php loop from one table then loop from another table - php

Question

I tried searching but didn't find a good answer to my question. I have the following code for a loop:
<?php
$i=0;
while ($i < $num) {
$f0=mysql_result($sql,$i,"id");
$f1=mysql_result($sql,$i,"title");
$f2=mysql_result($sql,$i,"post");
?>
<p><?php echo $f1; ?></p>
<p><?php echo $f2; ?></p>
<p>Categories:</p>
<?php
$i++;
}
?>
<?php
$i=0;
while ($i < $num1) {
$f3=mysql_result($sql1,$i,"category");
?>
<?php echo $f3; ?>
<button>Edit</button>
<?php
$i++;
}
?>
The problem is that it is only looping up to <p>Categories</p>. It does not loop the categories and edit part which is the $f3 variable and Edit button. The categories table is a separate table so I had set up a different query ($sql1) than the posts table. How can I include those parts into the loop so they show for each post? I tried moving the $i++ part to the bottom but that just showed me the same post infinitely. Thank you for your help.

Embeded loops
<?php
$i=0;
while ($i < $num) {
$f0=mysql_result($sql,$i,"id");
$f1=mysql_result($sql,$i,"title");
$f2=mysql_result($sql,$i,"post");
?>
<p><?php echo $f1; ?></p>
<p><?php echo $f2; ?></p>
<p>Categories:</p>
<?php
$j=0;
while ($j < $num1) {
$f3=mysql_result($sql1,$j,"category");
echo $f3;
$j++;
}
?>
<button>Edit</button>
<?php
$i++;
}
?>

Udan's answer was correct but wasn't looping through my categories for each post for some reason. I decided to use a different loop and got it working. Posting here in case anyone else has the same problem.
echo "<h2>Posts</h2>";
$sql = mysql_query("SELECT id, title, post FROM posts") or die(mysql_error());
while ($test = mysql_fetch_array($sql)) {?>
<table><tr><td><input type="hidden" name="id" value="<?php echo $test['id']; ?>" /></td></tr>
<tr><td><?php echo $test['title']; ?></td></tr>
<tr><td><?php echo nl2br($test['post']); ?></td></tr></table>
<?php
echo "Categories:";
$sql1 = mysql_query("SELECT categories.* FROM categories INNER JOIN post_category ON categories.id=post_category.cat WHERE post_category.post='".$test['id']."'") or die(mysql_error());
while ($test1 = mysql_fetch_array($sql1)) {?>
<table><tr><td><?php echo $test1['category']; ?></td></tr></table>
<?php
}
?>
<button>Edit</button>
<?php
}
?>
