Get document root path using yii application

dirname(Yii::app()->request->scriptFile)

CGridView a CLinkColumn with sortable header using yii

I have it working with the latest yii (non-stable but might work with the current stable release). (could do with some improvement but it does what I need)

Try this; create a new component under components/SCLinkColumnWithSort.php

<?php
class SCLinkColumnWithSort extends CLinkColumn
{

  public $name;
  public $sortable = true;
  public $filter;

  protected function renderFilterCellContent()
  {
    $this->linkHtmlOptions['class'] = $this->name;
    if($this->filter!==false && $this->grid->filter!==null && strpos($this->name,'.')===false)
    {
      if(is_array($this->filter))
        echo CHtml::activeDropDownList($this->grid->filter, $this->name, $this->filter, array('id'=>false,'prompt'=>''));
      else if($this->filter===null)
        echo CHtml::activeTextField($this->grid->filter, $this->name, array('id'=>false));
      else
        echo $this->filter;
    }
    else
      parent::renderFilterCellContent();
  }

  protected function renderHeaderCellContent()
  {
    if($this->grid->enableSorting && $this->sortable && $this->name!==null)
      echo $this->grid->dataProvider->getSort()->link($this->name,$this->header);
    else
      parent::renderHeaderCellContent();
  }

}
?>

Use this as following:

<?php
$this->widget('zii.widgets.grid.CGridView', array(
  'dataProvider' => $dataProvider,
  'columns' => array(
    array(
      'class' => 'SCLinkColumnWithSort',
      'name' => 'column_name_to_sort',
     )
  )
))
?>

Or you can directly use, but upper one used for more customization:

array(
  'name' => 'mobile_number',
  'type' => 'raw',
  'value' => 'CHtml::link($data->mobile_number,$data->contact_id)'
)

Where mobile_number is filed value in name, in value, mobile_number is for sorting

and contact_id is for making link.

Create and download csv file from array using php

Create and download csv file from array using php.

<?php
function arrayToCsv( array $fields, $delimiter = ';', $enclosure = '"', $encloseAll = false, $nullToMysqlNull = false ) {
    $delimiter_esc = preg_quote($delimiter, '/');
    $enclosure_esc = preg_quote($enclosure, '/');

    $outputString = "";
    foreach($fields as $tempFields) {
        $output = array();
        foreach ( $tempFields as $field ) {
            if ($field === null && $nullToMysqlNull) {
                $output[] = "NULL";
                continue;
            }

            // Enclose fields containing $delimiter, $enclosure or whitespace
            if ( $encloseAll || preg_match( "/(?:${delimiter_esc}|${enclosure_esc}|\s)/", $field ) ) {
                $output[] = $enclosure . str_replace($enclosure, $enclosure . $enclosure, $field) . $enclosure;
            }
            else {
                $output[] = $field;
            }
        }
        $outputString .= implode( $delimiter, $output )."\n";
    }
    return $outputString;
}
?>

Use:

<?php
$dataArray = array();
array_push($dataArray, array(
    "First Name",
    "Last Name",
    "Number",
    "Group"
));
foreach($dataList as $index => $data) {
    array_push($dataArray, array(
        "".$data["first_name"],
        "".$data["last_name"],
        "".$data["mobile_number"],
        "".$data["group_name"]
    ));
}
$csvString = arrayToCsv($dataArray);
header("Content-type: text/csv");
header("Content-Disposition: attachment; filename=list.csv");
header("Pragma: no-cache");
header("Expires: 0");
echo $csvString;
?>

Php check a value exists in multi level array and return path

Search in array using php by value if the array is any depth data.

<?php
function array_value_exists($search = "", $searchArray = array(), $returnKey = false, &$returnKeyArray = array(), $level = 0) {
    $returnValue = false;
    $search = trim(strval($search));
    if(strlen($search) == 0) {
        return false;
    }
    if(is_null($searchArray)) {
        return false;
    }
    if(!is_array($searchArray)) {
        return false;
    }
    foreach($searchArray as $key => $value) {
        array_push($returnKeyArray, $key);
        if(is_string($value)) {
            if($search == trim($value)) {
                $returnValue = true;
                break;
            }
        } else if(is_array($value)) {
            $returnValue = array_value_exists($search, $value, false, $returnKeyArray);
            if($returnValue == true) {
                break;
            }
        }
    }
    if($returnKey == true) {
        return $returnKeyArray;
    }
    return $returnValue;
}
?>

Use:<?php
$ary = array(
            "bm" => array(
                "dev" => array(
                    "pritom" => array(
                        "email" => "pritomkucse@yahoo.com"
                    ),
                    "touhid" => array(
                        "email" => "touhid@yahoo.com"
                    )
                ),
                "designer" => array(
                    "dipu" => array(
                        "email" => "dipu@yahoo.com"
                    )
                )
            ),
            "gpit" => array(
                "dev" => array(
                    "sanat" => array(
                        "email" => "sanat@gpit.com"
                    )
                )
            )
        );
        $has = array_value_exists("pritomkucse@yahoo.com", $ary);
        echo $has == true ? "True" : "False";
        print_r(array_value_exists("pritomkucse@yahoo.com", $ary, true));
?>

Output:
1. True (Find or not)
2. Path to this value.

Array
(
    [0] => bm
    [1] => dev
    [2] => pritom
    [3] => email
)

Android custom dialog example

In this tutorial, we show you how to create a custom dialog in Android. See following steps :

Create a custom dialog layout (XML file).
Attach the layout to Dialog.
Display the Dialog.
Done.

1 Android Layout Files

Two XML files, one for main screen, one for custom dialog.
File : res/layout/main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:orientation="vertical" >
 
    <Button
        android:id="@+id/btnLogin"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="Login Dialog" />
 
</LinearLayout>

File : res/layout/login.xml

            android:layout_height="wrap_content"
            android:text="@string/sldjfsjdflsdf"
            android:textAppearance="?android:attr/textAppearanceLarge" />

        <LinearLayout

                android:layout_height="45dp"
                android:src="@drawable/user" />

            <EditText
                android:id="@+id/editText1"

                <requestFocus />
            </EditText>

        </LinearLayout>

        <LinearLayout
            android:id="@+id/linearLayout2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content" >

            <ImageView
                android:id="@+id/imageView2"
                android:layout_width="45dp"
                android:layout_height="45dp"
                android:src="@drawable/password" />

            <EditText
                android:id="@+id/editText2"
                android:layout_width="wrap_content"

                android:layout_weight="1"
                android:inputType="textPassword" />

        </LinearLayout>

        <Button
            android:id="@+id/btnLoginPrompt"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:text="@string/login" />

    </TableLayout>

Read the comment and demo in next step, it should be self-explorary.

Button btnLogin = (Button)findViewById(R.id.btnLogin);
btnLogin.setOnClickListener(new OnClickListener() {   
 public void onClick(View arg0) {
  final Dialog dialog = new Dialog(ContactspaceandroidActivity.this);
  dialog.setContentView(R.layout.login);
  dialog.setTitle("Title...");
  
  dialog.show();
  
  Button azxc = (Button) dialog.findViewById(R.id.btnLoginPrompt);
  azxc.setOnClickListener(new OnClickListener() {    
   @Override
      public void onClick(View arg0) {
       System.out.println("BTN LOGIN CLICKED.");
       EditText txtUserName = (EditText) dialog.findViewById(R.id.txtUserName);
       EditText txtPassword = (EditText) dialog.findViewById(R.id.txtPassword);
       if(txtUserName.getText().length() <= 0) {
        Toast.makeText(ContactspaceandroidActivity.this, "Enter username.", Toast.LENGTH_LONG).show();
        return;
       }
       if(txtPassword.getText().length() <= 0) {
        Toast.makeText(ContactspaceandroidActivity.this, "Enter password.", Toast.LENGTH_LONG).show();
        return;
       }
      }
  });    
 }
});

Php making a soap based server with basic authentication

Compared to the standard authentication in the rest of your applications, SOAP authentication isn't too complicated. There are two easy ways of integrating it into your SOAP server: using HTTP Basic authentication or processing a custom SOAP header.

Soap-server:

<?php
function pc_authenticate_user($username, $password)
{
    $is_valid = false;
    if(strlen(trim($username)) > 0 && trim($username) == "adm" && strlen(trim($password)) > 0 && trim($password) == "pwd") {
        $is_valid = true;
    }
    if ($is_valid) {
        return true;
    }
    else {
        return false;
    }
}
class pc_SOAP_return_time
{
    public function __construct() {
        // Throw SOAP fault for invalid username and password combo
        if (!pc_authenticate_user($_SERVER['PHP_AUTH_USER'], $_SERVER['PHP_AUTH_PW']) ) {
            throw new SOAPFault("Incorrect username and password combination.", 401);
        }
    }

    function return_time($name, $lastName) {
        return "Time: ".time().", First Name: ".$name.", Last Name: ".$lastName;
    }

    function accept_xml() {
        $postData = file_get_contents("php://input");
        return $postData;
    }
}
$server = new SOAPServer(null, array('uri' => 'urn:pc_SOAP_return_time'));
$server->setClass('pc_SOAP_return_time');
$server->handle();

Soap-client

<?php
$opts = array(
    'location' => 'http://localhost/ci/dragon71/soap-check/server.php',
    'uri' => 'urn:pc_SOAP_return_time',
    'login' => 'adm',
    'password' => 'pwd'
);

$client = new SOAPClient(null, $opts);

$result = $client->__soapCall('return_time', array("Pritom", "Kumar"));
print_r($result);

Or

<?php
$xml = '<?xml version="1.0" encoding="utf-8"?>'.
    '<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"'.
    ' xmlns:xsd="http://www.w3.org/2001/XMLSchema"'.
    ' xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">'.
    '<soap:Body>'.
    '<accept_xml xmlns="http://localhost/ci/dragon71/soap-check/server.php/">'.
    '<ItemId>15</ItemId>'.
    '</accept_xml>'.
    '</soap:Body>'.
    '</soap:Envelope>';

$url = "http://localhost/ci/dragon71/soap-check/server.php";

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);

$headers = array();
array_push($headers, "Content-Type: text/xml; charset=utf-8");
array_push($headers, "Accept: text/xml");
array_push($headers, "Cache-Control: no-cache");
array_push($headers, "Pragma: no-cache");
if($xml != null) {
    curl_setopt($ch, CURLOPT_POSTFIELDS, "$xml");
    array_push($headers, "Content-Length: " . strlen($xml));
}
curl_setopt($ch, CURLOPT_USERPWD, "adm:pwd"); /* If required */
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
$response = curl_exec($ch);
$code = curl_getinfo($ch, CURLINFO_HTTP_CODE);
header('Content-Type: text/xml');
print_r($response);

Make sure you have soap enabled in your server machine. Write "phpinfo();" and look for the word "Soap Client" as below:

If you don't find above soap enabled then you have to enable it. Navigate explorer to /c/xampp/php and edit "php.ini" and uncomment the line marked in below image and restart server and check again if your server has soap enabled:

If you want to execute soap using curl follow this link
