Codeigniter implements multifile Upload and creates multiple thumbnails _ PHP Tutorial

1. Upload 5 images at the same time
2. generate two types of thumbnails at the same time
3. save to mysql

Controllers: upload. php file:

The code is as follows:

Class Upload extends Controller {
Function go (){
If (isset ($ _ POST ['go']) {
// Initialization
$ Config ['upload _ path'] = 'Album/source ';
$ Config ['allowed _ types'] = 'gif | jpg | png | bmp | jpeg ';
$ Config ['encryption _ name'] = TRUE;
$ Config ['remove _ spaces'] = TRUE;
$ Config ['max _ size'] = '0 ';
$ Config ['max _ width'] = '0 ';
$ Config ['max _ height'] = '0 ';

$ This-> load-> library ('upload', $ config );

// 170*170 images
$ ConfigThumb = array ();
$ ConfigThumb ['image _ library'] = 'gd2 ';
$ ConfigThumb ['Source _ image'] = '';
$ ConfigThumb ['create _ thumb'] = TRUE;
$ ConfigThumb ['maintain _ ratio '] = TRUE; // preserve the image proportion
$ ConfigThumb ['new _ image'] = 'Album/thumb ';
$ ConfigThumb ['width'] = 170;
$ ConfigThumb ["height"] = 170;
// 600*600 images
$ ConfigLarge = array ();
$ ConfigLarge ['image _ library'] = 'gd2 ';
$ ConfigLarge ['Source _ image'] = '';
$ ConfigLarge ['create _ thumb'] = TRUE;
$ ConfigLarge ['maintain _ ratio '] = TRUE; // preserve the image proportion
$ ConfigLarge ['new _ image'] = 'Album/large ';
$ ConfigLarge ['width'] = 600;
$ ConfigLarge ['height'] = 600;

$ This-> load-> library ('image _ lib ');

For ($ I = 1; $ I <6; $ I ++ ){
$ Upload = $ this-> upload-> do_upload ('image'. $ I );
If ($ upload = FALSE) continue;
$ Data = $ this-> upload-> data (); // returns an array of all relevant information of the uploaded file.
$ Uid = $ this-> session-> userdata ('uid ');
$ UploadedFiles [$ I] = $ data;

If ($ data ['is _ image'] = 1 ){
// Initialize 170*170
$ ConfigThumb ['Source _ image'] = $ data ['full _ path']; // file path with file name
$ This-> image_lib-> initialize ($ configThumb );
$ This-> image_lib-> resize ();
// Initialize 600*600
$ ConfigLarge ['Source _ image'] = $ data ['full _ path']; // file path with file name
$ This-> image_lib-> initialize ($ configLarge );
$ This-> image_lib-> resize ();
}

// Insert the image information to the album table. the inserted file name is the source directory file name.
$ Picture = array (
'Filename' => $ data ['File _ name'],
'Albumid' => $ this-> uri-> segment ),
'Uid' => $ this-> session-> userdata ('uid '),
'Dateline '=> time (),
'Describe' => '',
'Click' => 0
);

$ This-> load-> model ('Album _ Model ');
$ This-> album_model-> AddPic ($ picture );
$ Picture = array ();
}
}

/* Transfer */
$ AlbumID = $ this-> uri-> segment (4 );
$ Backurl = site_url (). 'photo/editpic/album/'. $ albumID;
$ This-> session-> set_flashdata ('MSG ', 'image uploaded successfully .');
Redirect ($ backurl, 'refresh ');
}
}

The code is as follows:

Note the following:

1. to upload several files at a time, modify the parameters of the loop section in the form and controller.
2. album \ source is the Directory of the uploaded source image. large and thumb run $ this-> image_lib-> resize () twice.
3. if the thumbnail file name must be consistent with the album \ source directory, add the parameter $ config ['thumb _ marker'] = '';
4. $ picture this part of the array is saved to the database, you don't need to worry about it.

Upload 1. upload 5 images at the same time. 2. generate two thumbnails at the same time. 3. save them to the mysql controllers: upload. php file: the code is as follows :? Php class Uplo...
