Multilanguage CodeIgniter 3.0

In this tutorial we will implement multilanguage to CodeIgniter.

Site Default Language
Open the application/config/config.php file and specify the site’s default language.

$config['language']  = 'bulgarian';  //Language you want to be default

Language Files

The language files must be named with _lang suffix. For example, if you want to create a file containing site’s message translation then the file name might be message_lang.php.

Insert those files into the application/language/ directory with separate sub-directories for each language (for example, english, bulgarian, etc.).

Pagination example


  • «
  • $last){$top=$last;} if($x<=0){$bottom+=1;$top+=1;} } for($i=$bottom;$i<=$top;$i++){ ?>
  • ">
  • »


$(document).on("click",".pbutton",function() {
		var selected = this.text; //Selected page
		if(selected=="«"){selected = 1;} //first rows
		if(selected=="»"){selected = $(".last_page").attr("id");} //last rows
			command:"show_regular_quotation", //name of var: value of var  

The code is perfectly compatible with bootstrap.

Currency convertor with PHP

function currency_convert($amount, $from, $to){
	$result = file_get_contents("$amount&from=$from&to=$to");
	$result = explode("",$result);
	$result = explode("",$result[1]);  
	$converted_amount = preg_replace("/[^0-9\.]/", null, $result[0]);
	echo $converted_amount;


Function for getting random word from words in brackets

function randomWords($paragraph){ //get one from the words in {}
		preg_match_all('/{(.*?)}/s', $paragraph, $matches);
		foreach($matches[1] as $variations){
			$variations_array = explode('|',$variations);
			$paragraph = str_ireplace('{'.$variations.'}',$variations_array[array_rand($variations_array)],$paragraph);
		return $paragraph;

For example {traces | trails | spots}. Will return one of the words in brackets.

PHP function for downloading images from http

This function will download images from another site , resize them and put suffix (if needed).

function download_resized_jpeg($filename,$width,$height,$suffix){
	$name = explode('/',$filename);
	$newfilename = end($name);

	// Content type
	//header('Content-Type: image/jpeg');

	list($width_orig, $height_orig, $type) = getimagesize($filename);

	$ratio_orig = $width_orig/$height_orig;

	if ($width/$height > $ratio_orig) {
	   $width = $height*$ratio_orig;
	} else {
	   $height = $width/$ratio_orig;

	// Resample
	$image_p = imagecreatetruecolor($width, $height);
	if ($type == 1)
        $image = imagecreatefromgif($filename);
    elseif ($type == 2)
        $image = imagecreatefromjpeg($filename);
    elseif ($type == 3)
        $image = imagecreatefrompng($filename);
        $image = imagecreatefromwbmp($filename);
	if($type==1 or $type==3) //this code below should preserve transparency but I couldn't try it out for now...
        imagealphablending($image_p, false);
        imagesavealpha($image_p, true);
        imagecolortransparent($image_p, imagecolorallocatealpha($image_p, 0, 0, 0, 127));
	imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $width_orig, $height_orig);

	// Output
	if ($type == 1)
        imagegif ($image_p, "../pictures/$newfilename$suffix".".gif", 100);
    elseif ($type == 2)
        imagejpeg($image_p, "../pictures/$newfilename$suffix".".jpg", 100);
    elseif ($type == 3)
        imagepng ($image_p, "../pictures/$newfilename$suffix".".png", 0);
        imagewbmp ($image_p, "../pictures/$newfilename$suffix".".bmp", 100);

Cross domain access to data on the server PHP

If you are doing a ajax call to retrieve data from your own server on a platform which is set to prevent these ajax calls . To bypass “Access-Control-Allow-Origin” you need to allow cross domain access by including this in your server php code.

 header('Access-Control-Allow-Origin: *'); 

OR – for only one domain

 header('Access-Control-Allow-Origin: http//'); 

I hope this will help you gain access to you cross-domain data.
