save checkbox values with pdo in mysql db

save checkbox values with pdo in mysql db

I can't save the values in checkbox into my db...always save "array" and
not the values..

save.php file the values change to array... can you give me a hand with
this please?
here is the form:
<form name="esq" id="esq" method="post">
<div class="row-fluid grid">
<div class="span4">
<label><b><?php echo $translate->__('Gestas Previas'); ?>:
</b></label><input type="text" class="span3" value="" name="gestas"
/></div>
<div class="span4">
<label><b><?php echo $translate->__('Abortos'); ?>: </b></label><input
type="text" class="span3" value="" name="abortos" /></div>
<div class="span4">
<label><b><?php echo $translate->__('3 espontaneos consecutivos'); ?>:
</b></label><input type="text" class="span3" value="" name="esp_conse"
/></div>
</div>
----------HERE START THE CHECKBOX-------------
<div class="row-fluid grid">
<label class="control-label"><b><?php echo $translate->__('Ultimo
Previo'); ?></b></label>
<div class="controls">
<label class="checkbox inline">

here is the code:
<?php
include_once("confs.php");
if (!empty($_POST)) {
try{
$statement = $conn->prepare("INSERT INTO GESTACION (gestas, abortos,
esp_conse, seleccion, partos, vaginal, cesareas, nac_vivos,
nac_muertos, viven, semana, des_semana, f_ult_parto, f_ult_pap, fur,
fpp, edad_gesta, pesofeto, tallafeto, imc, toxoide, influenza, otras,
medicament) VALUES (?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?,
?, ?, ?, ?, ?, ?, ?)");
if ($statement->execute(array($_POST['gestas'], $_POST['abortos'],
$_POST['esp_conse'], $_POST['seleccion'], $_POST['partos'],
$_POST['vaginal'], $_POST['cesareas'], $_POST['nac_vivos'],
$_POST['nac_muertos'], $_POST['viven'], $_POST['semana'],
$_POST['des_semana'], $_POST['f_ult_parto'], $_POST['f_ult_pap'],
$_POST['fur'], $_POST['fpp'], $_POST['edad_gesta'],
$_POST['pesofeto'], $_POST['tallafeto'], $_POST['imc'],
$_POST['toxoide'], $_POST['influenza'], $_POST['otras'],
$_POST['medicament'])));
$dbSuccess = true;
} catch (Exception $e) {
$return['databaseException'] = $e->getMessage();
}
$dbh = null;
}
?>
all other data save nice into db.
