I was not aware of MySQL support for regular expression using REGEXP operator. This post is to all people who might not aware of usage of regular expressions in MySQL.

MySQL has quite different syntax to handle it in sql query.It’s like this

SELECT * FROM tbl_name WHERE field_name REGEXP ‘[[:digit:]]{3}$’;

Explaination: It would select records where field value has mininum 3 digits( 0-9 ) and REGEXP is the reserved word.

similar query with some special character as regular expression pattern

SELECT * FROM tbl_name WHERE field_name REGEXP ‘[[.vertical-line.]][[.vertical-line.]][[:digit:]]{3}’ ;

Explaination: It would select records where field value has mininum 3 digits( 0-9 ), prefixed with ‘||’ .
exmple value : ‘||100′

You can find more details for the same under MySQL documentation : Regular Expressions section

As per requirement, I need to add a new field for my table with username initials. In this case, we have already 500 users, and their transaction records. I want to update records for existing user records. I got solution using mysql inbuilt function. Solution is like this

Table name: Users
Fields: userid, username, user_initial (newly added field)

username includes “firstname lastname” combination
i.e. “xyz pqr”, it should update record with initials “xp”

Query:
UPDATE Users set user_initial= concat( substring(username,1,1), substring(username, locate(‘ ‘,username)+1, 1) )

here, it wil take first letter of string and concate it with second initial, where for finding second initial it will first locate position of space in string and then get first letter of it using substring.

1. name of element
2. URI of an action that is called when update done
3. cols and rows to show editable area (textarea)
4. loadTextURL: The URI of an action that is called to display the text to edit.

example:

echo input_in_place_editor_tag(‘price’, ‘item/updateOrder?id=’.$id.’, array(‘size=>’5′, ‘maxlength’=>’10′, ‘highlightcolor’=>’#B0E0E6′,
‘loadTextURL’=>url_for(‘item/getURLValue?id=’.$id.’&type=price’)
));

Please note here, i have used ‘url_for’ here for loadTextURL because, i have faced problem of getting value, in case of your application is full ajax application, and it may contain different URL in address bar of browser. If your browser has some other url with sub modules and action, and that time specifying simple module/action will not work as it will search for that module/action according to url in browser (module in other module). To solve this problem, you have to make it independent of browser url and that can be done using ‘url_for’. We will get full URL using it so there is no chance of confusion with browser url during ajax call.

1.perldoc perlmodlib

It will show list of libraries which are part of perl installation and default installed.

2.perldoc perllocal

It will show list of libraries installed and which are not part of default libraries included at time of perl installation.

* assuming you are having root access on server. so can run commands on terminal.

You will get library name and path from error log (in case of internal server error)

Example:
I want to use XML::Writer library.
It’s located in /usr/local/lib/perl5/site_perl/5.8.9/XML/Writer.pm

Server Error like :

Can’t locate XML/Writer.pm in @INC (@INC contains: /usr/local/apache/perl

1. Get exact location of library.
command :
locate XML/Writer.pm

result :
/root/.cpan/build/XML-Writer-0.606-85Lgu7/Writer.pm
/root/.cpan/build/XML-Writer-0.606-85Lgu7/blib/lib/XML/Writer.pm
/usr/lib/perl5/vendor_perl/5.8.8/XML/Handler/CanonXMLWriter.pm
/usr/lib/perl5/vendor_perl/5.8.8/XML/Handler/XMLWriter.pm
/usr/local/lib/perl5/site_perl/5.8.9/XML/Writer.pm

2. Check the result of command select the path exactly matching with your library. Then include it’s parent directory to your file, so server will search for library in that directory also.

example: .pm ,.pl file

start.pm
use lib qw(/usr/local/lib/perl5/site_perl/5.8.9)
use XML::Writer;

3. Now, server will search “/usr/local/lib/perl5/site_perl/5.8.9″ directory also (including default @INC) to locate libraries, so it can find and locate particular library.

$encport =’443′;

if($_SERVER['SERVER_PORT'] !== $encport || $_SERVER['HTTPS'] !== “on”)
{
header(“Location: https://”.$_SERVER['SERVER_NAME'].$_SERVER['SCRIPT_NAME']);exit;
}

For this we have to do changes in following files

apps\frontend\config\app.yml – define the
modules and action files that are to be put to secure site

app.yml
all:
ssl:
insecure_host: one.mydomain.com
secure_host: secure.mydomain.com
#it can be same as insecure host

secure_actions:
- { module: register, action: add }
- { module: auth, action: login }
- { module: user, action: changepassword }

apps\frontend\config\filters.yml – add sslfilter

filters.yml
sslFilter:
class: sslFilter

apps\frontend\lib\sslFilter.class.php – library file for ssl

sslFilter.class.php

/**
 * Filter for redirecting to SSL for the pages that need it
 *
 * @author James McGlinn <james@mcglinn.org>
 * @version 2
 */
class sslFilter extends sfFilter
{
  /**
   * Execute filter
   *
   * @param FilterChain $filterChain The symfony filter chain
   */

  public function execute ($filterChain)
  {
    // Only execute this filter once
    if ($this->isFirstCall() && SF_ENVIRONMENT != 'dev') {

      // Array of modules/actions that require move to SSL
      $ssl_actions = sfConfig::get('app_ssl_secure_actions');
 
      if (empty($_SERVER['HTTPS']) && count($_POST) < 1) {

 
        // We're not using SSL and not POSTing data - check if we should be using SSL
        foreach ($ssl_actions as $action) {

          if ($this->getContext()->getModuleName() == $action['module'] && $this->getContext()->getActionName() == $action['action']) {

            $new_url = sprintf('https://%s%s', sfConfig::get('app_ssl_secure_host'), $_SERVER['REQUEST_URI']);
            header('Location: ' . $new_url);
            exit;
          }

        }
 
        // Using secure host when not required - not good
        if ($_SERVER['HTTP_HOST'] == sfConfig::get('app_ssl_secure_host')) {

          $new_url = sprintf('http://%s%s', sfConfig::get('app_ssl_insecure_host'), $_SERVER['REQUEST_URI']);
          header('Location: ' . $new_url);
          exit;
        }

      } elseif (!empty($_SERVER['HTTPS']) && count($_POST) < 1) {

 
        // We're using SSL and not posting data
        $dont_redirect = false;
        foreach ($ssl_actions as $action) {

          if ($this->getContext()->getModuleName() == $action['module'] && $this->getContext()->getActionName() == $action['action']) {

            $dont_redirect = true;
          }
        }
        if ($dont_redirect == false) {

          // Redirect
          $new_url = sprintf('http://%s%s', sfConfig::get('app_ssl_insecure_host'), $_SERVER['REQUEST_URI']);
          header('Location: ' . $new_url);
          exit;
        }

      }
    }
    // Next filter
    $filterChain->execute();
  }

}

I want to search on two different field of a table with multiple terms as a search string.

$c = new Criteria();
$c->addSelectColumn(MyTablePeer::MY_ID);

//get search term array
$txtSearchArr = split(‘ ‘,trim($txtSearch)); //whatever seperator

for($i=0;$i<count($txtSearchArr);$i++)
{

$criterion->getNewCriterion(MyTableTypesPeer::TYP_NAME, “%”.$txtSearchF.”%”,Criteria::LIKE));
$criterion->addOr($c->getNewCriterion(MyTableCategoryPeer::CAT_NO, “%”.$txtSearchF.”%”,Criteria::LIKE));

$c->addAnd($criterion);
}

The above will search in typename and categoryno for each terms and combination of each term in each field.

Example:

Table : TBL_EXM

Field_Id
Field_Tags( a comma separated field)

Query:
SELECT * FROM `TBL_EXM` ORDER BY (SUBSTRING_INDEX(`Field_Tags`, ‘,’ , 1))

It is having more combination and options. You can check in detail from here
