Question

我有一个php文件，其中有一个表单和2个提交按钮，单击1个按钮，它必须传递从下拉列表中选择的值。它没有将值传递给接受POST数据的php文件。但是，如果我只有一个按钮和相同的表单，这工作正常。 Pl在下面找到我的代码。

<html>
<head>
<title>Invoice Printing</title>

<script type="text/javascript">
function showlink() 
{
window.open('invoiceprint2.php');
} 

function showlink3() 
{
window.open('invoiceprint3.php');
}   

</script>

</head>
<body>
<table width="100%"  border="0" cellpadding="0" cellspacing="0" bgcolor="#026465">
  <tr>
    <td><div align="center"><span class="style1"> Amogh Gases Private Ltd <br></span>
<center class="style5">INVOICE PRINTING</center>
<br><br>
<br>

</td>
  </tr>
</table>

<!--------------VALIDATIONS ------------------->

<br>

<form name="form1" method="post" action="" target="_blank">
<table width='40%' height='39'  border='0' cellpadding='2' cellspacing='0'     align='center'>
<tr>
<td class='sty1'><div align='left'>Please select Invoice No. to PRINT: <br>
<br>
You can choose more than one invoice number from the options, by holding CTRL key on     your keyboard and select the numbers.</div></td>
<td>
<?php
    $con = mysql_connect("localhost","tech1","te!@#");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}
mysql_select_db("tech1", $con);

$result = mysql_query("SELECT Invno FROM INVHDR", $con);
echo "<select multiple='multiple' size='20' name='invnos[]'>";
while($nt=mysql_fetch_assoc($result))
{//Array or records stored in $nt
echo "<option value=$nt[Invno]>$nt[Invno]</option>";
/* Option values are added by looping through the array */
}
echo "</select>";// Closing of list box

mysql_close($con);
?>

</td>
</tr>
</table><br>


<center><input name="PRINT" type="button" value="PRINT Invoice to Laser Printer!"     onClick='showlink();' /> &nbsp;&nbsp;&nbsp;  <input name="PRINT2" type="button" value="PRINT Invoice to Dotmatrix Printer !" onClick='showlink3();'/>
