TLF Bugs

I recently ran into a couple hard to diagnose TLF bugs, this might help save someone else a couple days of debugging time..

1] Redraw bug when using Linked Containers

2] Embedded fonts break if your program uses spark text containers

Speed up Flash Builder 4 compile times

1] If your project has multiple application targets, everytime the project rebuilds it rebuilds every application in your project. So if you have 4 targets, things can get slow fast. To remedy this, right click your project, click Properties, goto Flex Applications, and remove the applications your not currently running. Set the remaining application as default.

2] If your project has many files, when the project rebuilds it will copy them into the bin-debug folder which could take a long time, Right click your project, click Properties, click Flex Compiler, uncheck Copy non-embedded files to output folder. You will have to copy files to the bin-debug folder manually if any assets are required.

Pagination pagelinks PHP algorithm

If you are making a pagination with adjacent links and are trying to figure out how to find out which number the links should start at, the algorithm below should help.

Case 1
Not enough pages, just show them all..
if (totalPages < adjacent*2)
[1]-2-3-4

Case 2
Almost at start, just start showing from beginning
true when currentPage - adjacent < 1
1-[2]-3-4-5-6 ..
starti = 1

Case 3
Almost reached the end, start showing till reached end
true when currentPage + adjacent > totalPages-1
.. 6-7-8-9-[10]-11
starti = currentPage-adjacent*2+(totalPages-currentPage)

Case 4
Not close to end or start, show even number of adjacent links on each side
true when none of above cases match
.. 2-3-[4]-5-6 ..
starti = currentPage-adjacent;


if ($this->totalPages <= $this->adjacent*2) {
$starti = 1;
$endi = $this->totalPages;
}
else if ($this->currentPage - $this->adjacent < 1) {
$starti = 1;
$endi = $this->adjacent*2;
}
else if ($this->currentPage + $this->adjacent > $this->totalPages-1) {
$starti = $this->currentPage - $this->adjacent*2 + ($this->totalPages-$this->currentPage);
$endi = $this->totalPages;
}
else {
$starti = $this->currentPage - $this->adjacent;
$endi = $this->currentPage + $this->adjacent;
}


Flash Builder Beta 2

Adobe... who's stupid idea was it to force users to "upgrade" to Beta 2?

If you've been getting this error trying to load a style SWF:
VerifyError: Error #1014: Class mx.modules::ModuleBase could not be found.

at flash.display::MovieClip/nextFrame()
at mx.core::FlexModuleFactory/deferredNextFrame()[E:\dev\gumbo_beta2\frameworks\projects\framework\src\mx\core\FlexModuleFactory.as:574]

at mx.core::FlexModuleFactory/moduleCompleteHandler()[E:\dev\gumbo_beta2\frameworks\projects\framework\src\mx\core\FlexModuleFactory.as:652]

1] right click the project that contains the CSS file your compiling
2] goto Flex Build Path
3] Change framework linkage to merged
4] Click on the Flex 4.0.0 build path and Remove it
5] Click Add Flex SDK to readd it
6] Click ok to exit and re-clean your project

Hopefully this will fix your compiler bug.

Making a whos online script with Zend_Session_SaveHandler_DbTable

1] fetch rows from zend_session table where modifiedtime > time()-900
2] unserialize the data column using this function

function DecodeSession($sess_string)
{
// save current session data
// and flush $_SESSION array
$old = $_SESSION;
$_SESSION = array();

// try to decode passed string
$ret = session_decode($sess_string);
if (!$ret) {
// if passed string is not session data,
// retrieve saved (old) session data
// and return false
$_SESSION = array();
$_SESSION = $old;

return false;
}

// save decoded session data to sess_array
// and flush $_SESSION array
$sess_array = $_SESSION;
$_SESSION = array();

// restore old session data
$_SESSION = $old;

// return decoded session data
return $sess_array;
}

3] print out the username which should be stored in the session data, it'll look
something like
echo $session['data']['Namespace']['user']['username'];
