我正在尝试为网站创建图片上传。我也试图在写入目录之前调整图像大小。图片正在上传很好,但无论出于何种原因,move_uploaded_file函数返回false,即使文件实际上传了。请参阅下面的一些代码:

$fileType = $_FILES['photo_one']['type'];

 //This gets all the other information from the form 
 $pic=($_FILES['photo_one']['name']); 
$tmppic = ($_FILES['photo_one']['tmp_name']);
$front=uniqid (rand (),false);
$newpic=$front.'_'.$pic;
$newtmppic=$front.'_'.$tmppic;



if($fileType == 'image/jpg' || $fileType == 'image/jpeg' )
{
$tmppic = ($_FILES['photo_one']['tmp_name']);
$src = imagecreatefromjpeg($tmppic);
}
else if($fileType == 'image/png')
{
$tmppic = ($_FILES['photo_one']['tmp_name']);
$src = imagecreatefrompng($tmppic);
}
else 
{
$src = imagecreatefromgif($tmppic);
}


list($width,$height)=getimagesize($tmppic);

$newwidth='700px';
$newheight=($height/$width)*$newwidth;
$tmp=imagecreatetruecolor($newwidth,$newheight);

imagecopyresampled($tmp,$src,0,0,0,0,$newwidth,$newheight,$width,$height);

 //This is the directory where images will be saved 
 $target = "../secure/profile_images/"; 
 $newtarget = $target . basename($newpic); 

imagejpeg($tmp,$newtarget,100);

 //Writes the photo to the server 
 if(move_uploaded_file($tmp, $newtarget)) 
 { 

 //Tells you if its all ok 
header('Location: Picture.php#A1');
 } 
 else { 
  //Gives an error if its not 
 echo "Sorry, there was a problem uploading your file."; 
 } 

屏幕返回“抱歉,上传文件时出现问题”,而不是重定向到Picture.php。但是,当我在网站上查看图片时,我可以看到图像在那里成功。我检查了错误日志,没有显示在那里,所以我不知所措。任何建议或想法都表示赞赏!

问题是您使用imagejpeg($tmp,$newtarget)创建图像,该图像创建图像并将其存储在指定的路径中,并尝试移动已创建并存储在服务器上的同一文件。 imagejpeg将创建映像并将其存储在服务器上,而不使用move_uploaded_file函数。如果要检查文件是否已创建,请使用以下代码删除move_uploaded_file函数。

//Writes the photo to the server 
if(imagejpeg($tmp,$newtarget,100)) 
{ 

 //Tells you if its all ok 
 header('Location: Picture.php#A1');
} 
  else { 
 //Gives an error if its not 
  echo "Sorry, there was a problem uploading your file."; 
 }
