[SOLVED] foreach() trouble

[bluebyyou]

Heres the error I got...

Warning: Invalid argument supplied for foreach() in /home/content/r/o/c/rockywiu/html/test.php on line 47

 

I am pretty sure i am getting this error because when there are no errors then the $bad_format or $blank_array arrays dont have any info in them. what im not sure is what to do about that.

 

Heres the code..

<?php include("includes.php"); ?>
<?php include("header.php"); ?>

<?
switch ($do)
{
case "insert":
	/* Set up array of field labels */
	$label_array = array ("price" => "Price","title" => "Title","description" => "Description","email" => "E-Mail");
	foreach ($_POST as $field => $value)
	{
		/* Check for blank fields */
		if ($value == "")
		{
			/* check all except type,subtype and reply for blank fields */
			if ($field != "type" or $field != subtype or $field != "reply")
			{
				$blank_array[$field] = "blank";
			}
		}
		elseif ($field == "email")
		{
			if(!ereg(".+\@.+\..+",$_POST[$field]))
			{
				$bad_format[$field] =  "bad";
			}
		}
	}
	/* if any fields were not ok, display error message and form */
	if (@sizeof(blank_array) > 0 or @sizeof(bad_format) > 0)
	{
		if (@sizeof(blank_array) > 0)
		{
			/*display message for missing information*/
			echo "you didnt fill out one or more required fields. you must enter:<br>";
			/*display list of missing information*/
			foreach ($blank_array as $field => $value)
			{
				echo "    $label_array[$field]<br>";
			}
		}
		if (@sizeof(bad_format) > 0)
		{
			/*display message for bad information*/
			echo "One or more fields have information that appears incorrect. correct the format for:<br>";
			/*display list of bad information*/
			foreach ($bad_format as $field => $value)
			{
				echo "    $label_array[$field]<br>";
			}

		}
	exit();
	}


	$today = date("Y-m-d");
	$query = sprintf("INSERT INTO Posting (postdate,type,subtype,price,title,description,email,reply) 
                  VALUES ('%s','%s','%s','%s','%s','%s','%s','%s')",
			  $today, $_POST['type'],$_POST['subtype'],$_POST['price'],$_POST['title'],$_POST['description'],

try putting a $ sign in front of the blank_array and bad_array
