Question

因此，我希望用户能够通过关键字或ID号进行搜索。例如，如果他们现在搜索“ test”，它将提取所有带有test的条目，这是我希望它对搜索的关键字部分执行的操作。但是，我还希望用户能够搜索我特定的特定ID＃并仅提取该特定条目。我不确定该怎么做。我尝试执行某种OR语句，但未提取任何条目。

搜索框形式

        <div class ="search" id="browse">
                <p> Find your appointment below or search by keyword</p>

                <form id="" class="searchbar" action="searchAppt.php" method="get">
                    <input type="text" name="terms" size="40" class = "sbar" placeholder="Search by issue keyword or ID" oninput="validity.valid||(value='');"
                           onblur="if (this.value == '') {
                                       this.value = 'Enter keyword or ID';
                                   }"
                           onfocus="if (this.value == 'Enter keyword or ID') {
                                       this.value = '';
                                   }"/>&nbsp;&nbsp;
                    <button type="submit" class = "btn">Search</button>

也许可以明确地对术语进行分组：

  $sql = "SELECT * FROM appointments WHERE email = '" . S_SESSION['email'] . "'";
  $exprs = array();

  foreach ($terms as $term) {
      $exprs[] = "(issue LIKE '%$term%' OR id LIKE '%$term%')";
  }

  if (!empty($exprs)) {
      $sql .= ' AND (' . join(' OR ', $exprs) . ')';
  }

在这种情况下，结果将包含与任何术语匹配的记录。

注意：最好使用laravel / PDO / mysqli之类的DB API简化查询的构建并正确地转义值。

如何根据搜索选择特定术语？
