[Review And Pursue]

I think I had moment of clarity this morning! After re-reading the paragraph about elseif I presume elseif isn't classed as a nested conditional - rather adding a conditional to an existing one.

 

Anyway I managed it with the following code.

if (isset($_POST['gender']) && ($_POST['gender'] == 'M')) {
		$greeting = '<p><b>Good day, Sir!<b></p>';
	} elseif ((isset($_POST['gender']) && ($_POST['gender'] == 'F')) {
		$greeting = '<p><b>Good day, Madam!<b></p>';
	} else {
		$gender = NULL;
		echo '<p class="error">Gender should be either "M" or "F"!</p>';
}

Many thanks Larry,

 

I'm afraid to say, I'm still stumped with this, at least that is if i've understood it correctly- I'm reading it as using only one conditional and no nested conditionals. 

 

With one conditional I can only work out how to account for 2 eventualities - either gender being M or F.

if (isset($_REQUEST['gender']) && ($_REQUEST['gender'] == 'M')) {
	$greeting = '<p><b>Good day, Sir!<b></p>';
} else {
	$greeting = '<p><b>Good day, Madam!<b></p>';
	}

I understand this no good as it does not account for checking isset and setting gender = NULL if the user hasn't selected M or F

Hi folks

 

And thanks Larry for a great book, its quite inspiring. I'm new to programming, I know my HTML and CSS but that's it. I've been following your book and I'm up to Chapter 2 -  Review and Pursue and stuck on the third question, sorry if this has been covered already.

 

Rewrite the gender conditional in handle_form.php (Script2.4) as one conditional instad of two nested ones, Hint: you'll need to use the AND operator.

 

 

 

The code in question is

if (isset($_REQUEST['gender'])) {
 $gender = $_REQUEST['gender'];
 if ($gender == 'M') {
  $greeting = '<p><b>Good day, Sir!<b></p>';
 } elseif ($gender == 'F') {
  $greeting = '<p><b>Good day, Madam!<b></p>';
 } else {
  $gender = NULL;
  echo '<p class="error">Gender should be either "M" or "F"!</p>';
} 

I've been stuck all day, I have gone away and come back again and I'm still drawing a blank.

 

Any help would be really appreciated, thanks.
