Answer 1

$sql = mysql_query("SELECT * FROM property WHERE posthead = '".$search."' OR requestto= '".$search."' OR ptype= '".$search."' OR requestby = '".$search."' OR owner= '".$search."' OR bed = '".$search."' OR bath= '".$search."' OR price= '".$search."' OR sqft,descp = '".$search."'");

and change $result = (mysql_fetch_array($sql)); to $result = (mysql_fetch_assoc($sql));

NOTE :

1. your query is vulnerable to sql injection
2. mysql_* functions are deprecated use mysqli_* or PDO

Answer 2

TRY THIS:

Better is to use "CONCAT" for the columns:

$sql = mysql_query("SELECT * FROM property WHERE CONCAT(posthead,requestto,ptype,requestby,owner,bed,bath,price,sqft,descp) LIKE "%.$search."%'");

OR will work but CONCAT can reduce query size.

Answer 3

尝试SELECT * FROM property WHERE posthead = $search OR requestto = $search ...等

Answer 4

Since you are creating a searching form you might want to be able to find records by partial match and not exact word. In order to do that you can use LIKE

$q = "SELECT * FROM property 
WHERE posthead  LIKE '%$search%' OR
      requestto LIKE '%$search%' OR
      ptype     LIKE '%$search%' OR
      requestby LIKE '%$search%' OR
      owner     LIKE '%$search%' OR
      bed       LIKE '%$search%' OR
      bath      LIKE '%$search%' OR
      price     LIKE '%$search%' OR
      sqft      LIKE '%$search%' OR
      descp     LIKE '%$search%'";

$sql = mysql_query($q);
