How to echo form values

Hi, I have a form like this in php on list.php

PHP Code:


		
			
echo " <form name=\"form1\" method=\"post\" action=\"sites.php\">";
$i = 1;
  while ($i <= 10){
 echo"<input type=\"text\" name=\"field$i\"><br>";
$i++;
}
echo "</form>";

in sites.php I have

PHP Code:


		
			
 $i = 1;
  while ($i <= 10){
echo"$field$i";
$i++;
}

The problem is that all I see is the numbers 1 through 10 in sites.php.
My question is how can I echo the variables passed by list.php?
Thanks in advance

First of all, this:

PHP Code:


		
			
 $i = 1;
     while ($i <= 10){
   echo"$field$i";
   $i++;
   }

should be this:

PHP Code:


		
			
 $i = 1;
     while ($i <= 10){
   echo"field$i";
   $i++;
   }

field should not have a dollar sign in front of it or else PHP will think it's a variable and try to retreive the value it stores.

Second, you are sending your form via post. Is register_globals on (which, I should add, isn't good for security: http://forums.devshed.com/t20525/s.html). If not, you'll have to access the variables from the $_POST array.

In list.php you should treat the textboxes as an array. If you want them to be named field but give multiple values, name the textboxes field[]. This will turn it into an array and when the data is passed to sites.php, you can find all your values located in the array $_POST['field'].

Remember, it is an array so you have to iterate it to get all the values. Below is both scripts modified to do just that:

Enjoy:

list.php

PHP Code:


		
			
<?php

echo " <form name=\"form1\" method=\"post\" action=\"sites.php\">";

$i = 1;

  while ($i <= 10){

echo"<input type=\"text\" name=\"field[]\"><br>";

$i++;

}

echo '<input type="submit" />';

echo "</form>";

?>

sites.php

PHP Code:


		
			
<?php

foreach ($_POST['field'] as $field_num => $field_value) {

        print "Field #$field_num : $field_value <br />\n";

}

?>
