The PHP language has been around for decades and not a lot has changed syntax-wise. And this is a brilliant intro for newbies because it teaches you how to setup a local server and install PHP from scratch.

This is crucial knowledge because building websites goes far beyond simple PHP code. Instead, you have to set up a character set manually that allows for letters, numbers, and the hyphen - , and then require that one or more matches exist.

As in the first section, your pattern must accommodate an optional set that matches the period. This is as simple as creating a set of the letters a-z and requiring between two and four total characters that are at the end of the string; you express this requirement like this: Next, you can modify saveComment to call validateEmail ; this ensures that you save only comments with valid email addresses. Inside saveComment , add a conditional statement that performs an important check.

Add these modifications by inserting the bold code into saveComment: The script in update. Something went wrong while saving the comment. In comments.

You can do this by modifying showCommentForm to check whether the session variables are set, then store for output in the form. You can add the code in bold to make showCommentForm start showing stored comments: Enter a comment with a valid email address you want to avoid the error screen for now , then click the Post Comment button to place a new comment on the blog entry.

After posting the comment, this script sends you back to the entry, where you can see the comment displayed both in the comment view as well as in the comment form.

Your users might be confused if the form stays populated after a successful post, so you need to unset the session variables after a comment is stored properly. You can do this by modifying saveComment with the code in bold: The comment should be displayed, but the form should be empty.

Now enter a comment with a bad email address, which should throw up an error. From the error screen, navigate back to the entry you were testing with; you should see that no comment was posted, but the information you entered remains in the form.

To counter this, you need to generate and display error messages when applicable; this will help the user fill out the form properly.

The saveComment method lets you store any errors generated as an error code; you can then use the showCommentForm to match an error with the appropriate error message you want to display on the form. Identifying Errors in saveComment Begin by identifying the errors that might occur. The first error is an unexpected failure of the database query.

Give this error the error code, 1. The second error occurs when the script encounters an invalid email, which you can identify with the error code 2. If necessary, you can add more error codes in the future. Also, you must unset the error session variable after a successful post to prevent the user from seeing the same error again, after the problem has been corrected.

Instead, you can make your script set a session variable with an error code and return nothing. Implement these changes by adding the code in bold to saveComment: When that happens, update. Your first task is to fix issues with saving comments; make the following modifications, shown in bold and starting at line 94, to update. Finally, insert the error message into the output for display.

Add these changes by inserting the code in bold into showCommentForm: Please try again! Try entering a bad email address to see your new error handling system in action see Figure The error message displayed when a bad email address is entered Basic Spam Prevention Unfortunately, any web form is a potential target for spammers, both human and automated.

If left unchecked, spammers can ruin a blog by flooding the comments with irrelevant links and other garbage. The spam buries legitimate comments and makes it difficult to find anything meaningful in the comment section, which can cause your users to give up on leaving or reading comments altogether. To confuse these bots, you can obfuscate the values by converting them to their HTML entities.

Generating Random Numbers The first task is to generate a math question. To keep things simple, all answers to the math question should be less than You place the logic to challenge your user in a new private method called generateChallenge , which you add to comments. Obfuscating the Values So far you have two random numbers in an array; next, you need to obfuscate the values. Obfuscation in programming3 is the practice of making code difficult to interpret.

This is generally done as a security measure. You want to obfuscate the values on the current form to make it more difficult for a spam bot to parse your form and answer the challenge question. Converting the random numbers to their ASCII 4 character code equivalents should help you baffle spam bots.

Computers can understand only numbers—every symbol is mapped to a numeric code. PHP provides a function to perform this conversion called ord. Obfuscate the numbers by adding the following code in bold to generateChallenge: The markup creates a text input field in which the user will type his answer to the challenge question.

You label the text input with an obfuscated string that you hope will confuse a spam bot when it displays this question: Add the code in bold to generateChallenge to return the markup for a challenge question: You add the challenge question by incorporating the code in bold to showCommentForm: Just below the comment text area, you can see a new input labeled with the challenge question see Figure Call this method verifyResponse. For the sake of simplicity, make 3 your new error code for an incorrect response to the challenge question.

You can make these changes by adding the code in bold to saveComment: The only thing left to do is to add an error message to correspond with error code 3, which you add in showCommentForm by inserting the code in bold: If you answer the challenge question incorrectly, the form displays an error message that explains what went wrong see Figure When clicked, this link takes a user to her Twitter5 home page and fills out her status field automatically with the title of the blog and a URL.

You use a shortened URL here because Twitter has a character limit for status updates, and blog URLs have a tendency to be fairly long. As I write this, Twitter is one of the most popular and fastest-growing services on the web.

Creating a Shortened Link with http: In the case of bit. The request string is the URL you want to shorten, as well as other information including the bit.
