codeigniter文件上傳失敗，沒有錯誤

Question

以下是通過codeigniter上傳多個文件的代碼，但這不起作用。 總是拋出錯誤“未選擇文件”

的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>

Java腳本

<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>

控制者

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

}

這給出了這樣的輸出。

            )

    )

）請建議如何上傳這些文件。

Answer 1

我建議先去File Uploading Class 。現在關於您的問題，因為我知道您沒有將文件字段的名稱傳遞給do_upload()方法。因此這是代碼中的修改，

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');
    }
