我有表格并且连接了MySQL，所以每当我填写时它都会显示在mySQL中。下一步是在我的index.php 中有一个目录，即我所拥有的。但现在，当我想按删除按钮时，它会显示总页。
这是我的index.php
<?php
if (isset($_POST["submit"])) {
$ime = $_POST["ime"];
$prezime = $_POST["prezime"];
$pozicija = $_POST["pozicija"];
if (!empty($ime) && !empty($prezime) && !empty($pozicija)) {
/*host, username, password, dbname*/
$link = mysqli_connect("localhost", "root", "", "forma");
// Check connection
if ($link === false) {
die("ERROR: Could not connect. " . mysqli_connect_error());
}
// Attempt insert query execution
$sql = "INSERT INTO forma (Ime, Prezime, Poziicija) VALUES ('$ime', '$prezime' , '$pozicija')";
if (mysqli_query($link, $sql)) {
echo "Records inserted successfully." . "<br>";
} else {
echo "ERROR: Could not able to execute $sql. " . mysqli_error($link);
}
$podaci = "SELECT * FROM forma";
$rezultat = mysqli_query($link, $podaci);
if (!$rezultat) {
die(mysqli_error($link));
}
if (mysqli_num_rows($rezultat) > 0) {
foreach ($rezultat as $rez) {
foreach ($rez as $key => $value) {
echo ucfirst($key) . ": " . $value . "<br>";
}
}
} ?>

<?php
$con = mysqli_connect("localhost", "root", "", "forma");
$query = "SELECT * FROM forma";
$query_run = mysqli_query($con, $query);
if (mysqli_num_rows($query_run) > 0) {
foreach ($query_run as $row) {
?>
<tr>

<?php
}
} else {
?>

</tr>
<?php
}
?>
</tbody>
</table>
</form>
</body>
</html>
<?php
// Close connection
mysqli_close($link);
}
}
这是我的 insert.php，其中只是表单
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Form</title>
</head>
<body>
<form action="index.php" method="post">
<label for="ime">Ime</label>
<input type="text" name="ime" required><br>
<label for="prezime">Prezime</label>
<input type="text" name="prezime" required><br>
<label for="pozicija">Pozicija</label>
<input type="text" name="pozicija" required><br>
<button type="submit" name="submit">Submit</button><br>
</form>
</body>
</html>
这是我的delete.php
<?php
//delete
session_start();
$con = mysqli_connect("localhost", "root", "", "forma");
if (isset($_POST['delete'])) {
$all_id = $_POST['delete_id'];
$extract_id = implode(',', $all_id);
//echo $extract_id;
$query = "DELETE FROM forma WHERE id IN($extract_id) ";
$query_run = mysqli_query($con, $query);
if ($query_run) {
$_SESSION['status'] = "Multiple Data Deleted Successfully";
header("Location: index.php");
} else {
$_SESSION['status'] = "Multiple Data Not Deleted";
header("Location: index.php");
}
}
所以我只是想了解我的下一步是什么，或者我做错了什么。谢谢您的帮助。
在您的删除页面中，我认为您的查询中缺少逗号：
$query = "从格式中删除 WHERE id IN ($extract_id)";
