This example only has 3 checkboxes, but the principle is still the same: <?php require_once("dbFunctions.php"); dbConnect(); if(isset($_POST['Submit'])) { $name = $_POST['txtname']; $opt1 = $_POST['checkbox']; $opt2 = $_POST['checkbox2']; $opt3 = $_POST['checkbox3']; $query="INSERT INTO alloyd (name, option1, option2, option3) VALUES ('$name', '$opt1', '$opt2', '$opt3');"; $result = dbQuery($query); echo "Results Added!"; } ?>

Hi I have a form with a series of 8 checkboxes. The user can select as many checkboxes as they wish (i.e. none or all . The values will be placed in a mysql databse. My problem is, if the user doesnt check a checkbox, the value isnt sent via POST and the error.... ERROR: UNDEFINED INDEX appears. Is there a method to have a default value, ro check whether it hasn't been checked etc? Any help appreicated, thanks. Mark

Hello I have a search engine script, which has used paging, and this works fine.  What I need is a snippet of code to display a message such as "no results found" if the query returns nothing.  I have tried several things, such as if's and using variables, but none of them work completly.  I am pretty OK with php but this has got me stuck. is there a very easy way to check is the '$row' is empty after doing the query (sample code below): $row=mysql_fetch_assoc($result); I am sorry fi this is confusing, if it is, please say! Im desperate for help! Thanks Mark
