HTML形式的数组仅在使用var_dump（）进行检查时产生第一个结果

Question

Here is the HTML and jQuery that produces the form (all it does is allows users to create another input field that has the same names: skillName[] and skillLevel[]):

$(document).ready(function() {
  var max_fields = 100;
  var wrapper = $(".wrapper");
  var add_button = $(".new-skill-field");

  var i = 1;
  $(document).on("click", ".new-skill-field", function(e) {

    e.preventDefault();
    if (i < max_fields) {
      i++;
      $(wrapper).append('<div><label>Skill Name:</label><input type="text" name="skillName[]"><label>Skill Level:</label><input type="text" name="skillLevel[]" class="input-small"><button class="remove-skill">Remove This Skill</button><br></div>');
    }
  });

  $(wrapper).on("click", ".remove-skill", function(e) {
    e.preventDefault();
    $(this).parent('div').remove();
    i--;
  });
});

<script src="//code.jquery.com/jquery-3.1.1.min.js"></script>

<div class="wrapper">
  <div>
    <label>Skill Name:</label>
    <input type="text" name="skillName[]" id="skillName">
    <label>Skill Level:</label>
    <input type="text" name="skillLevel[]" id="skillLevel" class="input-small">
    <br>
  </div>
</div>
<button class="new-skill-field">Add Another Skill</button>

Regardless of how many fields I create and enter values into, if my PHP script is nothing else but var_dump($_POST['skillName']), it only returns one value: the first input field. I know this works, as I have done this in the past. I just cannot figure out why this form, or perhaps this jQuery, is causing it to only pass one value in the array.

And yes, I do need the arrays to be coded in the form... there is no other way of passing the array to my class and have it do what I need it to.

Okay this is one of the weirdest things that has happened in my (albeit short) programming career... I didn't touch anything whatsoever in the code, I refreshed the page to check the HTTP Live Headers since I had cleared them. It randomly picked up the array, after refreshing the same code (on 3 different browsers on this computer, 2 on my MacBook, and on my phone). I honestly have no idea what is going on at this point, but it seems to be working... for now. Thanks for taking the time to try and help!

Here's to hoping the problem doesn't arise again, because I have no clue what changed to cause it to pick up the array indices!
