if ($this->databaseConnection()) {
// database query, getting all the info of the selected user
$query_user = $this->db_connection->prepare("SELECT * FROM users WHERE user_name='$_SESSION['user_name']'");
$query_user->bindValue(':user_name', $user_name, PDO::PARAM_STR);
$query_user->execute();
// get result row (as an object)

I am new to php mysql & have this query where i want to display the output of mysql query on button badge. I have tried the following code
Kindly help .
<?php

As long as you have verified the settings and the query is correct the above line should output what you are looking for.
EDIT
<?php
$con=mysqli_connect("localhost","root","") or die("Failed to connect with database!!!!");
mysqli_select_db($con,"sales");
$sth = "select sum(sal) as Salary from `sales` ";
$result = mysqli_query($con,$sth);
$row = mysqli_fetch_assoc($result);
Try That
I am creating a PHP/MySQL based application and it need to be able to carry over session variables into the DataTable plugin I use on a page in my app. The application is rather complicated, so I will explain how it works before I ask specific questions.
On index.php, there is a dropdown menu that shows the departments that use this application within my organization. The department list is generated by a mySQL table that has their department name and department code. The $dept variable stores the department code value from the selected option in the dropdown menu on submit. In turn, the $_SESSION["department"] variable stores $dept and redirects to the checkin page if successful.
<?php
require_once('connection.php');
session_start();
if (isset($_POST['submit']))
{
$dept = $_POST['dept'];
$_SESSION["department"] = $dept;
header("Location: checkin.php");
}
?>

The session variable is then carried throughout the site and is used to determine which table needs to be shown. For instance, in checkin.php, we need to display staff members in a dropdown list. We have multiple tables based on the departments using the application. One table we have is called ts_staff If the session variable is stored as the string ts, we do the following steps to make sure the app is connecting to the right database:
We store the session variable from index.php into a global variable on checkin.php $dept = $_SESSION[department];
We create another new variable to concatenate the global variable and the _staff string which is used in all our mySQL staff tables: $staffTable = $dept . "_staff";
Lastly, we use the $staffTable variable as the database table that needs to be displayed: $query = mysqli_query($VisitorManagement, "SELECT * FROM {$staffTable}");
Here's the full checkin.php code:
<?php
// connect to database
require_once('connection.php');
session_start();
//get session variable, if empty, unset and logout
if(empty($_SESSION['department'])) {
session_unset();
session_destroy();
header("Location: index.php");
} else {
$dept = $_SESSION[department];
}
//submit values on submit
if (isset($_POST['submit']))
{
// store form data values
$suid = mysqli_real_escape_string($VisitorManagement, $_POST['suid']);
$staff = mysqli_real_escape_string($VisitorManagement, $_POST['staff']);
$checkinTable = $dept . "_checkin";
// insert varaibles into table rows
$sql = "INSERT INTO {$checkinTable} (suid, staffMember) VALUES ('$suid', '$staff')";
// check if row was inserted correctly
if (mysqli_query($VisitorManagement, $sql)) {
header('Location: thank-you.php');
} else {
echo "Error: " . $sql . "<br>" . mysqli_error($VisitorManagement);
}
}
?>

The problem is that on reports.php, I am using the DataTables plugin to dynamically organize and filter a table, but I need to be able to carry the session variable over into the plugin so it knows to organize the specific table based on what the user selected on the index.php screen.
reports.php just calls DataTables and using another page, response.php to turn the data from the table into JSON to be displayed. Here's reports.php:
<?php session_start();
if(empty($_SESSION['department'])) {
session_unset();
session_destroy();
header("Location: index.php");
} else {
$dept = $_SESSION[department];
}
$checkinTable = $dept . "_checkin";

In response.php, I need to able to replace ts_checkin, which is shown on this line:
$sql = "SELECT id, suid, staffMember, studentName, studentEmail, date_format(checkinDateTime, '%b %d, %Y, %h:%i %p') as checkinDateTime FROM `ts_checkin`";`
with a variable called $checkinTable that would concatenate similar to how checkin.php does with the staff table. So essentially I would like to have $checkinTable = $dept . "_checkin" with $dept equaling the value of the session variable.
When I go to do this, I get this error from DataTables: DataTables warning: table id=checkin - Invalid JSON response. For more information about this error, please see http://datatables.net/tn/1
Is it possible to get this working? I would like to keep DataTables as its the best way to achieve on-the-fly table filtering, searching, and sorting (plus it's a highly requested feature by our departments). But I need to be able to set the table based on the session variable.
I apologize for the length of this question. If there needs to be clarification, let me know.
I'm not certain to understand the question...
Are you saying this is not working ?
Did you try it written like this?
(notice the space after FROM. It is necessary!)
$checkinTable = $dept . "_checkin";
$sql = "SELECT id, suid, staffMember, studentName, studentEmail, date_format(checkinDateTime, '%b %d, %Y, %h:%i %p') as checkinDateTime FROM " . $checkinTable;
For sure, $dept has also to be defined.
And the resulting $checkinTable has to be an existing table name.
Ok...
This looks to be missing in your response.php:
session_start();
$dept = $_SESSION[department];
$checkinTable = $dept . "_checkin";
I'm trying to develop a login system in PHP which has faculty_login.php which displays faculty_login_option.inc.php which has a login form and if $_SESSION['f_id'] is set it redirects to faculty_upload_option.php. where faculty details are fetched from faculty_table using $f_id = $_SESSION['f_id'] as the primary key.but $_SESSION['f_id'] is always returning 1 and user is logging in as the user whose f_id is 1.

Are you destroying session correctly on logout? Are you setting session id before hitting the condition somewhere? What is the value before hitting the comparion condition?
Can someone please help me understand why the below function works in option.php but does not work in main.php? From what I'm seeing, it looks as if the query is not going through when the function is called on main.php; however, it clearly goes through on option.php.
custom_functions.php
function fetch_options(){
global $connection;
$query = "SELECT * FROM table";
$result = mysqli_query($connection, $query);
while($row = mysqli_fetch_assoc($result)){
echo "<option value=\"{$row['a']}\">{$row['b']}</option>";
}
mysqli_free_result($result);
mysqli_close($connection);
}
option.php
<?php
require_once('lib/db.php');

The included nav.php file contained a mysqli_close call and terminated the connection before the fetch_options() function was run.
What i wrong with this code below. I am trying to get it to echo to another page but it does not seem to pick up the data that is on the database.
<?php
{
// connect to server
mysql_connect("localhost", "u", "") or die(mysql_error());

mysql_select_db("") or die(mysql_error());
//Create a query that selects all data from the PATIENT table where the username and password match
$query = "SELECT`Appointment_id`, `Doctor_id`, `Patient_id`, `Appointment_time`, `Appointment_date` FROM `Appointment`";
//executes query on the database
$result = mysql_query ($query) or die ("didn't query");
//this selects the results as rows
$num = mysql_num_rows ($result);
//if there is only 1 result returned than the data is ok
if ($num == 1)
{
$row=mysql_fetch_array($result);
$_SESSION['Appointment_id'] = $row['Appointment_id'];
$_SESSION['Doctor_id'] = $row['Doctor_id'];
}

please add at the top
session_start();
since you are using $_SESSION .. you need to use session_start() immediately after php opening tag
<?php
session_start();
and not only on this page .. session_start() should be there on every page where you want you use session_start() .. otherwise $_SESSION is not accessible..
Please use session_start() on both of the pages, if you dont start that you will not be able to use that
EDIT
Create a test page to see your sessions are working?
if yes then test that on other page
also try adding a simple echo in your if condition where you are setting the session values. If that echo triggers it means your code is correct and something is wrong with SESSION. And if echo dont trigger, it means your code is not correct and sessions are not being set
if your just trying to get the first row
$query = "SELECT `Appointment_id`, `Doctor_id`, `Patient_id`, `Appointment_time`, `Appointment_date` FROM `Appointment` WHERE rownum = 1 ; ";
Edit:
Ok so here I believe the logical error lies
$query = "SELECT `Appointment_id`, `Doctor_id`, `Patient_id`, `Appointment_time`, `Appointment_date` FROM `Appointment`";
$result = mysql_query ($query) or die ("didn't query");
$num = mysql_num_rows ($result);
if ($num == 1)
{
}
Since your query has no WHERE clause, it is returning all records that there are, and You are setting the SESSION values only when there is 1 record. You should also have an else condition to see what happens in real.
Create a query that selects all data from the PATIENT table where the username and password match
But your query does not do that, it gets data for all the PATIENTs
For example if your username and password came from a POSTed form then you could do
$username=mysql_real_escape_string($_POST["username"]);
$password=mysql_real_escape_string($_POST["password"]);
Then you could use both those values inside a WHERE clause. Since I do not know the structure of your tables apart from just reading your query, I can not write it exactly. But just to give you an idea, a where could be like
$query="SELECT id from YourTable where $username='$username' and password='$password'"
Very important to note since you are a beginner : mysql_* functions should no longer be used. If you are starting, don't start with something that's gone. Read about mysqli_* or PDO
Edit 2:
Ok great, so do this
On successful login where you store Patient's details in SESSION, also store Patient_id like $_SESSION['Patient_id'] = $row['Patient_id']; //or maybe its just id. Check your table
On Appointment.php change your query to
$pid=intval($_SESSION["Patient_id"]);
$query = "SELECT Appointment_id, Doctor_id, Patient_id, Appointment_time, Appointment_date FROM Appointment where Patient_id=$pid";
Add an else condition below your if($num==1) { } block like
PHP
else{
echo "Somehow we didn't get 1 record";
die();
}
