Another question about functions...

[Jason Pruim <japruim@xxxxxxxxxx>]

HI everyone,

I think I'm getting closer to understanding functions, but I'm  
blanking on how to fix a problem that I have... I am attempting to  
export a database to excel, which was working before converting the  
code into a function.

What's happening is, I have the code set and it downloads the file  
into excel, but it doesn't have the database fields in it, rather a  
copy of the entire webpage which it trys to put into excel. Below is  
the code that I am using in my function to export the records:

<?PHP
	function excelexportfunc($select, $sortOrder, $exportdate) {
		
		$export = mysql_query($select);
		$fields = mysql_num_fields($export);
		
		for ($i = 0; $i < $fields; $i++) {
			$header .= mysql_field_name($export, $i) . "\t";
		}
		
		while($row = mysql_fetch_row($export)) {
			$line = '';
			foreach($row as $value) {
				if ((!isset($value)) or ($value == "")) {
					$value = "\t";
				}
				else
				{
					$value = str_replace('"', '""', $value);
					$value = '"' . $value . '"' . "\t";
				}	
				$line .= $value;
			}
			$data .= trim($line). "\n";
		}
		$data = str_replace("\r", "", $data);
		
		if ($data =="") {
			$data ="\n(0) Records Found!\n";
		}
		
		header("Content-type: application/vnd.ms-excel");
		header("Content-Disposition: attachment; filename=Export.". 
$exportdate.".xls");
		header("Pragma: no-cache");
		header("Expires: 0");
		
		
		
		print "$header\n$data";
	
	}

?>

I am calling the function like so: "excelexportfunc($select,  
$sortOrder, $exportdate);"

the $select is specified in an IF statement on the calling page like so:

	if($exportoption =="all"){
		$sortOrder= $_SESSION['order'];
		$search = "";
		$select = "SELECT * FROM ".$table." order by ".$sortOrder."";

	}else{

		$sortOrder = $_SESSION['order'];
		$search = $_SESSION['search'];
		$select = "SELECT * FROM ".$table." WHERE FName like '%".$search."%'  
or LName like '%".$search."%' or Add1 like '%".$search."%' or Add2  
like '%".$search."%' or City like '%".$search."%' or State like '%". 
$search."%' or Zip like '%".$search."%' or XCode like '%".$search."%'  
order by ".$sortOrder."";
	}

If anyone has any ideas I would love to hear about them. Hopefully  
it's just a simple "." in the wrong place! :)
