Field display

HTML

The html method allows you to insert a piece of HTML code without displaying label on the details page

// pass in string
$show->html('<br/>');
// pass in view
$show->html(view(...));
// incoming closures
$show->html(function () {
    // Get field information
    $id = $this->id;
    $username = $this->username;
    return view(..., ['id' => $id]);
});

Dividers

If a separator line is to be added between fields.

$show->divider();

Line feed

If you want to use line feeds between fields.

$show->newline();

Modify display content

Modify the display using the following methods

$show->title()->as(function ($title) {
    // Get other fields of the current row
    $username = $this->username;
    return "<{$title}> {$username}";
});
$show->contents()->as(function ($content) {
    return "<pre>{$content}</pre>";
});

Ways to help

The help method is used in the same way as the data form field help method, see [Help Method] (model-grid-column.md#help).

Built-in Display Extension Methods

Here are a few common display styles that are built in as methods:

view

The view method can introduce a view file.

// The following three variables are received in the template:
// name field name
// value field value
// model Current row data
$show->content->view('admin.fields.content');

explode

The explode method splits the string into arrays.

$show->tag->explode()->label();
// You can specify delimiter, default ",".
$show->tag->explode('|')->label();

prepend

The prepend method is used to insert content in front of a value of type string or array.

// When the value of a field is a string
$show->email->prepend('mailto:');
// When the value of a field is an array
$show->arr->prepend('first item');

The prepend method allows passing parameters to closures

$show->email->prepend(function ($value, $original) {
    // $value is the current field value
    // $original is the original value of the current field as queried from the database.
    // Get other field values
    $username = $this->username;
    return "[{$username}]";
});

append

The append method is used to insert content after a value of type string or array.

// When the value of a field is a string
$show->email->append('@gmail.com');
// When the value of a field is an array
$show->arr->append('last item');

The append method allows passing parameters to closures

$show->email->append(function ($value, $original) {
    // $value is the current field value
    // $original is the original value of the current field as queried from the database.
    // Get other field values
    $username = $this->username;
    return "[{$username}]";
});

image

The content of the field avatar is the path or url of the image, which can be displayed as the image.

$show->avatar()->image();

The parameters of the image() method refer to Field::image().

file

The content of the field document is the path or url of a file, which can be displayed as a file.

$show->avatar()->file();

The arguments of the file() method refer to Field::file().

link

The content of the field homepage is the url link, which can be displayed as an HTML link.

$show->homepage()->link();

The arguments of the link() method refer to Field::link()

label

Display the contents of the field tag as label.

$show->tag()->label();

The arguments of the label() method refer to Field::label().

badge

Display the contents of the field rate as badge.

$show->rate()->badge();

The arguments of the badge() method are referenced in Field::badge().

using

If the field gender takes the values f and m, it needs to be displayed as female and male respectively.

$show->gender()->using(['f' => '女', 'm' => '男']);

dot

Column text can be preceded by a colored dot using the dot method.

use Dcat\Admin\Admin;
$show->state
    ->using([1 => 'Unprocessed', 2 => 'Processed', ...])
    ->dot(
        [
            1 => 'primary',
            2 => 'danger',
            3 => 'success',
            4 => Admin::color()->info(),
        ], 
        'primary' // The second parameter is the default value.
    );

Display file size

If the field data is a number of bytes representing the size of the file, you can display more readable text by calling the filezise method

$show->field('file_size')->filesize();

This value 199812019 will show 190.56 MB.
