php - 具有独特提交按钮的 echo 阵列

Question

基本上，此代码列出了“可用”挑战，其中 complete = 0 并在每个列表中都有一个接受submit 按钮。到目前为止，我一次只能列出一项，因为列出的多个按钮无法识别匹配 ID $echo 任何人都可以查看我的代码，看看我是否可以进行任何更改，以便我可以将 desc limit 10 从 1 更改，谢谢。

更改你的代码，这完全是一团糟，例如你的 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">';}      

可以写

$color="";
if($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\">";

但更好的是使用数组 $rand = array();并访问它们 $rand[0], $rand[1];等等

与 mysql_updates 相同

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");

可以改为

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

但是mysql_* 函数很旧，我建议将它们更改为 PDO，因为它们将来会被删除

使用转义函数和转换，因为您的脚本不安全!!

回答您的问题时，您可以使用其他形式的输入，例如单选、复选框或隐藏，并将这些字段的值放入循环中，然后使用提交来发送它们。
