PDO $query.= + WHERE IN

[contemplatrice]

Hola a todos, Buenas,

Llevo 2 días luchando con SELECT WHERE IN en pdo....
Quiero que mysql devuelva los resultados correspondientes a los valores seleccionados en mi multiselect

Código HTML:

 <select multiple="multiple" name="secteur_searched[]" >
      <option value="1">Accueil - Secrétariat - Fonctions Administratives</option>
      <option value="2">Achats - Juridique - Qualité; - RH - Direction</option>
     etc...
    </select> 

y/o en mis checkboxes

Código HTML:

<input type="checkbox" name="type_de_contrat[]" value="CDI" >      
 <input type="checkbox" name="type_de_contrat[]" value="CDD" > 

He visto que un array dentro de WHERE IN en pdo tiene que escribirse myArray =('1','2','3','4'), pero ¿cómo conseguir esta sintaxis desde un multiselect[] ? o unas checkboxes[] ? ¿ Y que poner en $param[]...?

Muchísimas gracias por anticipado,

Código:

$query =  "SELECT * FROM marinterim_job_offers j 
          JOIN marimmo_villes v ON v.ville_id =j.job_ville  ";

     }
