Question

我一直在研究以下脚本

$servername = "localhost";
$username = "blah";
$password = "blah";
$dbname = "test";


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


echo "<form id='post' action='' method='POST'>";
echo "<br />";
echo "<br />";
echo "<input type ='text' value = '' name = 'filepath'/>";
echo "<input type='submit' name='submit_form_1' value='Submit URL' id='submit';'/>";
echo "<br />";
echo "<br />";
echo "</form>";

if(isset($_POST['submit_form_1'])){
     if(empty($_POST['filepath'])) // If the checkbox array called selection is empty
    {
        echo "<p>Please enter a URL that leads to your XML</p>";
    } 
    else // If the selection array is not empty we then need to check whether ID has been selected
    {
    $test = $_POST['filepath'];
    print ($test);
    echo "<br />";

    // WE ONLY CONTINUE IF SOME TEXT WAS WRITTEN



// Testing - Get the data from a stored XML file using Simple XML
if (file_exists($test)){ // Check that the file exists
$getxml = simplexml_load_file($test) or die("Error, unfortunately there was an issue");
echo "The stuff from the XML File <br/>";

// Loop through the children within the XML file
foreach($getxml->children() as $element){

    $ID = $element->id; echo $ID;
    $area = $element->area; echo $area;
    $country = $element->country; echo $country;
    $city = $element->city; echo $city;
    $town = $element->town; echo $town;
    $postcode = $element->postcode; echo $postcode;
    $lotarea = $element->lot_area; echo $lotarea;
    $price = $element->price; echo $price;
    $bedrooms = $element->bedrooms; echo $bedrooms;
    $bathrooms = $element->bathrooms; echo $bathrooms;
    $summary = $element->summary; echo $summary;
    $latitude = $element->latitude; echo $latitude;
    $longlitude = $element->longlitude; echo $longlitude;
    $street = $element->street; echo $street;
    $streetno = $element->streetno; echo $streetno;
    $name = $element->name; echo $name;
    $image = $element->image; echo $image;


    $sql = "INSERT INTO importtest (id, area, country, city, town, postcode, 
        lotarea, price, bedrooms, bathrooms, summary, latitude, longlitude, 
        street, streetno, type, image) 
        VALUES($ID, $area, $country, $city, $town, $postcode, $lotarea, $price, 
        $bedrooms, $bathrooms, $summary, $latitude, $longlitude, $street, $streetno, $name, $image)";


if ($conn->query($sql) === TRUE) {
    echo "New record created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

}



// Insert the data we gathered from the XML file into our database
// PARAMETERIZE THIS AT SOME POINT!


$conn->close();

} else{
    echo "Unfortunately the path you entered: " . $test . " did not return a file";
}


}
}

上面的代码使用SimpleXML从用户指定的源加载XML文件。然后它获取chld节点中的所有数据并将它们设置为变量。

此时我试图在每次循环'循环'时执行一个insert语句但是我得到一个错误消息而不是插入的数据。

我的问题是我的理论是做这种事情是可行的，为什么我的INSERT语句没有按预期运行？

此外，返回的错误表示“（我试图插入的值）

附近的错误

基本上我正在尝试将一些XML数据导入我的数据库。

我认为问题在于您尝试插入的内部值。

尝试更改您的代码：

 $sql = "INSERT INTO importtest (id, area, country, city, town, postcode, 
        lotarea, price, bedrooms, bathrooms, summary, latitude, longlitude, 
        street, streetno, type, image) 
        VALUES($ID, $area, $country, $city, $town, $postcode, $lotarea, $price, 
        $bedrooms, $bathrooms, $summary, $latitude, $longlitude, $street, $streetno, $name, $image)";


if ($conn->query($sql) === TRUE) {

这种：

$stmt = $mysqli->prepare("INSERT INTO importtest (id, area, country, city, town, postcode, 
        lotarea, price, bedrooms, bathrooms, summary, latitude, longlitude, 
        street, streetno, type, image) 
        VALUES(?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?, ?)");
$stmt->bind_param('issssssiiisssssss', $ID, $area, $country, $city, $town, $postcode, $lotarea, $price,  $bedrooms, $bathrooms, $summary, $latitude, $longlitude, $street, $streetno, $name, $image);

if ($conn->execute() === TRUE) {

您必须根据表结构类型http://php.net/manual/en/mysqli-stmt.bind-param.php设置bind_param的第一个参数：

i   corresponding variable has type integer
d   corresponding variable has type double
s   corresponding variable has type string
b   corresponding variable is a blob and will be sent in packets
