Hello again!
I'm trying to find a good way to convert array key/value's to
variable name values... but with the caveat of the name being
slightly different than the original key
(to fit my naming conventions).
first, I (tediously) did this:
-------
if (isset($_GET['f_action'])) {
$t_action = $_GET['f_action'];
}
if (isset($_POST['f_action'])) {
$t_action = $_POST['f_action'];
}
if (isset($_GET['f_ap'])) {
$t_ap = $_GET['f_ap'];
}
if (isset($_POST['f_ap'])) {
$t_ap = $_POST['f_ap'];
}
-------
Instead, I wanted to find *all* incoming "f_" keys in the POST/GET array, and convert them to a variable name consisting of "t_" in one statement.
I then did this test and it appears to work (sorry for email line breaks):
---------
$a_formvars = array('f_1' => '1','f_2' => '2','f_3' => '3','f_4' => '4','f_5' => '5','f_6' => '6',);
$t_string = "";
foreach ($a_formvars as $key => $value) {
if (substr($key,0,2) == 'f_') {
$t_string = $t_string . "t_" . substr($key,2) . "=$value&";
parse_str($t_string);
}
}
---------
I figure I can adapt the above by doing something like:
$a_formvars = array_merge($_POST,$_GET);
However, I thought I'd check with you all to see if there is something
I'm missing. I don't speak PHP that well and there may be an easier way.
Thanks,
Donovan
