→ knives:這很正常阿，沒有顯示$time_end['timestamp']才不正常 08/21 23:13
→ ileadu:begin的時間 早就被洗掉了.. 08/22 02:16
→ beavis1103:那請問應該怎麼改才能兩個時間都顯示 08/22 13:47
→ knives:從一開始你的設計觀念就錯了，無關php阿 08/22 14:23

我是個php的初學者~以下是我的程式碼~
<html>
<head>
<title>Collect training data</title>
</head>
<body>
Input location:
<form action="collect_training_data.php" method="post">
<input type="text" name="input" size="10">
<input type="submit" name="start" value="Start" size="5">
<input type="submit" name="stop" value="Stop" size="5">
</form>
<br><a href='collect_training_data.php'>Redo</a><br>
</body>
</html>
(以下是php的部份)
<?php
$sql_time="select now() as timestamp";
if($_POST['start'] && $input_location!=""){
echo "start to collect training data which location is : ".$input_location;
$result=@mysql_query($sql_time);
$time_begin= mysql_fetch_array($result);
echo "<br>begin time : ".$time_begin['timestamp'];
}
if($_POST['stop']){
$result=@mysql_query($sql_time);
$time_end= mysql_fetch_array($result);
echo "<br>end time: ".$time_end['timestamp'];
echo "<br> Time between {$time_begin['timestamp']} and {$time_end['timestamp']};
}
?>
我的疑問是 按下start按鈕再按下stop按鈕後只會顯示 $time_end['timestamp']的時間
究竟是哪邊的問題呢??
