If I recall correctly Twig doesn&#39;t support `||` and `&amp;&amp;` operators, but requires `or` and `and` to be used respectively. I&#39;d also use parentheses to denote the two statements more clearly although this isn&#39;t technically a requirement.

    {%if ( fields | length &gt; 0 ) or ( trans_fields | length &gt; 0 ) %}

Expressions

    Expressions can be used in {% blocks %} and ${ expressions }.

    Operator	Description
    ==	        Does the left expression equal the right expression?
    +	        Convert both arguments into a number and add them.
    -	        Convert both arguments into a number and substract them.
    *	        Convert both arguments into a number and multiply them.
    /	        Convert both arguments into a number and divide them.
    %	        Convert both arguments into a number and calculate the rest of the integer division.
    ~	        Convert both arguments into a string and concatenate them.
    or	        True if the left or the right expression is true.
    and	        True if the left and the right expression is true.
    not	        Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:
    
    {% if (foo and bar) or (fizz and (foo + bar == 3)) %}

Using `!=` for multiple conditions does not work for me either, however `==` does work - indeed this seems like a bug.

Possible work around.
```
{% if key not in [&#39;string1&#39;, &#39;string2&#39;] %}
// print something
{% endif %}
```

I have a certain element that I can select with [Selenium][1] 1.

Unfortunately I need to click the parent element to get the desired behaviour. The element I can easily locate has attribute unselectable, making it dead for clicking. How do I navigate upwards with [XPath][2]?

I&#39;d like to add new line with text to my date.txt file, but instead of adding it into existing date.txt, app is creating new date.txt file..
   

    TextWriter tw = new StreamWriter(&quot;date.txt&quot;);

    // write a line of text to the file
    tw.WriteLine(DateTime.Now);

    // close the stream
    tw.Close();

I&#39;d like to open txt file, add some text, close it, and later after clicking something: open date.txt, add text, and close it again.

So i can get: 

Button pressed: txt opened -&gt; added current time, then close it. Another button pressed, txt opened -&gt; added text &quot;OK&quot;, or &quot;NOT OK&quot; in the same line, then close it again.

So my txt file will look like that:

    2011-11-24 10:00:00 OK
    2011-11-25 11:00:00 NOT OK

How can i do this? Thanks!

How to add new line into txt file

It seem I have problem with a twig if statement.

    {%if fields | length &gt; 0 || trans_fields | length &gt; 0 -%}

The error is:

    Unexpected token &quot;punctuation&quot; of value &quot;|&quot; (&quot;name&quot; expected) in 

I can&#39;t understand why this doesn&#39;t work, it&#39;s like if twig was lost with all the pipes.

I&#39;ve tried this :

    {% set count1 = fields | length %}
    {% set count2 = trans_fields | length %}
    {%if count1 &gt; 0 || count2 &gt; 0 -%}

but the if also fail.

Then tried this:

    {% set count1 = fields | length &gt; 0 %}
    {% set count2 = trans_fields | length &gt; 0 %}
    {%if count1 || count2 -%}

And it still doesn&#39;t work, same error every time ...


So... that lead me to a really simple question: does Twig support multiple conditions IF ?

twig: IF with multiple conditions

It seem I have problem with a twig if statement.

The error is:
<pre><code class="hljs language-arduino">Unexpected token "punctuation" of value "|" ("name" expected) in 
</code></pre>
I can't understand why this doesn't work, it's like if twig was lost with all the pipes.
I've tried this :
<pre><code class="hljs language-ini">{% set count1 = fields | length %}
{% set count2 = trans_fields | length %}
{%if count1 > 0 || count2 > 0 -%}
</code></pre>
but the if also fail.
Then tried this:

And it still doesn't work, same error every time ...

Is there anything out there like Github that is for your own local server?  I am curious if there is like a PHP script or even a desktop client that mimics Github&#39;s functionality, I love Github but it would be nice to host on my own server.

Apologies if this isn&#39;t considered &quot;programming&quot; enough but generally only programmers use GIT and Github


----------
## Update ##

First of all thanks for all the great suggestions, it is great to see there are options out there.  From what is posted here and from my googling I can say it looks like the best looking/most alike to Github solutions are coded in Ruby, which is great for some but I am a PHP kind of guy (for now).

Most of the PHP GIT viewers either are  outdated and abandoned projects or they just look like crap ( I realize I could fix them up to be more like Github) but I ran across something in PHP that looks promising so far.  It is called Glip it is on Github here https://github.com/patrikf/glip and to me it is the most attractive and easy to use solution I have found for PHP so far.  For the advanced Git user, it may not be enough but for me, I just wanted to be able to view a git repo and that provides that functionality.

Now my search still continues for the perfect solution, will I ever find it?  I hope so but, for now, this is we got.  I am considering writing my own, one that is attractive like Github and has other features like an Issue tracker for bug and feature requests.  All the ones I have seen so far are not so good

How can I have Github on my own server?

The PHP manual states 

&gt; It is not possible to use `$this` from anonymous function before PHP
&gt; 5.4.0

on the [anonymous functions page][1].  But I have found I can make it work by assigning `$this` to a variable and passing the variable to a `use` statement at the function definition.

	$CI = $this;
	$callback = function () use ($CI) {
		$CI-&gt;public_method();
	};

Is this a good practice?  
Is there a better way to access `$this` inside an anonymous function using PHP 5.3?

I have read and read articles on PHPUnit, SimpleTest, and other Unit Testing frameworks. They all sound so great! I finally got PHPUnit working with Codeigniter thanks to https://bitbucket.org/kenjis/my-ciunit/overview

Now my question is, how do I use it?

Every tutorial I see has some abstract use like `assertEquals(2, 1+1)` or:

    public function testSpeakWithParams()
    {
        $hello = new SayHello(&#39;Marco&#39;);
        $this-&gt;assertEquals(&quot;Hello Marco!&quot;, $hello-&gt;speak());
    }

That is great if I had a function that would output such a predictable string. Usually my apps grab a bunch of data from the database then display it in some sort of table. So how do I test Codeigniter&#39;s controllers? 

I would like to do Test-Driven Development and I have read the tutorial on PHPUnits site, but once again the example seem so abstract. Most of my codeigniter functions are displaying data.

Is there a book or a great tutorial with a practical application and examples of PHPUnit testing?

I&#39;ve searched a lot on the net how to access the global `$_SESSION` array from TWIG template and found this: `{{app.session.get(&#39;index&#39;)}}`, but when I&#39;m calling it, it returns an empty string. I have a `$_SESSION[&#39;filter&#39;][&#39;accounts&#39;]` and I&#39;m getting this error when calling `{{app.session.get(&#39;filter&#39;).accounts}}`: `Item &quot;accounts&quot; for &quot;&quot; does not exist`. What I&#39;m doing wrong?

Accessing session from TWIG template

Basically I use this handy function to processing db rows (close an eye on PDO and/or other stuff)

    function fetch($query,$func) {
        $query = mysql_query($query);	
    	while($r = mysql_fetch_assoc($query)) {
    		$func($r);
    	}
    }

With this function I can simply do:

    fetch(&quot;SELECT title FROM tbl&quot;, function($r){
       //&gt; $r[&#39;title&#39;] contains the title
    });

Let&#39;s say now I need to concatenate all `$r[&#39;title&#39;]` in a var (this is just an example).

How could I do that? I was thinking something like this, but it&#39;s not very elegant:
    
    $result = &#39;&#39;;
    fetch(&quot;SELECT title FROM tbl&quot;, function($r){
       global $result;
       $result .= $r[&#39;title&#39;];
    });
    
    echo $result;

I have Symfony 2.0.9 standard edition installed with JMSSecurityBundle.  Just wondering what functions are available to me in a Twig template to deal with users?

Specifically I want check to see if a user has the role ROLE_ADMIN.

Any help?

Thanks

In Twig template I check if a field has an error like this:

    {% if form.points.get(&#39;errors&#39;) is not empty %}

Is there any method like:

    {% if form.points.hasErrors() %}

to do it simpler? It&#39;s not a big difference, but if I can&#39;t do it easier why not.

I want to implement ternary conditional operator in MySQL. I have a table in which one field id exist. Its value may be null. I want to display `id` in ternary conditional format like this:

    select id = id == null ? 0 : id;

Is it possible in MySQL?


How to implement ternary conditional operator in MySQL

Why does the first return a reference?

	int x = 1;
	int y = 2;
	(x &gt; y ? x : y) = 100;

While the second does not?

	int x = 1;
	long y = 2;
	(x &gt; y ? x : y) = 100;

Actually, the second did not compile at all - &quot;not lvalue left of assignment&quot;.


Return type of &#39;?:&#39; (ternary conditional operator)

I know that in PHP 5.3 instead of using this redundant ternary operator syntax:

    startingNum = startingNum ? startingNum : 1

...we can use a shorthand syntax for our ternary operators where applicable:

    startingNum = startingNum ?: 1

And I know about the ternary operator in JavaScript:

    startingNum = startingNum ? startingNum : 1

...but is there a shorthand?




JavaScript shorthand ternary operator

Can we use `elif` in list comprehension?  

Example :  

    l = [1, 2, 3, 4, 5]

    for values in l:
        if values==1:
            print &#39;yes&#39;
        elif values==2:
            print &#39;no&#39;
        else:
            print &#39;idle&#39;

Can we include the `elif` in our list comprehension, in a similar fashion to the code above?

For example, an answer like:   

    [&#39;yes&#39;, &#39;no&#39;, &#39;idle&#39;, &#39;idle&#39;, &#39;idle&#39;]

Up until now, I have only used `if` and `else` in list comprehension.

`elif` in list comprehension conditionals

How can I use an inline `if` statement in JavaScript? Is there an inline `else` statement too?

Something like this:

    var a = 2;
    var b = 3;
    
    if(a &lt; b) {
        // do something
    }
