DA SEARCH - currency

DA SEARCH - currency

Hello,
I have a search that uses Min and Max but it seems there is a problem.

I see that the default helper file uses:

//strips currency markup
function WADS_stripCurrency($currencyField) {
if (isset($currencyField) && $currencyField != "undefined" && $currencyField != "") {
if (is_numeric($currencyField)) {
return $currencyField;
}
else {
return preg_replace("/[^\d\.]/", "", $currencyField);
}
}
return "";
}



but I'm thinking there needs be a string_replace to remove commas?


For instance one of my values is 42,500.00

Searching 40000 - 50000 will not return a result. I'm thinking it's the comma. Is this true?

I added the string replace function but still a No-Go..

php:
//strips currency markup

function WADS_stripCurrency($currencyField)     {
  if (isset($currencyField) && $currencyField != "undefined" && $currencyField != "")     {
    if (is_numeric($currencyField))     {
      return $currencyField;
    }
    else {
      return preg_replace("/[^\d\.]/", "", $currencyField);
      return str_replace(",", "", $currencyField);
    }
  }
  return "";
}



echoing back the $currencyField value on the search page is not showing this present so maybe that was the wrong variable to be looking to manipulate?

Here is the search query string and results of echoing $currencyField:


SELECT tblhouseinfo.BedRooms, tblhouseinfo.BathRooms, tblhouseinfo.list_price, tblinventory.* FROM tblhouseinfo JOIN tblinventory ON tblinventory.invId = tblhouseinfo.addInfoID WHERE tblinventory.mid = 10 AND (list_price >= 24000) AND (list_price <= 45000) First Previous Next Last


Notice: Undefined variable: currencyField in E:\Websites\......\www\htdocs\results.php on line 209

I just realized that "WADS_stripCurrency" actually only works on the user submitted value that is being used as INPUT, not changing the values returned from the QUERY to the DB...

Need to change the DB values on the fly to strip the MySQL Currency formatting (commas) before the Search comparison occurs...

ok, Discard prior discussions and questions to this point as I can use MySQL function "replace()" to strip commas in the values available to the Search Comparison.

For example:

SELECT tblhouseinfo.BedRooms, tblhouseinfo.BathRooms, replace( tblhouseinfo.list_price , ',' , '') AS list_price, tblinventory.* FROM tblhouseinfo JOIN tblinventory ON tblinventory.invId = tblhouseinfo.addInfoID

returns the results shown in the attached screen shot.

But when the Search comparison is run, no results are returned:

SELECT tblhouseinfo.BedRooms, tblhouseinfo.BathRooms, replace( tblhouseinfo.list_price , ',' , '') AS list_price, tblinventory.* FROM tblhouseinfo JOIN tblinventory ON tblinventory.invId = tblhouseinfo.addInfoID WHERE tblinventory.mid = 10 AND (list_price >= 24000) AND (list_price <= 45000)

What as I missing? Greater or Equal to 24000 and Less than or Equal to 45000 should return records: 44900 and also 42500.00 Right??

you need to be using the replace function in the where clause, by using it in the select clause, you are only effecting the output data.

Keep in mind that the Data engine that executes the SQL Statement does not execute the query in the same order it is written

First it looks at the FROM statement, including the INNER JOINS, then filters the data from all of the table included using the WHERE clause, finally it looks at the select clause and returns only those columns.

this is why the where clause can act on columns that are not included in the select clause.


SELECT tblhouseinfo.BedRooms, tblhouseinfo.BathRooms, tblhouseinfo.list_price, tblinventory.* FROM tblhouseinfo JOIN tblinventory ON tblinventory.invId = tblhouseinfo.addInfoID WHERE tblinventory.mid = 10 AND (replace(list_price, ',' , '') >= 24000) AND (replace(list_price, ',' , '') <= 45000)


should give the result you are after.

Perfect! Thanks Jason...

Now how to edit the Where clause in the Search extension? Will I have to manually hack this in place?

edit line 39 and 40:

php:
$WADbSearch1->addComparison("list_price","".WADS_stripCurrency($_POST["start_price"])  ."","AND",">=",1);

  $WADbSearch1->addComparison("list_price","".WADS_stripCurrency($_POST["end_price"])  ."","AND","<=",1);




to:

php:
$WADbSearch1->addComparison("replace(list_price, ',' , ''","".WADS_stripCurrency($_POST["start_price"])  ."","AND",">=",1);

  $WADbSearch1->addComparison("replace(list_price, ',' , ''","".WADS_stripCurrency($_POST["end_price"])  ."","AND","<=",1);

Thanks Jason!!

Added a parenthesis and it worked perfectly.

php:
$WADbSearch1->addComparison("replace(list_price, ',' , '')","".WADS_stripCurrency($_POST["start_price"])  ."","AND",">=",1);

  $WADbSearch1->addComparison("replace(list_price, ',' , '')","".WADS_stripCurrency($_POST["end_price"])  ."","AND","<=",1);
