Description:
------------
This is maybe related/similar to bug #204
(http://pear.php.net/bugs/bug.php?id=204), however, the
proposed solution there didn't help.

I am using (the BTW superb) Flexy Template to generate a
HTML document from session data to implement a shopping
basket. Because of the nature of the circumstances, the
names of the form data have to be dynamically generated.

I am using PHP style configuration files to store the
attributes of form elements, eg.:
$conf = array(
'shipping' => array(
'attributes' => array(
'type' => 'text',
'size' => 8,
'maxlength' => 8,
'readonly' => 'readonly'
),
'setValue' => sprintf('%.2f', $this->country[0]
['Shipping'])
),
...
);
--eof
This data is processed and passed to the appropriate
HTML_Template_Flexy_Element method, which works perfectly
for statically named form elements.
For the dynamic named form elements I tried to add
elements like this:

// SQL query to get results into $this->summary
$i = 0;
foreach($this->summary as $key => $val) {
$conf["items$i"] = array(
'attributes' => array(
'type' => 'text',
),
'setValue' => $this->summary['items']
);
}
--eof

However, the results aren't as expected (as seen below).
Any way to work artound this and still keep the template
approach?

Reproduce code:
---------------
template:
{foreach:summary,key,row}
<input name="price{key}" butt="head">
<input name="items%s" flexy:nameuses="member.line" butt="head">
{end:}
--eof

Expected result:
----------------
<input name="price0" type="text" value="22.00">
<input name="items0" type="text" value="1">

<input name="price1" type="text" value="33.00">
<input name="items1" type="text" value="2">
...
--eof

Actual result:
--------------
<input name="price0" butt="head">
<input name="items" butt="head">

<input name="price1" butt="head">
<input name="items" butt="head">

Uhm, forgot the $i++; inside the foreach()...

Nope, it still doesn't work.
But the $i++ is obviously necessary in order for the
foreach loop to create a proper data structure, so I
posted it to prevent "you need a $i++ inside your foreach"
replies.
I double checked both the results of the SQL query and the
generated data, they are ok and not the problem here.

Ok, it does work now. I made a wrong use of the
undocumented flexy:nameuses="name" feature.
It does work in the original project except in one place,
so I guess I still have something wrong there.
THX for your help.
Bug closed, the call for better documentation can be
heard...
