错误发生在第27行" getimagesize"功能,我上传图像在相同的"路径" ,但是当我继续操作时,我每次都会收到此错误,以及图像正常的文件夹的路径
PHP //连接到数据库
$link = mysql_connect("localhost" , "333" , "3333")
or die( "could not connect " . mysql_error() );
mysql_select_db("moviesite" , $link)
or die ( mysql_error() );
// make variables available
$id = $_REQUEST['id'];
if (isset($_REQUEST['mode']))
{
$move = $_REQUEST['mode'];
}
else
{
$mode = '' ;
}
// get info on the pic we want
$getpic = mysql_query("SELECT * FROM images WHERE image_id = '$id' ")
or die( mysql_error() ) ;
$rows = mysql_fetch_array($getpic);
extract($rows);
$image_filename = "upload/" . $image_id . ".jpg" ;
list($width, $height, $type, $attr) = getimagesize($image_filename);
答案 0 :(得分:0)
首先尝试检查文件是否存在:
if (!file_exists($image_filename)){
echo "file not found!";
exit;
}
