我正在处理需要密码长度在6到25个字符之间的表单。用户名和全名不得超过25个字符。用户名和全名部分工作正常，但是当我输入一个长度为10个字符的密码时，它将我的错误代码作为小于6的回声。我该怎么做？最小和最大强度长度
请看看代码，请帮助我： 问题是在该地区评论为/ /检查密码长度。由于EVERONE
PHP代码为：
<?php
echo "<h1>Register</h1>";
$submit = filter_input(INPUT_POST, 'submit');
//form data
$fullname = strip_tags (filter_input(INPUT_POST, 'fullname'));
$username = strip_tags (filter_input(INPUT_POST, 'username'));
$password = strip_tags(filter_input(INPUT_POST, 'password'));
$repeatpassword = strip_tags(filter_input(INPUT_POST, 'repeatpassword'));
$date = date("Y-m-d");
if ($submit)
{
//check for existence
if($fullname&&$username&&$password&&$repeatpassword)
{
$password = md5($password);
$repeatpassword = md5($repeatpassword);
if ($password==$repeatpassword)
{
//check char length of username and fullname
if (strlen($username)>25||strlen($fullname)>25)
{
echo "Length of username or full name is too long!";
}
else
{
//check password length
if (strlen ($password)>25 || strlen ($password)<6)
{
echo "Password must be between 6 and 25 characters";
}
else
{
//register user
}
}
}
else echo "Your passwords do not match";
}
else echo "Please fill in <b>all</b> fields!";
}
?>`
和HTML是：
<html>
<form action='register.php' method='POST'>
<table>
<tr>
<td>
Your full name:
</td>
<td>
<input type='text' name='fullname'>
</td>
</tr>
<tr>
<td>
choose a username:
</td>
<td>
<input type='text' name='username'>
</td>
</tr>
<tr>
<td>
Choose a password:
</td>
<td>
<input type='password' name='password'>
</td>
</tr>
<tr>
<td>
Repeat your password:
</td>
<td>
<input type='password' name='repeatpassword'>
</td>
</tr>
<table>
<p>
<input type='submit' name='submit' value='Register'>
这个问题似乎是题外话，因为它已经过时了。 – 2014-10-15 14:39:01
