Code: <?php $qs=$_REQUEST['seno']; mysql_connect("localhost","root",""); mysql_select_db("test"); mysql_query("delete from emp where sno=$qs"); header("location:getrec.php"); ?> /*<script> function delrec(sno) { rv=confirm("u want to delete"); if(rv==true) { location="delete.php?seno="+sno; } } </script> */ also i want to insert values of three fields using php code. i have written the code.when i click the insert button it should get inserted into database.... below is the code for insert function..

You need to use a query to get the id of each item and use that as the value attribute of the input element. PHP: $q = mysql_query("SELECT * FROM tB"); while($d = mysql_fetch_assoc($q)) { echo "<input type=\"checkbox\" name=\"id[]\" value=\"$d['id']\" />" . $d['name']; } then use my function to delete them PHP: dbMultiDelete("id","tB","id"); PHP: function dbMultiDelete($pV,$tN,$cN) { $postVar = $_POST[$pV]; //get value of id which should be an array if($postVar)//check if the value has a value { if(is_array($postVar))// postvar has a value, lets see if its an array and if it is loop through the values else perform single delete action { //is array, loop through and perform delete $s = count($postVar); $e = 0; foreach($postVar as $v) { $Q = mysql_query("DELETE FROM $tN WHERE $cN = '".$v."'");//this code will be executed until no more indexes exist in the array. $e += mysql_affected_rows($Q); // count rows affected and use to check if all rows were deleted } $r = array('itemsToDelete' => $s,'itemsDeleted' => $e); return $r; } else { $Q = mysql_query("DELETE FROM $tN WHERE $cN = '".$postVar."'"); $e = mysql_affected_rows($Q); $r = array('itemsToDelete' => 1,'itemsDeleted' => $e); return $e; } } } doing it this way will ensure everything that is selected will be deleted and if the item is already gone the return array values can be subtracted to see how many were selected vs how many where deleted. Make sure your name attribute is followed by [] i.e HTML: <input type="checkbox" name="yourNameHere[]" /> This way the values will be grouped and sent as an array with the value attribute being the value of each index of the array.
