用于多个更新的PHP MYSQL多个If语句

有人能告诉我这些IF语句有什么问题吗

希望这足够了

基本上，这个表是针对一个携带3个dropships的jumpship的。我需要if语句来确定ds1中是否有dropship，然后dropship将被输入ds2列。如果ds1和ds2中有dropship，那么它将更新ds3列。如果这三个都有dropship，那么回显“this jumpship is full”将发布。

函数

mysql\u query

返回，您必须使用

mysql\u fetch\u assoc

进行数据提取。此外，查询中的数据应该是

这可能还不够。您是否收到错误消息？请解释您的期望值与您收到的值。它们似乎没有任何问题。但我们不知道

$ds1

、

$ds2

和

$ds3

变量在应用程序中代表什么。没有错误，但也不更新表。我将更新问题：所有的信息都在这里。好的，前两个更新可以工作，但由于某种原因，与ds2相同的ds3不工作。回显可以工作，但没有一个信息会出现在表中。

$ds_query = mysql_query(sprintf(
  "SELECT ds1, ds2, ds3 FROM gc3025_game_jumpships WHERE `id`='%s'",
  mysql_real_escape_string($jumpship)
));

$ds_result = mysql_fetch_assoc($ds_query);

if (!$ds_result['ds1'])
{
  mysql_query(sprintf(
    "UPDATE `gc3025_game_jumpships` " .
    "SET `ds1` = '%s', `ds1dest` = '%s', `ds1dz` = '%s', `ds1mission` = '%s' " .
    "WHERE `id`='%s'",
    mysql_real_escape_string($dsname),

elseif ($ds_result['ds1'])
{
  // and so on  
}
