// NEW 11/27/2006: FINALLY, IF YOU ADDED OR DELETED OR DID ANY KIND OF
FORM ACTION SUCCESSFULLY, DON'T RE-DISPLAY THE NEW EXPENSE ITEMS VIA
$_POST
if ($_POST['hasUpdatedLease'] && (!is_array($leaseObj->errorArray) ||
@sizeof($leaseObj->errorArray) == 0)) {
print_r(array_keys($_POST));
@reset($_POST);
$tempPost = $_POST;

print_r(array_keys($_POST));
}
[/PHP]
For some reason, even though the condition is always met when I click
any of the form submit images, the following "weird behavior patterns"
occur:
1) If I click the "Add" submit image, all $_POST values whose keys
start with "new_" should be removed from $_POST. However,
$_POST['new_audited'] and $_POST['new_reoccuring'] remain
2) If I click the "Delete" submit image, all $_POST values whose keys
start with "new_" should be removed from $_POST. However, *ALL* of
them remain in $_POST untouched!
I can verify that I enter the conditional block by my arrays appearing
on screen every time.
Any reason why this is happening that I missed?
Thanx

Never heard of array_remove, I wonder what it does. Could it be it's not
actually removing anything? Why not just:
unset($tempPost[$key]);

Still, why not just unset the element right away. Now you're risking of
removing the wrong element when you remove something by the value, not key.
Imagine a case like this:
$foo = array('0','0','0','0','0');
If you tell me to remove the element that has the value '0', how am I gonna
know which element it is, if there are five zeros? Instead, if you tell me
to remove the fourth element, I have no trouble telling which element you
mean. I think the real problem here is actually that wrong elements are
removed from the array. because they ahve the same value. It says in the
manual: "If $needle is found in $haystack more than once, the first matching
key is returned."
Just try this code and see what happens:
$foo = array('0','0','0','0','0');
print_r($foo);
array_remove($foo, $foo[4]);
print_r($foo); // Was the fourth element removed? I think not.
And then try this:
$foo = array('0','0','0','0','0');
print_r($foo);
unset($foo[4]);
print_r($foo); // *Now* was the fourth element removed?

If you tell me to remove the element that has the value '0', how am I gonna

$foo = array('0','0','0','0','0');
print_r($foo);
unset($foo[4]);
print_r($foo); // *Now* was the fourth element removed?
FIXED!
Got it, apparently my own blunder; I was using the wrong user-defined
function: instead of array_remove(), I needed
array_remove_element_at():
if (!function_exists('array_remove_element_at')) { // FUTURISTIC: MODEL
AFTER JAVA Vector.removeElementAt(index)
/**
* Function modeled after {@link http://java.sun.com/j2se/1.4.2/docs/...eElementAt(int)

* @return mixed $element
*/
function array_remove_element_at(&$array, $key = '') {
if (is_numeric($key) || (!is_numeric($key) && $array[$key])) {
if (is_numeric($key)) {
$element = $array[$key];
unset($array[$key]);
$array = @array_values($array); // RE-ORDER ENUMERATIVE ARRAY
} elseif (!is_numeric($key) && $array[$key]) {
$element = $array[$key];
unset($array[$key]);
}
}
return $element;
}
}
$tempPost = $_POST;
foreach ($_POST as $key =$val) if (strpos(trim($key), 'new_') ===0)
@array_remove_element_at($tempPost, $key);
$_POST =& $tempPost;
Also obviously don't need to use reset() either since the array pointer
is irrelevant in this case, at least I think so..
