【问题描述】:
我正在尝试将图片上传到网站。我还尝试在写入目录之前调整图像大小。图片上传正常,但无论出于何种原因 move_uploaded_file 函数返回 false,即使文件实际上正在上传。请在下面查看我的一些代码:
$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.";
}
屏幕没有被重定向到 Picture.php,而是返回“抱歉,上传您的文件时出现问题”。但是,当我在网站上查看图片时,我可以看到图像成功存在。我检查了错误日志,也没有任何显示,所以我很茫然。任何建议或想法表示赞赏!

如果您使用 imagick,请先尝试移动上传的文件或 file_put_contents,然后调整图像大小,创建缩略图或修改文件,并保存您修改后的副本 mh?
