Issues updating record using mysqli - php

Question

I want to update/edit my user form, but when I click the "edit" button, I'm not getting the expected results. It should display the new data, but It displays the old data instead.
coding:
<?php
include"errorReporting.php";
include "conn.php";
$conn = connect();
$conndb = connectdb();
$wardID = $_REQUEST["wardID"];
$RequestName = $_REQUEST["RequestName"];
$Department = $_REQUEST["Department"];
$Position = $_REQUEST["Position"];
$Date= $_REQUEST["Date"];
$TypeOfRequest = $_REQUEST["TypeOfRequest"];
$PleaseSpecify = $_REQUEST["PleaseSpecify"];
$DateRequire = $_REQUEST["DateRequire"];
$DateReturn = $_REQUEST["DateReturn"];
mysqli_select_db($conn,"misadmin") or die ($conn->error ."\n");
$query = "select * from requestform";
$result2= $conn->query($query) or die ($conn->error ."\n");
$row_result =mysqli_fetch_assoc($result2);
mysqli_select_db($conn,"misadmin") or die ($conn->error ."\n");
$conn ->query("UPDATE requestform SET RequestName='$RequestName',Department='$Department',Position='$Position',Date='$Date',TypeOfRequest='$TypeOfRequest',PleaseSpecify='$PleaseSpecify',DateRequire='$DateRequire',DateReturn='$DateReturn' where wardID='$wardID'",$conn->affected_rows);
$result_update=mysqli_fetch_assoc($result);
header("Location:requestform3.php");
?>
output:

Answer 1

try it:
$conn ->query("UPDATE requestform SET RequestName='$RequestName',Department='$Department',Position='$Position',Date='$Date',TypeOfRequest='$TypeOfRequest',PleaseSpecify='$PleaseSpecify',DateRequire='$DateRequire',DateReturn='$DateReturn' where wardID=$wardID ");

Answer 2

in where wardID='???' Must retrieve the data before it changes. i mean "4f" not "med".
you can add a textbok in your post form :
<input type="hidden" id="original_wardID" value="<?php echo $wardID?>" />
in your php code add :
$ori_wardID=$_REQUEST['original_wardID'];
then change your sql :
UPDATE requestform SET wardID='$wardID',RequestName='$RequestName',Department='$Department',Position='$Position',Date='$Date',TypeOfRequest='$TypeOfRequest',PleaseSpecify='$PleaseSpecify',DateRequire='$DateRequire',DateReturn='$DateReturn' where wardID='$ori_wardID'

Answer 3

"UPDATE requestform SET RequestName='$RequestName',Department='$Department',Position='$Position',Date='$Date',TypeOfRequest='$TypeOfRequest',PleaseSpecify='$PleaseSpecify',DateRequire='$DateRequire',DateReturn='$DateReturn' where wardID='$wardID'"
change to
"UPDATE requestform SET RequestName='".$RequestName."',Department='".$Department."',Position='".$Position."',Date='".$Date."',TypeOfRequest='".$TypeOfRequest."',PleaseSpecify='".$PleaseSpecify."',DateRequire='".$DateRequire."',DateReturn='".$DateReturn."' where wardID=".$wardID
or like this demo code
$db_sql="select id ,uid,regdate from `newtable` where id=?";
$stmt=$mysqli->prepare($db_sql);//
$stmt->bind_param("i",$id);// i int d double s string b blob
$result = $stmt->execute();
but I guess use pdo will be better

Answer 4

You are not using if ($_SERVER['REQUEST_METHOD'] == 'POST'){//save database} or if (isset $_POST['edit']){//save database} for the edit button in order to save data when edit button is clicked.
Plus you are using Date in your UPDATE query (Date =). DATE is also as a native function used in MYSQL, you need to change it. In case you changed it to DateChanged use prepared statement it helps your code to be more readable.
if ( $_SERVER['REQUEST_METHOD'] == 'POST' )
{
$stmt = $conn->prepare("UPDATE requestform SET RequestName=?,
Department=?, Position=?, DateChanged=?, TypeOfRequest=?,
PleaseSpecify=?, DateRequire=?, DateReturn=? WHERE wardID=?");
$stmt->bind_param("sssssssss", $RequestName, $Department,
$Position, $DateChanged, $TypeOfRequest, $PleaseSpecify,
$DateRequire, $wardID);
$stmt->execute();
$stmt->close();
$conn->close();
}

i had found my answer. after i redo back my coding using the old template
here are the code.
<?php
// to connect with the database system
include "errorReporting.php";
include "conn.php";
$conn = connect();
$conndb = connectdb();
$wardID = $_REQUEST["wardID"];
$RequestName = $_REQUEST["RequestName"];
$Department = $_REQUEST["Department"];
$Position = $_REQUEST["Position"];
$DateRequest = $_REQUEST["DateRequest"];
$TypeOfRequest = $_REQUEST["TypeOfRequest"];
$PleaseSpecify = $_REQUEST["PleaseSpecify"];
$DateRequire = $_REQUEST["DateRequire"];
$DateReturn = $_REQUEST["DateReturn"];
mysqli_select_db($conn,"misadmin") or die (mysql_error()."\n");
$query = "select * from requestform" ;
$result = $conn->query($query) or die (mysql_error()."\n".$query);
$row_result=mysqli_fetch_assoc($result);
mysqli_select_db($conn,"misadmin")or die (mysql_error(). "\n");
//to update the data
$update="update requestform SET
RequestName='$RequestName' ,Department='$Department' ,Position='$Position' ,DateRequest='$DateRequest' ,TypeOfRequest='$TypeOfRequest',PleaseSpecify='$PleaseSpecify' ,DateRequire='$DateRequire' ,DateReturn='$DateReturn' where wardID='$wardID'";
$rowinsert=$conn->query($update);
header("Location:requestform3.php");
?>
thanks for those who gave the suggestions.I had learnt a lot from you all.
