我嘗試使用PHP上傳的服務器多張照片,下面是我用來上傳代碼:問題PHP多圖片上傳
private function handle_file_upload($uploaded_file, $name, $size, $type, $error) {
$file = new stdClass();
// Remove path information and dots around the filename, to prevent uploading
// into different directories or replacing hidden system files.
// Also remove control characters and spaces (\x00..\x20) around the filename:
$file->name = trim(basename(stripslashes($name)), ".\x00..\x20");
$file->size = intval($size);
$file->type = $type;
$error = $this->has_error($uploaded_file, $file, $error);
if (!$error && $file->name) {
$file_path = $this->options['upload_dir'].$file->name;
$append_file = is_file($file_path) && $file->size > filesize($file_path);
clearstatcache();
if ($uploaded_file && is_uploaded_file($uploaded_file)) {
// multipart/formdata uploads (POST method uploads)
if ($append_file) {
file_put_contents(
$file_path,
fopen($uploaded_file, 'r'),
FILE_APPEND
);
} else {
move_uploaded_file($uploaded_file, $file_path);
}
} else {
// Non-multipart uploads (PUT method support)
file_put_contents(
$file_path,
fopen('php://input', 'r'),
$append_file ? FILE_APPEND : 0
);
}
$file_size = filesize($file_path);
if ($file_size === $file->size) {
$file->url = $this->options['upload_url'].rawurlencode($file->name);
foreach($this->options['image_versions'] as $version => $options) {
if ($this->create_scaled_image($file->name, $options)) {
$file->{$version.'_url'} = $options['upload_url']
.rawurlencode($file->name);
}
}
} else if ($this->options['discard_aborted_uploads']) {
unlink($file_path);
$file->error = 'abort';
}
$file->size = $file_size;
$file->delete_url = $this->options['script_url']
.'?file='.rawurlencode($file->name);
$file->delete_type = 'DELETE';
} else {
$file->error = $error;
}
return $file;
}
public function post() {
$upload = isset($_FILES[$this->options['param_name']]) ?
$_FILES[$this->options['param_name']] : array(
'tmp_name' => null,
'name' => null,
'size' => null,
'type' => null,
'error' => null
);
$info = array();
if (is_array($upload['tmp_name'])) {
foreach ($upload['tmp_name'] as $index => $value) {
$info[] = $this->handle_file_upload(
$upload['tmp_name'][$index],
isset($_SERVER['HTTP_X_FILE_NAME']) ?
$_SERVER['HTTP_X_FILE_NAME'] : $upload['name'][$index],
isset($_SERVER['HTTP_X_FILE_SIZE']) ?
$_SERVER['HTTP_X_FILE_SIZE'] : $upload['size'][$index],
isset($_SERVER['HTTP_X_FILE_TYPE']) ?
$_SERVER['HTTP_X_FILE_TYPE'] : $upload['type'][$index],
$upload['error'][$index]
);
}
} else {
$info[] = $this->handle_file_upload(
$upload['tmp_name'],
isset($_SERVER['HTTP_X_FILE_NAME']) ?
$_SERVER['HTTP_X_FILE_NAME'] : $upload['name'],
isset($_SERVER['HTTP_X_FILE_SIZE']) ?
$_SERVER['HTTP_X_FILE_SIZE'] : $upload['size'],
isset($_SERVER['HTTP_X_FILE_TYPE']) ?
$_SERVER['HTTP_X_FILE_TYPE'] : $upload['type'],
$upload['error']
);
}
header('Vary: Accept');
if (isset($_SERVER['HTTP_ACCEPT']) &&
(strpos($_SERVER['HTTP_ACCEPT'], 'application/json') !== false)) {
header('Content-type: application/json');
} else {
header('Content-type: text/plain');
}
echo json_encode($info);
}
目前的代碼工作正常上傳圖片,但圖片存儲原始圖像名稱到服務器,如果我再次上傳相同的圖像,它不會允許我將重複的圖像存儲在服務器中,並且一些圖像是不同的類型,如png或gif,我想要做的是我想要爲所有上傳的圖像分配一個唯一的ID並將所有圖像保存到服務器中的jpg文件中,我該如何實現這一目標,如果您可以根據我的代碼進行說明,那將非常好,謝謝!
爲什麼你要轉換爲JPEG:這個功能
