HTML to PDF conversion with external CSS support in Codeigniter

Finally i fixed the bug. The problem is loading image inside the view page. Here i am adding header with Company name and logo.

http://domain.com/assets/other_uploads/photo/photo.png

If i give the above source in image URL, it tries to load the image in my view page and it fails. So, i used the below code to fix this.

var/www/domain/assets/other_uploads/photo/photo.png

For external css issue, i added the css part in view page as internal css.

It works now!!!

function WriteHTML($html,$bi)    {        //remove all unsupported tags        $this->bi=$bi;        if ($bi)            $html=strip_tags($html,"<a><img><p><br><font><tr><blockquote><h1><h2><h3><h4><pre><red><blue><ul><li><hr><b><i><u><strong><em>");         else            $html=strip_tags($html,"<a><img><p><br><font><tr><blockquote><h1><h2><h3><h4><pre><red><blue><ul><li><hr>");         $html=str_replace("\n",' ',$html); //replace carriage returns with spaces        // debug        if ($this->debug) { echo $html; exit; }        $html = str_replace('™','™',$html);        $html = str_replace('©','©',$html);        $html = str_replace('€','€',$html);        $a=preg_split('/<(.*)>/U',$html,-1,PREG_SPLIT_DELIM_CAPTURE);        $skip=false;        foreach($a as $i=>$e)        {            if (!$skip) {                if($this->HREF)                    $e=str_replace("\n","",str_replace("\r","",$e));                if($i%2==0)                {                    // new line                    if($this->PRE)                        $e=str_replace("\r","\n",$e);                    else                        $e=str_replace("\r","",$e);                    //Text                    if($this->HREF) {                        $this->PutLink($this->HREF,$e);                        $skip=true;                    } else                         $this->Write(5,stripslashes(txtentities($e)));                } else {                    //Tag                    if (substr(trim($e),0,1)=='/')                        $this->CloseTag(strtoupper(substr($e,strpos($e,'/'))));                    else {                        //Extract attributes                        $a2=explode(' ',$e);                        $tag=strtoupper(array_shift($a2));                        $attr=array();                        foreach($a2 as $v) {                            if(preg_match('/([^=]*)=["\']?([^"\']*)/',$v,$a3))                                $attr[strtoupper($a3[1])]=$a3[2];                        }                        $this->OpenTag($tag,$attr);                    }                }            } else {                $this->HREF='';                $skip=false;            }        }    }
