HTML テーブルクラス

The Table Class provides functions that enable you to auto-generate HTML tables from arrays or database result sets.

テーブルクラスの使い方

クラスの初期化

Like most other classes in CodeIgniter, the Table class is initialized in your controller using the $this->load->library() method:

$this->load->library('table');

Once loaded, the Table library object will be available using:

$this->table

Here is an example showing how you can create a table from a multi-dimensional array. Note that the first array index will become the table heading (or you can set your own headings using the set_heading() method described in the function reference below).

$this->load->library('table');

$data = array(
        array('Name', 'Color', 'Size'),
        array('Fred', 'Blue', 'Small'),
        array('Mary', 'Red', 'Large'),
        array('John', 'Green', 'Medium')
);

echo $this->table->generate($data);

Here is an example of a table created from a database query result. The table class will automatically generate the headings based on the table names (or you can set your own headings using the set_heading() method described in the class reference below).

$this->load->library('table');

$query = $this->db->query('SELECT * FROM my_table');

echo $this->table->generate($query);

Here is an example showing how you might create a table using discrete parameters:

$this->load->library('table');

$this->table->set_heading('Name', 'Color', 'Size');

$this->table->add_row('Fred', 'Blue', 'Small');
$this->table->add_row('Mary', 'Red', 'Large');
$this->table->add_row('John', 'Green', 'Medium');

echo $this->table->generate();

Here is the same example, except instead of individual parameters, arrays are used:

$this->load->library('table');

$this->table->set_heading(array('Name', 'Color', 'Size'));

$this->table->add_row(array('Fred', 'Blue', 'Small'));
$this->table->add_row(array('Mary', 'Red', 'Large'));
$this->table->add_row(array('John', 'Green', 'Medium'));

echo $this->table->generate();

テーブルの見かけを変更する

The Table Class permits you to set a table template with which you can specify the design of your layout. Here is the template prototype:

$template = array(
        'table_open'            => '<table border="0" cellpadding="4" cellspacing="0">',

        'thead_open'            => '<thead>',
        'thead_close'           => '</thead>',

        'heading_row_start'     => '<tr>',
        'heading_row_end'       => '</tr>',
        'heading_cell_start'    => '<th>',
        'heading_cell_end'      => '</th>',

        'tbody_open'            => '<tbody>',
        'tbody_close'           => '</tbody>',

        'row_start'             => '<tr>',
        'row_end'               => '</tr>',
        'cell_start'            => '<td>',
        'cell_end'              => '</td>',

        'row_alt_start'         => '<tr>',
        'row_alt_end'           => '</tr>',
        'cell_alt_start'        => '<td>',
        'cell_alt_end'          => '</td>',

        'table_close'           => '</table>'
);

$this->table->set_template($template);

注釈

You’ll notice there are two sets of “row” blocks in the template. These permit you to create alternating row colors or design elements that alternate with each iteration of the row data.

You are NOT required to submit a complete template. If you only need to change parts of the layout you can simply submit those elements. In this example, only the table opening tag is being changed:

$template = array(
        'table_open' => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">'
);

$this->table->set_template($template);

You can also set defaults for these in a config file.

class CI_Table
$function = NULL

Allows you to specify a native PHP function or a valid function array object to be applied to all cell data.

$this->load->library('table');

$this->table->set_heading('Name', 'Color', 'Size');
$this->table->add_row('Fred', '<strong>Blue</strong>', 'Small');

$this->table->function = 'htmlspecialchars';
echo $this->table->generate();

In the above example, all cell data would be ran through PHP’s htmlspecialchars() function, resulting in:

<td>Fred</td><td>&lt;strong&gt;Blue&lt;/strong&gt;</td><td>Small</td>
generate([$table_data = NULL])
パラメータ:
  • $table_data (mixed) – Data to populate the table rows with
返り値:

HTML table

返り値の型:

string

Returns a string containing the generated table. Accepts an optional parameter which can be an array or a database result object.

set_caption($caption)
パラメータ:
  • $caption (string) – Table caption
返り値:

CI_Table instance (method chaining)

返り値の型:

CI_Table

Permits you to add a caption to the table.

$this->table->set_caption('Colors');
set_heading([$args = array()[, ...]])
パラメータ:
  • $args (mixed) – An array or multiple strings containing the table column titles
返り値:

CI_Table instance (method chaining)

返り値の型:

CI_Table

Permits you to set the table heading. You can submit an array or discrete params:

$this->table->set_heading('Name', 'Color', 'Size');

$this->table->set_heading(array('Name', 'Color', 'Size'));
add_row([$args = array()[, ...]])
パラメータ:
  • $args (mixed) – An array or multiple strings containing the row values
返り値:

CI_Table instance (method chaining)

返り値の型:

CI_Table

Permits you to add a row to your table. You can submit an array or discrete params:

$this->table->add_row('Blue', 'Red', 'Green');

$this->table->add_row(array('Blue', 'Red', 'Green'));

If you would like to set an individual cell’s tag attributes, you can use an associative array for that cell. The associative key data defines the cell’s data. Any other key => val pairs are added as key=’val’ attributes to the tag:

$cell = array('data' => 'Blue', 'class' => 'highlight', 'colspan' => 2);
$this->table->add_row($cell, 'Red', 'Green');

// generates
// <td class='highlight' colspan='2'>Blue</td><td>Red</td><td>Green</td>
make_columns([$array = array()[, $col_limit = 0]])
パラメータ:
  • $array (array) – An array containing multiple rows’ data
  • $col_limit (int) – Count of columns in the table
返り値:

An array of HTML table columns

返り値の型:

array

This method takes a one-dimensional array as input and creates a multi-dimensional array with a depth equal to the number of columns desired. This allows a single array with many elements to be displayed in a table that has a fixed column count. Consider this example:

$list = array('one', 'two', 'three', 'four', 'five', 'six', 'seven', 'eight', 'nine', 'ten', 'eleven', 'twelve');

$new_list = $this->table->make_columns($list, 3);

$this->table->generate($new_list);

// Generates a table with this prototype

<table border="0" cellpadding="4" cellspacing="0">
<tr>
<td>one</td><td>two</td><td>three</td>
</tr><tr>
<td>four</td><td>five</td><td>six</td>
</tr><tr>
<td>seven</td><td>eight</td><td>nine</td>
</tr><tr>
<td>ten</td><td>eleven</td><td>twelve</td></tr>
</table>
set_template($template)
パラメータ:
  • $template (array) – An associative array containing template values
返り値:

TRUE on success, FALSE on failure

返り値の型:

bool

Permits you to set your template. You can submit a full or partial template.

$template = array(
        'table_open'  => '<table border="1" cellpadding="2" cellspacing="1" class="mytable">'
);

$this->table->set_template($template);
set_empty($value)
パラメータ:
  • $value (mixed) – Value to put in empty cells
返り値:

CI_Table instance (method chaining)

返り値の型:

CI_Table

Lets you set a default value for use in any table cells that are empty. You might, for example, set a non-breaking space:

$this->table->set_empty("&nbsp;");
clear()
返り値:CI_Table instance (method chaining)
返り値の型:CI_Table

Lets you clear the table heading and row data. If you need to show multiple tables with different data you should to call this method after each table has been generated to clear the previous table information. Example:

$this->load->library('table');

$this->table->set_heading('Name', 'Color', 'Size');
$this->table->add_row('Fred', 'Blue', 'Small');
$this->table->add_row('Mary', 'Red', 'Large');
$this->table->add_row('John', 'Green', 'Medium');

echo $this->table->generate();

$this->table->clear();

$this->table->set_heading('Name', 'Day', 'Delivery');
$this->table->add_row('Fred', 'Wednesday', 'Express');
$this->table->add_row('Mary', 'Monday', 'Air');
$this->table->add_row('John', 'Saturday', 'Overnight');

echo $this->table->generate();
