How to fix You can also run `php --ini` inside terminal to see which files are used by PH P in CLI mode

You have any problem with this since install laravel with composer install, let's see

  Problem 1
    - intervention/image 2.4.0 requires ext-fileinfo * -> the requested PHP exte
nsion fileinfo is missing from your system.

  To enable extensions, verify that they are enabled in your .ini files:
    - F:\xampp\php\php.ini
  You can also run `php --ini` inside terminal to see which files are used by PH
P in CLI mode.



This you must to go to your php.ini and edit it in commented line:
; Laravel drop comment
extension=php_fileinfo.dll

drop the comment in
;extension=php_fileinfo.dll
to be
extension=php_fileinfo.dll

Then save it and go again with composer install in you directory with terminal or cmd

How To Make String, Char, Varchar To be Auto Increment in MySQL with PHP

Making varchar or string or char to be automatically add as auto increment, is't impossible?

Yah inilah yang dicari-cari selama ini jika anda ingin menambahkan atau membuat primary key dalam table dari tipe data char/ varchar/ string lalu ingin menjadikannya otomatis layaknya auto increment, berikut ini adalah salah satu contoh jika anda membuat primary key secara otomatis menambahkan kode sesuai dengan keinginan kita atau sering disebut dengan custom.

Kita asumsikan membuat ini dengan Framework dengan memiliki 1 tabel dengan format berikut:

CREATE TABLE `tb_supplier` (
  `id_supplier` char(5) NOT NULL,
  `nm_supplier` varchar(20) DEFAULT NULL,
  `no_hp` varchar(12) DEFAULT NULL,
  `email` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`id_supplier`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

-- ----------------------------
-- Records of tb_supplier
-- ----------------------------
INSERT INTO `tb_supplier` VALUES ('S0001', 'Supervisor', '1238123', 'email@gmail.com');
INSERT INTO `tb_supplier` VALUES ('S0002', 'minyak', '08998600083', 'justpoypoy@gmail.com');

kemudian buatlah sebuah class dalam Models seperti ini

function kodebaru() {
        $q = $this->db->query("SELECT id_supplier, substr(id_supplier, 2, 4) as id_baru FROM tb_supplier ORDER BY id_supplier DESC LIMIT 1") -> row();
        if(!empty($q)){
            $f = str_replace($q->id_supplier, 'S', '5.'.$q->id_baru);
            $b = (float)$f+0.0001;
            if(strlen(utf8_decode($b))==6){
                $k = substr($b,2,4);
            }else if(strlen(utf8_decode($b))==5){
                $t = str_replace($b, $b, $b.'0');
                $k = substr($t,2,4);
            }else if(strlen(utf8_decode($b))==4){
                $t = str_replace($b, $b, $b.'00');
                $k = substr($t,2,4);
            }else if(strlen(utf8_decode($b))==3){
                $t = str_replace($b, $b, $b.'000');
                $k = substr($t,2,4);
            }else{
                $k = 'err';
            }
         
            $kb = 'S'.$k;
        }else{
            $kb = 'S0001';
        }
        return $kb;
        }



Setelah itu masukkan dalam Controllers

          $this->data['row']   = $this -> M_supplier -> kodebaru();
          $this -> load -> view('your template',$this -> data);


Yang paling terakhir masukkan dalam Views untuk form tambah atau Add seperti ini

                ID Supplier *
               



Dan hasilnya pasti akan sesuai dengan format yang ada, alasan kenapa menggunakan float yaitu titik beratnya pada banyaknya nol yang harus selalu ada. jika dirubah dengan integer maka nol tersebut akan hilang, kemudian ada rules tambahan yang membuatnya sempurna.
Semoga dapat bermanfaat.

Cara Memasang Keywords dengan Meta di Blogger

Sebenernya mesin pencari sudah tidak lagi menggunakan meta keywords sebagai salah satu faktor penentu rangking. Tapi bagi sobat yang tetap kepengin memasang meta keywords di blogger, di bawah ini adalah tutorialnya. Ada dua jenis meta keywords yang bisa digunakan di blogger. Pertama meta keywords otomatis dan yang kedua meta keywords manual.

Cara memasang meta keywords otomatis
<b:if cond='data:blog.homepageUrl == data:blog.url'><meta expr:content='data:blog.title' name='keywords'/></b:if>
<b:if cond='data:blog.pageType == &quot;item&quot;'><meta expr:content='data:blog.pageName' name='keywords'/></b:if>
Cara memasang meta keywords manual
<b:if cond='data:blog.homepageUrl == data:blog.url'>
<meta content='Katakunci1, Katakunci1, Katakunci1' name='keywords'/>
</b:if>
<b:if cond='data:blog.pageType == &quot;item&quot;'>
<meta content='Katakunci2, Katakunci2, Katakunci2' name='keywords'/>
</b:if>

• Ganti Katakunci1 dengan kata kunci untuk halaman depan blog sobat

• Ganti Katakunci2 dengan kata kunci untuk halaman postingan blog sobat

Jika menggunakan cara di bawah ini, kata kunci pada meta keywords akan otomatis mengambil dari judul blog dan juga judul postingan.

#1. Login ke blogger.com dan masuk ke dashboard blog sobat.

#2. Klik menua “Template”

#3. Klik “Edit HTML”

#4. Letakan kode di bawah ini tepat di bawah kode <head>:

#5. Jika sudah, klik “Simpan template”

Meta keywords manual

Meta keywords manual artinya sobat harus memasukan kata kunci secara manual pada kode meta keywords.

#1. Login ke blogger.com dan masuk ke dashboard blog sobat.

#2. Klik menua “Template”

#3. Klik “Edit HTML”

#4. Letakan kode di bawah ini tepat di bawah kode <head>

<b:if cond='data:blog.homepageUrl == data:blog.url'>
 <meta content='Katakunci1, Katakunci1, Katakunci1' name='keywords'/>
</b:if>    
<b:if cond='data:blog.pageType == &quot;item&quot;'>
 <meta content='Katakunci2, Katakunci2, Katakunci2' name='keywords'/>
</b:if>

#5. Jika sudah, klik “Simpan template”

Begitulah kira-kira tutorial mudah dan nggak pakai ribet tentang cara memasang meta keywords di blogger.com. Mudah-mudahan bermanfaat.
