Passing created $vars outside of functns

[sherry]

Hello.

I have a library file of functions that are housed in say, a file called 'library_fcns.inc'.
Inside of this library file, there is a function that is to resolve the $HTTP_POST_VARS into their respective vars to use in the main program file.

The routine inside of the library file and is called via a 'require' statement in the main program by the statement 'require("library_fcns.inc") is:

function array_resolution($HTTP_POST_VARS)
{

// Resolving Array vars for use in other parts of program

foreach ( $HTTP_POST_VARS as $key=>$value )
{
if ( gettype( $value ) == "array" )
{
foreach ( $value as $two_dim_value )
print "$key == $two_dim_value<br>\n";

if ($key)
{
$$key = "$two_dim_value";
}
}
else
{
// This print statement is to print info to screen
print "$key == $value<BR>\n";
}
}
}

---

In addition to printing $$key to the screen, I want EACH $$key as the var to be passed from the function to the main program file for use in the rest of the routing; for example, after the 'require("...")' statement in the main program, I want to print the value of a selected $key of my choice. The only value that is printed is the last $$key which is the 'name' of the 'submit button' as '$Submit'.

How can I pass each $$key as it is resolved back to the main program to use wherever I want?

Thanks.
Sherry

variables created inside a function are only available inside the function...so each new variable you are creating with $$key is being lost when the function exits.
u could try &$key = "$two_dim_value";
" & " is used to reference external variables within a function..not sure if it can work backwards creating the new variable outside the function tho. let use know if it works

You can also use the static...
<?
function blblb($m)
{
static $xyz;
$xyz = $m..."what you want to do..."
}

$bmx = "value I put in var...";

blblb($bmx);

$var = $xyz "what i want to do...";
...
?>

Hello Andre' and thank you for responding.

I tried the following code:

<?php
function blblb($m)
{
static $xyz;
$xyz = $m;
echo "m is $m and xyz is $xyz<p>\n";
}

$bmx = "value I put in  var...";

blblb($bmx);

$var = "The value of xyz for the var variable is $xyz";

echo "$var";

?>

The 'echo "$var"; statement displayed everything except the $xyz variable, so I guess we need to try something else.

Thanks again.

Hello Warren and thanks for responding.

Using your suggestion, I tried the following as a test. Everything works fine and variable info is passed outside of the function, EXCEPT, the only var combo remembered (or passed outside of the function) was the very last var from $HTTP_POST_VARS.

Do you have any suggestions on how to possibly use some type of iteration to spit the vars out of the function as they are encountered so they can be used later?

Also, note -- the code below can be used directly. Just ignore the 'foreach' error message that appears when the page is loaded. It only exists because $HTTP_POST_VARS variable is empty until the 'submit button' is clicked.

<?php

$key1 = "";
$value1 = "";

function post_vars($HTTP_POST_VARS, &$key1, &$value1)
  {
echo "The form vars are... $HTTP_POST_VARS<P>";

foreach ( $HTTP_POST_VARS as $key=>$value )
  {
if ( gettype( $value ) == "array" )
   {
   foreach ( $value as $two_dim_value )
     print "$key == $two_dim_value<br>\n";

   if ($key)
     {
      $$key = "$two_dim_value";
     $key1 = "$key";
     $two_dim_value1 = "$two_dim_value";
     print "KEY#1 = $key1<br>";
     print "TWO DIM'L VALUE#1 = $two_dim_value1<p>";
     }
   }
else
  {
  print "$key == $value<BR>\n";
     $key1 = "$key";
     $value1 = "$value";
     print "KEY#1 = $key1<br>";
     print "VALUE#1 = $value1<p>";

  }
}
 }
?>


<?php

$plan[0]= "MAKE SELECTION";
$plan[1]= "PLAN#1";
$plan[2]= "PLAN#2";
$plan[3]= "PLAN#3";
$plan[4]= "PLAN#4";

$form_block="
<form METHOD=\"POST\" ACTION=\"$PHP_SELF\">
<INPUT type=\"hidden\" name=test1 Value=\"test1_val\">
<INPUT type=\"hidden\" name=test2 Value=\"test2_val\">
<INPUT type=\"hidden\" name=test3 Value=\"test3_val\">
     <SELECT NAME=\"test_plan[]\">
       <OPTION VALUE=\"$plan[0]\" SELECTED>MAKE SELECTION
       <OPTION VALUE=\"$plan[1]\">PLAN#1
       <OPTION VALUE=\"$plan[2]\">PLAN#2
       <OPTION VALUE=\"$plan[3]\">PLAN#3
       <OPTION VALUE=\"$plan[4]\">PLAN#4
       </SELECT><p>
Make your selection, then click button.<br>
<INPUT type=\"submit\" name=submit Value=\"Click Here\">
</form>
";

echo "$form_block";

post_vars($HTTP_POST_VARS, $key1, $value1);

echo "Key is $key1 and Value is $value1 OR Two Dim'l Value is $two_dim_value1...<p>"; 

?>

Let me know your thoughts.  I also look forward to thoughts from others as well.
Thanks.
