arrray中的變量值作為整數返回,但在codeigniter中需要字符串

[英]variable value in arrray is returned as an integer but needed string in codeigniter

大家好,我完全陷入了這個問題。

我想使用codeigniter中的字符串“rename”函數將我更改的文件的名稱添加到數組中,然后將該數組發送到模型,我可以將其提取並添加到我的數據庫中。

但是,當我這樣做時,我的數據庫中為文件名添加的值總是為'1'。

這是我的代碼,其中我上傳並存檔。

這是控制器類的一部分,文件名更改並添加到數組中

        $data = array('upload_data' => $this->upload->data()); // Get the file from the form userfile information
        $file = $data['upload_data']['file_name'];

        //hacky name generator
        $randomstring = random_string('alnum', 4);
        $filenew = rename($dir . $file, $dir . $id . '_' . $randomstring . '.jpg'); //basic php rename call, rename my upload now that upload finished

        // this array is all the other values from my form fields
        $data = array($this->input->post('comment'), $filenew);

        $configB['image_library'] = 'gd2'; // this code begins the thumbnail making process, from user guide
        $configB['source_image'] = $filenew;//$dir . $id.'.jpg'; // I am using $id for image name, which is my users id, comes from the session
        $configB['create_thumb'] = FALSE;
        $configB['maintain_ratio'] = TRUE;
        $configB['width'] = 300;
        $configB['height'] = 300;
        $this->image_lib->initialize($configB); 
        $this->image_lib->resize();

        $this->load->model('membership_model'); 
        // run my model which saves all this to the database, image name also ($filenew)   
        if($query = $this->membership_model->create_post($id,$data)) 
        {
            $data = array('upload_data' => $this->upload->data());
            $data['filename'] = $filenew; 
            $this->load->view('post_success_view', $data);

        }

這是模型

function create_post($id, $data) 
{
    //get data from array
            $content = $data[0];
    $filename = $data[1]; 

    // update database to track a new post.
    $new_post_insert_data = array(
        'content' => $content,
        'beer_down' => 0,
        'beer_up' => 0,
        'user_name' => $this->session->userdata('username'),
        'account_id' => $this->session->userdata('userid'),
        'file_name' => $filename
        );

    $insert_post = $this->db->insert('post', $new_post_insert_data);
    return $insert_post;    
}

如果你能幫助我在這里呆上幾個小時,請先謝謝你。

rename()更改系統資源的名稱,並返回Bool以獲得成功。 當你將布爾值true轉換為字符串時,你得到“1”。 如果要將名稱存儲在DB中,則應設置變量,即:

$new_name = $dir . $id . '_' . $randomstring . '.jpg';

然后調用重命名:

rename($dir . $file, $new_name);

並使用$ new_name插入數據庫。
