PHP and Jquery Utilities

[sylvain86]

For person who wants PHP functions :

Crop JPG image :

<?php
function resize($imgFile,$output, $width, $height, &$error = null) {
       $attrs = @getimagesize($imgFile);
       if($attrs == false or $attrs[2] != IMG_JPEG)
       {
          $error = "Uploaded image is not JPEG or is not readable by this page.";
          return false;
       }
       if($attrs[0] * $attrs[1] > 3000000)
       {
          $error = "Max pixels allowed is 3,000,000. Your {$attrs[0]} x " .
                   "{$attrs[1]} image has " . $attrs[0] * $attrs[1] . " pixels.";
          return false;
       }
       $ratio = (($attrs[0] / $attrs[1]) < ($width / $height)) ?
                $width / $attrs[0] : $height / $attrs[1];
       $x = max(0, round($attrs[0] / 2 - ($width / 2) / $ratio));
       $y = max(0, round($attrs[1] / 2 - ($height / 2) / $ratio));
       $src = imagecreatefromjpeg($imgFile);
       if($src == false)
       {
          $error = "Unknown problem trying to open uploaded image.";
          return false;
       }
       $resized = imagecreatetruecolor($width, $height);
       $result = imagecopyresampled($resized, $src, 0, 0, $x, $y, $width, $height,
                 round($width / $ratio, 0), round($height / $ratio));
       if($result == false)
       {
          $error = "Error trying to resize and crop image.";
          return false;
       }
       else
       {
          imagejpeg($resized,$output,100);
       }
    }
?>

For Adblock detection:

Here's the code:

document.write('<div id="checker">an advertisement</div>');

Now, if Adblock check this, detection will be ready.

Add a CSS:

#checker {
    display:none;
}

If you use JQUERY, let's see the code to display something :

var REGISTER = '{YOUR_SITE_URL}';
var REQUEST = location.href;
function message(type,message,timeval,redirect) {
    if(type == 1) {
        var myclass = 'alert alert-success';
        var title = 'OK';
    }
    else {
        var myclass = 'alert-danger alert-error';
        var title = 'ERREUR';
    }
    bootbox.alert('<div class="'+myclass+'" style="padding:10px;"><h2>'+title+'</h2><p>'+message+'</p></div>');
    setTimeout(function() {
        bootbox.hideAll();
        if(redirect) {
            if(redirect=='back')
                history.back();
            else
                location.href = redirect;
        }
    }, timeval*1000);
}
$(document).ready(function() {
    if(document.getElementById("checker") == undefined && !REQUEST.match('inscription')) {
        message(0,"<u>It seems that <b>ADBLOCK</b> is activated on your browser</u>. Just deactivate it or <a href='"+REGISTER+"'>Subescrive</a>. You're going to be redirected... ",10,REGISTER);
    }
});

In this case I use jquery, bootstrap et bootbox.

If you wanna simplier:

$(document).ready(function() {
    if(document.getElementById("checker") == undefined ) {
        location.href = 'anti-adblock.php'
    }
});

Or display a message.
