Hi

Im using the following code to create checkboxes in a form. What I need, is the boxes the user checked, to remain checked after the form has been submitted. The reason for this is so that the user will not have to re-check the boxes if they would like to submit the form again. How can I do this using php code ?

PHP Code:
if ($db_found) {

    
$sql="select cname, cid from course";

    
//query the database
    
$rs=mysql_query($sql) or die($sql.">>".mysql_error());

    
//count how many records found
    
$num=mysql_num_rows($rs);

if(
$num>0){ //check if
<FORM NAME ="form1" METHOD ="POST" ACTION ="student_reg.php">
//create array loop
    
while($row=mysql_fetch_array($rs)){

        
// extract row and echo the array
        
extract($row);

    echo 
"$cname"."<Input type = 'Checkbox' Name ='chk1[]' value ='$cid'>";

}

    <
INPUT TYPE "Submit" Name "Submit1"  VALUE "Register">


    </
FORM>
}
