Codeiginter - do_upload“未选择文件”

Question

我正在尝试从所见即所得文本区域（TinyMCE）上传图像，但它不起作用，它给我错误“文件未选择”。

我使用的是多部分形式，它与其他“输入文件”冲突吗？

谢谢。

这是我正在使用的代码。

查看（.twig）

{{ form_open_multipart() }}
...
   <div class="form-group">
     <label class="col-sm-2 control-label">Texto</label>
     <div class="col-sm-10">
        {{ form_textarea('text',set_value('text') ? set_value('text') : post.text|raw,'class="form-control editor"') }}
        <input name="image" type="file" id="upload_img_wysiwyg" class="hidden" onchange="">
      </div>
   </div> 
{{ form_close() }}

控制器

public function upload_image_tinymce() {
   //Check whether user upload picture
   if (!empty($_FILES['image']['name'])) {
      $config['upload_path'] = ADDONPATH.'themes/escolamagica/img/escolamagica-blog/';
      $config['allowed_types'] = 'jpg|jpeg|png|gif';
      $config['file_name'] = $_FILES['image']['name'];
      $config['overwrite'] = TRUE;
      $config['max_size'] = '10240';
      $config['max_width'] = '10000';
      $config['max_height'] = '10000';

      $this->load->library('upload', $config);
      $this->upload->initialize($config);

      if ($this->upload->do_upload('image')) {
         $picture = str_replace('\\', '/', base_url().'img/escolamagica-blog/'.$_FILES['image']['name']);
      } else {
        echo 'CONFIG';
        var_dump($config);

        echo 'IMAGE';
        var_dump($_FILES);

        echo 'ERROR';
        $error = array('error' => $this->upload->display_errors());
        var_dump($error);
        die;

        $picture = '';
      }
   } else {
      $picture = '';
   }

   return $picture;
}

Javascript

function initImageUpload(editor) {
    // create input and insert in the DOM
    var inp = $('<input id="tinymce-uploader" type="file" name="pic" accept="image/*" style="display:none">');
    $(editor.getElement()).parent().append(inp);

    // add the image upload button to the editor toolbar
    editor.addButton('imageupload', {
        text: '',
        icon: 'image',
        onclick: function(e) { // when toolbar button is clicked, open file select modal
        inp.trigger('click');
        }
    });

    // when a file is selected, upload it to the server
    inp.on("change", function(e){
        uploadFile($(this), editor);
    });
}

function uploadFile(inp, editor) {
    var input = inp.get(0);
    var data = new FormData();
    data.append('image[file]', input.files[0]);

    $.ajax({
        url: BASE_URL + 'admin/blog/upload_image_tinymce',
        type: 'POST',
        data: data,
        processData: false, // Don't process the files
        contentType: false, // Set content type to false as jQuery will tell the server its a query string request
        success: function(data, textStatus, jqXHR) {
            console.log(data);
            editor.insertContent('<img class="content-img" src="' + data.url + '"/>');
        },
        error: function(jqXHR, textStatus, errorThrown) {
            if(jqXHR.responseText) {
                errors = JSON.parse(jqXHR.responseText).errors
                alert('Error uploading image: ' + errors.join(", ") + '. Make sure the file is an image and has extension jpg/jpeg/png.');
            }
        }
    });

您在表单上传和tinyMce图像上传中使用不同的索引。您的 html 表单具有名称为“image”的文件输入。但是您的 MCE ajax 文件上传的名称为“pic”。因此，在您的控制器功能中

upload_image_tinymce()

将

$_FILES['image']

替换为

$_FILES['pic']

在控制器中使用它：

public function upload_image_tinymce() {
   //Check whether user upload picture
   if (!empty($_FILES['pic']['name'])) {
      $config['upload_path'] = ADDONPATH.'themes/escolamagica/img/escolamagica-blog/';
      $config['allowed_types'] = 'jpg|jpeg|png|gif';
      $config['file_name'] = $_FILES['pic']['name'];
      $config['overwrite'] = TRUE;
      $config['max_size'] = '10240';
      $config['max_width'] = '10000';
      $config['max_height'] = '10000';

      $this->load->library('upload', $config);
      $this->upload->initialize($config);

      if ($this->upload->do_upload('pic')) {
         $picture = str_replace('\\', '/', base_url().'img/escolamagica-blog/'.$_FILES['pic']['name']);
      } else {
        echo 'CONFIG';
        var_dump($config);

        echo 'IMAGE';
        var_dump($_FILES);

        echo 'ERROR';
        $error = array('error' => $this->upload->display_errors());
        var_dump($error);
        die;

        $picture = '';
      }
   } else {
      $picture = '';
   }

   return $picture;
}
