Refresh one variable every second
I want to refresh two variables named profittext and sumtext which will be
refreshed and echoed in the following places every few seconds. I know
AJAX is needed to do this but how do i actually make it work ? The only
way i found out was to refresh the content of the whole file. is there any
way to refresh specific variables? Any answers will be greatly appreciated
. Thank you very very much.
<table>
if($profitandloss<$zero) {
$profitText = "<div style=\"color: red;\">$profitandloss</div>";
} elseif ($profitandloss>$zero) {
$profitText = "<div style=\"color: green;\">$profitandloss</div>";
}
// for profit and loss counting
$sum+= $profitandloss;
//
echo "<tr><td>" . $row['trade_id'] .
"</td><td>" . $row['selection'] .
"</td><td>" . $row['date'] .
"</td><td>" . $row['type'] .
"</td><td>" . $row['size'] .
"</td><td>" . $row['bidprice'] .
"</td><td>" . $row['offerprice'] .
"</td><td>" . $row['stoploss'] .
"</td><td>" . $row['takeprofit'] .
"</td><td>" . $profitText .
"</td><td><a href ='delete.php?id=".
$row['trade_id']."'>X</a>
</td></tr>";
$profitandloss=0;
if($sum<$zero) {
$sumText = "<div style=\"color: red;\">$sum</div>";
} elseif ($sum>$zero) {
$sumText = "<div style=\"color: green;\">$sum</div>";
}
}
echo "</table><br>";
?>
<!DOCTYPE html>
<html>
<table style="border:1px solid black;">
<tr>
<th style="border:1px solid black;">Profit/Loss</th>
</tr>
<tr>
<td style="border:1px solid black;"><?php echo $sumText ;?></td>
</tr>
</table>
</html>
