I want to display form data on another page so that when I click "More View" button and the inputed data of each user will display on another page.
This is the code of the HTML form:
registerbooks.php
<!DOCTYPE Html>
<<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>Register books</title>
<link rel="stylesheet" type="text/css" href="https://stackpath.bootstrapcdn.com/bootstrap/4.4.1/css/bootstrap.min.css">
</head>
<body>
<div id='main-content'>
<form action="connect.php" method="POST">
<input type="text" name="tittle" placeholder="Book Tittle"></br>
<input type="text" name="author" placeholder="Author"></br>
<input type="text" name="copies" placeholder="Copies Available"></br>
<button type="submit" name="submit">submit</button>
<button type="reset" value="Reset">Reset</button>
</form>
</div>
</body>
</html>
This is the connection.php
<?php
$servername = 'localhost';
$username = 'root';
$password = '';
$dbname = 'list';
// Create connection
$connect = mysqli_connect($servername, $username, $password, $dbname);
// Check connection
if (!$connect) {
die("Connection failed: " . mysqli_connect_error());
}
if (isset($_POST['submit'])){
$Tittle = $_POST['tittle'];
$Author = $_POST['author'];
$Copies = $_POST['copies'];
$query = "INSERT INTO books(Tittle,Author,Copies) VALUES('$Tittle' , '$Author' , '$Copies')";
$result=mysqli_query($connect, $query);
if($result){
echo 'Available Books updated';
}
else{
echo "Failed to update";
}
}
?>
The fom is displayed in this page:
Availablebooks.php

I tried to add a delete "button"(link to file with function) it should delete a row from the database, but it didn't work. I looked for tutorials and answers on forums but found nothing how solve for my problem.
<td>Delete</td>
link from code:
The link works correctly, but when I tried to delete it just doesn't want to take 'commentId' variable and go back to test.php page
Table on website:
dbh.inc.php
<?php
$serverName = "localhost";
$dBUsername = "root";
$dBPassword = "";
$dBName = "php-login";
$conn = mysqli_connect($serverName, $dBUsername, $dBPassword, $dBName);
if (!$conn){
die("connection failed: " . mysqli_connect_error());
}
test.php
<?php
include_once 'header.php';
include "includes/dbh.inc.php";

<?php

$sql = "SELECT * FROM commenttb ORDER BY commentId DESC";
$result = mysqli_query($conn, $sql);

<?php
include "dbh.inc.php";
if(isset($_GET['commentId'])) {
$id = $_GET['commentId'];
$delete = "DELETE FROM `commenttb` WHERE `commentId` ='$id'";
$result = mysqli_query($conn, $delete);

} else {
header("Location: ../test.php?error=unknown error occurred");
}
}else {
header("Location: ../test.php?error=smth gone wrong");
}
If I press on the link "delete" it should take 'commentId' variable from row e.g. 5 and by SQL query from delete.inc.php file delete row with this id from my database
I tried change $_Get to $_POST and add method="POST" to link on delete.inc.php file, but it didn't work
I am working on an assignment in PHP and MySQL, where I am needed to create a function to delete records from a table via ID with a push of a button with JavaScript. Even though I followed by teacher's videos, it still is not able to delete the record away.
My teacher and I suspected that it has got to do with the bind_param part, but still it is not solved.
Here are the files:
db-connect.php
<?php
$servername = "localhost";
$username = "root";
$password = ""; // this should be empty
$dbName = "newDB"; // add your database name here
$conn = new mysqli($servername, $username, $password, $dbName);
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
/**
* $conn->connect_error - contains an error message from the database server (if any)
*/
}
?>
index.php

require "db-connect.php";

There's an error in your string concatenation for the url -
document.location.href = "db-deleterecord.php?=id" + id;
should be -
document.location.href = "db-deleterecord.php?id=" + id;
i would like to read out all data records from a table and give individual data records a new value in "status" according to their "id".

My problem is, when I click the button, all records are changed and not just one. I hope someone can help to solve the problem.
.........................................................................................................................................................................................................
Try using {} to embed array elements into a string and enclose 'id' value
$update = "UPDATE data Set status = '0' WHERE id = {$row['id']}"
Otherwise, your query will interpret $row and [id] as separated items:
UPDATE data Set status = '0' WHERE id = [id]
and as a result, all your rows updated
Also consider to apply the status update button to each single row, there is no way to update only one row with a general "update status" button without sending a parameter of which row id will update. For example:

i want to get the index of td that the user clicked , i have an html table fill from database using php ...
this is my index.php :
<html>
<head>
<title>Last 10 Results</title>
</head>
<body>
<table>
<thead>
</thead>
<tbody>
<tr>
<?php
session_start();
$connect = mysqli_connect("localhost","root","","test");
if (!$connect) {
die(mysql_error());
}
$results = mysqli_query($connect,"SELECT * FROM family where parent_id = 0");
while($row = mysqli_fetch_assoc($results)) {
?>
<td onclick="window.location='index2.php'"
<?php $id = $row['id'];
$_SESSION['varname'] = $id;?>>
<?php echo $row['name']?> <br/>
<?php echo $row['description']?> <br/>
<?php echo $row['parent_id']?> <br/>
</td>
<?php
}
?>

this is my index2.php :
<html>
<head>

</head>
<body>

<tbody>
<tr>
<?php
session_start();
$gg = $_SESSION['varname'];
echo $gg;
$connect = mysqli_connect("localhost","root", "","test");
if (!$connect) {
die(mysql_error());
}
$results = mysqli_query($connect,"SELECT * FROM family where parent_id = '$gg' ");
while($row = mysqli_fetch_array($results)) {

<?php echo $row['id']?> <br/>

<?php echo $row['description']?> <br/>
<?php echo $row['parent_id']?> <br/>
</td>
<?php
}
?>
</tr>
</tbody>
</table>
</body>
</html>
now i want to take the "id" of the td that the user click on,, but this code always give me the last id in my database ...
what can i do ?
Replace in Index.php:
<td onclick="window.location='index2.php'"
With:
<td onclick="window.location='index2.php?parent_id=<?php echo $row['id']; ?>'"
And in
Index2.php:
$gg = $_SESSION['varname'];
With:
$gg = (int)$_GET['parent_id'];
It's better to use $_GET variable for this than $_session (urls are search engine friendly)
I want to get data from my database with PHP code. In brief when a user log in with id & password i want to show his data only in user panel, but i got some error: Here is my user admin panel code:

You set your $_SESSION['id']= $row["Id"] . Are you sure there column Id in your table? Because you using user_id instead of Id in your query in user admin panel code
