The example of this article describes the method of generating multiple thumbnails by thinkphp3.2.2 implementation. Share to everyone for your reference.

The implementation methods are as follows:

Copy Code code as follows:

Public Function Dz_upload () {//Upload multiple thumbnails upload 2 thumbnail images
if (Isset ($_files[' ori_img ')) {
$upload = new \think\uploadfile ()///materialized upload class
$upload->maxsize = 3000000;//Set attachment upload size C (' upload_size ');
$upload->savepath = './public/uploads/'. $path; Set up attachment upload directory
$upload->savepath = './public/uploads/'. ' thumb/'; Set up attachment upload directory
$upload->allowexts = array (' jpg ', ' gif ', ' PNG ', ' jpeg '); Set Attachment upload Type
$upload->saverule = ' time ';
$upload->uploadreplace = true; Whether a file with the same name is overwritten
$upload->thumb = true; Do you want to do thumbnail processing of uploaded files
$upload->thumbmaxwidth = ' 100,300 '; Thumbnail processing width
$upload->thumbmaxheight = ' 50,150 '; Thumbnail processing height
$upload->thumbprefix = $prefix; Thumbnail prefix
$upload->thumbprefix = ' m_,s_ '; Produce 2 thumbnail pictures
$upload->thumbpath = './public/uploads/'. $path. Date (' Ymd ', Time ()). '/'; Thumbnail save path
$upload->thumbpath = './public/uploads/'. ' thumb/'. Date (' Ymd ', Time ()). '/'; Thumbnail save path

$upload->thumbremoveorigin = true; Delete the original picture after uploading the picture
$upload->thumbremoveorigin = false; Delete the original picture after uploading the picture
$upload->autosub = true; Whether to save pictures with subdirectories
$upload->subtype = ' Date '; Sub-directory Save rule
$upload->dateformat = ' YMD '; Child directory Save rule is date time format

if (! $upload->upload ()) {//Upload error message
echo json_encode (' msg ' => $this->error ($upload->geterrormsg ()), ' status ' => 0));
else {//upload successfully get uploaded file information
$info = $upload->getuploadfileinfo ();
$picname = $info [0][' Savename '];

$picname = explode ('/', $picname);
$picname = $picname [0]. '/' . $prefix. $picname [1];
$picname = $picname [0]. '/' . ' _hz '. $picname [1];
Print_r ($picname);
echo json_encode (' status ' => 1, ' msg ' => $picname));
}
}
}

Call Method:

Copy Code code as follows:

$k =a ("Index"); Koo method key to call Controller index (Lish)

$slt = $k->dz_upload ();

Notice here that thinkphp3.2.2 does not have a uploadfile,uploadimage class, you need to extract it from the expansion pack and then add them to the Thinkphp\library\think directory.
