table.php更新基於ID SQL表的多個行如何使用一個按鈕
<?php
include('../connections/conn.php');
include('../php/login.php');
$sql = "SELECT * FROM person";
$records = mysqli_query($conn, $sql)
?>
<html>
<head>
<title>Table</title>
</head>
<body>
<table>
<tr>
<th>Name</th>
<th>Age</th>
<th>Salary</th>
</tr>
<?php
while($row = mysqli_fetch_array($records)){
$name = $row['Name'];
$age = $row['Age'];
$salary = $row['Salary'];
$id = $row['id'];
echo "<tr><form action=update.php method=post>";
echo "<td><input type=text name=pname value='$name'></td>";
echo "<td><input type=text name=age value='$age'></td>";
echo "<td><input type=text name=salary value='$salary'></td>";
echo "<input type=hidden name=id value='$id'></td>";
echo "<td><input type=submit>";
echo "</form></tr>";
}
?>
</table>
</body>
</html>
(在這部分代碼顯示錶和它的值)
Update.php
<?php
include('../connections/conn.php');
include('../php/login.php');
$sql = "UPDATE person SET
Name='$_POST[pname]',Age='$_POST[age]',Salary='$_POST[salary]' WHERE
id='$_POST[id]'";
if(mysqli_query($conn, $sql)){
header("refresh:1 url=table.php");
}
else{
echo"Not Update";
}
$records = mysqli_query($conn, $sql)
?>
(這部分是用於更新表)
我已經得到了代碼更新表全光照的內容g按鈕,但我想只有一個按鈕,將更新整個表。此刻,我每行使用一個按鈕來更新該特定行。
