I'm adding a box to add / update post screen.

add_action( 'save_post', 'psd_upload_kaydet' );
add_action( 'add_meta_boxes', 'psd_upload' );
function psd_upload()
    add_meta_box("psd-upload", "Bir Dosya Upload Edin", "psd_upload_box", "post");
function psd_upload_box($post)
    echo "content here";
function psd_upload_kaydet($post_id)
    die($post_id); // for debugging, i'll explain it

There is no error while adding box, but normally, when post saved, add_action( 'save_post', 'psd_upload_kaydet' ); will pass post id as an argument to psd_upload_kaydet()

But it's not passing post it to psd_upload_kaydet() as an argument. I'm checking it die($post_id); , but it's returning just blank page.

In shortly, I need post id in psd_upload_kaydet() :)

die is an alias of exit and from php.net:

void exit ([ string $status ] )

If status is an integer, that value will be used as the exit status and not printed.

Try doing the following instead.

function psd_upload_kaydet($post_id)
    echo $post_id;
    die(); // for debugging, i'll explain it


  • die()'s parameter will be printed to page : codepad.viper-7.com/tA5Zsn

    I will not flame you for down voting my correct answer. Instead I will just assume you missed the part where I said integers are not printed. codepad.viper-7.com/wgrBDB

  • I vote down, because i'm trying die($post_id . " error"); and still getting error. I'll try it again. I'll clear downvote if you edit answer.

  • There is no need for me to edit my answer because it is correct. die($post_id . "error") will work too. If it doesn't, then you have a problem somewhere else. I'm down voting this question as it is a PHP issue not a WordPress issue, and should therefore be asked on stackoverflow.
