我开发了一种将许多东西插入数据库的表单。但是以某种方式，当页面被填满时，它也只插入数据库管理员的user_password。我该如何解决这个问题？

<?php
//include the connection file

require_once('connection.php');
require_once("validation.php");

if( isset($_POST['send']) && (!validateName($_POST['name']) || !validateEmail($_POST['email']) || !validatePasswords($_POST['pass1'], $_POST['pass2']) || !validateContact($_POST['contact']) || !validateAge($_POST['age'])) ):?>
            <div id="error">    
                <ul>
                    <?php if(!validateName($_POST['name'])):?>
                        <li><strong>Invalid Name:</strong> We want names with more than 3 letters.</li>
                    <?php endif?>
                    <?php if(!validateEmail($_POST['email'])):?>
                        <li><strong>Invalid E-mail:</strong> Type a valid e-mail please.</li>
                    <?php endif?>
                    <?php if(!validatePasswords($_POST['pass1'], $_POST['pass2'])):?>
                        <li><strong>Passwords are invalid:</strong> Passwords doesnt match or are invalid!</li>
                    <?php endif?>
                    <?php if(!validateContact($_POST['contact'])):?>
                        <li><strong>Please enter your contact number.</strong></li>
                    <?php endif?>
                    <?php if(!validateAge($_POST['age'])):?>
                        <li><strong>Please enter your age</strong></li>
                    <?php endif?>
                    </ul>
            </div>
        <?php elseif(isset($_POST['send'])):?>
            <div id="error" class="valid">
                <ul>
                <?php $query = "INSERT INTO employee (name, password, email, contact, age, gender, location, skill) ";                           
                $query .= "('$name', '$password', '$email','$contact','$age','$gender','$location','$skill')";
                // run the query
                mysql_query($query);?>
                    <li><strong>Congratulations!</strong> All fields are OK ;)</li>
                </ul>
            </div>
    <?php endif?>
