Understanding how to use preprocessor in Drupal can be very confusing. In this post we will explore how to achieve adding a variable to a node template file using the preprocessor hook (function). The first thing we need to create is the preprocessor function that has mandatory elements so that Drupal can see the hook (function) when called.

Drupal website is displaying 500 error or a blank page

Sometimes when moving a Drupal directory it will not copy all the files into the new directory. This can be caused by the way you copy the files and/or the permissions of the files on the webserver. I had a Drupal site that would work perfectly in its original directory but if I copied the Drupal 7 software into another directory I would get a 500 error or the browser would go blank. It took me a while to find the .htaccess was not copying into the new directory. As soon as I manually copied it across the website worked perfectly.

Small smtp email server client on desktop

I need a small smtp client so I could send emails from my Drupal development machine. By using the package msmtp-mta this can be achieved. Firstly install the software, in this example Ubuntu will be used but from what I can see all Unix flavours have this package

~$  sudo apt-get install msmtp-mta

After it is installed then configuration is needed this can be by creating a file called msmtprc and adding some configuration.

After installing it we need to create a configuration file for it. Create a new file by opening vim or nano in the terminal

~$ sudo vim /etc/msmtprc

Then add the configuration you need to access your email smtp server. In this example we will use the Google smtp servers.

Git commands that we all need to remember

Git is fantastic but there are times when you need to find that odd command because you have stuffed something up. Here are some I use on those occasions, firstly open the terminal and navigate to the root directory of the Git repo.

You didn't want to commit that

~$ git reset --soft HEAD~1

I want to remove the second last commit

~$ git rebase -i HEAD~2

The master branch commits have moved ahead from my-current-branch when I first branched off

~$ git checkout my-current-branch
~$ git rebase master

I need to see the changes before I commit

~$ git diff [filename]

I need to see a users commits in the logs

~$ git log --author="username"

I want see what was committed

Git merge branch and commit individual files

Merging two Git branches and then commiting each merge file seperaterly looks easy except while in a merge Git will not let you do it. This howto will explain one way how to do it. Firstly go to the terminal window and move to the Git directory that you want to merge.  In this example I am going to merge the large-branch-to-be-merge into the master. Check out the master branch or the branch you want to merge like the example below.

~$ git checkout master
~$ git branch

The next step is to do the merge so that your wonderful new set of code will make the amazing changes to the software.

Drupal development environment

As a Drupal click monkey I came away from Drupalcon Sydney determined that I was going to contribute back to Drupal in some way. The big push in the community is to help with core development and the issue cues if you are able. But to a new Drupaler it is like looking at a mountain you need to climb and the only tool you have is a toothpick. I was listening to a Drupalise.me podcast that was discussing contributing back to the community, what I found interesting about the conversation was when they started to contribute it was like looking at a mountain to climb and only having a toothpick. I was not alone it seems.

Embed views into a Drupal node.tpl

On a project early this year I found the need to add a view of images between the content type body and comments. I looked at context module as I have used it before. But on reflection the website was very small and I didn't see the need to install an extra module for this small job.  After some research I found the function views_embed_views this allows the developer to add a view to a tpl file using code. This post shows you how you can do it for yourself. Firstly create a view that has a view page and view block and call the view anything you like. I have called mine views_embed_view (not very imagitive I know).

PHP how to increase memory

Increase memory using php.ini file

Increasing your memory for the Drupal Framework is important as this allows the application to work faster and then deliver the content to the user giving faster access to the content that you are providing. There are two ways to do this, if you have access to your php.ini file on your web server find the line that says the following.

memory_limit = 16M  ;

Most service providers will only allocate the default amount of 16 megabytes of ram. If  you change it to 64 megabytes of ram this will fix the issue.
