code1:
when the select statement is outside the function
post works

code2:
when the select statement is inside the function
post does not work

-------------
both code1 and code2 show a drop down select menu



I am using php+sqlserver 2005
<?php
//does not echo post
require_once('inc/common.php');
function displayProductFoldersC2($selected,$column) {
  echo'<select name="$column">';
    $sql = "SELECT distinct $column FROM rtrns where $column !='' ";
    foreach(dbfetcharray($sql) as $p) {
      if($p["$column"] == $selected) {
        echo '<option SELECTED value="' . $p["$column"] .'">' . $p["$column"] . '</option>';        
      }
      else {
        echo '<option value="' . $p["$column"] .'">' . $p["$column"] . '</option>';  
      }
    }
  echo "</selected>";
}  
$printable=$_POST[printable];
echo "<br>printable is $printable";
?>
<form action="#">
<?displayProductFoldersC2('Other','printable');?>
<input type=submit value=Submit>
</form>

Open in new window

<?php
//will echo post
require_once('inc/common.php');
function displayProductFoldersC2($selected,$column) {
  //echo'<select name="$column">';
    $sql = "SELECT distinct $column FROM rtrns where $column !='' ";
    foreach(dbfetcharray($sql) as $p) {
      if($p["$column"] == $selected) {
        echo '<option SELECTED value="' . $p["$column"] .'">' . $p["$column"] . '</option>';        
      }
      else {
        echo '<option value="' . $p["$column"] .'">' . $p["$column"] . '</option>';  
      }
    }
//  echo "</selected>";
}  
$printable=$_POST[printable];
echo "<br>printable is $printable";
?>
<form action="#">
<select name="printable">
<?displayProductFoldersC2('Other','printable');?>
</select>
<input type=submit value=Submit>
</form>

You don't say what doesn't work, but the following line is problematic:

  echo'<select name="$column">';

Because you're using single quotes, it won't do variable substitution.

Try:


  echo "<select name=\"$column\">";

It's just a typo, you wrote </selected> instead of </select>. The output of the echo should be visible in the html source in both cases, it is just not rendered in the browser because the <select> is not closed.

Good point - I missed the typo.  You'll need to do the quotes as well to get the correct name for the select field, though.

You need to declare post method or use $_GET[]
<form method="post" action="#">

One more hint: if your database can contain any string, use htmlspecialchars() to escape possible html tags in the output coming from the DB.
