PHP - Print any variable easily

2011-10-28T05:05:00.000+03:00

You often need to print some PHP variable right into the HTML code, but the variable is out of your current scope. Familiar problem, isn't it?

Here is a bright solution: PHP function that prints any global variable:



function print_var($var = 'domain', $url = '')

{

  global $$var, $$$var;

  if ($url != '') 

    echo("<a href=\"$url\">${$var}</a>"); 

  else 

    echo(${$var});

}

Moreover, you can pass some URL as a second parameter, and your variable becomes a clicable link :)

Some examples:



<?php  print_var('page')?>

<?php  print_var('domain', '/') ?>

<?php  print_var('software', '/download/') ?>

<?php  print_var('author', 'http://www.site.com') ?>

Wordpress + Custom Scripts = Error 404

2011-10-16T16:24:00.000+03:00

Wordpress is the most popular CMS in the world. Many sites are powered by Wordpress, plugins almost for every need are available. But...

If you decide to add some custom web scripts or other CMS to the domain where Wordpress is already installed, you'll get a problem with Error Handling. Wordpress shows Error 404 (File not found) for any URL that is not a part of Wordpress system!

Moreover, Wordpress changes standard error pages to its own ones. So if an error occurs outside Wordpress environment, the error message appears in Wordpress style anyway!

This can be fixed using .htaccess settings. At first you should exclude work folders form RewriteMode redirections. Add the following line into .htaccess file in the root of your site:

RewriteEngine On
RewriteBase /wordpress/
RewriteRule ^index\.php$ - [L]
RewriteCond %{REQUEST_URI} !^/(folder1|folder2)/
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule . /wordpress /index.php [L]

Then you should disable custom error page, at least in folders of your scripts. Add the following line to .htaccess files in your script folders. You can add this line to the root file as well, but sometimes it doesn't work:

ErrorDocument 404 default

This is enough if Wordpress is installed into a folder. But if Wordpress is installed into the root of the site, the solution may not work depending on CMS version and installed theme. Most probably you will need to fix some files manually to disable 404 error handling. The core is located in class-wp.php file:

function handle_404() {
...
$wp_query->set_404();
status_header( 404 );
...
}

BTW, Wordpress in the root of the site is not a best practice...

Function IsValidEmail for Delphi

2011-07-04T07:43:00.002+03:00

It's hard to believe, but there is no standard function in Delphi to verify the email address. Also there is no native RegExp support. So I have to create own routine for email verification. It is not fully RFC compatible (there is no support for user@[10.20.30.40] and John Dow <a@b.c>) but is good enough for 99% of end-user programs.

//------------------------------------------------------------------------------
// Verifies is the given string valid email address or not. Domain names without
// dots (user@localhost) are acceptable if AllowRootDomain is True.

function IsValidEmail(const Value: string; AllowRootDomain: Boolean = False): Boolean;

//-------------------------------------

  function _Verify(const S: string): Boolean;
  var
    i: Integer;
  begin
    Result := False;
    for i := 1 to Length(S) do
      if not (S[i] in ['a'..'z' ,'A'..'Z', '0'..'9', '_', '-', '.']) then Exit;
    Result := True;
  end;{Internal _Verify}

//-------------------------------------

var
  i: Integer;
  User, Domain: string;
begin
  Result:= False;
// @ is must, but not first
  i := Pos('@', Value);
  if i < 2 then Exit;

  User := Copy(Value, 1, i - 1);
  if User = '' then Exit;

  Domain := Copy(Value, i + 1, MaxInt);
  if Domain = '' then Exit;

  if not AllowRootDomain then
  begin
  // Dot is must, but not first
    i := Pos('.', Domain);
    if i < 2 then Exit;
  end;

// Dot should not be first and the last
  if (Domain[1] = '.') or (Domain[Length(Domain)] = '.') then Exit;

// Verify each char of User and Domain
  Result:= _Verify(User) and _Verify(Domain);
end;

P.S. Does anybody use Delphi in 2011? :)

Created just for fun - Auto Mute

2009-11-02T13:04:00.006+02:00

I've created small software utility to make notebooks silent when it's turning on or is waking up from a sleep mode. So the computer becomes quiet even if you forgot to turn the sound off in previous session. Very useful if you have small children or are trying to work in public places, on conferences for example.

Actually, this is my old idea of software for people who have small children, but nobody wants to make such tool for years. So if you want to have something you cannot buy, do it by yourself :)

Hope this program will be helpful to many people. If you need additional feature or know how to improve this sound control software let me know.
