Question

林＆＃39;不完全确定我问了正确的问题，但也许如果你看到代码它可能更好地解释我试图做的事情。

因此，下面的查询会侦听上一页的帖子信息：

    if (isset($_REQUEST["water-selection"])
        && $_REQUEST["water-selection"]!="Water Selection"){

  unset($_GET['page']);
  $qs = http_build_query($_GET);
?>

帖子网址的示例如下：

[site]/listing.php?keyword="321+STREETNAME+STREETDirection+City+State&......

如果我单独执行某些操作，例如"321"，它会正确搜索321，但是，如何才能搜索"321" + "Streetname" + City + State,等...

希望这是有道理的。我基本上不能用它来搜索多个匹配。

我在想可能会将OR更改为AND，但之后如何将其他关键字分开？

Answer 1

<?php
$where = '';

if (isset($_GET['keyword']) && '' !== trim($_GET['keyword'])) {
  $terms = explode(' ', $_GET['keyword']);
  $fields = array('city', 'state', 'zipcode');
  $criteria = array();
  foreach ($terms as $term) {
    if (!$term) continue;
    $term = @mysql_real_escape_string($term);
    $c = array();
    foreach ($fields as $field) {
      $c[] = 'field_'.$field.' LIKE \'%'.$term.'%\'';
    }

    $criteria[] = implode(' OR ', $c);
  }

  if ($criteria) {
    $condition = '('.implode(")\nAND (", $criteria).')';
    if ($where) $where .= ' AND ('.$condition.')';
    else $where = $condition;
  }
}

var_dump($where);

请使用转义函数或更好的预处理语句来处理SQL注入问题。此外，此解决方案远非最佳，您应考虑限制可搜索的字段（例如，使用下拉列表）。

Answer 2

尝试使用explode()功能。您将获得一系列关键字。

$keywords = $_REQUEST["keyword"];
$arrayOfKeywords = explode('+', $keywords)

如何在一个字符串中请求多个查询？
