Meerdere problemen met php/css script
Ben bezig met een site te maken voor een maat van me, ik ben totaal een leek in het ontwerpen en codes.
Zoals op de afbeelding staat, de searchform, moet op de zelfde lijn komen als Home, Shop, Mijn Account en Contact. Ik heb van alles al geprobeerd, maar krijg het niet voor elkaar.

<?php
}
add_action ('omega_after_primary_menu','shopping_menu_search');
function shopping_menu_search() {
?>
<form method="get" id="searchform" action="<?php echo home_url(); ?>/">
<div align="right"><input type="text" name="s" id="s" placeholder="Zoeken" />
<input type="submit" id="searchsubmit" value="Zoeken" class="btn" />
</div>
</form>
<?php
}?>
}
add_action ('omega_after_primary_menu','shopping_menu_search');
function shopping_menu_search() {
?>
<form method="get" id="searchform" action="<?php echo home_url(); ?>/">
<div align="right"><input type="text" name="s" id="s" placeholder="Zoeken" />
<input type="submit" id="searchsubmit" value="Zoeken" class="btn" />
</div>
</form>
<?php
}?>
Ik heb 'omega_after_primary_menu' al aangepast naar 'nav-primary', 'menu-item' en nog een heleboel, gewoon aan het proberen geweest, maar ik krijg het maar niet voor elkaar.
Met het andere probleem heb ik proberen te zoeken waar ik het kan oplossen, maar ik kan nergens iets vinden wat me zeg, he! Daar moet ik eens gaan kijken...
Ik gebruik overigs Wordpress, met de WooCommerce plugin en Shopping Theme van Themehall.com. Daar heb ik het forum ook al geraadpleegd, maar heb nog geen antwoord gekregen.
Ik hoop dat jullie mij kunnen helpen! :)
Gr,
Martijn
Gelieve in het vervolg bij code de [code][/code]-tags gebruiken.
Hier kan je meer lezen over de mogelijke opmaakcodes.
Alvast bedankt![/modedit]

Je laat helaas helemaal geen HTML of CSS zien van de navigatiebalk.
Dit volgende is echt niet meer van deze tijd:

De HTML code moet ik nog vinden, zal hier achter aan gaan.
Bedankt voor je hulp zo ver.
Ik zou inderdaad me eigen er eens goed in moet gaan verdiepen en zo mijn kennis op doen :).
Edit.
Ik heb even gekeken, ik denk dat het gevonden moet worden in een php bestand van Wordpress.
Hier onder is de volledige code van nav-menu.php
