编码器文件上传失败，没有错误 - codeigniter file upload failure with no error

codeigniter file upload failure with no error

以下是通过codeigniter上传多个文件的代码，但这不起作用。它总是抛出错误"file not selected"

HTML

<form name="form1" method="post" enctype="multipart/form-data" action="<?php echo base_url(); ?>index.php/dashboard/upload">
<table class="custom">
    <tr> <th>Title</th> <th>Image</th> </tr>
    <tr><td><input  type="text" name="title[]" id="title1"/></td>
    <td><input type="file" name="userfile[1][]" multiple id="userfile1" /></td>
    <td><input type="button" id="addbutton" value="Add More"></td></tr>
</table>
<table class="custom1" id="repeat-div"></table>

Javascript

<script>
  $(document).ready(function(e) {
    var i = $('#repeat-div').size();
    var j = i+1;
  $('#addbutton').click(function(){
    $('<tr><td><input type="text" name="title[]" id="title'+j+'"/></td><td><input type="file" id="userfile'+j+'" name="userfile['+j+'][]" multiple /></td></td></tr>').appendTo($('#repeat-div'));
++i;
j++;
});
});
</script>

控制器

function upload(){
  print_r($_FILES);exit;

}

输出如下:

    )

)请建议如何上传这些文件

我建议先进入文件上传类。现在关于你的问题，我知道你没有将文件字段的名称传递给do_upload()方法。这是你代码中的修改，

foreach($_FILES['userfile']['name'][$i+1] as $file){
        //your logic
        if ( ! $this->upload->do_upload('images')){    
          $error = array('error' => $this->upload->display_errors());
        exit; }
        else
        redirect('dashboard/failure');
    }
