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">

And i got these errors
Notice: Undefined variable: parcelID in

Notice: Undefined variable: status in

I honestly can't find ways to solve this even after referring to different code examples.
You can check that whether the variable is coming as you thinks or not . You can dump all variables sent using POST method with the help of var_dump() or print_r() like this -
<?php
include('db.php');
if(isset($_POST['update']))
{
echo '<pre>';
print_r($_POST);
echo '</pre>';
$parcelID = $_POST['parcelID'];
$owner = $_POST['owner'];
$rcv_date = $_POST['rcv_date'];
$pck_date = $_POST['pck_date'];
$status = $_POST['status'];
...
?>
and you can check the key in $_POST and do the required changes .
Try adding an else after your if(isset($parcelID)) condition
if(isset($_GET["parcelID"])){
$parcelID = mysql_real_escape_string($_GET["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'];
}
} else {
$parcelID = '';
$owner = '';
$rcv_date = '';
$pck_date = '';
$status = '';
}
Too many isset() condition which I think could be lessen, so I removed the first if(isset($_GET["parcelID"])) condition and just go straight and replace the if(isset($parcelID)) with it.
Use mysqli_* extension instead of deprecated mysql_*.

In my system, I have a function to update the data. After I click 'update' button, the data is updated at the database, but it also displays an error like this:

The problem is that you are using $_SERVER["PHP_SELF"] as the form action.
This removes the $_GET variables from the redirected page which means that you will be redirected to eg index.php instead of index.php?badgeid=1
This as a result makes this line throw a notice $badgeid = $_GET['badgeid'];
and makes your query to have no results so the rest variables are never initialized which in turn results to the rest notices you get.
In order to solve this you could be using $_SERVER['REQUEST_URI'] instead which will keep the variables or save and pass the badgeid by other means.

Declare array assigned to those before entering into the for loop like the following
$bookid = array();
$title = array();
$price = array();
$author = array();
//for loop goes here
Instead of this type I would like to suggest you to have a single array as follows and then store in it
$books = array();
for($i = 0; $i <= $records; $i++){
$books[$i]['bookid'] = $_POST[$index1];
$books[$i]['title'] = $_POST[$index1];
$books[$i]['price'] = $_POST[$index1];
$books[$i]['author'] = $_POST[$index1];
}
Now loop the above $books array as follows, which will be very convenient to achieve
foreach($books as $book){
}

I am trying to make a login session with PHP and I recieve and error at "username" field of my database.
My source code is here:
index.php
<?php
session_start();
if(isset($_POST['bttLogin'])){
require 'connect.php';
$username = $_POST['username'];
$password = $_POST['password'];
$result = mysqli_query($con, 'SELECT * FROM account WHERE username=" '.$username.' " AND password="'.$password.' " ');
if (mysqli_num_rows($result)==1){
$_SESSION['username'] = $username;
header('Location: welcome.php');
}
else
echo "Account invalid";
}
if(isset($_POST['username'])){
$filename = $_POST['username'];
}
if (isset($_GET['logout'])){
session_unregister('username');
}
?>
<form method="post">

<td><input type = "password" name="password"></td>
</tr>
<tr>
<td> </td>
<td><input type = "submit" name="bttLogin" value="Login"></td>
</tr>
</table>
</form>
I made my connection with my database, but it keeps saying that username is undefined. Please help. (Solved)
Seems you just don't have index 'username' in $_SESSION var.
You need to check and initialize it if needed -- something like this:
if (!isset($_SESSION['username'])) {
if (!is_array($_SESSION)) {
$_SESSION = [];
}
$_SESSION['username'] = $username;
}

I am making a insertion form to add a product to the mysql database. I am using echo command to print the query. The printed query is showing empty values like this:

This location of this page is root>admin>product_add.php. What seems to be the problem?
Oh, I have also used tinymce text editor in the textarea.
You are using Hyphen - signs in the HTML form for the field names; but when you try to read in PHP, you are using underscores.
$product_cat = $_POST['product_cat'];
$product_brand = $_POST['product_brand'];
$product_title = $_POST['product_title'];
$product_price = $_POST['product_price'];
$product_desc = $_POST['product_description'];
$product_keywords = $_POST['product_keywords'];
Use below code instead of above
$product_cat = $_POST['product-cat'];
$product_brand = $_POST['product-brand'];
$product_title = $_POST['product-title'];
$product_price = $_POST['product-price'];
$product_desc = $_POST['product-description'];
$product_keywords = $_POST['product-keywords'];

The lines that gives me the errors is this if($_GET["Action"] == "Del")

Thanks in advance if you can help me out.
You need to take whole code using $_POST or $_GET arrays inside if block and check for any of the main $_GET/$_POST variable that is set by (isset() method) if it is set then do that stuff in the if block else don't.
Check whether the index is set in the arrays before using them, like so:
if (isset($_GET["Action"]) {
if($_GET["Action"] == "Del") {
// Do stuff
}
}
As #A.B mentioned in the other answer, you should always do this check.
The reason you're getting this error is because the GET/POST requests don't have a value set for this index on the client side.
