Hiya,
I have created a dynamic table within my form.
Above the table I want to insert a filter to order by:the column names
Here is the static list:
select name=select4
optionSeverity/option
optionCrash/option
optionMajor/option
optionMinor/option
optionReview/option
/select
What I need suggestions on is:
1. recommended tutorials on lists and logic behind them.
2. How does the selected item in the list get stored (a variable?)and how
can I place that in such a way to ORDER BY $filter_selected
3. also simple snippets of code always is appreciated (No one wants to
reinvent the wheel) :)
Checkbox, select, input text, textarea, who cares ... it
all comes out the same. Read this:

The real question is is your form POST or GET, you will
find the answer within the above manual page on how to
retrieve the value. Hint: $_POST['select4']; Now let's
say you want to make sure it's appropriate first, and
then create the query, here's an example:
$selects = array('severity','crash','major','minor','review');
$select = strtolower($_POST['select4']);
if (!in_array($select, $selects)) {
$select = 'severity';
}
$sql = SELECT a FROM b ORDER BY $select LIMIT 40:
Of course that assumes those are table names in your db. You
may want to be a little more user friendly and do for example:
option value='severity'The Severity blah blah/option
