Re: [PHP-DB] checking for empty array from a form field? grrrrrrrrrrr!
First try isset($product) to see if it's being POSTed or GETted
properly. You might need to use $_POST['products'] or
$_GET['products'].

What about:
count($arrayname)
Should tell you how many items are in an array.

I usually use:
while(list($key,$value) = each($products)) {
echo $key:$value;
}

RE: [PHP-DB] checking for empty array from a form field? grrrrrrrrrrr!
Ok... well
When I select the select product which has a option value= it tells
me the count is one (1). If I select an ACTUAL product it tells me
one(1) was select.. if I select two ACTUAL products it tells me two (2)
products were selected.
For SOME reason it doesn't seem to be recognizing that the option
value= is empty!
Any more ideas??
*sigh*

to find out if an array is empty use:
empty()
it must be unset
NULL returns false
0 returns false
it must be truly empty to return true...
Ok... well
When I select the select product which has a option value= it tells
me the count is one (1). If I select an ACTUAL product it tells me
one(1) was select.. if I select two ACTUAL products it tells me two (2)
products were selected.

Somebody else replied with isset($varname). Try that. The count() function
is working as expected (see
http://www.php.net/manual/en/function.count.php). So maybe it's not the best
choice for trying to find out what you want.

RE: [PHP-DB] checking for empty array from a form field? grrrrrrrrrrr!
Well well well.. with the help of someone else pointing me in a
different direction altogether here's what we came up with that totally
works!
$PRODUCT_SELECTED = TRUE;
foreach($products as $value) {
if(empty($value)) {
$PRODUCT_SELECTED = FALSE;
}
last;
}
if(!$PRODUCT_SELECTED) {
$productQuery = db_query(SELECT name FROM CartTable
WHERE submitted=1 GROUP BY name);
while ($productResult = db_fetch($productQuery)) {
$products[] = $productResult[name];
}
$prod_search = in(;
for ($i=0;$icount($products);$i++) {
$prod_search .=
escapeQuote($products[$i]);
if ($i !=
(count($products) - 1)) {
$prod_search .=
,;
}
}
$prod_search .= );
$product = AND name $prod_search;
}
else {
$prod_search = in(;
for ($i=0;$icount($products);$i++) {
$prod_search .= escapeQuote($products[$i]);
if ($i != (count($products) - 1)) {
$prod_search .= ,;
}
}
$prod_search .= );
$product = AND name $prod_search;
}
Thanks to all for their support and help on this. Longest 4 hours of my
life :(
