    [SOLVED] Looping around to recordsets

    in PHP Coding Help

    Posted

    Hi everyone,

     

    Got a problem involving looping around 2 sets of records at the same time and comparing them. Basically I have 2 tables:

    size_ref

    size_id

    size

     

    garment_sizes

    product_id

    size_id

     

    At the moment I loop around 'size_ref' to create a number of checkboxes. I want to loop compare the two recordsets to "check" the checkbox if the value in 'garment_sizes' matches the value in 'size_ref' (they are linked on 'size_id'). I have some code below but it is does not currently work, as I have been playing around with it to try and get this to work: -

     

    <?php
$querysize = "SELECT * FROM size_ref ORDER BY size_id";
$resultsize = mysql_query($querysize);
f ($resultsize){
} else {
echo "Error connecting to database. Please contact the administrator of the site.";
exit();
}

$querygs = "SELECT DISTINCT size_id FROM garment_sizes WHERE product_id = $pid ORDER BY size_id";
echo $querygs;
$resultgs = mysql_query($querygs);
if ($resultgs){
} else {
echo "Error connecting to database. Please contact the administrator of the site.";
exit();
}

$i =1;
echo "<i>(More than one can be selected)</i><table border=\"0\"><tr>";

while ($size = mysql_fetch_array ($resultsize, MYSQL_ASSOC)) {
$sizeid = $size['size_id'];
$sizename = $size['size'];
$check = "";

//I had another loop that went around garment_sizes and checked here, but deleted it as it didnt work. It simply repeated every record. 

if ($i == 2) {
echo "<td><input type=\"checkbox\" value=\"$sizeid\" name=\"size[]\" $check> $sizename</td></tr>\n";
$i =1;
} else {
echo "<td><input type=\"checkbox\" value=\"$sizeid\" name=\"size[]\" $check> $sizename</td>\n";
$i = $i + 1;
}

//The loop ended here

}
echo "<td> </td></tr></table>";
mysql_free_result($resultsize);
mysql_free_result($resultgs);		  
?>

     

    Please disregard the fact I have no connection etc as this is all done further up the page. Help would be much appreciated.

    SESSION variables...again

    in PHP Coding Help

    Posted

    Hey, posted something a few days, thought I had fixed it but how little I know. Anyway I am storing information about a shopping basket in a session array. It seemed to work fine on my local machine on apache, but as soon as it was loaded to the server they seem to behave very irratically i.e disappear/reappear when deleted or quantites change. Has anything similar happened to anyone else. Help would be appreciated. Code is below: -

     

    Cheers

    SESSION variables for a newbie

    in PHP Coding Help

    Posted

    Sorry forgot to include that I am starting the session. The variables work. But it is just my understanding of how to place them in an array that will allow me to loop around each product and display the qty, size and colour. At present I am storing by the Product_id, but each prodduct can appear more than once example:

     

    prodocut_id  product      qty      colour

      1                t-shirt        1        red

      1                t-shirt        1        blue

     

    At the moment the colour is replaced evertime as I am sotring it against the product_id. Is there a better way to store it? Forgive me if I am rambling have been trying to solve this for a good few hours. Thanks for your time.

    Hi,

     

    I will post the code below. I wanted to store product_id, colour, size and qty dynamically so I could loop around and populate the shopping basket. Is this possible? Or should I create a mysql table to store the shopping basket information temporarily.

     

    
<?php
if (is_numeric ($_POST['pid'])) {
$pid= $_POST['pid'];
$colour = $_POST['colour'];
$size = $_POST['size'];

//Check cart already contains one of these products
if (isset ($_SESSION['cart'][$pid]['qty'])) {
	$qty = $_SESSION['cart'][$pid]['qty'] + 1;
} else {
	$qty = 1;
}

//Add to the cart session variable
$_SESSION['cart'][$pid]['qty'] = $qty;
$_SESSION['cart'][$pid]['colour'] = $colour;
$_SESSION['cart'][$pid]['size'] = $size;	

}

//Check if the form has been submitted (to update cart).
if (isset ($_POST['submit'])) {
foreach ($_POST['qty'] as $key => $value) {
	if (($value == 0) AND (is_numeric ($value))) {
		unset ($_SESSION['cart'][$key]);
	} elseif (is_numeric($value) AND ($value > 0) ) {
		$_SESSION['cart'][$key]['qty'] = $value;
	}
}
}

//Check if empty
$empty = TRUE;
if (isset ($_SESSION['cart'])) {
foreach ($_SESSION['cart'] as $key => $value) {
	if (isset($value)) {
		$empty = FALSE;
	}
}
}


//Cart not empty
if (!$empty) {

require_once ('includes/config.inc');

require_once('includes/mysql_connect.php');

//Retrieve information
$query = 'SELECT * FROM garments WHERE product_id IN (';
foreach ($_SESSION['cart'] as $key => $value) {
	$query .= $key . ',';
}

$query = substr ($query, 0, -1) . ') ORDER BY style';

$result = mysql_query($query);

//Create table & form
echo '<table border="0" width="100%" cellspacing="3" cellpadding="3">

while ($row = mysql_fetch_array ($result, MYSQL_ASSOC)) {

	//Calculate the total and subtotals.
	$subtotal = $_SESSION['cart'][$row['product_id']]['qty'] * $row['price'];
	$total += $subtotal;

	//Print the row
	echo " <tr>
	<td align=\"left\">{$row['style']}</td>
	<td align=\"left\">{$_SESSION['cart'][$row['product_id']]['colour']}</td>
	<td align=\"left\">{$_SESSION['cart'][$row['product_id']]['size']}</td>
	<td align=\"left\">{$row['price']}</td>
	<td align=\"left\"><input type=\"text\" size=\"3\" name=\"qty[{$row['product_id']}] \" 
	value=\"{$_SESSION['cart'][$row['product_id']]['qty']}\" /></td>
	<td align=\"left\">£" . number_format($subtotal, 2) . "</td></tr>\n";

} //end while

//Close table
echo " <tr>
	<td colspan=\"3\" align=\"right\"><b>Total:</b></td>

	mysql_close();

    Thanks again for the help.

    SESSION variables for a newbie

    in PHP Coding Help

    Posted

    Hi really struggling to get my head round session variables probably very easy for many of you out there.

     

    I am try to store four values against shopping cart. I want to store the product_id, the size, the colour and the qty ordered.

     

    Are session variables the best option?

     

    currently I have a dynamic loop that stores the product_id ($_SESSION[$product_id]['qty']) as the name of the variable and then stores the quantity against it, but this is no good as the colour and size get replaced everytime.

     

    Help would be greatly appreciated.

    First Shopping cart

    Hi I am new to this forum wondered if anyone could help. I am creating a shopping basket and want to store three session variables (quantity, colour, size) against one product ID ($pid). I am trying to modify I page that I already had working that simply stored the quantity and product ID. Help please???

     

    <?php

     

    include_once ('includes/header.html');

     

    echo '<body>';

     

    include ('includes/menu.html');

     

    //check adding to cart

    if (is_numeric ($_POST['pid'])) {

                //These are the variables I am posting to the page and need to store against the SESSION[cart] array

    $pid= $_POST['pid'];

    $colour = $_POST['pid'];

    $size = $_POST['size'];

    echo "{$_SESSION['cart'][$pid]}";

     

    //Check cart already contains one of these products

    if (isset ($_SESSION['cart'][$pid])) {

    $qty = $_SESSION['cart'][$pid] + 1;

    } else {

    $qty = 1;

    }

     

    //Add to the cart session variable

    $_SESSION['cart'][$pid] = $qty;

     

    }

     

    //Check if the form has been submitted (to update cart).

    if (isset ($_POST['submit'])) {

    foreach ($_POST['qty'] as $key => $value) {

    if (($value == 0) AND (is_numeric ($value))) {

    unset ($_SESSION['cart'][$key]);
