Re: [fw-general] Quick Question
THANK YOU SO MUCH COLIN AND EVERYONE THAT HELPED OUT. I looked into the issue it was exactly what Colin anticipated. My bootstrap was running two response dispatches. Hence the problem. I must have inserted this while i was still learning about the framework. [code] $response = self::$front->dispatch(); // first call self::sendResponse($response); self::$front->dispatch(); // second call [/code] It makes sense now. Thanks a mil Colin!!

I had an issue with pages being double rendered/hit twice for every request. Turned out to be this, because the browser was actually requesting the same url twice (once for the page, once for the image). -- Brenton Alker http://blog.tekerson.com/ signature.asc Description: OpenPGP digital signature
Re: [fw-general] Quick Question
Thanks Colin. But in my case i dont have a button linking directly to the component. The typical scenerio is, you submit the form, my controller processes it, and at the end sends all the values via email. For captcha, it render with the page loading. So there isnt any direct user action to the components so to speak.

Ah. Great, thanks for confirming that for me. In the mean time, I just
condensed that code into an iterator loop for simplicity.
-
$config = new Zend_Config_Ini('projectForms.ini', 'project form');
$subforms = array();
while($current = $config->project->form->current()) {
$subforms[$config->project->form->key()] =
new Zend_Form_SubForm($config->project->form->current());
$config->project->form->next();
}
$this->addSubForms($subforms);

Not currently, though it's something I'd like to change in an upcoming
version. If you want to see it sooner, extend Zend_Form and create a new
method for adding sub forms that does not require a Zend_Form object.

RE: [fw-general] quick question...
As Philip also says, this is done sometimes by SQL generators to make it easier on the person who developed the code for the SQL generator. It makes it easier because then they don't have to write code for the case of adding the first term to a WHERE clause. That is, if the SQL statement is assumed to contain the syntax "WHERE 1 = 1" by default, then any real conditions you specify can simply be appended to the WHERE clause with an AND operation. It shouldn't be a problem to have the extra 1=1 term, even though it seems inelegant and messy. SQL optimizers should be smart enough to factor out any operand of an AND expression that evaluates to TRUE for every row. "WHERE TRUE AND " is equivalent to "WHERE ". Similarly, a SQL optimizer should be able to factor out any operand of an OR expression that evaluates to FALSE for every row. "WHERE FALSE OR " is equivalent to "WHERE ". FWIW, Zend_Db_Select does not need to add the artificial 1=1 term! :-) If you specify no conditions in the WHERE clause, Zend_Db_Select simply omits that clause. Regards, Bill Karwin From: Adam Balgach [mailto:[EMAIL PROTECTED] Sent: Tuesday, May 01, 2007 1:59 PM To: Zend Mailing List Subject: [fw-general] quick question... has the group ever heard of using 1=1 in the where clause of a SQL statement?

Thanks, A.

Thanks, A. Many people do that for situations where they are unsure if there will be a where clause or not. So, to make things simpler, they just use 1=1 and tack on "AND ..." to the end. As far as I know, there isn't any harm in it. It makes coding SQL statements easier if there is a change there will be no conditional checks ( a grab all ). -- Philip [EMAIL PROTECTED] http://www.gpcentre.net/
