Let me explain what I want to.
I want to add a value in a list with db add without page change when I input in form
, and click submit
.
but in this code, I must refresh one more time to add, and also added twice a time.
How can I do that?
<?php
$conn = mysqli_connect('127.0.0.1','MYID','MYPASS','MYDB');
$sql = "SELECT * FROM MYTABLE";
$rs = mysqli_query($conn, $sql);
$list = '';
while($row = mysqli_fetch_array($rs)) {
$list = $list."<li><a href=\"index.php?id={$row['id']}\">{$row['title']}</a></li>";
}
$article = array(
'title' => 'Welcome!',
'description' => 'Hello, Web!'
);
if (isset($_GET['id'])){
$filtered_id = mysqli_real_escape_string($conn, $_GET['id']);
$sql = "SELECT * FROM topic WHERE id={$filtered_id}";
$rs = mysqli_query($conn, $sql);
$row = mysqli_fetch_array($rs);
$article['title'] = $row['title'];
$article['description'] = $row['description'];
}
if ($_POST['title'] != null){
$sql_in = "INSERT INTO topic (title, description, created) VALUES ('{$_POST['title']}', '{$_POST['description']}', NOW())";
$rs_in = mysqli_query($conn, $sql_in);
if ($rs_in === false) {
$msg = mysqli_error($conn);
} else {
$msg = 'Success.';
}
} else {
$msg = 'Fill in';
}
?>
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>WEB</title>
</head>
<body>
<h1><a href="index.php">WEB</a></h1>
<ol>
<?=$list?>
</ol>
<details>
<summary>Create</summary>
<form action="./index.php" method="POST">
<p><input type="txt" name="title" placeholder="title"></p>
<p><textarea name="description" placeholder="description"></textarea></p>
<p><input type="submit"></p>
<p><?=$msg?></p>
</form>
</details>
</body>
</html>
<h2><?=$article['title']?></h2>
<?=$article['description']?>
</body>
</html>
In php realtime isn't a thing but there is a workaround you can use events services like pusher https://pusher.com/docs and receive the events in client side instantly .
there other website offers this so do your search before choosing them also you can always build your event server in node.js , c# , go
