我正在从事一个涉及从两个不同服务器获取信息的项目。我打算做的是让用户输入他或她的用户名密码,然后用php脚本填写名字姓等下面的其余字段。我进行了一些搜索,发现我拥有的一些数据在服务器中的两个不同表。下面是我到目前为止的编码。
<?php
$connect = mysql_connect("localhost","**************","**********") or die ("Couldn't Connect"); //host,username,password
mysql_select_db("*******") or die ("Could not find database");
$query = mysql_query("SELECT * FROM jos_users WHERE username='$username'");
?>
<html>
<form action="populate.php" method='post'>
<table>
<tr>
<td>VAE Username:</td>
<td><input type='text' name='username' value=''></td>
</tr>
<tr>
<td>VAE Password:</td>
<td><input type='password' name='password' value=''></td>
</tr>
</table>
<p><input type='submit' name='submit' value='Search & Populate!'></p>
</form>
//below is the information i want filled in from the MYSQL tables
<hr>
$query = mysql_query("SELECT * FROM jos_users WHERE username='$username'");
<form action="dafreg.php" method='post'>
<table>
<tr>
<td>Fristname:</td>
<td><input type='text' name='firstname' value='<?php echo $firstname; ?>'></td>
</tr>
<tr><td>Lastname:</td>
<td><input type='text' name='lastname' value='<?php echo $lastname; ?>'></td>
</tr>
<tr>
<td>Login:</td>
<td><input type='text' name='login' value='<?php echo $username; ?>'></td>
</tr>
<tr><td>Password:</td>
<td><input type='text' name='pass' value=''></td>
</tr>
<tr><td>Country:</td>
<td><input type='text' name='country' value=''></td>
</tr>
<tr><td>Pilot:</td>
<td><input type='checkbox' name='pilot' value=''></td>
</tr>
<tr><td>ATC:</td>
<td><input type='checkbox' name='atc' value=''></td>
</tr>
<tr><td>Email:</td>
<td><input type='text' name='email' value=''></td>
</tr>
</table>
<p><input type='submit' name='submit' value='Register'></p>
</form>
</form>
</html>
最佳答案
使用'JOIN'将是提取数据多表的最佳选择...
SELECT tab1.*,tab2.*
FROM table1 tab1 JOIN table2 tab2
ON tab1.id=tab2.id
WHERE tab1.username=$username
