Php implements Image Upload and cropping Based on CodeIgniter,

This article provides examples of codeigniter image uploading, cropping, and controller classes for your reference. The specific content is as follows:

<? Phpdefined ('basepath') OR exit ('no direct script access allowed'); class Index extends MY_Controller {function _ construct () {parent :__ construct (); $ this-> load-> helper (array ('form', 'url');}/*** homepage */public function index () {$ this-> load-> view ('upload _ Form', array ('error' => '');} public function do_upload () {$ config ['upload _ path'] = '. /data/uploads/'; $ config ['allowed _ types'] = 'gif | jpg | Png '; $ config ['max _ size'] = 100; $ config ['max _ width'] = 1024; $ config ['max _ height'] = 768; $ this-> load-> library ('upload', $ config); if (! $ This-> upload-> do_upload ('userfile') {$ error = array ('error' => $ this-> upload-> display_errors ()); $ this-> load-> view ('upload _ Form', $ error );} else {$ data = array ('upload _ data' => $ this-> upload-> data ()); $ this-> load-> library ('image _ lib'); list ($ width, $ height) = getimagesize ($ data ['upload _ data'] ['full _ path']); $ config ['image _ library'] = 'gd2 '; $ config ['source _ image'] = $ data ['upload _ data'] ['full _ path']; $ config ['maintain _ ratio '] = TRUE; if ($ width >=$ height) {$ config ['master _ dim'] = 'height ';} else {$ config ['master _ dim'] = 'width';} $ config ['width'] = 180; $ config ['height'] = 180; $ this-> image_lib-> initialize ($ config); $ this-> image_lib-> resize (); $ config ['maintain _ ratio '] = FALSE; if ($ width >=$ height) {$ config ['x _ axis '] = floor ($ width * 180/$ height-180)/2 );} else {$ config ['y _ axis '] = floor ($ height * 180/$ width-180)/2 );} $ this-> image_lib-> initialize ($ config); $ this-> image_lib-> crop (); $ this-> load-> view ('upload _ success ', $ data );}}}

The above is all the content of this article. I hope it will help you learn php programming.
