addrule
in [PEAR]

From: zia mohaddes on 18 May 2010 17:34 Hello everyone, I had a quick question regarding rules. I want to set the following rule for a question( let's say): question3 is required if (question1+ question2) <100. I am wondering if I could do something like this with addrule. I know addrule only takes Boolean values, but I am wondering if there is any way to perform arithmetic operations with addrule? Thank you kindly for your help in advance! regards, zia
From: Mark Steudel on 18 May 2010 17:44 Are you referring to using HTML_QuickForm package? If so you can use a formRule e.g. function checkQuestions( $fields ) { if( ( ( $fields['question1'] + $fields['question2'] ) < 100 ) && strlen( $fields['question3'] ) == 0 ) { $errors['question3'] = 'Question 3 is required if questions 1 and questions 2 add up to less than 100'; } return count( $errors ) > 0 ? $errors : true; } $form = new HTML_QuickForm( 'form' ); $form->addFormRule( 'checkQuestions' ); $form->addElement( 'text', 'question1', 'Q1: ' ); $form->addElement( 'text', 'question2', 'Q2: ' ); $form->addElement( 'text', 'question3', 'Q3: ' ); (double check my synxtax, but that's one way to do this) Mark On Tue, May 18, 2010 at 2:34 PM, zia mohaddes <zia.simab(a)gmail.com> wrote: > Hello everyone, > > I had a quick question regarding rules. > > I want to set the following rule for a question( let's say): > > question3 is required if (question1+ question2) <100. > I am wondering if I could do something like this with addrule.
