Search query with newline for textarea data - php

Question

i was using a input tag for entering the address in the form.
Input form code :
<input type="text" name="address">
and the search query for searching the addresses, worked without any problem
Search form code:
<input type="hidden" name="category_address" value="address"/>
<select name='criteria_address'">
<option selected="selected"> </option>
<?php
$order = "SELECT DISTINCT address FROM lh_clients ORDER BY clientname" or die (mysql_error());
$result = mysql_query($order);
while($data = mysql_fetch_array($result))
{
echo ("<option> $data[address] </option>");
}
?>
Search Result Display code :
if(isset($_POST['criteria_address']))
{
$category_address = $_POST['category_address'];
$criteria_address = $_POST['criteria_address'];
$query = "SELECT * FROM lh_clients WHERE $category_address LIKE '%".$criteria_address."%'";
echo "<tr><td colspan='8'>$num_rows Results Found</td></tr>";
while($data = mysql_fetch_array($result))
{
echo("<tr>
<td>$data[clientname]</td>
<td>$data[clienttype]</td>
<td>$data[address]</td>
<td>$data[contacts]</td>
<td>$data[sensitivity]</td>
<td>$data[acountmanager]</td>
<td>$data[responsibleexecutive]</td>
</tr>");
}
But now when i replacing the input tag and using tag instead of it
textarea code :
<textarea name="address"></textarea>
The Search code doesn't work. The tag works fine, it pop up data from the address column but doesn't providing any search result according to that address.
By the way, when i give input something with out entering newline it works.
If any one can understand my problem please reply.
Thanks a lot in advance.

Answer 1

if you put a newline in your searchword, you only gettings rows with that have that newline stored in the database.
1.
if an adress is stored in the database like
"street 1, 123 45 town",
and you try to search it by writing
"street 1
123 45 town"
they not going to match, you may want to replace newlines with % to allow other seperators.
2.
if you adress is stored in the database like street 1, and your search for
"street 1
"
then you may want to use trim() on the searchword to get rid of extra newlines
3.
to avoid carage return problem, you can use REPLACE
SELECT *
FROM lh_clients
WHERE
REPLACE(adress, '\r', '') LIKE CONCAT('%', REPLACE(:adress, '\r', ''), '%');
where :adress should be bind/replaced with the input variable
