在home_v.php页面中单击“添加学生”按钮，打开另一个视图页面user_v.php
问题描述：

<center><h1>Welcome Students!</h1><br><br></center>

<h2>List of Students in system are : </h2>
<div id="list">
<table class='looks'>
<tr><th>Student Name</th>
<th></th><th></th><th></th></tr>
<?php
foreach ($list->result() as $row)
{
echo "<tr>";
echo "<td style='width:30%'>".$row->name."</td>";
echo "<td><input type='submit' value='Add Student' style='float:left'
onclick="site_url().'/user_c/add'"></td>";
echo '<td><input type="submit" value="Update Student"

echo '<td><input type="submit" value="Delete Student"
style="float:left"></td>';
echo "</tr>";
}
?>
</table>
</div>
</body>
</html>
The foreach loop is executed and the values of student are displayed on the home_v.php page. Besides the names of these students, I have added a button (Add Student).On clicking this button I want to open another view page user_v.php, for which I have used onclick tag in the button. But it is not working and I get the error attached below. Kindly help as what is the mistake I am making.
//controller
function add()
{
$this->load->view('user_v');
}

You are making mistake in concatenating PHP and HTML data. And to make it work on the click do following changes:
echo "<td><input type='submit' value='Add Student' style='float:left'
onclick=window.location='". site_url("user_c/add")."'></td>";
