zend framework2 - ZF2 select populate with AJAX -


Hello, I have three dropdowns, the first one is filled in my controller, the second is required to populate with the parameters in the Amazon.

One third and the third one is required when my form validates all the fields, it prints down the error in both the drop downdown. The input is not found in the hessstack

This is my AJAX call 

  $ ("# department_id") .change (function () {$ .ajax ({type: "POST ", Url:" & lt ;? php echo $ this-> url ('zfcadmin / getprovinces')>? ", Data:" Dept = "+ $ (this) .val (), success: Function (msg) {$ ("# province_id") .HTML (msg);}}}}};   
 This is my controller, am I doing any help wrong?  
  public function getProvincesByIDAction () {$ request = $ this- & gt; GetRequest (); $ Response = $ this-> getResponse (); If ($ request-> isPost ()) {$ response- & gt; Set StatusCode (200); $ CodDpto = $ request & gt; getPost ('department'); $ Data = $ this- & gt; Receivable () - & gt; GetProvinces ($ codDpto); $ Buffer = "& lt; option value = '' & gt; Selequen Uña provincia & lt; / option & gt;"; Forex Currency ($ prov $ $ as proof) {$ Buffer. = & lt; & Lt; & Lt; EOT & lt; Option value = '{$ prov- & gt; codProv} '& gt; {$ Prov-> Name} & lt; / Option & gt; EOT; } $ Response- & gt; Set content ($ buffer); $ Headers = $ response- & gt; GetHeaders (); } Returns $ Reaction; }   
 Any help?  
 Thanks   
 
 
 This server side is created when you submit the form This means that the value posted in the  value_options  statement for each selected element will not be (optionally loaded by AJAX)  
 error then "no input Was found in grass covered "can be thought of as" the option you chose was not an option in the selected element " 
 To validate the posted prices you must ensure that you add these options  before  validation and population on the server side (i.e. first  $ form-> set data ($ request- & gt; getPost ()) ) When the form is posted.

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
