我正在SELECT从数据库中访问images列以显示在HTML <table>中。我不确定下面的$sql = "SELECT Images" . "FROM koop";代码是否可以加载图像。

My page

Example page how it should look like 

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "woodstocks";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

$sql = "SELECT Type, Prijs, Adres, Woonopp, Grondopp, Slaapkamers, Badkamers, Bebouwing, Bouwjaar, Images, Text "
        . "FROM koop";

$htmlTabel = "Er is niks gevonden terug te vinden!";

$result = $conn->query($sql);
if ($result->num_rows > 0) {
    // output data of each row
    $htmlTabel = "<table class='table'>";
    $htmlTabel .= "<tr class='thead-dark'>";
    $htmlTabel .= "<th>Type</th>" .
            "<th>Prijs</th>" .
            "<th>Adres</th>" .
            "<th>Woonopp</th>" .
            "<th>Grondopp</th>" .
            "<th>Slaapkamers</th>" .
            "<th>Badkamers</th>" .
            "<th>Bebouwing</th>" .
            "<th>Bouwjaar</th>" .
            "<th>Images</th>" .
            "<th>Text</th>";
    $htmlTabel .= "</tr>";
    while ($row = $result->fetch_assoc()) {
        $htmlTabel .= '<tr>';
        $htmlTabel .= '<td>' . $row['Type'] . '</td>' .
                '<td>' . $row['Prijs'] . '</td>' .
                '<td>' . $row['Adres'] . '</td>' .
                '<td>' . $row['Woonopp'] . '</td>' .
                '<td>' . $row['Grondopp'] . '</td>' .
                '<td>' . $row['Slaapkamers'] . '</td>' .
                '<td>' . $row['Badkamers'] . '</td>' .
                '<td>' . $row['Bebouwing'] . '</td>' .
                '<td>' . $row['Bouwjaar'] . '</td>' .
                '<td>' . $row['Images'] . '</td>' .
                '<td>' . $row['Text'] . '</td>';
        $htmlTabel .= '</tr>';
    }
    $htmlTabel .= "</table>";
}

$conn->close();
?>

2 个答案:

答案 0 :(得分：0)

  

我不确定$ sql =“ SELECT Images”。 “ FROM koop”；我有的代码   下面将用于加载图像。

您必须继续尝试一下，看看它是否可以工作，但是如果您的数据库详细信息正确且查询正确，它应该可以工作。

如果图像放在名为Koop的表中，并且图像的url（可能）存储在同一表的Images列下，则查询SELECT Images FROM koop;应该工作。

因此，我制作了下一个示例，并上传图像并显示图像，但是我接近它了PICTURE 1 UPLOAD Picture 2 HTML 

<?php
$servername = "localhost";
$username = "root";
$password = "";
$dbname = "woodstocks";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
}

if (isset($_POST['Upload'])) {

    $target = "img/" . basename($_FILES['images']['name']);

    $image = $_FILES['images']['name'];

    $sql = "INSERT INTO huur (images) VALUES ('$images')";

    mysqli($conn, $sql);

    if (move_uploaded_file($_FILES['images']['tmp_name'], $target)) {
        $msg = "Image uploaded successfully";
    } else {
        $msg = "There was a problem uploading image";
    }
}
?>

        $sql = "SELECT images" . "FROM images";
        $result = msqli($conn, $sql);

        while ($row = mysqli_fetch_all($result)) {
            echo "<img src='img/".$row['images']."'>";
        }
