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());
$result2=mysql_fetch_array($result);
?>
<div data-role="page" id="group">
<div class="main">
<div id="header2" class="clearfix">
<table border="0" width="100%" id="table">
<tr><td colspan="5"><hr></td></tr>
<tr>
<td colspan="2" id="menu_button1">
Reset
</td>
<td align="center">
Score : 50%
</td>
<td> </td>
<td id="menu_button2">

How can I create my download button to actually download that particular file?
<a href="/path/to/image" download>
<img src="/path/to/image" />
</a>
If you want to download any file on clicking a button you must try this:
<a class="btn" href="<?= $your_path_to_file ?>" download>Download File</a>
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 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 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.

Question: While master.php runs "check" alerts twice.
I need to know why "check" alerts twice. How to solve this
<div region=center>
The scripts within the div runs twice. there is some bug with jeasy-ui. Help me how to solve that.
Technically included page alert shouldn't fire twice. it is only possible in case of you add sample.php file in php.ini as auto_append_file
i found same problem in easyui every version, when script is included in to panel/layout, the script will be run twice, the reason I think:
the page be loaded in browser ,the browser run the script of page once, when dom is loaded ,the easyui render style for the node in dom, the script in the node will be called second by easyui.
this problem isn't only in layout , but in panel, Maybe even for the every thing inherit from panel.
this problem may be in the easyui's root render method, so I can't find solved for this without src.
now i have to change easyui to another ui framework.
example for theis problem, the alert be called twice in browser:
</div>
<div region="south" class="south" border="false">
</div>
<div region="center" class="center" >
<script>
alert("here");
</script>
</div>
