HTML 表的 PHP 類別：奇怪的屬性分配

Question

在建立 HTML 表格的類別中，我有這個呈現表格的方法。除了某些條件下的 HTML 屬性分配之外，一切都正常運作（縮排、結束標籤、資料表示等）。當我設定單元格資料時，我會呼叫 setData() 來接收三個參數並像這樣使用它。注意我如何設定第三個參數（單元格屬性）：

方法定義：

public function setData(
        array $data,
        array $row_attributes = [],
        array $cell_attributes = []
    ): bool {
    // the code
}

通話：

$table->setData(
    $pagination->resultset,
    [], // row attributes
    array( // cell attributes
        array(), // row 1 (index 0)
        array( // row2 (index 1)
            ["id"=>"R2C1id"], // row 2, cell 1
            ["id"=>"R2C2id", "onclick"=>"R2C2_onclick();"], // row 2, cell 2
        ),
        array( // row 3
            [],
            [],
            ["id"=>"R3C3id", "selected"=>"selected"], // row 3, cell 3
            [],
            [],
            [],
            []
        )
    )
);

在此範例中，表格有七個欄位。

在這裡您將看到 HTML 輸出。注意第二行和第三行的單元格屬性：

<div class='table-body'>
    <div class='table-row'>
        <div class='table-row-cell'>1</div>
        <div class='table-row-cell'>Consumidor Final</div>
        <div class='table-row-cell'>Consumidor Final</div>
        <div class='table-row-cell'></div>
        <div class='table-row-cell'>1</div>
        <div class='table-row-cell'></div>
        <div class='table-row-cell'></div>
    </div>
    <div class='table-row'>
        <div class='table-row-cell' id='R2C1id'>2</div>
        <div class='table-row-cell' id='R2C2id' onclick='R2C2_onclick();'>Prueba SRL</div>
        <div class='table-row-cell' 0='Array' 1='Array'>Tu Prueba</div>
        <div class='table-row-cell' 0='Array' 1='Array'>12345678901</div>
        <div class='table-row-cell' 0='Array' 1='Array'>1</div>
        <div class='table-row-cell' 0='Array' 1='Array'></div>
        <div class='table-row-cell' 0='Array' 1='Array'></div>
    </div>
    <div class='table-row'>
        <div class='table-row-cell'>3</div>
        <div class='table-row-cell'>Otra Prueba SA</div>
        <div class='table-row-cell' id='R3C3id' selected='selected'>Prueba 2</div>
        <div class='table-row-cell'>12345678902</div>
        <div class='table-row-cell'>1</div>
        <div class='table-row-cell'></div>
        <div class='table-row-cell'></div>
    </div>
</div>

這是我用來完成這一切的程式碼。我將向您展示單元格渲染的程式碼片段以及處理屬性的方法。

儲存格渲染：

// process cells
        $row_counter = 0;
        foreach ($this->data as $data) { // row
            $row_build = "";
            $cell_counter = 0;
            foreach ($data as $cell_data) { // cell
                if ($cell_counter < $col_count) {
                    $row_build .= $this->getHtmlDiv(
                        $html_cell_class,
                        $cell_data ?? "",
                        $this->getHtmlAttributes("cell", $row_counter, $cell_counter),
                        3
                    );
                }
                $cell_counter ;
            }

            // $cell_counter ;

            // complete empty cells to preserve row:hover on full row
            while ($cell_counter < $col_count) {
                $row_build .= $this->getHtmlDiv(
                    $html_cell_class,
                    "",
                    $this->getHtmlAttributes("cell", $row_counter, $cell_counter),
                    3
                );
                $cell_counter ;
            }

            $body_build .= $this->getHtmlDiv(
                $html_row_class,
                $row_build,
                $this->getHtmlAttributes("row", $row_counter, 0),
                2,
                true
            );
            $row_counter ;
        }

屬性的方法：

private function getHtmlAttributes(string $section, int $row, int $column): array
{

    if (count($this->html_attributes[$section]) > 0) {
        if (array_key_exists($row, $this->html_attributes[$section])) {
            if ($section === "cell") {
                if (array_key_exists($column, $this->html_attributes[$section][$row])) {
                    return $this->html_attributes[$section][$row][$column];
                }
            }
            return $this->html_attributes[$section][$row];
        }
    }
    return [];
}

怎麼了？謝謝。

好吧，當我發布問題並選擇程式碼時，答案出現了。在方法 getHtmlAttributes() 中，缺少 else 條件。

private function getHtmlAttributes(string $section, int $row, int $column): array
{

    if (count($this->html_attributes[$section]) > 0) {
        if (array_key_exists($row, $this->html_attributes[$section])) {
            if ($section === "cell") {
                if (array_key_exists($column, $this->html_attributes[$section][$row])) {
                    return $this->html_attributes[$section][$row][$column];
                } else { // <-- this 
                    return [];
                }
            }
            return $this->html_attributes[$section][$row];
        }
    }
    return [];
}
