From the table image below:
Is there any ways that I used nodeID 101 as my indicator. Then I want to retrieve battery value of Node102 which is lower than the battery value of NodeID101... Same goes to node103, it will also compare with node101 whereby if its battery value lower than node101, result is displayed.
Thanks for your guides!

i wanted to ask I would I add up the points of all the drivers in the table produced below by the following code as this only displays points of all the drivers in each row ... There is a table Points which has points, position and a table Drivers having forename, surname.
<?php
session_start();
if ( !isset($_SESSION['loggedin']) ) {
header("Location: login.php");
}
$con=mysqli_connect("xxxxx","xxxxx","xxxxx","xxxx");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT Drivers.forename, Drivers.surname, Teams.name, Teams.engine, Points.points
From Drivers, Teams, Points");
echo "<table border='1'>
<tr>
<th>First name</th>
<th>Last name</th>
<th>Team Name</th>
<th>Engine</th>
<th>Points</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['forename'] . "</td>";
echo "<td>" . $row['surname'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['engine'] . "</td>";
echo "<td>" . $row['points'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
in your code, before the $while
$counter=0
while($row = mysqli_fetch_array($result))
{
$counter += $row['points'];
echo "<tr>";
echo "<td>" . $row['forename'] . "</td>";
echo "<td>" . $row['surname'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['engine'] . "</td>";
echo "<td>" . $row['points'] . "</td>";
echo "</tr>";
}
echo $counter; //echoes sum of points
I'm trying to display members from my database using PHP, however the last name goes in with the first name and I'm not quite sure why... Could anyone point me in the right direction?
<?php
$mysql_db_hostname = "localhost";
$mysql_db_user = "alex";
$mysql_db_password="";
$mysql_db_database="gym";
$con = mysql_connect($mysql_db_hostname, $mysql_db_user, $mysql_db_password) or die("Could not connect database");
mysql_select_db($mysql_db_database, $con) or die("Could not select database");
$query = mysql_query("select * from users WHERE Category='Member'");
echo "<table border=1>
<tr>
<th>Users ID</th>
<th>First Name</th>
<th>Last Name</th>
</tr>";
while($row =mysql_fetch_assoc($query))
{
echo "<tr>";
echo "<td>" . $row['user_id']."<br>" . "</td>";
echo "<td>" . $row['First_Name']."<br>" . "</td";
echo "<td>" . $row['Last_Name']."<br>" . "</td";
echo "</tr>";
}
echo "</table";
?>
You aren't closing the tags. Syntax highlighter would show the error.
while($row =mysql_fetch_assoc($query))
{
echo "<tr>";
echo "<td>" . $row['user_id']."<br>" . "</td>";
echo "<td>" . $row['First_Name']."<br>" . "</td"; <-----------
echo "<td>" . $row['Last_Name']."<br>" . "</td"; <------------
echo "</tr>";
}
You are not closing your <td> tags properly
echo "<td>" . $row['First_Name']."<br>" . "</td>";
//^here
echo "<td>" . $row['Last_Name']."<br>" . "</td>";
//^and here
So the output is all one cell with both variables printed inside
You forgot to close the td on your first name field.
Just change
</td
to
</td>

Here in table one , I used aNun_id to get the data from another PHP file with "GET" command.
In the table two, I want bNun_id to show its related data in that table. How do i call bNun _id data to the second table from table one. Pls help me..
Are those two tables in the same page?
If so, You need to append the bNum_id to the same query string to use both aNum_id & bNum_id.
echo "<td><a href='?aNun_id=".$_GET["aNun_id"]."&bNun_id=".$row['b_number']."'>" . $row['b_number'] . "</a></td>";
I'm trying to assign anID to the table I'm generating with PHP but it keeps returning an error. Here is the full code that works fine so far. All I want is to add an 'id' to the table so I can apply css styles to it in the relevant sheet
<?php
$con=mysqli_connect("localhost","<un>","<pw>","monitor");
// Check connection
if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con,"SELECT * FROM presnationalresults ORDER BY Percentage DESC");
echo "<table border='1'>
<tr>
<th>President</th>
<th>Party</th>
<th>Votes</th>
<th>Percentage</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['PresidentName'] . "</td>";
echo "<td>" . $row['PartyCode'] . "</td>";
echo "<td>" . $row['Votes'] . "</td>";
echo "<td>" . $row['Percentage'] . "</td>";
}
echo "</table>";
mysqli_close($con);
Any help? maybe I'm going about it the wrong way?
Please try below block of code . I have added table id and also close </tr> inside while loop
<?php
$con = mysqli_connect("localhost", "<un>", "<pw>", "monitor");
// Check connection
if (mysqli_connect_errno()) {
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$result = mysqli_query($con, "SELECT * FROM presnationalresults ORDER BY Percentage DESC");
echo "<table border='1' id='table-id'>
<tr>
<th>President</th>
<th>Party</th>
<th>Votes</th>
<th>Percentage</th>
</tr>";
while ($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['PresidentName'] . "</td>";
echo "<td>" . $row['PartyCode'] . "</td>";
echo "<td>" . $row['Votes'] . "</td>";
echo "<td>" . $row['Percentage'] . "</td>";
echo "</tr>"; // you forget close tr
}
echo "</table>";

I have MAMP (local hosted SQL,WEB etc server) the database name is :NKTDEBITS the table name is :Insurance and the column on the table is STATECOV. I know I'm close with this but still get a black in the field that should generate the total, anyone got a idea?

You need a GROUP BY to go along with your SUM. I don;t know enough about you table to let you know what column you should use for this.
You should be handling potential error cases whenn you query the database, as you will quickly see when you are getting database/query errors.
You should also look to use mysqli or PDO instead of the deprecated mysql_* functions.
