feel kind of foolish posting this.. but i can't seem to figure it out for
now..
Here's a way to tackle this kind of thing in the future:
Divide and Conquer.
print_r($foo) prints out a BUNCH of stuff.
Focus only on the outer layer:
i have an array, i can do a print_r($foo) and get the following:
Array
(
[bookmark] = 1
[facets] = Array
.
.
.
Then simply do:
print_r($foo['facets']);
Now you can ignore a bunch of crap you don't care about.
Focus on the outer layer and begin again:
Array
(
[0] = Array
(
[lastname] = form id=facet-lastname
input type=hidden name=list value= /
input type=hidden name=offset value=0 /
input type=hidden name=orderBy value=username /
input type=hidden name=sort value=asc /
strongName:/strong
input type=text name=_lastname value= style=width: 125px /
input type=submit value=Search /
/form
}
Okay, now we have:
print_r($foo['facets'][0]);
Array
(
[lastname] = form id=facet-lastname
input type=hidden name=list value= /
input type=hidden name=offset value=0 /
input type=hidden name=orderBy value=username /
input type=hidden name=sort value=asc /
strongName:/strong
input type=text name=_lastname value= style=width: 125px /
input type=submit value=Search /
/form
}
Finally, print_r($foo['facets'][0]['lastname'] is your answer.
It won't always be [] -- If you are using objects you might need - in
there somewhere.
Figuring out where gets a lot easier if you focus on the Big Picture --
only the outer layer of your data structure, and drill down.
If at some point you know you need *ALL* the elements of an array, that's
easy enough.
That's the point at which you put in a loop to walk through them.
BUT
During your development, write the loop, see that it dumps out all the
elements, or at least a whole lot of stuff, and then stick an exit; at
the end, and focus on JUST the first element to tear that apart.
You can take the exit; out when you are all done, and it will work for all
the elements, assuming your data is well-formed.
In the meantime, focus on the outer layer, and focus on just ONE element
at a time, to avoid confusing yourself.
I do this all the time, especially when I'm dealing with somebody else's
structured data, and I don't really know what they've done.
