Php 通过不在postgresql中工作来订购

这不起作用，我因为某种原因从param的订单中得到一个错误

if($selected_radio == 'city')
{
    $query = "SELECT name FROM City WHERE name LIKE $1 LIMIT $2 OFFSET $3 ORDER BY name ASC";
    $result = pg_prepare($conn, "findCity", $query);
    $result = pg_execute($conn, "findCity", array($text, $limit, $offset));

    while($row = pg_fetch_assoc($result))
    {
        echo "<tr>";
        echo "<td>" . $i . "</td>";
        echo "<td>" . $row['name'] . "</td>";
        echo "</tr>";
        $i += 1;
    }
}

if（$selected\u radio==“city”）
{
$query=“从名称如$1 LIMIT$2 OFFSET$3 ORDER BY name ASC的城市选择名称”；
$result=pg_prepare（$conn，“findCity”，$query）；
$result=pg_execute（$conn，“findCity”，数组（$text，$limit，$offset））；
while（$row=pg_fetch_assoc（$result））
{
回声“；
回音“$i”；
回显“$row['name']”；
回声“；
$i+=1；
}
}

很抱歉，我对这个网站相当陌生，不知道如何正确地发布代码：/

您的条款在-ORDER BY goes before LIMIT and OFFSET中

从文档中：

SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
     * | expression [ AS output_name ] [, ...]
     [ FROM from_item [, ...] ]
     [ WHERE condition ]
     [ GROUP BY expression [, ...] ]
     [ HAVING condition [, ...] ]
     [ { UNION | INTERSECT | EXCEPT } [ ALL ] select ]
     [ ORDER BY expression [ ASC | DESC | USING operator ] [, ...] ]
     [ LIMIT { count | ALL } ]
     [ OFFSET start ]
     [ FOR { UPDATE | SHARE } [ OF table_name [, ...] ] [ NOWAIT ] [...] ]

你的条款在限制和抵消之前按顺序排列

从文档中：

SELECT [ ALL | DISTINCT [ ON ( expression [, ...] ) ] ]
     * | expression [ AS output_name ] [, ...]
     [ FROM from_item [, ...] ]
     [ WHERE condition ]
     [ GROUP BY expression [, ...] ]
     [ HAVING condition [, ...] ]
     [ { UNION | INTERSECT | EXCEPT } [ ALL ] select ]
     [ ORDER BY expression [ ASC | DESC | USING operator ] [, ...] ]
     [ LIMIT { count | ALL } ]
     [ OFFSET start ]
     [ FOR { UPDATE | SHARE } [ OF table_name [, ...] ] [ NOWAIT ] [...] ]

你能包含准确的错误消息吗？要格式化代码，请将其缩进4个空格，或者选择它，然后单击

{}

按钮。出于某种原因，我没有收到错误消息？@JoshValdivieso你应该这样做，所以你也需要对此进行调查。失败的语句报告错误消息非常重要，这样你就可以对它们采取行动。你能包含准确的错误消息吗？要格式化代码，请将其缩进4个空格，或者选择它，然后单击
