php/javascript code, Anyone could help me?

Quevas

Hi !
With this code I would pass the boolean value of 'jsanswer' by get method, but it doesn't work.
I mean, when I click on 'ok' or 'cancel' on the confirm box, the value of jsanswer in the URL is always null.
It seems like submit() doesn't work.
What's wrong?

Thanks in advance.

<?php
if ($submit)
{
echo "<script language=javascript>
myform.jsanswer=confirm('Send?')
myform.submit()
</script>";
}

You dont have a value assigned to the hidden field you cannot make the submit value automaticallt become the value of jsanswer.

What exactly are you trying to do ?

<input type="hidden" name ="jsanswer">

I would assign the result of the confirm box (ok or cancel - 1or 0) to jsanswer and then pass it, by 'get' or 'post', to the same php page.
This is a method to pass javascript variables to php, I think...

OK, I see what you are trying to do, I think you may need to do it like this:

I havnt tested this, but it should give you my idea.

Yes, It's like the code I wrote, but without any submission jsanswer is always null in the URL.

... Anyway, thanks for the responses.

I dont think you understand what is happening here, you don't actually use PHP to do the validation you only you Javascript, the validation is done in the client side in real time (before the actual form is submitted), the javascript steps in before the form get passed and does the validation. you would construct the page as follows:

<html>
... MY HTML PAGE ...

hope you understand this.🙂

OK, I understand now... :p
