PHP/mySQL Like函数不起作用

Question

我在PHP中有一个简单的查询,但我无法开始Like工作.

这是代码:

$var = $_GET['q'];
$trimmed = trim($var);
$query = "SELECT * FROM vm_regiony WHERE nazev LIKE "%$trimmed%" order by id     LIMIT 10";
$result = mysql_query($query);
if(mysql_num_rows($result)==0){
  echo "nothing";
  echo "<br />";
  echo $trimmed;
}else{
  while($rene=mysql_fetch_array($result)){
    $jmeno = $rene['nazev'];
    echo '<a id="hled" onclick="javascript:vybrat()">'.$jmeno.'</a>';

Answer 1

对于一个你需要在那里使用单引号

$query = "SELECT * FROM vm_regiony WHERE nazev LIKE '%$trimmed%' order by id LIMIT 10";
