Question

I’m getting error on this:

Deprecated: Function split() is deprecated in C:\xampp\htdocs\tet\search_motifasni2.php on line 10

Notice: Undefined variable: sql in C:\xampp\htdocs\tet\search_motifasni2.php on line 18

Warning: mysql_num_rows() expects parameter 1 to be resource, boolean given in C:\xampp\htdocs\tet\search_motifasni2.php on line 32
doc with term:

Codes:

if (isset($_POST['Submit']))
{

        //retrieve search word, trim, remove duplicate
        $find = $_POST['find'];
        $find = ltrim($find);
        $find = rtrim($find);
        $find = split(" ",$find);//line 10
        $find = array_unique($find); 

. . .

        if($val<>" " and strlen($val)>0)
        {
            $sql .=" Terms = '$val' or";//line 18
        }
    }

. . .

    $query = "SELECT * FROM document";
    $result = mysql_query($query);
    $num = mysql_num_rows($result);//line 32

Tried many ways but still getting the same result when searched a query.

Answer 1

First, split is deprecated: instead use explode. (like this: $find = explode(' ', $find); which is basically the same)
Also, you use both ltrim and rtrim, I think you could just as well use trim, which does both.

The second error is thrown because the $sql variable you use is not yet defined on line 18, you can’t concatenate a string to a variable that is not yet defined (actually you can, because php is very humble, but it’s not nice)
It can be easily solved by putting $sql = ''; before the if statement.

The last error means mysql_num_rows gets false as an argument, while it needs a mysql resource. $result is false, so mysql_query returns false, which it does when there’s an error while executing the query, see here. Does your table document exist?
