Add to Cart

[bullbreed]

Hi Guys

I hava a page on my website that enables a customer to select a product, choose a colour and a size, create some custom text then send that data to my cart.php page. I'm not sure if I am doing this the correct way and havent done a cart before.

This form collects the data then posts it to the cart.php page and echo's it to the screen.

<form action="cart.php" method="POST">

<input type="hidden" name="category" id="category" value="<?php echo $_GET['cid']; ?>" />
<input type="hidden" name="name" id="name" value="<?php echo $_GET['nid']; ?>" />
<input type="hidden" name="colour" id="colour" value="<?php echo $_GET['colid']; ?>"  />
<input type="hidden" name="input" id="input" value="<?php echo $_POST['input']; ?>"  />
<input type="hidden" name="fontselect" id="fontselect" value="<?php echo $_POST['fontselect']; ?>"  />
<input type="hidden" name="sizeselect" id="sizeselect" value="<?php echo $_POST['sizeselect']; ?>"  />

<div class="textinputgo"><input name="cart" type="submit" id="cart" value="Add to Cart" /></div>

</form>

This is the cart.php page which displays the product selections on the page;
( I have used tables for now but will change these to divs.)

<h1>Shopping Cart</h1>
<?php

$submit = ($_POST['cart']);

if (!isset($submit)){
echo 'Your cart is empty';
}else {

//Form data
$category = ($_POST['category']);
$name = ($_POST['name']);
$colour = ($_POST['colour']);
$text = ($_POST['input']);
$font = ($_POST['fontselect']);
$size = ($_POST['sizeselect']);

if (isset($submit)){

// This page displays the contents of the shopping cart.

    // Create a table and a form.
echo '<table border="1" border color="#ff9999" width="90%" cellspacing="3" cellpadding="3" align="left">

    <tr>
            <td align="left" width="15%"><b>Category</b></td>
            <td align="left" width="15%"><b>Name</b></td>
            <td align="left" width="15%"><b>Colour</b></td>
            <td align="left" width="15%"><b>Text</b></td>
            <td align="left" width="10%"><b>Font</b></td>
            <td align="left" width="15%"><b>Size</b></td>
    </tr>
';

echo '<tr>';
echo '<td align="left">' . $category . '</td>';
echo '<td align="left">' . $name . '</td>';
echo '<td align="left">' . $colour . '</td>';
echo '<td align="left">' . $text . '</td>';
echo '<td align="left">' . $font . '</td>';
echo '<td align="left">' . $size . '</td>';
echo '</tr>';

echo '</table>';
}
}

?>

My questions are;

1. How do I add the facility to increse the quantity of the products on the cart.php page?

2. If I go to another page then click on cart again the cart is empty so how do I keep the info in the cart? I'm assuming some sort of session but dont know how to do these.

Thanks guyz

any reason not to use one of the many shopping carts\whole shopping sites pre-made scripts out there?

[bullbreed]

Yes, because;

1, I dont like them. They do way to much than needed
2, I'm learning php and mysql by developing a CMS and Shopping Cart

well ok then, store the cart in a db, the user needs to be tracked with a session, and put the session id in the db with the cart contents. When dealing with money (shopping site) make sure you know about security.
