我遇到了webcam plugin的问题。

我可以访问相机并拍照，但无法保存。当我click到record（Guardar Foto）时，它没有任何动作

             }
         });
        });


    </script>
</body>

现在我的模特

    <?php

class Fotos_model extends CI_Model{

public function gravarFoto($foto) {
    return $this->db->insert('fotos',array('foto'=>$foto));

}

public function getLastFoto() {
    return $this->db->order_by('id','desc')->get('fotos')->row()->foto;

}

}

和我的控制器

<?php

class Webcam extends CI_Controller{

public function __construct() {
    parent::__construct();
    $this->load->model(array('Fotos_model'));
}


public function index() {
        $this->load->view('webcam/index_view');
    }

    public function ajax () {
        $src = $this->input->post('src');
        $this->Fotos_model->gravarFoto($src);
        $foto = $this->Fotos_model->getLastFoto();
        $this->output->set_output ($foto);

    } 
}

Answer 1

语法错误：

末尾缺少分号

data = {src: src}

应该是

data = {src: src};

Answer 2

您的错误是因为字段ID必须是：key＆amp;自动增量：
