Re: [PHP] Newbie: PHP/MySQL (SELECT)
if one of $titulotxt or $cdstxt is not set, your query will look
something like this:
SELECT * FROM divx WHERE && cds like '$cdstxt' ORDER BY titulo
As you see, there is unnecessery &&. I build my search queries using
this form:
$query_cond='';
foreach($_GET as $col => $val) {
switch($col) {
case 'cds': // you can add more cases here for conditions that
need to be exact
$query_cond .= " $col LIKE '$val' AND ";
break;
case 'titulo': // you can add more cases here for conditions
that need not to be exact
$query_cond .= " $col LIKE '%$val%' AND ";
break;
}
}
// get rid of final AND
$query_cond = substr($query_cond, 0, strlen($query_cond) - 4);
// and as you don't have any other conditions, $query_cond cannot be
empty - we would have excessive WHERE
// so if it is empty, make it 1
if($query_cond=='') $query_cond='1';
$sql="SELECT * FROM divx WHERE $query_cond ORDER BY titulo";

The question is that i have two search fields (titulotxt and cdstxt) and i
want to create an mysql condition... i trying:
$sql1=($titulotxt) ? "titulo like '%".$titulotxt."%'":"";
$sql2=($cdstxt) ? "cds like '$cdstxt'":"";
$sql="SELECT * FROM divx WHERE" .$sql1 " && " .$sql2 " ORDER BY titulo";
but he's giving me a sintax error on the 3 line... Can anyone
teach me how i must do to validate the mysql condition and make it work?
Thanks

Can anyone >teach me how i must do to validate the mysql condition and make it work? [snip] As already said, put a space after the WHERE clause. What happens if $sql1 or $sql2 are empty (as your example provisons)? Create an $sql3 that combines $sql1 and $sql2, and construct your SQL accordingly: $sql1 = ($titulotxt ? null : "titulo like '%$titulotxt%'"); $sql2 = ($cdstxt? null : "cds like '$cdstxt'"); $sql3 = $sql1 . ($sql1 && $sql2 ? ' AND ' : null) . $sql2; $sql = 'SELECT * FROM divx ' . ($sql3 ? "WHERE $sql3 " : null) . 'ORDER BY titulo'; -- >O Ernest E.

RE: [PHP] Newbie: PHP/MySQL (SELECT)
$sql1 = "titulo like '%$titulotxt%'" $sql2 = "cd like '$cdstxt'"; $sql = "SELECT * FROM divx WHERE $sql1 AND $sql2 ORDER BY titulo"; I think you are getting the error because of the ($titulotxt) ? portion of your sql statements. You really only need the two statements listed above and then put into your actual sql statement.

and add a space after the WHERE.
Also consider the positioning of the single quotes (') and double-quotes (")
in the $sql1 assignment statement - they must be nested.
Finally, consider echoing sql1, $sql2, and $sql to be able to see with your
own eyes!
