I need to add watermark to the existing image. Codeigniter provides such functionality under image_lib library. Based on the instruction given here , i have done. Fatal error is displaying instead of the result.
A PHP Error was encountered
Severity: Error
Message: Call to a member function watermark() on null
Filename: controllers/Imageman.php
Line Number: 22
Code is
$config['image_library'] = 'gd2';
$config['source_img']='images/images.jpg';
$config['wm_text']='Hi welcome..!';
$config['wm_type']='text';
$config['wm_font_path']='./system/fonts/texb.ttf';
$config['wm_font_size']='16';
$config['wm_font_color']='ffffff';
$config['wm_vrt_alignment']='bottom';
$config['wm_hor_alignment']='center';
$config['wm_padding']='20';
$this->load->library('Image_lib',$config);
$this->Image_lib->watermark();
if($this->Image_lib->watermark())
{
echo "Watermark added";
}
else
{
echo "Failed";
}
After looking at the documentation, it uses:
$config['source_image'] instead of $config['source_img']

I am migrating my existing PHP program to Laravel. I know the upload should be $request->files->store('images'); but this doesn't compress the images beforehand.
I have found Intervention Image plugin for Laravel but I don't want to use it because I want it to be pure PHP only.
My working code from pure PHP was:
$info = getimagesize($tmpFilename);
if ($info['mime'] == 'image/jpeg') {
$image = imagecreatefromjpeg($tmpFilename);
} else if ($info['mime'] == 'image/gif') {
$image = imagecreatefromgif($tmpFilename);
} else if ($info['mime'] == 'image/png') {
$image = imagecreatefrompng($tmpFilename);
}
imagejpeg($image, $path, 60);
I know the images get saved at /storage/app/public/ so I used that path for imagejpeg as well. This is my laravel code:
$tmp_file = $inner->getPathName();
imagejpeg($tmp_file, '/storage/app/public/images/hehe.jpg', 60);
But it doesn't work. It only says
imagejpeg(/storage/app/public/images/hehe.jpg): failed to open stream: No such file or directory
Any help would be appreciated
I'm using intervention/image module with laravel 4.2 , to upload images i'm using this code :
if (Input::hasFile('image'))
{
$file = Input::file('image');
$file->move('uploads/2/', $file->getClientOriginalName());
$image = Image::make(sprintf('uploads/2/%s', $file->getClientOriginalName()))->resize(120, 120)->save();
return 'yes';
}
With some images it works , with some images it produces this error :
imagecreatefromjpeg(): gd-jpeg, libjpeg: recoverable error: Premature end of JPEG file
switch ($info[2]) {
case IMAGETYPE_PNG:
$core = imagecreatefrompng($path);
$this->gdResourceToTruecolor($core);
break;
case IMAGETYPE_JPEG:
$core = imagecreatefromjpeg($path);
$this->gdResourceToTruecolor($core);
break;
This is because you upload corrupted images and GD can't handle that kind of images. Please check it in this issue .
Try to suppress this error like this.
ini_set('gd.jpeg_ignore_warning', true);
Hope it will be useful for you.
When i run my aaplication in external server i get eror ,
Message: Login::include_once(application/third_party/mpdf/mpdf.php) [function.Login-include-once]: failed to open stream: No such file or directory.
The same application was running perfect in local server. Can anyone please suggest what could be wrong with it. My controller function ,
function pdfapp() //for test run individually
{
$this->load->model('Registration_model');
$appno='4/SCSELB/2013/KL01';
$data['table'] = $this->Registration_model->getall_app($appno);
$data['own_land'] = $this->Registration_model->get_ownland($appno);
$data['loan_data'] = $this->Registration_model->getloan_data($appno);
$apppdf='4_SCSELB_2013_KL01';
$data['apppdf']=$apppdf;
$pdfFilePath = FCPATH."reports/application/$apppdf.pdf";
if (file_exists($pdfFilePath) == FALSE)
{
ini_set('memory_limit','32M');
$html = $this->load->view('pdf_report2', $data, true);
include_once APPPATH.'third_party/mpdf/mpdf.php';
$mpdf=new mPDF('c');
$mpdf->SetFooter(' copyright# KSDC'.'|{PAGENO}|'.'Applied on '.date('d-M-Y H.i.s'));
$mpdf->WriteHTML($html);
$mpdf->Output($pdfFilePath, 'F');
}
$this->load->view('pdf_report2',$data);
}
The error you're getting is of a file not existing, Did you you debug this line ?
APPPATH.'third_party/mpdf/mpdf.php'; ?
what path do you get if you var_dump it?
I am working on the log in system for a site using Flexi Auth in Codeigniter V 2.1.4. I am trying to pass a user's log in status to a menu that changes dynamically depending whether a user is logged in or not. This is the code i am using:
public function create_page($pgName = 'home')
{
$this->config->load('tera_site', TRUE);
$this->load->library('flexi_auth_lite');
// Cunstruct Page data
$data['pgName'] = $pgName;
if ($this->session->userdata('admin') === FALSE){$data['admin'] = 0;}else{$data['admin'] = $this->session->userdata('admin');}
$data['siteTitle'] = $this->config->item('siteTitle','tera_site');
// This is the line the Error is thrown from:
$data['loggedIn'] = $this->flexi_auth_lite->is_logged_in();
$data['header'] = $this->load->view('include/header', $data, TRUE);
$data['pages'] = $this->config->item('pages','tera_site');
$data['footer'] = $this->load->view('include/footer', False, TRUE);
$data['sideBar'] = $this->load->view('include/side_bar_view', $data, TRUE);
$this->load->model('page_model');
$data['pgData'] = $this->page_model->getPage($pgName);
// load the Catcha Library
$this->load->library('captcha_my');
if($data['pgData']['Captcha'] = 1) {
$data['Captcha'] = $this->captcha_my->createCaptcha();
} else if ($this->session->userdata('captchaCheck') == true) {
$data['Captcha'] = $this->captcha_my->createCaptcha();
}
return $data;
This is the error:
Severity: Notice
Message: Undefined property: Main::$flexi_auth_lite
Fatal error: Call to a member function is_logged_in() on a non-object
The code worked at one time, but even when it did it threw the same error when i called the function is_admen() from flexi_auth. Flexi_auth.php and Flexi_auth_lite.php are in application/libraries directory.
if you look into the demo files, there is a controller 'auth_lite.php'
it says
// IMPORTANT! This global must be defined BEFORE the flexi auth library is loaded!
// It is used as a global that is accessible via both models and both libraries, without it, flexi auth will not work.
$this->auth = new stdClass;
// Load 'lite' flexi auth library by default.
// If preferable, functions from this library can be referenced using 'flexi_auth' as done below.
// This prevents needing to reference 'flexi_auth_lite' in some files, and 'flexi_auth' in others, everything can be referenced by 'flexi_auth'.
$this->load->library('flexi_auth_lite', FALSE, 'flexi_auth');
I am trying to get the new PDO driver running in Code Igniter 2.1.1 in (to start with) the local (Mac OS 10.7) copy of my app.
I initially coded it using Active Record for all db operations, and I am now thinking I want to use PDO prepared statements in my model files, going forward.
I modified 'application/config/database.php' like so:
(note a couple minor embedded questions)
[snip]
$active_group = 'local_dev';
$active_record = TRUE;//<---BTW, will this need to stay TRUE to make CI sessions work? For better security, don't we want db-based CI sessions to use PDO too?
//http://codeigniter.com/user_guide/database/configuration.html:
//Note: that some CodeIgniter classes such as Sessions require Active Records be enabled to access certain functionality.
//this is the config setting that I am guessing (?) is my main problem:
$db['local_dev']['hostname'] = 'localhost:/tmp/mysql.sock';
// 1.) if $db['local_dev']['dbdriver']='mysql', then here ^^^ 'localhost:/tmp/mysql.sock' works, 2.) but if $db['local_dev']['dbdriver']='pdo', then it fails with error msg. shown below.
$db['local_dev']['username'] = 'root';
$db['local_dev']['password'] = '';
$db['local_dev']['database'] = 'mydbname';
$db['local_dev']['dbdriver'] = 'pdo';
$db['local_dev']['dbprefix'] = '';
$db['local_dev']['pconnect'] = TRUE;
$db['local_dev']['db_debug'] = TRUE;//TRUE
$db['local_dev']['cache_on'] = FALSE;
$db['local_dev']['cachedir'] = '';
$db['local_dev']['char_set'] = 'utf8';
$db['local_dev']['dbcollat'] = 'utf8_general_ci';
$db['local_dev']['swap_pre'] = '';
$db['local_dev']['autoinit'] = TRUE;
$db['local_dev']['stricton'] = FALSE;
[snip]
With the above config., as soon as I load a controller, I get this error message:
Fatal error: Uncaught exception 'PDOException' with message 'could not find driver' in
/Library/WebServer/Documents/system/database/drivers/pdo/pdo_driver.php:114 Stack trace: #0

I tried swapping out the 'pdo_driver.php' file from the one on github, as per this:
http://codeigniter.com/forums/viewthread/206124/
...but that just generates other errors, not to mention is disturbing to a newbie who does not want to touch the system files if at all possible.
This thread also seems to imply the need to be hacking the 'pdo_driver.php' system file:
CodeIgniter PDO database driver not working
It seems odd to me, though, that (someone thought that) a hack to a system file is needed to make PDO work in CI v.2.1.1, huh?
Thanks for any suggestions I can try.
I don't know if this might be helpful for you since you already started using the CI functions, but I made my own library for PDO with sqlite and just auto load it. My needs were simple, so it serves its purpose.

thanks to the noob thread http://codeigniter.com/forums/viewthread/180277/ (InsiteFX’s answer)..
I figured out the below seems to work (need to test more to be 100%... but at least the error messages are gone:
$db['local_dev']['hostname'] = 'mysql:host=127.0.0.1';
