[Frage] Searching help for creating web-interface for a packege

[RomMon]

I’m looking for some help with a web-interface challenge where the number of fields for a specific parameter is dependent on an earlier specified (and saved) parameter. What I’m looking for is a variable with another variable appended.

i=1
while [ $i -le $NDAS_NETDISKPARTITIONS1 ]; do
        cat << EOF
<tr>
        <td>Mount command partiontion nda$i:</td>
        <td><input type="text" name="mountinstruction$i" size="2" maxlength="2" value="$(html "$NDAS_MOUNTINSTRUCTION$i1")"></td>
</tr>
EOF
        let i++
done

It is the part html "$NDAS_MOUNTINSTRUCTION$i1" that is not working.

This is similar to what is asked here: http://stackoverflow.com/questions/...d-variable-names-from-other-variables-in-bash
Both suggestions ${!variable} or an array don’t seem possible with busybox shell scripts.

ndas.cfg:

Are there options available or other alternatives?

Hi Romon.

I think this should work: http://lists.busybox.net/pipermail/busybox/2002-August/040763.html

Hi Oliver,

Yes this works. Thanks a lot!


The variable part of the eval instruction looks to only allow single character variables (e.g. the =\$$v part).

From davfs2.cgi I found another possible option that could be used also. This is using javascript.
