php - Magento static blocks disappear on homepage when query parameters present -

-

i'm quite new magento , i'm trying understand what's happeing static blocks on homepage of 1 of our clients (http://www.coveops.com). when query parameters passed (like ?utm_source...), static blocks disappears.

see http://www.coveops.com/?asdf vs http://www.coveops.com/ in between slider , bottom tripplet gone.

there many things causing this. first step figure out how content being rendered.

  1. log in magento admin backend
  2. go system->configuration
  3. scroll bottom , click advanced->developer
  4. in dropdown menu on top-left, select store view loading on homepage
  5. expand "debug" section, uncheck "use website", , set "profiler", "template path hints", , "add block names hints" yes

now when reload http://www.coveops.com (or dev server instead), should see red highlight around each block displaying information on how block rendered.

one piece of information path template file being rendered, example:

frontend/base/default/template/page/html/breadcrumbs.phtml

you can find file starting in app/design directory.

the other piece of information available there class name of block that's calling template file, example:

mage_page_block_html_breadcrumbs

these class names follow format:

namespace_modulename_block_path_to_blockname

so above example found in:

app/code/core/mage/page/block/html/breadcrumbs.php

once you've identified block , template in filesystem, can read code , reasons why block wouldn't load when parameters present in url. ?asdf being taken argument method in block, , it's causing method change output, or output nothing.

another place might in admin backend, under cms->pages->manage content, or cms->static blocks.

java - Copying object fields -

what best way of copying classes when need have 2 independent variables? have simple class: public class myclass { boolean = false; string b= "not empty"; } do need make method : assign(myclass data ) { a= data.a; b= data.b; } is there automatic method copy (duplicate) objects in java? do need make method : pretty close. instead of making method, should make constructor. such constructors called copy constructor , , create them this: myclass(myclass data) { = data.a; b = data.b; } and create copy of instance, use constructor this: myclass obj1 = new myclass(); myclass obj2 = new myclass(obj1); copy constructor can tedious : using copy constructor create deep-copy can tedious, when class has mutable fields. in case, assignment create copy of reference, , not object itself. have create copy of fields (if want deep copy). can go recursive. a better way create deep copy serialize , deserialize object. why not use clone()? ...

i have function processes , stores lot of data in , returns results vector of class. amount of data stored in function tremendous , want clear storage memory of function after finished job. necessary (does function automatically clear memory) or should clear memory function? update: vector<customers> process(char* const *filename, vector<int> id) { vector<customers> list_of_customers; (perform actions) return list_of_customers; } variables defined locally within function automatically released @ end of function scope. destructors objects called, should free memory allocated objects (if objects coded correctly). example of such object std::vector . anything you've allocated new must have corresponding delete release storage. try avoid doing own allocation , use raii instead, i.e. containers or smart pointers.
