我有一个简单的多图像上传脚本,可以调整图像的大小以保持纵横比。调整大小工作正常。然而,我似乎无法将图像发送到正确的文件夹,即使语法正确。在上传时发送调整大小的图像的路径php
以下是我简而言之正在做:
如果文件输入“图像”不为空,然后创建“../company_images”内的新文件夹创建的文件夹的名称是uniqid由“$ photo_directory_name”变量定义。在为每个图像运行调整大小功能后,将调整大小的图像放入由“$ total_path”变量定义的上传文件夹中。
if(!empty($_FILES["Image"])){
$photo_directory_name = uniqid(rand(100, 1000));
$photos_path = "company_images/" . $photo_directory_name;
$directory = "../company_images/";
if (!file_exists($directory . $photo_directory_name)) {
$upload_dir = mkdir($directory . $photo_directory_name, 0777, TRUE);
}else{
$upload_dir = $directory . $photo_directory_name;
}
function resize($width, $height){
/* Get original image x y*/
list($w, $h) = getimagesize($_FILES['Image']['tmp_name']);
/* calculate new image size with ratio */
$ratio = max($width/$w, $height/$h);
$h = ceil($height/$ratio);
$x = ($w - $width/$ratio)/2;
$w = ceil($width/$ratio);
/* new file name */
$path = $width.'x'.$height.'_'.$_FILES['Image']['name'];
$total_path = $directory . $photo_directory_name . $path;
/* read binary data from image file */
$imgString = file_get_contents($_FILES['Image']['tmp_name']);
/* create image from string */
$image = imagecreatefromstring($imgString);
$tmp = imagecreatetruecolor($width, $height);
imagecopyresampled($tmp, $image,
0, 0,
$x, 0,
$width, $height,
$w, $h);
/* Save image */
switch ($_FILES['Image']['type']) {
case 'image/jpeg':
imagejpeg($tmp, $total_path, 100);
break;
case 'image/png':
imagepng($tmp, $total_path, 0);
break;
case 'image/gif':
imagegif($tmp, $total_path);
break;
default:
exit;
break;
}
return $total_path;
/* cleanup memory */
imagedestroy($image);
imagedestroy($tmp);
}
$max_file_size = 1024*1000; // 1mb
$valid_exts = array('jpeg', 'jpg', 'png', 'gif');
// thumbnail sizes
$sizes = array(1200 => 1000);
if ($_SERVER['REQUEST_METHOD'] == 'POST' AND isset($_FILES['Image'])) {
if($_FILES['Image']['size'] < $max_file_size){
// get file extension
$ext = strtolower(pathinfo($_FILES['Image']['name'], PATHINFO_EXTENSION));
if (in_array($ext, $valid_exts)) {
/* resize image */
foreach ($sizes as $w => $h) {
$files[] = resize($w, $h);
}
} else {
$response["message"] = 'photos_invalid_format';
$errors++;
}
} else{
$response["message"] = 'photos_file_too_large';
$errors++;
}
}
echo $total_path;
}
任何帮助,非常感谢。由于
所以调整大小的图像存储在错误的文件夹?哪个文件夹? – James
如果没有保存,它可能是一个权限/访问被拒绝的错误。在许多系统上,PHP现在以“nobody”身份运行,而不是apache/ftp/WWW用户。 –
@詹姆斯是的,这是正确的。它将它们存储在company_images中,而不是company_images/$ photo_directory_name – bob
