PHP Enhancing a Simple PHP Application Integrating Validation Errors Escaping Output

stage 1 challenge 1

The PHP file below includes another PHP file that retrieves information from an external source for a directory listing. The page is supposed to display two input fields and a textarea, but it contains some malicious code. Modify the PHP code below to escape the output and display the correct HTML elements on the screen

views_listing_edit.php
    $description = trim($_POST["description"]);
    }
?>
    <form method="post">
        <table>
            <tr>
                <th>
                    <label for="name">Name</label>
                </th>
                <td>
                    <input id="name" name="name" value="<?php if (isset($name)) { echo htmlspecialchars($name); } ?>">
                </td>
            </tr>
            <tr>
                <th>
                    <label for="Link">Link</label>
                </th>
                <td>
                    <input id="link" name="link" value="<?php if (isset($link)) { echo htmlspecialchars($link); } ?>">
                </td>
            </tr>
            <tr>
                <th>
                    <label for="Description">Description</label>
                </th>
                <td>
                    <textarea id="description" name="description"><?php if (isset($description)) { echo htmlspecialchars(description); } ?></textarea>
                </td>

Hi MUZ140045 gumunyu,

The code you have above is different from the challenge itself, you have the correct answer but the final code you should have is the below.

<?php require_once("controllers_listing.php"); ?><html>
<body>

    <h1>Edit Listing</h1>

    <form method="post">
        <table>
            <tr>
                <th>
                    <label for="name">Name</label>
                </th>
                <td>
                    <input id="name" name="name" value="<?php echo htmlspecialchars($listing_name); ?>">
                </td>
            </tr>
            <tr>
                <th>
                    <label for="Link">Link</label>
                </th>
                <td>
                    <input id="link" name="link" value="<?php echo htmlspecialchars($listing_link); ?>">
                </td>
            </tr>
            <tr>
                <th>
                    <label for="Description">Description</label>
                </th>
                <td>
                    <textarea id="description" name="description"><?php echo htmlspecialchars($listing_description); ?></textarea>
                </td>
            </tr>    
        </table>
        <input type="submit" value="Save">
    </form>

</body>
</html>

Hie the correct answer is as follows from Masango Dewheretsoko :

<?php require_once("controllers_listing.php"); ?><html> <body>

<h1>Edit Listing</h1>

<form method="post">
    <table>
        <tr>
            <th>

            <td>
                <input id="name" name="name" value="<?php echo htmlspecialchars($listing_name); ?>">
            </td>
