$username = $_POST['username'];
$ppassword = $_POST['password'];
$password = md5("$ppassword");
这是代码,我收到此错误
Notice: Undefined index: username in C:'wamp'www'php'compare.php on line 14

这是表格:
<form name="form1" method="post" action="compare.php">
<strong><input id="close" type="button" value="X"
onclick="getElementById('loginbox').style.display = 'none'">Member Login</strong></br>
Username:<input name="username" type="text" id="username"></br>
Password:<input name="password" type="password" id="password">
</br>
<input type="submit" name="Submit" value="Login">
</form>
我让它工作,但是当他们将 php 更新到 5.4.12 时,它停止了,我不得不更改它。
你可以
做这样的事情——
$username = isset($_POST['username']) ? $_POST['username'] : '';
$password = isset($_POST['password']) ? md5($_POST['password']) : '';
使用 isset() 函数来检查变量集与否?
$username = isset($_POST['username']) ? $_POST['username'] : '';
$password = isset($_POST['password']) ? md5($_POST['password']) : '';
你的 html 代码放到这里,确保你的 html 文本字段名称应该与 $_POST['variable_name'] 匹配
例如,
如果您在 html 表单的同一页面中有此代码,则需要以下内容:
if(isset($_POST['password']) && isset($_POST['username'])){
$username = $_POST['username'];
$ppassword = $_POST['password'];
$password = md5("$ppassword");
}
如果您在其他页面中有此代码,请确认您是否收到带有
echo $_POST['username'];
echo $_POST['password'];
如果不是,则输入错误
<form action="somepage.php" method="post">
<input type="text" name="username" value="" />
<input type="password" name="password" value="" />
<input type="submit" name="submit" value="Submit" />
</form>
