应该从数据库中获取数据，并显示在表格上。每条记录上都有一个文本框，可以在其中插入收据编号并提交。提交后，收据编号应插入到该记录的数据库中，并且页面重新加载，显示插入的记录而不是文本字段。我不确定我做错了什么，因为页面加载到空白页面。
$sql = "SELECT * FROM customer";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo " <table><tr><th>ID</th><th>Name</th>
<th>Amount</th><th>TransactionID</th><th>Mobile Number</th>
<th>Time Paid</th><th>Account</th>
<th>Receipt Number</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<tr><td>" . $row["id"]. "</td>
<td>" . $row["name"]. "</td><td>" . $row["amount"]. "</td>
<td>" . $row["trans_id"]. "</td><td>" . $row["msisdn"]. "</td>
<td>" . $row["time_paid"]. "</td>
<td>" . $row["status"]. "</td>
<td><form action= 'receipt.php' method='post'>
<input type ='text' name='receipt'>
<input type ='hidden' name='hidden' value='".$row["receipt"]."'>
<input type='submit' name='submit' value='submit'></td></form></tr>";
}
echo "</table> ";
// receipt.php
if(isset($_POST['submit']))
{
//connection
$sql = "INSERT INTO customer (receipt, date_entered) VALUES ('" . $_POST['receipt'] . "','NOW()')";
if ($conn->query($sql) === TRUE) {
// echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
}
$conn->close();
header('Location: http://localhost/com/payf.php');
}
else {
echo "Please Enter the Receipt Number";
header('Location: http://localhost/com/payf.php');
}
最佳答案
在您的receipt.php文件中；
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="utf-8">
<title>title</title>
</head>
<body>
<?php
//NEW
$servername = "example.com";
$username = "username";
$password = "password";
$dbname = "database";
// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
die("Connection failed: " . $conn->connect_error);
}
//NEW
$sql = "SELECT * FROM customer";
$result = $conn->query($sql);
if ($result->num_rows > 0) {
echo " <table><tr><th>ID</th><th>Name</th>
<th>Amount</th><th>TransactionID</th><th>Mobile Number</th>
<th>Time Paid</th><th>Account</th>
<th>Receipt Number</th></tr>";
// output data of each row
while($row = $result->fetch_assoc()) {
echo "<tr><td>" . $row["id"]. "</td>
<td>" . $row["name"]. "</td><td>" . $row["amount"]. "</td>
<td>" . $row["trans_id"]. "</td><td>" . $row["msisdn"]. "</td>
<td>" . $row["time_paid"]. "</td>
<td>" . $row["status"]. "</td>
<td><form action= 'receipt.php' method='post'>
<input type ='text' name='receipt'>
<input type ='hidden' name='tid' value='".$row["id"]."'>
<input type='submit' name='submit' value='submit'></td></form></tr>";
}
echo "</table>";
} else { //FIX ************
echo "no results";
}
// receipt.php
if(isset($_POST['submit'])) {
//connection
//$sql = "INSERT INTO customer (receipt, date_entered) VALUES ('".$_POST['receipt']."',NOW())"; //FIX ***
$sql = "UPDATE customer SET `receipt` = '".$_POST['receipt']."', `date_entered` = NOW() WHERE `id` = '".$_POST['tid']."'"; //NEW
if ($conn->query($sql) === TRUE) {
// echo "New record created successfully";
} else {
echo "Error: " . $sql . "<br>" . $conn->error;
exit(); //NEW
}
$conn->close();
header("Location: http://{$servername}/project/payf.php"); //FIX ************
} else {
//echo "Please Enter the Receipt Number"; //FIX ************ this goes into payf.php
//header("Location: http://{$servername}/project/payf.php");//FIX ******** this redirects when main table is dispayed
}
echo "</body></html>";
?>
</body></html>
根据注释，此代码中存在许多问题
- 在 header 重定向之前回显
- 没有 $conn 设置
- 表格显示时重定向
- 缺少右括号
- 不正确的 SQL 语法(引号)
- 插入而不是更新
- HTML 质量较差
- 结构不良

此代码可以正常运行并经过测试。 快乐编码!
