Question

在我的数据库中，我有3行。产品，数量和费率。

$rate = implode(",", $_POST["myrate"]);

这是费率。这意味着一行可以是＆＃34; rate1，rate2，rate3＆＃34;等等。但它与产品和数量相同。

"product1, product2, product3"
"quantity1, quantity2, quantity3"
"rate1, rate2, rate3"

如果我回应它，它将如上所述。但我想要的是：

"product1, quantity1, rate1"
"product2, quantity2, rate2"
"product3, quantity3, rate3"

这怎么可能？

https://www.sanwebe.com/2013/03/addremove-input-fields-dynamically-with-jquery 这就是我正在使用的代码。刚添加了2个字段和2行。

我的PHP代码：

<?php
    //Open a new connection to the MySQL server
    $mysqli = new mysqli('localhost','root','','invoice-generator');

    //Output any connection error
    if ($mysqli->connect_error) {
        die('Error : ('. $mysqli->connect_errno .') '. $mysqli->connect_error);
    }

    $capture_field_vals = "";
    if(isset($_POST["mytext"]) && is_array($_POST["mytext"])){
        $capture_field_vals = implode(",", $_POST["mytext"]); 
        $quantity = implode(",", $_POST["myquantity"]); 
        $rate = implode(",", $_POST["myrate"]); 
    }else{
        echo "error";
    }

    //MySqli Insert Query
    $insert_row = $mysqli->query("INSERT INTO invoice_rows (product, quantity, rate) VALUES ('$capture_field_vals', '$quantity', '$rate')");

    if($insert_row){
        echo 'Success!';
    }else{
        echo "error2";
    }
?>

Answer 1

$quantity = array("q1","q2","q3","q4");
$product = array("p1","p2","p3","p4");
$rate = array("r1","r2","r3","r4");

for ($i = 0; $i < count($quantity); $i++) {
    $new_data[] = array($quantity[$i],$product[$i],$rate[$i]);
}

在循环中获取所有这些并将值转储到一个数组中。

Answer 2

如果所有变量的数量都相同，那么

if (count($_POST["mytext"]) == count($_POST["myquantity"]) && count($_POST["myquantity"]) == count($_POST["myrate"])) {
   for ($i = 0; $i < count($_POST["mytext"]); $i++) {
    echo $_POST["mytext"][$i] . "," . $_POST["myquantity"][$i] . "," . $_POST["myrate"][$i] ."<br/>";
   }
}

Answer 3

<table>
<thead>
<tr>
<th>Product</th>
<th>Quantity</th>
<th>Rate</th>
</tr>
</thead>
<tbody>
//Lets say you have the data from your db in $results
<?php foreach($results as $result): ?>
<tr>   //loop one whole row
<td><?=$result['product']?></td>
<td><?=$result['quantity']?></td>
<td><?=$result['rate']?></td>
</tr>
<?php endforeach; ?>
</tbody>
</table>

This way you can show product,quantity and row for each id in your database table in one row...if that is what you want
