警告:getimagesize(image.jpg) [ ]: 无法打开流:没有这样的文件或目录

Warning: getimagesize(image.jpg) [ ]: failed to open stream: no such file or directory

我在裁剪图像时遇到问题,但是当我在更改为裁剪的某些代码之前用于调整图像大小时,此源工作正常。

这是裁剪的来源:

$filenames1 = stripslashes($_FILES['txtfile1']['name']);
$exts1 = substr($images1, strrpos($images1, '.')+1);
$idimgs = md5(uniqid() . time() . $filenames1) . "-1." . $exts1;
$target_files1 = $target_dir . basename($idimgs);

    list($width, $height) = getimagesize($filenames1);

    $realImages             = imagecreatefromjpeg($_FILES['txtfile1']['tmp_name']);

    if ($width > $height) {
    $y = 0;
    $x = ($width - $height) / 2;
    $smallestSide = $height;
    } else {
    $x = 0;
    $y = ($height - $width) / 2;
    $smallestSide = $width;
    }

    $thumbSize     = 200;

    $thumbImage = imagecreatetruecolor($thumbSize, $thumbSize);
    imagecopyresampled($thumbImage, $realImages, 0,0,$x,$y, $thumbSize, $thumbSize, $smallestSide, $smallestSide);

    imagejpeg($thumbImage,$target_dir.$idimgs);

    imagedestroy($realImages);
    imagedestroy($thumbImage);

如何解决这个问题?

php 无法直接从客户端系统访问文件。您在这里尝试访问 $_FILES['txtfile1']['name'] 而不是尝试 getimagesize($_FILES['txtfile1']['tmp_name'])
