PHP - Decimals (european Style)

Hi - To me, this doesn't make sense.   My Order form uploads product weights in an array . If I echo out those weights they are fine ie 25.25

However, when I try to update the DB for some reason, the for loop strips out all but the first digit, so 25.25 becomes '2' or indeed if I had entered 9999999 it just '9' is entered in to the DB.

I have tried using number_format to pre-process the decimals, - but I get an error saying you can not use it in a write format.

Many Thanks to anyone who can help with this  !!


PS - I have abbreviated the below code for clarity:

Code: [Select]
$weight = $_POST['weight'];

        for ($i = 0; $i < $numloops ; $i++)

      {
       $sql ="
UPDATE `confirmedorder`
SET orderid = '$orderid[$i]', weight='$weight[$i]',status='finished', ordervalue='$ordervalue'
WHERE customerid = $customerid
";
$this->db->query($sql);
}

I want to find the first sentence in a string without counting decimals. Here is the code I have, but I still want it to display the decimals, but I don't want it to count as the end of a sentence.

$content = "This is my test string which is 3.5% of what I'm trying to do. This is only a test.";

Code: [Select]
function first_sentence($content)
 {
if(preg_match('/[0-9]+\.[0-9]/', $content, $num)) {
$number = "$num[0]";
$content = ereg_replace("$number","", $content);
}
preg_match('/^.*[^\s](\.|\?|\!)/U', $content, $match);
$string = $match[0];

$title_count = strlen($match[0]);
if($title_count > "6"){
return "$match[0]";
}
else {
$content2 = ereg_replace("$match[0]","", $content);
preg_match('/^.*[^\s](\.|\?|\!)/U', $content2, $step);
return "$match[0] $step[0]";
}}
Currently this is what it displays: This is my test string which is % of what I'm trying to do.
This is what I want it to display: This is my test string which is 3.5% of what I'm trying to do.

Ok so say I have php do some calculations for me

Code: [Select]

$Value1 = 300;
$Value2 = 100000;
$FirstRatio = $Value1 / $Value2;

$Value3 = 8000;
$Value4 = 6000000;
$SecondRatio = $Value3 / $Value4;


$FirstRatio = 0.003
$SecondRatio = 0.0013

How would I go about doing these calculations and then sorting $FirstRatio and $SecondRatio and then it would take the highest ratio ($FirstRatio) and it would echo the value?

Hi there.

I am trying to display numbers if they have the numbers like:

number_format($price,2)

This gives us two decimal places i.e 7.23

Now thats fine, I would like to round the last two decimal places. I would like to make it 7.25, (rounding it from 7.23 to 7.25)

Similarly making:

12.44 to 12.45
33.18 to 33.20
52.13 to 52.15

So actually rounding the last two places. Coz obviously customers won't be able to pay 52 dollars 13 cents. So therefore rounding the last cent's (decimal part) making it to 52.15

Thank you.

All comments and feedback are welcomed.

How can I add color: #000; to this?

Thanks,  

Background:
I'm comparing 2 styles of Ajax:
1.) "jquery style"
2.) "ActiveXObject Microsoft.XMLHTTP style"

Question:
Is one better (faster, more cross-browser compliant) than the other?

My experience:
Both seem equally fast. The Microsoft style is a bit longer, but I don't have to load jquery.js to my page!

Code Examples:

Jquery style on my PHP page:

function getInfo(ProductNumber){
$.ajax({
url:'Ajax-PHP-Page.php?ProductNumber='+ProductNumber,
success: function(html) {
document.getElementById("my_div").value = '';
document.getElementById("my_div").value = html;
}
});
}

Microsoft style on my PHP page:

function getInfo(ProductNumber) {
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }
        xmlhttp.onreadystatechange = function() {
            if (this.readyState == 4 && this.status == 200) {
                document.getElementById("my_div").value = this.responseText;
            }
        };
    xmlhttp.open("GET","Ajax-PHP-Page.php?ProductNumber="+ProductNumber,true);
  xmlhttp.send();
}

Thank you!!

Hi,

I use the following style for building my websites, I understand this is a fairly common style and was wondering if there is a name for it?

Code: [Select]
<?php

include ('templates/header.php');

switch ($_GET['action']) {

case "home" :
display_home();
break;

case "services" :
display_services();
break;

case "testimonials" :
display_testimonials();
break;

case "contact" :
display_contact();
break;

default :
display_home();
break;

}

include ('templates/footer.php');

// Function list

// Display home page
function display_home(){
$qid = mysql_query('SELECT * FROM testimonials ORDER BY RAND() LIMIT 0,1;');
include('templates/home.php');
}

// Display services page
function display_services(){
include('templates/services.php');

Hello!

Quick question which I hope someone will be able to answer!

How do I apply this style Code: [Select]
<style type="text/css">
.text { font-family: Arial, Helvetica, sans-serif;
color: #666;
font-size: 12px;
font-weight: normal;
text-decoration: none;
margin-right: 15px;
}
</style> to the code below, which will become text in an PHP generated HTML email Code: [Select]
$message .= "Dear ".clean_string($Name).",\n\n";
$message .= "Thank you for your message.\n\n";
I beleive I need to use a css span class but can't get it to work!

Thanks!

Hi,   I am trying to align sections of my CSS layout side-by-side, but I am having problems with it.   I expect the left sidebar (#aside) with a 30% width to meet with the content section (#content) of the width of 70%. But, the changes I make are not translating as expected.   See attached screenshort of what is happening and the CSS code bellow:

#container
{
	margin: 0 auto;
	width: 800px;
	background: #fff;
}

#header
{
	background: #5a83c3;
	padding: 20px;
}

#header h1 { margin: 0; }

#navigation
{
	float: left;
	width: 100%;
	background: #d1dceb;
		border-top: 1px solid #fff;
}

#navigation ul
{
	margin: 0;
	padding: 0;
}

#navigation ul li
{
	list-style-type: none;
	display: inline;
}

#navigation li a
{
	display: block;
	float: left;
	padding: 5px 10px;
	color: #fff;
	text-decoration: none;
	border-right: 1px solid #fff;
}

#navigation li a:hover { background: #383; }

#content-container
{
	float: right;
	width: 100%;
	background: #FFF url(layout-two-liquid-background.gif) repeat-y 68% 0;
}

#content
{
	clear: right;
	float: right;
	width: 70%;
	padding: 10px 0;
	margin: 0 0 0 4%;
	display: inline;
	background: #dfe6ef;
	border-top: 1px solid #fff;
	border-left: 1px solid #fff;
	border-bottom: 1px solid #fff;
}

#content h2 { margin: 0; }

#aside
{
	float: left;
	width: 20%;
	padding: 10px 0;
	margin: 0 3% 0 0;
	display: inline;
	background: #d1dceb;
	border-top: 1px solid #fff;
}

#aside h3 { margin: 0; }

#footer
{
	clear: right;
	background: #d1dceb;
	text-align: right;
	padding: 20px;
	width: 68%;
	float: right;
	overflow: hidden;
}
#footer p.left {

I am making a simple shopping cart. To add a product, I use this code:

Code: [Select]
<?php

if (isset ($_GET['action']) && $_GET ['action'] == 'add' ) {
$id = intval($_GET['id']);
$_SESSION['cart'][] = $id;
}
$cart = $_SESSION['cart'];
if (!$cart) {
echo "No product in cart.";
} elseif ($cart) {
foreach ($_SESSION['cart'] as $id) {
echo $id;
}
}
?>
<A href="index.html?action=add&id=1">Add to cart</A>

I am going to be selling t-shirts, I'm going to need a size along with the product ID, so now I need to add a 'size' value. I've tried simply doubling up on the code above with this code, but it isn't working. I was wondering if I am going the right way about it?

Code: [Select]
<?php
if (isset ($_GET['action']) && $_GET ['action'] == 'add , size') {
$id = intval($_GET['id']);
$_SESSION['cart'][] = $id;
$size = intval($_GET['size']);
$_SESSION['cart'][] = $size;
}
$cart = $_SESSION['cart'];
if (!$cart) {
echo "No product in cart.";
} elseif ($cart) {
foreach ($_SESSION['cart'] as $id) {
echo $id;
}
foreach ($_SESSION['cart'] as $size) {
echo $size;
}
}
?>
<A href="index.html?action=add&id=1&size=sizel">Add to cart</A>
