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。我一直在寻找整个互联网，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具有 111x111 属性的文件夹“/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不同的目录

$originalImage  = "images/".$new_image . "-ImageName" . "." . $extension;

$action = move_uploaded_file($_FILES['image']['tmp_name'], $originalImage)

;

并在创建缩略图时使用 $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);
}
