สมมุติว่าผมต้องการเปลี่ยนสีตัวอักษร เช่น ถ้า ค่าในตารางช่อง Temperature มากกว่า 25 ให้ข้อมูลช่องนั้นเป็นตัวอักษรสีแดง และ ให้ถ้าน้อยกว่า 25 ให้เป็นสีดำ ไม่ทราบว่าพอจะทำได้หรือเปล่าครับ และ ทำยังไง (ตารางผมเป็นแบบ Dynamic Table ดึงค่าจากฐานข้อมูลนะครับ)
Code (PHP)
<?php require_once('../../../Connections/TempH.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")
{
if (PHP_VERSION < 6) {
$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
}
$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);
switch ($theType) {
case "text":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "long":
case "int":
$theValue = ($theValue != "") ? intval($theValue) : "NULL";
break;
case "double":
$theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
break;
case "date":
$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
break;
case "defined":
$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
break;
}
return $theValue;
}
}
$maxRows_Dataformdatabase = 24;
$pageNum_Dataformdatabase = 2;
if (isset($_GET['pageNum_Dataformdatabase'])) {
$pageNum_Dataformdatabase = $_GET['pageNum_Dataformdatabase'];
}
$startRow_Dataformdatabase = $pageNum_Dataformdatabase * $maxRows_Dataformdatabase;
mysql_select_db($database_TempH, $TempH);
$query_Dataformdatabase = "SELECT * FROM temp";
$query_limit_Dataformdatabase = sprintf("%s LIMIT %d, %d", $query_Dataformdatabase, $startRow_Dataformdatabase, $maxRows_Dataformdatabase);
$Dataformdatabase = mysql_query($query_limit_Dataformdatabase, $TempH) or die(mysql_error());
$row_Dataformdatabase = mysql_fetch_assoc($Dataformdatabase);
if (isset($_GET['totalRows_Dataformdatabase'])) {
$totalRows_Dataformdatabase = $_GET['totalRows_Dataformdatabase'];
} else {
$all_Dataformdatabase = mysql_query($query_Dataformdatabase);
$totalRows_Dataformdatabase = mysql_num_rows($all_Dataformdatabase);
}
$totalPages_Dataformdatabase = ceil($totalRows_Dataformdatabase/$maxRows_Dataformdatabase)-1;

<td bgcolor="#E0FFFF"><?php echo $row_Dataformdatabase['Temperature']; ?></td>
เปลี่ยนเป็น
<td bgcolor="<?php $row_Dataformdatabase['Temperature'] >25 ? 'red' : 'black'; ?>"><?php echo $row_Dataformdatabase['Temperature']; ?></td>

<td bgcolor="<?php echo $row_Dataformdatabase['Temperature'] >25 ? 'red' : 'black'; ?>"><?php echo $row_Dataformdatabase['Temperature']; ?></td>
แก้ไขตกหล่นให้ครับ
ปล. แต่ผมจะใช้ <?=($row_Dataformdatabase['Temperature'] >25 ? 'red' : 'black')?>
ซึ่งรูปแบบ <?=$var?> เป็นรูปแบบหนึ่งในการใช้่งานของ tag php ในการ echo ข้อมูล และเป็นรูปแบบมาตรฐานของ PHP
ไม่ใช่ short tag เฃ่น <? echo 'abc'; ?>
เมื่อคุณ ปิด short_tag แล้ว <?=$var?> ก็ยังใช้งานได้อยู๋
