请帮助我解决问题。因此,为了在同一请求中执行多个上载,您可以使用类似以下内容更改CodeIgniter查看传入上载文件的方式:
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';
$config['max_size'] = '10000';
$config['max_width'] = '1024';
$config['max_height'] = '768';
$this->load->library('upload');
$errors = [];
$files = $_FILES;
$upload_count = count( $_FILES['userfile']['name'] );
for( $i = 0; $i < $upload_count; $i++ )
{
$_FILES['userfile'] = [
'name' => $files['userfile']['name'][$i],
'type' => $files['userfile']['type'][$i],
'tmp_name' => $files['userfile']['tmp_name'][$i],
'error' => $files['userfile']['error'][$i],
'size' => $files['userfile']['size'][$i]
];
$this->upload->initialize( $config );
// Use upload library for file validation
if( $this->upload->do_upload() )
{
// Upload was successful, do something ...
}
else
{
// Error: Upload Failed
$errors[] = $this->upload->display_errors('','');
}
}
$config['upload_path']='./uploads/';
$config['allowed_types']='gif | jpg | png';
$config['max_size']='10000';
$config['max_width']='1024';
$config['max_height']='768';
$this->load->library('upload');
$errors=[];
$files=$\u文件;
$upload_count=count($_FILES['userfile']['name']);
对于($i=0;$i<$upload\u count;$i++)
{
$\u文件['userfile']=[
'name'=>$files['userfile']['name'][$i],
'type'=>$files['userfile']['type'][$i],
'tmp_name'=>$files['userfile']['tmp_name'][$i],
'error'=>$files['userfile']['error'][$i],
'size'=>$files['userfile']['size'][$i]
];
$this->upload->initialize($config);
//使用上载库进行文件验证
如果($this->upload->do_upload())
{
//上传成功,请做些什么。。。
}
其他的
{
//错误:上载失败
$errors[]=$this->upload->display_errors(“”,”);
}
}
这也意味着您将HTML中文件输入的名称更改为userfile[]。因此,为了在同一请求中进行多次上载,您可以使用类似以下内容更改CodeIgniter查看传入上载文件的方式:
$config['upload_path'] = './uploads/';
$config['allowed_types'] = 'gif|jpg|png';

$config['max_width'] = '1024';

$this->load->library('upload');
$errors = [];
$files = $_FILES;
$upload_count = count( $_FILES['userfile']['name'] );
for( $i = 0; $i < $upload_count; $i++ )
{
$_FILES['userfile'] = [
'name' => $files['userfile']['name'][$i],
'type' => $files['userfile']['type'][$i],
'tmp_name' => $files['userfile']['tmp_name'][$i],
'error' => $files['userfile']['error'][$i],
'size' => $files['userfile']['size'][$i]
];
$this->upload->initialize( $config );
// Use upload library for file validation
