Thinkphp5 uses the seeder in composerFeb 18, 2018 pm 02:08 PM
composerthinkphp5

Cause:

A few days ago, the customer asked to build a member question and answer system, so I followed the process. When it came time to call the database data, I felt that a It’s a bit stupid to add this~

Solution process:

After checking the manual and looking at foreign blog cases, I came up with a good method~~~

My usage record has been screenshot:

##Until the latter one displays the time, it means that the seeder is running successfully~

The following is the official process

Seeder Creation

In the Thinkphp5 project, we can enter the following command on the command line:

php think seed:create UserSeeder

Create a

UserSeeder file. After the creation is successful, you can database/seeds See below the directory:

database|-seeds
|-|-UserSeeder.php

The content is as follows:

<?phpuse think\migration\Seeder;class UserSeeder extends Seeder
{    /**
     * Run Method.
     *
     * Write your database seeder using this method.
     *
     * More information on writing seeders is available here:
     * http://docs.phinx.org/en/latest/seeding.html
     */    public function run()
    {

    }
}

The code is very simple, and a

run is given by default Method, now we all know that the seeder file is used to generate simulation data, and the code to generate simulation data can be written in the run method.

Seeder's run method

In the

run method, we can fill in any code that can fill the database. Here I will give you some ideas:

Requirements: Give the data table
Users to simulate and generate 100 pieces of data. The table structure is as follows:

FieldDescriptionnicknamepasswordAfter receiving the request, I can write like this:
nickname
##email<a href="http://www.php.cn/code/114.html" target="_blank"></a>EMAIL
Password
<?phpuse think\migration\Seeder;class UserSeeder extends Seeder
{    /**
     * Run Method.
     *
     * Write your database seeder using this method.
     *
     * More information on writing seeders is available here:
     * http://docs.phinx.org/en/latest/seeding.html
     */    public function run()
    {
        $rows = [];        for ($i = 0; $i < 100; $i++) {
            $rows[] = [                &#39;nickname&#39; => mt_rand(10000, 99999),                &#39;email&#39; => mt_rand(10000, 99999).&#39;@qq.com&#39;,                &#39;password&#39; => md5(&#39;123456&#39;),
            ];
        }        $this->table(&#39;users&#39;)->insert($rows)->save();
    }
}

Note: Be sure to call the
save()

method, otherwise it will not be saved.

First, I generated 100 pieces of data, and then called
$this->table('users')->insert($rows)->save();

Insert the generated data into the Users table of the database. Is not it simple? ^ - ^.Execute Seeder

After the Seeder file is defined, the data must be executed before it can be inserted into the database. We can execute it like this:

php think seed:run

Execute Success tip:

All Done. Took 0.0552s

. You can see:



##php think seed:run

mPDF

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
