Question

我创建了一个包含搜索功能的表，该表显示了我数据库中的信息。我已经在每行的最后2列上创建了一个编辑和删除链接。 问题是，当我点击编辑它时，不会将我引导到我创建的表单并将其链接到，对于删除链接，它根本不会删除。我将包含视图的代码，如果您需要我再显示代码，我会这样做。

<table  align="center">
<tr>
    <th>Voter #</th>
    <th>First Name</th>
    <th>Last Name</th>
    <th>Middle</th>
    <th>Home #</th>
    <th>Street</th>
    <th>Apt</th>
    <th>Zip</th>
    <th>DOB</th>
    <th>District</th>
    <th>Edit</th>
    <th>Delete</th>

</tr>
<?php 
foreach($query as $voter){
    $voter_id = $voter['voterNum'];
    ?>
<tr align="center">
    <td><?php echo $voter['voterNum'] ?></td>
    <td><?php echo $voter['firstName'] ?></td>
    <td><?php echo $voter['lastName'] ?></td>
    <td><?php echo $voter['midInitial'] ?></td>
    <td><?php echo $voter['homeNum'] ?></td>
    <td><?php echo $voter['street'] ?></td>
    <td><?php echo $voter['apt'] ?></td>
    <td><?php echo $voter['zip'] ?></td>
    <td><?php echo $voter['dob'] ?></td>
    <td><?php echo $voter['district'] ?></td>
    <td><a href= "<?php echo base_url("reg/edit_voter/");?><?php echo $voter_id ?>">Edit</a></td>
    <td><?php echo anchor('reg/delete_voter'.$voter_id, 'Delete', 
            array('onClick' => "return confirm('Are you sure you want to delete?')"));
    ?>
    </td>
</tr>
<?php
}
?>
</table>

Answer 1

为什么要混合使用base_url（）和anchor（）？只需使用anchor（）。

<td><?php echo anchor("reg/edit_voter/{$voter_id}", 'Edit') ?></td>


<td><?php echo anchor('reg/delete_voter/'.$voter_id, 'Delete', 
            array('onClick' => "return confirm('Are you sure you want to delete?')"));
    ?>
</td>

我认为你的删除链接缺少一个尾部斜杠。

在Codeigniter中编辑和删除
