DataTables around the web

Editor 1.2 available!
Editor 1.2 for DataTables is now available, bringing with it a wide range of improvements, primarily in the PHP implementation for Editor, which now has a much more flexible API and support for Join tables.

Server-side processing and Symfony 2
Slauta Roman has written a server-side processing integration script that works with a Symfony 2 (Doctrine) backend system.

Checkbox selectable plug-in
Basil Gren has developed a Selectable plug-in for DataTables which adds a checkbox column to a table with an API to get and set the selection properties of the table.

Server-side processing PHP PDO style
John Becker of Beckersoft, Inc has updated the default DataTables server-side processing script to make use of PHP's PDO, resulting in a much cleaner implementation.

ThemeForest themes with DataTables
If you are looking for a quick way of creating stylish looking tables, integrated with the rest of your site, then there are a number of themes available on ThemeForest with DataTables support. They are listed here.

Removing index.php from codeigniter URL

Removing index.php from codeigniter URL

Open config.php from system/application/config directory

and replace

$config['index_page'] = “index.php” by $config['index_page'] = “”

 
Create a “.htaccess” file in the root of CodeIgniter directory

and add the following lines.

 
RewriteEngine onRewriteCond $1 !^(index\.php|resources|robots\.txt)
RewriteCond %{REQUEST_FILENAME} !-fRewriteCond %{REQUEST_FILENAME} !-dRewriteRule ^(.*)$ index.php/$1 [L,QSA]

In some case the default setting for uri_protocol does not work properly.

 To solve this problem just replace

$config['uri_protocol'] = “AUTO” by

 $config['uri_protocol'] = “REQUEST_URI” from system/application/config/config.php

PHP : create unique array using array_map

PHP : create unique array using array_map

array(
 array( "Title", 50, 96 ),
 array( "Other Title", 110, 225 ),
 array( "Title", 110, 225 ),
 array( "Title", 110, 225 ),
)

From this array we can show only unique array elements using following function.

$input = array_map("unserialize", array_unique(array_map("serialize", $input)));

Output

array(
 array( "Title" => array( 50, 96 ), array(110, 225) )
 array( "Other Title", array( 110, 225 ) )
)

  "Retrieve": function() {
  document.forms["forgotform"].submit();
  },
  Cancel: function() {
  $( this ).dialog( "close" );
  }
  },
});

How to import json array into jQuery calendar

Hi
I'm trying to feed a jQuery calendar with data from Silverstripe. I've installed the perfectly well-working Calendar Event module, but all I want now is to pull out some Calendar Events and return them as a json array. Here is the code for initiating the calendar:
$(document).ready(function() {

      $('#calendar').fullCalendar({
         draggable: true,
         events: "json_events.php",
         eventDrop: function(event, delta) {
            alert(event.title + ' was moved ' + delta + ' days\n' +
               '(should probably update your database)');
         },
         loading: function(bool) {
            if (bool) $('#loading').show();
            else $('#loading').hide();
         }
      });

   });
And here is the json_events.php:
   $year = date('Y');
   $month = date('m');
   echo json_encode(array(

      array(
         'id' => 1,
         'title' => "Event1",
         'start' => "$year-$month-10",
         'url' => "http://yahoo.com/"
      ),

      array(
         'id' => 2,
         'title' => "Event2",
         'start' => "$year-$month-20",
         'end' => "$year-$month-22",
         'url' => "http://yahoo.com/"
      )

   ));
?>

Window setInterval() Method

Definition and Usage

The setInterval() method will continue calling the function until clearInterval() is called, or the window is closed.
The ID value returned by setInterval() is used as the parameter for the clearInterval() method.
Tip: 1000 ms = 1 second.

Syntax

setInterval(code,millisec,lang)

How to upload image file to remote server with PHP cURL

In this example we learn how to upload static files to remote server using PHP cURL library.

We must know following functionality before we continue this example

Files and Folders

Download Example

For this example we use three files

uploader.php -that receives the files on to the remote server.
handler.php -is used to web based client to upload the file.
curl_handler.php -PHP cURL uploading client to upload file.

Since we use same host to both local and remote server ,we create separate directories

local_files/ - these files will be uploaded to the remote server ,means to uploaded_files directory.
uploaded_files/ – these files are from the uploading client from both web based and PHP cURL based.

uploader.php

 
$upload_directory=dirname(__FILE__).'/uploaded_files/';
//check if form submitted
if (isset($_POST['upload'])) {  
    if (!empty($_FILES['my_file'])) { 
   //check for image submitted
      if ($_FILES['my_file']['error'] > 0) { 
   // check for error re file
            echo "Error: " . $_FILES["my_file"]["error"] ;
        } else {
   //move temp file to our server            
   move_uploaded_file($_FILES['my_file']['tmp_name'], 
   $upload_directory . $_FILES['my_file']['name']); 
   echo 'Uploaded File.';
        }
    } else {
         die('File not uploaded.'); 
   // exit script
    }
}

handler.php

curl_handler.php

$local_directory=dirname(__FILE__).'/local_files/';
 
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_VERBOSE, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible;)");
    curl_setopt($ch, CURLOPT_POST, true);
 curl_setopt($ch, CURLOPT_URL, 'http://localhost/curl_image/uploader.php' );
 //most importent curl assues @filed as file field
    $post_array = array(
        "my_file"=>"@".$local_directory.'shreya.jpg',
        "upload"=>"Upload"
    );
    curl_setopt($ch, CURLOPT_POSTFIELDS, $post_array); 
    $response = curl_exec($ch);
 echo $response;

jQuery Multi select box

Found a jQuery snippet for Multi select box.

HTML :

<select multiple="multiple">
<option value="foo">foo</option>
<option value="bar">bar</option>
<option value="baz">baz</option>
</select>

<div id="target">target</div>

Jquery 1.4

var target = $("#target");

$("select")
  .multiselect()
  .bind("multiselectclick multiselectcheckall multiselectuncheckall", function( event, ui ){

  // the getChecked method returns an array of DOM elements.
  // map over them to create a new array of just the values.
  // you could also do this by maintaining your own array of
  // checked/unchecked values, but this is just as easy.
  var checkedValues = $.map($(this).multiselect("getChecked"), function( input ){
  return input.value;
  });

  // update the target based on how many are checked
  target.html(
  checkedValues.length
  ? checkedValues.join(', ')
  : 'Please select a checkbox'
  );
  })
  .triggerHandler("multiselectclick"); // trigger above logic when page first loads

CSS:

#target { padding: 5px; border: 1px solid #000; width:200px; float:right }

PHP: How to avoid a system generated e-mail going into spam?

Something that gets overlooked often: If you are sending mail manually (i.e. with mail(), not with a framework) and using sendmail, make sure you set the SMTP envelope sender address.

$headers = "MIME-Version: 1.0\r\n"
."Content-Type: text/plain; charset=utf-8\r\n"
."Content-Transfer-Encoding: 8bit\r\n"
."From: =?UTF-8?B?". base64_encode($from_name) ."?= <$from_address>\r\n"
."X-Mailer: PHP/". phpversion();
mail($to, $subject, $body, $headers, "-f $from_address");

-f tells sendmail what address to use in the SMTP wrapper; by default it is the real hostname of the machine, while the from address tends to be an alias. Some spam filters get jumpy when the two addresses don't match.

Other, more obvious advice:

make sure the from/reply to address resolves to the machine you are actually sending from
make sure no spam gets sent from your machine (open relay, other users, a website where you can enter any email address without confirmation)
don't use techniques which are used by spammers to trick filters (e.g. text as image)
