes
attrib -H .mno (this removes the hidden flag from the file)
del .mno (this deletes the file)

Mac OS X:
Open Terminal
Switch to the site folder
Type:
cd _notes
ls -a .mno (if the file is there, this command will show it)
rm .mno (this deletes the file)
Q: I want to use the Zend Framework in my PHP site, but my internet service provider (ISP) doesn't let me modify the php.ini file to include the files as taught in the course. What can I do?
A: If your host doesn't let you make changes to your php.ini file, you can include the Zend Framework with one of these strategies:

  • Copy the Zend Framework to the folder containing your web site files. In your PHP pages, your 'include' command can refer to the appropriate files with relative directory addressing:

 <?php include('../ZendFramework/library/Zend/Date.php'); ?

  •  If your shared host provides a special directory to contain your web files (for example, it might be named 'www' or 'web'), then you can add the Zend Framework files to your root folder as a sibling to the web folder. You'll need to find out the physical folder name; PHP's $_SERVER['DOCUMENT_ROOT'] variable can help you find this:

 <?php echo $_SERVER['DOCUMENT_ROOT']; ?

You can then programmatically modify the include_path variable at runtime with the set_include_path() function. For example, if your physical root folder is /home/myroot, the code might look like this:

<?php
set_include_path('.' . PATH_SEPARATOR .
'/home/myroot/ZendFramework/library/Zend');
include('Date.php');
?
Q: This course was updated on 6/12/2012. What changed?
A: This course was updated to show the minor UI differences between Dreamweaver CS5 and CS6, especially the change from separate Live Code/Live View buttons to a single Live button.
Q: phpMyAdmin is not opening properly in the second lesson in Chapter 4, "Creating a MySQL database in phpMyAdmin." The error message says:

#2002 - The server is not responding (or the local MySQL server's socket is
 not correctly configured)
A: The error indicates that there's an incorrect reference to the MySQL 'sockets' file. This is set automatically during WampServer installation, but if you've previously installed other copies of MySQL there can be some leftover conflicts (even if you've uninstalled the other copies).

Check your system for duplicate copies of the file 'my.ini' - it's a MySQL configuration file that might have been left around from a previous installation. The most likely folder in which to look is c:\windows\System32, but it could also be elsewhere. If you find any such files that aren't in the c:\wamp directory structure, rename or delete them, then reboot your system.

If that isn't the issue, you'll need to start from scratch: back up your working files from c:\wamp\www, then uninstall WampServer, delete the c:\wamp folder completely, and reboot and reinstall. Test phpMyAdmin immediately after installation. Then, if it stops working along the way you'll have better information about what steps might have cause the issue.
