angularjs ng-pattern regex for 4 digits and 2 decimal

I am trying to create a Regex for a number with maximum 4 digits and if the input has decimal it has to have 2 digits – .20 and not .1.
tried:

ng-pattern="/^[0-9]+(.[0-9]{1,2})?$/" //fail for 666666, .10, .1

Examples for valid inputs:

100.10
100
3000.10

Example for invalid:

10000 //has more then 4 digits before decimal
100.1 //has only 1 digit after decimal
.10 //has no digits before decimal

Thanks for any help.

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality - development

Using PHP and MySQL data to generate PDF letters like in MS Word mailmerge functionality I would really like to know if there is a way like MS Word mailmerge functionality that can be done using PHP and Mysql data. Like i have address data in MySQL (suppose 10 numbers) and through PHP i want to insert that address data in a pre-defined letter head area. And it will automatically generate 10 different letters with same content but different address in PDF. Can it be done? Any start up point will be helpful. As I am working on Laravel so any snippet of that sort will also be useful. Thanks in advance. from Laravel Questions and Answers https://laravelquestions.com/php/using-php-and-mysql-data-to-generate-pdf-letters-like-in-ms-word-mailmerge-functionality/ via Lzo Media

Angular.js ng-click with mouse middle button

I’m using angular 1.6.4, I have the following element: Text What I need is the element to be a regular link and call trackJobClick every time is clicked. Everything is working fine when you click it with the left button or ctrl (or cmd) + left button, but the function is not being called when I use my middle button (wheel). When I click using the wheel the link opens in a new tab (thats correct) but I also need to execute the function. Have been googling for a while but can’t find any solution, is there any easy way? Do I need to use a directive? I found https://github.com/thiagofaleiro/ng-middle-click/ but can’t make it work. Thanks in advance!

Using Intervention package to compress images. My images are not being compressed, still the same size - development

Using Intervention package to compress images. My images are not being compressed, still the same size I’m using this package http://image.intervention.io/getting_started/installation to compress my images that’s uploaded to my server. However the images are not being compressed. First I installed the Intervention package by putting this in my terminal: composer require intervention/image Then I added this at the top of my controller: use InterventionImageImageManagerStatic as Image; Then I added the encode to minify the image Image::make(request()->file(‘img’))->encode(‘jpg’, 1); It’s not minifying the image. It’s still the same size. <?php namespace AppHttpControllers; use InterventionImageImageManagerStatic as Image; use IlluminateSupportFacadesStorage; use IlluminateHttpRequest; class UploadsController extends Controller { public function store() { // Get image $img = request()->file('img'); // Mini...
