我已经使用这个脚本在我的网站上上传图片一年了,我终于意识到必须进行更改。我一直在互联网上寻找,但还没有找到任何合适的解决方案,所以我来找你。
- 此脚本当前正在创建缩略图并将其移动到属性为 111x111 的文件夹"/images"中。
-
我希望它也上传原始图片,我该怎么做?
if(isset($_POST['submit'])) { if (($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg" || $_FILES["image"]["type"] == "image/gif" || $_FILES["image"]["type"] == "image/x-png") && ($_FILES["image"]["size"] < 4000000)) $current_img=$_FILES['image']['name']; $extension = substr(strrchr($current_img, '.'), 1); date_default_timezone_set("Europe/Stockholm"); $time = date("fYhis"); $new_image = uniqid() . $time; $destination = "images/".$new_image . "-thumb" . "." . $extension; $action = move_uploaded_file($_FILES['image']['tmp_name'], $destination); $max_upload_width = 111; $max_upload_height = 111; if($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg"){ $image_source = imagecreatefromjpeg($destination) ; } if($_FILES["image"]["type"] == "image/gif"){ $image_source = imagecreatefromgif($_FILES["image"]["tmp_name"]); } if($_FILES["image"]["type"] == "image/bmp"){ $image_source = imagecreatefromwbmp($_FILES["image"]["tmp_name"]); } if($_FILES["image"]["type"] == "image/x-png"){ $image_source = imagecreatefrompng($_FILES["image"]["tmp_name"]); } imagejpeg($image_source,$destination,100); chmod($destination,0644); list($image_width, $image_height) = getimagesize($destination); if($image_width>$max_upload_width || $image_height >$max_upload_height){ $proportions = 1; if($image_width>$image_height){ $new_width = $max_upload_width; $new_height = round($max_upload_width/$proportions); } else{ $new_height = $max_upload_height; $new_width = round($max_upload_height*$proportions); } $new_image = imagecreatetruecolor($new_width , $new_height); $image_source = imagecreatefromjpeg($destination); imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height); imagejpeg($new_image, $destination, 100); // save imagedestroy($new_image); }
只需使用以下代码将文件上传到其他目录
$originalImage = "images/".$new_image . "-ImageName" . "." . $extension;
$action = move_uploaded_file($_FILES['image']['tmp_name'], $originalImage)
;
在创建缩略图时,请使用$originalImage而不是 $_FILES['image']['tmp_name']。
通过应用以下代码进行检查
if(isset($_POST['submit'])) {
if (($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg" || $_FILES["image"]["type"] == "image/gif" || $_FILES["image"]["type"] == "image/x-png") && ($_FILES["image"]["size"] < 4000000))
$current_img=$_FILES['image']['name'];
$extension = substr(strrchr($current_img, '.'), 1);
date_default_timezone_set("Europe/Stockholm");
$time = date("fYhis");
$new_image = uniqid() . $time;
$originalImage = "images/".$new_image . "-ImageName" . "." . $extension;
$destination = "images/".$new_image . "-thumb" . "." . $extension;
$action = move_uploaded_file($_FILES['image']['tmp_name'], $originalImage);
$max_upload_width = 111;
$max_upload_height = 111;
if($_FILES["image"]["type"] == "image/jpeg" || $_FILES["image"]["type"] == "image/pjpeg"){
$image_source = imagecreatefromjpeg($originalImage) ;
}
if($_FILES["image"]["type"] == "image/gif"){
$image_source = imagecreatefromgif($originalImage);
}
if($_FILES["image"]["type"] == "image/bmp"){
$image_source = imagecreatefromwbmp($originalImage);
}
if($_FILES["image"]["type"] == "image/x-png"){
$image_source = imagecreatefrompng($originalImage);
}
imagejpeg($image_source,$destination,100);
chmod($destination,0644);
list($image_width, $image_height) = getimagesize($destination);
if($image_width>$max_upload_width || $image_height >$max_upload_height){
$proportions = 1;
if($image_width>$image_height){
$new_width = $max_upload_width;
$new_height = round($max_upload_width/$proportions);
}
else{
$new_height = $max_upload_height;
$new_width = round($max_upload_height*$proportions);
}
$new_image = imagecreatetruecolor($new_width , $new_height);
$image_source = imagecreatefromjpeg($destination);
imagecopyresampled($new_image, $image_source, 0, 0, 0, 0, $new_width, $new_height, $image_width, $image_height);
imagejpeg($new_image, $destination, 100); // save
imagedestroy($new_image);
