<?php echo ''.$row['Salary'].''; ?>
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've been working on developing fullCalendar drag and drop events with a resource column. For now, I've hard coded the draggable events area; now trying to fetch it from the database.
The database previously had two tables - Resources and Events. The events after being dropped on the calendar, gets updated in the events table. The resource column is being fetched from the database and for adding new resources, I've built a rooms button which saves the new resources in the resource table.
Till now, I only had five draggable events in the main file, but now I'm working on fetching those from database as well. So, I created one more table in the database named draggableevents. The table contains two columns id and EventName.
Here's the code:
draggableevents.php
<?php
require "connection.php";
$conn = DB::databaseConnection();
$conn->beginTransaction();
$sql = "Select * FROM DraggableEvents";
$stmt = $conn->prepare($sql);
if ($stmt->execute()) {
while($result = $stmt->fetch(PDO::FETCH_ASSOC));
return $result;
} else {
return null;
}
?>
form.php

<label for='drop-remove'>remove after drop</label>
</p>

<div id='calendar-container'>

</div>
The above code results in a blank draggable events area. The draggableevents.php file doesn't seem to be loaded on refreshing the page. I don't see it in the network panel and hence no error related to it.
There are some obvious logical issues, none of which have anything much to do with fullCalendar:
1) I have mentioned this a number of times before in your previous questions: return does not return a value when you aren't inside a function. Where do you imagine you are returning that to, exactly? require doesn't have any way to
2) even if that worked, you'd never return any events, because your while loop is closed and doesn't do anything.
3) $result would be out of scope outside your while loop anyway.
4) You never execute your query
5) You didn't echo the event name.
You need to get all your database results into an array, and then loop through that array to generate as many fc-event divs as there are entries in the array.
Here's one way to do it - I've put the functionality of draggableevents.php into a function which you can call when you need it.
draggableevents.php
<?php
require "connection.php";
function getDraggableEvents() {
$conn = DB::databaseConnection();
$sql = "Select * FROM DraggableEvents";
$stmt = $conn->prepare($sql);
$stmt->execute();
$results = array();
while($row = $stmt->fetch(PDO::FETCH_ASSOC)) {
$results[] = $row;
}
return $results;
}

This is the query of my index should print me all the tables in my db which I connect in init.php that comes included , the part is loaded into a html template tiny butstrong , this is the structure of html

Now , I wish that clicking the button in the index is given me to output the list of tables in the db , but at present the query was
code:
if ($_SERVER['REQUEST_METHOD'] === 'POST'){
$query = "SELECT * FROM information_schema.tables";
$risultati=$db->mysqli_query($query);
while ( $row = $risultati->fetch_row() ){
$table = $row[0];
echo '<h3>'.$table.'</h3>';
}
}
I will not print anything, does anyone have any idea ? thank you
First of all, unless you're using a custom class, I think that you confuse procedural and objected oriented style.
This doesn't work:
$db->mysqli_query( $query );
This works:
$db->query( $query );
In addition, SELECT * FROM information_schema.tables doesn't show all the tables in our database. It display instead all the rows in table TABLES from database information_schema (it's not the same: see more about information_schema tables).
To display a list of all tables from your current database, use this query:
"SHOW TABLES"
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');
require_once('lib/custom_functions.php');
echo "<select><option value=\"0\">Unknown</option>";
fetch_options();
echo "</select>";
?>
main.php
<?php
require_once('lib/db.php');
require_once('lib/custom_functions.php');
?>

I am pulling data from a MySQL database and plotting with Flot. My problem is in our DB design.
I have 1 table that contains the following columns:
ID (auto incremented) (key)
Timestamp
SensorData (looks like: 34534.3 32452.4 23454.6 6523.45 67546.4 2233)
I would like to parse out my sensor data so I can create Flot plots with individual sensor data. Right now, I am able to plot the ID vs Timestamp and that works. Here is my code:
