所以我使用的是别人制作的脚本。Wordpress网站。
我想更改默认上传位置:
mysite.com/wp-content/themes/theme_name/images/avatar/avatarnamehere20.jpg
:
mysite.com/images/avatar/avatarnamehere20.jpg
无论如何,这是第一个场景的工作代码:
处理上传代码
if(isset($_FILES['image']))
$avatar = $_FILES['image'];
$save_to = "/images/avatar";
$logo_results = tgt_resize_image($avatar['tmp_name'] ,$save_to,150,150,$avatar['type'], get_the_author_meta('display_name', $user_ID));
if ($logo_results === false)
{
global $errors;
$errors .= __("Error: We can't upload your avatar", 'ad')."<br>";
}
else{
$avatar = get_user_meta($user_ID,'tgt_image',true);
if(file_exists(TEMPLATEPATH . $avatar) && $avatar != '/images/avatar.png')
unlink(TEMPLATEPATH . $avatar);
$avatar = $logo_results;
update_user_meta($user_ID,'tgt_image',$avatar);
}
函数tgt_resize_image
function tgt_resize_image($ipath, $tdir, $twidth, $theight, $image_type, $name_image){
try{
$simg = '';
//check image type
$type_arr = array('image/jpg', 'image/jpeg', 'image/pjpeg');
if (in_array($image_type, $type_arr))
{

我尝试了几次修改代码。我设法让mysql字段正确更新,但文件根本不会上传。因此,页面试图显示图像,但它不存在。
这是我得到的:
if(isset($_FILES['image']))
$avatar = $_FILES['image'];
//$save_to = "/images/avatar";
$save_to = site_url('/') . 'images/avatar';
$logo_results = tgt_resize_image($avatar['tmp_name'] ,$save_to,150,150,$avatar['type'], get_the_author_meta('display_name', $user_ID));
if ($logo_results === false)
{
global $errors;
$errors .= __("Error: We can't upload your avatar", 'ad')."<br>";
}
else{
$avatar = get_user_meta($user_ID,'tgt_image',true);
if(file_exists(site_url('/') . $avatar) && $avatar != '/images/avatar.png')
unlink(site_url('/') . $avatar);
$avatar = $logo_results;
update_user_meta($user_ID,'tgt_image',$avatar);
}
//wp_redirect( get_bloginfo('url').'/?author='.$current_user->ID );
wp_redirect(get_author_posts_url($user_ID));
exit;
在tgt_resize_image函数中,我将TEMPLATEPATH更改为site_url('/'),但这不起作用。
任何帮助都是感激的!我会奖励那些帮助我的人,因为这是令人沮丧的!
如果你需要更多的信息或代码,请告诉我。
再次感谢!
好了,我找到答案了!
函数中:tgt_resize_image
imagejpeg, imagepng和imagegif正在保存图像文件。
TEMPLATEPATH指向WP模板位置。
使用site_url()将无法工作,因为它现在将指向web位置(mysite.com)。
我必须将TEMPLATEPATH替换为$_SERVER['DOCUMENT_ROOT'],它最终工作正常。
祝你好运!
