You are free to use it with `{{ }}`.

    {{ Auth::check() ? &#39;yes&#39; : &#39;no&#39; }}

This works:

    {{ Auth::check() ? &#39;yes&#39; : &#39;no&#39; }}

I know this question was asked a while ago, but this may help somebody.

You can now do this in Laravel 5.

    {{ $variable or &quot;default&quot; }}

  [2]: https://laravel.com/docs/5.2/blade#displaying-data

in addition, here is a nice shortcut `?:`, if you you need to print some variable&#39;s value or if it&#39;s empty some default text

    {{ $value ?: &#39;Default Value&#39; }}

For Laravel 5 + php7, you should be using the null coalesce operator as explained in [this Laravel News article][1], like so:

    {{ $value ?? &quot;Fallback&quot; }}

&gt; Before the null coalescing operator, Blade handled the same problem with the “or” operator, which allows a default value when the first value isn’t set, separated by an “or”.

I&#39;m trying to add or edit a variable in my package.json from a shell script. So if i have a package.json like this: 

    {
      &quot;name&quot;: &quot;my-project&quot;,
      &quot;description&quot;: &quot;Project by @DerZyklop&quot;,
      &quot;version&quot;: &quot;0.0.0&quot;,
      ...

I want a&#160;command like

    npm config set foo bar

that adds a new field like 

    {
      &quot;name&quot;: &quot;my-project&quot;,
      &quot;description&quot;: &quot;Project by @DerZyklop&quot;,
      &quot;foo&quot;: &quot;bar&quot;,
      &quot;version&quot;: &quot;0.0.0&quot;,
      ...

...but unfortunately `npm config set` just edits the `~/.npmrc` and not my package.json.

For 2 days now I&#39;m trying to solve this, but unfortunately no result. Let me tell you my story about the problem. I&#39;ve bulid an application on a site, and the application deals with the reviews. But, I&#39;m trying to put it on another site, and I copyed the php files, the sql file from the old site, and moved them to the new site (they are on different FTP servers). When I&#39;m trying to go to the pages from the application, I receive this FATAL ERROR:

&gt; Fatal error: Call to undefined function mysqli_connect()

The code that I wrote to connect to the database is this (with hidden credentials):

    $con = mysqli_connect(&quot;&quot;,&quot;*the_name*&quot;,&quot;*the_pass*&quot;,&quot;*the_database*&quot;);
	if (mysqli_connect_errno()) {
		echo &quot;Failed to connect to MySQL: &quot; . mysqli_connect_error();
	}

Why do I get the error? It works on the old server, and the code I think it&#39;s not the problem, because it works on localhost, and on the new server it doesn&#39;t. Can anyone help me?

Using Laravel 4.2, is it possible to assign a name to a resource controller route?  My route is defined as follows:

    Route::resource(&#39;faq&#39;, &#39;ProductFaqController&#39;);

I tried adding a name option to the route like this:

    Route::resource(&#39;faq&#39;, &#39;ProductFaqController&#39;, array(&quot;as&quot;=&gt;&quot;faq&quot;));

However, when I hit the /faq route and place `{{ Route::currentRouteName() }}` in my view, it  yields `faq.faq.index` instead of just `faq`.

I&#39;m trying to connect with PostgreSQL database through Laravel in order to do a php artisan migrate but doesn&#39;t seem to be directed since it&#39;s reading the database name of MySQL.

Laravel: Error [PDOException]: Could not Find Driver in PostgreSQL

I&#39;m on Ubuntu 14.04 and I&#39;ve been trying all possible methods to install Laravel to no avail. Error messages everything I try. I&#39;m now trying the first method in the quickstart documentation, that is, via Laravel Installer, but it says to &quot;Make sure to place the `~/.composer/vendor/bin` directory in your `PATH` so the Laravel executable is found when you run the Laravel command in your terminal.&quot; so my question is, how do I do that? This may be a simple question but I&#39;m really frustrated and would appreciate any help.

I&#39;m having trouble getting a very-nested relationship to work correctly in laravel.

The wanted behaviour is as follows, 

**I select an event by ID and i want to see which persons are subscribed to it.**
Now the problem is there are some tables between the event and the person..

This is the query that works!

    SELECT persons.id, 
           persons.firstname, 
           persons.lastname, 
           event_scores.score 
    FROM   events 
           JOIN cities 
             ON cities.id = events.city_id 
           JOIN companies 
             ON cities.id = companies.city_id 
           JOIN persons 
             ON companies.id = persons.company_id 
           JOIN event_scores 
             ON event_scores.person_id = persons.id 
    WHERE  event_scores.event_id = 1 
    GROUP  BY persons.id 

# These are my relations #
### Event Model ###

    class Event extends Eloquent
    {
	    protected $table = &#39;events&#39;;

	    public function city()
	    {
		    return $this-&gt;belongsTo(&#39;City&#39;);
	    }
    }
### City Model ###
    class City extends Eloquent
    {
	    protected $table = &#39;cities&#39;;

	    public function companies()
	    {
		    return $this-&gt;hasMany(&#39;Company&#39;);
	    }

	    public function event()
	    {
		    return $this-&gt;hasMany(&#39;Event&#39;);
	    }
    }

### Company Model ###
    class Company extends Eloquent {

	    protected $table = &#39;companies&#39;;

	    public function persons()
	    {
		    return $this-&gt;hasMany(&#39;Person&#39;);
	    }

	    public function city()
	    {
		    return $this-&gt;belongsTo(&#39;City&#39;);
	    }
    }

### Person Model ###
    class Person extends Eloquent
    {
	    protected $table = &#39;persons&#39;;

	    public function company()
	    {
		    return $this-&gt;belongsTo(&#39;Company&#39;);
	    }

	    public function eventscore()
	    {
		    return $this-&gt;belongsToMany(&#39;Event&#39;, &#39;event_scores&#39;, &#39;person_id&#39;, &#39;event_id&#39;)
			    -&gt;withPivot(&#39;score&#39;)
			    -&gt;withTimestamps();
	    }
    }

# What I have tried #

    return Event::with(&#39;city&#39;)-&gt;with(&#39;company&#39;)-&gt;get();

and

	return Event::with(&#39;city&#39;)
		-&gt;whereHas(&#39;companies&#39;, function($query) use ($company_id){
			$query-&gt;where(&#39;company_id&#39;, $company_id);
		})-&gt;get();

And many other possibilities, I&#39;m really stuck on this. Is it so difficult in laravel to achieve this kind of nested relationship linking?

Thanks!

Laravel nested relationships

Laravel has [a `&lt;select&gt;` form helper](http://laravel.com/docs/html#drop-down-lists) which takes as input a dictionary. I like to keep the values for all of these in a central place. For example, I might have an enum that looks like this:

    $phoneTypes = [
        &#39;CELL&#39; =&gt; &quot;Cellular&quot;,
        &#39;HOME&#39; =&gt; &quot;Home&quot;,
        &#39;WORK&#39; =&gt; &quot;Work&quot;,
    ];

Which I want to use in both my view/template, and in the database:

    Schema::create(&#39;customers&#39;, function (Blueprint $table) {
        $table-&gt;increments(&#39;id&#39;);
        $table-&gt;enum(&#39;pri_phone_type&#39;,array_keys($phoneTypes));
        ...
    });

1. Is there a recommended place to put these? 
2. Can I make them global so I can access them easily in all my views?

I want to use an Optional variable with the ternary conditional operator but it is throwing error this error: *optional cannot be used as boolean.* What am I doing wrong?
         
    var str1: String?
    var myBool:Bool
    myBool = str1 ? true : false

How do you use the Optional variable in a ternary conditional operator?

Preparing for the Oracle Certified Associate Java SE 8 Programmer 1 exam, I came across the following paragraph about the ternary expression in the official Study Guide:

&gt;**Ternary Expression Evaluation**
&gt;&lt;br/&gt;
&gt;As of Java 7, only one of the right-hand expressions of the ternary operator will be evaluated at runtime. In a manner similar to the short-circuit operators, if one of the two right-hand expressions in a ternary operator performs a side effect, then it may not be applied at runtime. Let&#39;s illustrate this principle with the following example: [...]

It says that only one of the two expressions is evaluated, demonstrating with the following example:

    int y = 1;
    int z = 1;
    int a = y &lt; 10 ? y++ : z++;

Here, only `y` increments, but `z` does not, as you would expect.

What I am stumbling across is the beginning of the paragraph (marked in yellow) where it says &quot;As of Java 7, ...&quot;. I tested the same code with Java 1.6 and I can&#39;t find a difference in the behavior. I expected Java 1.6 to evaluate both expressions just from the information given in the paragraph. Does anyone have an idea what they wanted to say with &quot;As of Java 7,  ...&quot;?

**Edit:** To avoid confusion: It boils down to the question, Since they write &#39;As of Java 7&#39;, was there anything that changed concerning the ternary operator, when switching from Java 6 to Java 7?

Ternary operator in Java only evaluating one expression since Java 7 - was that different in Java 1.6 and lower?

From what I know, PowerShell doesn&#39;t seem to have a built-in expression for the so-called [ternary operator][1].

For example, in the C language, which supports the ternary operator, I could write something like:

    &lt;condition&gt; ? &lt;condition-is-true&gt; : &lt;condition-is-false&gt;;

If that doesn&#39;t really exist in PowerShell, what would be the best way (i.e. easy to read and to maintain) to accomplish the same result?

Ternary operator in PowerShell

I&#39;m confused as to why this code won&#39;t compile:

    var result = $&quot;{fieldName}{isDescending ? &quot; desc&quot; : string.Empty}&quot;;

If I split it up, it works fine:

    var desc = isDescending ? &quot; desc&quot; : string.Empty;
    var result = $&quot;{fieldName}{desc}&quot;;

How to use the ternary operator inside an interpolated string?

Recently I&#39;m reading the source code of Spring Framework.  Something I can&#39;t understand goes here:

	public Member getMember() {
		// NOTE: no ternary expression to retain JDK &lt;8 compatibility even when using
		// the JDK 8 compiler (potentially selecting java.lang.reflect.Executable
		// as common type, with that new base class not available on older JDKs)
		if (this.method != null) {
			return this.method;
		}
		else {
			return this.constructor;
		}
	}
This method is a member of class `org.springframework.core.MethodParameter`. The code is easy to understand while the comments are hard.

&gt; NOTE: no ternary expression to retain JDK &lt;8 compatibility even when using the JDK 8 compiler (potentially selecting `java.lang.reflect.Executable` as common type, with that new base class not available on older JDKs)

What&#39;s the difference between using ternary expression and using `if...else...` construct in this context?

Displaying the Error Messages in Laravel after being Redirected from controller

I&#39;m rendering a page that is primarily a form with `view::make` in Laravel and it is crashing, causing ERR_CONNECTION_RESET. After a long investigation and many red herrings, I started erasing (not commenting) random sections out of the blade file for the view and realized that if I 

a) erase 2 of the `{{Form}}` calls inside this section of the form 

b) remove the `{{-- and --}}` from around this section of the form

        {{--
        &lt;div class=&quot;form-row&quot;&gt;
          {{ Form::label(&#39;foo&#39;, &#39;foo:&#39;) }}
          {{ Form::text(&#39;foo&#39;) }}
        &lt;/div&gt;
        &lt;div class=&quot;form-row&quot;&gt;
          {{ Form::label(&#39;foo&#39;, &#39;foo:&#39;) }}
          {{ Form::text(&#39;foo&#39;) }}
        &lt;/div&gt;
        &lt;div class=&quot;form-row&quot;&gt;
          {{ Form::label(&#39;foo&#39;, &#39;foo&#39;) }}
          {{ Form::text(&#39;foo&#39;) }}
        &lt;/div&gt;
        --}}

the page will render. I am not sure what exactly the cause here is. There are other blocks above and below, although this is a 3-div commented out section which none of the others are.

Anyone have a clue what is causing this? Running on WAMP if that matters.

Laravel - Blade comments , blade rendering causing page to crash

I have a user-input text displayed on one of the pages. I want to allow new lines, though. How do I display the text, so it is **escaped** AND **allows new lines**?

I used `nl2br()` and Blade&#39;s tripple brackets `{{{$text}}}`, however, obviously, the tripple brackets escape `&lt;br/&gt;` tags as well.

Is there a way to combine escaping and HTML&#39;s new lines using Blade?

Thanks.

Blade: escaping text and allowing new lines

I have this code:

    &lt;select required=&quot;required&quot; class=&quot;form-control&quot; name=&quot;title&quot;&gt;
        &lt;option&gt;&lt;/option&gt;
        @foreach ($titles as $key =&gt; $val)
            @if (stristr($key, &#39;isGroup&#39;))
                &lt;optgroup label=&quot;{{ $val }}&quot;&gt;
            @else
            &lt;option value=&quot;{{ $key }}&quot;&gt;{{ $val }}&lt;/option&gt;
            @endif
        @endforeach
        &lt;/select&gt;

So when the form have errors i use the line `Redirect::route(&#39;xpto&#39;)-&gt;withInput()-&gt;withErrors($v)`. But i can&#39;t re-populate the select fields. Any way to do this without using JavaScript for example?

Define the selected option with the old input in Laravel / Blade

I want to create a select box like the one below using [illuminate\html](https://github.com/illuminate/html/) :

&lt;!-- language: php --&gt;

    &lt;select&gt;
        &lt;option value=&quot;$item-&gt;id&quot;&gt;$item-&gt;name&lt;/option&gt;
        &lt;option value=&quot;$item-&gt;id&quot;&gt;$item-&gt;name&lt;/option&gt;
    &lt;/select&gt;


In my controller I tried this:

&lt;!-- language: php --&gt;

    public function create()
    {
		$items = Items::all([&#39;id&#39;, &#39;name&#39;]);

		return view(&#39;prices.create&#39;, compact(&#39;id&#39;, &#39;items&#39;));
    }

And in my view this:

&lt;!-- language: php --&gt;

    &lt;div class=&quot;form-group&quot;&gt;
	    {!! Form::Label(&#39;item&#39;, &#39;Item:&#39;) !!}
	    {!! Form::select(&#39;item_id&#39;, $items, null, [&#39;class&#39; =&gt; &#39;form-control&#39;]) !!}
	&lt;/div&gt;

The issue is that instead of `$item-&gt;name` is displaying all the info of the entity.
