[michalopek100]

how to pass value from list/menu in a form without any submit button . (when you choose value from list/menu it posts it without submition)
can anybody help me?
let's say I have such html code:

<form method="post" action="">
<select type="submit" name="studia_rodzaj" size="1">
<option value="x">x</option >

<option value="y">y</option>
<option value="z">x</option>
</select>
<input type="submit" name="Submit" value="Submit">

</form>

This isnt a PHP issue. Try Javascript. w3schools.com has good tutorial on using Javascript.

is this now?

<form method="post" action="">
<select type="submit" name="studia_rodzaj" size="1">
<option value="<?echo $POST["studia_rodzaj"];?>"><?echo str_replace("", " ",$POST["studia_rodzaj"]);?></option>
<? if(!($POST["studia_rodzaj"]== "studia_dzienne")){?><option value="studia_dzienne">studia dzienne</option><?;};?>
<? if(!($POST["studia_rodzaj"]== "studia_zaoczne")){?><option value="studia_zaoczne">studia zaoczne</option><?;};?>
<? if(!($POST["studia_rodzaj"]== "studia_licencjackie")){?><option value="studia_licencjackie">studia licencjackie</option><?;};?>
</select>
<input type="submit" name="Submit" value="Submit">

</form>

<form name="studia_rodzaj_menu" method="post" action="">
<select type="submit" name="studia_rodzaj" size="1" onchange="javascript:document.studia_rodzaj_menu.submit();">
<option value="<?echo $POST["studia_rodzaj"];?>"><?echo str_replace("", " ",$POST["studia_rodzaj"]);?></option>
<? if(!($POST["studia_rodzaj"]== "studia_dzienne")){?><option value="studia_dzienne">studia dzienne</option><?;};?>
