Fetching Dynamic Input Values?

[srarcade]

I have run into this problem many times. Each time I just try to find another way around it but this project, my only path is to find a solution to this problem. I want to retrieve values from dynamicly generated input. Heres a simple example:

if($mode==1)
{
	for($i=0;$i<5;$i++)
	{
		$value= /*????*/;
		echo "i=$i value=$value */<br>";
	}
}
else
{
	echo "<form method=POST action=\"vartest.php?mode=1\">";
	for($i=0;$i<5;$i++)
	{
		$name="input".$i;
		echo "$name:<input type=text name=$name><br>";
	}
	echo "<input type=submit value=OK></form>";
}

Any help greatly appreciated!

Try using a foreach loop through the $_POST array

I looked at the foreach statement and using arrays, and its quite foggy to me. I just cant quite seem to grasp onto that concept from what I read in the php manual.

for($n=1;$n<3;$n++)
{
     $name = "myvar".$n;

 echo "<input type=text name=$name>";
}

Just restating my main problem at hand- How would I retrieve the text value from the box with a name of $name when the name itself is generated through code?

I bet its a simple answer, it has to be! It dosnt look as complicated as it seems.

<?php
if ($_POST['submit']) {
  foreach ($_POST as $key => $value) {
    if ($key != 'submit') {
      echo "$key = $value <br>\n";
    }
  }
} else {
  echo "<form method=\"post\" action=\"$_SERVER['PHP_SELF']\">\n";
  for($i=0;$i<5;$i++) {
    echo "Input #$i: <input type=\"text\" name=\"input$i\"><br>\n";
  }
  echo "<input type=\"submit\" value=\"OK\"></form>";
}
?>
