"add to cart" button works on localhost but not on cpanel (using sessions)

I have contacted godaddy and everything looks good on their end. This code works on my localhost when using xampp but not when uploaded on cpanel. MYSQL works. I am using sessions only to make the "add to cart" button work. When I click the button it refreshes but doesn't add anything to cart. Do I also have to use cookies? If I do then how can I add it to this code?
<?php
session_start();
$connect = mysqli_connect( "localhost", "username", "pass", "");
if(isset($_POST["add_to_cart"]))
{
if(isset($_SESSION["shopping_cart"]))
{
$item_array_id = array_column($_SESSION["shopping_cart"], "item_id");
if(!in_array($_GET["id"], $item_array_id))
{
$count = count($_SESSION["shopping_cart"]);
$item_array = array(
'item_id' => $_GET["id"],
'item_name' => $_POST["hidden_name"],
'item_price' => $_POST["hidden_price"],
'item_quantity' => $_POST["quantity"]
);
$_SESSION["shopping_cart"][$count] = $item_array;
}
else
{
echo '<script>alert("Item Already Added")</script>';
}
}
else
{
$item_array = array(
'item_id' => $_GET["id"],
'item_name' => $_POST["hidden_name"],
'item_price' => $_POST["hidden_price"],
'item_quantity' => $_POST["quantity"]
);
$_SESSION["shopping_cart"][0] = $item_array;
}
}
if(isset($_GET["action"]))
{
if($_GET["action"] == "delete")
{
foreach($_SESSION["shopping_cart"] as $keys => $values)
{
if($values["item_id"] == $_GET["id"])
{
unset($_SESSION["shopping_cart"][$keys]);
echo '<script>alert("Item Removed")</script>';
echo '<script>window.location="mysqlcart.php"</script>';
}
}
}
}
?>
<?php
if(!empty($_SESSION["shopping_cart"]))
{
$total = 0;
$return = [];
foreach($_SESSION["shopping_cart"] as $keys => $values) {
?>

</tr>
<?php
$total = $total + ($values["item_quantity"] * $values["item_price"]);
$return[] = $values["item_quantity"];
$return[] = $values["item_name"];
}
?>
<?php

Changing checkbox to a button to filter wordpress posts

I have just added some code to my archive template in order to filter posts by a custom field using checkboxes...this is all working fine however I would like to have buttons instead of checkboxes so I'm wondering if this possible?
This is my code for the post filter:
<div id="search-houses">
<?php
$field = get_field_object('purchase');
$values = isset($_GET['purchase']) ? explode(',', $_GET['purchase']) : array();
?>
<ul>
<?php foreach( $field['choices'] as $choice_value => $choice_label ): ?>
<li>
<input type="checkbox" value="<?php echo $choice_value; ?>" <?php if( in_array($choice_value, $values) ): ?>checked="checked"<?php endif; ?> /> <?php echo $choice_label; ?>
</li>
<?php endforeach; ?>
</ul>
</div>
there is also some javascript to update the url if this is needed?
<script type="text/javascript">
(function($) {
$('#search-houses').on('change', 'input[type="checkbox"]', function(){
// vars
var $ul = $(this).closest('ul'),
vals = [];
$ul.find('input:checked').each(function(){
vals.push( $(this).val() );
});
vals = vals.join(",");
window.location.replace('<?php echo home_url('property'); ?>?purchase=' + vals);
console.log( vals );
});
})(jQuery);

post jquery array to php page when checking checkboxes

<div style="padding-right: 20px" class="row"><label>
<input type="checkbox" value="<?php echo $aa2['name'] ?>" name="checks<?php echo $aa['id'] ?>[]"id="check<?php echo $aa['id']; ?>"><?php echo $aa2['name'] ?>
</label></div>
<?php } ?>
</div>
<a class="btn btn-primary btn-sm" name="update-all"onclick="update_all('prop_id<?php echo $aa['id']; ?><?php $counter; ?>','checks<?php echo $aa['id'] ?>')"id="btn-all<?php echo $aa['id']; ?><?php $counter; ?><?php echo $p['id']; ?>">save</a>
i tried this code but it is not working
<script type="text/javascript">
function update_all(a, b) {
var aa = document.getElementById(a).value;
var values = new Array();
$("input:checkbox[name=b]").each(function () {

}
});
alert(aa);
alert(values.length);
alert(values);
}
</script>

Check if radio button value is, then echo some HTML

I want to check if the value of the select field is some value and if it is, it needs to echo some text.
I use this code for input box in the form:
<li>
<div class="input-box">
<strong><?php echo $this->__('Would you recommend this product to a friend?') ?></strong>
<?php foreach ( $this->getOptions() as $option ): ?>
<label class="recommend">
<input type="radio" name="recommend" id="recommend_field
<?php echo $option['value'] ?>" class="radio-gender" value="
<?php echo $option['value'] ?>"
<?php if ($option['value'] == $value)
echo ' checked="checked"' ?> >
<?php echo $this->__($option['label']) ?></input>
</label>
<?php endforeach ?>
</div>
</li>
And I currently echo the entire value of the input box with this line:
<div id="reviewwriter">
<span class="recommendation">
<?php echo $this->getAnswer() ?>
</span>
</div>
Code is loaded by this php:
public function confRecommendItemsArray()
{
$resArray = array();
if (Mage::getStoreConfig('advancedreviews/recommend_options/recommend_field1')) {
$resArray[] = array(
'value' => 1,
'label' => Mage::getStoreConfig('advancedreviews/recommend_options/recommend_field1')
);
}
if (Mage::getStoreConfig('advancedreviews/recommend_options/recommend_field2')) {
$resArray[] = array(
'value' => 2,
'label' => Mage::getStoreConfig('advancedreviews/recommend_options/recommend_field2')
);
}
And
class AW_AdvancedReviews_Block_Recommend_Field extends Mage_Core_Block_Template
{
public function canShow()
{
return (Mage::helper('advancedreviews')->confShowRecommend()
&& count(Mage::helper('advancedreviews')->confRecommendItemsArray()));
}
public function getOptions()
{
return Mage::helper('advancedreviews')->confRecommendItemsArray();
}
}
The values of the select field are
1. Yes
2. No
I want to check if value is Yes and if so echo 'Value is Yes'.
And if value is No than echo ''.
See also this JSFiddle: http://jsfiddle.net/wL3xu9d7/1/
But I do not know why it is not working.
How can I achieve that?

i hope this solution you want...
<li>
<div class="input-box">
<strong><?php echo $this->__('Would you recommend this product to a friend?') ?></strong>
<?php foreach ( $this->getOptions() as $option ): ?>
<label class="recommend">
<input type="radio" name="recommend" id="recommend_field<?php echo $option['value'] ?>" class="radio-gender" value="<?php echo $option['value'] ?>"<?php if ($option['value'] == $value) echo ' checked="checked"' ?>><?php echo $this->__($option['label']) ?></input>
</label>
<?php endforeach ?>
</div>
</li>
add hidden field on answer
<div id="reviewwriter">
<span class="recommendation" id="reviewwriteranswer">
<?php echo $this->getAnswer() ?>
</span>
</div>
<script>
$$(".radio-gender").each(function(el) {
el.observe("click", function(event) {
if(el.checked)
{
sub = $('reviewwriteranswer').value;
sub ==sub =.trim();
if(el.value==sub)
{
$('reviewwriteranswer').update('value is yes');
}else {
$('reviewwriteranswer').update('value is No');
}
}
});
});
</script>
<scrip>
var allElements = document.body.getElementsByTagName("*");
for(var i = 0; i < allElements.length; i++) {
var text = allElements[i].innerHTML;
text=text.trim();
if (text == 'Yes') {
allElements[i].innerHTML = "Value is Yes";
}
if (text == 'No') {
allElements[i].innerHTML = "Value is No";
}
}
</scrip>
