mysql_num_rows（）：提供的参数不是一个有效的MySQL结果资源警告

Question

的问题如下：

Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /home/a2138233/public_html/etc/e.conf/sys.proc/proc.reg/use.register.php on line 113 

这里的use.register.php 113 线：

$sql_email_check = mysql_query("SELECT uMail FROM eusers WHERE uMail='$rmail' "); 
$email_check = mysql_num_rows($sql_email_check); 

这里的变量设置为“$ rmail”：

$rmail  = mysql_real_escape_string(strip_tags($_POST['rmail'])); 

下面是HTML行：

<input type="text" class="umail" id="ftxti" name="rmail" placeholder='email@server.com' style="width: 530px;" > 

全码：

<?php 
$mysql_host = ""; 
$mysql_database = ""; 
$mysql_user = ""; 
$mysql_password = ""; 

$link = mysql_connect($mysql_host, $mysql_user, $mysql_password, $mysql_database); 
mysql_select_db("tmpu"); 

?> 

<?php

你需要一个值属性附加伤害在你输入

<input type="text" class="umail" id="ftxti" name="rmail" value="" placeholder='email@server.com' style="width: 530px;" > 

，我不知道你在你的代码有一个表单标签？ 。

<form name="yourform" method="POST" action ="" > 

    ......... 
    your html inputs here 

</form>
