I'm trying to get a total amount for a list of sales using an SQL statement in PHP, I already have the SQL statement but I'm not sure how to get the results of the query onto the webpage, I'm planning on putting it in the second PHP tag after the table.
$result = mysqli_query($dbc,$query);
echo "<p>Customers on file = " .mysqli_num_rows($result). "</p>";
while ($row = mysqli_fetch_array($result)) {
echo "<tr>";
echo "<td>" .$row[0]. "</td>";
echo "<td>" .$row['last_name']. "</td>";
echo "<td>" .$row['Customer_id']. "</td>";
echo "<td>" .$row['3']. "</td>";
echo "<td>" .$row['4']. ", " .$row['5']. " " .$row['6']. "</td>";
echo "<td align='right'>$" .number_format($row['credit_limit']). "</td>";
echo "<td align='right'>" .$row['salescnt']. "</td>";
echo "<td align='right'>" .number_format($row['salestot'],2). "</td>";
echo "<tr>";
}
?>
</table>
<?php
$query = "SELECT sum(total) AS totsales FROM sales_order";
echo "<p>Total of all sales = " </p>" ?>
</body>
</html>

I need to retrieve the color hex code stored in a database and display it as seen on screen within a table cell. i'm trying to find a way to convert the hex code the db query returns for that specific table cell into the actual color that the hex denotes. Here's my code...
<?php
// Include config file
require_once "config.php";
$pdo = new PDO($dsn, $username, $password, $options);
// Attempt select query execution
$sql = "SELECT * FROM sales";
if($result = $pdo->query($sql)){
if($result->rowCount() > 0){
echo "<table class='table table-bordered table-striped'>";
echo "<thead>";
echo "<tr>";
echo "<th>S/N</th>";
echo "<th>Transaction Date</th>";
echo "<th>Customer Name</th>";
echo "<th>Address</th>";
echo "<th>Phone Number</th>";
echo "<th>Vehicle Model</th>";
echo "<th>Vehicle Chassis Number</th>";
echo "<th>Vehicle Registration Number</th>";
echo "<th>Vehicle Color</th>";
echo "<th>Amount Paid</th>";
echo "<th>Advance</th>";
echo "<th>Balance</th>";
echo "<th>Balance Due Date</th>";
echo "<th>Paid To</th>";
echo "</tr>";
echo "</thead>";
echo "<tbody>";
while($row = $result->fetch()){
echo "<tr>";
echo "<td>" . $row['id'] . "</td>";
echo "<td>" . $row['transactiondate'] . "</td>";
echo "<td>" . $row['customername'] . "</td>";
echo "<td>" . $row['address'] . "</td>";
echo "<td>" . $row['phonenumber'] . "</td>";
echo "<td>" . $row['vehiclemodel'] . "</td>";
echo "<td>" . $row['vehiclechassisnumber'] . "</td>";
echo "<td>" . $row['vehicleregistrationnumber'] . "</td>";
echo "<td>" . $row['vehiclecolor'] . "</td>";
echo "<td>" . $row['amountpaid'] . "</td>";
echo "<td>" . $row['advance'] . "</td>";
echo "<td>" . $row['balance'] . "</td>";
echo "<td>" . $row['balancedate'] . "</td>";
echo "<td>" . $row['paidto'] . "</td>";
echo "<td>";
echo "</tr>";
}
echo "</tbody>";
echo "</table>";
// Free result set
unset($result);
} else{
echo "<p class='lead'><em>No records were found.</em></p>";
}
} else{
echo "ERROR: Could not able to execute $sql. " . $mysqli->error;
}
// Close connection
unset($pdo);
?>
It is a bit unclear about where you wish to use the colour but I'm assuming it is here. And also my assumption is the retrieved value for vehiclecolor column is a HEX value
echo "<td>" . $row['vehiclecolor'] . "</td>";
You can use tag property 'background-color' for this.
$temp = $row['vehiclecolor'];
echo "<td style='background-color:" . $temp ."'></td>";
Pretty self-explanatory I guess. String concatenation.
Two questions in one:
First question, mainly about presentation:
I'm echo-ing the following code which should create a table. The table should have a single column, but it's being rendered with the elements above the image as a single line. can anyone see why?
<?php
$sql = "SELECT * FROM catdata WHERE featured='yes' LIMIT 2";
if($result = mysqli_query($link, $sql)){
if(mysqli_num_rows($result) > 0){
echo "<table>";
while($row = mysqli_fetch_array($result)){
echo "<tr>";
echo "<td>" . $row['manufacturer'] . "</td>";
echo "</tr";
echo "<tr>";
echo "<td>" . $row['title'] . "</td>";
echo "</tr";
echo "<tr>";
echo "<td><img src=\"6.diesel.png\"></td>";
echo "</tr>";
echo "<tr>";
echo "<td>" . $row['size'] . "l</td>";
echo "</tr>";
echo "<tr>";
echo "<td>" . $row['mileage'] . "</td>";
echo "</tr>";
echo "<tr>";
echo "<td>" . $row['fitsmodel'] . "</td>";
echo "</tr>";
echo "<tr class=\"tablePriceBlock\">";
echo "<td>£" . $row['pricefitted'] . "</td>";
echo "</tr>";
echo "<tr>";
echo "<td>£" . $row['pricedel'] . "</td>";
echo "</tr>";
}
echo "</table>";
// Free result set
mysqli_free_result($result);
} else {
echo "No records matching your query were found.";
}
} else{
echo "ERROR: Unable to execute $sql. " . mysqli_error($link);
}
?>
Question 2:
Can I show the second result in a second column, or as a separate table? Also, is it possible to access the $result elements like say, $[manufacturer][1]?
Always look at the emitted source your code generates by either "View Source" or using a tool like curl. You'll find this mistake:
echo "</tr";
You're missing a >.
Many people who write HTML have browser plugins that can link through to an HTML validator to ensure they've got the correct syntax. You may want to find and install one of these.
To generate the second result is a separate table follow the following code.
echo "<table>";
$count = 1;
while($row = mysqli_fetch_array($result)){
if($count == 2){
echo "<table>";
echo "<tr>";
echo "<td>put your code here</td>";
echo "</tr>"
echo </table>
}else{
echo "<tr>";
echo "<td>" . $row['manufacturer'] . "</td>";
echo "</tr";
echo "<tr>";
echo "<td>" . $row['title'] . "</td>";
echo "</tr";
echo "<tr>";
echo "<td><img src=\"6.diesel.png\"></td>";
echo "</tr>";
echo "<tr>";
echo "<td>" . $row['size'] . "l</td>";
echo "</tr>";
echo "<tr>";
echo "<td>" . $row['mileage'] . "</td>";
echo "</tr>";
echo "<tr>";
echo "<td>" . $row['fitsmodel'] . "</td>";
echo "</tr>";
echo "<tr class=\"tablePriceBlock\">";
echo "<td>£" . $row['pricefitted'] . "</td>";
echo "</tr>";
echo "<tr>";
echo "<td>£" . $row['pricedel'] . "</td>";
echo "</tr>";
}
$count ++;
}
echo "</table>";
As you are limiting your query to only two record so this method is not bad for that and hope this will help.
i'm trying to do a table with php which takes the data from my database and build's the table im html but despite my while loop , only the 1st row is getting into the table. If i change the while loop before the
echo "<table border='1' cellpadding='2' cellspacing='2'";
I get all of them but in 3 tables.
What's wrong with the code ?
<?php
require 'connect.php';
$query = $link->query("SELECT * FROM fornecedor");
echo "Fornecedores";
echo "<table border='1' cellpadding='2' cellspacing='2'";
echo "<tr>
<td>Nome</td>
<td>NIF</td>
<td>Cidade</td>
<td>Rua</td>
<td>NrPorta</td>
<td>Website</td>
<td>email</td>
</tr>";
while ($row = mysqli_fetch_array($query)) {
echo "<tr>";
echo "<td>" . $row["Nome"] . "</td>";
echo "<td>" . $row["NIF"] . "</td>";
echo "<td>" . $row["Cidade"] . "</td>";
echo "<td>" . $row["Rua"] . "</td>";
echo "<td>" . $row["NrPorta"] . "</td>";
echo "<td>" . $row["Website"] . "</td>";
echo "<td>" . $row["Email"] . "</td>";
echo "</tr>";
echo "</table>";
};
?>
Move echo "</table>"; out of the while loop-
....
while(){
.....
// don't close the table tag here
}
echo "</table>";
For each row you are adding the closing </table> tag which should not be like that.
echo "</table>"; code must be out of the while loop. It must be written once only.
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>" . $row['sum'] . "</td>";
}
I'm not sure, since your question is poorly written. But I think you just need to do this to get the values:
SELECT studentid,hw1,hw2,hw3,SUM(hw1+hw2+hw3)
I have one while loop which displays data from the database. Now I want multiply two values in one row and display the result in the same row, the same way multiply the values and display the result in every row. I am not getting the result. Can anyone help me? I am new to PHP.
while($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>";
}
