Multiple Selects

[carlg]

I want to do a multiple select like this where the user can select multiple items

 

<SELECT NAME="abc" MULTIPLE>
<OPTION VALUE="A">A
<OPTION VALUE="B">B
<OPTION VALUE="C">C
<OPTION VALUE="D">D
</SELECT>

 

 

How do I reference these variable in code or the form that does the processing?

 

Thanks for the info

Carl

Depening on whether you use "method=post" or "method=get" in your <form> tag, the value of the selected option would be in $_POST['abc'] or $_GET['abc'], respectively.

But, what if the user selects 2 options?

 

[carlg]

I will be using $_POST

change name property to "abc[]"

and then how is it referenced in the processing script?

 

For exmaple if I do a count() on the incoming array and the user selected 2 options

 

Will my count be 2 or 4?

 

[lemmin]

count($_POST['abc']) should be the number of fields with the name "abc[]" that were submitted.

Great, thanks for the help.

 

I got everything working besides 1 thing.

 

How do you get that variable to work in a Javascript?

 

I have something like this

 

<SELECT NAME="abc[]"></SELECT>

 

How can I refer to abc in a javascript?

Give it an id="abc" and use document.getElementById()

 

You can also try:

document.formName["abc[]"]
