无法使用Codeigniter将上传的图像路径存储在数据库中

Question

I read similar query on google, there I read about checking whether file is writable and then setting permissions using chmod() function, but I tried that too, it didnt work. I want to store the image path in database, and move the image to the uploads folder. The path of the image would be as : C:/xampp/htdocs/konnect1/uploads/Hydrangeas1.jpg On using chmod(), I get Warning as "Message: chmod(): No such file or directory". please help as what should I change now.

Controller page->admin_c.php Posting the function, where image upload code is written.

          public function create_event1()
         {
        if($this->input->post('counter') || !$this->input->post('counter'))
        {

            $count = $this->input->post('counter');
            $c = $count;
            //echo $c;          


            if($this->input->is_ajax_request())
            {
                $vardata    =   $this->input->post('vardata');
                echo $vardata;

            } 

            $g = $_POST['results'];

Answer 1

According to the error message, it seems PHP is unable to find the directory.

Please use PHP function is_dir() to first validate if PHP can recognize the path as a folder.

Once it returns true, you can proceed to use it.

Also in your upload path, you have started with / which would mean that your project is placed in root of OS and I don't think that location would be correct.

From the terminal cd to your project directory and run command pwd and get the current working directory and then use the proper upload path after taking into consideration the location of the project.
