Question

I m using this code to be able to generate an dynamic select: demo: http://www.erichynds.com/examples/jquery-related-selects code: https://github.com/ehynds/jquery-related-selects

我已经从以下几处修改了国文法:

$counties = array();
$counties[ 1 ][ BARN ] =  Barnstable ;
$counties[ 1 ][ PLYM ] =  Plymouth ;
$counties[ 2 ][ CHIT ] =  Chittenden ;
$counties[ 3 ][ ANDE ] =  Anderson ;

To

$counties = array();
$sql = "SELECT
        id,
        naam,
        klant_id
        FROM contactpersoon
        ORDER BY klant_id ASC ";

if(!$res = mysql_query($sql,$con))
{
    trigger_error(mysql_error(). <br />In query:  .$sql);
}
else
{
    while ($row = mysql_fetch_array($res))
    {
        $counties[$row[ klant_id ][$row[ id ] =  htmlentities($row[ naam ]); 
    }
}

But for some reason the pulldown select list is not created when the changes are made. When I test the query, no errors shown.

存在错误,至少在你所贴的法典中。你的方括号似乎被排除在外。

$counties[$row[ klant_id ][$row[ id ] =  htmlentities($row[ naam ]);

应当

$counties [$row[ klant_id ]] [$row[ id ]] =  htmlentities($row[ naam ]);

或

$a = $row[ klant_id ];
$b = $row[ id ];
$counties[a][b]= htmlentities($row[ naam ]);
