我目前正在为我的网站开发个人资料页面。到目前为止，除了在编辑个人资料页面上，一切都进行得很顺利。数据库似乎没有像它应该的那样更新变量，我也不知道为什么。有3个主要的代码块，我认为实际的输入部分是问题所在。
在此之前，变量不会更新，但在代码块之后，变量会更新（这是一种形式）。顺便说一句，如果你想知道问题是什么，就在这里。如果用户输入了一些内容，但随后删除了它，它会在表单提交中重新输入数据。现在，这里是3个主要的代码块（按顺序）：
启动
function utf8_encode_string($value) {
if (empty($_POST[$value])) {
$str = "";
return $str;
}
else {
$str = utf8_encode(htmlspecialchars(trim($_POST[$value]), ENT_QUOTES));
return $str;
}
}
//Grabs all of the profile information
$accountinfoquery = "SELECT * FROM users WHERE username = :username";
$accountinfoparams = array(':username' => $accounturl);
try{
$accountinfostmt = $connection->prepare($accountinfoquery);
$accountinforesult = $accountinfostmt->execute($accountinfoparams);
}
catch(PDOException $ex){
echo ("Failed to run query: " . $ex->getMessage());
}
$accountinfocolumns = $accountinfostmt->fetch();
$firstnameinput = utf8_encode_string("firstname");
$lastnameinput = utf8_encode_string("lastname");
$ageinput = utf8_encode_string("age");
$locationinput = utf8_encode_string("location");
$quoteinput = utf8_encode_string("quote");
$genderinput = utf8_encode_string("gender");
$aboutinput = utf8_encode_string("about");
if (!$firstnameinput) {
$firstnameinput = utf8_encode(htmlspecialchars(trim($accountinfocolumns["firstname"]), ENT_QUOTES));
}
if (!$lastnameinput) {
$lastnameinput = utf8_encode(htmlspecialchars(trim($accountinfocolumns["lastname"]), ENT_QUOTES));
}
if (!$ageinput) {
if ($accountinfocolumns["age"] == "0") {
$ageinput = "";
}
else {
$ageinput = utf8_encode(htmlspecialchars(trim($accountinfocolumns["age"]), ENT_QUOTES));
}
}
if (!$locationinput) {
$locationinput = utf8_encode(htmlspecialchars(trim($accountinfocolumns["location"]), ENT_QUOTES));
}
if (!$quoteinput) {
$quoteinput = utf8_encode(htmlspecialchars(trim($accountinfocolumns["quote"]), ENT_QUOTES));
}
if (!$genderinput) {
$genderinput = utf8_encode(htmlspecialchars(trim($accountinfocolumns["gender"]), ENT_QUOTES));
}
if (!$aboutinput) {
$aboutinput = utf8_encode(htmlspecialchars(trim($accountinfocolumns["about"]), ENT_QUOTES));
}
//Final Check
$firstnamefinalcheck = False;
$lastnamefinalcheck = False;
$agefinalcheck = False;
$locationfinalcheck = False;
$quotefinalcheck = False;
$aboutfinalcheck = False;
输入

请参阅块3中的代码。我发现参数id尚未绑定。
因此，如果可以帮助您，请在执行之前绑定参数：
$datasend->bindParam(':id', $id);
$datasend->execute();
<?php
....................
$inputquery = "UPDATE users SET quote = :quote, WHERE id = :id";
$datasend = $connection->prepare($inputquery);
$datasend->bindParam(':id', $id);
$datasend->execute();
....................
?>
编辑&更新：
将session_start放在上面的位置，如：
<?php
//Stars the sessions
session_start();
//Makes sure the user is trying to edit there profile
if (!isset($_SESSION["logged_in"])) {
header("Location: http://localhost/postin'/home.php");
exit();
}
......................

很难确定您的直接问题，因为您已经发布了很多代码。所以，我会添加另一个需要修复的东西，以防有帮助。
不要这样做：
include("C:'wamp'www'postin''includes'header.php");
首先，括号在大多数情况下是不必要的（除非你需要一个返回值，而你在这里没有），所以它现在变成了：
include "C:'wamp'www'postin''includes'header.php";
现在，最好不要硬连接完整的目录路径，所以再次将其更改为这样的内容（如果您执行了多个操作，则只有一个$root）：
$root = __DIR__;
include $root . "'postin''includes'header.php";
此外，虽然这将在Windows上工作，但您可能会遇到具有特殊含义的转义符的问题，例如换行符的"''n"）。因此，使用正斜杠，这将使这项工作在Windows，OSX和Linux上也很好。PHP将对反斜杠进行必要的转换：
$root = __DIR__;
include $root . "/postin'/includes/header.php";
我想说postin'撇号也是在找麻烦（尽管这可能不是你眼前问题的原因）。如果你真的需要那种非标准的URL字符，我会使用URL重写。
