我想用PHP重新调整大小,重命名和上传图像。
所以我的工作脚本如下:
posPercents.Length - 1
此脚本出现问题是上传两张图片:
为什么?
答案 0 :(得分:0)
您正在创建图像,然后移动上传的文件,这就是它创建两个文件的原因。我相信你的代码应该是:
$file_name = $_FILES['HOT_Logo']['name'];
$file_tmp_name = $_FILES['HOT_Logo']['tmp_name'];
$file_target = '../../images/hotel-logos/';
$file_size = $_FILES['HOT_Logo']['size'];
// Resize
$ratio = $width/$height;
if($ratio > 1) {
$new_width = 300;
$new_height = 300/$ratio;
}
else {
$new_width = 300*$ratio;
$new_height = 300;
}
// Rename file
$temp = explode('.', $file_name);
$newfilename = 'new_img_name.'.end($temp);
// Upload image
if(move_uploaded_file($file_tmp_name , $file_target.$newfilename)) {
$src = imagecreatefromstring(file_get_contents($file_target.$newfilename));
$dst = imagecreatetruecolor($new_width, $new_height);
imagecopyresampled($dst, $src, 0, 0, 0, 0, $new_width, $new_height, $width, $height);
imagedestroy($src);
imagepng($dst, $file_target.$newfilename);
imagedestroy($dst);
....
}
