[英]$_POST Undefined index: Error
表格:
<form action="/HW2/controllers/login.php" id = "login-box" method = "post">
Username: <input type="text" name='user'><br>
Password: <input type="text" name='pwd'><br>
<input type="submit">
</form>
那個行動:
<?php
require("../config/config.php");
if(isset($_POST['user']) && isset($_POST['pwd'])){
if(strcmp($_POST['user'], USERNAME) == 0 && strcmp($_POST['pwd'],
PASSWORD) == 0){
session_start();
$_SESSION['logon'] = true;
echo "success";
//header("location: /HW2/index.php?view=loggedin");
}else{
print_r("Sorry, your username and/or password are invalid. Try Again?");
//header("location: /HW2/index.php?view=loginPage");
}
}else{
print_r("Post data not sent.");
}
?>
我嘗試了許多不同的方法,所有的結果都導致“未發送郵政數據”。(如果我嘗試訪問$ _POST值,則也稱為“未定義索引:”)試圖查找我已經搞砸了好幾個小時了,感謝任何幫助,我對php完全了解,這可能是非常簡單和愚蠢的事情。
提前致謝!
我認為無需使用最后一個“ else”
僅使用
if(isset($_POST['user']) && isset($_POST['pwd'])){
if(strcmp($_POST['user'], USERNAME) == 0 && strcmp($_POST['pwd'],
PASSWORD) == 0){
session_start();
$_SESSION['logon'] = true;
echo "success";
//header("location: /HW2/index.php?view=loggedin");
}else{
print_r("Sorry, your username and/or password are invalid. Try Again?");
//header("location: /HW2/index.php?view=loginPage");
}
}
<?php
error_reporting(E_ALL ^ E_NOTICE);
require("../config/config.php");
if(isset($_POST['user']) && isset($_POST['pwd'])){
if(strcmp($_POST['user'], USERNAME) == 0 && strcmp($_POST['pwd'],
PASSWORD) == 0){
session_start();
$_SESSION['logon'] = true;
echo "success";
//header("location: /HW2/index.php?view=loggedin");
}else{
print_r("Sorry, your username and/or password are invalid. Try Again?");
//header("location: /HW2/index.php?view=loginPage");
}
}else{
print_r("Post data not sent.");
}
?>
error_reporting(E_ALL ^ E_NOTICE); 顯示錯誤但隱藏通知。 未定義的索引表明$ _POST變量被調用而沒有值,因此這是第一個選項。 第二種選擇是修改代碼。
風景:
<form action="/HW2/controllers/login.php" id = "login-box" method = "post">
Username: <input type="text" name='user'><br>
Password: <input type="text" name='pwd'><br>
<input type="submit" name = "submit" value = "Submit">
</form>
郵遞區號:
<?php
require("../config/config.php");
if(isset($_POST['submit'])){
if(strcmp($_POST['user'], USERNAME) == 0 && strcmp($_POST['pwd'],
PASSWORD) == 0){
session_start();
$_SESSION['logon'] = true;
echo "success";
//header("location: /HW2/index.php?view=loggedin");
}else{
print_r("Sorry, your username and/or password are invalid. Try Again?");
//header("location: /HW2/index.php?view=loginPage");
}
}else{
print_r("Post data not sent.");
}?>
嘿,謝謝大家的回答,原來,在我重新啟動計算機並小睡之后,我的代碼工作正常。
我的猜測是chrome或apache錯誤地處理了$ _POST變量,但是我不是很有經驗,所以我只是在吐口水。 無論哪種方式,我的代碼都可以完成我現在想要的工作。
仍然感謝您的幫助!
