inserting and deleting in php

inserting and deleting in php to database example
i have written a code in php for inserting and deleting multiple records using check boxes."test" is the database name. "emp" is the table name
which contains the following records in my database.

Code:

empno  empname  desig
1111    raju          pilot
1112    ram          chef
1113    ramu        doctor
1114    paul         engineer
1115    ajay         player

now i want to delete one or more records and insert the records in to the above table..
i have written the below code for deleting but the table values are not displaying and i need to delete also using check box.
below is delete_multiple2.php

Code:


<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="test"; // Database name
$tbl_name="emp"; // Table name
// Connect to server and select databse.
mysql_connect($host, $username, $password)or die("cannot connect");
mysql_select_db($db_name)or die("cannot select DB");
// Check if delete button active, start this
if(isset($_POST['delete'])){
    if(sizeof($_POST['chkbx'])){
        foreach($_POST['chkbx'] AS $val){
            $sql = mysql_query("DELETE FROM $tbl_name WHERE id=".(int)$val)or die(mysql_error());
        }
    }
    // if successful redirect to delete_multiple.php

    if($sql){
        header('Location:delete_multiple2.php');//THIS WAS SAMPLE.PHP - YOU MIGHT WANT TO CHANGE IT BACK
    }
}
 $sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);
 ?>

<table width="400" border="0" cellspacing="1" cellpadding="0">
<tr>
<td><form name="form1" method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>">
<table width="400" border="0" cellpadding="3" cellspacing="1" bgcolor="#CCCCCC">
<tr>
<td bgcolor="#FFFFFF"> </td>
<td colspan="4" bgcolor="#FFFFFF"><strong>Delete multiple rows in mysql</strong> </td>
</tr>
<tr>
<td align="center" bgcolor="#FFFFFF">#</td>
<td align="center" bgcolor="#FFFFFF"><strong>EmpNo</strong></td>
<td align="center" bgcolor="#FFFFFF"><strong>EmpName</strong></td>
<td align="center" bgcolor="#FFFFFF"><strong>Desig</strong></td>
</tr>
<?php
$x = 0;
while($rows=mysql_fetch_array($result)){
$x++;
?>
    <tr>
        <td align="center" bgcolor="#FFFFFF"><input name="chkbx[]" type="checkbox" id="checkbox_<? echo $x; // you need a unique id per checkbox ?>" value="<? echo $rows['id']; ?>"></td>
        <td bgcolor="#FFFFFF"><? echo $rows['id']; ?></td>
        <td bgcolor="#FFFFFF"><? echo $rows['empno']; ?></td>
        <td bgcolor="#FFFFFF"><? echo $rows['emoname']; ?></td>
        <td bgcolor="#FFFFFF"><? echo $rows['desig']; ?></td>
    </tr>
<?php
}
?>
<tr>
<td colspan="5" align="center" bgcolor="#FFFFFF"><input name="delete" type="submit" id="delete" value="Delete"></td>
</tr>
<?
mysql_close();
?>
</table>
</form>
</td>
</tr>
</table>


also i have written for inserting records into database.
but it is not inserting.....
below is insert.php

Code:


<?php
$host="localhost"; // Host name 
$username="root"; // Mysql username 
$password=""; // Mysql password 
$db_name="test"; // Database name 
$tbl_name="emp"; // Table name

// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

$sql="SELECT * FROM $tbl_name";
$result=mysql_query($sql);

// Count table rows 
$count=mysql_num_rows($result);

<?php
while($rows=mysql_fetch_array($result))
{
?>

<tr>
<td align="center" bgcolor="#FFFFFF"><input name="checkbox[]" type="checkbox" id="checkbox[]" value="y" /></td>
<td align="center"><input name="empno[]" type="text" id="name" value="<? echo $rows['empno'];?>"></td>
<td align="center"><input name="empname[]" type="text" id="empname" value="<? echo $rows['empname'];?>"></td>
<td align="center"><input name="desig[]" type="text" id="desig" value="<? echo $rows['desig'];?>"></td>
</tr>

<?php
}
?>
<input type="submit" name="Submit" value="Submit">

<?php

// Get values from form 
$no=$_POST['empno'];
$name=$_POST['empname'];
$desig=$_POST['desig'];

// Check if button name "Submit" is active, do this 
if($checkbox){
for($i=0;$i<$count;$i++)
{
$sql1="INSERT INTO $tbl_name (empno, empname, desig)VALUES('$no[$i]', '$name[$i]', '$desig[$i]')";
$result1=mysql_query($sql1);
}
}


i want to integrate these two things so that it will be easy for inserting
and deleting any no of times..
kindly tell me how to do it....
where is my code went wrong.......

Your code looks working well ,please post me the errors you are getting , also after you delete records you have this lines of code :

Code:

    if($sql){
        header('Location:delete_multiple2.php');//THIS WAS SAMPLE.PHP - YOU MIGHT WANT TO CHANGE IT BACK
    }



it moves you to different page.
