我有这段代码:
if (condition){ //number1
if (condition){ //number2
action
}
}
else{
action
}
现在,如果嵌套的if语句,数字2,结果为false,是否可以将程序“重定向”到外部的else语句,而不是像这样创建一个嵌套的else语句?
if (condition){ //number1
if (condition){ //number2
action
}
else {
action;
}
}
else {
action
}
编辑:这是我的实际代码:
if ($s == 5){ //which award is won
$id_raw = $wpdb->get_var("SELECT user_ID FROM ".$wpdb->prefix."award".$award." WHERE user_ID='".$p_uid."'"); //check to see if user has already won this award
if($id_raw==''){ // if he/she didnt make entry saying they did
$wpdb->query("INSERT INTO ".$wpdb->prefix."award1 (user_ID, isTold) VALUES(".$p_uid.", 'false') ") or die(mysql_error());
wp_delete_post( $pid, true );
}
}
else{
cp_points('voteitup_user_up', $uid, get_option('cp_module_voteitup_user_up'), $pid);
cp_points('voteitup_author_up', $p_uid, get_option('cp_module_voteitup_author_up'), serialize(array($pid,$uid)));
}

只是猜测你在这里真正想做什么,因为你的id_raw = ''
是一个无意义的条件而且问题不明确:
$insert = $id == 5 && !$wpdb->get_var("SELECT user_ID FROM ".$wpdb->prefix."award".$award." WHERE user_ID='".$p_uid."'");
if ($insert) {
$wpdb->query("INSERT INTO ".$wpdb->prefix."award1 (user_ID, isTold) VALUES(".$p_uid.", 'false') ") or die(mysql_error());
wp_delete_post( $pid, true );
} else {
cp_points('voteitup_user_up', $uid, get_option('cp_module_voteitup_user_up'), $pid);
cp_points('voteitup_author_up', $p_uid, get_option('cp_module_voteitup_author_up'), serialize(array($pid,$uid)));
}
希望这会给你一个想法。

为什么不结合前两个if语句?你需要在那里做其他事吗?
if (condition1 && condition2) {
action
}
else {
action
}
