PHP Session不会保存唯一值

Question

我想保存此按钮的name=""部分

<button type="submit" class="btn grey large" id="taxicompany" name="<? echo $rows['company']; ?>">select</button>

所以当我这样做时

<?php echo "".$_SESSION['POSTDATA']['taxicompany'].''; ?>

显示name=""

的值

但它不会显示？

Answer 1

为什么不给按钮一个值

<button type="submit" class="btn grey large" id="taxicompany" name="taxicompany" value="<? echo $rows['company']; ?>">select</button>

然后，当您提交表单并引用$ _POST ['taxicompany']时，您将获得值

Answer 2

试试这个：

<form method="post">
<button type="submit" class="btn grey large" id="taxicompany" name="taxicompany" value="your company name">select</button>
</form>

// PHP code
if(isset($_POST['taxicompany']))
{
    $_SESSION['POSTDATA']['taxicompany'] = $_POST['taxicompany'];
    echo $_SESSION['POSTDATA']['taxicompany']; //your company name
}
