Simple to use Get Excerpts with Thumbnail plugin uses meta data of wordpress post, to retrieve thumbnail image. It also uses another plug-in named Content Extract by Rob Shumann, to retrieve excerpt from POST. You need install Content Extract plugin before start working with this plugin.

Inspite of having found numerous plugins to get excerpts along with thumbnail images in Wordpress plugin directory. I have written this plugin to reduce number of requests that are made to MySQL database while fetching data.

== Installation ==
Install Content Extract by Rob Shumann, before installing this plugin.
The plugin is simple to install:

1. Download the zip file, from wordpress plugin directory
2. Unpack the zip.
3. Extract zip file and upload directory present in zip file to the `wp-content/plugins` directory on your WordPress installation.
4. Activate plugin
5. Go to Settings -> Get Excerpt with Thumbnail page, to change configuration for the plug-in.

Configuration of Plug-in:

Goto Settings -> Get Excerpt With Thumbnail link in your wordpress admin page.
Following four elements need to be configured.
1) Thumbnail CSS Class -> this is .css class name to be used by this plug-in. By default, CSS class name is displayed as ‘imgstyle’, change this to your desired class name and make sure it is defined in .css file of your wordpress theme.
2) More Text -> link that appears next to excerpt to read full post.
3) Post Length -> Inspite of reading entire post to retrieve excerpt, plugin just reads number of characters entered by you in this field.
Note: Once an excerpt is generated by this plugin, it will be stored in excerpt field of your wordpress post.
4) Excerpt Length -> Length of excerpt to be displayed.
Note: Always make suer Post Length is greater than or equal to Excerpt Length.

Sample usage of this plugin:

while (have_posts()) {
the_post();
$data = getExcerptsWithThumbnail();
echo $data['post_thumbnail'] . ‘<h5>’ . $data['post_title'] . ‘</h5>’ . $data['post_excerpt'] ;
}

In above code snippet, you can see getExcerptsWithThumbnail() function returns an array.
code snippet uses <h5> tag to display title of the post, you can use any of the style you want, for the presentation of thumbnail image along with excerpt.

Get Excerpt with Thumbnail plugin just gives data, presentation of this data on theme pages is left to theme developer.

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.

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

To find out various concurrent programs associated with certain responsibility, following query will be useful.

select user_concurrent_program_name  from fnd_concurrent_programs_tl
where concurrent_program_id in (
select request_unit_id from fnd_request_group_units
where request_group_id in (
select request_group_id from fnd_request_groups where request_group_id in (
select request_group_id from fnd_responsibility where responsibility_key like ‘%ORACLE_INVENTORY%’)
));

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);
}
