Extracting form info 2

[skiflyer]

I'm afraid this may be an HTML question but maybe not...

so here's what I have...

<select name=&quot;test1&quot; size=&quot;20&quot; multiple>
  <option value=&quot;1&quot;>One</option>
  <option value=&quot;2&quot;>Two</option>
</select>

within a posted form, then the page jsut does a 

echo &quot;<pre>&quot;;
print_r($_POST);

the problem is, I only get one of the selections if I highlight them both, any ideas how to fix this?

Thanks,
Rob

Set the name to [tt]test1[][/tt] ;-).

After all checkboxes I've used that on you'd think I would've thought of that. Thanks daniel!

Now to mix it with my javascript....

Anyone know if there's another way to do this?

The problem is, javascript won't let me access a form element named

<select MULTIPLE name=&quot;test1[]&quot;>
...
</select>

but php doesn't seem to have the information if I do it without the []'s.

In JavaScript you can access the array memebers like this:

CONTROL.options

You can check for
CONTROL.options.selected = true;
to see if it was selected. There is of course also a value:
CONTROL.options.value;

Oops - should have previewed this:

The markup removed the square brackets with the index:
You need:

CONTROL.options[i].selected = true;

 

[skiflyer]

Right, but CONTROL needs to be the name of the form element right?

So in my example, without the brackets I access

document.formname.test1.options[i].selected

however, I can't seem to access

document.formname.test1[].options[i].selected

Hmmm, now that gives me an idea...

So that so pointed me in the wrong direction, but still to the solution (go figure).

The way I did it is quite simple...

<select MULTIPLE name=&quot;test1[]&quot; id=&quot;test1&quot;>
...
</select>



now because of the [] I can use the array in PHP and because of the id I can use javascript.  Thanks for the inspiration.

So you can reference the element in JavaScript as

document.formname.test1

?

Yes, after limited testing in IE 6.0 and Mozilla 1.4a, I seem to be getting the best of both worlds, namely

document.formname.test1 in JavaScript and
$_POST["test1"][]; in php

You've solved a similar problem I've been having. So I'm going to give you a star.
