php - How to read values from MultiCheckbox in Zend -

-

I have a problem with this Zend form element, how can I read the element status of the multicachebox? 

  $ type = new Zend_Form_Element_MultiCheckbox ('typer'); $ Type- & gt; SetLabel ('type'); $ Type- & gt; AddMultiopts (array ('1' => 1 type ',' 2 '=> 2'););

Thanks for the support!

retrieve it with GetValue () 

  $ Type- & gt; GetValue ();

This would be an array with only that element that was checked.

i.e. 

  & lt; Input type = "checkbox" name = "type []" id = "campaign_id" value = "1" /> & Lt; Input type = "checkbox" name = "type []" id = "campaign_id" value = "2" />

Such an array will return (if both are checked) 

  Array ([0] => 1 [1] = 2)

If asked only the checkbox 2 was checked then the array 

  Aare ([0] => 2)

getValue () will return NULL if no checkboxes are checked

Obfuscating Python code? -

I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
