我是 PHP 和 MySQL 新手。我有一个 HTML 表和表单，可将输入的数据提交到 MySQL，但不会在 HTML 表中显示 MySQL 数据。这是供引用的图片:https://i.imgur.com/OEDd6Px.png 。如果可能的话，我希望提交的数据在提交时显示，但无法找到解决方案。提前致谢。
<?php
$host = "localhost";
$user = "root";
$pass = "";
$db = "test";
$conn = mysqli_connect($host, $user, $pass, $db);
if (!$conn) {
die ('Failed to connect to MySQL: ' . mysqli_connect_error());
}
if(isset($_POST["asin"]))
{
$asin = $_POST["asin"];
$category = $_POST["category"];
$submit = "INSERT INTO `user_input`(`id`, `asin`, `category`, `date`) VALUES (NULL, '$asin', '$category', CURRENT_DATE())";
$sql = mysqli_query($conn, $submit);
if (!$sql) {
die ('SQL Error: ' . mysqli_error($conn));
}
$display = "SELECT * FROM user_input";
$result = mysqli_query($conn, $display);
if (!$result) {
die ('SQL Error: ' . mysqli_error($conn));
}
}
?>

最佳答案
尝试写
$display = "SELECT * FROM user_input";
$result = mysqli_query($conn, $display);
if (!$result) {
die ('SQL Error: ' . mysqli_error($conn));
}
挡住条件的一侧。
关于php - 有人能解释一下为什么我的 MySQL 表数据没有显示吗？，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/50397284/
