我有一個表格,用戶輸入數據。行是動態創建的。用戶給出的值被髮送到數據庫(Oracle 11g),並根據其他值被提取並插入到表中。代碼如下:從數據庫中獲取值並在html表格中顯示,包括PHP
<!DOCTYPE HTML>
<html>
<body>
<?php
$code = $_POST['code'];
$qty = $_POST['qty'];
foreach ($_POST['code'] as $code => $c) {
//print $c . " " . $qty[$code] . "<br>";
}
$link = oci_connect('hd','hd', 'localhost/mydb');
if(!$link) {
$e = oci_error();
exit('Connection error ' . $e['message']);
}
foreach ($_POST['code'] as $code => $c)
{
$q1 = "select PROD_NAME, PROD_COST from PRODUCT where PROD_ALIAS = :bv_code";
$q1parse = oci_parse($link, $q1);
oci_bind_by_name($q1parse, ':bv_code', $c);
oci_execute($q1parse);
while($row = oci_fetch_array($q1parse))
PRINT $row['PROD_NAME'] . " " . $row['PROD_COST'] .
" " . $qty[$code] . " " .
($row['PROD_COST']*$qty[$code]) . "<br>";
}
?>
<script type = "text/javascript" >
function addRow()
{
var table = document.getElementById('order');
var row = table.insertRow(-1);
var cell1 = row.insertCell(0);
var cell2 = row.insertCell(1);
var cell3 = row.insertCell(2);
var cell4 = row.insertCell(3);
var cell5 = row.insertCell(4);
cell1.innerHTML = "<input type = 'text' name = 'code[]' /> ";
cell2.innerHTML = "";
cell3.innerHTML = "";
cell4.innerHTML = "<input type = 'text' name = 'qty[]' />";
cell5.innerHTML = "";
}
function delRow(r)
{
document.getElementById('order').deleteRow(-1);
}
</script>
<p><strong> Order Details </strong></p>
<form action = 'm3.php' method = 'POST' >
<table id = "order" border = 1 border_collapse = "collapse" >
<tr>
<th> Item Code </th>
<th> Name </th>
<th> Price </th>
<th> Quantity </th>
<th> Total </th>
</tr>
</table>
<input type = 'submit' name = 'submit' value = 'Submit' />
<input colspan = '2' type = "button" value = "Add Row" onclick = "addRow('order')" />
<input colspan = '2' type = "button" value = "Delete Row" onclick = "delRow('order')" />
</form>
</body>
</html>
用戶提供「CODE」和「Quantity」的值。 「代碼」被髮送到數據庫並獲取產品的其他值。問題是我想在同一個表中顯示提取的值。現在我在桌子外面顯示它。另外,我想在最後一欄顯示總賬單。如在,總價(價格*數量)。我怎樣才能做到這一點?
哦這是偉大的。它的工作原理,但如何做到這一點?如在總金額? –
@KaranGupta我已經更新了我的回答,以解決您的意見,即容納總金額計算。希望這會解決你的問題。 –
它沒有給出想要的結果。我得到一個錯誤「第70行的未定義變量sumTotal」,即我們聲明'sumTotal'的那一行。但是它也顯示了結果,雖然在表 –
