重定向发生在处理表单数据之前
我在这里想做的是向销售人员发送一封电子邮件，通知他们他们的客户已查看 Google 文档演示文稿。
查询的 Num=val 是一个序列号，我用它从数据库中获取实际的 google 文档 url 并将其填充到表单中。
我的问题是，页面在检索数据之前重定向，并最终转到站点的默认值，硝基填充.com.index
gdform.php 文件具有标头重定向，如果我不尝试处理，该文件可以正常工作页面加载时的表单。代码如下：
<?php
$sn=$_GET['num'];
echo $sn;
mysql_connect($hostname,$username, $password) OR DIE ('Unable to connect to database! Please try again later.');
mysql_select_db($dbname);
$selectSQL = "select * from `Presentations` where `serialnum` ='" . $sn ."'" ;
$result = mysql_query($selectSQL) or die(mysql_error());
$row = mysql_fetch_array($result, MYSQL_BOTH);
?>
<script type="text/javascript">
function myfunc () {
var frm = document.getElementById("notice");
frm.submit();
}
window.onload = myfunc;
</script>
<title>Nitrofill Document</title></head>
<body>
<form id="notice" action="http://m3sglobal.com/gdform.php" method="post">
<input type="hidden" name="subject" value="<?php echo (urldecode($row['recipient'])) . " has viewed the document you sent them."; ?>" />
<input type="hidden" name="redirect" value="<?php echo ((urldecode($row['docurl']))); ?>"/>
<label>Email:</label><input type="text" name="email" value="<?php echo (urldecode($row['tracker'])); ?>"/>
<label>Comments:</label><textarea name="comments" cols="40" rows="5">
Document Viewed:<?php echo ((urldecode($row['docurl']))); ?>
When Accessed:<?php echo ((urldecode($row['last_accessed']))); ?>
</textarea>
<input type="submit" name="submit"/>
</form>
gdform.php 执行如下重定向：
while (list ($key, $val) = each ($query_vars)) {
fputs($fp,"<GDFORM_VARIABLE NAME=$key START>\n");
fputs($fp,"$val\n");
fputs($fp,"<GDFORM_VARIABLE NAME=$key END>\n");
if ($key == "redirect") { $landing_page = $val;}
}
fclose($fp);
if ($landing_page != ""){
header("Location: " . $landing_page);
} else {
header("Location: http://".$_SERVER["HTTP_HOST"]."/");
}
感谢您的查看！
What i'm trying to do here is to sends an email to a salesperson notifying them that their client has viewed a google docs presentation.
The query's Num=val is a serial number that I use to get the actual google doc's url out of a database and stuff it into a form.
My problem is that the page redirects before the data is retrieved, and ends up going to the default for the site, nitrofill.com.index
The gdform.php file has the header redirect, which works fine if I don't try to process the form when the page loads. Heres the code:
<?php
$sn=$_GET['num'];
echo $sn;
mysql_connect($hostname,$username, $password) OR DIE ('Unable to connect to database! Please try again later.');
mysql_select_db($dbname);
$selectSQL = "select * from `Presentations` where `serialnum` ='" . $sn ."'" ;
$result = mysql_query($selectSQL) or die(mysql_error());
$row = mysql_fetch_array($result, MYSQL_BOTH);
?>
<script type="text/javascript">
function myfunc () {
var frm = document.getElementById("notice");
frm.submit();
}
window.onload = myfunc;
</script>
<title>Nitrofill Document</title></head>
<body>
<form id="notice" action="http://m3sglobal.com/gdform.php" method="post">
<input type="hidden" name="subject" value="<?php echo (urldecode($row['recipient'])) . " has viewed the document you sent them."; ?>" />
<input type="hidden" name="redirect" value="<?php echo ((urldecode($row['docurl']))); ?>"/>
<label>Email:</label><input type="text" name="email" value="<?php echo (urldecode($row['tracker'])); ?>"/>
<label>Comments:</label><textarea name="comments" cols="40" rows="5">
Document Viewed:<?php echo ((urldecode($row['docurl']))); ?>
When Accessed:<?php echo ((urldecode($row['last_accessed']))); ?>
</textarea>
<input type="submit" name="submit"/>
</form>
The gdform.php does the redirect like this:
while (list ($key, $val) = each ($query_vars)) {
fputs($fp,"<GDFORM_VARIABLE NAME=$key START>\n");
fputs($fp,"$val\n");
fputs($fp,"<GDFORM_VARIABLE NAME=$key END>\n");
if ($key == "redirect") { $landing_page = $val;}
}
fclose($fp);
if ($landing_page != ""){
header("Location: " . $landing_page);
} else {
header("Location: http://".$_SERVER["HTTP_HOST"]."/");
}
Thanks for looking!

HTML 中的代码是自上而下执行的。一旦到达该 JavaScript 块，您就可以提交，甚至在您在页面上呈现表单之前。
将 JS 代码移至页面底部，或在 DOM 准备好后执行。
Code in HTML is executed top-down. You're submitting as soon as you get to that block of JavaScript, which is before you even render the form on the page.
Move your JS code to the bottom of the page, or execute it after the DOM is ready.
