HTML 表的 PHP 类:奇怪的属性分配

<p>在构建 HTML 表格的类中,我有这个呈现表格的方法。除了某些条件下的 HTML 属性分配之外,一切都工作正常(缩进、结束标签、数据表示等)。当我设置单元格数据时,我调用 setData() 来接收三个参数并像这样使用它。注意我如何设置第三个参数(单元格属性):</p> <p><strong>方法定义:</strong></p> <pre class="brush:php;toolbar:false;">public function setData( array $data, array $row_attributes = [], array $cell_attributes = [] ): bool { // the code }</pre> <p><strong>通话:</strong></p> <pre class="brush:php;toolbar:false;">$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 [], [], [], [] ) ) );</pre> <p>在此示例中,表格有七列。</p> <p>在这里您将看到 HTML 输出。注意第二行和第三行的单元格属性:</p> <pre class="brush:php;toolbar:false;"><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>

    好吧,当我发布问题并选择代码时,答案出现了。在方法 getHtmlAttributes() 中,缺少 else 条件。

    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 [];
    }
