我正在尝试上传图片并调整它们的大小,到目前为止上传工作还有拇指指甲图像的创建.但我不能让原始图像调整大小.所有发生的事情是文件以原始大小直接上传到文件夹.我想我正在尝试将此图像调整大小然后覆盖最初上传的文件.
这是我的代码,我错过了什么:
//Initialise the upload file class $config['upload_path'] = './image_uploads/'; $config['allowed_types'] = 'jpg|jpeg|gif|png'; $config['max_size'] = '6048'; $this->load->library('upload',$config); $userfile = "_upload_image"; //check if a file is being uploaded if(strlen($_FILES["_upload_image"]["name"])>0){ if ( !$this->upload->do_upload($userfile))//Check if upload is unsuccessful { $upload_errors = $this->upload->display_errors('',''); $this->session->set_flashdata('errors','Error: '.$upload_errors); redirect('admin/view_food/'.$food->course_id); } else { //$image_data = $this->upload->data(); ////[ THUMB IMAGE ] $config2['image_library'] = 'gd2'; $config2['source_image'] = $this->upload->upload_path.$this->upload->file_name; $config2['new_image'] = './image_uploads/thumbs'; $config2['maintain_ratio'] = TRUE; $config2['create_thumb'] = TRUE; $config2['thumb_marker'] = '_thumb'; $config2['width'] = 75; $config2['height'] = 50; $this->load->library('image_lib',$config2); if ( !$this->image_lib->resize()){ $this->session->set_flashdata('errors',$this->image_lib->display_errors('','')); } //[ MAIN IMAGE ] $config['image_library'] = 'gd2'; $config['source_image'] = $this->upload->upload_path.$this->upload->file_name; //$config['new_image'] = './image_uploads/'; $config['maintain_ratio'] = TRUE; $config['width'] = 250; $config['height'] = 250; $this->load->library('image_lib',$config); if ( !$this->image_lib->resize()){ $this->session->set_flashdata('errors','')); } } }
