how to store the query in the db and execute it at a certain time php/mysql

Hi

check this http://www.esvon.com/pg/products/p_classifieds/mod_notify/

It would have 2 multiple select boxes to select 1 or more cities and 1 or more property types, user would type first name, last name and his/her email in and subscribe.
Can you please help me i'm confused - how to get that criteria from boxes, get it compared to the data in the db , how to store that query and get it sent every day around midnight.

Any help would be appreciated
Grazias

I think that's someone else's site that he wants to emulate.

Add each multiple select box like this:

<select name="city[]" multiple="multiple">
<option value="london">London</option>
<option value="newyork">New York</option>
<option value="paris">Paris</option>
</select>

<select name="propertytype[]" multiple="multiple">
<option value="flat">Flat</option>
<option value="studio">Studio</option>
<option value="house">House</option>
</select>

then normal text input boxes for the other properties:

<input type="text" name="firstname" />
<input type="text" name="lastname" />
<input type="text" name="email" />

Storing this in a database with appropriate columns:

$query = "INSERT INTO notifications SET
firstname = '{$_REQUEST['firstname']}',
lastname = '{$_REQUEST['lastname']}',
email = '{$_REQUEST['email']}',
cities = '".implode(',', $_REQUEST['city']})."',
propertytypes = '".implode(',', $_REQUEST['propertytype']})."'";
mysql_query($query);

In a script run from a cron job, look for matching ads for each registered person:

$query = "SELECT * FROM notifications";
$result = mysql_query($query);
while ($data = mysql_fetch_array($result)) {
$query = "SELECT * FROM ads WHERE city IN({$data['cities']}) AND propertytype IN({$data['propertytypes']})";
$properties = mysql_query($query);
if (mysql_num_rows($properties) > 0) {
$details = '';
while ($property = mysql_fetch_array($properties)) {
$details .= "{$property['id'} {$property['name']} {$property['description']} {$property['price']}\n";
}
$mail = new PHPMailer;
$mail->AddAddress($data['email'], "{$data['firstname']} {$data['lastname']}");
$mail->From = 'notifications@mypropertystore.com';
$mail->Subject = "Matching properties found";
$mail->Body = "$details";
$mail->send();
}
}

That should cover the basics. I've just written this off the top of my head, so it's not tested or anything. You need to look up how to set up a cron job (plenty of examples in EE), and you need to set up the database appropriately and connect to it. Some error checking and validation would be a good idea (using $_REQUEST elements directly in SQL is not a good habit). It's using PHPMailer, which you'll need to download from here: http://phpmailer.sourceforge.net/

Hope that gets you going in the right direction.

Thanks a bunch..this was really great.
.i have small prob with this line
$query = "SELECT * FROM ads WHERE city IN({$data['cities']}) AND propertytype IN({$data['propertytypes']})";

this is how it looks in mine code

$q1 = "SELECT * FROM re2_notifications";
$p1 = mysql_query($q1) or die(mysql_error());
while($a1 = mysql_fetch_array($p1))
{
$q2 = "SELECT * FROM re2_listings WHERE city IN('$a1[sub_cities]') AND PropertyType IN('$a1[sub_types]')";
$properties = mysql_query($q2) or die(mysql_error());
$lrows = mysql_num_rows($properties);
if ($lrows > 0) {
$details = '';
while($property = mysql_fetch_array($properties)) {
$details .= "$property[ListingID] $property[Price]\n";
}

echo "$a1[sub_email], $a1[first_name] $a1[last_name]";
echo "$details";
}
}

It works only when there is a single city or single property type - with multiple - nope
This is how the table looks like...
 sub_ID  first_name  last_name  sub_email                      sub_cities                  sub_types  
  5           John     Wayne2   contact@mine-it.com          TORONTO                     Residential  
 4           John     Wayne1   john@mine-it.com     BRAMPTON,TORONTO             Residential  

is there some other way to query it or it has to be using IN, or if i missed some quotes (putting {} doesn't change anything)??
Thank you

OK i realized that cities have to have qoutes in order to get things working
'BRAMPTON', 'TORONTO'
i'm struggling to get them inserted into DB in that format now..
this is the insertions part
            $query = "INSERT INTO re2_notifications SET
      first_name = '$_POST[f_name]',
      last_name = '$_POST[l_name]',
      sub_email = '$_POST[semail]',
      sub_cities = '".implode(',', $_POST[s_city])."',
      sub_types = '".implode(',', $_POST[s_pt])."'";
    mysql_query($query);

Glad it's working. One small thing - you must quote indices of associative arrays, otherwise you'll find your error log filling up with warnings. Instead of saying this:

$_POST[f_name]

say this:

$_POST['f_name']

this can occasionally cause conflicts with quoting within SQL strings, so use {} syntax to remove ambiguity:

          $query = "INSERT INTO re2_notifications SET
     first_name = '{$_POST['f_name']}',
     last_name = '{$_POST['l_name']}',
     sub_email = '{$_POST['semail']}',
     sub_cities = '".implode(',', $_POST['s_city'])."',
     sub_types = '".implode(',', $_POST['s_pt'])."'";
