My question is that why there are blank values for HW1/HW2/HW3 columns when I ran the code in the browser?.
Studentid and Sum columns displayed the code correctly. Any ideal how to fix this?
<?php
$result = mysqli_query($con,"SELECT studentid,SUM(hw1+hw2+hw3)
FROM grade
GROUP BY studentid");
echo "<table border='1'>
<tr>
<th>StudentID</th>
<th>HW1</th>
<th>HW2</th>
<th>HW3</th>
<th>SUM</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['studentid'] . "</td>";
echo "<td>" . $row['hw1'] . "</td>";
echo "<td>" . $row['hw2'] . "</td>";
echo "<td>" . $row['hw3'] . "</td>";
echo "<td>" . $row['SUM(hw1+hw2+hw3)'] . "</td>";
;}
echo "</table>";
mysqli_close($con);
?>
just change your query to this
"SELECT studentid,hw1, hw2, hw3, SUM(hw1+hw2+hw3) as hw
FROM grade
GROUP BY studentid"
Because you did not select the columns, try:
$result = mysqli_query($con, 'SELECT `studentid`, `hw1`, `hw2`, `hw3`, SUM(`hw1`+`hw2`+`hw3`) as `sum` FROM `grade` GROUP BY `studentid`');
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['studentid'] . "</td>";
echo "<td>" . $row['hw1'] . "</td>";
echo "<td>" . $row['hw2'] . "</td>";
echo "<td>" . $row['hw3'] . "</td>";
echo "<td>" . $row['sum'] . "</td>";
}
I'm not sure, since your question is poorly written. But I think you just need to do this to get the values:
SELECT studentid,hw1,hw2,hw3,SUM(hw1+hw2+hw3)

this is my php code for sql query its giving me same value multi time
if (isset($_GET["q"]))
{
$q= $_GET["q"];
$link=mysqli_connect("localhost","root","");
mysqli_select_db($link,"onesports");
$result=mysqli_query($link,"select players.full_name, team.* from players,team where team.team_name='" .$q. " ' and players.team_name=team.team_name ");
echo "<table>
<tr>
<th>Firstname</th>
<th>Lastname</th>
<th>Age</th>
<th>Hometown</th>
<th>Job</th>
</tr>";
while($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<a href=>" . $row['full_name'] . "</a>";
echo "<td>" . $row['image'] . "</td>";
echo "<td>" . $row['team_name'] . "</td>";

echo "<td>" . $row['captain'] . "</td>";
echo "<td>" . $row['coach'] . "</td>";
echo "</tr>";
}
echo "</table>";
}
else {
echo "no result found.";
}
its giving me this output
enter image description here
i want only player name and remaining value want for one time
You should use INNER JOIN in this case.
just update your code with below code.
$result = mysqli_query($link, "SELECT `players`.full_name,`team`.* FROM `players` INNER JOIN `team` ON `players`.team_name= `team`.team_name AND `team`.team_name='".$q."'");
I seem to be having an issue with my HTML formatting. I am calling the database to display all information within the table on a webpage. I have got the information coming down into the table. Unfortunately the table is adding an additional row to the bottom of the table making 4 rows when in fact there is only 3 rows displaying in the database.
Any idea as to why?
<?php
//connect to the server
$link = mysql_connect('*****', '*****', '****');
if (!$link) {
die('Could not connect: ' . mysql_error());
}
mysql_select_db('******');
$query = mysql_query("SELECT * FROM tablename");
echo "<table border='1'>
<tr>
<td>Date</td>
<td>Region</td>
<td>Cameraman</td>
<td>Livestream?</td>
<td>Event Title</td>
<td>Lecturer</td>
<td>Time</td>
<td>Speaker</td>
<td>ICE Contact</td>
<td>Venue Address</td>
<td>Venue Contact</td>
<td>Additional Comments</td>
<td>On App?</td>
</tr>";
WHILE($rows = mysql_fetch_array($query)):
echo "<tr>";
echo "<td>" . $rows['date'] . "</td>";
echo "<td>" . $rows['region'] . "</td>";
echo "<td>" . $rows['cameraman'] . "</td>";
echo "<td>" . $rows['livestream'] . "</td>";
echo "<td>" . $rows['eventitle'] . "</td>";
echo "<td>" . $rows['lecturer'] . "</td>";
echo "<td>" . $rows['time'] . "</td>";
echo "<td>" . $rows['speaker'] . "</td>";
echo "<td>" . $rows['icecontact'] . "</td>";
echo "<td>" . $rows['venueaddress'] . "</td>";
echo "<td>" . $rows['venuecontact'] . "</td>";
echo "<td>" . $rows['additioncomments'] . "</td>";
echo "<td>" . $rows['onapp'] . "</td>";
echo "</tr>";
endwhile;
echo "</table>";
?>

Update your while loop with the following:
WHILE($rows = mysql_fetch_array($query)):
$rows = array_filter($rows);
if (!empty($rows)) {
echo "<tr>";
echo "<td>" . $rows['date'] . "</td>";
echo "<td>" . $rows['region'] . "</td>";
echo "<td>" . $rows['cameraman'] . "</td>";
echo "<td>" . $rows['livestream'] . "</td>";
echo "<td>" . $rows['eventitle'] . "</td>";
echo "<td>" . $rows['lecturer'] . "</td>";
echo "<td>" . $rows['time'] . "</td>";
echo "<td>" . $rows['speaker'] . "</td>";
echo "<td>" . $rows['icecontact'] . "</td>";
echo "<td>" . $rows['venueaddress'] . "</td>";
echo "<td>" . $rows['venuecontact'] . "</td>";
echo "<td>" . $rows['additioncomments'] . "</td>";
echo "<td>" . $rows['onapp'] . "</td>";
echo "</tr>";
}
endwhile;
echo "</table>";
array_filter() function's default behavior will remove all values from array which are equal to null, 0, '' or false.
It seems that you have empty data in your database, as many lines are empty
Check your database for empty records or run the query
DELETE FROM table_name WHERE column='';
I am trying to add a column before my first column that starts numbering each record, starting from 1. I was trying to add autoincrement to this line echo "" . $row['ss'] . "";, but that does not seem to want to work. Any ideas how to do this?
My code looks like this:
$result = mysqli_query($con,"SELECT * FROM `results` WHERE Event='100' AND Gender='M' ORDER BY Performance ASC");
echo "<table border='0'>
<tr>
<th align='left'>Pos</th>
<th align='left'>Event</th>
<th>Performance</th>
<th>Wind</th>
<th>Place</th>
<th align='left'>Name</th>
<th align='left'>Surname</th>
<th>Age</th>
<th>Team</th>
<th>Meet</th>
<th>Date</th>
</tr>";
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['ss'] . "</td>";
echo "<td>" . $row['Event'] . "</td>";
echo "<td>" . $row['Performance'] . "</td>";
echo "<td>" . $row['Wind'] . "</td>";
echo "<td>" . $row['Pos'] . "</td>";
echo "<td width='100' align='left'>" . $row['Surname'] . "</td>";
echo "<td Width='100'>" . $row['Name'] . "</td>";
echo "<td>" . $row['Age'] . "</td>";
echo "<td>" . $row['Team'] . "</td>";
echo "<td>" . $row['Meet'] . "</td>";
echo "<td>" . $row['Date'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($con);
?>
Add this line in header
<th align='left'>#</th>
And here php code
$count = 1;
while($row = mysqli_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $count . "</td>";
echo "<td>" . $row['ss'] . "</td>";
echo "<td>" . $row['Event'] . "</td>";
echo "<td>" . $row['Performance'] . "</td>";
echo "<td>" . $row['Wind'] . "</td>";
echo "<td>" . $row['Pos'] . "</td>";
echo "<td width='100' align='left'>" . $row['Surname'] . "</td>";
echo "<td Width='100'>" . $row['Name'] . "</td>";
echo "<td>" . $row['Age'] . "</td>";
echo "<td>" . $row['Team'] . "</td>";
echo "<td>" . $row['Meet'] . "</td>";
echo "<td>" . $row['Date'] . "</td>";
echo "</tr>";
//other code
$count=$count+1;
}
A better solution would be to use a variable counter to "number" your rows:
$counter = 1;
while($row = mysqli_fetch_array($result))
echo "<td>" . $counter . "</td>";
$counter++;
}
This is the right way to do it since if that ss column is the mysql auto increment, then your rows will not be numbered by the SORT but rather from the order in which they were inserted into the database regardless of any sorting you apply.
Try to change fetch_array with fetch_assoc
can anyone help?
Apologies if I'm being stupid but I'm very new to this and I don't really know what I'm doing...
I have generated a table which uses php to get data from a mysql database, but I want to put an extra column at the end (of every row) which contains a link. The link will be to further details about that entry.
The code I have which displays the table is as follows:
$result = mysql_query("SELECT * FROM orders");
echo "<table border='5'>
<tr>
<th>order_no</th>
<th>ord_date</th>
<th>est_completion_date</th>
<th>status</th>
<th>invoice_date</th>
<th>inv_amount</th>
<th>name</th>
<th>fName</th>
<th>lName</th>
</tr>";
// -- Use 'while' to check each row in $result in turn:
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['order_no'] . "</td>";
echo "<td>" . $row['ord_date'] . "</td>";
echo "<td>" . $row['est_completion_date'] . "</td>";
echo "<td>" . $row['status'] . "</td>";
echo "<td>" . $row['invoice_date'] . "</td>";
echo "<td>" . $row['inv_amount'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['fName'] . "</td>";
echo "<td>" . $row['lName'] . "</td>";
echo "</tr>";
}
echo "</table>";
Like I say, I'm a beginner. Basically I am reasonably happy (using the code above) in making html tables which display the results of a mysql query. However I need the users to be able to click on rows/cells in order link to other tables.
Any help much appreciated...
echo "<table border='5'>
<tr>
<th>order_no</th>
<th>ord_date</th>
<th>est_completion_date</th>
<th>status</th>
<th>invoice_date</th>
<th>inv_amount</th>
<th>name</th>
<th>fName</th>
<th>lName</th>
<!-- extra column here -->
<th> </th>
</tr>";
while($row = mysql_fetch_array($result)) {
echo "<tr>";
echo "<td>" . $row['order_no'] . "</td>";
echo "<td>" . $row['ord_date'] . "</td>";
echo "<td>" . $row['est_completion_date'] . "</td>";
echo "<td>" . $row['status'] . "</td>";
echo "<td>" . $row['invoice_date'] . "</td>";
echo "<td>" . $row['inv_amount'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['fName'] . "</td>";
echo "<td>" . $row['lName'] . "</td>";
// add link here
echo "<td><a href=''>link</a></td>";
echo "</tr>";
}
Please note: You should stop using mysql_* functions. They're being deprecated. Instead use PDO (supported as of PHP 5.1) or mysqli (supported as of PHP 4.1). If you're not sure which one to use, read this article.
try this. add a column. It will link to another page "view_more_details.php". To identify rows uniquely, pass a unique id with this link. Here I passed order_no. In the
"view_more_details.php" page, you can select this value by using $_GET['key']
$result = mysql_query("SELECT * FROM orders");
echo "<table border='5'>
<tr>
<th>order_no</th>
<th>ord_date</th>
<th>est_completion_date</th>
<th>status</th>
<th>invoice_date</th>
<th>inv_amount</th>
<th>name</th>
<th>fName</th>
<th>lName</th>
<th> </th>
</tr>";
// -- Use 'while' to check each row in $result in turn:
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td>" . $row['order_no'] . "</td>";
echo "<td>" . $row['ord_date'] . "</td>";
echo "<td>" . $row['est_completion_date'] . "</td>";
echo "<td>" . $row['status'] . "</td>";
echo "<td>" . $row['invoice_date'] . "</td>";
echo "<td>" . $row['inv_amount'] . "</td>";
echo "<td>" . $row['name'] . "</td>";
echo "<td>" . $row['fName'] . "</td>";
echo "<td>" . $row['lName'] . "</td>";
echo "<td>" . "View More" . "</td>";
echo "</tr>";
}
echo "</table>";
I have one while loop which displays data from the database. Now I want multiply two values in one row and display the result in the same row, the same way multiply the values and display the result in every row. I am not getting the result. Can anyone help me? I am new to PHP.
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td class='alt'>" . $row['id'] . "</td>";
echo "<td>" . $row['item'] . "</td>";
echo "<td>" . $row['amount'] . "</td>";
$ss=$row['amount'];
echo '<td >'.'<input type="checkbox" name="status" value="" >'.'</td>';
echo '<td >'.'<input type="text" name="qty">'.'</td>';
echo "<td>" . $rr1 . "</td>";
echo "</tr>";
}
From Where you are getting $rr1??
You can have
echo "<td>" . $row['item'] * $row['amount'] . "</td>";
Hope this is what you want...
you can try
printf('amount is %d',$row['item'] * $row['amount']);
reference
Try below :
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td class='alt'>" . $row['id'] . "</td>";
echo "<td>" . $row['item'] . "</td>";
echo "<td>" . $row['amount'] . "</td>";
echo "<td>" .($row['item'] * $row['amount']). "</td>";
echo "</tr>";
}
Change the query as
$result= mysql_query("Select id, item, amount, (item * amount) total
from table_name");
then in while loop
while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td >" . $row['id'] . "</td>";
echo "<td>" . $row['item'] . "</td>";
echo "<td>" . $row['amount'] . "</td>";
echo "<td>" .($row['total'] "</td>";
echo "</tr>";
}
