Hi Allen

I have been using includes for my content for a while now with no problems.
Suddenly it has stopped working, and it may or may not be from some changes
I made in my code structure.
I use default.php for most or all of my pages within a given directory,
changing the content via page numbers in the query string.
So on default.php, I have the following code:
<?php
if(isset($_GET['page']))
{
$thispage = $_GET['page'];
$content = 'content/'.$_GET['page'].'.inc';
}
> else
> {
> $thispage = "default";
> $content = 'content/default.inc';
> }
WOUW! this is a potential security issue!
I can add _any_ parameter to page, incl. an external one, so skip this
and use a switch instead
switch($_GET['page']) {
case "admin": $content = "content/admin.inc"; break;
case "member": $content = "content/member.inc"; break;
default: $content = "content/default.inc";
}
What use is $thispage by the way?
?>
<html>, <body>, <div> etc.
<?php include($content); ?>
I have a content subdirectory where I store all the pages with files such as
"default.inc, 101.inc, 102.inc, etc.
As I said, this has been working fine up until now, if I use the url
"user/default.php" or just "user/" I get this error:
*Warning*: include(content/.inc)
$_GET['page'] is not set, try and print it to the screen aswell...
[function.include<http://lpacmarketing.hostzi.com/user/function.include>]:
failed to open stream: No such file or directory in *
/home/a9066165/public_html/user/default.php* on line *89*
AND
*Warning*: include()
[function.include<http://lpacmarketing.hostzi.com/user/function.include>]:
Failed opening 'content/.inc' for inclusion
(include_path='.:/usr/lib/php:/usr/local/lib/php') in *
/home/a9066165/public_html/user/default.php* on line *89*
But if I use "user/default.php?page=default" I get the correct content.
It's acting as if page is set, but set to NULL, and then trying to find an
include at path "content/.inc" what's going on??

Are you sure that the paths are correct, including relative ones?

Instead of hard coding cases you can validate and constrain the input
with a regex. Much more flexible when adding content. I would also
add code to make sure the file exists, otherwise fall through to the
default.

You can import the templates by going to Tools > Options > Code Templates then
click on the "Import" button at the bottom of the window.
To use the templates:
1. Create or open an HTML page
2. Enter the name name of the template then press the "Tab" key on the keyboard.

I have a shopping cart type system set up which keeps track of the cart
contents using a SESSION variable, where $_SESSION['cart'][$item_id'] is
equal to the quantity, so the name/value pair is all the information I need.
But sessions are unreliable on the free server I am currently using for this
website (not my choice), so I had start using cookies because users were
being sporadically logged out, sometimes just on a page refresh.
I want to find a way to set a cookie to remember the cart items as well, and
I thought setting a cookie for each item/quantity pair was the way to go
until I started trying to figure out how to unset all those cookies if the
user empties their cart.
Is there any way to set cookies with an array for the name? Intead of
$_COOKIE['item_number'] have $_COOKIE['cart']['item_number'] like I have the
SESSION?

What about storing a unique ID in the cookie, and matching it up with
information for that user in a database. It's sort of simulating a
sessions, but without the session handler getting involved, which looks
slightly messed up from what you've said.

Don't do it this way. At some point (don't know if it's still true), IE had a
limit of 20 cookies per domain - this includes cookie arrays. The proper way to
do this would be to hold some sort of key in a cookie:
user_cart = 'some unique value for this user'
Then, in your PHP code, grab the value of $_COOKIE['user_cart'] to reference
data in a database. Then, you pull the information from the database with this
unique key and use it to display the appropriate items. This is the most secure
way to do it (with the proper security measures ;) and it doesn't put 100's of
needless cookies on the user's machine.
Hope this helps.

First, don't use multiple cookies; already covered elsewhere. Second,
you can serialize/unserialize array data and store it compactly in a
cookie. See the serialize() and unserialize() functions on php.net.

Hey all,
I have an HTML field like this
<input type="text" name="qty[]" value="!!quantity!!" size="4"
style="text-align: right;" onblur="calculateBidUnit();">
... and what I need to do is pass to the calculateBidUnit
function the value of quantity, do a calculation on it and
plug into this field.
<input type="text" name="bid_unit_value[]" value="" size="4">
Which of course I know how to do for non-array values, but not
sure how to get the values to do the calculation on the JS
side if the fields are in an array.
Any help, as always, is greatly appreciated,

This question is probably more appropriate for a JS list... but I'm not mean,
so I'll let you know. The easiest way would be to update the blur event qty
input:
onblur="calculateBidUnit(this.value);"
Now you have the value sent to that function. Another way would be to give your
input and output an id each - let's say 'qty' and 'bid_unit_value',
respectively. Then reference those ids in your function. This gives you the
following:
<input type="text" name="qty[]" value="!!quantity!!"
onblur="calculateBidUnit();" id="qty" />
<input type="text" name="bid_unit_value[]" value="" id="bid_unit_value" />
<script type="text/javascript">
function calculateBidUnit () {
var qty = document.getElementById('qty');
var buv = document.getElementById('bid_unit_value');
buv.value = qty.value;
}

I'll give you a small warning. All browsers are not alike, so my recommendation
would be to use a library that handles the cross-browser compatibility portion
of javascript (I use Mootools). Nonetheless, the above *should* work. Learning
the bare bones of javascript will help with the more complicated stuff and
you'll be smarter for it! =P

Hey Philip,
But will that ID value identify the right member of each
array? I thought about that but just assumed that it would not.

This question is probably more appropriate for a JS list... but I'm not mean,
so I'll let you know. The easiest way would be to update the blur event qty
input:
onblur="calculateBidUnit(this.value);"
Now you have the value sent to that function. Another way would be to give your
input and output an id each - let's say 'qty' and 'bid_unit_value',
respectively. Then reference those ids in your function. This gives you the
following:
<input type="text" name="qty[]" value="!!quantity!!" onblur="calculateBidUnit();"
id="qty" />
<input type="text" name="bid_unit_value[]" value="" id="bid_unit_value" />
<script type="text/javascript">
function calculateBidUnit () {
var qty = document.getElementById('qty');
var buv = document.getElementById('bid_unit_value');
buv.value = qty.value;
}
</script>

Each text input will only contain 1 value... and contain 1 unique "id." So, if
you have multiple input boxes with the same name (qty[]), only the $_POST
output will contain an array of each value. See below...
<input type="text" name="qty[]" value="1" id="qty1" onblur="calc(this.value);"
/>
<input type="text" name="qty[]" value="2" id="qty2" onblur="calc(this.value);"
/>
<input type="text" name="qty[]" value="3" id="qty3" onblur="calc(this.value);"
/>
<input type="text" name="bid_unit_value[]" value="" id="buv" />
<script type="text/javascript">
function calc (value) {
document.getElementById('buv').value = value;
}
</script>
When you blur qty1, buv will receive the value 1; blur qty2, buv will be 2; and
so on. The last input box that you blur on will determine buv's final value
(unless you throw in some logic to handle this)...
<script type="text/javascript">
function calc (value) {
var buv = document.getElementById('buv');
if (buv.value == '') buv.value = value;
}
</script>
So, let's say you blur on qty2 and then submit the form, your PHP script will
have this in $_POST...
Array
(
[qty] => Array
(
[0] => 1
[1] => 2
[3] => 3
)
[bid_unit_value] => Array
(
[0] => 2
)
)
If this is not what you're wanting, you will need to modify the behavior above.
If you're wanting the bid_unit_value to contain all the values of each blur,
you may want to do something like this...
<script type="text/javascript">
function calc (value) {
var buv = document.getElementById('buv');
if (buv.value == '') buv.value = value;
else buv.value += '|'+value;
}
</script>
Which may result from each blur in $_POST to be...
Array
(
[qty] => Array
(
[0] => 1
[1] => 2
[3] => 3
)
[bid_unit_value] => Array
(
[0] => 2|1|3
)
)
Or something along those lines. Then you can just explode() on that first index
to get individual values. Maybe you can clarify your ultimate goal and we can
assist you in what the best plan is.
Hope that helps,
~Philip

I'm using PHP 5.2.11 with Apache 2 (and i also tried Apache 2.2)
However, when I add this entry to my httpd.conf:
<code>
LoadModule php4_module "C:/Program Files/php/sapi/php4apache.dll"
</code>
Apache will crash when trying to start the service.
If I comment the line out, Apache starts just fine.
Thanks for your help.
