Question

嘿伙计我在codeigniter视图中使用此表单，我想知道如何上传此表单中的图片。

<form action="<?php echo site_url('Product/product_form'); ?>" method="post">      

  <h2> Cadeau aanbieden</h2>

  <table class="aanbieding-cadeau">
    <tr>          
      <td><?php echo form_input(array('id'=>'product_naam', 'name'=>'product_naam', 'placeholder' => '1. Naam van het cadeau', 'size'=>25));?></td>
    </tr>
    <tr>         
      <td><?php echo($selectField);?></td>
    </tr> 
    <tr>       
      <td><?php echo form_input(array('id'=>'ophaal_plaats', 'name'=>'ophaal_plaats', 'placeholder' => '3.Kies een stad', 'size'=>25));?></td>
    </tr>
    <tr>          
      <td>
       <?php echo form_input(array('id'=>'product_foto', 'name'=>'product_foto', 'placeholder' => '3.Upload foto', 'size'=>25));?></td>
    </tr>
    <tr>        
      <td><?php echo form_textarea(array('type'=>'textarea','id'=>'product_beschrijving', 'name'=>'product_beschrijving', 'placeholder' => '5. Vertel iets over dit cadeau..', 'size'=>25));?></td>
    </tr>
    <tr>          
      <td><button type="submit" class="btn btn-primary">Cadeau aanbieden!</button>
     </td>
    </tr>     
  </table>
</form>

所以不是这个输入字段：

 <?php echo form_input(array('id'=>'product_foto', 'name'=>'product_foto', 'placeholder' => '3.Upload foto', 'size'=>25));?>

我想选择一张图片并将其发布到我的数据库中。有人能帮我吗？谢谢！

----＆gt;使用codeigniter进行图像上传
----- Codeigniter为图像上传提供内置库在控制器中写入上传代码的图像我的控制器名称User.php＆amp;在这里我加载codigniter'image_lib'libadrary

首先在视图文件中的表单中添加 enctype =“multipart / form-data” 将其添加到控制器

中

if($_FILES["image-file"]["size"] != 0){
        $this->load->model('Upload_model');
        $path= './uploads/images';
        $img = $this->Upload_model->image_upload($path, "", '', '', '',"image-file");
    }
if(!is_array ($img)){
   $this->db->insert('your_tbl',array("image"=>$img));
}else{
print_r($img);
}

制作模型或将其粘贴到现有一个

public function image_upload($upload_path, $max_width, $max_height, $min_width, $min_height, $filename)
{
        $config['upload_path'] = $upload_path;
        $config['file_name'] = date('Ymd_his_').rand(10,99).rand(10,99).rand(10,99);
        $config['allowed_types'] = "gif|jpg|png|jpeg|pdf|docx|JPG|JPEG|PNG";
        $config['overwrite'] = FALSE;
        $config['max_size'] = '0';
        $config['max_width']  = $max_width;
        $config['max_height']  = $max_height;
        $config['min_width']  = $min_width;
        $config['min_height']  = $min_height;
        $config['max_filename']  = '0';
        $config['remove_spaces']  = FALSE;

        $this->load->library('upload', $config);
        $this->upload->initialize($config);
        if ( ! $this->upload->do_upload($filename))
            {
               //return $this->upload->display_errors();
             return $error = array('error' => $this->upload->display_errors());
            }
        else
            {
                $data = array('upload_data' => $this->upload->data());
                $config['source_image'] = $config['upload_path'].$data['upload_data']['file_name'];
                $config['quality'] = '100%';

                $this->load->library('image_lib', $config);
                return $data['upload_data']['file_name'];
            }
unset($config);
$this->image_lib->clear();
}
