Incorrect if/else statement?

[golden14]

I'm working on passing a lot of variables from Flash to PHP, and then back to Flash again.  It works correctly when I run this:

 

<?php

for ($i=1; $i<31; $i++) {
  ${'rg1tName'.$i}=$_POST['rg1_'.$i];

  if($i>1){
    echo "&rg1_".$i. "=".${'rg1tName'.$i};
  }

  else { 
    echo "rg1_".$i. "=".${'rg1tName'.$i};
  }

}
?>

 

But when I add more into the if/else statements (which I need to do), it doesn't work. 

 

<?php

for ($i=1; $i<31; $i++) {
  ${'rg1tName'.$i}=$_POST['rg1_'.$i];
  ${'rg2tName'.$i}=$_POST['rg2_'.$i];

  if($i>1){
    echo "&rg1_".$i. "=".${'rg1tName'.$i};
    echo "&rg2_".$i. "=".${'rg2tName'.$i};
  }

  else { 
    echo "rg1_".$i. "=".${'rg1tName'.$i};
    echo "rg2_".$i. "=".${'rg2tName'.$i};
  }

}
?>

 

Using trial and error and commenting out different sections of the code and changing it (both the AS3 and the PHP), it seems like the problem is in the PHP in the echoing sections.  Based on what you see here, is there something noticeably wrong?  Thanks!

I don't see anything obviously wrong (apart from the unusual use of variables instead of an array for ${'rg1tName'.$i}.  That makes me nervous, but I guess it ought to work )

 

Is it possible that the url is too long?

[golden14]

It's not pulling from a URL, Flash is storing text box strings in variables using the URLVariables method in AS3.  I have 4 groups of variables, each with a different prefix (rg1, rg2, rg3 and rg4).  It works no problem when I try it with just one.  But when I add that second grouping in there, it will POST it without giving an error but the echo sections will give an error.

 

Thanks anyway though!

Can't help very much, but just make sure your double checking all your variable names, etc..

 

Thorough spell check I suppose.

 

Sorry I can't be of much help.

I'm not that much with flash, but from what I read, Flash need each variable in it's own line

 

<?php

for ($i=1; $i<31; $i++) {
  ${'rg1tName'.$i}=$_POST['rg1_'.$i] . "\n";
  ${'rg2tName'.$i}=$_POST['rg2_'.$i];

  if($i>1){
    echo "&rg1_".$i. "=".${'rg1tName'.$i} . "\n";
    echo "&rg2_".$i. "=".${'rg2tName'.$i};
  }

  else { 
    echo "rg1_".$i. "=".${'rg1tName'.$i} . "\n";
    echo "rg2_".$i. "=".${'rg2tName'.$i};
  }

}
?>

 

just add "\n" at the end of each variable except the last one, so if you have three or four

 

// 3 variables example
    echo "rg1_".$i. "=".${'rg1tName'.$i} . "\n";
    echo "rg2_".$i. "=".${'rg2tName'.$i} . "\n";
    echo "rg3_".$i. "=".${'rg3tName'.$i};

// 4 variables example
    echo "rg1_".$i. "=".${'rg1tName'.$i} . "\n";
    echo "rg2_".$i. "=".${'rg2tName'.$i} . "\n";
    echo "rg3_".$i. "=".${'rg3tName'.$i} . "\n";
    echo "rg4_".$i. "=".${'rg4tName'.$i};

 

and so on

The echo sections give an error?  What is the error?

[btherl]

Oh.. I just thought about your code's logic.  It doesn't make sense.  You can do it like this:

 

$sep = '';
for ($i=1; $i<31; $i++) {
  ${'rg1tName'.$i}=$_POST['rg1_'.$i];
  ${'rg2tName'.$i}=$_POST['rg2_'.$i];

  echo $sep . "rg1_".$i. "=".${'rg1tName'.$i};
  $sep = '&';  
  echo $sep . "rg2_".$i. "=".${'rg2tName'.$i};

}

 

$sep will be blank for the first variable only, ensuring that you get a & in front of every subsequent variable.
