Form Loop

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



I'm trying to create a form with a loop. I need to append a value to a field name each time through the loop. For Instance:

while ($row = mysql_fetch_assoc($result)) {
	$x=1;
echo "<tr>"; echo "<td><input type='text' id='qty' name='quantity_' size='2' value='$row[qty]' /></td>";
	echo "</tr>";
	$x++;
}

the name value quantity needs the value of x appended to it. quantity_1, quantity_2 etc. What is the correct syntax to achieve this, especially the parsing to get it to work. I suspect the dot operator to append it but I can't get the parsing down.
