我真的搜索了所有网站并尝试使用 GD getimagesize 函数,但没有希望,我想在上传时设置最小和最大图像宽度和高度..所以如果不相等则显示错误;这是原始代码:
<?php
$page = "user_editprofile_photo";
include "header.php";
$task = ( isset($_POST['task']) ? $_POST['task'] : NULL );
// CHECK FOR ADMIN ALLOWANCE OF PHOTO
if( !$user->level_info['level_photo_allow'] )
{
header("Location: user_home.php");
exit();
}
// SET ERROR VARIABLES
$is_error = 0;
// DELETE PHOTO
if( $task == "remove" )
{
$user->user_photo_delete();
$user->user_lastupdate();
exit();
}
// UPLOAD PHOTO
if( $task == "upload" )
{
$user->user_photo_upload("photo");
$is_error = $user->is_error;
if( !$is_error )
{
// SAVE LAST UPDATE DATE
$user->user_lastupdate();
// DETERMINE SIZE OF THUMBNAIL TO SHOW IN ACTION
$photo_width = $misc->photo_size($user->user_photo(), "100", "100", "w");
$photo_height = $misc->photo_size($user->user_photo(), "100", "100", "h");
// INSERT ACTION
$action_media = Array(Array('media_link'=>$url->url_create('profile', $user->user_info['user_username']), 'media_path'=>$user->user_photo(), 'media_width'=>$photo_width, 'media_height'=>$photo_height));
$actions->actions_add($user, "editphoto", Array($user->user_info['user_username'], $user->user_displayname), $action_media, 999999999, TRUE, "user", $user->user_info['user_id'], $user->user_info['user_privacy']);
}
}
// GET TABS TO DISPLAY ON TOP MENU
$field = new se_field("profile", $user->profile_info);
$field->cat_list(0, 0, 0, "profilecat_id='{$user->user_info['user_profilecat_id']}'");
$cat_array = $field->subcats;
// ASSIGN VARIABLES AND INCLUDE FOOTER
$smarty->assign('is_error', $is_error);
$smarty->assign('cats', $cat_array);
include "footer.php";
?>
我在这里补充:
if( $task == "upload" )
$photo=$user->user_photo();
{
list($img_width, $img_height, $img_type, $attrs)=getimagesize($photo);
if($img_width >= 193 && $img_height >= 290)
$user->user_photo_upload("photo");
$is_error = $user->is_error;
if( !$is_error )
1-以这种方式:
if($task == "upload")$photo = $user->user_photo();
{ $user->user_photo_upload("photo");
根本不会上传任何图像......
2-以这种方式:
if($task == "upload"){
$user->user_photo_upload("photo");
$photo = $user->user_photo();
没有效果..它甚至上传 16px 的图像。谢谢,如果你能帮忙,我将不胜感激。
