For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Opening a new window from a form

Posted by Chris_Isaac (Chris Isaac), 10 May 2006
Hi

Bit stuck at the moment, What I would like to do is open a new window when a button on a html form is pressed.  I've looked at window.open function in Javascript which I can get to work on its own, but can't implement it into my existing script.  Here is the bit of the existing script:

Code:
$other = ($row[active] > 0) ? "<form action=\"http://www.theaccommodationfinder.co.uk/sites/$row[hid].php4\" method=get>".
           "<input name=hid type=hidden value=".$row[hid].">".
           "<input type=submit value=\"Further details for $row[name]\"></form>     " : "";



Which basically displays a "Further information" button if the site is live, then opens a page relating to the hotel.

Not sure how to get Javascript to fit in there, any ideas please?

Thanks.

Add  target=wname to your <form> tag if you want to target to a window called wname, or add target=_blank if you want to create a new window every time.

Perfect.  Thanks.

Sorry, another problem.  I didn't want any toolbars or address bars so I changed to the following:

Code:
     $other = ($row[active] > 0) ? "<form method=get onSubmit=\"window.open('http://www.theaccommodationfinder.co.uk/sites/$row[hid].php4?hid=$row[hid]' ,'', 'top=50, left=50, width=700, height=700, scrollbars')\">".
           "<input name=hid type=hidden value=".$row[hid].">".
           "<input type=submit value=\"Further details for $row[name]\">            
           
           </form>   " : "";



Which does exactly what I want, in terms of the child window, displays the information correctly without toolbars, etc.

The problem is when the form is submited it changes the main page, and I don;t know why.  The following link is what I'm taking about, if you hit the 'Further details' button you'll see what I mean:

http://www.webbreaks.co.uk/townsearch.php4?nexty=2&town=Newport&county=%20Gwent

Have I missed anything?

Thanks.

In technical terms , the Javascript seems to be refreshing the current window with the same parameters as you pass to the new window too.  Alas, like you I can't see why and I don't know enough JavaScript to make an educated guess either, I'm afraid.   Chris - in your shoes I would continue testing, tweaking, breaking and refixing and then see if I could make some sense of what I had learnt!

Funny enough I was just loging on to say I've found the same thing.  The main page's parameters are changing for some reason, been playing for a while but not quite got it yet...  I'll not let it beat me....

Done it.  

Changed the method to POST instead of get thats done the trick.  

Thanks for your help anyway.

Cheers.
