This question already has an answer here:
I'm trying to do the update function in php with a mysql database connected. I put the codes for update in a file called parcelEdit.php. Here's my code for parcelEdit.php
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Updating Parcel Details</title>
<link rel="stylesheet" href="css/style.css" />
</head>
<?php
include('db.php');
if(isset($_POST['update']))
{
$parcelID = $_POST['parcelID'];
$owner = $_POST['owner'];
$rcv_date = $_POST['rcv_date'];
$pck_date = $_POST['pck_date'];
$status = $_POST['status'];
// checking empty fields
if (empty($parcelID) || empty($owner) || empty($rcv_date)||
empty($pck_date)|| empty($status)) {
if(empty($parcelID)) {
echo "<font color='red'>Parcel ID field is empty.</font><br/>";}
if(empty($owner)) {
echo "<font color='red'>Owner Name field is empty.</font><br/>";}
if(empty($rcv_date)) {
echo "<font color='red'>Received Date field is empty.</font><br/>";}
if(empty($pck_date)) {
echo "<font color='red'>Picked Up Date field is empty.</font><br/>";}
if(empty($status)) {
echo "<font color='red'>Parcel Status field is empty.</font><br/>";}
} else {
//updating the table
$result = mysql_query("UPDATE parcel SET parcelOwner = '$owner',
dateReceived = '$rcv_date', datePickup = '$pck_date', parcelStatus =
'$status' WHERE parcelID='$parcelID'");
//redirectig to the display page. In our case, it is index.php
header("Location: parcelView.php");
}
}
?>
<?php
//getting id from url
if(isset($_GET['parcelID'])){
$parcelID = $_GET['parcelID'];
}
//selecting data associated with this particular id
if(isset($parcelID)){
$result = mysql_query("SELECT * FROM parcel WHERE parcelID='$parcelID'");
while($res = mysql_fetch_array($result))
{
//$mem_id= $res['mem_id'];
$parcelID= $res['parcelID'];
$owner= $res['parcelOwner'];
$rcv_date= $res['dateReceived'];
$pck_date= $res['datePickup'];
$status= $res['parcelStatus'];
}}
?>
<body>
<body style='background: url(mailbox.jpg)'>
<div align="center">
<h1>Update Parcel Details</h1>
<form method="post" enctype="multipart/form-data">
<table>
<tr>
<Td> PARCEL ID : </td>
<td><input name="parcelID" type="text" id="parcelID" value=<?php
echo $parcelID;?>></td>
</tr>
<tr>
<Td> OWNER : </td>
<td><input name="owner" type="text" id="owner" value=<?php echo
$owner;?>></td>
</tr>
<tr>
<Td> DATE RECEIVED : </td>
<td><input name="rcv_date" type="text" id="rcv_date" value=<?php
echo $rcv_date;?>></td>
</tr>
<tr>
<Td> DATE PICKED UP : </td>
<td><input name="pck_date" type="text" id="pck_date" value=<?php
echo $pck_date;?>></td>
</tr>
<tr>
<Td> STATUS : </td>
<td><input name="status" type="text" id="status" value=<?php
echo $status;?>></td>
</tr>
<tr>
<Td colspan="2" align="center">
<input type="submit" value="Update Records" name="update"/>
</Td>
</tr>
</table>
</form>
</div>
</body>
</html>
And i got these errors
Notice: Undefined variable: parcelID in C:\xampp\htdocs\psmtest1\parcelEdit.php on line 77
Notice: Undefined variable: owner in C:\xampp\htdocs\psmtest1\parcelEdit.php on line 81
Notice: Undefined variable: rcv_date in C:\xampp\htdocs\psmtest1\parcelEdit.php on line 85
Notice: Undefined variable: pck_date in C:\xampp\htdocs\psmtest1\parcelEdit.php on line 89
Notice: Undefined variable: status in C:\xampp\htdocs\psmtest1\parcelEdit.php on line 93
I honestly can't find ways to solve this even after referring to different code examples.
