Question

我试图获取动态生成的表的值并将它们插入到数据库中。这就是我现在所拥有的：

JS：注意所有值都有效，它们会被添加到表中。当按下按钮（而不是HTML代码）时，将调用此函数。

＆＃13;

function addRow1( price ) {
		var dish = document.getElementById( "cmbDish" );
		var amount = document.getElementById( "txtAmount" ).value;
		if(amount == "" || amount == "0"){
			amount = "1";
		}
		var table = document.getElementById( "datatable" );
		var comments = document.getElementById( 'txtComments' );
		var subt = amount * price;

		var rowCount = table.rows.length;
		var row = table.insertRow( rowCount );
		

		row.insertCell( 0 ).innerHTML = '<input name="fdish[]" style="border:none; background-color:transparent; text-align:center; width:100%" disabled value=' + dish.value + '>';
		row.insertCell( 1 ).innerHTML = '<input name="fcomment[]" style="border:solid; background-color:transparent; text-align:center; width:100%" value=' + comments.value + '>';
		row.insertCell( 2 ).innerHTML = '<input type="text" name="famount[]" style="border:solid; background-color:transparent; text-align:center; width:100%" value=' + amount + '>';
		row.insertCell( 3 ).innerHTML = '<input name="fprice[]" style="border:none; background-color:transparent; text-align:center; width:100%" disabled value= $' + price + '>';
		row.insertCell( 4 ).innerHTML = '<input name="fsubtotal[]" style="border:none; background-color:transparent; text-align:center; width:100%" disabled value= $' + subt + '>';
		row.insertCell( 5 ).innerHTML = '<input type="button" value = "Delete" onClick="Javacsript:deleteRow1(this)">';
		

	}

＆＃13;

HTML / PHP：注意结尾处的按钮是发出POST的按钮

<form id="frmOrder" name="frmOrder" method="post" action="<?php echo $_SERVER['PHP_SELF'] ?>#Order" >

<div id="data">
<h2>List:</h2>
<table id="datatable"  border="1" cellpadding="2" width="977">
    <tr>
        <td width="193"><h4 align="center">Dish</h4></td>
        <td width="300"><h4 align="center">Comments</h4></td>
        <td width="117"><h4 align="center">Amount</h4></td>
        <td width="100"><h4 align="center">Price</h4></td>
        <td width="119"><h4 align="center">SubTotal</h4></td>
        <td width="140"><h4 align="center">Actions</h4></td>
    </tr>
</table>
&nbsp;<br/>
</div>
        <ul class="actions">
            <p align="center"><input type="submit" class="button special" id="btnplaceOrder" name="btnplaceOrder" value="Place Order" /></p>
        </ul>
</form>

如何从表中获取所有值并将它们插入到数据库表中。我已经使用所有字段创建了数据库

我试过这个：

if(!empty($_POST['btnplaceOrder'])&&$_POST["btnplaceOrder"]!=""){

    foreach($_POST['fdish'] as $key => $value){
        $dish = $_POST["fdish"][$key];
        $comment = $_POST["fcomment"][$key];
        $amount = $_POST["famount"][$key];
        $price = $_POST["fprice"][$key];

        $res = $object->do_query("INSERT into table(Id_order, Id_menu, amount, price, comment) values (1', '$dish', '$amount', '$price', '$comment')");

    }     

}

但是没有工作，没有错误，所以我不知道它有什么问题

<强>解决我将属性disabled更改为readOnly。我忘了disabled属性阻止POST并且什么都不发送
