无法在MySQL中插入多行？

Question

Here is my PHP code:

$html = $_POST['html'];
$username   = $_POST['username'];
$connection = new mysqli('host', 'username', 'password', 'database');
$username   = $connection->real_escape_string($username);
$html       = $connection->real_escape_string($html);
$connection->query("INSERT INTO savedarticles (username, article) VALUES ('$username', '$html')");

Here is my AJAX code:

$.ajax({
  type: "POST",
  url: 'savedarticle.php',
  data: {
    html: innerHTML,
    username: '<?php echo $_SESSION['user']; ?>'    
  }
}); 

$html has a unique value every time. Let's say I have two values:

1. username = alpha , html = bla, bla class="bla"
2. username = alpha , html = more bla class="bla"

By class I want to signify there are double quotes in the HTML but I am escaping them. If I click on any one of these two the value are stored in database but no subsequent values are stored. If I click on 1 first it will be saved and later clicking on 2 won't have any effect. If I click on 2 first it will be saved and later clicking on 1 won't have any effect. In case it matters I have another table with same column name username . Also my table savedarticles has an Id column with int values, username column with type varchar(255) and article column with type text .

I have edited your code. Please have a look and try .

<?php
$html = $_POST['html'];
$username   = $_POST['username'];
$connection = mysqli_connect('host', 'username', 'password', 'database');
$username   = $connection->real_escape_string($username);
$html       = $connection->real_escape_string($html);
$connection->query("INSERT INTO savedarticles (username, article) VALUES ('".$username."', '".$html."')");

?>
