Post Not Capturing Checkbox Response - php

Question

I have a form with a group of checkboxes that when I post to the database, the responses are not being captured. Error reporting is not showing anything and the field is blank.
The odd thing I find is that I have a second checkbox group setup exactly the same that does post.
The database field is:
name: LAB_Results
type: text
My form group is:
<div class="form-row">
<div class="col-lg-4 mb-2">
<label > 3. LABORATORY RESULTS: within the past 6 months (please submit the results)</label>
</div>
<div class="col-lg-8 mb-2">
<ul class="list-group list-group-flush">
<li class="list-group-item">
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" id="LAB_Results[]" name="LAB_Results[]" value="Chemistry Profile">
<label class="form-check-label" >Chemistry Profile</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" name="LAB_Results[]" id="Lab_Results[]" value="CBC">
<label class="form-check-label" >Complete Blood Count</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" name="LAB_Results[]" id="Lab_Results[]" value="Urinalysis">
<label class="form-check-label" >Urinalysis</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" name="LAB_Results[]" id="Lab_Results[]" value="Urine Culture & Susceptibility">
<label class="form-check-label" >Urine Culture & Susceptibility</label>
</div>
<div class="form-check form-check-inline">
<input class="form-check-input" type="checkbox" name="LAB_Results[]" id="Lab_Results[]" value="Skin Bacterial Culture & Susceptibility">
<label class="form-check-label" >Skin Bacterial Culture & Susceptibility</label>
</div>
<div class="form-check form-check-inline">
<label class="form-check-label" >Other Test(s)</label>
<input class="form-check-input" type="text" id="Lab_Results[]" name="LAB_Results[]" placeholder="Other Test(s)">
</div>
</li>
</ul>

Answer 1

I would remove the square brackets on the field name. Probably you are receiving your data in the $_POST['LAB_Results[]'] variable.
As said #noid you must avoid duplicated ids.
Copied from the comments.
Please remove the last field, the text input named Lab_Results, the Other tests one. Probably you will have to deal with that field separately from the checkboxes.
