搜索查询数组值绑定不起作用答案

【问题标题】：Search query array value binding not working搜索查询数组值绑定不起作用
【发布时间】：2016-10-26 13:10:14
【问题描述】：

我正在处理搜索查询，但遇到了一点问题...所以正如您在下面的代码中看到的那样，我正在向数组添加值以便稍后在脚本中执行它，但它并没有真正起作用...因此，当我 var_dumped 所有这些时，它按预期返回，但 :q 没有更改为在链接中输入的值。

$query = "SELECT * FROM articles";

$columnsQuery = [];
$values       = [];

if(isset($_GET['q']) && !empty($_GET['q']))
{
$columnsQuery[] = " WHERE MATCH (title) AGAINST (':q' IN NATURAL LANGUAGE MODE)";
$values[":q"]   = $_GET['q'];
}

$fullQuery = $query . implode(" ", $columnsQuery)
   . " ORDER BY id DESC"
   . " LIMIT {$paginator->getLimitSQL()}";

$getArticles = $db->prepare($fullQuery)->execute($values);

    $query          = "SELECT * FROM articles";

    $columnsQuery   = [];
    $values         = [];

    if(isset($_GET['q']) && !empty($_GET['q']))
    {
        $columnsQuery[]     = " WHERE MATCH (title) AGAINST (':q' IN NATURAL LANGUAGE MODE)";
        $values["q"]        = $_GET['q'];           // TRY WITHOUT COLON
    }

    $fullQuery = $query . implode(" ", $columnsQuery)
        . " ORDER BY id DESC"
        . " LIMIT {$paginator->getLimitSQL()}";

    $getArticles = $db->prepare($fullQuery)->execute($values);

你不应该用冒号代替$values["q"] = $_GET['q'];

$query          = "SELECT * FROM articles";

$columnsQuery   = [];
$values         = [];

if(isset($_GET['q']) && !empty($_GET['q']))
{
    $columnsQuery[]     = " WHERE MATCH (title) AGAINST (':q' IN NATURAL LANGUAGE MODE)";
    $values["q"]        = $_GET['q'];           // TRY WITHOUT COLON
}

$fullQuery = $query . implode(" ", $columnsQuery)
    . " ORDER BY id DESC"
    . " LIMIT {$paginator->getLimitSQL()}";

$getArticles = $db->prepare($fullQuery)->execute($values);

是的，从您的答案中复制了..@Poiz。但据我所知，不应该有冒号..顺便说一句，如果你有问题我可以删除它。
没有错误，这是来自 var_dumping 查询和值 string(177) "SELECT * FROM 文章 WHERE MATCH (title) AGAINST (':q' IN NATURAL LANGUAGE MODE) ORDER BY id DESC LIMIT 1,5" 数组(1) { ["q"]=> 字符串(3) "tja" }

【解决方案3】：

$query = "SELECT * FROM articles";

$values = array();
if(!empty($_GET['q'])) {
  $query .= " WHERE MATCH (title) AGAINST (q IN NATURAL LANGUAGE MODE)";
  $db->bindParam(':q', $_GET['q']);
}

$fullQuery = $query  . " ORDER BY id DESC" . " LIMIT {$paginator->getLimitSQL()}"
$getArticles = $db->prepare($fullQuery)->execute();

所以过了一会儿我想通了，在查询中绑定时不应该使用参数，就像@Poiz 指出的那样，我也不应该在数组中使用冒号

感谢所有尝试提供帮助的人:)
