Re: [Phplib-users] oohForm text element with multiple attribute

[Nathaniel P. <np...@te...>]

There have been some problems with using JavaScript on form inputs that have
"[]" in their name before. Some excellent solutions can be found in the user
contributed notes in the PHP manual:
http://www.php.net/manual/en/language.types.array.php

Basically the solutions boil down to doing one of the following:

1) Use the alternate Javascript syntax to access the form, i.e.:
document.theForm.elements["myField[0]"].value

This will only work if each input has a unique name. In other words, if you
have multiple inputs and all of them are named "myField[]", this won't work.
However, this is also the most foolproof method of doing it, since it won't
break if you move the HTML form elements around, as with method #2. All you
have to do is make sure that OOHforms outputs an index number along with
each form name, so that it looks like
<input name="myField[$i]"...> where $i is a unique number for each form
element, instead of <input name="myField[]">

2) Use the generic JavaScript elements[] array to access it, i.e.:
for (i = 0; i <= frm.elements.length; i++) {
    document.theForm.elements[i].value
}

The disadvantage is that if you move your form elements around much, you'll
break your javascripts.

3) You might also experiment with using the HTML ID attribute to do it,
however I'm not sure if it will work:
<script language="javascript">
//UNTESTED JAVASCRIPT - Use at own risk
//Make sure your form elements are done like this:
//<input type="text" name="myField[]" id="myField1">
//<input type="text" name="myField[]" id="myField2">
//and so on
document.writeln(document.getElementById("myField1").value);
document.writeln(document.getElementById("myField2").value);
</script>

You will need to make sure that each HTML ID attribute is given a different
name. This one is almost like method #1, but you don't have to worry about
giving each element a unique NAME attribute.

I will leave a specific implementation within OOHforms as an excersize to
the reader, since I haven't bothered much with that particular class and
wouldn't know exactly where you'd need to modify it.
