> Subject: [PHP-DB] Editing DB entries via form
>
>
> What I have is an extremely scaled down version of a news DB.
>
> What I am not experienced in doing is the following:
>
> I want to have a page, say 'myEditNews.php'--and it will list
> the news items in the database with a checkbox and an edit button.
> The check box will be used for marking news items to delete.
> The edit button is obvious :).
>
> HOW:
>
> Say a person checks the 1, 5, and 9 check boxes and hits
> delete. How do I know in the myEditNews.php file that those
> particular boxes were checked?? When I figure this out, I
> will use a loop to delete the news items one at a time from
> the database (unless there is a better way).
>
> My understanding of check boxes is that they are not sent
> from the form unless they are checked.
>
> Here's what I have so far:
>
> 1) Use hidden fields as flags. All hidden fields have same
> name so that when they are submitted to PHP they go into an
> ordered array.
> 2) The corresponding checkbox fields will be checked. The
> value of the checkbox will have the news item DB primary key
> ID to delete on.
>

> == 0) { document.myForm.newsItem[".i."].value = 1 } else {
> document.myForm.newsItem[".i."].value = 1; }'>";
