Variables on PHP explode set to 1 character? - php

Question

I am trying to post 3 variables via a Checkbox.
If a user ticks a Checkbox for each product, I am trying to send 3 variables:
<input type="checkbox" name="product[]" value="'. $rowAttr["reference"] .'-'. $rowAttr["price"] .'-'. $rowProd["unity"] .'">
The variables are definitely set as I have printed them all to the page where the user can see what Product they are selecting. However, when they submit the form, the variables from the checkbox are set to 1 characters? Where is this going wrong?
$selected = explode('-', $product);
$reference = $selected[0];
$price = $selected[1];
$unity = $selected[2];
echo '<table class="table table-striped">';
echo '<th>Product Reference</th><th>Price</th><th>Unit</th>';
if(isset($_POST['product'])) {
foreach($_POST['product'] as $product) {
print '<tr>';
print '<td>'. $product['reference'] .'</td>';
print '<td>'. $product['price'] .'</td>';
print '<td>'. $product['unity'] .'</td>';
print '</tr>';
}
}
echo '</table>';

Answer 1

try to run the code below
$product = $_POST['product'];
echo "<pre>";
var_dump($product);
echo "</pre>";
I think your array look like this
array(3){
[0]=>array(3) {[0]=>"some value",[1]=>"some value",[2]=>"some value",}
[1]=>array(3) {[0]=>"some value",[1]=>"some value",[2]=>"some value",}
[2]=>array(3) {[0]=>"some value",[1]=>"some value",[2]=>"some value",}
}
So do foreah or call $product[0][1], $product[0][2], $product[0][3]
instead.
