CSV export from the inbox is discussed in detail in this thread: how to export (inbox) to CSV in pro version.
In short: that feature is not present in simpleContact 2.0 but it is clear that customers want it so I will add it in a future version. The feature-set for version 2.1 is already decided, but I am considering re-arranging my roadmap beyond that to prioritise popular requests.
Editing error messages
The error messages can be modified easily, so translating them into Spanish should be no problem. The messages need to be changed in two places:
------------------------------------------
Open sc_admin/js/forms.js
There are instances of the following statements throughout the script:
* Please complete this field
* Please enter a valid email address
* Please select an option
Perform a find/replace for each of these messages with your chosen messages.
------------------------------------------
Open sc_admin/include/contact.php
There are instances of the following statements throughout the script:
* Please complete this field
* Please enter a valid email address
* Please select an option
Perform a find/replace for each of these messages with your chosen messages.
There is one other statement that is a little more complex to change. Towards the end of line 36 you will find the following:
"Please make this ".$max." characters or less"
$max is a PHP variable, which stores the maximum character length for a field being validated. You can change the message inside the quotemarks around this variable.
These are all the code changes you need to make to translate your error messages.
------------------------------------------
Changing "Select" in menus
My PHP is better than my Spanish, but I'll try!
Open sc_admin/js/forms.js
Change part of line 30 to say (where I am replacing Select with Elija):
if($(this).val() == "Elija") {
------------------------------------------
Open sc_admin/include/contact.php
Change part of line 18 to say:
if ($posted[$name] != "Elija"
Change part of line 48 to say:
<option value=\"Elija\">Elija</option>
Change part of line 149 to say:
$posted["title"] != "Elija"
Change part of line 217 to say:
$posted[$name] != "Elija"
Please give this a try and post back if everything was OK.
I will look into making this process easier in a future version.
