Question

我无法提取数组以插入数据库。我的表单接受多个动态数量的输入，所以我将数据放在一个数组中，输入phonenos []和phonetypes []：

<form name="add" action="" method="POST">
<input name="name" type="text" placeholder="Name"></input><br />
    <input name="qty" type="text" placeholder="Qty"></input><br /> -->
    <input class="form-control required" name="phonenos[]" maxlength="14" type="text" placeholder="number..."><br>
    <select class="form-control" name="phonetypes[]">
        <option value="0">Choose a phone type</option>
        <option value="Main">Main</option>
        <option value="Fax">Fax</option>
        <option value="Mobile/Direct">Mobile/Direct</option>
    </select>
    <div id="addmore">
        <input type="button" value="Add More" onClick="addRow(this.form)"></input>
    </div>
    <input type="submit" value="submit" name="action"></input>
</form>

在我的PDO查询中：

..... first query insertion...

$phonenos = $_POST['phonenos'];

foreach($_POST['phonenos'] as $phoneno) {
    $phoneno;
}

$phonetypes = $_POST['phonetypes'];

foreach($_POST['phonetypes'] as $phonetype) {
    $phonetype;
}

$sql = 'INSERT INTO phone (p_id, phoneno, phonetype) values (:p_id, :phoneno, :phonetype)';
$query = $conn->prepare($sql);
$query->execute( array(
        ':p_id'=>$lastid,
        ':phoneno'=>$phoneno,
        ':phonetype'=>$phonetype
    ));

所以我在提交多个电话号码后对变量$ phoneno和$ phonetype做了var_dump，它只打印出最后一个数字和类型，而我想要提交的整个列表。如何获取所有数据，以便将其插入数据库？

Answer 1

如果你想在同一列中插入所有数字，那么我认为最好的解决方案是在插入db之前序列化它们。

$phonenos = serialize($_POST['phonenos']);
$phonetypes = serialize($_POST['phonetypes']);

$sql = 'INSERT INTO phone (p_id, phoneno, phonetype) values (:p_id, :phoneno, :phonetype)';
$query = $conn->prepare($sql);
$query->execute( array(
        ':p_id'=>$lastid,
        ':phoneno'=>$phonenos,
        ':phonetype'=>$phonetypes
    ));

Answer 2

我通过for循环找到了解决方案。

$phones = $_POST['phones'];
$phonetypes = $_POST['phonetypes'];

for($i = 0, $j = 0; $i <= $phones, $j <= $phonetypes; $i++, $j++) {
    $phone = $phones[$i];
    $phonetype = $phonetypes[$j];

    $sql = "INSERT INTO phone (p_id, phone, phonetype) values (:p_id, :phone, :phonetype)";
    $query = $conn->prepare($sql);
    $query->execute( array(
        ':p_id'=>$lastid,
        ':phone'=>$phone,
        ':phonetype'=>$phonetype
    ));
}
