Form handling PHP PDO - php

Question

I'm playing around with a form trying to learn PDO.
The problem is that nothing is submitted. Nothing is saved and I don´t receive any errors.
I have a class (ABB). In that class I have a function called "spara_abb" (along with several functions used in the script).
Questions:
Is there any way to complete this code to work?
Is this the right way to solve this?
Any suggestions?
The form:
<?php
if (isset($_POST["submit"])){
$save_abb = $abb->spara_abb($_POST['ident']);
}
?>
<!-- FORM START - Create new ABB -->
<form action="abb_ny.php?amne_id=<?php echo $_GET['amne_id']; ?>&abb_arskurs=<?php echo $_GET['abb_arskurs']; ?>" method="post" enctype="multipart/form-data" id="sky-form1" class="sky-form">
<input type='Hidden' name='lid' value='<? echo $_SESSION['lid']; ?>'>
<input type='Hidden' name='datum' value='<? echo date('Y-m-d'); ?>'>
<input type='Hidden' name='ident' value='<? echo $abb->skapa_ident($_GET['amne_id']); ?>'>
<input type='Hidden' name='amne_id' value='<? echo $_GET['amne_id']; ?>'>
<input type='Hidden' name='arskurs' value='<? echo $_GET['abb_arskurs']; ?>'>
<input type='Hidden' name='aktiv' value='1'>
<header>Skapa ny ABB</header>

Answer 1

You can add all the form variables inside of an array and send it to the function like this:
$array = Array(':ident' => array($_POST['ident'], PDO::PARAM_INT),
':lid' => array($_POST['lid'], PDO::PARAM_INT),
':datum' => array($_POST['datum'], PDO::PARAM_STR),
':amne_id' => array($_POST['amne_id'], PDO::PARAM_INT));
$save_abb = $abb->spara_abb($array);
Now in class you could do something like this:
# Save ABB
public function spara_abb($array) {
// Does IDENT exist?
$abb_existerar = $this->abb_existerar($array);
try{
if ($abb_existerar === true){
$query2 = $this->db->prepare("
UPDATE `abb` SET `arbetsomrade` = :arbetsomrade,`syfte` = :syfte,
`overgripande_mal` = :overgripande_mal, `undervisning` = :undervisning,
`redovisningsform` = :redovisningsform, `lid` = :lid, `datum` = :datum,
`aktiv` = :aktiv
WHERE (`ident`=:ident)");
foreach($array as $key => $val){
$query2->bindParam($key,$val[0],$val[1]);
}
$query2->execute();
....
....
That way you pass all the variables to the class. I would recommend to make sure that all the variables exist with the function isset(), for example:
$idnent = isset($_POST['ident'])? $_POST['ident'] : '';
edit: Use var_dump($array);
to print all the array and see if this is what you wanted.
