jquery UI tab – ajax loading CKEDITOR in a tab and some issues

Tags

ajax, ckeditor, Jquery UI, PHP

I tried to load CKEDITOR in a jquery tab via ajax. I got problem that only first time the ckeditor is working but when I click on other tab and again got o ckeditor tab its not working. in Load section for tab I put the following code.

load: function(event, ui) {
  if(ui.index == 3){ // Checked tab no 4
    var instance = CKEDITOR.instances['reditor']; // reditor is text area id, check if instances exists for readitor or not 
    if(instance){ 
       CKEDITOR.remove(instance); //if existed then remove it
    }
    CKEDITOR.replace( 'reditor' ); // Create instance for 'reditor'
 }
}

in this way we can get rid the problem of “CKEditor instance already exists”

Here is whole configuration

$(document).ready(function () {
           var $tabs = $("#tabs").tabs({ 
                                
                                alignment: "top",
                                spinner : false,
                                ajaxOptions: {
                                    error: function( xhr, status, index, anchor ) {
                                                    $( anchor.hash ).html( "Couldn't load this tab. Please try again.");
                                                },
                                    complete: function(){
                                        
                                        
                                    }
                                    
                                },
                                load: function(event, ui) {
                                    if(ui.index == 3){
                                        var instance = CKEDITOR.instances['reditor'];
                                        if(instance){
                                            CKEDITOR.remove(instance);
                                        }
                                    }
                                },
                                select: function(e, ui){
                                            $(ui.panel).html('<img src="img/ajax_loader.gif" />'); // Loader after click on each tab
                                        }
                                
                                });
           $tabs.tabs('select', <?=$tab_no?>); // used for selected default tab
           
        });
        

Here is HTML/PHP (I used cakephp syntax for url ) used “TEXT” in a link to show the loading text on tab otherwise it will not show the loading tabl

<div id="tabs">
    <ul>
        <li>
            <?=$html->link("<span>Information</span>", array("controller" => "listings", "action" => "information", $id), array("escape" => false, "title" => "Information"))?>
            
        </li>
        <li>
            <?=$html->link("<span>Detail</span>", array("controller" => "listings", "action" => "detail", $id), array("escape" => false))?>
        </li>
        <li>
            <?=$html->link("<span>Peoples</span>", array("controller" => "listing", "action" => "peoples", $id), array("escape" => false))?>
        </li>
        <li>
            <?=$html->link("<span>Enhance</span>", array("controller" => "listings", "action" => "enhance", $id), array("escape" => false))?>
       </li>
    </ul>
 </div>

In this way I did and it work for me 🙂

trace visitor location based on their geolocation- how to

block ip, find country, geo location, PHP

I tried to find out a solution how we can block or trace visitor location and based on that location we do some action

First you have to use 3rd party api to get visitor location. The following url will give you the detail.
http://ipinfodb.com/ip_location_api.php

Lets assume the visitor ip is 180.234.12.237 (you’ll get key from that website)
http://api.ipinfodb.com/v3/ip-city/?key=&ip=180.234.12.237

Its has some response format that is xml, json, raw, just you have to pass a get variable &format=json

  if (getenv(HTTP_X_FORWARDED_FOR)){
        $pipaddress = getenv(HTTP_X_FORWARDED_FOR);
        $ipaddress = getenv(REMOTE_ADDR);
        //echo "Your Proxy IPaddress is : ".$pipaddress. "(via $ipaddress)" ;
    } else {
        $ipaddress = getenv(REMOTE_ADDR);
        //echo "Your IP address is : $ipaddress";
    }     

    

$_API = "83838s88s4e0a65jhk80246d77d8s5s3988d9fb1asdkf000asd8fslasdlfasdf6s9sce";
$_URL = "http://api.ipinfodb.com/v3/ip-country/?key=$_API&ip=$ipaddress&format=json";

$data = file_get_contents($_URL);

$data = json_decode($data);
if(isset($data->statusCode) && $data->statusCode == "OK"){
    if(isset($data->countryCode) && ($data->countryCode != "USA" )) || $data->countryCode != "BD")){
        header("Location:http://www.yourdomain.com/geolocation.php");     
        exit;
    }
}

In this way we can find out the country, city, post code, time zone etc. we can block or trace visitors in our website.

Extract Zip File Using PHP

PHP, unzip, zip, ziparchive

Sometime we need to extract a file on the server, say you don’t have access to shell and you want to extract a zip file, just put this to a php file and upload and run

     $zipObj = new ZipArchive;
     $file = $zipObj->open(’zip_file_name.zip’);
     if ($file == TRUE) {
         $zipObj->extractTo('extract_directory/');
         $zipObj->close();
         echo 'Unzip Successfully';
     } else {
         echo 'Failed to unzip';
     }

Its very simple and available idea everywhere, i jut wrote for note
Done!!! 🙂

I know this one is old thing and helps is available but sometime we need to fetch twitter feeds Retwittet, Mentions, to our websites. Now i used json request and format the texts and print.

 function twi_fid(){
  
  ## NUMBER OF TWITTET 
  $size = 5;
  
  ## FETCH THE TWITTER TWITTET
  $twittet = file_get_contents("http://api.twitter.com/1/statuses/user_timeline.json?screen_name=bdsarwar&count=$size&include_rts=t&include_entities=t");
  
  
  $data = json_decode($twittet);
  $o_text = "";
  foreach($data as $t)
  {
      $o_text = $t->text;
      
      ## MAKING URLS ENABLE TO TEXT
      $entities = $t->entities;
      
      $i = 0;
      foreach($entities->urls as $url)
      {
          $indicate = $url->indices;

          $replace[$i] = $url->url;
          $string[$i] = "<a target='_blank' href='".$url->url."'>".$url->url."</a>";

          
          $i++;
      }
      
      ## MAKING MENTIONS 
      foreach($entities->user_mentions as $mention)
      {
          $indicate = $mention->indices;
          
          $string[$i] = "<a target='_blank' href='http://www.twitter.com/".$mention->screen_name."'>".$mention->screen_name."</a>";
          $replace[$i] = $mention->screen_name;
          
          $i++;
      }
     
      for($i = 0; $i < count($string); $i++)
      {
          
          $pattarn = $replace[$i];
          $o_text = str_replace($pattarn, $string[$i], $o_text);
     
      }
      
    echo $o_text;
    echo "<br />";
    echo date("d/m/Y, H:m a", strtotime($t->created_at));
    echo "<br/> ___ <br />";

      
  }

use PHP print_r function and return a string

Tags

debug, PHP, print_r, var_dump

print_r is one of the most useful feature of PHP, print_r prints a human-readable string representation of a variable. Sometime we need to get print_r value as sting to log or to combine the messages.

You can notice that print_r function have two argument first one is for string/array to be printed and another one use for whether it will print or return as string

#To have print_r return the data as a string, include the second argument "true":
$message = print_r($obj, true);

sometime you might be need to use var_export function instead of print_r

$msg = var_export($obj, true);

I use this several time while I debugging.

Happy Debugging 🙂

storing array to mysql and retrieve string and use it as variable using php

Tags

array, PHP, serialize, store, unserialize

Sometime we need to store array to database then we need to retrieve and use as variable array. I used session variable to save data and used it later.

Its simple just use the following

#using serialize() method
$data = serialize($_SESSION);
$sql = "Insert into sessioninfo `data` values('$data')";

just run the above query and save the whole session data into a database table. You might be use any array here.

Now retrieve the data

# I assume you can retrieve the data from database and assign to the following variable
$data = unserialize($row['data']);

Now $data have the same value or nested array.

So just using serialize() and unserialize() we can do this.

Done !

direct to specific page instead of get variable www.domain.com/username using php and .htaccess

Tags

.htaccess, PHP, url rewrite

Sometime we need to get direct access any specific page. We need a user profile page http://www.domain.com/username, but our actual url is http://www.domain.com/profile/profile.php?username=Abc

I’m trying to describe how to make the url friendly, I used .htaccess and php for rewrite the url.
.htaccess

    RewriteEngine On
    RewriteCond %{REQUEST_FILENAME} !-d
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^(.*)$ index.php?uri=$1 [QSA,L]

In this case the uri took parameter after index.php file.
So if url is http://www.domain.com/username
uri will have the value uri=useranme

We need following code to retrieve the parameter.

 $_SERVER['QUERY_STRING']

I followed the following way inside index.php file to get the username

  $flag = false; 
  if(isset($_SERVER['QUERY_STRING']))
  {
      $q = $_SERVER['QUERY_STRING'];
      $data = explode("=",$q);  // Assume uri=username 
      if(isset($data[0]) && isset($data[1]) && $data[0] == 'uri')
      {
          $a = $data[1];
          $q = "SELECT * FROM user_profiles WHERE user_profile_name = '$a'";
          $cnt = mysql_num_rows(mysql_query($q));
          if($cnt > 0)
          {
             include("profile/profile.php");
             $flag = true;
          }
          
      }
      
  }
if($flag == false)
{
   include("home.php") // your index or homepage 
}

So above code I tried to find the uri and check it on database if username/profile name exists or not. If it found I include the profile page. if not then include the homepage. After including profile.php page, all variables (only above include) are available in profile.php file.

its working with me very well.

You may have better solutions. But I need it very urgent that’s why I write the code in this way. If you have better solution please share your thoughts.

passing get variable in cakephp pagination url

Tags

argument, CakePHP, GET, pagination, paginator, parameter passed, PHP

For searching we many need to pass variable like ?keyword=test, and we may need to add pagination withen the search, Here I describe multiple cases where we may need to use pagination and how we manage the url for pagination when we make some searching

Case 1: if the url like the following
http://www.mydomain.com/controller/method/?keyword=test1&opt=test2

In this case we need to add the paginator option like this
First we retrive the passing variable and assign value, we can get it from “$this->params[‘url’]

$urls = $this->params['url']; $getv = "";
foreach($urls as $key=>$value)
{
if($key == 'url') continue; // we need to ignor the url field
$getv .= urlencode($key)."=".urlencode($value)."&"; // making the passing parameters
}
$getv = substr_replace($getv ,"",-1); // remove the last char '&'

Now we have the all get parameter, lest assign this to paginator option

$paginator->options(array('url' => array("?"=>$getv)));

Now all the pagination links always taking this get parameter so now if we gos to the next page the url look like this
http://www.mydomain.com/controller/method/page:2?keyword=test1&opt=test2

Now If we need passing an argument as id like the following
http://www.mydomain.com/controller/method/1/?keyword=test1&opt=test2
where 1 is an id or something we get this 1 from $this->passedArgs[0] So now we have to set the paginator option like this

$paginator->options(array('url' => array($this->passedArgs[0],"?"=>$getv)));

If we have passed more than one argument, we need to take it

$pass_argument = $this->passedArgs[0]."/"$this->passedArgs[1]."/".$this->passedArgs[2]."/";
$paginator->options(array('url' => array($pass_argument,"?"=>$getv)));

It depend on you how much you want to passed the argument, if you faced any problem print the $this->passedArgs and see how it organize the argument. Its really easy and I’ve already used it. Cheers

–new update
I got the idea from comments, here is update, the following code will useful for multiple arguments or params.

//extract the get variables
$url = $this->params['url'];
unset($url['url']);
$get_var = http_build_query($url);

$arg1 = array(); $arg2 = array();
//take the named url
if(!empty($this->params['named']))
$arg1 = $this->params['named'];

//take the pass arguments
if(!empty($this->params['pass']))
$arg2 = $this->params['pass'];

//merge named and pass
$args = array_merge($arg1,$arg2);

//add get variables
$args["?"] = $get_var;

$paginator->options(array('url' => $args));

done.. But I’m trying to make better solution, will update it soon.
