codeigniter->上传空问题

Question

我收到以下错误：

Column 'thumbpath' cannot be null

我已经尝试过$thumb_info = $thumb_info = $this->image_lib->resize(); 然后在我的$data数组中将其设置为'thumbpath' => $thumb_info['create_thumb']但这会导致PHP错误

Fatal error: Call to a member function resize() on a non-object in addimage.php on line 60

我也很努力地将错误或成功消息发布到视图中：

视图

<?php
    //Setting form attributes
$formAddImage = array('id' => 'addImage', 'name' => 'addImage');
$imageImage = array('id' => 'userfile', 'name' => 'userfile', 'placeholder' => 'File Location*');
$imageDescription = array('id' => 'description','name' => 'description','placeholder' => 'Image Description*');
?>
<section id = "validation"><?php echo validation_errors();?></section>

<?php
if(!empty($success)) : ?>

<section id="validation"><?php echo $success; ?></section>

<?php endif; ?>

<?php
echo form_open_multipart('admin/addimage', $formAddImage);
echo form_fieldset();
echo form_upload($imageImage);
echo form_textarea($imageDescription);
echo form_submit('submit','Submit');
echo form_fieldset_close();
echo form_close();
?>`

    ); 
$this->image_model->addImage($data);

$this->data['success'] = 'Thank You, Your Image Has Been Uploaded';

模型

function addImage($data) {
    $this->db->insert('images',$data);
    return;
}

Answer 1

在第58行：

'thumbpath' => $file_info['create_thumb']

我不认为'create_thumb'是来自$ this-> upload-> data（）的有效字段

也许你想要：

 'thumbpath' => $config['new_image'].$this->upload->file_name  

好的-关于正确设置拇指路径的第二个问题，我认为您需要这样的东西：

$imagefullpath = $config['new_image'].$this->upload->file_name;
$path_parts = pathinfo($imagefullpath);
$imageextension = $path_paths['extension'];
$imagerenamed = $part_parts['dirname'].'/'.$path_parts['filename'].'_thumb'.$imageextension;

（未经测试，请确保您至少运行PHP 5.2）

让我知道结果如何。

Answer 2

我通过执行以下操作解决了此问题：

    $data = array(   
    'description' => $this->input->post('description', TRUE), 
    'fullpath' => $file_info['file_name'],
'thumbpath' =>$file_info['raw_name'].'_thumb'.$file_info['file_ext'] 
    );
