Send two variables to js via php

Question

I have

$userPostsInt = array("22", "45", "56");

I am receiving via ajax an id:

$post_id = $_POST['id'];

Then on front end I click and send an ID and I need to check if:

 1. the clicked ID is in the array
 2. if the array count is <= 2 if not do something

So I try:

$totSaved = array();
$userPostsInt = array("22", "45", "56");
$count = count($userPostsInt);
if($count<2) {
  foreach($userPostsInt as $key=>$post){ 
    if( $post == $post_id ) { 
      foreach($userPostsInt as $idInt){ 
        array_push($totSaved, $idInt);
      }
      echo json_encode($count);
    }
  }
} else {
  echo json_encode($count); 
}

Then on ajax success I do:

success: function(data) {
    var received = true;
    if(received) {
        if(data < 2) {
            do_something
        } else {
            do_something
        }
    } else {
        do_something else
    }
}

How can I send 2 variable on echo json_encode($count); in order to do a double check for "is ID in the array? Is the array less than 2?" or is it there another way I'm missing?

Answer 1

the simple way to do is use in_array() along with array output:

$totSaved = array();
$userPostsInt = array("22", "45", "56");
$count = count($userPostsInt);

if(in_array($post_id,$userPostsInt)){
    echo json_encode(array('found'=>'yes','count'=>$count)); 
}else{
    $totSaved[] = $post_id;//add new value for next time checks
    echo json_encode(array('found'=>'no','count'=>$count)); 
}
