任何人都可以帮我处理我的案例......为什么无法更新我的数据 我是php和mysql的新手。我不知道该怎么做。我坚持这个。 请参考示例。该怎么办？
PHP
<?php require_once("include/connection.php")?>
<?php
$group_id = (int)$_GET['id'];
if(isset($_POST['submit'])) {
$hour_start = $_POST['hour_start'];
$minute_start = $_POST['minute_start'];
$time_start = $hour_start . ":" . $minute_start;
$hour_finish = $_POST['hour_finish'];
$minute_finish = $_POST['minute_finish'];
$time_finish = $hour_finish . ":" . $minute_finish;
$day_start = $_POST['day_start'];
$day_finish = $_POST['day_finish'];
$query2 = "UPDATE test_group_details SET
time_start = '{$time_start}',
time_finish = '{$time_finish}',
day_start = '{$day_start}',
day_finish = '{$day_finish}',
hour_start = '{$hour_start}',
minute_start = '{$minute_start}',
hour_finish = '{$hour_finish}',
minute_finish = '{$minute_finish}'
WHERE id = '{$details_id }'
";
$result2 = mysql_query($query2, $connection);
/* } */
}
?>
这是显示数据的地方......还有要更新的表格.. 的 HTML
<div class="nav_left">
<form name="frm" action="#" method="post" onsubmit="return frm_onsubmit();">
<table>
<tbody>
<tr>
<?php
$edit_query2 = "SELECT * FROM test_group_details WHERE group_id = '{$group_id}' ";
$rs2 = mysql_query($edit_query2,$connection);
while($row2 = mysql_fetch_array($rs2)):
?>
<td colspan="2"><h5><?php echo "\n\n" . $row2['time_start'] . " - " . $row2['time_finish'] . " [" . $row2['day_start'] . " - " . $row2['day_finish'] . "] ";?><hr></h5>

请帮助我们......是他们的一种方式......？
答案 0 :(得分：0)
您在代码中定义了哪些$details_id？
我看不到它。我只看到$group_id，无论如何都是单号。
db中的行是否与group_id相同？
表格中该字段的名称是什么？
