Echo array with unique submit button

Question

Basically, this code lists the "Available" challenges where complete = 0 and has an accept submit button with every listing. So far I can only list one item at a time, because more than one button being listed cannot identify the match ID $echo Can anyone look through my code and see if I can make any changes so I can change desc limit 10 from 1 Thanks.

$query = mysql_query("SELECT `create_id` ,`value`, `player1`, `match_id` FROM `multiplayer` WHERE `complete` = 0 ORDER BY `value` DESC LIMIT 1");
echo '<table>';
while($rowtwo = mysql_fetch_array($query)){
    $format_coins = number_format($rowtwo['value']);
    $value = $rowtwo['value'];
    $create_player = $rowtwo['player1'];
    $echo = $rowtwo['match_id'];
    $create_id = $rowtwo['create_id'];
    $button =   '<form action="multiplayer.php" method="POST"><input type="submit" name="'.$echo.'" value="Accept"></form>';
    ///$button = '<a href="match/'.$echo.'.php">Accept</a>';
    echo   '<tr>
            <td><font size="2" face="Lucida Sans Unicode"><strong>'.$rowtwo['player1'].'</strong> has wagered '.$format_coins.'M/Gp   '.$button.'</td>

Change your code it's total mess for example your ifs

 if ($rand1 === 1) {     echo '<img src="images/Red_flowers.png">';} else if ($rand1 === 2) {echo '<img src="images/Blue_flowers.png">';} else if ($rand1 === 3) {echo '<img src="images/Yellow_flowers.png">';} else if ($rand1 === 4) {echo '<img src="images/Orange_flowers.png">';} else if ($rand1 === 5) {echo '<img src="images/Flowers_(pastel).png">';}
                if ($rand2 === 1) {     echo '<img src="images/Red_flowers.png">';} else if ($rand2 === 2) {echo '<img src="images/Blue_flowers.png">';} else if ($rand2 === 3) {echo '<img src="images/Yellow_flowers.png">';} else if ($rand2 === 4) {echo '<img src="images/Orange_flowers.png">';} else if ($rand2 === 5) {echo '<img src="images/Flowers_(pastel).png">';}
                if ($rand3 === 1) {     echo '<img src="images/Red_flowers.png">';} else if ($rand3 === 2) {echo '<img src="images/Blue_flowers.png">';} else if ($rand3 === 3) {echo '<img src="images/Yellow_flowers.png">';} else if ($rand3 === 4) {echo '<img src="images/Orange_flowers.png">';} else if ($rand3 === 5) {echo '<img src="images/Flowers_(pastel).png">';}
                if ($rand4 === 1) {     echo '<img src="images/Red_flowers.png">';} else if ($rand4 === 2) {echo '<img src="images/Blue_flowers.png">';} else if ($rand4 === 3) {echo '<img src="images/Yellow_flowers.png">';} else if ($rand4 === 4) {echo '<img src="images/Orange_flowers.png">';} else if ($rand4 === 5) {echo '<img src="images/Flowers_(pastel).png">';}
                if ($rand5 === 1) {     echo '<img src="images/Red_flowers.png">';} else if ($rand5 === 2) {echo '<img src="images/Blue_flowers.png">';} else if ($rand5 === 3) {echo '<img src="images/Yellow_flowers.png">';} else if ($rand5 === 4) {echo '<img src="images/Orange_flowers.png">';} else if ($rand5 === 5) {echo '<img src="images/Flowers_(pastel).png">';}      

can be written

$color="";
if($rand1 === 1||$rand2=== 1||$rand3=== 1||$rand4=== 1||||$rand5===1) $color="Red";   
else if($rand1 === 2||$rand2=== 2||$rand3=== 2||$rand4=== 2||||$rand5===2) $color="Blue";

echo "<img src=\"images/$color_flowers.png\">";

but better would be to use array $rand = array(); and access them $rand[0], $rand[1]; etc.

same with mysql_updates

mysql_query("UPDATE `users` SET `multi` = 0 WHERE `user_id` = $create_id");
                    mysql_query("UPDATE `multiplayer` SET `complete` = 1 WHERE `match_id` = $echo");
                    mysql_query("UPDATE `multiplayer` SET `score1` = $hostscore WHERE `match_id` = $echo");
                    mysql_query("UPDATE `multiplayer` SET `score2` = $userscore WHERE `match_id` = $echo");
                    mysql_query("UPDATE `multiplayer` SET `player2` = '$username' WHERE `match_id` = $echo");

can be changed to

 mysql_query("UPDATE `multiplayer` SET `complete` = 1, score1=$hostscore, score2=$userscore, player2=$username WHERE `match_id` = $echo");

but mysql_* functions are old I'd advice to change them to PDO because they will be removed in future

Use escape functions and casting because your script is insecure!!

Answering your question you can use other form of input like radio, checkbox or hidden and put the values in loop for such fields, then use submit to send them.
