Pass Array thru function

[felipe_lopes]

Hi Guys!

I have a form which create an array with its values when the form is sent:

<form name="form1" method="post" action="<? echo $_SERVER['PHP_SELF']; ?>?acao=login">
        <table width="100%" border="0" cellspacing="2" cellpadding="0" class="texto">
          <tr> 
            <td class="texto" width="37%"> 
              <div align="right">usuário:</div>
          </td>
            <td width="63%"> 
              <input type="text" name="var['usuario']" class="campos">
            </td>
        </tr>
        <tr> 
            <td width="37%" height="14"> 
              <div align="right">código:</div>
          </td>
            <td width="63%" height="14"> 
              <input type="text" name="var['codigo']" class="campos">
            </td>
        </tr>
      </table>
        <br>
      <table width="100%" border="0" cellspacing="0" cellpadding="0" class="texto">
        <tr>
          <td>
              <div align="center" class="texto"> 
                <input type="submit" name="submit" value="validar"> <a href="main.php?abrir=registrar">registrar</a>
              </div>			
          </td>
        </tr>
      </table>
</form>

Now I made a function to put the values of this array into DB:

function acao($acao, $var){
	global $table;

switch($acao){

	case "registrar":

		if(($var['usuario'] == "") || ($var['senha'] == "") || ($var['email'] == "")){

			return 1;
			break;

		}elseif($var['senha'] != $var['senha2']){

			return 2;
			break;

		}elseif($var['email'] != $var['email2']){

			return 3;
			break;

		}elseif(strlen($var['usuario'] ) < 3 || strlen($var['senha'] ) < 3){

			return 4;
			break;

		}

		$codigo = rand(1000, 9999);

		$senha = crypt($var['senha'], $var['senha']);

		//verificando se usuário já existe
		$sql = "SELECT * FROM $table WHERE usuario = $var[usuario]";
		$result = mysql_query($sql) or die("Nao foi possivel executar query. " . mysql_error());

		if(mysql_num_rows($result) > 0){

			return 5;
			break;

		}

		//Adicionando dados
		$sql = "INSERT INTO $table (usuario, senha, email, codigo) VALUES (\"$var[usuario]\", \"$senha\", \"$var[email]\", \"$codigo\")";
		$result = mysql_query($sql) or die("Nao foi possivel executar query. " . mysql_error());

		//formando variaveis para e-mail
		$assunto = "Código de validação";
		$mensagem = "Usuário: $var[usuario]\n<br>Código: $codigo\n<br>";

		mail($var['email'], $assunto, $mensagem);

		return true;
		break;

...

My problem is that this function is returning "1", not "true" as it should...I do a "print_r($var)" and all variables are there in the array, but if I do a "print($var['usuario'])" it returns empty!

What's going on???

Thanx in advance

Your code says it will return 1 if the following is true:

$var['usuario'] == "") || ($var['senha'] == "") || ($var['email'] == ""

So it looks like you need to see which variable(s) are blank...

None of then is empty!

I had to change the way to pass the variables...Now I'm using globals....Not using array anymore as well

It is returning true. true==1 and false==0. My guess is that you're doing something equivalent to

if(acao($acao, $var)==1){...}

In that case, you're trying to compare the returned value with an integer. In order to do that, PHP has to cast both values into the same type. If the function returns 1 then no such recasting is needed. But in the case the function returns true, PHP casts true to 1 and so that test succeeds.

Similarly, if the test is

if(acao($acao, $var)==true){...}

and acao() returns 1, then true again gets cast to 1 and the test again succeeds.

Either return false instead of true (Unix convention: a zero return value indicates 'no problems', nonzero return value indicates 'problem #n'); or use === (check the type as well as the value) when doing the comparison.
