I have a form container with a regular text input element.
Is there a way to populate the data value of the input element?
I'd like to add a PHP statement to the value attribute to display a pre-fetched value from a script.
eg:
value="<?php print $v ?>"

Hi Geoff,
Yes you can use the method you posted but you have to make sure your server is setup to parse php inside html.

Except there does not appear to be anywhere to set the 'value' of the element in the Design panel.
Unless I am missing something?

No, you need to write your own scripts either php or JQuery. Another option is to set it after export.

The way that the WFB exported code works on the server is to read the html file containing the form into a variable (using file_get_contents). It is then "echoed" onto the page. Therefore, if you want to execute php within the form itself (such as to fill in value=""), you cannot use the WFB exported code snippet on your page.

Instead, you will need to export from WFB and alter the exported form. You then need to use the form code itself. You can still have it POST to the WFB processor, but you cannot use the code snippet provided by WFB at the time of export to display on the page. You have to manually put the form on your page.

I'm not using WFB at all. I build the forms using RSD (form container and elements) and then write a php script to handle it on submit (the action).
To display contents in the value field requires some editing after export from RSD to add the appropriate data population (using php from previously read values) to each form field value attribute. It works, but is messy because post-export editing is then required.
If the export included the ability to put something into 'value' then I could put the php block there and not have to edit later. Example <input value="<?php print $x ?>" ... />

However with the appropriate .htaccess file in place for the site the <?php /> contents in the .html file are evaluated through the php module in apache before being sent to the client.
