[B]isset[/B] check that exist a variable, but do not Necessarily a value useful or it that I wait.

I have a form with two [B]input[/B] to upload [B]multiple[/B] files, with ‘size’ the [B]submit[/B] button, more the function [B]isset[/B] and ‘name’ with some echos …
When I press the [B]send[/B] button; without being charged anything, It show the echos, or results

[B]isset ()[/B] is something “useless” in the case of [B]$ _FILES[/B] because this array exist, but that does not mean you’ve uploaded something.

@NogDogJan 27.2016 — To lazy to look at your code ( ? ), but you're probably better off with either [FONT=Courier New][B][COLOR="#A52A2A"]!empty($_FILES)[/COLOR][/B][/FONT] or [FONT=Courier New][B][COLOR="#A52A2A"]count($_FILES)[/COLOR][/B][/FONT] .

@ApolexNetauthorJan 27.2016 — [B][/B]? It is working out just by pressing [B]send[/B], It show the results. :/

[B]Look it:[/B]

[B][COLOR="#0000CD"]PAGE HERE[/COLOR][/B]

[B][COLOR="#0000CD"]CODE HERE[/COLOR][/B]

I tried this and either:

[code=php]
if(isset($_POST["submit"])) {

//valida que el formulario se envio

// cualquiera de las 2 formas

if($_FILES['accs']['name'] == "") {

echo "no envió nada.";
}

if($_FILES['accs']['size'] == 0) {
echo "no envió nada.";
}

// puedes guardar una variable para manejar errores

if ($errores == "")
{
Ejecuto

}
}
else
{
echo "no envió el formulario";
}
[/code]

What could I do? ?

@ApolexNetauthorJan 28.2016 — I tried with a while, and It get me a result similar to that I want. But with errors. ?

while($res = $_FILES['archivos1']['name'][0] <= $_FILES['archivos1']($insert))

$dn = ("cAAn$id");

$dn1 = chunk_split($dn, 1, '.');

{

echo $dn1;

}

There is any something similar for I get it to run, Not without uploading something previously before of send.

@NogDogJan 28.2016 — [code=php]$_FILES['archivos']['name'][0]
$_FILES['archivos']['name'][1]
$_FILES['archivos']['name'][2]
// etc....
[/code]

@ApolexNetauthorJan 28.2016 — You made me realize the error, and I created a [B]for[/B] to change of the numero. Thanks as always, you deserves much money.

[code=php]
$_FILES['archivos1']['name'][$i]
$_FILES['archivos']['name'][$i]
[/code]
