Hello overflowers!
The problem i'm stuck on at the moment is following.
I have managed to add a "✓" to selected users.
I have added a "data-id" attribute to each listed user.
The thing I'm trying to figure out is how I have post the users data-id from jquery to my php page.
Jquery:
task_takers = [];
var i = 0;
$(".new-task-takers ul.select_takers li").each(function(){
$(this).click(function(){
$(this).toggleClass("active");
if($(this).find('.fa').length > 0){
$(this).find('.fa').remove();
}else{
$('<i class="fa fa-check" aria-hidden="true"></i>').insertBefore($(this).find("div"));
}
console.log("Selected:", $(this).data("id"));
i += 1;
task_takers[i] = $(this).data("id");
console.log(task_takers);
console.log(i);
});
});
console.log(task_takers);
PHP:
$task_takers = isset($_POST['task_takers']) ? $_POST['task_takers'] : NULL;
var_dump($task_takers);
All I'm getting is a NULL
Edit:
I got it too work, but the thing is the array is getting flooded if you select the user and un-select and re-select.
Array:
[1: 2, 2: 3, 3: 3, 4: 3, 5: 3, 6: 3]
As you can see it spams ID: 3

You have to send data to the php script in order to make it work.
Here is a little example of jQuery.ajax from the docs :
$.ajax({
method: "POST",
url: "some.php",
data: { name: "John", location: "Boston" }
})
.done(function( msg ) {
alert( "Data Saved: " + msg );
});
I usually use it as following :
$("form").submit(function(){
$.ajax({
type: 'POST',
url: "/relative/path/to/php/script.php",
data: $("form").serialize(),
success: function(data) {
console.log(data)
},
error: function(jqXHR, textStatus, errorThrown) {
console.log(textStatus, errorThrown);
}
});
});
Hope it helps.
EDIT
Since your last edit :
You could solve this by using array_unique to remove duplicated items of the array from the PHP script.
For example :
php > $arr = array("1" => 2, "2" => 3, "3" => 3, "4" => 3, "5" => 3, "6" => 3);
php > print_r($arr);
Array
(
[1] => 2
[2] => 3
[3] => 3
[4] => 3
[5] => 3
[6] => 3
)
php > $uniq_arr = array_unique($arr);
php > print_r($uniq_arr);
Array
(
[1] => 2
[2] => 3
)
