Hello, please I need help with this, i'm new to PHP I've been trying to figure out for over a week, an I've still found no answers.

I want to send out emails to the subscribers of my eBook. I want to include a link in the email, so when the link is clicked, the subscribers database will be updated.

When this link is clicked, the subscribers are redirected to my homepage.

So i'm having trouble with everything, from start to finish.

This is the code I've written so far:

<body>

<a href="" target="_blank">Click Here To Say YES!</a>

<?php

mysql_connect("localhost", "root", "");
mysql_select_db("rmn");

$sql = mysql_query("UPDATE subscribe SET confirmaton ='YES' WHERE email= [email]");




?>
</body>

Thank you very much!

Check if this works :

$con=mysqli_connect("wwwwwwwwwww.com","any_name","passw","my_db");

// Check connection

if (mysqli_connect_errno())
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}

VB

function update_content($id, $page, $user_date) {

        global $db;

        // define sensible test values

        // create a prepared statement
        $update_stmt = $db->prepare('
            UPDATE
               pages
            SET
               blog_name =?,
               content = ?,
               update_date = ?
            WHERE
               id = ?
        ');

        /* bind parameters for markers */
        $update_stmt->bind_param('ssss', $page['blog_name'], $page['content'], $user_date, $id);

        /* execute query */
        $update_stmt->execute();

        /* close statement */
        $update_stmt->close();
    }

mysql_connect("localhost", "root", "");
mysql_select_db("wrapper");

if(isset($_POST['update'])){
$UpdateQuery = "UPDATE articles_selection SET article = '$_POST[article]' WHERE id ='$_POST[hidden]'";
mysql_query($UpdateQuery);

};

$sql = mysql_query("SELECT * FROM articles_selection");

echo "<table border="1">
<tr>
<th>ID</th>
<th>ARTICLE</th>
</tr>";

while($record = mysql_fetch_array($sql)){
echo "<form action='index.php' method ='post'>";
echo "<tr>";
echo "<td>" . "<input type = 'text' name = 'id' value ="  . $record['id'] . " </td>";
echo "<td>" . "<input type = 'text' name = 'article' value ="  . $record['article'] .    " </td>";
echo "<td>" . "<input type = 'hidden' name = 'hidden' value ="  . $record['id'] . " </td>";
echo "<td>" . "<input class = 'field' type = 'submit' name = 'update' value = 'UPDATE'>" . " </td>";
echo "</tr>";
echo "</form>";
}
echo "</table>";

?>
