If you want to run/test oneliners in PHP on the command line you can use the -r option.
php -r 'echo "Hello World";'
Will simply output “Hello World” on the command line
I sometimes use this method to test regexp expressions
php -r 'echo preg_match("/^Test/", "This is a test");'
Here I check if $string starts with the string ‘Test’ (the answer is no).
Using onliners on the command line can sometimes be very handy
When disabling an element or option in a Zend_Form we use the function setAttrib() or, if multiple options, setAttribs(). These examples are made in Zend Framework 1.10
Disable a form element in the controller
$form = new Application_Form_MyForm();
$form->getElement('elementName')->setAttrib('disable', 'disable');
This will disable the whole ‘elementName’ element.
Disable option in a radio or select element
In declaration of element:
class Application_Form_MyForm extends Zend_Form {
...
$typeOfLap = new Zend_Form_Element_Radio('elementName');
$typeOfLap->setRequired(true)
->addMultiOptions(array(
'A' => 'Option A',
'B' => 'Option B'));
...
}
In controller
$form = new Application_Form_MyForm();
$form->getElement('elementName')->setAttrib('disable', array('A'));
This will disable option ‘Option A’. If you want to also disable ‘Option B’ you can add it to the disable array: array(‘A’, ‘B’). It works the same way with select elements
Setting a default value (‘CHECKED’) in Zend_Form_Element_Radio is done with the function setValue(). This is an example of how to to this in Zend Framework 1.10
...
$typeOfLap = new Zend_Form_Element_Radio('typeoflap');
$typeOfLap->setRequired(true)
->addFilter('StripTags')
->addFilter('StringTrim')
->setDecorators(array('ViewHelper'))
->addMultiOptions(array(
'Practice' => 'Practice',
'Qualifying' => 'Qualifying'))
->setValue('Practice');
...
As most things in Zend this is also very simple.
