page went blank on adding 2nd array

[bsaid1_acu419164]

Hi, i have tried to reproduce cars example given in this url: http://www.i-cre8.co.uk/webassist/multiple-dynamic-dropdowns/cars.php , using DW CS5 , Apache 2.2.15 (Win32), PHP 5.2.13 , Mysql 5.1.
When i add the first array, the drop down "models" work fine. but when I add the second array for the "engine size" the browser's page went blank.
I have tried my owns tests with different tables but same results.
would please take a look to the attachement :

a blank p[age means that a php error is occuring.

add the following at line 1 to turn error reporting on:
<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>[/php]



from your source, it looks like you are using an older version of dynamic drop downs.


the error is that this function is being repeated on the page:
function WA_DD_Replace($startStr) {
$startStr = str_replace("'", "|WA|", $startStr);
$startStr = str_replace("\\", "\\\\", $startStr);
$startStr = preg_replace("/[\r\n]{1,}/", " ", $startStr);
return $startStr;
}


this is a bug that was corrected in the latest version of Dynamic Dropdowns.

Thanks for relpy
dropdowns v.2.7.0
I have added the lines as you advice to get errors displayed but page always turns blank.
I have modified the php.ini file so that display_errors = On but same result.
tested this on FF and IExplorer
any ideas?
Please help.

finally it's resolved
the error was :

Fatal error: Cannot redeclare wa_dd_replace() (previously declared in F:\UniServer5_6b\UniServer56b\www\pdrmt\cars.php:9 2) in F:\UniServer5_6b\UniServer56b\www\pdrmt\cars.php on line 144

I have deleted :
function WA_DD_Replace($startStr) {
$startStr = str_replace("'", "|WA|", $startStr);
$startStr = str_replace("\\", "\\\\", $startStr);
$startStr = preg_replace("/[\r\n]{1,}/", " ", $startStr);
return $startStr;
}

Now it's OK
very thanks for the help

glad to hear it is working.

Just to add that the latest version of Dynamic Dropdowns (2.7.5) solves this issue, so you should download it from the downloads section of your account.
