Search query for texarea (with new line....) - php

Question

I have a form with some fields. Address is one of them. I used textarea tag for address.
Now the problem is, when i search something according to one address, it only works for the one line addresses. I mean if i entered a newline (Paragraph format) in my address it doesn't show the result.
All other search query working very well.Here is my codes,
Code for drop-down list of address :
<input type="hidden" name="category_address" value="address"/>
<select name='criteria_address' style="width:100px;">
<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>$data[address]</option>");
}
?>
</select>
Code of search query :
if (isset($_POST['criteria_address']))
{
$category_address = $_POST['category_address'];
$criteria_address = $_POST['criteria_address'];
$query = "SELECT * FROM lh_clients WHERE $category_address = '$criteria_address' ORDER BY clientname";
$result = mysql_query($query) or die(mysql_error());
$num_rows = mysql_num_rows($result);
while ($data = mysql_fetch_array($result)) { ?>
<tr>
<td style="vertical-align:top;"><? echo $data['clientname']; ?></td>
<td style="vertical-align:top;"><? echo $data['clienttype']; ?></td>
<td style="vertical-align:top;"><? echo nl2br($data['address']); ?></td>
<td style="vertical-align:top;"><? echo $data['contacts']; ?></td>
<td style="vertical-align:top;"><? echo $data['sensitivity']; ?></td>
<td style="vertical-align:top;"><? echo $data['acountmanager']; ?></td>
<td style="vertical-align:top;"><? echo $data['responsibleexecutive']; ?></td>
<td></td>
</tr>
<?php
}
}
I think the search query doesn't work for the newline in addresses.

Answer 1

Well...
$order = "SELECT DISTINCT address FROM lh_clients ORDER BY clientname" or die (mysql_error());
$result = mysql_query($order);
while ($data = mysql_fetch_array($result)) {
foreach (explode("\n", $data[address]) as $line) {
echo ("<option value='".htmlentities($line)."'>{$line}</option>");
}
}
Try use LIKE for search in text columns
$address = trim(html_entity_decode($criteria_address));
$query = "SELECT * FROM lh_clients WHERE $category_address like '%{$address}%' or $category_address like '{$address}%' or $category_address like '%{$address}' ORDER BY clientname";

Answer 2

You could try using the LIKE operator like so:
WHERE $category_address LIKE '{$criteria_address}%'
This will find all records starting with $criteria address.
