Question

есть два выезжающих списка, оба заполняются из базы, но по второму хотелось выборочно выводить, т.е. первый select дает выбор марки авто, а второй уже конкретно модель авто.

<select name="myselect">

<?php

$resultmarka = mysql_query("select * from marka ");

$mymarka = mysql_fetch_array($resultmarka);

do{printf("<option value='%s' >%s</option>",$mycar["id_car"], $mycar["name_marka"]);

}

?>

</select>

а как можно использовать в этой же форме "myselect"

<select name="myselect2">

<?php

$resultmodel = mysql_query("select * from model WHERE id_marka = "myselect"");

$mymodel = mysql_fetch_array($resultmodel);

do{printf("<option value='%s' >%s</option>",$mycar["id_model"], $mycar["name_model"]);

}

?>

</select>
