In our example, $ format_array is our new array, which contains the query results and is formatted for output. First, cycle every element in $ result_array and assign it to a two-dimensional array for sorting. At the same time, we use the strtolower () function to convert all values to lowercase letters. Next, we use PHP with LDAP
In our example, $ format_array is our new array, which contains the query results and is formatted for output. First, cycle every element in $ result_array and assign it to a two-dimensional array for sorting. At the same time, we use the strtolower () function to convert all values to lowercase letters.
Next, we use a function called sort () that comes with PHP to sort data. The first parameter is the array to be sorted, and the other is the sort type to be executed, which is defined by the PHP document. Because we sort strings, we use "SORT_STRING ".
Third, we loop through the formatted array and allocate it to an output character named $ result_list, which contains the HTML description. Note that the URL format of ldap is used in the hyperlink. The format example is similar to: HREF = "ldap: // ldap.domain.net/uid?dannie,dc=domain.net ".
Close connection
Now all our data is included in $ result_list. we can safely close the LDAP connection.
<? Php
// Close the connection
Ldap_close ($ connect_id );
Customize the HTML table on the search page
Finally, we need to customize the HTML table used for search, which is used to perform search for users.
// Customize the table
Echo "<CENTER> <FORM action = '" $ PHP_SELF "'method ='" GET "'> ";
Echo "Search in: <SELECT name = '" SERVER_ID "'>"; // loop to create the SELECT option for ($ I = 0; $ I <COUNT ($ LDAP_NAME ); <br $ I ++)> echo "<OPTION selected value = '" $ I "'> ". $ LDAP_NAME [$ I]. "</OPTION>"; echo "</SELECT>
";
Echo "Search for: <INPUT name = '" common "'type ='" text "'> ";
Echo "<INPUT name = '" lookup "'type ='" submit "'value = '" go "'>
";
Echo "(You can use * for wildcard searches, ex. * Stanley will find all Stanleys)
";
Echo "</FORM> </CENTER> ";
?>
In the code, $ PHP_SELF is a global constant representing the script page itself. The loop is used to create the SELECT option through our $ LDAP_NAME variable.
Display result
Now that all the work has been completed, we will print the result set. If No matching result is displayed, "No Results" is displayed.
<?> Php
// Display the result
If ($ result_list)
{
Echo "<CENTER> <TABLE border = '" 1 "'cellpadding ='" 10 "'cellspacing = '" 0 "'
BGCOLOR = "# FFFFEA" WIDTH = "450"> <TBODY> <TR> <TD> $ result_list </TD> </TR>
</TBODY> </TABLE> </CENTER> ";
}
Else
Echo "No Results ";
?>
Source code
The following is the complete source code. you just need to cut and paste it into an HTML document and try it.
