PHP - Regex For Middle Initial

I have a regex that validates a string. I want to ensure there is no space in the string. Thus far I have used the negative look ahead regex construct as shown below to match strings without spaces.

(?!.*(\s))

While this prevents space in between a word, all strings with space characters at the end or beginning are getting validated. I do not want that at all.   This is the full regex script below:

$string = "#JebiamgoOeing0";
if (preg_match('/^.*(?=.{8,})(?!.*([A-Za-z0-9])\1{1})(?=.*[a-z])(?=.*[A-Z])(?!.*(\s))(?=.*[\d])(?=.*[\W]).*$/', $string))
{
    "do something";
}
else
{
   "do something else";
}

I need help in resolving this.   Thank you.

Okay, here's what I'm doing. It's sort of like a market script.

When someone wants to buy something, they choose from a drop down the item they wish to buy. However, there is a setup cost for it to be started. Then, based upon the length they choose (anywhere from 1 - 12 months), the cost will add up.

My questions a

Is it possible to assign a setup cost? How can I make it so that, while some things will be, say $2 a month, others will be $3 or other amounts?
Here's what I have so far, to try and figure this out. Feel free to laugh... Or if you could point me to an example of something like this, I'd be very appreciative! Thanks!!


function ChangeInitialCost(){
$cic = ($_POST['newpremium']);
if (($cic == "clan") || ($cic == "guild") ||  ($cic == "house") || ($cic == "militia")){

}


And the form I have: (I haven't entered a submit button yet...)
Code: [Select]
<table width="200" border="1">
  <form action="premium.php" method="post" name="purchase">
  <tr>
    <td>Premium:</td>
    <td><select id="newpremium" name="newpremium">
<option value="casino">Casino</option>
<option value="clan">Clan</option>
<option value="guild">Guild</option>
<option value="house">House</option>
<option value="militia">Militia</option>
</select></td></form>
  </tr>
  <tr><form action="premium.php" method="post" name="length">
    <td>Length:</td>
    <td><select id="length" name="length">
<option value="0">-----</option>
<option value="1">One Month</option>
<option value="2">Two Months</option>
<option value="3">Three Months</option>
<option value="4">Four Months</option>
<option value="5">Five Months</option>
<option value="6">Six Months</option>
<option value="7">Seven Months</option>
<option value="8">Eight Months</option>
<option value="9">Nine Months</option>
<option value="10">Ten Months</option>
<option value="11">Eleven Months</option>
<option value="12">Twelve Months</option>
</select></td></form>
  </tr>
  <tr>
  <td>Cost:</td>
  <td>SOME TYPE OF FUNCTION</td>
</table>

I am trying to initialize every value in my $errors array to have a value of '' so I don't get "undefined variable" errors!

Here is what I have...

Code: [Select]
//Put in some values and then try to erase them.
$errors = array('firstName' => 'Enter First Name', 'lastName' => 'Enter Last Name');

//Want an initialized array.
foreach($errors as $key => $value){
$key = '';
}

But that doesn't seem to work when I run

Code: [Select]
print_r($errors, true);

Thanks,


Debbie

I'm trying to get a count of how many topics someone starts in a forum.  I use XenForo, and they only count Posts, but I can order Posts by post_id and group those posts by thread_id to determine the initial instance of that topic.  The problem I'm having is output.

I'm getting the right User info, but the output is offset by one row:  

User 1 | 0 topics (because $c=0)

User 2 | 128 topics (but those are User 1's #)

User 3 | 0 topics (but those are User 2's #)

User 4 | 141 topics (but those are User 3's #)

etc

 

I realize as I play through the logic of the code, it's printing in that order.  I can't seem to get the right order.  I've tried various ways, with a couple of extra IF statements in there too.  

 

$query = "select thread_id,user_id,username from 
(
select * from xf_post 
order by post_id
) x
group by thread_id
order by username,thread_id";

$results = mysqli_query($con,$query);
		echo mysqli_error($con);
		
		$c=0;
		$currentID = false; 

			while($line = mysqli_fetch_assoc($results)) {
				
				
				if ($currentID != $line['user_id']) {
				
							echo '<div>' . $line['username'] . ', ' . $c;

							$currentID = $line['user_id'];
							$c=0;
				}	
				else {
					$c++;
				}
					
			}

 

A friend of mine is looking at relaunching a site he used to run and I am going to try to persuade him to move over to a dynamic site.

The site is a Football Clubs history site and contains around 2,000 games and several hundred players. The obvious advantage of a dynamic site is that even the bits I just mentioned run to around 2,500 static pages, which could be reduced to just 2 pages if dynamically driven.

I am fairly confident that I can do the conversion, but there is one thing that I already know I may struggle with and that is the page which shows game, births and deaths on this day in history. A rough example (using a very heavy Javascript code) can be found at http://follyball.co.uk/jeff/.

In a simplified form (ignoring for now the foreign keys to relationships that these tables actually have) there will be two tables
GAMES
game_id | date | competition | opponent | score | attendance

PLAYERS
player_id | surname | firstname | date of birth | date of death

What I would be looking for is a way to take todays date, and find any corresponding records in games.date, players.date of birth, players.date of death on the same date in previous years. This would be simple to do as three different queries but as I would like to actually mix the three and show them in date order, I would like to do it in one query, presumably using UNIONS.

On top of this, I would also like a slightly different output for each different set, for example, if it was a game I would like
year, competition, opponent, score, attendance,

Whereas if it is a players birth or death, I would like it to show something like
firstname surname was born in year

Before I go delving too deep into how it may be done, I would like to know if it can be done! I cannot see why it would not be able to generate this but if it is going to be way out of my ability, then I will look for another option!

Thanks in advance
