Page rendering problem

witham · February 23, 2008

I would really appreciate a fresh pair of eyes looking at this code as it will not render properly it just displays the combobox at the bottom of the page. I have stared and stared had a break and stared and stared again but I cannot see the problem. I know it is something stupidly simply but "not seeing the wood for trees" springs to mind.

<?

//check the $ProdName variable to see if it has data if not send the user back to the entry page
// this has to be done before any output

$ProdName = $_GET['ProdName'];
$ProdEquiv = $_GET['ProdEquiv'];
$Manufacturer = $_GET['Manufacturer'];
$ProdNar = $_GET['ProdNar'];
$Category = $_GET['Category'];


if (empty($ProdName)){  
header("Location: addprod.php"); 
die ("opps");  
}

if (empty($ProdEquiv)){  
header("Location: addprod.php"); 
die ("opps");  
}


$dbuser  = 'test';		// your database server user name
$dbhost  = 'localhost';		// name of the sql server
$dbpass  = '';		// your database server password
$dbname  = 'weld';		// the name of the database to connect to 

// use a compare statement to check for duplicates

$sqlCOMPARE	= "SELECT * from prodname where '$ProdName' = proddesc;";


// the sql query to insert data into the prodname table


$sqlINSERT	= "INSERT into prodname values
	  (null, '$Manufacturer', '$Category', '$ProdName', '$ProdNar', '$ProdEquiv');";

$sqlINSERT	= strtoupper($sqlINSERT);


//use to display the desired data $sqlSELECT

$sqlSELECT	= "SELECT MANNAME, prodtype, proddesc, prodnar, prodequiv 
	FROM man, produse, prodname where manno = manid
	and manid = '$Manufacturer'
	and useid = '$Category' 		   
	and prodid = useid
                		and manno = MANID
	and useid = USEID
	order by MANNAME;";

// mysql_connect connects to the database server and returns a link to the the resource
$dblink = @mysql_connect("$dbhost","$dbuser","$dbpass") 
or die("<p><b>Could not connect to database server: ($dbhost)</b></p>\n");

// mysql_select_db selects a database to use on the database server pointers to by $dblink
// the @ sign before the command supresses any error messages
@mysql_select_db ($dbname , $dblink)
or die ("<p><b>Could not connect to database ($dbname)</b></p>\n");


// now execute the next query to determine if a duplicate has been entered and use
// an if statement to return the user to the entry page if this is true


$result  = mysql_query($sqlCOMPARE, $dblink)
or die("<p>Error Processing Query</p><hr /><p>".mysql_error()."</p>\n");


if (  mysql_num_rows($result) > 0  ){  
header("Location: alreadyin.php");  
die ("opps");  

// now execute the next query to update the database table


$result  = mysql_query($sqlINSERT, $dblink)
or die("<p>Error Processing Query</p><hr /><p>".mysql_error()."</p>\n");

// now execute the next query to display these results

$result  = mysql_query($sqlSELECT, $dblink)
or die("<p>Error Processing Query</p><hr /><p>".mysql_error()."</p>\n");

?>

the ...

while ($row = mysql_fetch_array ($result))

doesn't have a beginning bracket

fooDigi · February 23, 2008

are errors turned on for your server?

fooDigi · February 23, 2008

i see a opening bracket on line 72, and do not see any closing until line 131, may be an issue.

witham · February 23, 2008

Thanks very much for the reply can I ask what you mean by the opening bracket, still can't see it (sorry)??

I don't know if errors are turned on how would I check this please?

Could you tell me why the opening and closing brackets may be an issue?

witham · February 24, 2008

Thanks for the pointers for some really weird reason notepad (which I was using to edit the page source) wasn't showing the {} brackets. This is why I was a little vague and confused by the previous post!!

All sorted now thanks again!!
