Phinx config for Symfony2

As you may know, you can also use a php file for your phinx config. Just replace the phinx.yml with phinx.php and it should work fine. I like to use phinx in my Symfony2 bundles, because it’s better to use in a vcs like GIT. Also you can do rollbacks, and add the migration scripts to your build script like ant.

Anyways, when using different environments, you probably have different database credentials. I put this little preg_match in the php file to parse the database config from parameters.yml. This phinx.php is located in the bundle, so for example /src/Acme/DemoBundle/phinx.php .. the migrations would then be placed in /src/Acme/DemoBundle/Migrations/ .. Just make sure the location to the parameters.yml is correct at the top of the script. You probably want to use relative paths because otherwise the path is still different in your environments. Your development VM may have different paths than your production server.


Prevent double clicks on table rows with click event and anchors

Suppose you have a table, for example to show users, and you want the table row to be clickable. If you click the row, you will go to a page that shows user information. Or maybe edit the user. But the last column of your row also has some action buttons that can delete the user, de-activate it, or whatever. So, for example, something like this:

Now, if you add a click event on the tr, when you click the button, both the button and click event will fire. To prevent this, I found this nice stackoverflow post about it. This answer suited my needs better, because I also had used font awesome icons for my anchors.

I did change it a bit however, because you already know the tr element when it’s being clicked on, right? So I ended up with this javascript code, and it seems to work.

So actually the credits go to Augusto, but I just wanted to make a note her, in case I ever forget. The tagline my external memory is for real you know. My internal memory is not always that reliable ;-)

Use Sublime Text to help you create doctrine Entities part two

In my previous post I wrote about a regexp search and replace to create Doctrine entities easily from a phpmyadmin CSV export. After that post I found myself checking my own website to copy and paste the regexp. Then I tried recording a macro in Sublime, but it turns out sublime doesn’t record search and replace actions.

Then I learnt about the feature to install packages to your sublime install, which has a really cool RegReplace package. Just follow the instructions on that page. I was a bit confused at point three, but turns out I had to go to Package Control: install package. You can go there by pressing cmd+shift+p and then type Package Control. It should appear in the list.

Then this superuser post helped me configuring the RegReplace package. It took me a while to figure out how to use extended back references. But I got it all working now. I use Sublime Text 2, so go to Preferences → Package Settings → Reg Replace → Settings – Default.


At the replacements section I added this:

Don’t forget to enable “extended_back_reference” at the end of this file.

Then I went to Preferences → Package Settings → Reg Replace → Commands – Default and added this at the end:

Now when I am in my editor and press cmd+shift+p I can just type “Doctrine” and my command shows up. Then it’ll convert the cvs formatted table heads to a nice doctrine entity.


Use Sublime Text to help you create doctrine Entities

I don’t know about you, but when working in a projects that already exists, I am afraid to let Symfony extract the entities for my project. I’d rather just define a new entity myself. To get started, Sublime Text is very useful in creating the entity with annotations. Here’s what I do.

First, in phpmyadmin I go to the table I want to create an entity for. I use browse, select the first record, and then export this to CSV. Export to screen, and make sure the headers are in the first row.

Copy the headers to your clipboard, and then paste them in sublime text. Then first replace the comma’d with newlines, which is easy .. just search for , and repalce with \n. Make sure you have the regex function enabled (that’s the .* button).

Now the magic trick so convert the rows with column names to an almost complete entity. Again use the search and replace.

Find What: ^\"(.*)\"$
Replace With: \/\*\*\n \* \@ORM\\Column\(name\=\"$1\", type\=\"\", nullable\=false\)\n \*/\nprivate \$\l\1\;\n


Now you should have something like this:

If course you can alter this any way you like.

Now copy this to your IDE of choice (PhpStorm probably, right?) and finish the details.

Show date in other timezone with correct locale

We want to show the date / time in the timezone of the user, but also in the right locale. Unfortunately, strftotime doesn’t seem available for the DateTime object. So I ended up with something like this… I assume you did setlocale somewhere else in your project to make sure PHP is in the right locale.


Forward incoming mail using Amazon Services and Lambda

In this post I’ll try to explain how I used Amazon to forward our incoming mail to an e-mail address like gmail.

Update 16 feb: Updated the lambda script thanks to Chris in the comments :-)

Next day update: Forwarding mime coded mails didn’t show up too well in my mail client. Of course I was testing with plaintext first ;-). Also I found this github page, describing pretty much the same as this post, although they still use S3 objects which I find redundant. I updated my Lambda script. It now sends a raw message, copying the Content-Type and Content-Transfer-Encoding headers from the original headers. This seems to display much better :-)

Use case

Say you have a domain specifically for e-mail campaigns. To setup this domain as a whitelabel domain in Sendgrid, or whatever third party you use, you must probably verify the send address. To do so, you must be able to receive mail.

Maintaining a mailserver is a pain in the ass though, with all those evil spammers around. So we happily leave that to companies who are must better in that. On the other hand, we don’t want to pay for each campaign just to receive this stupid verification link. Forwarding e-mail seems like a nice solution.

However, we found that the services at namecheap, which included e-mail forwarding, isn’t always that reliable. So we switched to Amazon for our DNS services. Wouldn’t it be nice to use Amazon to receive and handle our e-mail as well? Could Amazon simply forward e-mail?

Well, turns out it can forward e-mail, but not with a one-click install. Here’s how I did it.


I used SES for incoming e-mail (and eventually outgoing as well). SES pushes the mail to SNS. And SNS pushes the notification with a Lamda function to e-mail with a little javascript.

I found this post on the amazon forum, but this guy used a s3 bucket to pull the e-mail from. I don’t want to store the mail in a bucket; I want to forward it immediately.

So I changed the script to fetch the information from the SES message directly. After I had fixed the scripts, permissions, etc it turned out that SES doesn’t send the actual contents of the e-mail message to the lambda script. But if you push the message to SNS, then the SNS message does contain the contents. So therefore I push to SNS, and let SNS push to lambda.

Setup SES

SES is Amazons Simpel Email Service. It is able to send and receive mail. But you need to verify your domain first, as well as the Email addresses you are going to use. At first I thought I only needed to verify the e-mail address that I use in the FROM field, but if you are in sandbox mode, you will also need to add the TO address.

Just add it exactly the same way, by pushing the “Verify a new email address” button, and enter the e-mail address that will be receiving the forwarded mails. Of course you can also have your SES account un-sandboxed, but actually I like this extra layer of security.

After you verify your e-mail addresses, you have to setup the Email receiving part. You have to make sure that your domain is configured correctly to let Amazon receive the mail. If you use route53 (which I think you should), Amazon can configure this automatically for you.

When that’s all done, you can create a rule set to receive the mails. But first, we need to setup the lambda function, and then the SNS service.

Setup Lambda

The lambda function can be created in python, node.js and java. I already had a node.js script to start with, so I changed that a bit to fit my needs. Just go to the lambda section and follow directions on the screen until the part where you can ‘Create a Lambda function’.

In my case it first came up with a screen ‘Select blueprint’, but you can just skip that. Then fill in the name, description and runtime (Node.js). And then use this script, but change it a bit to fit your needs.

At handler I used index.handler, and at Role I used the basic execution role. You will need this role later on to add permissions.

Now you could run a test with SNS, but the example test data doesn’t contain an e-mail message, so this won’t work very well. It should not come up with any errors though.

The downside of this forward is that you cannot see the original “to” address in your e-mail client directly. It is sent in the X-Original-To header though, so you could use this to build a filter or something like that.

Setup SNS

Now go to the SNS service to create a Simple Notification Service. First you create a topic that you name ‘ForwardEmail’ or whatever you like.

Then on the navigation on the left you can click on “topics” which gives you an overview of the topics. Click on that geeky looking ARN name. Now you should be able to create a subscription for this topic.

Here you select AWS Lambda as protocol, and then select the endpoint you created in the previous step.

So now you have a notification service that forwards notifications to the lambda script. You should note that the lambda function is only suitable for e-mails though, so if you connect another Amazon service to this SNS things will probably break.

Setup SES again

Now back to the SES configuration again. Make sure both the forwardFrom and forwardTo address are verified at the “Email addresses” section.

Now create the rule set at Email Receiving.

I setup the first action as SNS, selecting my ForwardEmail SNS. Then as second action I added Stop Rule Set, but I’m note sure if this is mandatory.

Test your setup

When I was testing my Lambda script at the Lambda service section, I basically had two problems, after I weeded out all the bugs in my script. First I got an e-mail verification error, because I didn’t know I had to verify the receiving e-mail address as well.

Second, I received an error, something like this:

User arn:aws:sts::167718239101:assumed-role/lambda_basic_execution/awslambda_724_20160203104053770' is not authorized to perform ses:SendEmail' on resource `arn:aws:ses:us-west-2:167718239101:identity/'

Turns out that Amazon also has a very sophisticated permission management thing. To fix this, go to IAM under Services (Security & Identity). At the dashboard you can see that you have Roles, my dashboard says Roles: 1. Click on it and you will see an overview of your roles. Here you will also see lambda_basic_execution.

Click on it, and at Inline policies click on “Create Role Policy”. Then add this policy:

That’s it. At the service CloudWatch you should be able to see the logging of your lambda script. Also you should probably reduce the retention, because if you keep your logs forever I think Amazon will make you pay for it.

Hope this helps you. I am no Amazon expert whatsoever, so I’m afraid this is all I can tell you at the moment :-).

Samsung Xpress M2022W fix wifi problems

My mom was using her samsung m2022w printer for about 17 months when all of the sudden it just didn’t work anymore. I spent hours and hours trying to fix this and eventually succeeded.

Samsung xpress m2022w

Things I tried:

  • Update the firmware to it’s latest version. Be aware that you cannot change it back easily. I could not find older firmware versions on the samsung website.
  • Update the software of course.
  • Changed the location of the printer, because it said the signal was poor.
  • I took it home, because the router also recently changed, so I figured the new modem from the internet provider was just crappy.

In the end, as a last resort, I tried configuring the IP static one more time. I disabled the “auto IP” option, left it at DHCP (instead of BOOTP), and choose to enter my IP manually. Filled in all the details, and this time I got lucky and it connected to the network without any issues. By the way, to do this I had to connect the printer with the USB cable. Also disable Wi-Fi Direct because I don’t think the printer has two wlan radio’s on board.

I first changed these settings in the Easy Print Manager. The wifi wizard wasn’t working there, Windows would give an error telling me I should install the right software or something like that. But I was able to configure the network to be manually. Although it didn’t really feel like it was saving the configuration, but I checked by turning the printer off and on again. The settings were still there. Also now when I turned the printer on, the WPS button turned blue, without flashing, and stayed blue.

Now I could run the diagnostic tool. Here I updated all drivers, but on the bottom there is also an easy wifi setup tool thingy. At the version I used, I could also change the TCP/IP settings here. Just to be sure, I also configured the IP as static in here. To be sure it didn’t conflict, I used another static IP though, because I wasn’t sure which config would win: the one from Easy Print Manager, or the one using this wizard kind of setup.

I had used this wizard many times before, but when it was sending my configuration to the printer, that would just fail. This time it didn’t fail, it went right through, and I could finish the setup.

Finally I could also disconnect the USB. Opening up Easy Print Manager now showed the printer with it’s static IP, and I could print from notepad. Great!

So bottom line: use a static IP.

HP Laserjet 400 slow job processing

At the office, we got ourselves a nice HP Laserjet 400. Because it could do all things: print, fax, scan, and it should be OS X compatible too.


But when we wanted to print a document from our laptops, all connected to our gigabit LAN, it took ages before the printer finally started processing the job. So I installed some additional memory to the printer, which wasn’t too expensive anyways from eBay. Still no improvement. Some prints would come out fast, some prints didn’t. I thought it had something to do with processing the document to the right format for the printer. Isn’t that what PCL isn’t all about? Maybe the OS X drivers couldn’t talk to the laserjet in the most efficient way. Maybe the drivers aren’t that good after all.

Eventually I kind of gave up on the machine. My colleagues were already using our old laserjet 1320 anyways. The Laserjet 400 basically degraded to a really expensive scanner, at which it’s not very good either by the way.

Until one day extra people joined our team, and we moved the furniture around a bit in the office to create extra workspaces. This time I connected the printer through wifi, and now it seems that prints are coming through way faster.

So although I don’t understand why this is working better, just give it a try. It might work for you as well!

Midnight Commander os x terminal shift keys fix

Of course you are a command-line guru like me, but once in a while it’s just so much easier to use Midnight Commander. Especially when renaming files or directories, where you can just edit the name windows-style. Well, if your shift key works like it should that is.

I couldn’t bare that it wasn’t, so I did some digging and found out that os x term sends the wrong codes. I found this solution on superuser, but what to do with the other shift keys? I also found this article that looks outdated, but is still pretty cool. I ended up mapping F13 to shift F1, F14 to shift F2, etc. using the X11R6 xterm codes. That’s because in this bug report somebody said that SHIFT F6 should output ^[[17;2~ so that matches the xterm codes.

Eventually I mapped all my SHIFT F-keys (which I don’t use much anyways) like this.

OS X term keyboard mapping for Midnight Commander

jQuery Validation form valid event

I was using the jQuery Validation plugin in a project, but I couldn’t find a proper option that I could use to find out if the form indeed was completely valid. We wanted to show a message like “You’re almost done, just hit signup now and you can start right away!” when all fields in the form were valid. I guess it’s the call to action stuff that marketing guys really like.

Using a $(form).valid() inside the unhighlight would cause a too much recursion error, which actually makes sense. The form itself doesn’t seem to have an invalid state either, when I checked with firebug.

So in the end, all I could think of, was counting the number of valid inputs, and see if they were all valid. I must see, I only used input text and selectboxes. Beware that also hidden inputs will be counter if you use the input selector.

I left out all the other code, so, this is the piece of code that really matters.

You could also do it the opposite way, and count the error elements. I actually did this too, because another comforting text was required when the e-mail input was hit: don’t worry, we won’t sell your data! This actually seemed a bit harder because there were input field that didn’t have a error message. But, surprise surprise, the error element was placed anyways, it just didn’t contain any text.

Also, when you unhighlight, the element doesn’t go away, it just becomes invisible.

But well, if you want to fool around with it, this is the selector I came up with. Note that my error messages go into a feedback container, but I suppose you could just search on the class name as well.

It’s actually the :parent and :visible that does the trick. I wasn’t sure if I could combine them, but it seems to work. According to the jQuery document, :parent is the inverse of :empty.

So you could use this if you only want to show a messages when no more (visible) errors are there anymore, for example if you use the same space. This is a bit different than count the valid options, because if you have invalid options that don’t have an error message, and therefore don’t use space, it still may be nice to show some message.
