RE: [PHP] Confirm a Deletion

[snip]
The way the code is written, the record gets deleted immediately upon
clicking the submit button on page one.  Is there some way I can keep the
script on page two from executing until after I press the confirmation
button?
[/snip]

One of two ways, an intermediary PHP page that asks Are you sure? while
carrying the information forward, or a JavaScript pop-up confirmation dialog
box.

HTH!

RE: [PHP] Confirm a Deletion

2002-10-01 Thread John W. Holmes

Just create a middle page that stores the value of $area_todelete in a
hidden field.

input type=hidden name=area_todelete
value=?=htmlentities($_POST['area_todelete'])?

You YES button would submit it to the delete code you already have,
the NO confirmation button would send the user somewhere else, maybe
back to the choose area page. 

I hope that's not too confusing.

 Subject: [PHP] Confirm a Deletion
 
 I know this should be very simple, but I just don't get it.
 
 I want to delete a record from a mysql table, but prior to deleting
the
 record I want to receive an option to confirm the deletion.  On page
one
 (kb_areas_add.php) I have a form for inputting the field
(area_todelete)
 for
 the record I want to delete.  The form action goes to page two
 (kb_areas_delete) on which I am asked to confirm the deletion.  I want
to
 be
 able to press the delete button to delete the record, or the cancel
button
 to cancel the operation.
 
 The way the code is written, the record gets deleted immediately upon
 clicking the submit button on page one.  Is there some way I can keep
the
 script on page two from executing until after I press the confirmation
 button?
 
 Thanks for any suggestions.

Thanks guys.  The intermediate page scheme worked.

I added the hidden field like so because I couldn't get htmlentities to
work:

input type=hidden name=area_todelete value=?=$area_todelete?

I appreciate the help.

Just hope that no one submits a $area_todelete with an  in it,
otherwise they will be able to inject any kind of HTML/Javascript/etc
they want into the resulting page.
