I have a table displaying a list of users from my database and I have added a delete button beside each row so that if I want to delete that row I click the delete button and the row should disappear from my database and the table displayed on the database.
When I click delete it redirects me to another page but doesn't delete anything in the database. Please find attached my PHP for deleting users and the HTML table it is displaying from.
Thanks in advance

I'm trying to use DataTables but for some reason, it doesn't seem to be working. I'm using Bootstrap 4 and I need buttons from DataTables so that I can export the table later. I think I've added everything I need but it's not showing up. anyone know why it hasn't worked? The table is being posted from a database, it works just fine in bootstrap and all the information shows up but as soon as I try to add DataTables to it nothing seems to change.
<?php
ini_set('display_errors', 1);
ini_set('display_startup_errors', 1);
error_reporting(E_ALL);
include_once('connection.php');
if($_SERVER['REQUEST_METHOD'] == "POST" and isset($_POST['someAction']))
{
func();
}
function func()
{
$conn = mysqli_connect("localhost", "root", "", "SportsDB");
}
session_start();
if( !isset($_SESSION['username']) ){ /* Change into role = teacher or admin*/
header('Location:login.php');
}
print_r($_SESSION);
?>

Thanks for the help. I needed to call the jquery before DataTables.
I am trying to send a value to my mysql database, I am very new to php/bootstrap programming and I've tried everything but most of the guides are beyond my understanding. Please guide me in the right path so on the button click the button will update the specific database.
Here's what the button click will do:
on Uninstall button click it will send update the database like
UPDATE activate="No" FROM software WHERE uid(or id)="same id of the row where the button is clicked" [I know this mysql query is wrong]
Here's my code:

Here's screenshot of the page: https://image.ibb.co/eToeaz/Capture.png
You can send request to server by this code.
$con = new mysqli_connect("servername", "username", "password", "name");
if(!$con)
{
die("DB CONNECTION ERROR");
}
$result=mysqli_query($con, "SELECT * FROM 'table' WHERE 'something'");
$row=$result->fetch_array();
$count = mysqli_num_rows($result);
mysqli_close($con);
if( $count == 1 )
If you want it to happen instantly then use AJAX to send request to the php server, see https://www.w3schools.com/php/php_ajax_database.asp for more info.
if you want it with redirecting then use
$conn = new mysqli("DBservername", "DBusername", "DBpassword", "DBname");
if ($conn->connect_errno) {
$errormsg = ("Database Connection failed: " . $conn->connect_error );
return $errormsg;
}
$res=mysqli_query($conn, "SELECT * FROM 'table' WHERE 'something'");
$row=$res->fetch_array();
$count = mysqli_num_rows($res); // if fetch correct it returns must be 1 row
mysqli_close($conn);
if( $count == 1 ) etc
send query, update, delete etc.
$sql = "DELETE FROM 'table' WHERE 'something';
mysqli_query($conn,$sql);
Rough and bad php code but should work.
Edit after i understand what you actually asked:
When rendering results from database, anchor each button to redirect to a page /update/{rowid} or /update.php?id={rowid}
and in that link execute the query with conditions and etc.
I have a question regarding dynamic tables in html and php. My goal is to create a dynamic table that displays the queried data from mysql and displays them in a table with checkboxes so the user can select questions from a question bank and then do something with them. My problem however is getting the data to be displayed. Using a certain type of mvc architecture, I need to keep the sql out of the front end html and php portions. I was wondering if anyone had any suggestions as how to post the variables from the back end(mysql query) and send them to the front end(html and php section) via curl where I can dynamically create a table with checkboxes. I have attempted the solution using bootstrap and combining sql with html and php as well. Any help would be greatly appreciated.
<?php
include('ProfessorWelcome.php');
//set up mysql connection
$con = mysql_connect("localhost", "username", "password") or die(mysql_error());
//select database
mysql_select_db("username", $con) or die(mysql_error());

This is how I would do it.
I added the ob_start() and ob_flush() so the Top of the page is being transmitted as you create the table.
Moved <title> to immediately follow <head>
Very Important: Moved CSS above JS in the <head>
I used heredoc syntax: PHP Manual Heredoc Syntax
Added MYSQL_NUM to:
mysql_fetch_array($results, MYSQL_NUM))
$row[0] and $row[1] can be used in a double quoted string without concatenation dots. Can also be used in here doc. $row['Question'] and $row['Difficulty'] can not.
Do you realize the overhead associated with jQuery? You do not need any JS in this page. But you created a lot more work for the Browser and are making the visitor wait while the Browser does all that unnecessary work.
I would 86 the JS and jQuery. And NO Bootstrap. Learn CSS.

<?php

<?php
$db = new PDO('mysql:host=localhost;dbname=cvtool;charset=utf8', 'user', 'pass'); // change these to your own database details
$db->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION); // later, change ERRMODE_WARNING to ERRMODE_EXCEPTION so users wont see any errors
$db->setAttribute(PDO::ATTR_EMULATE_PREPARES, false);
$department = isset($_GET['department'])? $_GET['department']: null;
$sql = 'SELECT *
FROM education
WHERE school LIKE ?;
$q = $conn->prepare($sql);
$q->execute(array('%$department%');
$q->setFetchMode(PDO::FETCH_ASSOC);
while ($r = $q->fetch()) {
echo sprintf('%$department', $r['school']);
}

The problem is that no matter how I change it, it still gives me an error. The error is at these specific lines:
while ($r = $q->fetch()) {
echo sprintf('%$department', $r['school']);
}
The error might be just something missing or something extra that I put without realizing it. I know the code is about a very specific case, but still any help is appreciated.
You never close the following string variable :
$sql = 'SELECT *

WHERE school LIKE ?;
I am developing a smartphone web app that is a game of question answer using jquerymobile API.
when a user click on next button that is a anchor tag then i switch to other page and increment the $_SESSION['questionNo'] value. The problem is $_SESSION['questionNo'] value increment from 1 to 4 and then again became $_SESSION['questionNo'] is 1. why it's happening i don't know. Here is my code
<?php session_start();
include("connect.php");
include("header1.php");
$attemp=$_SESSION['questionNo'];
echo $attemp;
$sql = sprintf("select * from question order by pk_id ASC limit %s,%s",$attemp,1);
$result = mysql_query($sql) or die(mysql_error());

<?php
session_start();
++$_SESSION['questionNo'];
header('Location:startGame.php');
exit;
?>
