i need some quick help, this project has been way over due and ive wasted huge amounts of time researching on my own and bothering others trying to figure this out and i just cant leave it be its like a damn drug. im desperate folks!


my 2 tables,

movies:    id - title - category - url

categories: id - category (FK)

what im trying to do is have every category list as a table and then list the movies owned by that category in them, example:

Category 1
---------------
title
title

Category 2
--------------
title
title

Category 3
--------------
title
title


the code im using is

Code: [Select]
<?php
$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_select_db("mydb", $con);
$result = mysql_query("SELECT a.ID, 
       a.Title,
       b.Category,
       a.URL
  FROM Movies AS a 
     JOIN Categories b ON a.Category = b.ID
  ORDER BY b.Category");
echo "<table border='1'>
<tr>
<th>Title</th>
<th>Category</th>
</tr>";

while($row = mysql_fetch_array($result))
{
echo "<tr>";
echo "<td width='100'><a href='".$row['URL']."'>" . $row['Title'] . "</a></td>";
echo "<td width='150'>" . $row['Category'] . "</td>";
}
echo "</table>";

$result2 = mysql_query("SELECT ID,Category FROM Categories");

while($row2 = mysql_fetch_array($result2))
{
echo "<tr>";
echo "<td>" . $row2['Title'] . "</td>";
echo "</tr>";
}
echo "</table>";

mysql_close($con);
?>
but obviously this code gives me a single table that lists all the titles with category next to them and then under the table it lists my categorys from left to right and its looks like

Title     Category
---------------------
title1     Drama
title2     Comedy
title3     Horror
title4     Thriller
--------------------
DramaComedyHorrorThriller



what exactly do i need to change to display the results i want ?  btw dont hammer me on using 2 while loops, some tell me i need 2 and others say 2 is pointless. i myself have no clue!

Hi!

I want to be able to create a dynamic tournament bracket but not sure where to get started,
right now all the template brackets have been hardcoded, i.e. http://teamx1.com/templates/64.html

Can you someone put me in the right direction by using PHP to create and write this file?
I want to be able to create 64 + brackets but hardcoding is a huge headache and mistakes easily done.

Thanks all.

I've made my first object that will addition an array but it doens't seem to be working as it echo's out 0.

here is my script
<?php

class A {
public $sum = 0;

function addition($values){

foreach ($values as $numbers){
$this->sum = $number + $this->sum;
}

echo $this->sum;
}


}

$a = new A();

$array = array(10, 15, 25);

echo $a->addition($array);

?>

I don't see what I'm doing wrong. Any direction would be greatly appreciated.

Does storing multiple values in 1 database field with a varchar let's say set at 150, all separated by
"|'s" so I don't have to create a field name for each one is it better performance wise or no? (storing 6-7 different |'s that will be outputted with a array ofc)

?
