The code is as follows Copy Code

CREATE TABLE ' seminar_upload_img ' (
' id ' int (one) not NULL auto_increment,
' Img_name ' varchar (255) DEFAULT NULL COMMENT ' picture name ',
' Img_url ' varchar (255) DEFAULT NULL COMMENT ' picture path ',
' Create_time ' text,
PRIMARY KEY (' id ')
) Engine=innodb auto_increment=23 DEFAULT Charset=utf8;

Connect the database in the public profile common/conf.php and configure the address

  code is as follows copy code
Return Array (
' Db_type ' => ' MySQL ',
' Db_host ' => ' 127.0.0.1 ',
' Db_name ' => ' seminar ',
' Db_user ' => ' root ',
' Db_pwd ' => ' root ',
' Db_port ' =>3306,
' Db_prefix ' => ' seminar_ ',
' Db_charset ' => ' UTF8 ',

' Show_page_trace ' =>true,

/* Address Replacement * *
' Tmpl_parse_string ' =>array (
' __upload__ ' =>__root__. ' /public/uploads ',
),
);

Implement upload file in controller UploadController.class.php

The code is as follows Copy Code
namespace Home\controller;
Use Think\controller;
Class Uploadcontroller extends Controller {
Public Function index () {
$img =m (' upload_img ');
$sel = $img->order (' create_time desc ')->find ();
$this->assign (' data ', $sel);
$this->display ();
}
Public function upload () {
$upload _img=m (' upload_img ');
if (!empty ($_files)) {
Upload a single image
$upload = new \think\upload ()///materialized upload class
$upload->maxsize = 1*1024*1024//Set attachment upload size
$upload->exts = array (' jpg ', ' gif ', ' PNG ', ' jpeg ');//Set attachment upload type
$upload->rootpath = ' public/uploads/'; Set attachment upload root directory
$upload->savepath = '; Set attachment upload (sub) directory
$upload->savename=array (' uniqid ', ');//upload file Save rule
$upload->autosub = true;//automatically use subdirectories to save uploaded files
$upload->subname = Array (' Date ', ' Ymd ');
Upload a single picture
$info = $upload->uploadone ($_files[' image '));
if (! $info) {//Upload error message
$this->error ($upload->geterror ());
}else{//upload successfully upload file information
$img _url= $info [' Savepath ']. $info [' Savename '];
$data [' Img_url ']= $img _url;
$data [' Img_name ']= $info [' Savename '];
$data [' Create_time ']=now_time;
$upload _img->create ($data);
$result = $upload _img->add ();
if (! $result) {
$this->error (' Upload failed! ');
}else{
$this->success (' upload success ');
}
}
}
}
}

thinkphp to achieve multiple file upload

The code is as follows Copy Code

<?php

Class Uploadaction extends Action {
function upload () {
$file =m (' upload_img ');
$list = $file->select ();
$this->assign (' list ', $list);
$this->display ();
}
function uploads () {
File upload address submitted to him, and upload completed after the return of a message to write to the database
If $_files is empty, I'll let the action give us an error indicating that the user must choose to upload the file, then call the Up method
if (empty ($_files)) {
$this->error (' must choose to upload file ');
}
else{
$result = $this->up ();
if (Isset ($result)) {
Ways to write to a database
if ($this->c ($result)) {
$this->success (' Upload success! ');
}else{$this->error (' Write database failed! ');}

}else{$this->error (' upload file has an exception, please contact the system Administrator ');}
}
}
The core method of uploading files
Private function up () {
Private method, in this method, completes the call of the file upload class related to the thinkphp
Import (' @.org.uploadfile ');
$upload =new UploadFile ();
$upload->maxsize= ' 10000000 '//refers to the size of the uploaded file, the default is-1 is an infinite size
$upload->savepath= './public/upload/'; Where to save files after uploading? It is best to use the statistical catalogue
$upload->saverule= ' uniqid '; File name save rule for uploading files
$upload->autocheck=true; Whether attachments are automatically detected
$upload->uploadreplace=true;//If a file with the same name is overwritten
$upload->allowexts=array (' jpg ', ' jpeg ', ' gif ', ' PNG ');//allow the extension of the surviving file
$upload->allowtypes=array (' image/png ', ' image/jpg ', ' image/png ', ' image/jpeg '); Detecting MIME Types
$upload->thumb=true;//whether to open picture file abbreviations
$upload->thumbmaxwidth= ' 200,300 '; A string format to pass, if you want to have more than one, that is used here, split write multiple parameters
$upload->thumbmaxheight= ' 400,500 ';
$upload->thumbprefix= ' s_,m_ '; Thumbnail file prefix
$upload->thumbsuffix= '-s,-m ';/suffix
$file->thumbremoveorigin=true;
There is also a file name in the database
$upload->thumbremoveorigin=1;//If a thumbnail is generated, delete the original image
Upload () failed to return true if upload succeeded false
if ($upload->upload ()) {
$info = $upload->getuploadfileinfo ()//local variable, save upload success Information
return $info;
}else{
$this->error ($upload->geterrormsg ());
}

}
Private Function C ($data) {
$file =m (' upload_img ');
if ($data) {
for ($i =0; $i <count ($data); $i + +) {
$img [' img ']= $data [$i] [' savename ']; Equivalent to $img=array (' img ' => $data [0][' Savename ']);
$file->add ($IMG);
}
return true;
