Question

这是我的HTML表单：

                <div class="col1">

                  <div class="clear"></div>  
                  </form>

我为HTML表单的值指定的其他变量。

$Name = (string)$_POST["Name"];
                  $EMail = (string)$_POST["Email"];
                  $University = (string)$_POST["University"];
                  $Academic_Experience = $_POST["Content"];
                  $Photo = $_POST["Picture"];
                  $Publications = $_POST["Publications"];
                  $GPA = (float)$_POST["GPA"];
                  $VERBAL = (float)$_POST["VERBAL"];
                  $MATH = (float)$_POST["MATH"];
                  $EQUALWEIGHT = (float)$_POST["EQUALWEIGHT"];
                  $PBT = (float)$_POST["PBT"];
                  $CBT = (float)$_POST["CBT"];
                  $IBT = (float)$_POST["IBT"];
                  $IELTS = (float)$_POST["IELTS"];

但是当我尝试使用代码

将数据插入数据库时

$record = mysql_query("INSERT INTO Students (NAME, EMAIL, PHOTO, GPA, ALES_VERBAL_SCORES, ALES_MATH_SCORE, ALES_EQUALWEIGHT_SCORES, TOEFL_PBT, TOEFL_CBT, TOEFL_IBT, IELTS, UNIVERSITY, EXPERIENCE, PUBLICATIONS) VALUES ("."$Name".", "."$EMail".", "."$FileName".", $GPA, $VERBAL, $MATH, $EQUALWEIGHT, $PBT, $CBT, $IBT, $IELTS, "."$University".", "."$Academic_Experience".", "."$PublicationsFileName".")");

我的代码有问题。它不会将数据插入数据库。如果你帮助我，我会很高兴的。感谢...

Answer 1

值必须在单引号'$ Name'`

中

 "INSERT INTO Students (NAME, EMAIL, PHOTO, GPA, ALES_VERBAL_SCORES, 
ALES_MATH_SCORE,ALES_EQUALWEIGHT_SCORES,TOEFL_PBT, 
TOEFL_CBT, TOEFL_IBT, IELTS, UNIVERSITY,EXPERIENCE, PUBLICATIONS) 
        VALUES ('$Name', '$EMail', '$FileName', 
        '$GPA', '$VERBAL', '$MATH', 
        '$EQUALWEIGHT', '$PBT', '$CBT', '$IBT',
     '$IELTS', '$University', '$Academic_Experience', '$PublicationsFileName')"

Answer 2

看起来你错过了一些（很多）报价。尝试这种更易读的方法

$record = mysql_query("INSERT INTO Students (NAME, EMAIL, GPA, 
    ALES_VERBAL_SCORES, ALES_MATH_SCORE, ALES_EQUALWEIGHT_SCORES, TOEFL_PBT, TOEFL_CBT,
    TOEFL_IBT, IELTS, UNIVERSITY, EXPERIENCE) VALUES 
    ('$Name', '$EMail', $GPA, $VERBAL, $MATH, $EQUALWEIGHT, 
    $PBT, $CBT, $IBT, $IELTS, '$University', '$Academic_Experience')");

您无法使用$Photo = $_POST["Picture"];以不同方式处理文件上传。我从查询中删除了PHOTO和PUBLICATIONS。

警告： mysql_函数自PHP 5.5.0起已弃用，将来会被删除。相反，应使用MySQLi或PDO_MySQL扩展名。

警告：您的代码很容易出现SQL注入，请尝试使用Prepared语句。（至少正确地逃避字符串）

Answer 3

您没有在查询中将字符串包装在引号中。试试这个：

$record = mysql_query(
    "INSERT INTO Students (
          NAME, EMAIL, PHOTO, 
          GPA, ALES_VERBAL_SCORES, ALES_MATH_SCORE, ALES_EQUALWEIGHT_SCORES, 
          TOEFL_PBT, TOEFL_CBT, TOEFL_IBT, IELTS, 
          UNIVERSITY, EXPERIENCE, PUBLICATIONS
     ) VALUES (
          '$Name', '$EMail', '$FileName', 
          $GPA, $VERBAL, $MATH, $EQUALWEIGHT, 
          $PBT, $CBT, $IBT, $IELTS, 
          '$University', '$Academic_Experience', '$PublicationsFileName'
     )"
);

作为一个好的调试实践，总是将生成的查询打印出来，将其复制并在phpMyAdmin控制台或mysql CLI中运行，如果错误不是很明显的话。

例如，如果你这样做，你会立即看到没有用引号括起来的字符串。

希望有所帮助。
