You often need an action link to activate or deactivate a plugin. How do you do that? I have written a simple function that can help you achieve this.

'&plugin=%s&plugin_status=all&paged=1&s' ), $plugin ); $_REQUEST['plugin'] = $plugin; $url = wp_nonce_url( $url, $action . '-plugin_' . $plugin ); return $url; } |
How to use? This function requires 2 parameters; first one is the plugin file name, and second one is action type. Plugin file name is…

A beautiful and nicely crafted theme can change the look and feel of your WordPress site. But, what about the login page? Default login page is too ordinary to attract your visitors. Although this can be handled with a custom login page, but most of the themes does not include this feature. Here I’m going…
Update: I have released Ncrypt, a library (OOP based) that facilitates the same (two-way encryption and decryption). See here This function will provide you a two-way system to encrypt a string or decrypt an encrypted string.
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 | /** * Encrypt and decrypt * * @author Nazmul Ahsan <n.mukto@gmail.com> * @link http://nazmulahsan.me/simple-two-way-function-encrypt-decrypt-string/ * * @param string $string string to be encrypted/decrypted * @param string $action what to do with this? e for encrypt, d for decrypt */ function my_simple_crypt( $string, $action = 'e' ) { // you may change these values to your own $secret_key = 'my_simple_secret_key'; $secret_iv = 'my_simple_secret_iv'; $output = false; $encrypt_method = "AES-256-CBC"; $key = hash( 'sha256', $secret_key ); $iv = substr( hash( 'sha256', $secret_iv ), 0, 16 ); if( $action == 'e' ) { $output = base64_encode( openssl_encrypt( $string, $encrypt_method, $key, 0, $iv ) ); } else if( $action == 'd' ){ $output = openssl_decrypt( base64_decode( $string ), $encrypt_method, $key, 0, $iv ); } return $output; } |
