Question

我正在尝试编辑搜索栏，以便用户可以搜索以逗号分隔的值。它调用mySQL db。有人可以帮忙吗？我相信这一定是显而易见的，但我是新人。谢谢！

搜索页面：

<?php require_once($_SERVER['DOCUMENT_ROOT']."/includes/session.php");?>
<?php require($_SERVER['DOCUMENT_ROOT']."/includes/db_connection.php");?>
<?php require_once($_SERVER['DOCUMENT_ROOT']."/includes/functions.php");?>

<?php include("../includes/header-home.php"); ?>
<div class="container">
  <div class="col=md-12">
    <p><strong>Search:</strong></p>
   <form name="form1" method="post" action="search_results.php">
    <p><input name="search" type="text" size="40" maxlength="50"/></p>
    <p>
     <input type="checkbox" name="type[]" value="1"> Medalist</p>

<p><strong>Medal:</strong>
<select name="medal">
<option disabled selected></option>
<option value="1">Medal 1</option>
<option value="2">Medal 2</option>
<option value="3">Medal 3</option>

</select>
</p>
<p><strong>State:</strong>
<select name="state">
<option disabled selected></option>
<option value="1">AL</option>
<option value="2">AK</option>
<option value="3">AZ</option>
<option value="4">AR</option>

</select>
</p>
<p><strong>Year:</strong>
<select name="year">
<option disabled selected></option>
<option value="2014">2014</option>
<option value="2013">2013</option>
<option value="2012">2012</option>
<option value="2011">2011</optio>
</select>
</p>
<p><strong>Topic:</strong>
<select name="field">
<option disabled selected></option>
<option value="1">Field 1</option>
<option value="2">Field 2</option>
<option value="3">Field 3</option>

</select>
</p>

Answer 1

您可以执行以下操作：

$searchArray = explode(',', $_POST['search']);

然后通过该数组运行每个项目的搜索查询，追加每个查询的结果，然后显示完整列表。

Answer 2

你可以爆炸搜索然后使用这些值吗？

$search = $_POST['search'];
$myNewSearch = explode(",",$search);
$searchLen = count($myNewSearch);
for($i = 0; $i < $searchLen; $i++){
 Select * from profiles WHERE (
 first_name      LIKE '%{$myNewSearch[$i]}%'
 ... 
}

它有点长，但如果没有逗号，它会为你输入所有内容。

搜索栏能够用逗号搜索 - mySQL / php
