How can the issue of missing parameters in the tbl_get_field.php file be resolved?

Issue: The missing parameters in the tbl_get_field.php file can be resolved by checking if the required parameters are set before attempting to use them in the code. This can be done by using the isset() function to verify the existence of the parameters before proceeding with the database query. 

// Check if the required parameters are set
if(isset($_GET['table_name']) && isset($_GET['field_name'])) {
    // Proceed with the database query
    $table_name = $_GET['table_name'];
    $field_name = $_GET['field_name'];
    
    // Your database query code here
} else {
    // Handle the case where parameters are missing
    echo "Missing parameters: table_name and field_name are required.";
}
