probably simple question...

Hi,
I have a $var1 in my php file, a <select> combobox inside a form in my template html file.
I would like to post from the html file the "selectedIndex" of the combobox.
If I use the regular $_POST['...'], I get the value (text) of the selection, although I need the index...
I think it shouldn't be too difficult for you gurus out there...

Hi,

This is not about TBS. A form can only pass the value of a selected item in a combobox. If you need the index, and if this index must be diffrent from the value, then you have to het it using Javascript and save it into a hidden HTML field.

It's easier for everyone to undestand you and to help if you post your PHP and HTML template code ;)

This example

is executed in TBS like this

Sorry for the typo...
Should be

Thanks for your help guys,
I'll try to be clearer:
I have a <select> in my html. I can do, for example :
<code>
onchange="alert(document.getObjectByID('selID').selectedIndex)"
</code>
in it's attribute, and see the selected index.
my question was, how do I set variable (defined in the php file) to hold this data ?
something like
<code>[var.theIndex] = <script>document.getObjectByID('selID').selectedIndex</script></code>

The problem is not really clear to me,
but maybe You mean something like:
or simply something like:
?
I hope my comment helps a little

alright, this far I managed to go...
but I don't want to use ALERT - I want to get this value injected into one of my vars on the php page
thanks...

Hi,

You simply can't get it's value injected into a php variable unless you comunicate with the server. The html file is on the client's browser, that's why alert, as a javascript command, works. If you need to onchange event to do something on server side without posting the form, you have to write js to request a page from the server either by using location.href="..." or through some ajax communication.

As a side note, if you are not using a customized function that extends document object or a javascript library that does that, document.getObjectById will not work on most (if any) browsers. The correct code should be alert(document.getElementById('selId').value), or as an inline js simply onchange='alert(this.value)'.

that's the logic I was aiming...
cheers, mate
thanks
