checkbox arrays php

Postby virtualk » Tue Apr 09, 2013 1:13 am

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 ?

Code: Select all

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>
}

}

you can post the form to same page and can do the operation of student_reg.php in the same page so that the form will remain there.
then you can recheck the checked boxes by using the posted parameters of the checked check boxes.
