The requirement came when we are developing a theme for our site SearchAndhra.com, where in we need to display latest posts belongs to a specific category, in our home page and also in single post page. After checking various plugins available for WordPress we coded this plugin.

The main motive behind coding this plugin is to reduce number of queries fired against MySQL database, while listing titles of latest posts.

List Latest Posts Titles plugin uses only one query per call, to retrieve titles of latest posts belongs to a particular category.

You can download and install this List Latest Posts Titles plugin from WordPress Plugin Directory.

Post your comments if you require any further information regarding this plugin, we are ready to help you out.

We can split a string into substrings using PL/SQL built in functions SUBSTR(), INSTR() and LENGTH() together.

Follwing code snippets helps you in splitting a string into substrings.

Snippet to split string into pieces:::

CREATE OR REPLACE FUNCTION func_str_split(str_to_split IN OUT VARCHAR2
,str_delimiter IN VARCHAR2) RETURN VARCHAR2
IS
t_pos NUMBER;
t_len NUMBER;
t_strlen NUMBER;
t_strresult VARCHAR2(2000);
BEGIN
t_strresult := NULL;
IF str_to_split IS NOT NULL THEN
t_len := LENGTH(str_delimiter);
t_strlen := LENGTH(str_to_split);
t_pos := INSTR(str_to_split,str_delimiter);
IF t_pos > 0 THEN
t_strresult := SUBSTR(str_to_split,1,t_pos-1);
str_to_split := SUBSTR(str_to_split,t_pos+t_len,t_strlen);
ELSE
t_strresult := str_to_split;
str_to_split := NULL;
END IF;
END IF;
RETURN t_strresult;
END func_str_split;

Use following procedure to call above function:::

CREATE OR REPLACE PROCEDURE proc_str_split(str_to_split IN OUT VARCHAR2
,str_delimiter IN VARCHAR2)
IS
declare

END proc_str_split;

select
fg.request_group_name,e.executable_name,responsibility_key,user_concurrent_program_name
from fnd_responsibility r,
fnd_concurrent_programs_tl p,
fnd_request_group_units u,
fnd_request_groups fg,
fnd_executables e,
fnd_concurrent_programs fcp
where r.request_group_id=u.request_group_id
and u.request_group_id = fg.request_group_id
and u.request_unit_id = p.concurrent_program_id
and fcp.executable_id = e.executable_id
and user_concurrent_program_name like ‘%Period close value summary%’
and fcp.concurrent_program_id = p.concurrent_program_id

Open any file as shown in the below snippet, and read data and pass it to gzencode() function.

If the file to be gzip is of larger size, read file in chunks to avoid memory errors, while reading file.

More info on gzip can be found at PHP Manual in http://php.net

Tremendous compressing achieved with following snippet.
function gzipSitemap($fileIndex)
{
 $file_to_gzip = “readme.txt”; //any type of file
        $gz_dest_file = “readme.txt.gz”;
 $fh = fopen($file_to_gzip, ‘r’) or die(“Can’t read file”);
 $fp = fopen($gz_dest_file, “w”) or die(“Can’t create .gz file”);
    while($theData = fread($fh, 5000))
 {
  $gzdata = gzencode($theData, 9);
  fwrite($fp, $gzdata);
 }
    fclose($fp);
    fclose($fh);
}
