Я пытаюсь вставить некоторую информацию со своей страницы регистрации. Я делаю все функции с моделью 'MVC'. код:
Страница регистрации:
<main>
<div id="mainWrraper">
<p id="error"></p>
<?php echo form_open('login_controller/insertData'); ?>
<fieldset>
<legend>Registration:</legend>
<div class="inputWrapper"><label>First name: </label><input id="First_name" class="formInput" type="text" name="First_name"></div>
<div class="inputWrapper"><label>Last name: </label><input id="Last_name" class="formInput" type="text" name="Last_name"></div>
<div class="inputWrapper"><label>Email: </label><input id="Email" class="formInput" type="text" name="Email"></div>
<div class="inputWrapper"><label>Username: </label><input id="Username" class="formInput" type="text" name="Username"></div>
<div class="inputWrapper"><label>Password: </label><input id="Password" class="formInput" type="password" name="Password"></div>
<div class="inputWrapper"><label>Confirm Password: </label><input id="Confirm_password" class="formInput" type="password" name="Confirm_password"></div>
<div class="inputWrapper"><label>Year Of Birth: </label><input id="Year_Of_Birth" class="formInput" type="text" name="Year_Of_Birth"></div>
<!--<div class="inputWrapper"><label>Date Of Birth: </label><input id="Date_B" class="formInput" type="date" name="Date_B"></div>-->
<div class="inputWrapper"><label> Location:</label><select id="Location" name="Location">
<option value="Central">Central</option>
<option value="South">South</option>
<option value="North">North</option>
</select></div>
<div class="inputWrapper"><label> Gender:</label><select id="Gender" name="Gender">
<option value="Women">Women</option>
<option value="Men">Men</option>
</select></div>
<div class="inputWrapper"><input id="register" type="button" value="register" name="submit">
</fieldset>
</form>
</div>
</main>
<script>
$("#register").click(function() {
var First_name = $("#First_name").val();
var Last_name = $("#Last_name").val();
var Email = $("#Email").val();

success: function(data) {
if (data === "1") {

window.location.href = "<?php echo site_url('login_controller/login');?>";
} else {
$("#error").html(data);
}
}
});
});
</script>
Login_Controller:
<?php

Login_Model:

$error=NULL;
if (!$this->db->insert('users', $data)){
$error=$this->db->error();
}
echo "Test Message";
return $error;
}
}
Проблема в том, что когда я нажимаю «Зарегистрироваться» на странице регистрации. когда я щелкаю по нему, я прыгаю в строку 62 (код страницы регистра) alert('Something is wrong'); и в DevTools показывается мне: 
Моя база данных выглядит так: 
и в Интернете это выглядит так (здесь показывается предупреждение): 
Надеюсь, я объясню себя хорошо, я просто хочу вставить свои данные в базу данных. большое спасибо !
РЕДАКТИРОВАТЬ # 1: Я думаю, что проблема заключается в соединении между контроллером и моделью. похоже, он не распознает функцию модели (и файл).
