Answer 1

You have some wrong quotes and use concat for the like string

"SELECT * 
  FROM  pvl_posts 
  WHERE (title LIKE concat('%', '$title','%') OR post LIKE concat('%','$title' ,'%') )
  OR (title LIKE concat('%' , '$post', '%')   OR post LIKE concat('%','$post','%') )
  AND id != '$id'"

Answer 2

请尝试以下操作：

$rela=mysql_query("SELECT * FROM  pvl_posts WHERE (title LIKE '%".$title."%' OR post LIKE '%".$title."%') OR (title LIKE '%".$post."%' OR post LIKE '".$post."') AND id != '".$id."'");

试试这个，有两个' ，删除它。

$rela=mysql_query("SELECT * FROM  pvl_posts WHERE (title LIKE '%$title%' OR post LIKE '%$title%') OR (title LIKE '%$post%' OR post LIKE '%$post%') AND id != '$id'");

Answer 4

Kindly show your mysql connection string. here is an example:

<?php
$mysqli = new mysqli("localhost", "root", "", "database_name");
$query = "SELECT * FROM  pvl_posts WHERE (title LIKE '%$title%' OR post LIKE '%$title%') OR (title LIKE '%$post%' OR post LIKE '%$post%') AND id != '$id'";
$rows = $mysqli->query($query);
if ($rows->num_rows > 0) {
    while ($row = $rows->fetch_assoc()) {
        // do something with row variable here.
        var_dump($row);
    }
}
?>

Try it out.
