thinkphp3.1 上传图片和文档,怎么分开保存?
回复讨论(解决方案)
根据文件后缀,判断上传目录选择
根据文件后缀,判断上传目录选择
$upload->savePath= './Public/image/home/news/';
if(!$upload->upload()) {// 上传错误提示错误信息
$this->error($upload->getErrorMsg());
}else{// 上传成功 获取上传文件信息
$info = $upload->getUploadFileInfo();
}
这个上传目录不是只能设置一个么,怎么设置两个,thinkphp上传类第一次用。
thinkphp3.1 没有提供相应的方案,所以需要你自己设计
你可以继承 UploadFile 类,重写 save 方法
也可以用自己的上传类完成
如果你可以获取文件后缀$type
if ($type == '.jpg'){
$upload->savePath= './Public/image/home/ new1/';
if(!$upload->upload()) {// 上传错误提示错误信息
$this->error($upload->getErrorMsg());
}else{// 上传成功 获取上传文件信息
$info = $upload->getUploadFileInfo();
}
}else if ($type == '.txt'){
$upload->savePath= './Public/image/home /new2/';
if(!$upload->upload()) {// 上传错误提示错误信息
$this->error($upload->getErrorMsg());
}else{// 上传成功 获取上传文件信息
$info = $upload->getUploadFileInfo();
}
}
如果我上传的是一个图片一个文档 2 个个文件呢?
如果你可以获取文件后缀$type
if ($type == '.jpg'){
$upload->savePath= './Public/image/home/ new1/';
if(!$upload->upload()) {// 上传错误提示错误信息
$this->error($upload->getErrorMsg());
}else{// 上传成功 获取上传文件信息
$info = $upload->getUploadFileInfo();
}
}else if ($type == '.txt'){
$upload->savePath= './Public/image/home /new2/';
if(!$upload->upload()) {// 上传错误提示错误信息
$this->error($upload->getErrorMsg());
}else{// 上传成功 获取上传文件信息
$info = $upload->getUploadFileInfo();
}
}
如果同时上传多个文件,应该会有多个file文件域吧?
这就对file判断不就是?
如果你愿意修改 UploadFile.class.php 文件的话,事情还是有转机的
把 getSaveName 方法中的(408行附近)
$saveName = $rule().".".$filename['extension'];
改成
$saveName = $rule($filename).".".$filename['extension'];
然后
$upload->savePath = '';$upload->saveRule = 'myFunction';
定义函数
function myFunction($filename) { $p = in_array($filename['extension'], array('gif', 'jpg', 'png')) ? '图片路径' : '文档路径'; return $p . $filename['name'];}
由于之后还会加上后缀,所以 $filename['name'] 怎么变形你可随意

import('ORG.Net.UploadFile');
$upload = new UploadFile();// 实例化上传类
$upload->maxSize = 3145728;
$upload->savePath = '';
$upload->saveRule = 'myFunction';
if(!$upload->upload()) {// 上传错误提示错误信息
$this->error($upload->getErrorMsg());
}else{// 上传成功 获取上传文件信息
$info = $upload->getUploadFileInfo();
}
private function getSaveName($filename) {
$rule = $this->saveRule;
if(empty($rule)) {//没有定义命名规则,则保持文件名不变
$saveName = $filename['name'];
}else {
if(function_exists($rule)) {
//使用函数生成一个唯一文件标识号
$saveName = $rule($filename).".".$filename['extension'];
}else {
//使用给定的文件名作为标识号
$saveName = $rule.".".$filename['extension'];
}
}
if($this->autoSub) {
// 使用子目录保存文件
$filename['savename'] = $saveName;
$saveName = $this->getSubName($filename).$saveName;
}
return $saveName;
}
function my_filename() {
return date('ymdHis',time()).'_'.mt_rand();
}
function myFunction($filename) {
$p = in_array($filename['extension'], array('gif', 'jpg', 'png')) ? './Public/image/home/img/' : './Public/image/home/file/';
return $p . $filename[my_filename()];
}
改了,这三个地方,提示上传路径不存在。
是空的,我在上传目录不存在上一句输出了下。
既然你的 ./Public/image/home/ 是公共的,那么就
$upload->savePath = './Public/image/home/';
函数里只留 'img/' : 'file/'

版主大大,路径可以用了,不过现在是名字是空的了。
文件已经存在!./Public/image/home/img/.jpg
return $p . $filename[my_filename()];
应为
return $p . my_filename();
可直接写作
return $p . date('ymdHis_').mt_rand();
return $p . $filename[my_filename()];
应为
return $p . my_filename();
可直接写作
return $p . date('ymdHis_').mt_rand();恩恩,谢谢版主大大了,第一次用框架,几个问题都是版主大大解决的。

PHP remains a powerful and widely used tool in modern programming, especially in the field of web development. 1) PHP is easy to use and seamlessly integrated with databases, and is the first choice for many developers. 2) It supports dynamic content generation and object-oriented programming, suitable for quickly creating and maintaining websites. 3) PHP's performance can be improved by caching and optimizing database queries, and its extensive community and rich ecosystem make it still important in today's technology stack.

In PHP, weak references are implemented through the WeakReference class and will not prevent the garbage collector from reclaiming objects. Weak references are suitable for scenarios such as caching systems and event listeners. It should be noted that it cannot guarantee the survival of objects and that garbage collection may be delayed.

The \_\_invoke method allows objects to be called like functions. 1. Define the \_\_invoke method so that the object can be called. 2. When using the $obj(...) syntax, PHP will execute the \_\_invoke method. 3. Suitable for scenarios such as logging and calculator, improving code flexibility and readability.

Fibers was introduced in PHP8.1, improving concurrent processing capabilities. 1) Fibers is a lightweight concurrency model similar to coroutines. 2) They allow developers to manually control the execution flow of tasks and are suitable for handling I/O-intensive tasks. 3) Using Fibers can write more efficient and responsive code.

The PHP community provides rich resources and support to help developers grow. 1) Resources include official documentation, tutorials, blogs and open source projects such as Laravel and Symfony. 2) Support can be obtained through StackOverflow, Reddit and Slack channels. 3) Development trends can be learned by following RFC. 4) Integration into the community can be achieved through active participation, contribution to code and learning sharing.

PHP and Python each have their own advantages, and the choice should be based on project requirements. 1.PHP is suitable for web development, with simple syntax and high execution efficiency. 2. Python is suitable for data science and machine learning, with concise syntax and rich libraries.

PHP is not dying, but constantly adapting and evolving. 1) PHP has undergone multiple version iterations since 1994 to adapt to new technology trends. 2) It is currently widely used in e-commerce, content management systems and other fields. 3) PHP8 introduces JIT compiler and other functions to improve performance and modernization. 4) Use OPcache and follow PSR-12 standards to optimize performance and code quality.

The future of PHP will be achieved by adapting to new technology trends and introducing innovative features: 1) Adapting to cloud computing, containerization and microservice architectures, supporting Docker and Kubernetes; 2) introducing JIT compilers and enumeration types to improve performance and data processing efficiency; 3) Continuously optimize performance and promote best practices.
