Moving of data from old table to another table PHP MYSQL - php

Question

i have some problem on creating a delete query on my code.
the flow will be, moving data from one table to another, im placing delete codes but its not working
my code
<?php
require_once('php/dbase.php');
$query="INSERT INTO tbl_user (username, password, access_type) VALUES ('".$_POST['user']."','".$_POST['pass']."','staff')";
if($mysqli->query($query)){
$id=$mysqli->insert_id;
$query2="INSERT INTO tbl_accounts (id,fname,mname,lname,gender,designation,s_question,s_answer) VALUES (".$id.",'".$_POST['fname']."','".$_POST['mname']."','".$_POST['lname']."','".$_POST['gender']."','".$_POST['designation']."','".$_POST['s_question']."','".$_POST['s_answer']."')";
if($mysqli->query($query2)){
$error=0;
?>
<script type="text/javascript">
alert("The account has been successfuly verified");
location.href = "account_man.php";
</script>
<?php
}else{
$error=1;
$message="Error";
$data=array('error' =>$error , 'message'=>$message);
echo json_encode($data);
}
}else{
$error=1;
$message="Error";
$data=array('error' =>$error , 'message'=>$message);
echo json_encode($data);
}
?>
The old table is named "tbl_user_reco" and "tbl_accounts_reco".
Note: tbl_user_reco is auto increment
Delete Code
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "tdsw_db";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// sql to delete a record
$sql = "DELETE FROM tbl_user_reco WHERE id= '.$id.'";
$sql = "DELETE FROM tbl_accounts_reco WHERE id= '.$id.'";
if (mysqli_query($conn, $sql)) {
echo "Record deleted successfully";
} else {
echo "Error deleting record: " . mysqli_error($conn);
}
mysqli_close($conn);
}else{
$error=1;
$message="Error";
$data=array('error' =>$error , 'message'=>$message);
echo json_encode($data);
}
This is my merged Add and Delete Code and when i run it shows the "Record deleted successfully" but it never deletes anything but it adds data to the new table
<?php
require_once('php/dbase.php');
$query="INSERT INTO tbl_user (username, password, access_type) VALUES ('".$_POST['user']."','".$_POST['pass']."','staff')";
if($mysqli->query($query)){
$id=$mysqli->insert_id;
$query2="INSERT INTO tbl_accounts (id,fname,mname,lname,gender,designation,s_question,s_answer) VALUES (".$id.",'".$_POST['fname']."','".$_POST['mname']."','".$_POST['lname']."','".$_POST['gender']."','".$_POST['designation']."','".$_POST['s_question']."','".$_POST['s_answer']."')";
if($mysqli->query($query2)){
$error=0;
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "tdsw_db";
// Create connection
$conn = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
// sql to delete a record
$sql = "DELETE FROM tbl_user_reco WHERE id= '.$id.'";
$sql = "DELETE FROM tbl_accounts_reco WHERE id= '.$id.'";
if (mysqli_query($conn, $sql)) {
echo "Record deleted successfully";
} else {
echo "Error deleting record: " . mysqli_error($conn);
}
mysqli_close($conn);
}else{
$error=1;
$message="Error";
$data=array('error' =>$error , 'message'=>$message);
echo json_encode($data);
}
}else{
$error=1;
$message="Error";
$data=array('error' =>$error , 'message'=>$message);
echo json_encode($data);
}
?>

If you see this code, you are overwriting $sql, and its executing only second query,
$sql = "DELETE FROM tbl_user_reco WHERE id= '.$id.'";
$sql = "DELETE FROM tbl_accounts_reco WHERE id= '.$id.'";//$sql overwriting.
if (mysqli_query($conn, $sql)) {
