I viewed so many post aboit this but still cant get my code to work.
I want to get a php array of my checked checkboxes values.
heres my code:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.2.0/jquery.min.js"></script>
<title>Untitled Document</title>
</head>
<body>
<?php
echo'<form method="post">
<input type="checkbox" name="cim" value="valami">';
echo'<input type="checkbox" name="cim" value="valami2">';
echo'<input type="checkbox" name="cim" value="valami3">';
echo'<input type="checkbox" name="cim" value="valami4">
<input type="submit" value="Felvisz" name="feladat"></form>';
if (isset($_POST['feladat'])) {
?>
<script type="text/javascript">
var checkedValue = $('.messageCheckbox:checked').val();
var myJSON = JSON.stringify(checkedValue);
$.ajax({
type: "POST",
url: "proba.php",
data: { tomb : myJSON },
success: function(){
alert("OK");
}
});
</script>
<?php
var_dump($_POST);
$array = json_decode(stripslashes($_POST['tomb']));
foreach($array as $arr){
echo $arr;
}
}
?>
</body>
</html>
Massages i got: Notice: Undefined index: tomb in D:\programok\xamp\htdocs\SZAKDOGA\Dropbox\proba.php on line 48
Warning: Invalid argument supplied for foreach() in D:\programok\xamp\htdocs\SZAKDOGA\Dropbox\proba.php on line 49

To get an array , you must convert the name to accept multiple so change the input's :
name="cim"
to
name="cim[]"
Also your jquery ajax function should be this :
<script type="text/javascript">
$(function(){
$("form").on("submit",function(e){
e.preventDefault();
var checkedValue = $(this).serialize();
$.ajax({
type: "POST",
url: "proba.php",
data: checkedValue,
success: function(){
alert("OK");
}
});//end ajax
});//end form submit
});
</script>
in php the cim will be the array example
var_dump($_POST["cim"]);
hope it helps

currently, you are testing for checked boxes with class messageChecked. assign your checkboxes that class, give your form an id, then test for checked condition on each checkbox,
$('#yourForm').each(function() {
if($('.messageChecked').is(':checked')) {
checkedValue.push($('.messageChecked:checked').val());
}
}
now send it to your php script via ajax,
$.ajax({
type: "POST",
url: "proba.php",
data: { tomb : (checkedValue) },
success: function(){
alert("OK");
}
});
if done like this you can remove json_decode and stripslashes from your $_POST statement
json_decodeis unnecessary here. ajax will send data as an array object. to get only the values of "checked" checkboxes you need to test them. you currently don't have the class you're testing the checkboxes with assigned to any of the boxes
