[PHP] Multiple variables

[Morten Nielsen]

Hi,
I got a table, which contains a lot of text-boxes. Each textbox has a name:

Text1
Text2
Text3
etc.

Is it possible to check if they are all set using a for-loop?
I think of something like:

  for($i=1;$i10;$i++)
  {
 if(empty(Text+$i))
 {
do something...
 }
  }

regards,
Morten

The easiest approach would be to name your boxes like this:

  input name=text[1]
  input name=text[2]

and so on.

Then you can just loop through the $_REQUEST['text'] array when you're 
processing the form.

From my understanding of what you wrote:

foreach($textBoxArray as $tBox=$tVal){
if(empty($tVal)){
echo(Found empty textBox: $tBoxbr\n);
}
}

Read in manual about isset() and empty()

[PHP] multiple variables

[Ralph Jarvis]

Hi;

An obvious question for some, but I am stumped:

I want to use multiple optins in an if statement...

if(user($arbitraryVariable)==(1 or 2 or 3 or 4))

What would be the proper syntax for this?

Thanks

Hi!

 if(user($arbitraryVariable)==(1 or 2 or 3 or 4))
 What would be the proper syntax for this?

Here:

if((user($arbitraryVariable) = 1) and ($arbitraryVariable = 4) and
($arbitraryVariable == round($arbitraryVariable)))

In other cases, you'd have to write

if((user($arbitraryVariable)==1) or (user($arbitraryVariable)==2) or (...))

Cheers,

Kiko

or use something like this:

$array_values = array(1,2,3,4);
if (in_array(user($arbitraryVariable), $array_values)) {
// do your stuff
}

Greets,

Edward

Sometimes I find a switch to be the most efficient (and least typing) 
approach:

  switch(user($arbitraryVariable))
  {
  case 1:
  case 2:
  case 3:
  case 4:
 do whatever
 break;
  default:
 do the other thing
  }
