Create a Web form to help in creating Jumble puzzles.

Create a form that has four input fields named Word1, Word2, Word3, and Word4, as well as Reset and Submit buttons. Create a form processing script that verifies that all four words are entered, that all of them contain only letters, and that all four are between 4 and 7 characters long. Once all of the words have been verified as correct, use the strtoupper() and str_shuffle() functions to produce four jumbled sets of letters.

To create the Jumble Maker form:

1. Create a new document in your text editor. Type the declaration, element, header information, and element. The page title should be "Jumble Maker, add to element.

2. Add the following HTML form tags in the body of the document:

Word 1:

Word 2:

Word 3:

Word 4:

3. Save the document as JumbleMaker.html

4. Create a new document in your text editor. Type the declaration, element, header information, and element. The title of the page should be Jumble Maker, add to the element.

5. Add the opening and closing tags for the PHP script section in the body of the document:

6. Create a function called displayError(). This function displays the error message, and takes two parameters: $fieldName, which is the name of the field as it appears on the Web form; and $errorMsg, which describes the error for the user. There is no return value for this function.

7. Create a second function called validateWord() below the displayError() function. This function takes two parameters. The first parameter, $data, is a string to be validated. The second parameter, $fieldName, is the name of the form field. The function returns the $data parameter after it has been cleaned up. After validating the user input, use the built-in PHP function strtoupper() (Links to an external site.) and str_shuffle (Links to an external site.)() to change all letters to uppercase and shuffle the letters.

8. Immediately after the validateWord() function, declare and initialize a new variable called $errorCount and a new array called $words[] as follows:

$errorCount = 0;

$words = array();

9. Add assignment statements for the $words array variable to receive the output of the validateWord() function for each form field:

$words[] = validateWord($_POST['Word1'], "Word 1");

$words[] = validateWord($_POST['Word2'], "Word 2");

$words[] = validateWord($_POST['Word3'], "Word 3");

$words[] = validateWord($_POST['Word4'], "Word 4");

10. Add a conditional statement immediately after the values of $words have been assigned. This statement will display the total number of errors found or the shuffled words if there were no errors.

if ($errorCount>0)

echo "Please use the \"Back\" button to re-enter the data.
";

else {

$wordnum = 0;

foreach ($words as $word)

echo "Word ".++$wordnum.": $word
";

}

11. Save the document as process_JumbleMaker.php.
