Merge Two Array

[nitediver]

I have load data from two different table "prod & size", in push.php all data from chosen product push into array.
My question is, how to push the data from "size" along with the "prod"?
I wonder if I merge those two arrays.

Prod.php

<table>
<tr>
<td style="vertical-align:top;">
<img src="<? echo $qprod['prod_img'] ?>">
</td>
<td>
<pre>
<? echo $qprod['prod_name'] ?><br />
Rp. <? echo $harga ?><br />
<? echo $qprod['prod_vendor'] ?><br />
<? echo $qprod['prod_desc'] ?><br />
<?
$qsize = mysql_query("SELECT * FROM a_size ORDER BY size_id ASC")or die("Error Select Size");
echo "Select Size : <select name=\"size_id\">";
while($rsize=mysql_fetch_array($qsize))
{
echo ("
<option value=$rsize[size_id]>$rsize[size_number]</option>
");
}
echo "</select>";
?>
</pre>
<center><a href="z_push.php?prod_id=<?=$qprod['prod_id']?>&action=add">Add To Cart</a></center>
</td>
</tr>
</table>

Push.php

<?
include "function.php";
connect();
session_start();

$prod_id = $_GET['prod_id'];
$action = $_GET['action'];

switch($action){
	case "add":
	$_SESSION['cart'][$prod_id]++;
	break;
	case "remove":
	$_SESSION['cart'][$prod_id]--;
	break;
	case "empty":
	break;
}
header("location:z_cart.php");
?>

Cart.php

<?
$prod_id = $_GET['prod_id'];

if(!$_SESSION['cart'])
{
	echo "Cart Empty!";
}else{
	foreach($_SESSION['cart'] as $prod_id => $q)
	{
	$prod = mysql_query("SELECT prod_name,prod_price FROM a_prod WHERE prod_id='$prod_id'");
		if(mysql_num_rows($prod) > 0)
		{
		list($prod_name, $prod_price) = mysql_fetch_row($prod);
		$subtotal = $prod_price * $q;
		$total += $subtotal;
		echo $prod_name." - ".$q." - $".$subtotal."<br>";
		}
	}
	echo "<br>Total : $".$total;
}
?>

array_merge() would seem to be what you need.

Use post?

<?php 

// I would not use get method for product only for action and then the action in 
// form action=""

if(isset($_POST)&&!empty($_POST['input_add']) {
 $_SESSION['cart'][$_POST['input_size']];
 $_SESSION['cart'][$_POST['input_prodid']];
}
# ex.

# HOME -> PICK PRODUCTS -> Size && Product  -> PROCESS -> CHECK OUT

<form method="post" action="<?php $_SERVER['PHP_SELF']; ?>">
<select name="select_size">
<?php $set = mysql_query("sql"); while($row = mysql_fetch_assoc($set) { ?>
 <option value="<?php echo $row['size']; ?>">
<?php echo $row['size']; ?>
</option>
<?php } // close while ?>
</select>
<input type="hidden" value="<?php print $qprod['prod_id']; ?>" name="input_prodid" />
<input name="input_add" value="Add"  type="submit" />
</form>

?>

dont use short tags
<?
they are deprecated

use <?php

short tags will give you problems sooner rather than later

&& <?= ~ also if the <? not enabled in php.ini will have to re do all the tags

@,rincewind456
thanks a lot, Im new in php.

@
I forgot using form,

So on the push.php it will goes like this?
tell me if im wrong.

<?php

$prod_id = $_GET['prod_id'];
$size_id = $_GET['size_id'];

$action = $_GET['action'];

//Is it goes like this,

switch($action){
    case "add":
    $_SESSION['cart'][$prod_id]++;
    $_SESSION['cart'][$size_id]++;
    break;

//Or like these?

switch($action){
    case "add":
    $_SESSION['cart'][$prod_id][$size_id]++;
    break;
}

?>

<?php
// I post to the same page only activate the code that is needed
// if you want to use the get method instead of post to send the data
// to push, your get method data will be shown in the url
// which is unsafe since a user can edit the url and put his own data
// therefore send the data via post method and recieve it in $_POST variable
// on push.php

// also i dont use switch I use if, elseif, else statements.



// now to save in session the variables from $_POST variable array
if(isset($_POST)) {

if(isset($_POST['input_prod_id'])) { $prod_id = $_POST['input_prod_id']; } // the name of input in your form that contains prodid
if(isset($_POST['input_size_id'])) { $size_id = $_POST['input_size_id']; } // the name of input in your form that contains sizeid
// now $_POST variable will contain both variables you need to run your mysql query
// therefore you do not need an $action since you specify the action in <form action=""

// $action = $_GET['action'];

$_SESSION['cart'][$prod_id]++;
$_SESSION['cart'][$size_id]++;
   header("Location: http://localhost/cart.php");
exit;

}

?>

My code use,

<a href="z_push.php?prod_id=<?=$qprod['prod_id']?>&action=add">Add To Cart</a>

for move to the second page, in your code I dont see any code to move/redirect to second page, or you just using one page?

$_SERVER['PHP_SELF'];

Im using $PHP_SELF, is it deprecated?

Yes; everything that requires turning on [man]register_globals[/man] is deprecated, and will be going away in PHP 6.

[nitediver]

thanks,
anyone please answer my question above.

[cretaceous]

which question is not answered ?!

it looks as if you are using
$prod_id = $_GET['prod_id'];

but your form method is 'post' and you wont receive the values

you should be using
$prod_id = $_POST['prod_id'];
