Question

我尝试将我的表单链接到php文件，但是出现错误并且未提交数据。我不明白如何解决它。帮我解决这个问题

表格代码：

        <form  target="_blank" action="details.php" method="post">
            <table>
                <tr>
                    <td>First Name:</td>
                    <td><input type="text" name="firstName" maxlength="25"></td>
                </tr>
                <tr>
                    <td>Last Name:</td>
                    <td><input type="text" name="lastName" maxlength="25"></td>
                </tr>
                <tr>
                    <td>Gender:</td>
                    <td><input type="radio" name="Gender" value="male">Male
                        <input type="radio" name="Gender" value="female"> Female
                    </td>
                </tr>
                <tr>
                    <td>Email:</td>
                    <td><input type="text" name="Email" maxlength="35"></td>
                </tr>
                <tr>
                    <td>Phone Number:</td>
                    <td><input type="text" name="phoneNumber" maxlength="20"></td>
                </tr>
                <tr>
                    <td>Ask question and provide background information</td>
                    <td><textarea name="information" rows="5" cols="20">put your question and background information here</textarea></td>
                </tr>
                <tr>
                    <td colspan="2" align="center"><input type="submit" name="submitForm" value="submit"><input type="submit" name="submitForm" value="reset"></td>
                </tr>
            </table>
        </form>

php文件代码：

<?php if($_POST['submitForm'] == 'reset' ){
            $_POST['firstName'] = "";
            $_POST['lastName'] = "";
            $_POST['Email'] = "";
            $_POST['phoneNumber'] = "";
            $_POST['Gender'] = "Male";
            }
    ?>

其余代码与表单相同，但不是文本框和广播，而是PHP编码

Answer 1

将value="submit"更改为value="reset"

 <input type="submit" name="submitForm" value="submit">

如果下面的代码不在details.php

上

<?php 
       if($_POST['submitForm'] == 'reset' ){
            $_POST['firstName'] = "";
            $_POST['lastName'] = "";
            $_POST['Email'] = "";
            $_POST['phoneNumber'] = "";
            $_POST['Gender'] = "Male";
       }
    ?>

然后还考虑从target="_blank"代码

中删除form

修改

根据您更新的问题，您在HTML中有两个提交按钮，将一个提交更改为type="reset"，并将isset功能添加到if条件

if(isset($_POST['submitForm']) && $_POST['submitForm'] == 'reset' ) <tr> <td colspan="2" align="center"><input type="submit" name="submitForm" value="submit"><input type="submit" name="submitForm" value="reset"> </td> </tr>

删除这一个<input type="submit" name="submitForm" value="submit">，它将起作用

如果您尝试重置表单，可以使用按钮类型重置而不是提交。

<button type="reset" value="Reset">Reset</button>

Answer 3

请从表单标记中删除 target =“_ blank”。

如果您想将表单数据发布到其他页面，请设置表单操作标记

<form  action="page url" action="details.php" method="post">

<input type="submit" name="submitForm" value="submit">

<?php if($_POST['submitForm'] == 'submit' ){
        $_POST['firstName'] = "";
        $_POST['lastName'] = "";
        $_POST['Email'] = "";
        $_POST['phoneNumber'] = "";
        $_POST['Gender'] = "Male";
        }
?>

                </tr>
                <tr>
                    <td>Ask question and provide background information</td>
                    <td><textarea name="information" rows="5" cols="20">put your question and background information here</textarea></td>
                </tr>
                <tr>
                    <td colspan="2" align="center"><input type="submit" name="submitForm" value="submit"><input type="submit" name="submitForm" value="reset"></td>
                </tr>
            </table>
        </form>


<?php
if(isset($_POST['submitForm']))
{
            $_POST['firstName'] = $fname;
            $_POST['lastName'] = $lname;
            $_POST['Email'] = $email;
            $_POST['phoneNumber'] = $phonenumber;
            $_POST['Gender'] = $gender;
            // your query goes here......
}

?>
