在表格內張貼PHP數據

Question

在以下代碼中，問題是隱藏輸入字段（名爲「res_id」）的值將固定到表的第一行。知道我在這裏運行一個foreach循環來生成res_id字段的值，我期望每次foreach循環開始時都有唯一的值。請注意表格數據字段或<td>呈現正確的值。換句話說，如果我嘗試在動作php頁面中回顯res_id的POST值，它將保持相同的值！希望我清楚。非常感激你的幫助。

包括行計數器在foreach循環或使用一個唯一的ID的每一行從另一個來源

$i_rowcount++; 

名稱輸入字段這樣的，所以你必須在你的帖子值的行ID作爲數組索引鍵。

<input type="hidden" name="resid[$i_rowcount]" value="your value"> 

結果將是，你有當你點擊後，看起來像這樣

resid 
1 => value of first row 
2 => value of second row 
... 

，並在情況下，你要修復您的選擇字段的值的數組，這樣做同樣的way

$a_options = array(1 => 'Very Good', 
        2 => 'Good', 
        3 => 'Average'); 

echo '<select name="selected_quality[$i_rowcount]"style="color:blue;">'; 
foreach($a_options as $i_key => $s_value){ 
echo '<option'.($_POST['selected_quality'][$i_rowcount] == $i_key ? ' selected="selected"' : '').' value="'.$i_key.'">'.$s_value.'</option>'; 
} 
echo '</select>';
