[Chapter 6 - Pursue]

Here is what I did for Pursue 4:

 

//Create some css styles

 

.red {color:red;}

.yellow {color:yellow;}

.green {color:green;}

.blue {color:blue;}

 

//Alter the switch statement so that each case assigns values to some new variables, and then concatenates them to a new variable, along with some html to apply the css class to the print output at the end

 

//Validate the color

switch ($_POST['color']) {

case 'red':

$color_type = 'primary';

$color_selected ='red';

$css_class = '<span class="red">' . "$color_selected" . '</span>'. ',';

break;

case 'yellow':

$color_type = 'primary';

$color_selected ='yellow';

$css_class = '<span class="yellow">' . "$color_selected" . '</span>' . ',';

break;

case 'blue':

$color_type = 'primary';

$color_selected ='blue';

$css_class = '<span class="blue">' . "$color_selected" . '</span>' . ',';

break;

case 'green':

$color_type = 'secondary';

$color_selected ='green';

$css_class = '<span class="green">' . "$color_selected" . '</span>'. ',';

break;

default:

print '<p class="error">Please select your favourite colour.</p>'. ',';

$okay = FALSE;

break;

} //end of switch

 

//Then alter the print output to include the new variable

 

//If there are no errors, print a success message:

if ($okay) {

print '<p>You have been successfully registered (but not really).</p>';

print "<p>You will turn $age this year";

print "<p>Your selected color, $css_class is a $color_type color.</p>";

}

 

 

I concatenated a comma onto the end of the $css_class variable cos I am a punctuation nerd (I even worried whether to put it inside or outside the span!).

 

This seems to work well, but I would be grateful for any comments.
