To obtain the value of the arguments of the function

Laycee last edited by
Used in the templates where I need to connect the Pope as a marker to the function:
```
Main_Registry::setVar('disclaimer', true);
```
In the first specimen, I want to determine which text for the cap is to be removed from the base. How do I get the first argument from another method without changing the function setVar without adding it? func_get_args()?
I've been through this. reflection - new ReflectionParameter(array('Main_Registry', 'setVar'), 0); - but it reverts to the argument, not the point of argument in challenging the function.

Dry the parameters. Here's the option:

class Main_Registry
{
public static function setVar($param , $bool = true){
    if($bool){
        return self::getResult($param);
    }
}

private static function getResult($param){
    $data = [
        'disclaimer' =&gt; "value 1",
        'main' =&gt; "value 2",
        'common' =&gt; "value 3",
    ];
    return ($data[$param] ? $data[$param] : "param {$param} not exist");
}

}
echo(Main_Registry::setVar('disclaimer', true)."\n");

echo(Main_Registry::setVar('main', true)."\n");

echo(Main_Registry::setVar('empty', true)."\n");

value 1 value 2 param empty not exist

I can only do that, maybe not the best.If it's 0 and 1 and you have to pick all zeroes, it's the same thing they're worth 0.select product_id, avail from (select product_id, avail, sum(avail) as sum from t1 group by product_id) as tmp where sum = 0

You can do that with help. http://php.net/manual/ru/functions.anonymous.php The code is presented below:function get($a) { return function($b) use (&$a) { $a = $b + $a; return $a; }; } $a = get(5); echo $a(3)."\n"; echo $a(2)."\n"; DEMO: https://ideone.com/8or9aG

Try to add everything in the loop and then you represent it, try like this://declaras una variable que funcionara como bandera para validar y almacenar el antiguo id $id_Area=-1; //declaras una variable que almacenara los resultados $total=0; //variable bandera en falso $bandera = false; while($row=$resultado->fetch_assoc()) { if ($id_Area != $row['ID_Area'] && $id_Area != -1) $bandera =true; $PrecioGrupo=$PrecioGrupo + $row['PrecioTotalOP']; ?> <tr> <td><?php echo $row['ID_Area'];?></td> <td><?php echo $row['Desc_Area'];?></td> <td><?php echo $row['OP'];?></td> <td><?php echo $row['Cliente'];?></td> <td><?php echo $row['CantidadOP'];?></td> <td><?php echo number_format($row['VolumenOP'],4,"." , ",");?></td> <td><?php echo "$". "". number_format($row['PrecioTotalOP'],0, " " , ",");?></td> </tr> <?php //comparamos si el nuevo id es igual al viejo && verificamos que para evitar insertar en la primera instacia if ($bandera) { ?> <tr style="width: 100%;"> <td style="text-align: right; width: 100%;"><?php echo $total;?></td> </tr> <?php //ponemos la bandera en falso nuevamente $bandera= false; //reiniciamos la variable total $total = 0; }else{ //dentro del ciclo y en cada vueltas vas sumando cuando no se cumpla la condicion $total = $total + number_format($row['PrecioTotalOP'],0, " " , ","); } //alamacenamos el valor del id para compararlo con la proxima vuelta $id_Area = $row['ID_Area']; } ?> I hope it serves you and the xD mark

In order to be able to verify any value during the compilation, this value should be used in the appropriate context. The argument of the function does not apply to this context. And if a non-type sympathetic function is performed, it will be possible to do so. The truth of synthaxis will be different:#include <cstdlib> template <class T, size_t N> class Vect { public: typedef unsigned int size_type; T coord[N] = {}; template <size_type I> constexpr T& get() { static_assert(I < N); return coord[I]; } }; int main() { Vect<int, 10> v; v.get<9>(); // OK v.get<10>(); // Ошибка компиляции } Such a function is already available in the standard library when used std::get ♪ std::array♪

That's how it works:#include <stdio.h> void swap(int * p, int * q) { int tmp = *p; *p = *q; *q = tmp; } int main() { int a = 5, b = 3; int * pa = &a, * pb = &b; printf("%d -- %d\n",a,b); swap(pa,pb); printf("%d -- %d\n",a,b); } (See. http://ideone.com/lkEusl ) Look what's transferred to the function and what changes in it.They're transferring. indicatorsand change values in the respective memory siteswhich they point.UpdateWell, if you want to change the signs, use the signs on them:void swap(int ** p, int ** q) { int *tmp = *p; *p = *q; *q = tmp; } challenge, respectively:swap(&pa,&pb);

Look, I'm gonna put you on an iterative algorithm that I did some time ago.public bool EsPrimo(int num) { int raiz = Math.Sqrt(num); int cont = 2; bool esDivisible= false; bool esPrimo = false; if(num == 2) { esPrimo = true; } else { while(cont <= raíz && esDivisible == false) { if(num % cont == 0) { esDivisible = true; } cont++; } } if(esDivisible == false) { esPrimo = true; } return esPrimo; } An example of a call would be for example to know the cousins between 2 and 100for(int i = 2; i<= 100; i++) { if(esPrimo(i)) { Console.WriteLine(i.TiString() + " es primo); } }

if (isset($_POST["userfile"]))// Вот это уже неверно. Во-первых, не isset, а !empty надо так как задано поле всегда если оно присутствует в форме, а во-вторых не $_POST, а сразу файлы смотрите. $_FILES['userfile']['error']==0 && !empty($_FILES['userfile']['tmp_name'])

Well, cycling is what I understand. Don't resign and take your own data and run with them, and you'll see the result on paper. First substation -2 gives cycling in case whilebegin write('Введите значение x '); read(x); // -2 y:=-5*x+13; 23 if y>0 then // ок прошли дальше begin write('Введите значение шага преращения '); read(d); end; while y>0 do // до сих пор значение 23 пошли по циклу и зациклились begin x:=x+d; y:=-5*x+13; end; write(y) end. If you don't change the cycle, you don't need it for a condition. ifThe honest logic of your code is not clear at all.Well, the first time you checked, there was a condition, and if it didn't, what's supposed to happen?What do you have to do with this little and incomprehensible program?

By boolean indexing:If you want to get values that are DIFERENT to the filter, you have to use the expression !=that will exclude from your DataFrame the data that contain the value to compare.In your case, df2 = df[df['code'] != '005759']that will result in you: code quest 0 005756 Age group 1 005756 Age group 2 005756 Age group 3 005756 Liking 4 005758 Liking 8 005760 Liking 9 005756 Age group EDITATE: As you have changed the question, I edit to include your new requirement.In the same way, if you want to obtain only the values that are determined in another column, the expression should be ==, so it would remain like this: df2 = df[df['quest'] == 'Liking'] and the result would be this: code quest 3 005756 Liking 4 005758 Liking 8 005760 Liking

The date specified on the screen is to detect whether or not the working date of the DB side calendar referenced in AJAX, and whether the reference failed.A $.ajax connection test example using Deferred. ) .Deferred https://techblog.yahoo.co.jp/programming/jquery-deferred/ Look at it.$(function(){ var d = proc_a(); d.done(function(data, textStatus){ //ok console.log("ok:"+textStatus); console.log(data); }); d.fail(function(data, textStatus){ //error console.log("error:"+textStatus); console.log(data); }); function proc_a(){ var dp_a = new $.Deferred(); $.ajax({ type: "GET", url: "test.php", data: "hoge=piyo" }).done(function(data, textStatus, jqXHR){ //done dp_a.resolve(data, textStatus, jqXHR); }).fail(function(data, textStatus, jqXHR){ //fail dp_a.reject("error", textStatus, jqXHR); }).always(function(data, textStatus, jqXHR){ //done、fail どちらでも処理を行うとき }); return dp_a; } }); In addition, if the error caused by the DB is fail, you may call reject,resolve as follows:if (data[0] != 0) { errno = "err#014"; dp_a.reject(errno, textStatus, jqXHR);//fail }else{ dp_a.resolve(data, textStatus, jqXHR);//done } If you only determine the connection error, $.ajax uses Deferred (may be using Promise) internally, so you can write it as follows. $(function(){ $.ajax({ type: "GET", url: "test.php", data: "hoge=piyo" }).done(function(data, textStatus, jqXHR){ //ok console.log("ok:"+jqXHR.status); console.log(data); }).fail(function(data, textStatus, jqXHR){ //error console.log("error:"+jqXHR); }); }); The previous $.ajax callback (deprecated success:, error:) example.$(function(){ var d = proc_a(); d.done(function(data, textStatus){ //ok console.log("ok:"+textStatus); console.log(data); }); d.fail(function(data, textStatus){ //error console.log("error:"+textStatus); console.log(data); }); function proc_a(){ var dp_a = new $.Deferred(); $.ajax({ type: "GET", url: "test.php", data: "hoge=piyo", success:function(data, textStatus, jqXHR){ //done dp_a.resolve(data, textStatus, jqXHR); }, error:function(data, textStatus, jqXHR){ //fail dp_a.reject("error", textStatus, jqXHR); } }); return dp_a; } });

(Even if you leave the first half of the code, it will be useful to a lot of people, so you can cut it carefully.I would like to narrow down to the next story. )What you can experience is related to "asynchronous processing". There are many questions related to the Japanese stack overflow. )NCMBQueryThat’s because it’s prepared on Nifty Cloud, and I don’t use it myself, but the important thing is that the API is executed asynchronously.[b()の中にて] (あなたのアプリ)済んだら、これ{(objects, error ) in...//1...}しといてな (NCMB)よっしゃ(と言って「これ」をどっかに仕舞い込んだら、一旦処理を終了する) [b()から戻った直後] (あなたのアプリ)[まだ「済んだら」のタイミングが来る前にprint(self.id) //2を実行] -> 検索は終わっていないので、print(self.id)は「これ」が実行される前の値 [その後もまだ設定されていないself.idを使おうとするが...] [その後の未来のどこか、いつしか検索が終わった...] (NCMB)検索が終わったんで「これ」実行しとくわな -> //1のprint(self.id)が実行される [せっかくself.idに値を入れたものの誰も使うものがない...] Where to use breakpoints, etc.print(self.id)If you follow the execution, you should know that it will be executed in the above order. (e.g.)print("#1",self.id),print("#2",self.id)Comment )In order to deal with this, you will need the same idea as "Handling valid variables only within the delegate" that was somewhere in the thread.[1] Set the value to the instance variable in the completion handler and tell the user by updating the UI[2] Call the method to use the result in the completion handlerIn addition, [3] You may receive a complete handler for your method as a parameter and call it from the completion handler (NCMB ry), but it will be higher than 1 level, so if you rewrite your code with the [2] policy, it will look like this.@IBAction func a(sender: UIBarButtonItem) { b() //b()を呼び出したら何もせずに処理を終了する、完了した時の処理は別メソッドに任せる } func b() { // user1クラスを検索するNCMBQueryを作成 let query = NCMBQuery(className:"xxx") // データストアでの検索を行う query.findObjectsInBackgroundWithBlock{(objects, error ) in if error != nil { // 検索に失敗した場合の処理 }else{ // 検索に成功した場合の処理 self.id = objects.count print(self.id) //1 //検索に成功して受け取った値は必ず検索の完了ハンドラーの中で使う //処理がやや複雑なら別メソッドにするとわかりやすい doSomethingWith(self.id) } } } //b()の中でfindObjectsInBackgroundWithBlockが完了した時に呼ぶ処理は別メソッドに外出しする func doSomethingWith(id: Int) { print(self.id) // 2 // 画像をNSDataに変換 let fileName = "image\(id).png" let pngData = NSData(data: UIImagePNGRepresentation(self.displayImage.image!)!) let file = NCMBFile.fileWithName(fileName, data: pngData) as! NCMBFile // ファイルストアへ画像のアップロード file.saveInBackgroundWithBlock({ (error: NSError!) -> Void in if error != nil { // 保存失敗時の処理 } else { // 保存成功時の処理 } }) } I think that the trick to use asynchronous processing is "this" when done, but it may have difficult to understand.
