insert more than one array using one query - php

Question

I want to insert an array of checkboxes, dropdowns, and dates into database. If I checked all the checkbox, all works fine. However, when I checked certain checkboxes, the value of checkboxes can be inserted but not the value of dropdown and date.
This is code for the checkbox, dropdown, and date:
<div class='field'>
<div class='checkboxes'>
<div class='checkbox'>
<input type='checkbox' id='spesimen$i' name='spesimen[]' value='$JenisSpesimen' required minlength='1'/><label>$JenisSpesimen</label><br>
</div>
<div class='select'>
<select id='bilangan$i' name='bilangan[]' class='med' style='display: none;'>
<option></option>
<option value='Pertama'>Pertama</option>
<option value='Kedua'>Kedua</option>
</select>
</div>
<br>
<div class='input' id='tarikh_ambil$i' style='display: none;'>
<input type='text' id='tarikh_ambil_spesimen$i' name='tarikh_ambil_spesimen[]' class='small' readonly/>
</div>
</div>
</div>
And this the process:
$spesimen = $_POST['spesimen'];
$countSpesimen = count($_POST['spesimen']);
$bilangan = $_POST['bilangan'];
//$countBilagan = count($_POST['bilangan']);
$tarikh_ambil = $_POST['tarikh_ambil_spesimen'];
//$countTarikh = count($_POST['tarikh_ambil_spesimen']);
for ( $x = 0; $x < $countSpesimen; $x++)
{
$xx = $x+1;
$SubIDMohon = $IDMohonx.'-'.$xx;
$dd=substr($tarikh_ambil[$x], 0, 2);
$mm=substr($tarikh_ambil[$x], 3, 2);
$yy=substr($tarikh_ambil[$x], 6, 4);
$tarikh_ambil[$x] = $yy."-".$mm."-".$dd;
if($tarikh_ambil[$x] == '--') { $tarikh_ambil[$x] = '0000-00-00'; }
$pdo->exec("insert into simka_spesimen(IDMohon,SubIDMohon, Nama, LainLain, TarikhAmbil, TarikhHantar, TarikhMakmalTerima)
values ('".$IDMohonx."','".$SubIDMohon."','".$spesimen[$x]."','".$bilangan[$x]."','".$tarikh_ambil[$x]."','".$tarikh_hantar_spesimen."','".$tarikh_terima_spesimen."')");
}

I would recommend to wrap your fields into an common name, so that you can run a foreach over each 'fieldset' and then access its corresponding fields, instead of having them separate and independent as you have them now.
HTML would be something like this: (Implement the counter as you wish, but be sure to increment it before adding another set)
<div class='field'>
<div class='checkboxes'>
<div class='checkbox'>
<label><input type='checkbox' id='spesimen$i' name='fieldset[$counter][spesimen]' value='$JenisSpesimen' required minlength='1'/>$JenisSpesimen</label>
</div>
<div class='select'>
<select id='bilangan$i' name='fieldset[$counter][bilangan]' class='med' style='display:none;'>
<option></option>
<option value='Pertama'>Pertama</option>
<option value='Kedua'>Kedua</option>
</select>
</div>
<div class='input' id='tarikh_ambil$i' style='display:none;'>
<input type='text' id='tarikh_ambil_spesimen$i' name='fieldset[$counter][tarikh_ambil_spesimen]' class='small' readonly/>
</div>
</div>
</div>
and your PHP code as follows:
foreach($_POST['fieldset'] as $i=>$fields){
$SubIDMohon = $IDMohonx .'-' . ($i + 1) ;
//If specimen is checked, the value comes with post, otherwise set it to default ''
$specimen = ( isset($fields['specimen']) ) ? $fields['specimen'] : '';
//check if the date is valid format
$date = '';
if(preg_match('^([0-9]{2}-){2}[0-9]{4}$', $fields['tarikh_ambil_spesimen'])){
$date = implode('-', array_reverse( explode('-', $fields['tarikh_ambil_spesimen']) ) );
}
else{
$date = '0000-00-00';
}
$pdo->exec(
"insert into simka_spesimen(IDMohon,SubIDMohon, Nama, LainLain, TarikhAmbil, TarikhHantar, TarikhMakmalTerima)
values (
'" . $IDMohonx . "',
'" . $SubIDMohon . "',
'" . $spesimen . "',
'" . $fields['bilangan'] . "',
'" . $date . "',
'" . $tarikh_hantar_spesimen . "',
'" . $tarikh_terima_spesimen . "'
)"
);
}
Try doing a print_r to your $_POST so you can see how it is structured.
Good luck!
