[英]HTML Form loading displaying sql hex value via php
我正在嘗試動態加載將從sql數據庫中的行數填充的表單。 數據返回十六進制顏色,名稱和價格。 我想在表單中和POST上向用戶顯示顏色和名稱,我想發送附加到該特定顏色的價格。 我花了整整一天的時間試圖弄清楚這一點。
任何幫助將不勝感激!
編輯:(這是我到目前為止
這是我所擁有的示例: http : //hruska-schuman.com/test2/feedback_form.php
碼:
$query = "SELECT
`name`,
img,
price
FROM `gutter`";
try
{
$stmt = $db->prepare($query);
$stmt->execute();
}
catch(PDOException $ex)
{
die("Failed to run query: " . $ex->getMessage());
}
$rows = $stmt->fetchAll();
$form =
'<ol id="selectable" name="selectable">';
foreach($rows as $row):
$prices[] = htmlentities($row['price'], ENT_QUOTES, 'UTF-8');
$form .= '<li class="ui-widget-content" style="background:#'.htmlentities($row['img'], ENT_QUOTES, 'UTF-8').'">'.htmlentities($row['name'], ENT_QUOTES, 'UTF-8').' Price: '.htmlentities($row['price'], ENT_QUOTES, 'UTF-8').'</li>';
endforeach;
$form .=' </ol>';
?>

使用JQuery UI選擇表: http : //jqueryui.com/selectable/
我只是不知道如何獲取選定的索引並發布“ $ prices [selectedIndex]”
您應該對顏色元素使用自定義屬性(如data-
attribute)。
$form .= '<li class="ui-widget-content" style="background:#'.
htmlentities($row['img'], ENT_QUOTES, 'UTF-8').'"
data-price=".$row['price'].">'.
htmlentities($row['name'], ENT_QUOTES, 'UTF-8').
' Price: '.htmlentities($row['price'], ENT_QUOTES, 'UTF-8').
'</li>
因此,在您的js中,您可以執行以下操作:
$(function() {
$( "#selectable" ).selectable({
stop: function() {
var result = $( "#select-result" ).empty();
$( ".ui-selected", this ).each(function() {
var price = $( "#selectable li" ).attr('data-price');
result.append( "" + ( price ) );
// or you can set it directly to an input / hidden input
$('#price-input').val(price);
return price;
});
}
});
});
其中#price-input
可能是form
的隱藏輸入:
<input type="hidden" name="selectedPrice" />
當然,您也可以為此使用radio
輸入。
