@DysanauthorMar 03.2008 — I trying to create a search script, that searches the name and gender columns contained in a database for keywords entered in a forms text box.

Why doesn't the following code work?

[CODE]<?php
$con = mysql_connect("localhost","peter","abc123");
if (!$con)
{
die(mysql_error());
}

mysql_select_db("db", $con);

$keywords = mysql_real_escape_string($_POST['keywords']);

$result = mysql_query("SELECT * FROM persons WHERE name, gender LIKE '%$keywords%'");

while($row = mysql_fetch_array($result))
{
echo $row['name'];
echo $row['gender'];
}

mysql_close($con);
?>[/CODE]

It's not valid sql. You need to individually check each column

this is valid:
<i>
</i>SELECT * FROM persons WHERE name LIKE '%$keywords%' or gender like '%$keywords%';

Success!
