我有下一个代码
$rez1 = mysqli_query($kon, "SELECT producten.*,producten.id as prodID, product_shop_tt.*, COUNT(order_details.id) AS order_count from producten
INNER JOIN product_shop_tt ON producten.id = product_shop_tt.product_id
LEFT JOIN order_details ON order_details.product_shop_tt_id = product_shop_tt.id
WHERE product_shop_tt.shop_id = '" . $red['id'] . "'
GROUP BY producten.id
ORDER BY order_count DESC");
$brRez = mysqli_num_rows($rez1);
$i = 1;
while($red1 = mysqli_fetch_assoc($rez1)){
$brProizvoda = $red1["order_count"];
if($brProizvoda >= 30){
$pozadina = "background-color:#C4C4B3;border-radius:10px";
}elseif(($brProizvoda < 30) && ($brProizvoda > 10)){
$pozadina = "background-color:#E0E0D8;border-radius:10px";
}else{
$pozadina = "background-color:#FFFFFF;border-radius:10px";
}

我现在想检查数组 txtHidd [“。$ red1 [”prodID“]中的每个 kolicina 值。”] [kolicina ] 是空的。
我正在尝试
$empty = array_filter($_POST["txtHidd"]);
if (empty($empty)) {
echo "Empty";
}
这样,如果所有值都为空,我会变空,但如果一个或多个值等于其他值,我也会为空。如果数组 txtHidd [“。$ red1 [”prodID“]。”] [kolicina] 中的所有 kolicina 值,则如何获取为空空?
答案 0 :(得分:2)
使用array_column()
创建所有当前kolicina
值的数组。然后使用array_filter()
过滤掉您认为&#34;空&#34;的所有值。如果这导致空数组,则所有$txtHidd[...]['kolicina']
都为空。
编辑:
好的,让我们说,你有这个阵列:
$_POST['txtHidd'] = array(
array('a' => 'b', 'c' => 'd', 'kolicina' => ''),
array('a' => 'f', 'c' => '1', 'kolicina' => 'abc'),
array('a' => 'x', 'c' => '6', 'kolicina' => NULL),
array('a' => 'o', 'c' => 'u', 'kolicina' => 'xxx')
);
您想知道,如果所有kolicina
值都为空,那么这样吗?所以你使用:
$kolicinas = array_column($_POST['txtHidd'], 'kolicina');
这会给你:
array('', 'abc', NULL, 'xxx')
现在您问,是否所有这些值都是空的。所以你这样做:
$non_empty_kolicinas = array_filter($kolicinas);
你得到:
array('abc', 'xxx')
这意味着,存在非空的kolicinas(无论是什么:-)。也许我误解了你的问题,在这种情况下纠正我,拜托!

使用此代码
if(isset($_POST["txtHidd"])){
echo "Not Empty";
}
