    Hi,

    I m trying to export a cart script to paypal as a form, for paypal to understand that ive sent multiple items i need to give each product in the array a number starting from one going up in numberical order,

    iv tried to use a for loop with an increment counthing variable for($counter=1;$counter>0;$coutner++) but cant get it to work with this existing code; whats the easiest way to do this?! i know how to get all of the variables and stuff into the form o i would just like to know how to output the array key number (is i?) as a variable where it says in teh code below...

     

    i want the final output to be something like this

                           

    1 ProductA Quantity: 20

    2 ProductB Quantity: 15

    3 ProductC Quantity: 6

     

    this is the point at which i output the cart before proceeding to the checkout,

     

    function writeShoppingCart() {
$cart = $_SESSION['cart'];
if (!$cart) {
	return '<p>You have no items in your shopping cart</p>';
} else {
	// Parse the cart session variable
	$items = explode(',',$cart);
	$s = (count($items) > 1) ? 's':'';
	return '<p>You have <a href="cart.php">'.count($items).' item'.$s.' in your shopping cart</a></p>';
}
}

function showCart() {
global $db;
$cart = $_SESSION['cart'];
if ($cart) {
	$items = explode(',',$cart);
	$contents = array();
	foreach ($items as $item) {
		$contents[$item] = (isset($contents[$item])) ? $contents[$item] + 1 : 1;
	}
	$output[] = '<form action="cart.php?action=update" method="post" id="cart">';
	$output[] = '<table>';
	foreach ($contents as $id=>$qty) {
		$sql = 'SELECT * FROM syn_vinyl_product WHERE prod_id = '.$id;
		$result = $db->query($sql);
		$row = $result->fetch();
		extract($row);
		$output[] = '<tr>';
		$output[] = '<td><a href="cart.php?action=delete&id='.$id.'" class="r">Remove</a></td>';
		$output[] = '<td>'.$prod_title.' by '.$artist.'</td>';
		$output[] = '<td>£'.$price.'</td>';
		$output[] = '<td><input type="text" name="qty'.$id.'" value="'.$qty.'" size="3" maxlength="3" /></td>';
		$output[] = '<td>£'.($price * $qty).' ////////////////ITEM NUMBER HERE /////////////////</td>';
		$total = '';
		$total += $price * $qty;
		$output[] = '</tr>';
	}
	$output[] = '</table>';
	$output[] = '<p>Grand total: <strong>£'.$total.'</strong></p>';
	$output[] = '<div><button type="submit">Update cart</button></div>';
	$output[] = '</form>';
} else {
	$output[] = '<p>You shopping cart is empty.</p>';
}
return join('',$output);
}

    Upload Multiple Imags then Echo absolute URL

    in PHP Coding Help

    Posted

    Hi,

     

    Is it possible to show the absolute UL of the image files uploaded after running this upload script? if so how?

    eg:

     

    http://mysite.com/admin/image1name.jpg

    http://mysite.com/admin/image2name.jpg

    http://mysite.com/admin/image3name.jpg

     

     

    ../admin/form.php:

     

    <form enctype="multipart/form-data" action="upload.php" method="post">
Image1: <input name="userfile[]" type="file" /><br />
Image2: <input name="userfile[]" type="file" /><br />
Image3: <input name="userfile[]" type="file" /><br />
Image4: <input name="userfile[]" type="file" /><br />
<input type="submit" value="Upload" />
</form>

     

    ../admin/Upload .php:

     

    <?php
$success = 0;
$fail = 0;
$uploaddir = '';
for ($i=0;$i<4;$i++)
{
if($_FILES['userfile']['name'][$i])
{
$uploadfile = $uploaddir . basename($_FILES['userfile']['name'][$i]);
$ext = strtolower(substr($uploadfile,strlen($uploadfile)-3,3));
if (preg_match("/(jpg|gif|png|bmp)/",$ext))
{
if (move_uploaded_file($_FILES['userfile']['tmp_name'][$i], $uploadfile)) 
{
$success++;
} 
else 
{
echo "Error Uploading the file. Retry after sometime.\n";
$fail++;
}
}
else
{
$fail++;
}
}
}
echo "<br> Number of files Uploaded:".$success;
echo "<br> Number of files Failed:".$fail;

?>
