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";
?>
Source Code
Here is the complete source code. Simply cut and paste this into a valid HTML document
and give it a try.
<?php
$LDAP_NAME[0] = "Netscape Net Center";
$LDAP_SERVER[0] = "memberdir.netscape.com";
$LDAP_ROOT_DN[0] = "ou=member_directory,o=netcenter.com";
$LDAP_NAME[1] = "Bigfoot";
$LDAP_SERVER[1] = "ldap.bigfoot.com";
$LDAP_ROOT_DN[1] = "";
//If no server chosen set it to 0
if(!$SERVER_ID)
$SERVER_ID=0;
//Create Query
$ldap_query = "cn=$common";
//Connect to LDAP
$connect_id = ldap_connect($LDAP_SERVER[$SERVER_ID]);
if($connect_id)
{
//Authenticate
$bind_id = ldap_bind($connect_id);
//Perform Search
$search_id = ldap_search($connect_id, $LDAP_ROOT_DN[$SERVER_ID], $ldap_query);
//Assign Result Set to an Array
$result_array = ldap_get_entries($connect_id, $search_id);
}
else
{
//Echo Connection Error
echo "Could not connect to LDAP server: $LDAP_SERVER[$SERVER_ID]";
}
//Sort results if search was successful
if($result_array)
{
for($i=0; $i<count($result_array); $i++)
{
$format_array[$i][0] = strtolower($result_array[$i]["cn"][0]);
$format_array[$i][1] = $result_array[$i]["dn"];
$format_array[$i][2] = strtolower($result_array[$i]["givenname"][0]);
$format_array[$i][3] = strtolower($result_array[$i]["sn"][0]);
$format_array[$i][4] = strtolower($result_array[$i]["mail"][0]);
}
//Sort array
sort($format_array, "SORT_STRING");
for($i=0; $i<count($format_array); $i++)
{
$cn = $format_array[$i][0];
$dn = $format_array[$i][1];
$fname = ucwords($format_array[$i][2]);
$lname = ucwords($format_array[$i][3]);
$email = $format_array[$i][4];
if($dn && $fname && $lname && $email)
{
$result_list .= "<A HREF=\"ldap://$LDAP_SERVER[$SERVER_ID]/$dn\">$fname $lname</A>";
$result_list .= " <<A HREF=\"mailto:$email\">$email</A>><BR>\n";
}
elseif($dn && $cn && $email)
{
$result_list .= "<A HREF=\"ldap://$LDAP_SERVER[$SERVER_ID]/$dn\">$cn</A>";
$result_list .= " <<A HREF=\"mailto:$email\">$email</A>><BR>\n";
}
}
}
else
{
echo "Result set empty for query: $ldap_query";
}
//Close Connection
ldap_close($connect_id);
//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>";
//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";
}
