Supressing printing if no value

[gordo58]

Hi,

I'm new to php so I'll probably be posting a few queries along the way.

The problem I'm having is I'm trying to print out an address in an HTML table with information taken from a database. The fields are Address1, Address2, Address3, Address4 and Postcode. Everything prints correctly but as there is no value in the Address2 field an extra comma appears after where the data would have been.

My question is, how do I stop this comma from printing if a field is empty?

<?php
include 'connect.php';

// Execute the SQL query and return records

$result = mysql_query("SELECT * FROM tablename WHERE id = 1234");

while ($row = mysql_fetch_array($result)) {
echo "<table width=\"75%%\" align=\"center\" cellpadding=\"0\" cellspacing=\"2\">\n";
echo "  <tr>\n";
echo "    <td width=\"75%\" class=\"infoname\">".$row{'Name'}." <img src=\"../images/1234.gif\" width=\"72\" height=\"20\"></td>\n";
echo "    <td width=\"25%\"  class=\"infotext\">&nbsp;</td>\n";
echo "  </tr>\n";
echo "  <tr>\n";
echo "    <td width=\"75%\" class=\"infotext\">".$row{'Address1'}.", ".$row{'Address2'}.", ".$row{'Address3'}.", ".$row{'Address4'}.",  ".$row{'Postcode'}.",</td>\n";
echo "  </tr>\n";
echo "</table>";
}
?>

Hope you can help.

i was little confused as to why you had 4 address field, but i think this might work. i haven't been able to test it.

<?php
include 'connect.php';

// Execute the SQL query and return records

$result = mysql_query("SELECT * FROM tablename WHERE id = 1234");

while ($row = mysql_fetch_assoc($result)) {
echo "<table width=\"75%%\" align=\"center\" cellpadding=\"0\" cellspacing=\"2\">\n";
echo " <tr>\n";
echo " <td width=\"75%\" class=\"infoname\">".$row['Name']." <img src=\"../images/1234.gif\" width=\"72\" height=\"20\"></td>\n";
echo " <td width=\"25%\" class=\"infotext\">&nbsp;</td>\n";
echo " </tr>\n";
echo " <tr>\n";
$i = 1;
$addr = '';
while( $i < 5 ) {
	$str   = $row["Address{$i}"];
	if ( !empty( $str ) ) {
		$addr .= "{$str},";
	}
$i++;
}
echo " <td width=\"75%\" class=\"infotext\">" . $addr . ", ".$row['Postcode'].",</td>\n";
echo " </tr>\n";
echo "</table>";
}
?>
