RE: [PHP-DB] Pop up are you sure...
You're so negative, Jason. :) Long answer, Dave, it wouldn't be wise to do this via Javascript. Javascript can be turned off and also varies from browser to browser (like any client-side language/scripting), so this raises an issue of reliability. You may be able to do it if you're working on an intranet where you know that all users have the same browser, have Javascript turned on, and don't have access to turn it off, OR if this is for your own use and you don't want to make it screw up. Otherwise, it might be a nice feature, but you shouldn't rely on it. If you WERE going to do it, I would have your main form have a hidden input called Confirm and set it to a value of 1. Then, have a Button (not a submit button) use Javascript to open a new browser/popup window (you can format it to look like a regular Yes/No windows popup box). Have the Yes I-want-to-delete-this-record button change its parent window's form and change the Confirm input's value to 0 and submit the parent window's form in order to delete the record. Have the No button just close the popup/new window. Now, on the page that actually deletes the record, first check the Confirm variable. If it is set to 0, then you can figure that the Javascript set it to 0, and you can go ahead and delete the record without asking. Otherwise, show a regular HTML screen that asks if you really want to delete this record (no Javascript this time), so you can be covered if Javascript gets turned off. This is by no means a fool-proof method, and you should think carefully through all this before implementing a Javascript solution, but I find that there are better methods with PHP. For instance, you can have 3 checkboxes side-by-side that can act as the yes-I-really-really-want-to-delete-this-record safety. PHP can check to see if all 3 checkboxes were checked, and then you can know that the user was intentionally trying to delete that record, and you can go ahead and delete it - no Javascript needed. :) As far as the Javascripting goes, though, I would check out some JS forums for help on how to set up the actual scripting part of the popup box. But, as Jason probably was thinking, Javascript is never a very good thing to use with things that are delicate, fragile, or valuable in any way. It's like hiring an ex-thief to help you move - you can never be SURE that everything's going to be there in the end. - Jonathan -Original Message- From: Jason Wong [mailto:[EMAIL PROTECTED]] Sent: Monday, April 01, 2002 12:45 AM To: [EMAIL PROTECTED] Subject: Re: [PHP-DB] Pop up are you sure...

Re: [PHP-DB] Pop up are you sure...
Hello!!
What I was able to do was this
On every form page I have, I have a checkbox that is labeled Ok To
Save, that the user would check or not..
I would then pass that variable to the next page and check to see if the
value was true or not...
If it is true then it would continue to insert the data into the
database...
If not then it would display the pop up messages
The code looks something like this on the parse page.(in my case it
is the insert3.php file)
?php
if (empty($save)){
?
script language=JavaScript
!--
function MM_popupMsg(msg) { //v1.0
alert(msg);
}
//--
/script
/head
body bgcolor=#FF text=#00 onLoad=MM_popupMsg('Hello!!
You Forgot to check---OK TO SAVE??---. This check is for when you
accidently hit return or enter...This will keep a Database
Happy!!!\n\nThank youADMIN')
?
echo (Click you back button please!!! We Have a Problem!!\n);
echo (/body\n);
echo (/html\n);
exit();
}
require (functions/java.inc);
echo (/HEAD\n);
echo (BODY BGCOLOR=#FF LINK=#FF VLINK=FF ALINK=00FF00
Text=#00);
?
It will popup a messages about not checking that checkboxAnd tell
you have an error...
I too messed around trying to just using PHP, but I gave up using just
PHP, Javascript plays nice with PHP anyway!!

Re: [PHP-DB] Pop up are you sure...
Hi all, Thank you all for you advice. I am aware of the two ways of achieving the required result ie: JS and extra button built into my script. But wouldn't it be nice to have a class or function we could all use built in to php that would let us do this. C,C++,Delphi and JS allow you to do this. I have come across various probs with JS on client systems so I shy away from it. Again thank you all for your advice.
