当我在Kaggle上执行KernalPCA代码以预测房价时，它会向我返回此类错误 <select id="Select_Product" name="Select_Product" class="select">
<option value=""></option>
<?php
//setting the select statement and running it
$search = "SELECT Item, idAdventureGear FROM AdventureGear order by Item";
echo $search;
$return = $con->query($search);
if (!$return) {
$message = "Whole query: " . $search;
echo $message;
die('Invalid query: ' . mysqli_error());
}
while ($row = mysqli_fetch_array($return)) {
if ($row['idAdventureGear'] == $product_id) {
echo "<option value='" . $row['idAdventureGear']."' selected='selected'>". $row['Item'] . "</option>\n";
} else {
echo "<option value='" . $row['idAdventureGear'] . "'>". $row['Item'] . "</option>\n";
}
}
?>
</select></p>
