Sorry that doesn't do me a huge bit of good since I have no clue how to
write java in the first place. Does anybody know where I can find or get an
example of php code that shows how to get all the selected items from a
multiselect listbox and loop through them printing them on the screen??

You can use this to work with. It's something I made some time ago, so it's
probably not the most optimal solution, but it gets the job done...
In this case it builds parameters for a SQL query, but it's easily modified
to suit your needs. The reason it's a 'for' loop and not a 'foreach' is
simply to make it simpler to keep track of how many items there IS in the
list, so that the OR part of the SQL query gets built correctly.
// load field list [multiselect box] from $_POST
$fields = $_POST['fields'];
// walk through all fields and build WHERE clause
for ($i = 0; $i < count($fields); $i++) {
if ($i > 0) {
$addtoquery .= ' OR ';
}
switch ($fields[$i]) {
case 'nick':
$addtoquery .= "`nickname` LIKE '%$search%' OR `akanick` LIKE
'%$search%'";
break;
case 'real':
$addtoquery .= "`fname` LIKE '%$search%' OR `lname` LIKE
'%$search%'";
break;
case 'email':
$addtoquery .= "`email` LIKE '%$search%'";
break;
case 'icq':
$addtoquery .= "`icq` LIKE '%$search%'";
break;
case 'aim':
$addtoquery .= "`aim` LIKE '%$search%'";
break;
case 'msn':
$addtoquery .= "`msn` LIKE '%$search%'";
break;
case 'yim':
$addtoquery .= "`yim` LIKE '%$search%'";
break;
}
} // end for - fields builder
The accompanying part of the form looks like this (don't ask why this is
done with a for loop, guess we had about those when I did it):
<td align="left" valign="top">Search in:<br>
<select name="fields[]" id="fields" size="4" multiple>
<?php
$fieldarray =
array('nick','real','email','icq','aim','msn','yim');
$fieldnames = array('Nickname','Real
name','Email','ICQ','AIM','MSN','YIM');
for ($i=0; $i < count($fieldarray); $i++) {
echo('<option value="'.$fieldarray[$i].'"');
if (! empty($_POST['fields'])) {
foreach($_POST['fields'] as $field) {
if ($fieldarray[$i] == $field) {
echo(' selected');
}
}
} else if ($fieldarray[$i] == 'nick') {
echo(' selected');
}
echo('>'.$fieldnames[$i]);
}
?>
</select></td>

hello all
I am foreach()ing through an array of ip addresses in a 'ban script' and
have the following php code:
foreach($ips as $ip) {
preg_match("/$ip/", $_SERVER[REMOTE_ADDR]);
$ban = TRUE;
}
This is great, but if 127.0.0 were in the ban list (for example) it
would still produce a ban as it partially matches.
How can I alter the above so that only *exact* matches are banned?
Much thanks!

If I've understood your question right:
foreach($ips as $ip) {
preg_match("/^$ip$/", $_SERVER[REMOTE_ADDR]);
$ban = TRUE;
}

I cannot fathom why you would use preg_match for this.
This will get an "exact match"...
if ($ip == $_SERVER[REMOTE_ADDR]) { $ban = true; }
Despite this being the worst idea I've ever seen, combined with a true lack
of understanding, I wish you well.

I'd rather go with something like this:
$banned_ips = array('123.123.123.123', '321.321.321.321'); // Banned IPs
if (in_array($_SERVER['REMOTE_ADDR'], $banned_ips)) {
die('Dude, you\'re banned!');
}
But if I were you I'd choose something more advanced.

And yes, I'm aware of the fact that 321.321.321.321 isn't a valid IP...

Ahh.. an oversight. The script has been cobbled together from a previous
version that supported partial matches. I'd just missed the obvious,
thankyou ;-)

There is no need to be insulting. I doubt very much anyone thinks your a

I think in_array() sounds like a great solution, wonder if it's faster
than comparing each ooe with == ? thanks!

Started to, but found I cant ;(
I need to get the key from the array also (for use in a corresponding
array) and with in_array() I couldnt find a way to do it. So, im just
using == which is lightning fast anyway so no worries :)
thanks again..

Hi Jerry,
I dunno if i got what you want to do... But
i would say :
1. Set a number to each day of the week (0 = sunday, 1 = monday, 6 =
saturday)
2. Get the date of today, so you can get the number of the day : $noDay
3. Do you SQL request from ($noDay + 1) to ($noDay-1)
(just need to test if $noDay > 6, then you loop it to 0)

No errors, that's correct, but it does return a boolean value. So are
you testing that return value?

You might want to try killing it right there with something like:
$test = mysql_query() || die('bad query: ' . mysql_error());

Zend.com / Leon Atkinson benchmarked it.
http://www.zend.com/zend/trick/tricks-sept-2001.php
<snip>
Conclusions
Based on the test results, it seems that keeping files in a database
cuts performance by approximately a third. It's hard to accept this
penalty in light of any meager advantages offered by keeping the files
in the databases instead of in a directory.

Hi Sebastian
Apologies for the random email, I wonder if you can take a look at a PHP5
aggregation issue I've run into.
I've modified your aggregation/delegate example[1] trying to get it to work as
there appear to have been API changes since that was written.
Getting the method of the delegate object and invoking it seems fine, however it
doesn't seem to be able to interpret params. When my delegated object's method
is invoked, the $parameters arg appears to be ignored, although it correctly
exists as an array of args when it gets to __call().
I've tried various formats for the args to invoke(), but can't get it to work -
any ideas?
I've modified the __call method of my class to look like this:
function __call($methodName, $parameters)
{
$delegated = false;
foreach ($this->aDelegates as $delegate) {
$method = new ReflectionMethod(get_class($delegate), $methodName);
$delegated = true;
return $method->invoke($delegate, $parameters);
}
if (!$delegated) {
PEAR::raiseError('Problem aggregating object',
SGL_ERROR_INVALIDCALL, PEAR_ERROR_DIE);
}
}
function addDelegate($delegate)
{
$this->aDelegates[] = $delegate;
}
Am running
- winXP
- PHP 5.02
- apache 2.052
thanks in advance,
Demian Turner

I am trying to validate an XML document, using
DomDocument::schemaValidate() as in the following code:
<?php
$txt =<<<EOT
<?xml version="1.0"?>
<Article xmlns='http://www.example.com/xml'>
<Item>ItemText</Item>
</Article>
EOT;
$dom = new DOMDocument();
$dom->loadXML($txt);
if ($dom->schemaValidate("Article.xsd")) {
print $dom->saveXML();
}
?>
The schema I am trying to validate against is:
<?xml version="1.0" ?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"; >
<xs:element name="Article">
<xs:complexType>
<xs:sequence>
<xs:element name="Item" maxOccurs="unbounded"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>
This produces the following output:
Warning: Element Article not declared in E:\PHPTest\testXML.php on line 10
Warning: Element Article not declared in E:\PHPTest\testXML.php on line 10
If I remove the default namespace from the article tag, the XML
validates correctly. I seem to recollect that namespace support is not
fully implemented, so my question is, is this a bug, or just something
not yet implemented, or is there an obvious blunder in what I am trying
to do, which I cannot see.
Best regards. . . Dusty

I've been looking around in the php documentation for a couple of hours
now but can't seem to find any functions to open a url in the current
browser window. Does php allow this? If so, could someone point me to a
link?
Basically what I'm trying to do is loop back in a login form until a
user enters a valid username/password and then redirect to that user's
personal info page.
Thanks for any help
