用textarea使用$ _POST问题 [英] Issue using $_POST with a textarea
问题描述
我在网站上有一个简单的联系表单，其中包含2个文本字段，1个textarea和1个隐藏字段。
由于某些原因，一个除textarea之外的PHP脚本。我以前做过这一千次，从未有过这个问题。
这是我的HTML：
< form action = scripts / contactform.phpmethod =post>
< tr>
< td>名称：< / td>
< td>< input name =nametype =textmaxlength =50/>< / td>
< / tr>
< tr>
< td>电子邮件：< / td>
< td>< input name =emailtype =text/>< / td>
< / tr>
< tr>
< td>讯息：< / td>
< td>< textarea name =commentid =commentcols =30rows =5>< / textarea>
< input type =hiddenvalue =<？php echo $ _SERVER ['REMOTE_ADDR'];？> name =address/>
< / td>
< / tr>
< tr>
< td colspan =2align =center>< input name =submittype =submitvalue =Submitclass =noroundid =regbut/> < input name =resettype =resetvalue =Resetclass =noroundid =regbut/>< / td>
< / tr>
< / table>
< / form>
我的脚本如下所示：
$ link = mysql_connect（DB_HOST，DB_USER，DB_PASSWORD）;
if（！$ link）
{
die（'无法连接到服务器：'。mysql_error（））;
}
$ db = mysql_select_db（DB_DATABASE）;
if（！$ db）
{
die（无法选择数据库）;
}
$ name = mysql_real_escape_string（$ _ POST ['name']）;
$ email = mysql_real_escape_string（$ _ POST ['email']）;
$ comment = mysql_real_escape_string（$ _ POST ['comment']）;
$ ipaddress = mysql_real_escape_string（$ _ POST ['address']）;
我有几件事要处理下面的数据，但这并不重要，因为 $ comment 变量未被定义。我搜索了整个脚本，并且没有相互冲突的变量名称。
我完全害怕这种情况发生的原因。我之前多次在我的网站上成功处理过 textarea 的所有内容，所以这确实令人困惑。
我曾经遇到类似于你的错误。帮助我的是使用不同的 id 和 name 参数。亲自尝试一下，因为在这里你有他们相同的。
I have a simple contact form on a website that has 2 text fields, 1 textarea, and 1 hidden field.
For some reason, all the fields POST to a PHP script except the textarea. I have done this a thousand times before and never had this issue.
Here is my HTML:
<form action="scripts/contactform.php" method="post">
<table width="0" border="0" cellspacing="3" cellpadding="5" class="gpass">
<tr>
<td>Name:</td>
<td><input name="name" type="text" maxlength="50" /></td>
</tr>
<tr>
<td>E-mail:</td>
<td><input name="email" type="text"/></td>
</tr>
<tr>
<td>Message:</td>
<td><textarea name="comment" id="comment" cols="30" rows="5"></textarea>
<input type="hidden" value=" <?php echo $_SERVER['REMOTE_ADDR'];?>" name="address" />
</td>
</tr>
<tr>
<td colspan="2" align="center"><input name="submit" type="submit" value="Submit" class="noround" id="regbut" /><input name="reset" type="reset" value="Reset" class="noround" id="regbut"/></td>
</tr>
</table>
</form>
And my script looks like this:
$link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD);
if(!$link)
{
die('Failed to connect to server: ' . mysql_error());
}
$db = mysql_select_db(DB_DATABASE);
if(!$db)
{
die("Unable to select database");
}
$name = mysql_real_escape_string($_POST['name']);
$email = mysql_real_escape_string($_POST['email']);
$comment = mysql_real_escape_string($_POST['comment']);
$ipaddress = mysql_real_escape_string($_POST['address']);
I have a few things to process the data underneath this, but that doesn't matter since the $comment variable isn't being defined. I've searched the entire script and there are no conflicting variable names.
I am completely stumped on why this is happening. I've successfully processed textarea's on my site multiple times before, so this really is confusing.
I once experienced an error similar to yours. What helped me was to use different id and name parameters. Try and see for yourself, because you have them identical here.
