select/option looping

[James Ponder <ja...@db.com>]

Hi,

Firstly, thanks for your help about headers/footers earlier, that was a great help - but I found out about EmbperlObject and now I'm using that, which is very nice indeed.  Embperl is really growing on me and I thank you for all the work you must have put in.

I have a new question - what is the Embperl way of doing:

@xyz = ('one', 'two', 'three');
$default = 'The default option';

                    <select name="sel" size="1">
                      <option value="default">[+ $default +]</option>
                      <option value="[+ $xyz[$row] +]">[+ $xyz[$row] +]</option>
                    </select>

i.e. to have a default?  The use of $row here causes my default to be replicated many times, and I get:

default
one
default
two
default
three

I don't want to prepend the default to my array because I want a different string to the value.  I could do:

                    <select name="sel" size="1">
                      <option value="[+ $xyz[$row] +]">[+ $xyz[$row] eq 'default' ? 'The default option' : $xyz[$row] +]</option>
                    </select>

But after you have a few extra cases like this it becomes messy, for example if I have several default and serveral data sources I am putting into this select.

It seems to me it would be nice if an <option> with a $row in it does not duplicate all of the contents of the <select> but only the contents of the enclosing <option>?


Best wishes, James

Yes, we have discussed this recently, and it really seems a good idea to
change this. It works the way it works for historical reasons, but since for
2.0 you have to changes a few things anyways when you upgrade from 1.3, this
would be a good time to change the behaviour and I guess the feature that
two options (or in case of tables rows/columns) should be repeated is very
seldom.
