Grid Column
By default, the column shows the most primitive data in the database. If you need to modify the display of the column data, refer to the following method.
Display callback
The display() method is used to process the value of the current column via the passed callback function:
$grid->column('title')->display(function ($title) {
Return "<span style='color:blue'>$title</span>";
});In the incoming anonymous function, the data can be processed in any way. In addition, the anonymous function binds the data of the current column as a parent object, and can call the data of the current row in the function:
$grid->column('first_name');
$grid->column('last_name');
// `full_name` field that does not exist
$grid->column('full_name')->display(function () {
Return $this->first_name . ' ' . $this->last_name;
});Display different components according to conditions
If this column is to be displayed as a different component based on certain criteria
$grid->column('title')->display(function ($title, $column) {
/ / If the value of the status field of this column is equal to 1, directly display the title field
If ($this->status == 1) {
Return $title;
}
// Otherwise it is displayed as editable
Return $column->editable();
});Content Mapping
If the value of the field gender is f, m, it needs to be displayed with female and male respectively.
$grid->column('gender')->using(['f' => 'female', 'm' => 'male']);Content replacement
If you need to replace some of the values of this column with other content to display:
$grid->column('cost')->replace([0 => '-']);Column view
Use the view() method to make the current column render a view display output, such as having a view resources/views/content.blade.php
<p>
{{ $value }}
{{ $model->id }}
</p>By default, two variables of the view are passed in, $model is the model of the current row, and $value is the value of the current column.
Then use the following call to render this view output
$grid->column('content')->view('content');This method can be used to render complex column content.
Column expansion
If there are more fields in a row, you can hide too much content by using the column expansion feature. Expand the display by clicking on the column, or click to expand other related data, such as the following example, to expand the 10 latest comments under an article:
Use Ezadev\Admin\Widgets\Table;
$grid->column('title', 'title')->expand(function ($model) {
$comments = $model->comments()->take(10)->map(function ($comment) {
Return $comment->only(['id', 'content', 'created_at']);
});
Return new Table(['ID', 'content', 'release time'], $comments->toArray());
});Any content that can be rendered can be returned in the closure function.
Popup modal box
Similar to the column expansion function, you can display more content by popping up the modal box.
$grid->column('title', 'title')->modal('latest comment', function ($model) {
$comments = $model->comments()->take(10)->get()->map(function ($comment) {
Return $comment->only(['id', 'content', 'created_at']);
});
Return new Table(['ID', 'content', 'release time'], $comments->toArray());
});Gavatar
If this column of data is a email, you want to display it as a Gavatar:
$grid->column('email', 'avatar')->gravatar();
// set the size
$grid->column('email', 'avatar')->gravatar(45);File size
If the data in this column is the number of bytes representing the file size, you can display the more readable text by calling the filezise method.
$grid->column('file_size')->filesize();Such a value 199812019 will be displayed as 190.56 MB
Download link
If the data in this column stores the path to the uploaded file, you can set this column as a downloadable link by calling the downloadable method.
$grid->column('file_path')->downloadable();Copy button
With the following call, a copy icon will appear in front of each line of text in this column, click on it to copy its value
$grid->column('title')->copyable();QR code
Through the following call, a QR code icon will appear in front of each line of text in this column. Click on it to expand a small bullet box, which will display the QR code of this column value.
$grid->column('link')->qrcode();Display image
If the picture field holds the full address of the picture, or the path, the column can be rendered as a picture display in the following way.
Multi-graph display is supported, and field output is required as an array.
$grid->column('picture')->image();
/ / Set the server and width
$grid->column('picture')->image('http://xxx.com', 100, 100);

Return json_decode($pictures, true);
})->image('http://xxx.com', 100, 100);Display label

]);Show icon

Display the field as a table, requiring the value of the current column to be a two-dimensional array
/ / table method does not pass parameters, the title of the table is the key of each column of the two-dimensional array
