PHP/MySQL - ORDER by not working - php

Question

Here is my code:
<?php
if($_rate->getCode()=="matrixrate_matrixrate") {
$resource = Mage::getSingleton('core/resource');
$readConnection = $resource->getConnection('core_read');
$query = 'select * from `extensa_econt_city_office` WHERE `delivery_type`="to_office" GROUP by `city_id`';
$results = $readConnection->fetchAll($query);
?>
<center><b>Населено място:</b></center>
<select name="shipping_city" id="shipping-city-select" title="">
<option value="">Изберете град</option>
<?php
foreach($results as $row){
$CityCode = $row['city_id'];
$query1 = "select * from `extensa_econt_city` WHERE `city_id`='$CityCode' AND `type`!='с.' ORDER by office_id DESC";
$results1 = $readConnection->fetchAll($query1);
foreach($results1 as $row1){
?>
<option value="<?PHP echo $row1['city_id']; ?>"><?PHP echo $row1['type']; ?> <?PHP echo $row1['name']; ?></option>
<?php
}
}
?>
</select>
For some reason the ordering with ORDER by office_id DESC is not working.
There is no change if I change DESC to ASC or even if I remove the ORDER by statement.
Do you have any suggestion why it is not ordering the rows properly ?

Answer 1

You Missing ``(quotes) around office_id
if you still find that query is not working then print whole query using echo statement..
copy that query and paste in php-myadmin and check which sql exception you getting..

Answer 2

hi maybe you can check your sintaxis your code maybe have a little error
for this i suggest that you run your query on phpmyadmin and check if the result is correct , then is correct the result you have a debug on your code php
this a little example for you
<?php
$link=Conect();
$query="SELECT * FROM clients ORDER BY client_name ASC";
$result=mysql_query($query,$link) or die("Error: ".mysql_error());
if(mysql_num_rows($result) > 0)
{
?>
<table border="0">
<tr COLSPAN=2 BGCOLOR="#6D8FFF">
<td>ID</td>
<td>NAME</td>
<td>PHONE</td>
</tr>
<?php
while($row=mysql_fetch_array($result))
{
echo "<tr>".
"<td>".$row["id"]."</td>".
"<td>".$row["client_name"]."</td>".
"<td>".$row["phone"]."</td>".
"</tr>";
} /
}
else
{
echo "don't exist clients for list";
}
mysql_close($link);
?>
</table>
good luck and try
