POST $_SESSION variable using HTML - php

Question

hope you are all doing well. I'm not too sure on how I worded the title so I'm sorry for that.
I have this code:
<form method="POST" action="checkoutManager.php" name="submitOrder">
<?php
if(isset($_SESSION["cart_item"])) {
$item_total = 0;
$total;
foreach ($_SESSION["cart_item"] as $item) {
$item_total += (($item["price"]-$item["discount"])*$item["quantity"]);
$total = $total + $item_total;
?>
<tr>
<td class="product-name">
<?php echo $item["name"]; ?> <strong class="product-qty"> × <?php echo $item["quantity"]; ?></strong>
</td>
<td class="product-total">
<span class="amount"><?php echo "$".$item_total; ?></span>
</td>
</tr>
<?php
$item_total = 0;
}
}
?>
<input type="submit" name="btnSubmitOrder" value="Submit Order">
</form>
How would I go about submitting all the $_SESSION items in using form tag. I have tried submitting as an array but failed. All help appreciated. Thanks in advance

Answer 1

why don't you create hidden elements like
<input type="hidden" name="total" value="<?php echo $total; ?>">
and anything you need use hidden input field and you can access them after the submit button is clicked by using $_POST in your checkoutManager.php
UPDATE
simply you can process all the fields in checkoutManager.php using session, you dont need any form to be submitted. create a link to checkoutManager.php and do all the calculations there

Answer 2

Try below code.
In this code I have added one hideen count field.
By using count u can use for loop after submit.
I display only one input for name but u can add multiple inputs inside for loop of form.
I also concated $i variables, so all input names are different as name1, name2,... U can use it on submit as $_POST['name'.$i] after submit.
<form method="POST" action="checkoutManager.php" name="submitOrder">
<?php
<input type="hidden" name="count" value="<?php echo count($_SESSION["cart_item"]); ?>">
$i=0;
foreach ($_SESSION["cart_item"] as $item)
{
?>
<input type="text" name="input_name<?php echo $i; ?>" value="<?php echo $item['name']; ?>" />
<?php
$i++;
}
?>
<input type="submit" name="btnSubmitOrder" value="Submit Order">
</form>

Answer 3

You need to add input fields in foreach loop for all your items that are coming in $_SESSION["cart_item"]. After submission, you need to use foreach again for inserting all your items in your temp table one by one.
Update your code like below:
<form method="POST" action="checkoutManager.php" name="submitOrder">
<?php
if(isset($_SESSION["cart_item"])) {
$item_total = 0;
$total = 0;
foreach ($_SESSION["cart_item"] as $item) {
$item_total +=
(($item["price"]-$item["discount"])*$item["quantity"]);
$total = $total + $item_total;
?>
<input type="hidden" name="price[]" value="<?php echo $item["price"]; ?>">
<input type="hidden" name="name[]" value="<?php echo $item["name"]; ?>">
<input type="hidden" name="discount[]" value="<?php echo
$item["discount"]; ?>">
<input type="hidden" name="quantity[]" value="<?php echo
$item["quantity"]; ?>">
<tr>
<td class="product-name">
<?php echo $item["name"]; ?> <strong class="product-qty"> × <?php
echo $item["quantity"]; ?></strong>
</td>
<td class="product-total">
<span class="amount"><?php echo "$".$item_total; ?></span>
</td>
</tr>
<?php
$item_total = 0;
}
}
?>
<input type="submit" name="btnSubmitOrder" value="Submit Order">
</form>
And you can access all your input fields after submission in the below way.
foreach($_POST['name'] as $key => $val){
echo $_POST['name'][$key];
echo $_POST['price'][$key];
echo $_POST['discount'][$key];
echo $_POST['quantity'][$key];
}
Hope it helps!
