Question

我遇到了一些我的编码问题。出于某种原因，我的条目不会丢失在我的数据库中。任何建议将不胜感激！这是我的代码......

<?php 
    $dbhost="localhost"; 
    $dbname="DBNAME"; 
    $dbuser="USER"; 
    $dbpasswd="PASSWORD"; // connect to the db 

    $dbcxn = mysqli_connect($dbhost, $dbuser, $dbpasswd); 
    if (!$dbcxn) { 
        die('Could not connect: ' . mysql_error()); 
    } 

    $db_selected = mysqli_select_db($dbcxn, $dbname); 
    if (!$db_selected) { 
        die ('Can\'t use dbreviews : ' . mysql_error()); 
    } 

    $query = "INSERT INTO entries ( submitterFirstName, submitterLastName, submitterPhone, submitterEmail, referredFirstName, referredLastName, referredPhone, referredEmail, referredReason)
      VALUES ('$submitterFirstName', '$submitterLastName', '$submitterPhone', '$submitterEmail', '$referredFirstName', '$referredLastName', '$referredPhone', '$referredEmail', '$referredProject')";

    $result=mysqli_query($dbcxn, $query);

Answer 1

您要检查的第一件事是将查询回显给您自己并阅读。

其次，检查表结构。确保列名称拼写正确并且表格中存在所有字段（我以前无意中忘记添加列）。

第三，根据您的配置，您可能会收到错误消息，也可能不会收到错误消息。但是，你可以手动检查。

if (!$result) {
  echo mysqli_error($dbcxn);
}

Answer 2

将查询变量更改为：

$query = "INSERT INTO entries " .
 "( submitterFirstName, submitterLastName, submitterPhone, submitterEmail, referredFirstName, " .
 " referredLastName, referredPhone, referredEmail, referredReason )" .
 " VALUES ('" .
    $submitterFirstName . "', '" .
    $submitterLastName  . "', '" .
    $submitterPhone     . "', '" .
    $submitterEmail     . "', '" .
    $referredFirstName  . "', '" .
    $referredLastName   . "', '" .
    $referredPhone      . "', '" .
    $referredEmail      . "', '" .
    $referredProject    . "')";

它应该有效。

建议使用mysqli prepare

首先应该是代码格式化，它将帮助您阅读代码，从而更容易发现错误。

$query = "

INSERT INTO 
    entries 
    (
    submitterFirstName, 
    submitterLastName, 
    submitterPhone,        
    submitterEmail, 
    referredFirstName, 
    " . 
       "referredLastName, 
    referredPhone, 
    referredEmail, 
    referredReason
    )
        " .
    " VALUES 
    (
    '$submitterFirstName', 
    '$submitterLastName', 
    '$submitterPhone', 
    '    $submitterEmail', 
    '$referredFirstName'," .
    "'$referredLastName', 
    '$referredPhone', 
    '$referredEmail',    
    '$referredProject'
    );
"

以上是您的查询字符串分成几行，有一些错误应该立即显现？格式化后，我会echo $query并查看$ query的输出。

还试着看看你是否可以不使用php（使用mysql workbench，php admin等）进行插入，然后将它与你设置为$ query的字符串值进行比较。

// less errors, please note that inside "" you can include php $vars without needing to escape.  

$query = "

INSERT INTO 
    entries 
    (
    submitterFirstName, 
    submitterLastName, 
    submitterPhone,        
    submitterEmail, 
    referredFirstName, 
    referredLastName, 
    referredPhone, 
    referredEmail, 
    referredReason
    )
 VALUES 
    (
    '$submitterFirstName', 
    '$submitterLastName', 
    '$submitterPhone', 
    '$submitterEmail', 
    '$referredFirstName',
    '$referredLastName', 
    '$referredPhone', 
    '$referredEmail',    
    '$referredProject'
    );
";
