Question

我正在创建一个用户可以输入成分然后保存数量的系统，我使用PHP将其保存为XML。

它目前会像这样保存。

 <ingredients>
    <ingredient quantity="2">Apple</ingredient>
    <ingredient quantity="4">Banana</ingredient>
  </ingredients>

相反，我想像这样保存它，但我无法弄清楚如何。

  <ingredient>
            <quantity_amount>2</tns:quantity_amount>
            <quantity_name>teaspoons</tns:quantity_name>
            <ingredient_name>baking powder</tns:ingredient_name>
        </ingredient>

添加每种成分

这是我目前使用的PHP和HTML。

HTML

  <div id="addIngredient">
                <p>
                <input type="text" id="ingredient_1" name="ingredient[]" value="" placeholder="Ingredient"/>
                <input type="text" id="quantity_1" name="quantity[]"  value="" placeholder="Quantity"/>
                <a href="#" id="addNewIngredient">Add</a>
                </p>

                </div>

PHP

// Start for loop, from 0 to ingredientName
for ($i = 0; $i < count($ingredientName); $i++) {
    // Select current item
    $element = $ingredientName[$i];

    // Updated used ingredients list ONLY
    // if the ingredient wasn't added yet
    $temp = search($upIngreds, 'value', $element);
    if (empty($temp)) {
        $upIngreds[] = array('value' => $element, 'label' => $element, 'image' => 'images/products/default.jpg');
    }

    // Select current item quantity
    $qty = $quantity[$i];
    // Create ingredient element and fill with $element
    $ingredient = $xml->createElement('ingredient', $element);
    // Set quantity attiribute to $qty value
    $ingredient->setAttribute('quantity', $qty);
    // Append it to ingredients element
    $ingredients->appendChild($ingredient);
}

根据您所需的XML结构创建新成分：

// creating the document and its root
$dom = new DOMDocument('1.0', 'utf-8');
$root = $dom->createElement('ingredients','');
$dom->appendChild($root);

// create new ingredient and link it to root 
$ingredient = $dom->createElement('ingredient','');
$root->appendChild($ingredient);    

// create children and link them to ingredient
$q_amount = $dom->createElement('quantity_amount',"1");
$q_name = $dom->createElement('quantity_name',"spoon");
$i_name = $dom->createElement('ingredient_name',"PHP");
$ingredient->appendChild($q_amount);
$ingredient->appendChild($q_name);
$ingredient->appendChild($i_name);

echo $dom->saveXML();

确保在将表单中的用户输入插入XML之前对其进行清理。

使用HTML格式从PHP创建XML结构
