附加元素未显示CSS ISSUE JAVASCRIPT PHP

Question

I have experiencing some problems with fetching the grandchilds from my db table: referrals . However, it seems that my code can actually fetch the usernamee of my grandchilds . But it is not appearing below my child's line and there is no error in INSPECT .

Please see the OUTPUT image I attached here: Attached here are the images of the output of my code:

This is the UPDATED database table name referrals:

I used Javascript to fetch the data's inside "referrals" table

<!-- GENEOLOGY TREE -->
    <div class="tree">
       <?php $id = 1; ?>
          <ul>
             <li>
               <div id="parent_account"><a href="#"><img src="user.png" alt="Avatar" style="width:50px"/></br>Parent<?php echo $id; ?></a></div>
             </li>
        </ul>
      </div>
<!-- END OF GENOLOFY TREE -->


  <script>
$(document).ready(function(){
    // start get children
    var _id = "<?php echo $id ?>";
    var child = "";
    var child_id = [];
    var gchild_id = [];
    var count = 0;

    $.post('get_child_referrals.php', { id:_id }).done(function(response){
        var response = jQuery.parseJSON(response);
        var referred = response["referred"];
        var referred_len = response["referred"].length;
        if(referred_len > 0){
            child += "<ul>";
            for(var x = 0; x < referred_len; x++) {
                console.log(referred[x]["usernamee"]);
                count += 1;
                child_id[x] = referred[x]["id"];
                child += "<li id='child"+x+"'><a href="+x+"><img src='user.png' alt='Avatar' style='width:50px'/><br>Child "+referred[x]["usernamee"]+"</a></li>";
            }
            child += "</ul>";
            console.log(child);

get_child_referrals.php

include('connectdb.php');
$response = array();
$response["referred"] = array();
$id = $_POST['id'];
$sql = "SELECT * FROM referrals WHERE referral_id='$id'"; // MY RECRUITERS
$result = $conn->query($sql);
while($data = $result->fetch_assoc()) {
                array_push($response["referred"], $data);
}
echo json_encode($response);

For more info, this is my logs on my inspect console:

Answer 1

First,Inspect for the username.Check if its coming in HTML.Sometimes, it is rendered but hidden.Secondly, just just console the child element,to confirm you are appending it to the right one.

console.log($(child));

I tried your code in my local, and got an output as in the pic.Check if its something that you want to get.

Answer 2

So looking at your console, this line console.log($("#child"+i).length); appears to be returning 0 which would mean that the element in question doesn't seem to exist.

Can you log this without the .length and make sure that it is still getting the right element.
