[英]PHP search keyword
I have a problem. 我有个问题。 is there anyway to search a key word in my PHP program.
无论如何,有没有在我的PHP程序中搜索关键字。 Example if in the database There is a Full name Joe smith.
数据库中是否有全名Joe smith的示例。 And if i search Joe only it will not appear??
如果我仅搜索Joe,它将不会出现?? But if i search Joe Smith exact it will apear.
但是,如果我精确搜索乔·史密斯,它将会出现。 i want to see all the names that have a smith in it.
我想查看其中有史密斯的所有名称。 but its not showing it
但它没有显示
<?php
session_start();
if($_SESSION['username'])
{
//Include the connection file
include "connection.php";
$sql = "SELECT * FROM users ";
if (isset($_POST['search'])) {
$search_term = mysql_real_escape_string($_POST['search_box']);
$sql .= "WHERE fullname = '{$search_term}' ";
$sql .= " OR username = '{$search_term}' ";
$sql .= " OR address = '{$search_term}' ";
$sql .= " OR id = '{$search_term}' ";
}
$query = mysql_query($sql) or die(mysql_error());
echo '<FORM METHOD="LINK" ACTION="member.php">
<INPUT TYPE="submit" VALUE="Back">
</FORM>';
echo '<FORM METHOD="LINK" ACTION="display_data.php">
<INPUT TYPE="submit" VALUE="Refresh">
</FORM>';
}
else
{
die("You must be logged in!");
}
?>
<form name="search_form" method="POST" action="display_data.php">
Search: <input type='text' name='search_box' value='' />
<input type='submit' name='search' value='Search'>
</form>
<input type="button" onclick="printDiv('printableArea')" value="Print" />
<div id="printableArea">

you may try LIKE
instead of =
. 您可以尝试使用
LIKE
代替=
。
Example; 例;
SELECT aut_name, country FROM author WHERE aut_name LIKE 'W%';
and in your code 并在您的代码中
$sql = "SELECT * FROM users ";
if (isset($_POST['search'])) {
$search_term = mysql_real_escape_string($_POST['search_box']);
$sql .= "WHERE fullname LIKE '%{$search_term}%' ";
$sql .= " OR username LIKE '%{$search_term}%' ";
$sql .= " OR address LIKE '%{$search_term}%' ";
$sql .= " OR id LIKE '%{$search_term}%' ";
