在我的html表单中我有两个文件输入字段
<div style="width: 125px; height: 35px; float: left; font-weight: bold; font-size: 16px;">
Image Large
</div>
<div style="width: 125px; height: 35px; float: left; margin-top: 15px;">
<input type="file" name="large_image" id="large_image"/>
</div>
<div style="clear: both;"></div>
<div style="width: 125px; height: 35px; float: left; font-weight: bold; font-size: 16px;">
Image Small
</div>
<div style="width: 125px; height: 35px; float: left; margin-top: 15px;">
<input type="file" name="small_image" id="small_image"/>
</div>
在我的控制器文件中我有两个上传小图像和大图像的功能。这两个函数由一个函数执行，如
private function insert_products() {
$this->upload_prodct_img_small();
$this->upload_prodct_img_large();
}
两个上传功能就是这样。
private function upload_prodct_img_large() {
$image_name = $this->get_image_name_uploade();
$config['upload_path'] = 'uploaded/large/';
$config['file_name'] = $image_name;
$config['overwrite'] = 'FALSE';
$config['allowed_types'] = 'png|PNG';
//$config['max_size'] = '1000';
//$config['max_width'] = '720';
//$config['max_height'] = '960';
$config['remove_spaces'] = TRUE;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('large_image')) {
$error = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('error', $error);
} else {
$error = 'Successfully Uploaded';
$this->session->set_flashdata('error', $error);
}
}
private function upload_prodct_img_small() {
$image_name_small = $this->get_image_name_uploade();
$config['upload_path'] = 'uploaded/';
$config['file_name'] = $image_name_small ;
$config['overwrite'] = 'FALSE';
$config['allowed_types'] = 'png|PNG';
//$config['max_size'] = '1000';
//$config['max_width'] = '180';
//$config['max_height'] = '240';
$config['remove_spaces'] = TRUE;
$this->load->library('upload', $config);
if (!$this->upload->do_upload('small_image')) {
$error = array('error' => $this->upload->display_errors());
$this->session->set_flashdata('error', $error);
} else {
$error = 'Successfully Uploaded';
$this->session->set_flashdata('error', $error);
}
}
在这两种情况下，我都将文件重命名为$ config数组中的单个文件名。
问题是这个。当我尝试上传两个文件时，只有“small_image”正在上传，而另一个文件总是丢失。
你可以看到我已经评论出宽度的高度和尺寸。因为如果我没有这样做，它会给我一个错误，说“你上传的文件超出了允许的高度或宽度”（类似的东西）。
我已经仔细检查过我上传的文件大小与允许的文件大小完全相同。
另一种情况是我做了类似的事。
private function insert_products() {
//$this->upload_prodct_img_small();
$this->upload_prodct_img_large();
}
然后上传大图片而不会出现任何错误。
找不到我做错了什么？

在第二个函数中加载上传库之前，只需初始化新的配置数组。
即。通过包含以下行来初始化$ config：
$this->upload->initialize($config);
行之前：
$this->load->library('upload', $config);
。
通常，在将新配置与库一起使用之前，您必须初始化新配置，否则将使用默认配置。在您的情况下，默认是您的第一个配置。

这是我使用的，我测试了它，它对我来说只是阅读评论。
set_time_limit(0);
$config['upload_path'] = './assets/uploads/pictures';
$config['allowed_types'] = 'png';
$config['max_size'] = '1000';
$config['width'] = 188;
$config['height'] = 187;
//load library with first config
$this->load->library('upload', $config);
if ( ! $this->upload->do_upload())
{
$error = array('error' => $this->upload->display_errors());
$this->view_data['system_message'] = $this->_msg('n',' '.$error['error']);
}
else
{
//if data has been uploaded successfully get the newly uploaded file and process
//this is the data for the newly uploaded file
$data = array('upload_data' => $this->upload->data());
//resize start
$source_path = $data['upload_data']['full_path'];
//new path i want to put the resized image
$target_path = './assets/uploads/thumbs';
//just create thumbs
$thumb['image_library'] = 'gd2';
$thumb['source_image'] = $source_path;
$thumb['new_image'] = $target_path;
$thumb['create_thumb'] = TRUE;
$thumb['maintain_ratio'] = FALSE;
$thumb['width'] = 100;
$thumb['height'] = 100;
$this->image_lib->initialize($thumb);
$this->image_lib->resize();
$this->image_lib->clear();
//resize image
$thumb2['image_library'] = 'gd2';
$thumb2['source_image'] = $source_path;
$thumb2['new_image'] = $data['upload_data']['file_path'];
$thumb2['create_thumb'] = FALSE;
$thumb2['maintain_ratio'] = TRUE;
$thumb2['width'] = 200;
$thumb2['height'] = 200;
$this->image_lib->initialize($thumb2);
$this->image_lib->resize();
$this->image_lib->clear();
//resize end
