Feedback on my code

[mrgrammar]

I have a multipart form (6 pages - I shorted the code below). Instead of writing the query over and over again for each part, I came up with a way to minimize the coding. I'd like your feedback and suggestions for improving or simplifying the code.

<?PHP

if (isset($_POST[now]))		{$now == $_POST[now];}

if (isset($now)){

	$fieldname = array();
	$fc = 0;
	$bdonorid = $_POST[donorid];

	if ($now == "start"){
		// PUT IN THE INFO FROM START
		$insdon = "INSERT INTO donors (donorid) VALUES (".$bdonorid.")";
		mysql_db_query($dbname, $insdon) or die("Error: ".mysql_error());

	}elseif ($now == "1"){
		// PUT IN THE INFO FROM STEP 1
		$fieldname[$fc] = "husband_name";	$fc = $fc + 1;
		$fieldname[$fc] = "wife_name";	$fc = $fc + 1;

	}elseif ($now == "2"){
		// PUT IN THE INFO FROM STEP 2
		$fieldname[$fc] = "husband_age";	$fc = $fc + 1;
		$fieldname[$fc] = "wife_age";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_race_caucasian";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_race_black";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_race_americanindian";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_race_asian";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_race_hispanic";	$fc = $fc + 1;

	}elseif ($now == "3"){
		// PUT IN THE INFO FROM STEP 3
		$fieldname[$fc] = "husband_medhistory_acne";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_medhistory_bleeding";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_medhistory_thyroiddisease";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_medhistory_prostratedisease";	$fc = $fc + 1;
		$fieldname[$fc] = "husband_medhistory_diabetes";	$fc = $fc + 1;

	}

	if (isset($fieldname[0])){
		$fieldct = 0;
		$fields = "";
		foreach ($fieldname as $fn){

			// SEPARATE FIELDS AND IND DATA ITEMS WITH COMMAS
			if ($fieldct > 0)	{	$fields = $fields.",";	}

			// CREATE THE STRING FOR THE FIELD UPDATES
			$fields = $fields.$fn." = '".addslashes($_POST[$fn])."'";

			// INCREMENT THE FIELD COUNT
			$fieldct = $fieldct + 1;
		}

		$updrec = "UPDATE donors SET ".$fields." WHERE donorid = ".$bdonorid;
		mysql_db_query($dbname, $updrec) or die("Error: ".mysql_error());
	}
}

?>

You can use [] to append items to an array.

$fieldname[] = "husband_name";
$fieldname[] = "wife_name"; 

Look, too, at [man]array_merge[/man].

weedpacket either has patience, had to work today or is just such a nice person id say 1st and last because i couldnt really understand much of it, please in future when posting PHP code or HTML to use either

[php][/php] for PHP and [code][/code] when using other code HTML etc.

Also if your going to do one liners

if (isset($_POST[now])) {$now == $_POST[now];} 

Why not use

$now = (isset($_POST['now']))?$_POST['now']:false;

[rehfeld]

you should also make sure you use use quotes for array indices like so

// do

$_POST['now']

// dont do

$_POST[now]

Nah, it was just that really distinctive texture. In fact, on second look I'd say that neither suggestion of mine is best. Those branches are exclusive, so

$fieldname = array(
'husband_name', 
'wife_name'
);

etc. would be quite enough.
