我在使用pdo準備語句在mysql中插入多行時出現了一些問題。
該插入工作,但只有一次。
我試圖把foreach之前的查詢,但同樣的問題。
$product_id = $_POST['id'];
if (isset($_POST['product_attribute'])){
$att_id = array();
foreach ($_POST['product_attribute'] as $product_attribute) {
$att_id[] = $product_attribute['attribute_id'];
if ($product_attribute['attribute_id']) {
$stmt = $database->prepare("DELETE FROM product_attribute WHERE product_id =:product_id AND attribute_id=:attribute_id");
$stmt->bindParam(':product_id', $product_id, PDO::PARAM_INT);
$stmt->bindParam(':attribute_id', $product_attribute['attribute_id'], PDO::PARAM_INT);
$stmt->execute();
foreach ($product_attribute['product_attribute_description'] as $product_attribute_description) {
$stmt = $database->prepare("INSERT INTO product_attribute SET product_id=:product_id, product_code=:product_code, attribute_id=:attribute_id, `text`=:atext");
$stmt->bindParam(':product_id', $product_id, PDO::PARAM_INT);
$stmt->bindParam(':product_code', $_POST['codprodus'], PDO::PARAM_INT);
$stmt->bindParam(':attribute_id', $product_attribute['attribute_id'], PDO::PARAM_INT);
$stmt->bindParam(':atext', $product_attribute_description['text'], PDO::PARAM_STR);
$stmt->execute();
}
}
}
$vals = implode(",", $att_id);
$stmt = $database->prepare("DELETE FROM product_attribute WHERE product_id =:product_id AND attribute_id NOT IN(:vals)");
$stmt->bindParam(':product_id', $product_id, PDO::PARAM_INT);
$stmt->bindParam(':vals', $vals, PDO::PARAM_STR);
$stmt->execute();
}else {
$stmt = $database->prepare("DELETE FROM product_attribute WHERE product_id =:product_id");
$stmt->bindParam(':product_id', $product_id, PDO::PARAM_INT);
$stmt->execute();
}
的print_r($ _ POST [ 'product_attribute']:
Array([103] => Array(
[attribute_id] => 103
[product_attribute_description] => Array
(
[2] => Array
(
[text] => 56
)
)
)
[102] => Array
(
[attribute_id] => 102
[product_attribute_description] => Array
(
[2] => Array
(
[text] => da
)
)
)
[104] => Array
(
[attribute_id] => 104
[product_attribute_description] => Array
(
[2] => Array
(
[text] => da
)
)
)
)
這裏是我的product_attribute表模式
product_id int(11) NO PRI
attribute_id int(11) NO PRI
product_code int(11) NO
text text NO
試試看從'$ product_attribute_description ['text']''移動'['text']''因爲您正在做'product_attribute_description' – 2015-03-03 14:19:10
如果我刪除它,結果將會是數組 – speedy 2015-03-03 14:21:17
您是否嘗試過'implode()'? – 2015-03-03 14:21:57
