我需要一些帮助，我正在尝试使用 PDO 插入多个表 - 有人可以看到我做错了什么 - 我没有收到解析错误(也没有设置 Assets 错误):
这是我的表格:
addcontact.php
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Add New Contact</title>
<link rel="stylesheet" href="css/table.css" type="text/css" />
</head>
<body>
<div class="CSS_Table_Example" style="width:500px;height:350px;">
<center>
<form action="insert.php" method="post">
<p>
<td>
<tr><label for="ContactName">Contact Name:</label>
<input type="text" name="ContactName" id="ContactName">
</tr></p>
<p>
<tr> <label for="ContactTypeId">Contact Type:</label>
<select name="ContactTypeId">
<option value="1">Contact</option>
<option value="2">Organization</option>
</select>
</p>
<p>
<td>
<tr> <label for="AddressTypeId">Address Type:</label>
<select name="AddressTypeId">
<option value="1">Home</option>
<option value="2">Office</option>
<option value="3">Other</option>
</select>
</p>
<p>
<tr><label for="Address1">Address 1:</label>
<input type="text" name="Address1" id="Address1">

<p>

<input type="text" name="Address2" id="Address1">

<p>

这里是insert.php
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "crm";
//making an array with the data received, to use as named placeholders for INSERT by PDO.
$data = array('ContactName' => $_POST['ContactName'] , 'ContactTypeId'
=> $_POST['ContactTypeId'],
'ContactId'=> $_POST['ContactId'],'AddressTypeId'=>
$_POST['AddressTypeId'],'Address1'=>$_POST['Address1'],
'Address2'=>$_POST['
Address2'],'City'=>$_POST['City'],'StateId'=>$_POST['StateId']);
try {
// preparing database handle $dbh
$dbh = new PDO("mysql:host=$servername;dbname=$dbname",
$username,$password);
// set the PDO error mode to exception
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$currentID = mysql_inserted_id();
// query with named placeholders to avoid sql injections
$query = "INSERT INTO Contacts (ContactName, ContactTypeId)
VALUES(:ContactName, :ContactTypeId )";
$query2= "INSERT INTO
Addresses(ContactId,AddressTypeId,Address1,Address2,City,StateId)
VALUES(:$currentID,:AddressTypeId,:Address1,:Address2,:City,:StateId)";
//statement handle $sth
$sth = $dbh->prepare($query);
$sth->execute($data);
echo "New record created successfully";
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
$dbh = null;
?>
最佳答案
您需要为$query创建两个数组$data和为$query1创建$data1并且需要使用 $dbh->lastInsertId() 作为最后一个 id。使用下面的代码。我认为它会起作用:
<?php
$servername = "localhost";
$username = "root";
$password = "root";
$dbname = "crm";
//making an array with the data received, to use as named placeholders for INSERT by PDO.
$data = array('ContactName' => $_POST['ContactName'] , 'ContactTypeId'
=> $_POST['ContactTypeId']);
$data1=array('AddressTypeId'=>$_POST['AddressTypeId'],'Address1'=>$_POST['Address1'],
'Address2'=>$_POST['
Address2'],'City'=>$_POST['City'],'StateId'=>$_POST['StateId']);
try {
// preparing database handle $dbh
$dbh = new PDO("mysql:host=$servername;dbname=$dbname",
$username,$password);
// set the PDO error mode to exception
$dbh->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
// query with named placeholders to avoid sql injections
$query = "INSERT INTO Contacts (ContactName, ContactTypeId)
VALUES(:ContactName, :ContactTypeId )";
$sth = $dbh->prepare($query);
$sth->execute($data);
$currentID = $dbh->lastInsertId();
$query2= "INSERT INTO
Addresses(ContactId,AddressTypeId,Address1,Address2,City,StateId)
VALUES($currentID,:AddressTypeId,:Address1,:Address2,:City,:StateId)";
$sth = $dbh->prepare($query2);
$sth->execute($data1);
//statement handle $sth
echo "New record created successfully";
}
catch(PDOException $e)
{
echo $sql . "<br>" . $e->getMessage();
}
$dbh = null;
?>
