Create an LDAP Address Book Page 4

Make HTML Form for Search Interface

Finally, we get to the HTML output of the script. This set of code prints out the form that
is used for performing the searches.

<?php
//Make Form
echo "<CENTER><FORM ACTION="$PHP_SELF" METHOD="GET">";
echo "Search in:<SELECT NAME="SERVER_ID">";
//Loop Through and Create SELECT OPTIONs
for($i=0; $i<count($LDAP_NAME); $i++)
  echo "<OPTION VALUE="$i">".$LDAP_NAME[$i]."</OPTION>";
echo "</SELECT><BR>";
echo "Search for:<INPUT TYPE="text" NAME="common">";
echo "<INPUT TYPE="submit" NAME="lookup" VALUE="go"><BR>";
echo "(You can use * for wildcard searches, ex. * Stanley will find all Stanleys)<BR>";
echo "</FORM></CENTER>";
?>

The only portions of this code that is interpreted is $PHP_SELF which is a global
constant for the name of the script itself and the loop that creates the SELECT box from
our $LDAP_NAME variable.

Echo Results

Now that all of the work has been done, we print out the result set. If no results were
returned, a message is given stating the same.

<?php
//Echo Results
if($result_list)
  {
  echo "<CENTER><TABLE BORDER="1" CELLSPACING="0" CELLPADDING="10" 
        BGCOLOR="#FFFFEA" WIDTH="450"><TR><TD>$result_list</TD></TR>
        </TABLE></CENTER>";
  }
else
  echo "No Results";
?>

and give it a try.
