How to return values to parent/caller page??

[baronmask]

Dear php Gurus,

suppose I have a form with a text box which require me to fill it with a value. I click in the text box and a pop up window showing up a list of choices, lets say like this:

01 Good
02 Fair
03 Bad

When I click 01 (or Good), I want the value (01) return to the text box on the caller/parent page and the pop up window then will close itself?

How can I do this with PHP?

Hello,
you can't do it directly in PHP, becouse PHP is a server-side language. For full interactivity with page users you need to use some client-side language, eg. JScript or VBscript. If open new window (popup) by javascript method window.open, you will be able to call some functions on opener window, e.g.:

PARENT WINDOW
<input type="text" name="testField">
<br>
<A HREF="javascript:window.open('new_window.html','nameOfNewWindow',width=300,height=300)">open window</A>

NEW_WINDOW.HTML
<SELECT ONCHANGE="top.opener.window.document.testField.value = this.options[this.selectedIndex].value; window.close()">
<OPTION>
<OPTION VALUE="ABC">ABC
<OPTION VALUE="DEF">DEF
</SELECT>

It's only an example. For more info I suggest you to read this: http://www.webreference.com/js/tutorial1/opener.html

Dear mlewczuk,
thank you a lot, it is a really... really... helpful hint. Using your clue I modify my script to combine with PHP and it goes well.

Thanks a lot.
