They gave me some tasks over a huge site realized with Magento.
I use Netbeans with Xdebug to debug (I'm on lubuntu oneiric btw) and I'm finding myself quite fine with all my tasks.
It happened to me to face a task concerning a class redeclaration and I lost a lot of time in finding the right file to change.
Just to learn how to do it correctly:
the task was to change the meta keywords, starting from a code like
<meta name="keywords" content="<?php echo htmlspecialchars($this->getKeywords()) ?>" />
With Netbeans debugger I can easily open the file containing getKeywords() which has:
public function getKeywords()
{
if (empty($this->_data['keywords'])) {
$this->_data['keywords'] = Mage::getStoreConfig('design/head/default_keywords');
}
return $this->_data['keywords'];
}
Now I couldn't find an easy way to go on through debugging in both cases :(
In particular my case is that $this->_data['keywords'] is not empty on the page I had to correct ..
so how can I easily know how this object is created and in particular who fills _data['keywords']?
It took me long time to find the right file by myself.
I'm not so expert in debugging, so maybe I could do it with netbeans w/ xdebug, but I cannot figure it out.
Thanks
open up terminal and
grep 'setKeywords(' app/code/ -rsn
this will reveal you the locations where this variable is set or used
grep -ri "Keywords" * | grep -v cache
'-r' means recursive
'-i' means case insensitive
'*' means any file name
'| grep -v cache' means strip out any references into the cache directory
You could temporarily create the method:
public function setKeywords($s) {
echo sprintf('<pre>%s</pre>', print_r(debug_backtrace(), true));
exit;
}
Add this code to same class that has getKeywords() so that when someone adds data via this function, you will see the backtrace and figure out how it happened
