Catching variables

[Perfidus]

Hi there!

 

I have a bunch of vars like tipo1, tipo2, tipo3, tipo4 sent via POST...

The number may vary depending on user choice.

I would like to recover the vars in an array, but the way I'm trying is not working:

 

for($i=0;$i<$numberoftipos;$i++)
{
$tipo2=array($tipo[$i]);
echo $tipo2[$i]."<br>";
}

 

It echoes nothing...

Any hints?

Changing var names is not possible, I can't rename them like tipo[] because they come from multiple radio buttons, so they need differente names or only 1 will be able to be checked in a big list !!!

I would like to recover the vars in an array

 

What does that meen? There already in an array, the $_POST array. Explain exactly what your trying to achive.

 

Also, its easiest to loop through posted vars with a foreach(). eg;

 

<?php

  foreach($_POST as $k => $v) {
    echo "$k = $v<br />";
  }

?>

In the $_POST array there are too many vars, not only those who have the name tipo1, tipo2, tipo3, tipo4.

Those are the ones >I want to recover inside an array called $tipo2

You meen a recursiv function?

Just rename them to tipo[] and give them individual values of 1, 2, 3 and 4.

 

$tipo = $_POST['tipo'];

if(count($tipo) > 0){
   foreach($tipo AS $tipos){
   echo $tipos . "<br>\n";
   }
}

As I said, I can't rename them like tipo[] because they come from multiple radio buttons, so they need differente names or only 1 will be able to be checked in a big form !!!

I'm sending lot's of vars using whatevername[] from the forms to automatically create the arrays, but with the radio buttons, I can't use the tipo[] name because then is impossible to check more than 1 option.

Oops, guess I didn't catch that. Why don't you just do something like:

 

for($i=1;$i<=4;$i++){
echo $_POST['tipo' . $i];
}

gonna try, this is maybe what I was asking for...

Well, it doesn't work, but it should be something like this...

Just want to invoke them knowing that their names are composed by the word 'tipo' and a number...
