SQLSTATE [42000] SELECT

Question

Goog morning all

我的代码明显有问题

这里是：

<fieldset>
 <?
 if(isset($_POST['requete']) && $_POST['requete'] != NULL){
  include "connexion.inc";
  $reponse = $bdd->query('SELECT id_piece, piece 
  FROM tbl_piece 
  WHERE piece = '.$requete.' ');
  while($donnees = $reponse->fetch()){
   echo $donnees['id_piece'];
  }
 }
 else{
  echo $requete;
 }
 ?>         
 <form method="post" action="standard.php">
 <input type="text" name="requete">
 <input type="submit" value="Rechercher">
 </form>
 </fieldset>

当我在文本框的网页中输入“TL081”之类的内容时，请验证

我接受了这个错误：

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[42000]: Syntax error or access violation: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1' in /home/libtronic/www/html/standard.php:48 Stack trace: #0 /home/libtronic/www/html/standard.php(48): PDO->query('SELECT id_piece...') #1 {main} thrown in /home/libtronic/www/html/standard.php on line 48

经过一些搜索，我的问题来自于这个=＆gt; '$ requete。' 我试着把.$requete.或'“。$ requete。”'或者其他但是没有用

有人可以帮我吗？

尝试更换行

$reponse = $bdd->query('SELECT id_piece, piece 
FROM tbl_piece 
  WHERE piece = '.$requete.' ');

带

$reponse = $bdd->query("SELECT id_piece, piece 
  FROM tbl_piece 
  WHERE piece = '".$requete."'");
