Question

我遇到此代码无法将值插入数据库的问题......

<html>
<head>
<title>Add Data</title>
</head>

<body>
<?php 
//including the database connection file
include("config.php");

if(isset($_POST['Submit'])) {    
$sitenumber = $_POST['sitenumber'];
$videolink = $_POST['videolink'];
$daynight = $_POST['daynight'];
$maxtents = $_POST['maxtents'];
$maxpersons = $_POST['maxpersons'];
$geography = $_POST['geography'];
$view = $_POST['view'];
$forestcover = $_POST['forestcover'];
$waterfront = $_POST['waterfront'];
$firepit = $_POST['firepit'];
$description = $_POST['description'];
$reslink = $_POST['reslink'];

// checking empty fields
if(empty($sitenumber) || empty($videolink) || empty($daynight) || empty($maxtents) || empty($maxpersons) || empty($geography) || 
empty($view) || empty($forestcover) || empty($waterfront) || empty($firepit) || empty($description) || empty($reslink)) {                
    if(empty($sitenumber)) {
        echo "<font color='red'>Site Number field is empty.</font><br/>";
    }

    if(empty($videolink)) {
        echo "<font color='red'>YouTube Link field is empty.</font><br/>";
    }

    if(empty($daynight)) {
        echo "<font color='red'>Day or Overnight field is empty.</font><br/>";
    }
    if(empty($maxtents)) {
        echo "<font color='red'>Maximum Tents field is empty.</font><br/>";
    }

    if(empty($maxpersons)) {
        echo "<font color='red'>Maximum Persons field is empty.</font><br/>";
    }

    if(empty($geography)) {
        echo "<font color='red'>Geography field is empty.</font><br/>";
    }
    if(empty($view)) {
        echo "<font color='red'>View field is empty.</font><br/>";
    }

    if(empty($forestcover)) {
        echo "<font color='red'>Forest Cover field is empty.</font><br/>";
    }

    if(empty($waterfront)) {
        echo "<font color='red'>Waterfront Access field is empty.</font><br/>";
    }
    if(empty($firepit)) {
        echo "<font color='red'>Firepit field is empty.</font><br/>";
    }

    if(empty($description)) {
        echo "<font color='red'>Description field is empty.</font><br/>";
    }

    if(empty($reslink)) {
        echo "<font color='red'>Reservation Link field is empty.</font><br/>";
    }
    //link to the previous page
    echo "<br/><a href='javascript:self.history.back();'>Go Back</a>";
} else {
    // if all the fields are filled (not empty)             
    //insert data to database
    $result = mysqli_query($mysqli, "INSERT INTO sites (sitenumber,videolink,daynight,maxtents,maxpersons,geography,view,forestcover,waterfront,firepit,description) 
    VALUES ('{$sitenumber}','{$videolink}','{$daynight}','{$maxtents}','{$maxpersons}','{$geography}','{$view}','{$forestcover}','{$waterfront}','{$firepit}','{$description}')");

    //display success message
    echo "<font color='green'>Data added successfully.";
    echo "<br/><a href='index.php'>View Result</a>";
} 
}
?>
</body>
</html>

我无法弄清楚......我确保这些值是从HTML表单页面传递的。我已经能够让删除页面正常工作了。＆＃39; mysqli_query（插入＆＃39;只是不会将值插入数据库。

Answer 1

如果 ELSE 正在运行， MYSQL连接正在运行，而不是查询。

mysqli_query($mysqli, "INSERT INTO sites(
    `sitenumber`,
    `videolink`,
    `daynight`,
    `maxtents`,
    `maxpersons`,
    `geography`,
    `VIEW`,
    `forestcover`,
    `waterfront`,
    `firepit`,
    `description`
)
VALUES(
    '$sitenumber',
    '$videolink',
    '$daynight',
    '$maxtents',
    '$maxpersons',
    '$geography',
    '$view',
    '$forestcover',
    '$waterfront',
    '$firepit',
    '$description'
)";

Answer 2

我想回答一下，由于echo mysqli_error（$ mysqli）而且我很清楚。我刚刚没有插入插入的reslink，因为我没有为它分配一个默认值，它就停在那里。只要我将它添加到查询中，就可以了。

mysqli_query（插入不工作
