Video: Protecting page access with PHP server behaviors

Once you've created a login form for your web site, you can then protect individual pages so that only users who have logged in can view them. For this demonstration, I'll use the file explorerlist.php in the explorers folder, under the chapter 8 site root. With the file open on the screen, I'll go to the menu and choose Insert > Data Objects > User Authentication. From there, I'll choose Restrict Access To Page. On this screen, I am asked to check whether a user has already logged in.

Protecting page access with PHP server behaviors

Once you've created a login form for your web site, you can then protect individual pages so that only users who have logged in can view them. For this demonstration, I'll use the file explorerlist.php in the explorers folder, under the chapter 8 site root. With the file open on the screen, I'll go to the menu and choose Insert > Data Objects > User Authentication. From there, I'll choose Restrict Access To Page. On this screen, I am asked to check whether a user has already logged in.

You can either choose to protect based on a username and password or a username, password, and access level. I'll use the default setting, and that means that anybody who is logged in will be able to view the page. Then for users who haven't logged in, I'll indicate which page I want them to see. I'll browse, make sure I'm at the site root, go to the login folder, and choose my login form, login.php, and then I'll click OK. I'll save my changes, and I'll run the page in the browser.

And now, instead of going to the page I requested, I am sent to the Log In form. If you're working on Mac and you're having trouble previewing the file, go back to the first video in this chapter and make sure you followed the instructions for updating your database connection. It might be that you're having trouble connecting to the database. Let's take a look at the code that was generated. I'll go back to the page in Dreamweaver and look at Code View. Up at the top of the page, there is a bunch of new PHP code. Here are some of the critical pieces.

This conditional code block checks to make sure that a session has been started. The nature of a session is that it tracks a particular user, as long as they keep their browser open. Information is passed from page to page using something called a cookie. You don't need to worry about how this works; it's all handled automatically by PHP and the browser. But it is important to note that in PHP any page that you need to protect or any page that you need to put information into the session must call the session_start function.

Once that function has been called, this session associative array known as $_SESSION is created. And so this expression is set, $_SESSION returns true, if the session has started and false if it hasn't been. The rest of the code examines whether the current user has logged in, and then indicates with this variable, MM_ restrictGoTo, which page should be navigated to if the login fails. That's pretty much it.

If you want to apply this page restriction to all of your pages, you could copy this PHP code block, starting here at line 2, and going down to the end of the code block at line 46 into a separate PHP file, and then you could include that file in all of your other pages throughout the web site. I'm going to keep this demonstration focused on a single page though, so that we can see how the code that's generated by Dreamweaver works in its default state.

Now, to complete the cycle, I'll preview the page in Firefox. And now, I am going to log in with my user name and password, explorerone and password, and I'll click Submit. As long as I keep the browser open, I'll be able to navigate around throughout the web site. I can go to the Insert form and back. I can click Delete and delete a record, and I can also update data. If I close the browser though, and then restart the page, I'll see that my session has started over, and I am sent back to the Log In form.

Again, you can either protect each page individually, or you can take this generated code that to remove your places at the top of a page, move it into its own PHP file and then include it in all the pages that you want to protect. The default behavior is that any user who is logged in at all can see the protected pages, but you can also apply access levels, if you desire, to create a more granular security model.

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.
