Reminder: Zend Framework Route Regex

If you want to make the route / optional

A note about the above regular expression. It uses one of the "expression syntax" which uses ?:
This means that every digit inside (?:) will NOT be group and outputted separately.

Consider this:

$t = 'archive/1234';
preg_match('#archive(?:/(\d+))?#', $t, $matches);
[0] => archive/1234
    [1] => 1234

Whereas without ?:

$t = 'archive/1234';
preg_match('#archive(/(\d+))?#', $t, $matches);
    [0] => archive/1234
    [1] => /1234
    [2] => 1234
notice that if you include ?: that the "/1234" did not get outputted.

Notes: Two usefull templating functionality in Zend Framework

If you do templates and use the Zend Framework there are 2 useful functionality that you can utilize (maybe there is more but I only looked at these two):




I am not going to explain anything about these two classes since it pretty well documented in ZF Docs but if you are a big template user who likes to mess with placeholders, the above functions would work great.

Tip: Retrieve your server url with Zend_View_Helper_ServerUrl

This helper is badly documented in the Zend Framework site.

Works as:
print $this->view->serverUrl();
// prints

Tip: Get MVC instance throughout the site

A very useful functionality of the Zend Framework:

If you want to retrieve the View instance from an Action plugin you can do something like:

    public function dispatchLoopShutdown()
        $layout = Zend_Layout::getMvcInstance();
        $view = $layout->getView();
        // now you can mess with the view object!!

Tip: search word in a file then print result

This will search for a whole word (-w) in a file, print the filename (-H) and print the line number (-n)
find . -exec grep -nwH 'searchString' {} \;

Notes: Eclipse method/function searching

Another thing I like about eclipse.

If you want to search for example a method/function name in PHP and want to look for its declaration and any occurrences of this method do this:

If its your first time running the search, setup the Working Set first by doing step 1:
Step 1.
option 1)
CTRL + H -> Scope section -> Click Choose -> Click New -> Select PHP -> Type a working set name -> choose your desired working set to search.

The step above will store your working set to search for for future searches.

option 2)
IF you dont want to bother with storing working sets. Right Click on your working set on your left panel -> Select Search

Step 2:
CTRL + H -> PHP Search (Tab) -> Search For: (Method name) option -> Limit to: (All occurences) option -> Then click Search button

A thing to note. If you are searching for a class name you need to change the "Search For" option to "Type" or your search will not work!

NOTES: allowEmpty

There is an "allowEmpty" parameter in the Zend framework form elements where if set to false (allowEmpty = false), it means that it will always validate the element and if the "required" parameter is also set to false.
