我正在用用户照片创建插件然后图像用 BLOB 保存到数据库中
当我将图像获取到数据库时,它无法正常工作。
我的代码 user-management.php
<table cellpadding="5" cellspacing="0">
<thead>
<tr>
<th>Username</th>
<th>Email</th>
<th>First Name</th>
<th>Middle Name</th>
<th>Last Name</th>
<th>Status</th>
<th>Photo</th>
<th>Date</th>
<th>Option</th>
</tr>
</thead>
<tbody>
<?php
global $wpdb;
$myadmin = $wpdb->get_results( "SELECT * FROM jon_admin" );
$color1 = "#F8F8F8";
$color2 = "#FFFFFF";
$row_count = 0;
foreach ($myadmin as $admin) {
$myadminphoto = $wpdb->get_row( "SELECT * FROM jon_admin_photo WHERE user_login = '".$admin->user_login."' " );
$row_color = ($row_count % 2) ? $color1 : $color2;
?>
<tr>
<td style="background-color:<? echo $row_color; ?>"><?php echo $admin->user_login; ?></td>
<td style="background-color:<? echo $row_color; ?>"><?php echo $admin->email; ?></td>
<td style="background-color:<? echo $row_color; ?>"><?php echo $admin->fname; ?></td>
<td style="background-color:<? echo $row_color; ?>"><?php echo $admin->mname; ?></td>
<td style="background-color:<? echo $row_color; ?>"><?php echo $admin->lname; ?></td>
<td style="background-color:<? echo $row_color; ?>"><?php echo $admin->user_status; ?></td>
<td style="background-color:<? echo $row_color; ?>">
<img src="<?php echo plugins_url( 'photo.php', __FILE__ ); ?>?pid=<?php echo $myadminphoto->apid; ?>&img=adminphoto" /> </td>
<td style="background-color:<? echo $row_color; ?>"><?php echo $admin->date; ?></td>
<td style="background-color:<? echo $row_color; ?>">edit view delete</td>
</tr>
<?php
$row_count++;
}
?>
</tbody>
</table>
如果您看到这一行<img src="<?php echo plugins_url( 'photo.php', __FILE__ ); ?>?pid=<?php echo $myadminphoto->apid; ?>&img=adminphoto" />
,我会通过另一个页面 photo.php 调用图像
那么 photo.php 的文件就是这个
if ( $_GET['img'] == 'adminphoto' ) {
global $wpdb;
## VIEW ADMIN PHOTO
$id = $_GET['pid'];
$get_photo = $wpdb->get_row( "SELECT * FROM jon_admin_photo WHERE apid = '".$id."'" );
$content = $get_photo->image;
$filetype = $get_photo->imgcode;
header('Content-type: $filetype');
echo $content;
}
你去,没有图像显示也没有错误显示。
但是当我做这样的事情时,我得到照片的网址然后右键单击打开到新标签,错误说
Fatal error: Call to a member function get_row() on a non-object in C:\xampp\htdocs\web\advanced-nanny\wp-content\plugins\jon-user-management\photo.php on line 37
我的代码有问题吗?
请告诉我谢谢...
