嘗試使用表單搜索表中的字符串？

的index.php

<html> 
    <head> 
     <title>Search the Database</title> 
    </head> 

    <body> 

    <form action="search.php" method="post"> 
    Search: <input type="text" name="search" /><br /> 
    <input type="submit" name="submit" value="Submit" /> 
    </form> 

    </body> 
</html

在這裏，我搜索數據庫與查詢

的search.php

<?php 
mysql_connect ("localhost", "db","pw") or die (mysql_error()); 
mysql_select_db ("stories"); //This selects the specific database you want your results to come from (as you may have more than one database). Change "test" to your database name. 

$search = $_POST['search']; //This grabs everything your user has put into the search field (which has been labelled as "search" earlier from the .HTML page). 

$sql = mysql_query("select * from stories where stories like '%$term%'"); //Assigns a variable called "$sql" to the result of your "search". And the use of LIKE allows you to only have to type in (for example if you were searching a name).. Jord instead of the full Jordan. 

while ($row = mysql_fetch_array($sql)){ //We start a "while" loop so you can output multiple results. Also we assign an array "$row" to each database table column you would like to display. Below is an example if you wanted multiple tables to be searched through and displayed if a match is found. 


    echo '<br/> Result '.$row['stories']; 

    } 

?>

我沒有得到任何錯誤，但我也沒有得到任何輸出。查詢有問題嗎？

'$ term'應該是您的查詢中的'$ search'。 – Rikesh

什麼是$ term這裏？ – Jenz

您正在將搜索字符串存儲在變量$search中，並使用未定義的變量$term進行搜索。試試這個。

$search = $_POST['search']; 
$sql = mysql_query("select * from stories where stories like '%$search%'");
