[`required_without`](http://laravel.com/docs/4.2/validation#rule-required-without) should work.

It means that the field is required if the other field is not present. If have more than two fields and only one is required, use `required_without_all:foo,bar,...`

    $rules = array(
        &#39;Email&#39; =&gt; &#39;required_without:QQ&#39;,
        &#39;QQ&#39; =&gt; &#39;required_without:Email&#39;,
    );

In the example above (given by lucasgeiter) you actually only need one of the conditions not both.

    $rules = array(
        &#39;Email&#39; =&gt; &#39;required_without:QQ&#39;
    );

If you have both rules then filling neither in will result in TWO error messages being displayed. This way it will check that at least one field is filled in and will only display one error message if neither are filled.

Previously I used the following command in bash to find the main ip of my server

    ipaddr=$(/sbin/ifconfig|grep inet|head -1|sed &#39;s/\:/ /&#39;|awk &#39;{print $3}&#39; | grep -v &#39;127.0.0.1&#39;)

But in centos7 it no longer works since ifconfig isn&#39;t available and the command no longer works even if I install `ifconfig` using `yum install net-tools`

What is the equivalent command for centos 7

Thanks a lot

When someone writes &quot;nit: removed whitespace&quot; on a commit, what does &quot;nit&quot; mean? I&#39;ve also seen it capitalized as if it were an abbreviation (i.e. NIT). For an example usage see [this post](https://news.ycombinator.com/item?id=7357149):

&gt; Of course there is a difference between a comment saying: &quot;Nit:
&gt; Trailing whitespace&quot; and &quot;According to Section V, Subsection VII of
&gt; the Coding Manual you should never add trailing whitespace. Please see
&gt; that you don&#39;t.&quot; or some stuff like that. The latter is a
&gt; passive-aggressive potshot, the former IMO is just a quick reminder.

Other example from [&quot;Chromium Code Reviews&quot;](https://codereview.chromium.org/9662):

&gt; Issue 9662: fix minor style nit (Closed)

EDIT: And an answer comes from [Bugzilla&#39;s review page](https://wiki.mozilla.org/Bugzilla:Review):

&gt; Sometimes the reviewer will prefix his comments with &quot;Nit:&quot;. This
&gt; means that he&#39;s just &quot;nitpicking&quot;--you don&#39;t have to fix these points,
&gt; but we&#39;d like you to.

### Introduction ###

I&#39;ve read the following:

&gt; Hypertext Transfer Protocol (HTTP) is the life of the web. It&#39;s used every time you transfer a document, or make an AJAX request. But HTTP is surprisingly a relative unknown among some web developers.
&gt;
&gt; The HTTP verbs comprise a major portion of our “uniform interface” constraint and provide us the action counterpart to the noun-based resource. The primary or most-commonly-used HTTP verbs (or methods, as they are properly called) are POST, GET, **PUT**, and **DELETE**.

### Huh? ###

Well, we came to the point I lost track of things.

`PUT` and `DELETE`, they say. I&#39;ve only ever heard of `POST` and `GET` and never saw something like `$_PUT` or `$_DELETE` passing by in any PHP code I&#39;ve ever viewed.

### My question ###

What are these methods (PUT) and (DELETE) for and if it&#39;s possible to use them in PHP, how would I go about this.

**Note:** I know this is not really a problem but I always grab a learning opportunity if I see one and would very much like to learn to use these methods in PHP if this is possible.

HTTP protocol&#39;s PUT and DELETE and their usage in PHP

## The situation

Let&#39;s say I have a project with two packages installed by Composer:

    php composer.phar require &#39;squizlabs/php_codesniffer:~2.0&#39; &#39;phpmd/phpmd:~2.1&#39;

The autogenerated `composer.json` file looks like this:

    {
        &quot;require&quot;: {
            &quot;squizlabs/php_codesniffer&quot;: &quot;~2.0&quot;,
            &quot;phpmd/phpmd&quot;: &quot;~2.1&quot;
        }
    }

In the autogenerated `composer.lock` file, there are the two requested packages:

* `2.0.0 squizlabs/php_codesniffer`
* `2.1.3 phpmd/phpmd`

and also four dependencies of `phpmd/phpmd`:

* `2.0.4 pdepend/pdepend`
* `2.5.9 symfony/config`
* `2.5.9 symfony/dependency-injection`
* `2.5.9 symfony/filesystem`

A few days later, `squizlabs/php_codesniffer` version `2.1.0` is released, but I don&#39;t want
to run `update` yet. I want to stay on version `2.0.0` for now, and maybe I&#39;ll run `update` in a few days.

---

## The question

I now want to remove `phpmd/phpmd` from my project. I want to achieve the following points:

1. Delete `phpmd/phpmd` from `composer.json`
2. Delete `phpmd/phpmd` from `composer.lock`
3. Delete `phpmd/phpmd` from the `vendor` folder
4. Delete all the dependencies of `phpmd/phpmd` from `composer.lock`
5. Delete all the dependencies of `phpmd/phpmd` from the `vendor` folder
6. Do not update `squizlabs/php_codesniffer` to version `2.1.0`

*Edit:* I&#39;d prefer a solution which doesn&#39;t require changing the
version constraint of `squizlabs/php_codesniffer` in `composer.json`

---

## What I&#39;ve tried

If I run:

    php composer.phar remove phpmd/phpmd

this achieves points **1, 2, 3, 6**, but does not achieve points **4, 5**.

The dependencies of `phpmd/phpmd` remain in `composer.lock` and the `vendor` folder.

If I run:

    php composer.phar remove phpmd/phpmd
    php composer.phar update

this achieves points **1, 2, 3, 4, 5**, but does not achieve point **6**.

`squizlabs/php_codesniffer` gets updated to version `2.1.0`.

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.

I want to send a parameter from controller to layout (i.e. main.php). But I am not able to get the param in main.php

I tried: 

Controller Code: 

    $this-&gt;render(&#39;index&#39;,array(&#39;param&#39; =&gt; $paramValue));

And this is how i was trying to get this in layout ie. main.php

1.  `$this-&gt;param` (as in yii 1)
2.  `$param`

But i am not able to get param value in layout. Can anyone tell me how to do this?

How to pass param from controller to layout in YII2

I&#39;m new to [Facebook Open Graph Protocol][1]. I have been trying to figure out what the meaning of the HTML `prefix` attribute is. The closest post on Stack Overflow I could find dealing with this subject is [this post][2] which was very helpful as it deals with what the differences are among the various possible syntaxes and which one to use.

However the post does not say anything about what this `prefix` attribute is or what it does. AFAIK this is not a standard HTML attribute. I was able to find [this document][3] which I think is where the W3C defines this attribute but was not able to make any sense of it.

Could someone please explain to me:

  1. What does the `prefix` attribute do?

  2. Can I write

    `&lt;html prefix=&quot;og:http://ogp.me/ns#&quot;&gt;`

  instead of

    `&lt;html prefix=&quot;og: http://ogp.me/ns#&quot;&gt;`

  or would that be a syntax error?

  3. Can I include multiple `prefix` attributes for any given HTML tag?

    `&lt;head prefix=&quot;a: http://www.aaa.com/ns#&quot; prefix=&quot;b: http://www.bbb.com/ns#&quot;&gt;`

    Based on my knowledge of HTML, this would be wrong, but then `prefix` is a nonstandard attribute. So perhaps, what I would like to know is, can I write:

    `&lt;head prefix=&quot;a: http://www.aaa.com/ns# b: http://www.bbb.com/ns#&quot;&gt;`

    or does specifying multiple prefixes at any place in the HTML tree not make sense for some reason?

  4. If this `prefix` tag is not part of the HTML spec, how would submitting a page containing this attribute to a code validator ever result in my code being standards compliant?

Thank you for answering my questions.

Meaning of HTML prefix attribute (Open Graph Protocol)?

I have the following controller method:

	@RequestMapping(value=&quot;/map/update&quot;, method=RequestMethod.POST, produces = &quot;application/json; charset=utf-8&quot;)
	@ResponseBody
	public ResponseEntityWrapper updateMapTheme(
			HttpServletRequest request, 
			@RequestBody @Valid List&lt;CompanyTag&gt; categories,
			HttpServletResponse response
			) throws ResourceNotFoundException, AuthorizationException {
    ...
    }

CompanyTag is defined this way:

    public class CompanyTag {
        @StringUUIDValidation String key;
    	String value;
    	String color;
    	String icon;
    	Icon iconObj;
    	
    	public String getKey() {
    		return key;
    	}
    	
    	public void setKey(String key) {
    		this.key = key;
    	}
       ...
    }

The problem is that validation is not triggered, the CompanyTag list is not validated, the &quot;StringUUIDValidation&quot; validator is never called.  

If I remove the List and only try to send a single CompanyTag, i.e. instead of:

	@RequestBody @Valid List&lt;CompanyTag&gt; categories,
use:

	@RequestBody @Valid CompanyTag category,

 it works as expected, so apparently Spring does not like to validate lists of things (tried with array instead, that did not work either). 

Anybody have any idea what&#39;s missing?

Validation of a list of objects in Spring

I need to validate the date from the user and check if it is in a particular format. If yes, then it will be accepted else it will not be. I am looking for sort of 
    
    value.match(&quot;regular expression&quot;) 

The above works fine if, I  have to choose from few formats. So, I came across this moment.js and interested in knowing how to use isSame(). I tried implementing it but unsuccessful.  Like :

    var x=moment(&quot;MM/DD/YYYY&quot;) ;
    x.isSame(&quot;28-02-1999&quot;);  // am getting false which is right
    var x=moment(&quot;28-02-1999&quot;,&quot;DD-MM-YYYY&quot;) ;
    x.isSame(&quot;28-02-1999&quot;);  // am getting false which is wrong

So, please help in that.
Thanks

I&#39;m initiating in Laravel. 
I searched and not found how to validate data with some ENUM values. On below code I need that `type` must be just `DEFAULT` or `SOCIAL`. One or other:

    $validator = Validator::make(Input::only([&#39;username&#39;, &#39;password&#39;, &#39;type&#39;]), [
        &#39;type&#39; =&gt; &#39;&#39;, // DEFAULT or SOCIAL values
        &#39;username&#39; =&gt; &#39;required|min:6|max:255&#39;,
        &#39;password&#39; =&gt; &#39;required|min:6|max:255&#39;
    ]);

Is possible?

Laravel IN Validation or Validation by ENUM Values

I searched and can&#39;t figure out how to [validate the new reCaptcha][1],  before form submit, along with the validate function of [jQuery validation Plugin][2].

My intent:

        $.validator.addMethod(&#39;reCaptchaMethod&#39;, function (value, element, param) {
				if (grecaptcha.getResponse() == &#39;&#39;){
					return false;
				} else {
                    // I would like also to check server side if the recaptcha response is good
					return true
				}
			}, &#39;You must complete the antispam verification&#39;);


		$(&quot;#form&quot;).validate({
				rules: {
					name: {
						required: true,
						minlength: 2
					},
					email: {
						required: true,
						email: true
					},
					reCaptcha: {
						reCaptchaMethod: true	
					}
				},
				messages: {
					name: &quot;Please fill your name&quot;,
					email: &quot;Please use a valid email address&quot;
				},
				submitHandler : function () {
							$.ajax({
								type : &quot;POST&quot;,
								url : &quot;sendmail.php&quot;,
								data : $(&#39;#form&#39;).serialize(),
								success : function (data) {
									$(&#39;#message&#39;).html(data);
								}
							});
						}
						
		
			});

In a few words: I would like to check server-side, with the [remote method][3], if the user has passed the recaptcha validation BEFORE submitting the form, along with other rules of validation.

I&#39;m able to check the recaptcha *AFTER* submission (on sendmail.php), but it would be nicer to have the recaptcha validation response along with other fields validation.

The main reason is for a better user experience, having all fields checked at once.

I&#39;ve managed to achieve this, moving the check inside the submitHandler:

				submitHandler : function () {
					  if (grecaptcha.getResponse() == &#39;&#39;){
						  // if error I post a message in a div
						  $( &#39;#reCaptchaError&#39; ).html( &#39;&lt;p&gt;Please verify youare human&lt;/p&gt;&#39; );
						  
					  } else {
					 
							$.ajax({
								type : &quot;POST&quot;,
								url : &quot;sendmail.php&quot;,
								data : $(&#39;#form&#39;).serialize(),
								success : function (data) {
									$(&#39;#message&#39;).html(data);
								}
							});
						}
						
				 }

But I don&#39;t like this approach, for 2 reasons:

 1. It is just checking if the recaptcha has been filled, not if it&#39;s valid, and
 2. User feels like it is a 2 step verification.

[In this answer][4] they say it can be done rendering the Recaptcha on a callback, to specify a function call on a successful CAPTCHA response.

I tried to implement that, but I&#39;ve not been able to use this solution within a rule of the validate() function.

       the manual that corresponds to your MariaDB server version for the right syntax to use near &#39;&#39;users&#39; MODIFY &#39;age&#39; DATETIME&#39; at line 1

Run raw SQL in migration

Currently, I am using 

&gt; Carbon::now()

It Displays date with the time

&gt; 2015-03-10 23:23:46

But I only need a date

**2015-03-10**
