How to get complete current URL for Cakephp 3.x

Below are few steps described to get URL inside Cakephp 3.x controller as well as view file. You can get full URL and base URL and current URL inside Controller.

The very first thing is to include Router in your Controller as below:

use Cake\Routing\Router;

public function urls()
{
    echo "<div style=''>";
    echo "Current URL=" . Router::url(null, true);
    echo "<BR>Current URL=" . Router::url(null, false);
    echo "<BR>Current URL=" . $this->request->getUri();
    echo "<BR>Current URL=" . $this->request->getUri()->getPath();
    echo "<BR>Current URL=" . $this->request->getRequestTarget();
    echo "<BR>Full URL=" . Router::url("/", true);
    echo "<BR>Base URL=" . Router::url("/", false);
    die("</div>");
}

And output would like this:

Current URL=http://localhost/cake/pages/urls
Current URL=/cake/pages/urls
Current URL=http://localhost/pages/urls?id=20&name=Pritom
Current URL=/pages/urls
Current URL=/pages/urls?id=20&name=Pritom
Full URL=http://localhost/cake/
Base URL=/cake/

How to remove a package from Laravel using composer?

It is important that you must remove all references from your project before execute the command below.

composer remove vendor/package

'C:\Program' is not recognized as an internal or external command

This seems to happen from time to time with programs that are very sensitive to command lines, but one option is to just use the DOS path instead of the Windows path. This means that C:\Program Files\ would resolve to C:\PROGRA~1\ and generally avoid any issues with spacing.

So your command would like below:

C:\PROGRA~1\.......

4. Add the following line to create an alias for dompdf:

'PDF' => Barryvdh\DomPDF\Facade::class

5. Now create a folder named "fonts" in "storage" folder.

This folder will used to store font cache.

6. Now create a Controller as follows:

<?php
namespace App\Http\Controllers;

use PDF;
use Illuminate\Routing\Controller as BaseController;

class HomeController extends BaseController
{
    public function pdf()
    {
        $pdf = PDF::loadView('home.pdf');
        //return $pdf->download('review.pdf'); //Download        
        return $pdf->stream('review.pdf'); //Stream    
    }
}
?>

7. Now create a view under "resource/views/home" named "pdf.blade.php" with following contents:

<!DOCTYPE html>
<html lang="en" >
<head>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/>
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <meta content='width=device-width, initial-scale=1, maximum-scale=1, user-scalable=no' name='viewport'>
</head>
<body>
<h1>Test PDF</h1>
</body>
</html>

Radar Charh with multiple value axis - amCharts

AmChart is now very popular to display data using charts. One of them different charts Radar Chart is most used chart to display graphical data. Its very easy to plot data in radar chart, but we sometimes need multiple radar on same chart. To do so we need to do some extra java-script coding as follows. Below code will also do some extra work such change color of radar as configured.

JavaScript Code:

var chart = AmCharts.makeChart("chartdiv", {
    "type": "radar",
    "theme": "light",
    "addClassNames": true,
    "dataProvider": [{
        "title": "Mango",
        "weight": 100, "count": 1400, "color": "red"
    }, {
        "title": "Banana",
        "weight": 125, "count": 1750, "color": "green"
    }, {
        "title": "Apple",
        "weight": 220, "count": 2850, "color": "blue"
    }, {
        "title": "Blackberry",
        "weight": 200, "count": 2150, "color": "hotpink"
    }, {
        "title": "Gooseberry",
        "weight": 123, "count": 2650, "color": "black"
    }, {
        "title": "Grapes",
        "weight": 98, "count": 1670, "color": "orange"
    }],
    "valueAxes": [{
        "axisTitleOffset": 20,
        "minimum": 0,
        "axisAlpha": 0.15
    }, {
        "id": "v2",
        "axisTitleOffset": 20,
        "minimum": 0,
        "axisAlpha": 0,
        "inside": true
    }],
    "startDuration": 0.2,
    "graphs": [{
        "balloonText": "[[value]] Kg of [[title]] per year",
        "bullet": "round",
        "lineThickness": 2,
        "valueField": "weight"
    }, {
        "balloonText": "[[value]] piece of [[title]] per year",
        "bullet": "square",
        "lineThickness": 2,
        "valueField": "count",
        "valueAxis": "v2"
    }],
    "categoryField": "title",
    "listeners": [{
        "event": "rendered",
        "method": updateLabels
    }, {
        "event": "resized",
        "method": updateLabels
    }],
    "export": {
        "enabled": false
    }
});

function updateLabels(event) {
    try {
        var labels = event.chart.chartDiv.getElementsByClassName("amcharts-axis-title");
        for (var i = 0; i < labels.length; i++) {
            try {
                var color = event.chart.dataProvider[i - event.chart.dataProvider.length + 1].color;
                if (color !== undefined) {
                    labels[i].setAttribute("fill", color);
                }
            } catch (e) {}
        }
    } catch (e) {}

    var x = event.chart.chartDiv.getElementsByClassName("amcharts-graph-line");

    for (var i = 0; i < x.length; i++) {
        try {
            if (i % 2 != 0) {
                var _g = x[i];
                var _p = _g.getElementsByTagName("path");
                _p[0].setAttribute("stroke", "blue");
            }
        }
        catch (e) {}

        var _c = event.chart.chartDiv.getElementsByClassName("amcharts-graph-bullet");
        try {
            for (var c = _c.length / 2; c < _c.length; c++) {
                _c[c].setAttribute("fill", "blue");
            }
        }
        catch (e) {}
    }
}

HtmlCode:

<script src="//www.amcharts.com/lib/3/amcharts.js"></script>
<script src="//www.amcharts.com/lib/3/radar.js"></script>
<script src="//www.amcharts.com/lib/3/themes/light.js"></script>

Git Bash Inside PhpStorm

It would be very helpful if we can use Git Bash inside PhpStorm itself.
The fact is, though, that it's a terminal client and that's how PhpStorm thinks of it. To implement it, you have to go to:

>> File -> Settings -> Tools -> Terminal

Once you're there, here are the steps necessary to enable Git Bash in the Terminal dialogue.
Now you can browse git.sh file from your git installation location.
That would be like below path:
C:\Program Files\Git\bin\sh.exe and it may differ in your machine

And then need to bound the path by double quotation like:
"C:\Program Files\Git\bin\sh.exe"

And add the following line after that "-login -i"

And the final output be like:
"C:\Program Files\Git\bin\sh.exe" -login -i

Your set-up is completed, now press Alt+F12 to see git window inside PhpStorm.

And your are done.
