php - 使用 Php 和 Mysql 插入数据时出错

Question

我有一个带有文件上传和用户名退出检查条件的表单。我面对的是数据没有插入 mysql 数据库。文件已成功保存在给定路径中。请帮助我解决这个问题，我已经浪费了 2 天的时间，我自己也尝试了很多。

表单.php

<table style="text-align:right">
    <form id="add" method="POST" action="action.php" enctype="multipart/form-data">
        <tr>
            <h4 class='bg-info'>

       echo "Username already exists";
    } else {
        echo"data entered done";
    }

    if (move_uploaded_file($_FILES["filep"]["tmp_name"], $folder . $_FILES["filep"]["name"])) {
        echo "images moved sus";
    } else {
        echo "not done";
    }

    echo "<p align=center>File ".$_FILES["filep"]["name"]."loaded...";

    $sql = "INSERT INTO userregistration "
        . "(email, password, name, location, mobilenumber, experience, keyskill, degree, hsc, gender, resume)"
        . "VALUES('$email', '$password', '$name', '$location', '$mobilenumber', '$experience', '$keyskill',
        '$degree', '$hsc', '$gender', '$resume')";
    mysqli_select_db($con, 'login');
    $retval = mysqli_query($con, $sql);
    if (!$retval) {
        die('Could not enter data: ' . mysql_error());
    }
    echo "Entered data successfully\n";
    echo'<a href="index.php"> insert more data </a>';
    mysqli_close($con);
}

我真正需要的是:我想将带有文件 url 的表单数据上传到数据库中，并且需要检查电子邮件 ID 或名称是否已经存在。

我只在 $sql = "insert into" 部分出错，其他部分工作正常。

提前致谢。

之前回显你的sql查询mysqli_select_db($con, '登录');并在您的 Mysql phpmyadmin 中执行它...

我猜你的查询格式有问题，单词之间的间距什么的。
