i tried file upload code but i am confuse where to place image name and that i have given inside input type file.
i comment out this code
// $file_name = pathinfo($tmp_name ,PATHINFO_FILENAME).time().".".pathinfo($tmp_name ,PATHINFO_EXTENSION);
// $file = $_FILES['your_meta_field']['tmp_name']['image'];
i am fresher at wordpress plugin development and this is new for me.
i seen soo many solution like there is function named wp_get_attachment_image located at plugin handbook.
with this code my insertion of image and other data is working successfully but image when i update then it says no image available i want my previous image name when i edit any post.
also it is not worked at fronend due to the reason of not properly image is stored.
i could not find my uploaded image inside upload folder.
here is my code :
