我有以下代码，将数据插入我的sql数据库。 ：
<?php
require 'database.php';
if(!empty($_GET['wid'])) { $wid = $_GET['wid']; }
elseif(!empty($_POST['wid'])) { $wid = $_POST['wid']; }
else { $wid = null; }
if ( !empty($_POST)) {
// keep track validation $
$ModelError = null;
$DescriptionError = null;
$CostError = null;
$RetailError = null;
$QuantityError = null;
// keep track post values
$Model = $_POST['model'];
$Description = $_POST['description'];
$Cost = $_POST['cost'];
$Retail = $_POST['retail'];
$Quantity = $_POST['qty'];
// validate input
$valid = true;
if (empty($Model)) {
$ModelError = 'Please enter Model';
$valid = false;
}
if (empty($Description)) {
$DescriptionError = 'Please enter Description';
$valid = false;
}
if (empty($Cost)) {
$CostError = 'Please enter Cost';
$valid = false;
}
if (empty($Retail)) {
$RetailError = 'Please enter Retail';
$valid = false;
}
if (empty($Quantity)) {
$QuantityError = 'Please enter Quantity';
$valid = false;
}
if ($valid) {
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO items (WID, model, description, cost, retail, qty) values(?, ?, ?, ?, ?, ?);";
$q = $pdo->prepare($sql);
$q->execute(array($wid,$Model, $Description, $Cost, $Retail, $Quantity));
Database::disconnect();
header("Location: index.php");
}
}
?>

此代码在更改之前完美运行。在我添加此代码之前，它一次只能在数据库中插入一行：
<div class='row'>
<div class='col-xs-12 col-sm-3 col-md-3 col-lg-3'>
<button class="btn btn-danger delete" type="button">- Delete</button>
<button class="btn btn-success addmore" type="button" id="Add">+ Add More</button>
</div>
</div>
和ajax后端：
//adds extra table rows
var i=$('table tr').length;
$(".addmore").on('click',function(){
html = '<tr>';
html += '<td><input class="case" type="checkbox"/></td>';
html += '<td><input type="text" data-type="ID" name="idNo[]" id="idNo_'+i+'" class="form-control autocomplete_txt" autocomplete="off"></td>';
html += '<td><input type="text" data-type="model" name="model[]" id="model_'+i+'" class="form-control autocomplete_txt" autocomplete="off"></td>';
html += '<td><input type="text" data-type="description" name="description[]" id="description_'+i+'" class="form-control autocomplete_txt" autocomplete="off"></td>';
html += '<td><input type="text" data-type="cost" name="cost[]" id="cost_'+i+'" class="form-control autocomplete_txt" autocomplete="off"></td>';
html += '<td><input type="text" data-type="retail" name="retail[]" id="retail_'+i+'" class="form-control autocomplete_txt" autocomplete="off"></td>';
html += '<td><input type="text" data-type="quantity" name="quantity[]" id="quantity_'+i+'" class="form-control changesNo" autocomplete="off" onkeypress="return IsNumeric(event);" ondrop="return false;" onpaste="return false;"></td>';
html += '</tr>';
$('table').append(html);
i++;
});
//to check all checkboxes
$(document).on('change','#check_all',function(){
$('input[class=case]:checkbox').prop("checked", $(this).is(':checked'));
});
//deletes the selected table rows
$(".delete").on('click', function() {
$('.case:checkbox:checked').parents("tr").remove();
$('#check_all').prop("checked", false);
calculateTotal();
});
//autocomplete script
$(document).on('focus','.autocomplete_txt',function(){
type = $(this).data('type');
if(type =='ID' )autoTypeNo=0;
if(type =='model' )autoTypeNo=1;
$(this).autocomplete({
source: function( request, response ) {
$.ajax({
url : 'ajax.php',
dataType: "json",
method: 'post',
data: {
name_startsWith: request.term,
type: type
},
success: function( data ) {
response( $.map( data, function( item ) {
var code = item.split("|");
return {
label: code[autoTypeNo],
value: code[autoTypeNo],
data : item
}
}));
}
});
},
autoFocus: true,
minLength: 0,
select: function( event, ui ) {
var names = ui.item.data.split("|");
id_arr = $(this).attr('id');
id = id_arr.split("_");
$('#idNo_'+id[1]).val(names[0]);
$('#model_'+id[1]).val(names[1]);
$('#description_'+id[1]).val(names[2]);
$('#cost_'+id[1]).val(names[3]);
$('#retail_'+id[1]).val(names[4]);
$('#quantity_'+id[1]).val(1);
$('#total_'+id[1]).val( 1*names[4] );
calculateTotal();
}
});
});
//It restrict the non-numbers
var specialKeys = new Array();
specialKeys.push(8,46); //Backspace
function IsNumeric(e) {
var keyCode = e.which ? e.which : e.keyCode;
console.log( keyCode );
var ret = ((keyCode >= 48 && keyCode <= 57) || specialKeys.indexOf(keyCode) != -1);
return ret;
}
和
<?php
require_once 'config.php';
if(!empty($_POST['type'])){
$type = $_POST['type'];
$name = $_POST['name_startsWith'];
$query = "SELECT ID, model, category, subcategory, description, cost, retail FROM products where UPPER($type) LIKE '".strtoupper($name)."%'";
$result = mysqli_query($con, $query);
$data = array();
while ($row = mysqli_fetch_assoc($result)) {
$name = $row['ID'].'|'.$row['model'].'|'.$row['description'].'|'.$row['cost'].'|'.$row['retail'];
array_push($data, $name);
}
echo json_encode($data);exit;
}
现在，我得到了代码的ajax部分的帮助，它可以正常工作（正确添加表单字段），并且POST结果正常工作（屏蔽了firefox＆＃39的Web开发人员选项卡，并且它发布了我的所有表单正确的字段数据），我遇到的唯一问题是如何一次翻译MULTIPLE提交。显然，我使用一个提交的sql代码不能与多个连续提交一起使用，并且我收到以下错误：
注意：第131行C：\ wamp \ www \ invoice \ index.php中的数组到字符串转换调用堆栈#TimeMemoryFunctionLocation 10.0012276928 {main}（）.. \ index.php：0数组＆＃34; class =＆＃34; form-control autocomplete_txt＆＃34;自动填充=＆＃34;关闭＆＃34;＆GT;
出于某些奇怪的原因：
注意：未定义的索引：第24行的C：\ wamp \ www \ invoice \ index.php中的数量
任何有关此事的帮助都会非常感激，现在已经进行了一周多的故障排除：P
答案 0 :(得分：1)
我不确定你要求的是什么。但只需循环播放数组即可：
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "INSERT INTO items (WID, model, description, cost, retail, qty) values(?, ?, ?, ?, ?, ?);";
$q = $pdo->prepare($sql);
$idx = 0;
foraech ($Model as $model_idx) {
$q->execute(array($wid,$model_idx, $Description[$idx], $Cost[$idx], $Retail[$idx], $Quantity[$idx]));
$idx++;
}
