问题描述
因此,我正在使用PHP构建发布系统。 当用户想要创建帖子时,所有字段都需要填写,而我想做的就是将会话的名称插入数据库,例如,插入数据库“ Edward”,因为那将是会话的名称。 这是我想要做的:
<?php
session_set_cookie_params(86400*30,"/");
session_start();
require 'admin/config.php';
require 'functions.php';
if (isset($_SESSION['user'])) {
require 'view/new.view.php';
} else {
header('Location: index.php');
}
$connection = connect($bd_config);
if (!$connection) {
header('Location: error.php');
}
$errors = '';
if ($_SERVER['REQUEST_METHOD'] == 'POST') {
$title = cleanData($_POST['title']);
$demo = cleanData($_POST['demo']);
@$project_type = $_POST['project_type'];
$content = $_POST['content'];
$post_by = $_SESSION['user'];
$errors = '';
if (empty($title) or empty($demo) or empty($project_type) or empty($content)) {
$errors .= '<p>Complete all the fields!</p>';
} else {
$statement = $connection->prepare("
INSERT INTO posts (ID,title,demo,content,post_type)
VALUES (null,:title,:demo,:content,:project_type)
");
$statement->execute(array(
':title' => $title,':demo' => $demo,':project_type' => $project_type,':content' => $content,));
$statement2 = $connection->prepare("
INSERT INTO posts (post_by)
VALUES ($post_by)
");
$statement2->execute(array(
$post_by
));
header('Location: main.php');
}
}
?>
如您所见,我正在为2个SQL咨询执行2个statement
变量,但是当我这样做时,它会引发以下错误:
<b>Fatal error</b>: Uncaught PDOException: SQLSTATE[42S22]: Column not found: 1054 Unknown column 'cesar' in 'field list' in C:\xampp\htdocs\bider\test2\new.php:52
Stack trace:
#0 C:\xampp\htdocs\bider\test2\new.php(52): PDOStatement->execute(Array)
#1 {main}
thrown in <b>C:\xampp\htdocs\bider\test2\new.php</b> on line <b>52</b><br />
我猜这是'cesar'原因,因为这是会话名称。 有人可以帮忙吗?
