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',''));
}
}
}
您是否尝试将此添加到配置选项中
$config['overwrite'] = TRUE;
这应该可以解决问题.
根据文件
If set to true,if a file with the same name as the one you are uploading exists,it will be overwritten. If set to false,a number will be appended to the filename if another with the>same name exists.
