在下面的代码中,它正在上传所有文件类型,但我只需要doc和pdf文件
我尝试使用以下代码进行上传文件限制但不起作用
我想只上传doc和pdf文件帮助我的朋友们我可能知道该怎么做
<?php
if(isset($_POST['name']))
{
$name=$email=$phone=$uploadresume="";
$nameErr=$emailErr=$phoneErr=$uploadresumeErr="";

关于同一主题已经存在一些问题。我会再次发布答案,我猜......
$finfo = finfo_open(FILEINFO_MIME_TYPE);
$mime = finfo_file($finfo, $_FILES['file']['TMP_NAME']);
switch ($mime) {
case 'image/jpeg':
case 'application/pdf':
case etc....:
default:
die("Unknown/not permitted file type");
}

注意:这个简单的解决方案主要在使用codeigniter框架时起作用
$config['upload_path'] = './uploads/;
$config['allowed_types'] = 'pdf,doc,docx';
$config['max_size'] = 0;
$config['max_width'] = 0;
$config['max_height'] = 0;
$config['file_name'] = round(100,99); //make your file name random
$this->load->library('upload', $config);
$this->upload->initialize($config);
if($this->upload->do_upload('file_name')){
print $this->upload->data();
}else{
print $this->upload->display_errors();
}
