No. PHP is on the server, not the client-side. If you can't use
something like target="_blank" in your xhtml, then consider using
Javascript. It's not the ideal solution, as it won't work where
scripting is disabled or not available.

Hi Alex,
I have a php file I made just a few months ago.
It takes a gif, jpeg or png of any size and sizes it
proportionately to a specified size and then outputs a png.
If the image is a transparent png or transparent gif, it will
still hold the transparency.
This is just a test page and it tested ok for me, but it is my
first one. I also tested it on PHP 5. Dont know about
compatibility to older versions.
Knowing that, here you go.

Hi Ash,
Thanks for your suggestion. I think this is where my confusion is. I
understand how to use imagecolorallocatealpha() to for example create a 50%
transparant colour, and apply it to a new rectangle for example.
I dont understand how to "apply" it to a new source image, for example
$src = imagecreatefrompng('test.png');
// Something here (maybe imagecolorallocatealpha()) to make this
50% transparent- either on its own, or make it 50% transparent as part of a
copy onto a new image
I had thought that imagecopymerge would help me with this, but it seems not.
I'm currently looking through Karl's example to see if I can work it out,
but if anyone can point out a super-simple way of achieving the pseudo-code
above, i'd be very grateful!
Cheers,
Alex

Hi,
I am trying to create a news feed page that loads a number of different feeds
depending on what options the user selects. For some reason, I could not figure
out how to get the dom document to "append" the different xml documents that
get created.
Below is the code, and obviously now every time when I try to have a new item
selected, then it displays that element's
<?php
$q=$_GET["q"];
$q2 = explode(" ",$q);
$count = count($q2);
for($i=0;$i<$count;$i++) {
//find out which feed was selected
switch ($q2[$i]) {
case "Weather":
$xml=("http://rss.weather.com/rss/national/rss_nwf_rss.xml?cm_ven=NWF&cm_cat=rss&par=NWF_rss";);
break;
case "NFL":
$xml = ("http://www.nfl.com/rss/rsslanding?searchString=home";);
break;
default:
exit;
break;
}
}
$xmlDoc = new DOMDocument();
$xmlDoc->load($xml);
//get and output "<item>" elements
$x=$xmlDoc->getElementsByTagName('item');
for ($i=0; $i<=4; $i++)
{
$item_title=$x->item($i)->getElementsByTagName('title')
->item(0)->childNodes->item(0)->nodeValue;
$item_link=$x->item($i)->getElementsByTagName('link')
->item(0)->childNodes->item(0)->nodeValue;
$item_desc=$x->item($i)->getElementsByTagName('description')
->item(0)->childNodes->item(0)->nodeValue;
echo ("<p><a href='" . $item_link
. "'>" . $item_title . "</a>");
echo ("<br />");
echo ($item_desc . "</p>");
}
?>
Is there such a function where I could allow my dom document here append and
not have to create a new one every time when a new selection is made?
Thanks for your help.
Alice

you might have an easier time w/ SimpleXML for this task; have a look at the
examples:
http://us.php.net/manual/en/simplexml.examples-basic.php
the other thing i find strange about this code is the xml parsing assumes a
similar schema when the source urls are from seemingly totally disparate
domains, and topic .. id guess it sheer coincidence they have overlapping
schemas at all.

I am not sure what you mean in your second point, but I can explain the first
one. I am using PHP to parse RSS feeds, so that is why they all look the same.
Or, what do you mean here? I checked out your example, but my problem here is
that I cannot get the XML Dom document to append when I make a new selection. I
am hoping that it would create a new sub document of some sort beneath the new
one, instead of overwriting the entire document.
Am I making sense here?

umm, i dont see you making any modifications to the original document,
$xmlDoc in your code. thats why i suggested simple xml, its the go-to imo
if all you need to do is traverse an existing document. DOM is much better
if you need to edit the document. having said that if you wanted to append
a new DOMNode to an existing one, you would use the appendChild() method.
> Am I making sense here?
no because youre not editing the DOMDocument in your code, youre just
reading a document; what is getting overwritten here? im not entirely sure
what youre trying to accomplish.

Hello All,
I am trying to figure out how to create files when a user submits a form ...
I have seen something about '*fopen*' , is that the direction I should
be going?
Here is what I am trying to accomplish:
I am creating a program to keep track of recipes for my wife. I have
have page set up where she can put the name of the recipe, the
ingredients, and the amounts of each ingredient.
Then she clicks "Submit"
I would like a html file with the name of the recipe to be created ie
*cookies.html *with a link to the cookies.html created on another page.
*
*I hope this makes sense, and thank you all for your time...

It might sound overkill, but I'd use a database for this. All the
recipes can be stored in a MySQL database, and then you can use a simple
couple of queries to produce the recipe list and the recipe pages
dynamically. This also has the advantage that it's very easy to search
the recipe list when it becomes larger, and if you ever want to change
the layout/presentation of the whole system you won't have to recreate
all the recipe pages.
The DB could have several columns labelled: id, name, ingredients,
method
So, the form page (lets assume it's called add.php) could submit to
itself which then adds the recipe to the DB with a query like:
INSERT INTO recipes(name, ingredients, method) VALUES($name,
$ingredients, $method)
This is only a very simple example which could be extended to use
another table for ingredients for a recipe. Don't forget to sanitise any
input coming from the form with mysql_real_escape_string() for inserting
it into the DB.
The list.php page could just use a simple query like:
SELECT id, name FROM recipes
And then create a link to each recipe in the form: recipe.php?recipe=id
(where id is the numerical value used in the DB) and that would then use
a query like:
SELECT * FROM recipe WHERE id=$recipe
MySQL is available on most hosting that you'll find has support for PHP,
and every Linux distribution I've seen has it too.

Thank you Ash for the quick reply.
I was actually looking at using a database too... and I am testing out a
few different ones (SQLite and MySQL)
I appreciate the extra information, it will be helpful in the future :-)
/On a side note:
I am having some issues with connecting to a SQLite database right now
... I'm getting the following error "Fatal Error: 'sqlite_open' is an
unknown function"
But I'm putting that on the side right now.
/I wanted to try a different approach by just creating the recipes in
individual html files for the time being.
Do happen to know how to create html files from a php form?
Thank you.

I think the docs are still screwed up. Try sqlite3_open() instead and
see if that works. Also, check phpinfo() to see if the SQLite/SQLite3
modules are loaded.

Hi All!
I am looking for a solution, I want a user to do a single Login only on a PC
.
E.g. If a User has logged on my website website.com in Internet explorer,
then he cant login on same website in another browser like Firefox etc with
same loginid or another.
Can I trace MAC address of a single machine to solve this issue?
Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will
work for all browsers in a single machine..
I hope You will help me out

Hi Jagdeep,
I would make an "active users" table in your database that the
username gets loaded into on successful login
and in your login script also check this table before letting them
log in.

The browser IP address works for us quite reliably. Once logged in, you get a
message saying already logged on ... and where ... but it does need a little
help if the user closes the browser without logging out. One needs a facility to
'bounce' a user now and again .... however some remote users may well have
'floating' IP addresses :(
Cross browser on the same machine may be a little more problematic! How would
one know that it's not just from another windows of the same browser. Browser
sniffing should allow that to be included, but we've not needed to go that far yet.
Or is there a concept of GLOBAL COOKIE / Cross Browser Cookie which will

Unfortunately not ...

Or in some cases, they may have multiple internet connections. I used
to have 2, 1 cable and 1 DSL. I used FreeBSD's PF to do 'load
balance' ;) It works really well with any apps that do multiple
connections.

Don't rely on IP addresses staying the same for a user, it's not safe
in any way and not needed anyway. Karls method is probably the best
bet - just remember to record "last accessed time" so anyone not
accessing for more than 15-20 minutes will succeed if trying to log in
again.

Hi,
yes, I can make a databse table to record LOGIN details, But I want that No
other user can login on same machine on smae or another browser.
E.g.
If user1 has logged in from IE then user2 should not login from Firefox or
Chrome etc..
I need ONLY ONE USER ACCESS AT SAME TIME ON SAME MACHINE (On Same or Other
broswers)

I'm doing almost exactly that on my CMS system. But we have the advantage that
it is intranet, so we can cleanly identify the machines. Once a counter position
is in use no one else can log in to that machine, and while loged in there a
user can't login again. We can't easily add a 'timeout' since some interviews
can take over an hour and the position remains locked for the whole period, but
supervisor access allows a 'stuck user' to be bounced so they can log in again.
If you don't have such control over the machines, then you may need to do a
little more work to build up a list of 'active machines' in parallel with the
'active user' table.

You lost me on that one.
You want it so that multiple users can log in, but they have to be on
separate browsers?

Hi J,
Well, if you have an active users table with a users name in it and
you check when logging in to see if that users name is in that table,
They can not log in again. No matter what machine or browser they are
in.
As far as another user logging in on that same machine, you could
match a cookie on the machine and the database that holds what
browser they are using and username, an MD5 ip, etc.
But someone can always delete cookies and some even know how to
bounce ip addresses, so unless you have a bunch of hackers using your
machines, these suggestions should work.
Unless someone else has a better suggestion.
GL,
:)

Hi.
I'm doing the 5.3-strict thing, and am removing all my
passing-by-reference muck from a script of mine.
But i've run into a problem;
I use the following construct to push new values fairly deeply inside
an array structure;
$chase = chaseToReference ($wm, $path);
$arr = result($chase);
$arr[$v] = $lid;
$path is a flat-list array of indexes in $wm that have to be traversed
to get to the right portion of $wm.
a debug-dump of $wm and $arr after running this code shows $arr
correctly updated, but $wm not. :((
here are the functions involved, any help is much appreciated.
function chaseToReference (&$array, $path) {
if (!empty($path)) {
if (empty($array[$path[0]])) {
return badResult (E_USER_WARNING, array(
'msg' => 'Could not walk the full tree',
'$path' => $path,
'$array (possibly partially walked)' => $array
));
} else return chaseToReference($array[$path[0]], array_slice($path, 1));
} else {
return goodResult($array);
}
}
function result(&$r) {
return $r['result'];
}
function goodResult(&$r) {
$r2 = array (
'isMetaForFunc' => true,
'result' => &$r
);
return $r2;
}

changed all function-definitions to include a "&" before their name,
no change in behavior though..

After a quick glance, I can't actually see any modifications to $wm in
this code.

And then, change the calling code to:
$chase = &chaseToReference ($wm, $path);
$arr = &result($chase);
$arr[$v] = $lid;
and it works :))

I encode my password with md5 base 64 ..on the php side but
i have a problem with the POST that this function i using on my form.
after posting my data + is replaced with space
I came out with that explanation after a lot of tries and echos in my code
files i found out that
after using numbers ,onlu on that case, in the password field the space
between the encoding was replaced with a + or / sometimes
i tried to remove the + or / but still i get the same results
any ideas
