“Fatal error: Class not found in..”, Composer pack

问题:

I ran this call in Putty, it successfully installed the resource:

php composer.phar require --dev "mikehaertl/php-pdftk:*"

I then added a couple of thing to my composer.json:

{
    "name": "you/bootstrap-canvas-wp",
    "type": "wordpress-theme",
    "require": {
        "composer/installers": "~1.0"
    },
    "require-dev": {
        "mikehaertl/php-pdftk": "*"
    },
    "extra": {
        "installer-paths": {
            "wp-content/themes/bootstrap-canvas-wp/": ["type:wordpress-theme"]
        }
    }
}

Next I ran an update command on my composer file:

php composer.phar update

I have a file located inside that theme folder /public_html/wp-content/themes/bootstrap-canvas-wp that has this code:

use \mikehaertl\pdftk\Pdf;

$pdf = new Pdf('mypdf.pdf');
$pdf->flatten()
    ->saveAs('mypdf2.pdf');

Finally, I placed this piece of code in my functions.php file inside the theme folder in an effort to make these classes usable:

require_once(ABSPATH. '../vendor/autoload.php');

My code editor recognizes these resources but I get an error in my browser:

Fatal error: Class 'mikehaertl\pdftk\Pdf' not found in /home/myusername/public_html/wp-content/themes/bootstrap-canvas-wp/flattenPDF.php on line 1

Any suggestions on how to make this functional?

EDIT: I've also tried this syntax for the use statement: (same error happens)

use mikehaertl\pdftk\Pdf;

回答1:

I got the same error when autoload was not called correctly. What solved for me is:

require_once('vendor/autoload.php');

I use this in plain php project,the php page where i use it it is the same folder as the mikehaertl folder. So i am sure that your issue is related to this
