For each, from post to session variables

[sehummel]

Here is what I am trying to do. I have a series of values posted as an associative array. I need to check each item for its value. Depending on its value, I have to set the correct session variable.

Here is what I have:

$accessories = $_POST['accessories'];

foreach($accessories as $key =>$value) {
	if ($value == 'HPDFO') {
		$_SESSION['hpdfo'] = 'Yes';
	} else {
		$_SESSION['hpdfo'] = 'No';
	}

	if ($value == 'Automation Interface') {
		$_SESSION['automation'] = 'Yes';
	} else {
		$_SESSION['automation'] = 'No';
	}

	if ($value == 'Downdraft Cutting Table') {
		$_SESSION['cuttingtable'] = 'Yes';
	} else {
		$_SESSION['cuttingtable'] = 'No';
	}

	if ($value == 'Rotary Fixture') {
		$_SESSION['rotary'] = 'Yes';
	} else {
		$_SESSION['rotary'] = 'No';
	}

	if ($value == 'Computer-Controlled Air Assist') {
		$_SESSION['airassist'] = 'Yes';
	} else {
		$_SESSION['airassist'] = 'No';
	}

	if ($value == 'Backsweep') {
		$_SESSION['backsweep'] = 'Yes';
	} else {
		$_SESSION['backsweep'] = 'No';
	}

	if ($value == 'Air Assist Cone') {
		$_SESSION['cone'] = 'Yes';
	} else {
		$_SESSION['cone'] = 'No';
	}

	if ($value == 'Compressed Air Source') {
		$_SESSION['compressed'] = 'Yes';
	} else {
		$_SESSION['compressed'] = 'No';
	}

	if ($value == 'Refridgerated Air Kit') {
		$_SESSION['refridgerated'] = 'Yes';
	} else {
		$_SESSION['refridgerated'] = 'No';
	}

	if ($value == 'Desiccant Air Kit') {
		$_SESSION['dessicant'] = 'Yes';
	} else {
		$_SESSION['dessicant'] = 'No';
	}

	if ($value == 'Traveling Exhaust') {
		$_SESSION['exhaust'] = 'Yes';
	} else {
		$_SESSION['exhaust'] = 'No';
	}
}

When I run this, only the last item in the array is set to yes, even though all items in the array should have a session variable equal to 'Yes'. Can someone please help me? Also, is there a cleaner way to do this with a switch statement?

Welcome to PHPBuilder!

When posting PHP code, please use the board's [noparse]

[/noparse] bbcode tags as they make your code much easier to read and analyze.

Now, as for your issue...

First check what values are getting passed in; do a [man]print_r/man on $accessories to see what it looks like.

I don't know about a switch() statement, but I'd probably use an array, e.g.:

$entities = array(
    // syntax is (session array key) => (corresponding POST'd value)
    'hpdfo' => 'HPDFO',
    'automation' => 'Automation Interface',
    // etc.
);

foreach($entities as $key => $value) {
    $_SESSION[$key] = (array_search($value, $_POST['accessories']) !== FALSE ? 'Yes' : 'No');
}

OK. The next step is I have to take the session variables and output them in an email. Sounds simple enough, right? Here's the problem I'm running into.

There are like ten accessories. If the user chooses items 2,4,5 and 8, then 2 is the first item in the array. If he chooses, 4,5,7,9 and 10, then 4 is the first item in the array. I need to be able to assign all ten items to either a Yes or a No, regardless of what's in the array. Since the variables only exist if they are selected in the form and then put in the array, how do I account for all ten even if there are only a few in the array? And the first one will almost always be different. How do I map a partial array to the full array, in other words?

Use [man]isset/man or [man]array_search/man to see if a particular key or value (respectively) in an array exists.
