Thanks for the code. I got it working with a couple of changes.
But then I realized that with the new table design I can't anymore
easily sort by a given year (1970 or 2000). This is surely one of
the advantages of the "old" design, that the use via PHP was quite
straight forward.
Do I have to transfer the query results into a PHP array to sort
it in there, then?
Umm - not sure what you're after. What's wrong with one of:
SELECT ... ORDER BY year, value
SELECT ... ORDER BY value, year
Or did you want a particular year pulled out of the general list,
in which case try something like:
SELECT ... ORDER BY (year = 1970), year, value
SELECT ... ORDER BY (year <> 1970), year, value
This works because booleans are considered sortable too.
Wow, didn't know about the "(year = 1970)" thing. Cool. But
nevertheless, the problem is then with the PHP code above; a
different sorting in the query result, means as well a different
coding. Or I have completely miscoded your draft. But I don't see how
it would handle a resulting array of any order - by year, by name,
ascending, descending... I guess I need to go with the PHP array, no?
$current_country = -1;
$count = -1;
$cols = array();
while ($row = pg_fetch_array($result))
{
if ($row['name'] != $current_country)
{
if (sizeof($cols) > 0)
{
$count++;
$code7 .= display_table_row($current_country, $cols, $count,
$selectedDataset -> name, $selectedID, $selectedTime);
}
$cols = array();
$current_country = $row['name'];
}
$cols[] = $row['value'];
}
// handle possible last row of table
if (sizeof($cols) > 0)
{
$code7 .= display_table_row($current_country, $cols, ($count + 1),
$selectedDataset -> name, $selectedID, $selectedTime);
}
