Question

v.push_back(*std::istream_iterator<int>(std::cin));

我正在寻找最终将我的搜索框挂钩到这个无法正常工作的查询，我试图将查询添加到下面用于测试目的：

include("config.php");
$page_number = filter_var($_POST["page"], FILTER_SANITIZE_NUMBER_INT, FILTER_FLAG_STRIP_HIGH);

if(!is_numeric($page_number)){
  header('HTTP/1.1 500 Invalid page number!');
  exit();
}
session_start();
$position = (($page_number-1) * $item_per_page);

if(!empty($_SESSION['type'])){
  $typesql = $_SESSION['type'];
  $results = $mysqli->prepare("SELECT name, location, score, img, id, type FROM artists WHERE type = ? ORDER BY score DESC LIMIT ?, ?");
  $results->bind_param("sii", $typesql, $position, $item_per_page);
  $results->execute();
  $results->bind_result($name, $location, $score, $img, $id, $type);
} else {
  $results = $mysqli->prepare("SELECT name, location, score, img, id, type FROM artists ORDER BY score DESC LIMIT ?, ?");
  $results->bind_param("ii", $position, $item_per_page);
  $results->execute();
  $results->bind_result($name, $location, $score, $img, $id, $type);
}

// Le fetch
  while($results->fetch()){
    //my cards here
  }
  ?>

我的名字中有“etc”，但我得到的结果是：

SELECT name, location, score, img, id, type FROM artists WHERE name LIKE '%etc%' ORDER BY score DESC LIMIT ?, ?

如何更改此查询以将来自搜索框的$ _GET结果绑定到该查询，该网站为Setch.me

与this question中一样，你可以在mysqli中使用带有绑定参数的LIKE：

$param = "%{$_POST['searchphrase']}%";
$stmt = $mysqli->prepare("SELECT name, location, score, img, id, type FROM artists WHERE name LIKE ?");
$stmt->bind_param("s", $param);
$stmt->execute();
$stmt->bind_result($name, $location, $score, $img, $id, $type);

无法将LIKE添加到我的SQL查询中
