我需要将数组插入数据库。我的形式看起来像
<form action="" method="post">
<p>servicename</p>
<input type="text" name="service_name"><br>
<p>bgname</p>
<input type='text' name="background[]">
<input type='text' name="background[]">
<input type='text' name="background[]">
<p>bg price:</p>
<input type='text' name="background_price[]">
<input type='text' name="background_price[]">
<input type='text' name="background_price[]">
<p>resolution:</p>
<input type='text' name="resolution[]">
<input type='text' name="resolution[]">
<p>resolution price</p>
<input type='text' name="resolution_price[]">
<input type='text' name="resolution_price[]">
<p>count</p>
<input type='text' name="count[]">
<input type='text' name="count[]">
<input type='text' name="count[]">
<input type='text' name="count[]">
<input type='text' name="count[]">
<p>count price</p>
<input type='text' name="count_price[]">
<input type='text' name="count_price[]">
<input type='text' name="count_price[]">
<input type='text' name="count_price[]">
<input type='text' name="count_price[]">
<p>Type:</p>
<input type='text' name="type[]">
<input type='text' name="type[]">
<input type='text' name="type[]">
<p>Type price</p>
<input type='text' name="type_price[]">
<input type='text' name="type_price[]">
<input type='text' name="type_price[]">
<p>how</p>
<input type='text' name="how[]">
<input type='text' name="how[]">
<p>how price</p>
<input type='text' name="how_price[]">
<input type='text' name="how_price[]">
<input type="submit" name="submit">
</form>
我也编写了可行的脚本，但是我有太多不必要的表，我想将它优化到一个表
<?php
class Service extends Connection {
public function addService($service_name, $background, $background_price, $resolution, $resolution_price, $count, $count_price, $type, $type_price, $how, $how_price) {
try {
$sth = $this->dbh->prepare("INSERT IGNORE INTO services (id, name) VALUES ('', ?)");
$sth->bindParam(1, $service_name, PDO::PARAM_STR);
$sth->execute();
} catch (PDOException $e) {
echo $e->getMessage();
}
foreach($background as $index1 => $backgroundItem) {
try {
$sth = $this->dbh->prepare("INSERT IGNORE INTO background (id, service_name, background, background_price) VALUES ('', ?, ?, ?)");
$sth->bindParam(1, $service_name, PDO::PARAM_STR);
$sth->bindParam(2, $backgroundItem, PDO::PARAM_STR);
$sth->bindParam(3, $background_price[$index1], PDO::PARAM_INT);
$sth->execute();
} catch (PDOException $e) {
echo $e->getMessage;
}
}
foreach($resolution as $index2=> $resolutionItem) {
try {
$sth = $this->dbh->prepare("INSERT IGNORE INTO resolution (id, service_name, resolution, resolution_price) VALUES ('', ?, ?, ?)");
$sth->bindParam(1, $service_name, PDO::PARAM_STR);
$sth->bindParam(2, $resolutionItem, PDO::PARAM_STR);
$sth->bindParam(3, $resolution_price[$index2], PDO::PARAM_INT);
$sth->execute();
} catch (PDOException $e) {
echo $e->getMessage();
}
}
foreach($count as $index3=> $countItem) {
try {
$sth = $this->dbh->prepare("INSERT IGNORE INTO counts (id, service_name, count, count_price) VALUES ('', ?, ?, ?)");
$sth->bindParam(1, $service_name, PDO::PARAM_STR);
$sth->bindParam(2, $countItem, PDO::PARAM_STR);
$sth->bindParam(3, $count_price[$index3], PDO::PARAM_INT);
$sth->execute();

echo $e->getMessage();
}
}
foreach($type as $index4=> $typeItem) {
try {
$sth = $this->dbh->prepare("INSERT IGNORE INTO type (id, service_name, type, type_price) VALUES ('', ?, ?, ?)");
$sth->bindParam(1, $service_name, PDO::PARAM_STR);

如何将数组保存到表格＆＃39;服务＆＃39;看起来像是
id | service_name | background | background_price | count | count_price | type | type_price | how | how_price | resolution | resolution_price
我从Stack尝试了很多解决方案，但没有什么能帮助我.Regards exported schema table 'services'
答案 0 :(得分：0)
如果我理解你的问题以及你想要达到的目标，那么这就是解决问题的方法之一：
class Service extends Connection {
public function addService($service_name, $background, $background_price, $resolution, $resolution_price, $count, $count_price, $type, $type_price, $how, $how_price) {
$max = max(count($background), count($background_price), count($resolution), count($resolution_price), count($count), count($count_price), count($type), count($type_price), count($how), count($how_price));
try {
$query = "INSERT INTO services (`service_name`, `background`, `background_price`, `count`, `count_price`, `type`, `type_price`, `how`, `how_price`, `resolution`, `resolution_price`) VALUES ";
$data = [];
for ($i = 0; $i < $max; $i++) {
$query .= "(?,?,?,?,?,?,?,?,?,?,?),";
$data[] = isset($service_name) ? $service_name : '';
$data[] = isset($background[$i]) ? $background[$i] : '';
$data[] = isset($background_price[$i]) ? $background_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($count[$i]) ? $count[$i] : '';
$data[] = isset($count_price[$i]) ? $count_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($type[$i]) ? $type[$i] : '';
$data[] = isset($type_price[$i]) ? $type_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($how[$i]) ? $how[$i] : '';
$data[] = isset($how_price[$i]) ? $how_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($resolution[$i]) ? $resolution[$i] : '';
$data[] = isset($resolution_price[$i]) ? $resolution_price[$i] : 0; // OR '' depending on the column type
}
$query = rtrim($query, ',');
$sth = $this->dbh->prepare($query);
$sth->execute($data);
} catch (PDOException $e) {
echo $e->getMessage();
}
}
}
这是对每个插入进行单一查询的第二种方法：
class Service extends Connection {
public function addService($service_name, $background, $background_price, $resolution, $resolution_price, $count, $count_price, $type, $type_price, $how, $how_price) {
$max = max(count($background), count($background_price), count($resolution), count($resolution_price), count($count), count($count_price), count($type), count($type_price), count($how), count($how_price));
try {
$query = "INSERT INTO services (`service_name`, `background`, `background_price`, `count`, `count_price`, `type`, `type_price`, `how`, `how_price`, `resolution`, `resolution_price`) VALUES (?,?,?,?,?,?,?,?,?,?,?)";
for ($i = 0; $i < $max; $i++) {
$data = [];
$data[] = isset($service_name) ? $service_name : '';
$data[] = isset($background[$i]) ? $background[$i] : '';
$data[] = isset($background_price[$i]) ? $background_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($count[$i]) ? $count[$i] : '';
$data[] = isset($count_price[$i]) ? $count_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($type[$i]) ? $type[$i] : '';
$data[] = isset($type_price[$i]) ? $type_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($how[$i]) ? $how[$i] : '';
$data[] = isset($how_price[$i]) ? $how_price[$i] : 0; // OR '' depending on the column type
$data[] = isset($resolution[$i]) ? $resolution[$i] : '';
$data[] = isset($resolution_price[$i]) ? $resolution_price[$i] : 0; // OR '' depending on the column type
$sth = $this->dbh->prepare($query);
$sth->execute($data);
}
} catch (PDOException $e) {
echo $e->getMessage();
}
}
}
当找到重复行时，UPDATE代替INSERT：
class Service extends Connection {
public function addService($service_name, $background, $background_price, $resolution, $resolution_price, $count, $count_price, $type, $type_price, $how, $how_price) {
$max = max(count($background), count($background_price), count($resolution), count($resolution_price), count($count), count($count_price), count($type), count($type_price), count($how), count($how_price));
try {
$query = "INSERT INTO services (`service_name`, `background`, `background_price`, `count`, `count_price`, `type`, `type_price`, `how`, `how_price`, `resolution`, `resolution_price`) VALUES
(:service_name, :background,:background_price,:count,:count_price,:type,:type_price,:how,:how_price,:resolution,:resolution_price)
ON DUPLICATE KEY UPDATE
`background`=:background2, `background_price`=:background_price2, `count`=:count2, `count_price`=:count_price2,
`type`=:type2, `type_price`=:type_price2, `how`=:how2, `how_price`=:how_price2, `resolution`=:resolution2, `resolution_price`=:resolution_price2";
for ($i = 0; $i < $max; $i++) {
$data = [];
$data[':service_name'] = isset($service_name) ? $service_name : '';
$data[':background'] = isset($background[$i]) ? $background[$i] : '';
$data[':background2'] = isset($background[$i]) ? $background[$i] : '';
$data[':background_price'] = isset($background_price[$i]) ? $background_price[$i] : 0; // OR '' depending on the column type
$data[':background_price2'] = isset($background_price[$i]) ? $background_price[$i] : 0; // OR '' depending on the column type
$data[':count'] = isset($count[$i]) ? $count[$i] : '';
$data[':count2'] = isset($count[$i]) ? $count[$i] : '';
$data[':count_price'] = isset($count_price[$i]) ? $count_price[$i] : 0; // OR '' depending on the column type
$data[':count_price2'] = isset($count_price[$i]) ? $count_price[$i] : 0; // OR '' depending on the column type
$data[':type'] = isset($type[$i]) ? $type[$i] : '';
$data[':type2'] = isset($type[$i]) ? $type[$i] : '';
$data[':type_price'] = isset($type_price[$i]) ? $type_price[$i] : 0; // OR '' depending on the column type
$data[':type_price2'] = isset($type_price[$i]) ? $type_price[$i] : 0; // OR '' depending on the column type
$data[':how'] = isset($how[$i]) ? $how[$i] : '';
$data[':how2'] = isset($how[$i]) ? $how[$i] : '';
$data[':how_price'] = isset($how_price[$i]) ? $how_price[$i] : 0; // OR '' depending on the column type
$data[':how_price2'] = isset($how_price[$i]) ? $how_price[$i] : 0; // OR '' depending on the column type
$data[':resolution'] = isset($resolution[$i]) ? $resolution[$i] : '';
$data[':resolution2'] = isset($resolution[$i]) ? $resolution[$i] : '';
$data[':resolution_price'] = isset($resolution_price[$i]) ? $resolution_price[$i] : 0; // OR '' depending on the column type
$data[':resolution_price2'] = isset($resolution_price[$i]) ? $resolution_price[$i] : 0; // OR '' depending on the column type
$sth = $this->dbh->prepare($query);
$sth->execute($data);
}
} catch (PDOException $e) {
echo $e->getMessage();
