php数组表输出
我几乎完成了这项工作，但我有以下内容：
<table border="1" cellpadding="2">
<thead>
<tr>
<th>Item Code</th>
<th>Description </th>
<th>Qty </th>
<th>Price </th>
<th>Total </th>
</tr>
</thead>
<?php
$i = 1; // Count to tell you want row we are looping through… not needed just to help $grandTotal = 0;
if (!empty($_POST)) {
// Dump POST values in array to see what the values look like
// You don't need this. It's just to see if we have more than one row in the posted
// data from the form.
echo print_r($_POST);
// Loop through each line on invoice and do something with it... i.e. Insert into database.
foreach($_POST['itemCode'] as $row => $item) {
echo '<tbody>';
echo'<tr>';
echo '<td>' . $_POST['itemCode'] . "" . "</td>";
echo '<td>' . $_POST['itemDesc'] . "" . "</td>";
echo '<td>' . $_POST['itemQty'] . "" . "</td>";
echo '<td>' . $_POST['itemPrice'] . "" . "</td>";
echo '<td>' . $_POST['itemLineTotal'] . "" . "</td>";
echo'<tr>';
echo'</tbody>';
}
}
?>
</table>
<?php
$grandTotal .= $_POST['itemLineTotal'];
echo 'Order Total: ' . $grandTotal;
?>
但是这会输出以下内容：
这是我的javascript：
$(document).ready(function () {
// We are overriding the autocomplete UI menu styles to create our own.
// You can add information from the returned json array as needed
// Just be sure that your array contains the correct value when returned
// You'll want to modify the data/item-data.php file for the returned values
$.ui.autocomplete.prototype._renderItem = function (ul, item) {
return $("<li></li>")
.data("item.autocomplete", item)
// This is the autocomplete list that is generated
.append("<a class='additionalInfo'>" + item.jItemCode + " - " + item.jItemDesc/* + " " +
// This is the hover box that is generated when you hover over an item in the list
"<span class='additionalInfoColor'>" +
"<div><h4>Item Information</h4></div>" +
"<div><strong>Item Ccsacsacsacsascaode:</strong> " + item.jItemCode + "</div>" +
"<div><strong>Qty on Hand:</strong> " + item.jQtyOnHand + "</div>" +

.appendTo(ul);
};

// onbeforeload method
$('#itemCode').focus(function () {
window.onbeforeunload = function () {
return "You haven't saved your data. Are you sure you want to leave this page without saving first?";
};
});
// Update invoice total when item Qty or Price inputs have been updated

显然，它没有从表的数组中获取正确的信息，但是在顶部输出正确的值？请帮忙。

由于每个$ _POST项都是一个数组，因此循环并拉出各个元素：
echo '<tbody>';
for ($i = 0; $i < count($_POST['itemCode']); $i++) {
echo '<tr>';
echo '<td>' . htmlspecialchars($_POST['itemCode'][$i]) . "</td>";
echo '<td>' . htmlspecialchars($_POST['itemDesc'][$i]) . "</td>";
echo '<td>' . htmlspecialchars($_POST['itemQty'][$i]) . "</td>";
echo '<td>' . htmlspecialchars($_POST['itemPrice'][$i]) . "</td>";
echo '<td>' . htmlspecialchars($_POST['itemLineTotal'][$i]) . "</td>";
echo '</tr>';
}
echo '</tbody>';
P.S。在回显用户数据时使用htmlspecialchars以防止XSS并防止文本中的任何<字符吃掉文档。

您正在使用一组值，您已将其作为键值对进行迭代。这里$ row将是数组的关键，即数组的索引
所以试试这个
foreach($_POST['itemCode'] as $row => $item) {
echo'<tr>';
echo '<td>' . $_POST['itemCode'][$row] . "" . "</td>";
echo '<td>' . $_POST['itemDesc'][$row] . "" . "</td>";
echo '<td>' . $_POST['itemQty'][$row] . "" . "</td>";
echo '<td>' . $_POST['itemPrice'][$row] . "" . "</td>";
echo '<td>' . $_POST['itemLineTotal'][$row] . "" . "</td>";
echo'<tr>';
}

我认为这正是你所追求的。大约一个小时前刚刚为我正在进行的项目做了这件事。
function hash2table($data, $show_row_numbers = true) {
$return = false;
if($data) {
$keys = array_keys($data[0]);
$keys = array_merge(array(""), $keys);
$return = "<table>";
$return .= "<thead>";
$return .= "<tr>";
foreach($keys as $key => $value) {
$return .= "<th>{$value}</th>";
}
$return .= "<tr>";
$return .= "</thead>";
$return .= "<tbody>";
foreach($data as $row_key => $row) {
$return .= "<tr>";
if($show_row_numbers) $return .= "<th>{$row_key}</th>";
foreach($row as $key => $value) {
$return .= "<td>{$value}</td>";
}
$return .= "</tr>";
}
$return .= "</tbody>";
$return .= "</table>";
return $return;
}
}
