这里我有一个搜索表单和PHP搜索代码，我似乎无法解决问题。我遇到的问题是我有一个For Sale Page和一个For Rent Page，当我使用搜索表单时，它会显示属性，但它会显示For Sale Page和For Rent Page的所有属性。 如果我选择For Sale选项，那么它需要显示For Sale的所有属性，而For Rent也是如此。

我仍然是整个PHP和MySQL的新手，所以请帮助我。
这里我有搜索的PHP编码，问题就在这里，我只是不知道：
<?php
include 'database.php';
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql = "SELECT * FROM properties INNER JOIN images ON images.propertyid = properties.propertyid WHERE Status ='For Sale' OR Status = 'For Rent' GROUP BY images.propertyid";
foreach ($pdo->query($sql) as $row) {
$propertyid = $row['PropertyId'];
$pdo = Database::connect();
$pdo->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);
$sql1 = "SELECT * FROM images where PropertyId = ?";
$q1 = $pdo->prepare($sql1);
$q1->execute(array($propertyid));

答案 0 :(得分：0)
你可以像这样使用LEFT JOIN：
SELECT * FROM PROPERTIES as Prop
LEFT JOIN Images as Img
ON Img.PropertyId = Prop.PropertyId
WHERE **** Your condition ****
ORDER BY ** (DESC or ASC)
