Passing value to a popup...

adi

I know this is more javascript related than php, but i thought someone could help me.
I have this form with 2 text boxes. In the first one , the user can insert the supplyer name. Next to the second text box i have a link . I want to be able to click the link an to show a popup with products only from the supplyer entered in the first text box.
My problem its not the database part or the php, but how do i pass the value of the first text box and send it .
Thanks!

Make the link a javascript link, and pull the value of the first text box (something like "document.theform.supplier.value"). Append that value as a get request for the URL for the popup box (like "http://www.yourserver.com/appdir/popup.php?value=Acme%20Supply%20Company").

Your popup page can then use that value with $_GET['value'] and do a lookup to your database to grab the data, or do whatever you need to do.

I suggest that instead of a text box, you use a dropdown select box, so that users can only select a valid company. Then all you have to do is pass the company id to the popup box, and you won't get bad popups due to misspellings.

It's a little more complex grabbing the value with Javascript [value = document.theform.supplier.options(document.theform.supplier.selectedIndex).value], but it's a much more reliable method, IMO.

Thank you BuzzLY. I'm just getting started with javascript. Could you show me how to do this?

Something like this. It's untested, so I don't warranty against bugs. If you want a good javascript reference, go to www.devguru.com. Go here for information about window.open (including the options you'll want to use).

<script type="text/javascript">
<!--
function popup(val) {
  url = "/dir/yourpopup.php?value=" + val;
  popWindow = window.open(url,"Suppliers","<options go here>");
}
//-->
</script>
<form id="myform" method=post>
<input type="text" name="suppliers" value="">
&nbsp;<a href="#" onclick='popup(document.theform.suppliers.value);'>
View Supplier</a>
</form>

Good Luck!

If i may add to this, i do have the same dilema in a way.. except for two things..

1) I open a pop-up from Flash
2) I need to pass variables via POST

Pop up from flash is no problem.. apending the GET variables to the link isnt a problem either.. but i cant seem to find a way to send using POST method.. 🙁

ANy ideas?

In your case, a pop up may not be possible. But you can add a target="_blank" to your form tag so the submit opens a new window

I'm sorry, you have misunderstood my question sir.. As stated above, i've achieved the popup from flash already , as well as sending variables via GET method. it's just a simple javascript calling method..

But now, i just need to send via post..

Any ideas?

what's the problem with GET? they can't see the variables anyway, the user wont even know they're there.

Hi Moonglobe:

1) As you may probably know, there is a limit to the characters that can be appended to the URL (GET METHOD) 200 plus characters? I forgot, but i know it is limited... my Flash Application Form would carry a question and answer portion as well, so you can imagine how big the data i need to pass.

2) In flash, you can pass variables easily by just specifying:

loadVariables("script.php",this, "POST");

This function gathers all the variables on a specified level and sends it to script.php... I dont want to have to manually appened all the variables to the link...
