"IF" Statement
I've been trying to display other text if the row in a table is empty.
This page is coming from another script, say siteDetails.php?id=11

Here's what I have so far,


PHP Code:
 dataBase: 
  id int(11) NOT NULL auto_increment,
  name varchar(255) NOT NULL default '',
  email varchar(255) NOT NULL default '',
  urlLink varchar(100) NOT NULL default '',
  urlName varchar(255) NOT NULL default '',

// dB Connection
$connection = mysql_connect($hostType, ect...
// Query for info
$query = "SELECT * FROM $tableName WHERE id = '$id'";

$result = mysql_query($query) or die ("Error in query: $query. " . mysql_error());
$row = mysql_fetch_object($result);
if ($row)
{

// Displaying the results
User: <a href="<? echo $row->email; ?>"><? echo $row->name; ?></a>

<?
if (empty($ScrUrl)) {
    print ("No URL Provided");
} else {
    print ("Source: <a href=\" $row->ScrUrl \"> $row->ScrName </a>");
}
?>

I have also tried this...

<?
if (empty ($ScrUrl) == TRUE) {     
    print " No Url Provided";
} else {
    print " Source: <a href=\" $row->ScrUrl; \"> $row->ScrName </a> ";
}
?>

Both statements above print "No Url Provided", 
Even if there is a url and a name in those tables. 

Everything else works, with no errors.

Sorry, I got it right after I posted this...

PHP Code:
<?
if (empty ($ScrUrl) == TRUE) {     
    print " No Url Provided";
} else {
    print " Source: <a href=\" $row->ScrUrl; \"> $row->ScrName </a> ";
}
?>

I changed $ScrUrl to $row->ScrUrl , like I did on all the others.

<?
if (empty ($row->ScrUrl) == TRUE) {     
    print " No Url Provided";
} else {
    print " Source: <a href=\" $row->ScrUrl; \"> $row->ScrName </a> ";
}
?>


anyways, thanks all

I agree, nicat23
I had to stand up and do a dance, after I saw what was going on.

Well - lets rewind a little:
PHP Code:
if (empty ($row->ScrUrl) == TRUE) 

No need for any of that. To correct the above, it would be:
PHP Code:
if ( empty( $row->ScrUrl ) ) 

Now, you don't even need that - you can use a boolean check on that column:
PHP Code:
if ( ( bool )$row->ScrUrl )
{
      /* empty */
}
else
{
      /* not empty */
}

Thanks jpenn,
I'll also try that method, just for my reference.

To me, It looks more simplified.
