剛剛通過將中的resize()
方法複製到我的控制器並將其修改爲調整system/upload
文件夾中的圖像大小來解決問題。
private function resizeImageUpload($old_filename, $width, $height, $new_filename = '') {
$extension_arr = array('jpeg', 'jpg', 'png', 'gif');
$old_image = $old_filename;
if (!empty($new_filename)) {
$extension = pathinfo($new_filename, PATHINFO_EXTENSION);
$new_image = 'cache/system/upload/' . utf8_substr($new_filename, 0, utf8_strrpos($new_filename, '.')) . '-' . $width . 'x' . $height . '.' . $extension;
} else {
$extension = pathinfo($old_filename, PATHINFO_EXTENSION);
$new_image = 'cache/system/upload/' . utf8_substr($old_filename, 0, utf8_strrpos($old_filename, '.')) . '-' . $width . 'x' . $height . '.' . $extension;
}
if (!in_array($extension, $extension_arr)) return '';
if (!is_file(DIR_IMAGE . $new_image) || (filectime(DIR_UPLOAD . $old_image) > filectime(DIR_IMAGE . $new_image))) {
$path = '';
$directories = explode('/', dirname(str_replace('../', '', $new_image)));
foreach ($directories as $directory) {
$path = $path . '/' . $directory;
if (!is_dir(DIR_IMAGE . $path)) {
@mkdir(DIR_IMAGE . $path, 0777);
}
}
list($width_orig, $height_orig) = getimagesize(DIR_UPLOAD . $old_image);
if ($width_orig != $width || $height_orig != $height) {
$image = new Image(DIR_UPLOAD . $old_image);
$image->resize($width, $height);
$image->save(DIR_IMAGE . $new_image);
} else {
$success = copy(DIR_UPLOAD . $old_image, DIR_IMAGE . $new_image);
}
}
if ($this->request->server['HTTPS']) {
return HTTPS_CATALOG . 'image/' . $new_image;
} else {
return HTTP_CATALOG . 'image/' . $new_image;
}
}
我不明白你爲什麼要調整文件本身的大小。你可以在標籤上使用CSS屬性的寬度和高度,不是嗎? –
調整大小以生成圖像的縮略圖。 – Eaton
