Keep checkbox checked after form submit

Rather than hard-coding your "checked" attribute into each of your <input type="checkbox"> fields, you should be using PHP to determine if the GET variable associated with each field was passed to the script. In that case, you want to append the checked attribute to your <input> field. You can accomplish this by using a ternary operator right inside the field, as such:

<input type='checkbox' name='cities[]' value='CHI' <?= (in_array('CHI', $places)) ? 'checked' : ''; ?> >CHICAGO
<input type='checkbox' name='cities[]' value='DET' <?= (in_array('DET', $places)) ? 'checked' : ''; ?> >DETROIT
<input type='checkbox' name='cities[]' value='LA' <?= (in_array('LA', $places)) ? 'checked' : ''; ?> >LAS ANGELES
<input type='checkbox' name='cities[]' value='NYC' <?= (in_array('NYC', $places)) ? 'checked' : ''; ?> >NEW YORK
<input type='checkbox' name='cities[]' value='DALLAS' <?= (in_array('DALLAS', $places)) ? 'checked' : ''; ?> >DALLAS
<input type='checkbox' name='cities[]' value='SPR' <?= (in_array('SPR', $places)) ? 'checked' : ''; ?> >SPRINGFIELD
<input type='checkbox' name='cities[]' value='PHI' <?= (in_array('PHI', $places)) ? 'checked' : ''; ?> >PHILIDELPHIA

Checkbox Php : Keep checked only the checked checkbox after submitting Get form

The problem is because of this line,

<?php if (isset($_GET['category'])) echo "checked='checked'"; ?>> ...
         ^^^^^^^^^^^^^^^^^^^^^^^^^^

Upon form submission $_GET['category'] will be set, hence this condition isset($_GET['category']) will hold true for all the checkboxes. And that's why all the checkboxes are checked irrespective of which one you checked earlier. So your foreach loop should be like this:

<?php foreach ($categories as $cat) {  ?>
    <li>
    <input id="category" name="category[]"  type="checkbox" value="<?= $cat->term_id; ?>" 
    <?php if (isset($_GET['category']) && in_array($cat->term_id, $_GET['category'])) { echo "checked='checked'"; } ?>><?= $cat->name ?></input>
    </li>
<?php } ?>
