Question

这是我的代码。我不确定为什么在输入第一个和最后一个名字之后第二个页面没有显示正确的文本..表格假设将名字和姓氏带入文本框..然后在下一页提交人员时它应验证输入了正确类型的数据，如果不是，则打印出文本，如果成功则打印出文本。

<body>
    <h2 style="text-align:center">Scholarship Form</h2>
    <form name="scholarship" action="process_Scholarship.php" method="post">
        <p>First Name:
            <input type="text" name="fName" />
        </p>
        <p>Last Name:
            <input type="text" name="lName" />
        </p>
        <p>
            <input type="reset" value="Clear Form" />&nbsp;&nbsp;
            <input type="submit" name="Submit" value="Send Form" />
    </form>

我的第二张表格

<body>
<?php
    $firstName = validateInput($_POST['fName'],"First name");
    $lastName = validateInput($_POST['lName'],"Last name");

    if ($errorCount>0)
        echo <br>"Please use the \"Back\" button to re-enter the data.<br />\n";
    else
        echo "Thank you for fi lling out the scholarship form, " . $firstName . " " . $lastName . ".";

    function displayRequired($fieldName)
    {
        echo "The field \"$fieldName\" is required.<br />n";
    }

    function validateInput($data, $fieldName)
    {
        global $errorCount;

        if (empty($data))
        {
            displayRequired($fieldName);
            ++$errorCount;
            $retval = "";
        } 
        else 
        {
            $retval = trim($data);
            $retval = stripslashes($retval);
        }

        return($retval);
    }
    $errorCount = 0;
?>
</body>

为什么不是我的PHP表单传递数据
