What are the potential reasons for a field not being saved in a MySQL database when using the tinyMCE editor?

The potential reasons for a field not being saved in a MySQL database when using the tinyMCE editor could be due to the content exceeding the field's character limit, special characters causing issues with the SQL query, or improper handling of the data before insertion. To solve this issue, make sure to properly sanitize and escape the content before inserting it into the database, check the field's character limit, and ensure that the SQL query is correctly formatted.

// Assuming $content contains the data from the tinyMCE editor
$content = mysqli_real_escape_string($connection, $_POST['content']); // Sanitize and escape the content

// Check if content exceeds the field's character limit
if(strlen($content) > 255) {
    echo "Content exceeds character limit";
} else {
    // Insert the content into the database
    $query = "INSERT INTO table_name (content) VALUES ('$content')";
    mysqli_query($connection, $query);
}
