我想做的就是将 html 注入转义到我的输入文本框中。我没有正确使用 htmlentities 吗?
代码:
<?php
require_once "pdo.php";
// Demand a GET parameter
if ( ! isset($_GET['name']) || strlen($_GET['name']) < 1 ) {
die('Name parameter missing');
} else {
$username = $_GET['name'];
}
// If the user requested logout go back to index.php
if ( isset($_POST['logout']) ) {
header('Location: index.php');
return;
}
$year = isset($_POST['year']) ? $_POST['year'] : '';
$mileage = isset($_POST['mileage']) ? $_POST['mileage'] : '';
$make = isset($_POST['make']) ? $_POST['make'] : '';
$failure = false;
$success = false;
if ( isset($_POST['make']) && isset($_POST['year'])
&& isset($_POST['mileage'])) {
//$year = $_POST['year'];
//$mileage = $_POST['mileage'];
//$make = $_POST['make'];
if ( strlen($make) < 1){
$failure = "Make is Required";
} else {
if (is_numeric($year) and is_numeric($mileage) ){
error_log("year is a number ".$_POST['year']);
error_log("Mileage is a number ".$_POST['mileage']);
$sql = "INSERT INTO autos (make, year, mileage)
VALUES (:make, :year, :mileage)";
$stmt = $pdo->prepare($sql);
$stmt->execute(array(
':make' => $make,
':year' => $year,
':mileage' => $mileage));
$success = "Record Inserted";
} else {
$failure = "Mileage and Year must be numeric";
error_log("year or mileage is not a number year=".$_POST['year']);
error_log("Mileage or year is not a number mileage=".$_POST['mileage']);
}
}
}
输出不会转义见截图:
