问题描述
我正在尝试创建一个用户和密码验证页面,我有3个页面
index.php
I am trying to make a User and Password validation page, i have 3 pages
index.php
<<pre lang="xml">form ONSUBMIT="return validacion(this)" action="validation.php" method="post" name="form">
<center>
<table border="0">
<tr>
<td>
User:
</td>
<td>
<input name="login" type="text" id="login" />
</td>
</tr>
<tr>
<td>
Password:
</td>
<td>
<input name="password" type="password" id="password" />
</td>
</tr>
<tr>
<td>
<input type="submit" value="Enviar" />
</td>
<td>
<input type="reset" value="Borrar" />
</td>
</tr>
</table>
</center>
</form
validation.php
validation.php
if ($_REQUEST[''login'']!="" and $_REQUEST[''password'']!="")
{
$table = "users";
require(''conect.php'');
$link=conect();
$consult = "select active from $table where login=''$_REQUEST[login]'' and password=''$_REQUEST[password]''";
$result=mysql_query($consult,$link);
$numreg=mysql_numrows($result);
if($numregi!=0)
{
$_REQUEST[''active'']=mysql_result($result,$i,''active'');
if ($_REQUEST[''active'']==''1'')
{
echo "Admin";
?>
<A href=''menuadmin.php''>Continue</a>
<?php
}
else
{
echo "User";
?>
<A href=''coment.php''>Continue</a>
<?php
}
}
else
{
echo "Login or password incorrect";
echo " <a href=''index.php''>Try again";
}
}
else
{
echo "Login or password incorrect";
echo " <a href=''index.php''>Try again";
}
?>
和coment.php
这是一种提交评论的表单,它确实有很多,问题是,当我转到coment.php时,我可以看到该表单并提交,即使我还没有登录,我如何显示一条消息,说我没有loggen如果我直接进入coment.php?
and coment.php

推荐答案
_REQUEST [''login'']!="和
_REQUEST[''login'']!="" and
_REQUEST [''password' ']!=") {
_REQUEST[''password'']!="") {
table ="users"; require(''conect.php'');
table = "users"; require(''conect.php'');
