PHP MySQL scoreboard with link to profile page - php

Question

I have a wordpress site with a scoreboard that gets results from a view in the wp database and I ve set up the board on a custom page template.My trouble is to link the players in the scoreboard to a new page with players stats etc. I want to be able to click the player name in the scoreboard and then get to a page with stats for that player.
Here is the relevant code that displays the scoreboard:
<?php //Table with SQL Query
$connection = mysql_connect('localhost', 'root', '');
mysql_set_charset('utf8',$connection);
mysql_select_db('worldsbestblog');
$query = "SELECT * FROM Sammenlagt LIMIT 0,20";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)){ //Loop through results
echo "<tr><td>" . $row['Dato'] . "</td>
<td>
" . $row['Navn'] . "
</td>
<td>" . $row['hull1'] . "</td><td>" . $row['hull2'] .
"</td><td>" . $row['hull3'] . "</td><td>" . $row['hull4'] .
"</td><td>" . $row['hull5'] . "</td><td>" . $row['hull6'] .
"</td><td>" . $row['hull7'] . "</td><td>" . $row['hull8'] .
"</td><td>" . $row['hull9'] . "</td><td>" . $row['hull10'] .
"</td><td>" . $row['hull11'] . "</td><td>" . $row['hull12'] .
"</td><td>" . $row['hull13'] . "</td><td>" . $row['hull14'] .
"</td><td>" . $row['hull15'] . "</td><td>" . $row['hull16'] .
"</td><td>" . $row['hull17'] . "</td><td>" . $row['hull18'] .
"</td><td>" . $row['Sammenlagt'] . "</td><td>" . $row['Par'] .
"</td><td>" . $row['Poeng'] . "</td></tr>"; //$row['index'] the index here is a column name
}
?>
I've seen countless similar questions where SESSIONS, $_POST and $_GET has been used though I havent been able to either understand or see how/if thats what's missing in order to make it work.
As it is now i get a URL showing the userid of player, but when clicked, wordpress cant find that page.
[edit]
OK I have done some editing and found an answer to my question. Unsure how to go about here on stackoverflow (direct me if I should do this elsewhere), but I want to show you what did the job so that the next guy will find this post with an explanation.
So here is the current code and thanks to #Cal Evans and #Hamed Momeni for helpful guidance:
Scoreboard goes:
$query = "SELECT * FROM Sammenlagt";
$result = mysql_query($query);
while($row = mysql_fetch_array($result)){ //Creates a loop to loop through results
echo "<tr><td>" . $row['Dato'] . "</td>
<td>
" . $row['Navn'] . "
</td>
<td>" . $row['hull1'] . "</td><td>" . $row['hull2'] .
"</td><td>" . $row['hull3'] . "</td><td>" . $row['hull4'] .
"</td><td>" . $row['hull5'] . "</td><td>" . $row['hull6'] .
"</td><td>" . $row['hull7'] . "</td><td>" . $row['hull8'] .
"</td><td>" . $row['hull9'] . "</td><td>" . $row['hull10'] .
"</td><td>" . $row['hull11'] . "</td><td>" . $row['hull12'] .
"</td><td>" . $row['hull13'] . "</td><td>" . $row['hull14'] .
"</td><td>" . $row['hull15'] . "</td><td>" . $row['hull16'] .
"</td><td>" . $row['hull17'] . "</td><td>" . $row['hull18'] .
"</td><td>" . $row['Sammenlagt'] . "</td><td>" . $row['Par'] .
"</td><td>" . $row['Poeng'] . "</td></tr>"; //$row['index'] the index here is a column name
}
?>
.../wordpress/teststats is a new page with a custom page template with the following code:
<?php
$spid = (int) filter_input(INPUT_GET,'id', FILTER_SANITIZE_NUMBER_INT);
$spillerquery = mysql_query("SELECT * FROM Sammenlagt WHERE spillerid='$spid'") or die ("Somthing went wrong!!");
if (mysql_num_rows($spillerquery) < 1){
die ("Couldnt find that player");
}
$navnequery = mysql_query("SELECT Navn FROM Sammenlagt WHERE spillerid='$spid'") or die ("Player does not exist");
$spillernavn = mysql_result($navnequery,MYSQL_BOTH);
?>
<h2>Her er <?php echo "$spillernavn"; ?> sine resultater</h2>
<?php
while($row = mysql_fetch_array($spillerquery, MYSQL_ASSOC)){
echo "<tr><td>" . $row['Dato'] .
"</td><td>" . $row['hull1'] . "</td><td>" . $row['hull2'] .
"</td><td>" . $row['hull3'] . "</td><td>" . $row['hull4'] .
"</td><td>" . $row['hull5'] . "</td><td>" . $row['hull6'] .
"</td><td>" . $row['hull7'] . "</td><td>" . $row['hull8'] .
"</td><td>" . $row['hull9'] . "</td><td>" . $row['hull10'] .

"</td><td>" . $row['Sammenlagt'] . "</td><td>" . $row['Par'] .

}
?>

Answer 1

Try this.
<?php
//Table with SQL Query
$player_id = (int) filter_input(INPUT_GET,'id', FILTER_SANITIZE_NUMBER_INT);
$connection = mysql_connect('localhost', 'root', '');
mysql_set_charset('utf8',$connection);
mysql_select_db('worldsbestblog');
$query = "SELECT * FROM Sammenlagt where player_id = {$player_id} LIMIT 0,20";
$result = mysql_query($query);
Although, I do agree with #Hamed that you should be using $wpdb instead of creating your own connection. This is assuming that your table is in the same database as your WordPress tables.

Answer 2

If you're actually using Wordpress I suggest you use the provided $wpdb object for your Database needs.
The other suggestion is when using Wordpress you need to use template files for creating different pages. You can create different page templates for various pages inside Wordpress. That way you can use the Wordpress rerouting engine for its powerful and easy features.
For example imagine you want to create a page for player stats. First create a file with the name tpl-player_stats.php inside your theme dir with the following header:
<?php
/*
Template Name: Player Stats Page
*/
And then inside Wordpress dashboar create a page and assign the above template to it. After that you can go to your page by going to http://example.com/your_page_slug/?id=player_id.
Generally this is how it's done with Wordpress. So I suggest you dig into that.
