搜索欄能夠用逗號進行搜索-mySQL/php

Question

我在編輯我的搜索欄，以便用戶可以搜索以逗號分隔的值。它調用mySQL數據庫。誰能幫忙？我相信這一定很明顯，但我是新的。謝謝！

搜索頁面：

<?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">

Answer 1

你可以這樣做：

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

然後通過該數組運行每個項目的搜索查詢，追加每個查詢的結果，然後顯示完整列表。

Answer 2

你可以爆炸搜索，然後使用這些值？

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

它有點長，但它會讓你在沒有逗號的情況下輸入所有內容。
