Subdomain as hidden field

  • Hi,

    I am trying this plugin out, and have one specific need…

    IN SHORT: –
    Basically in a nutshell. I want to invite members via unique url containing userid as subdomain value (that a long story as to why i am doing it this way, but its for tracking marketing campaigns and source of leads) upon registration the users information is stored in the db

    DETAILS: –
    The plugin will be used to register members that are sent a very unique registration link as in the following example:

    username123.mydomain.com/registration/

    upon a user arriving at this url (the registration page)

    the form has a custom hidden field called “usersubid”

    the usersubid = subdomain = username123 in this example

    the user is unaware of the hidden field and proceeds to fill in the registration form.

    upon submission the user is redirected to the thank-you page

    this all works fine with the following exception

    when reviewing the user record in the admin area. the field named “usersubid” comes back as mydomain.com rather than “username123” which is the sub part.

    I have modified the FormElement.class.php file to accommodate this functionality..

    by checking for the subdomain and then if else statement to populate the hidden field with the subdomain value. but does not work.

    However on the registration page view source. I can see that the registration page has the hidden value of “username123” for the field “usersubid”

    So im not quite sure why its not working.

    The other thing i noticed was that the form action is to self which may be causing the problem.

    I’ve even tried setting a cookie on pageload and giving the cookie value as the subdomain and then calling it in the FormElement.class.php file, but that also did not work…

    I’m not a developer, but can usually work my way around php… but at this point after spending over 4 days of trying all sorts of options.. i’m no where near a fix.

    Hence this post.

    Any help or solution to this would be appreciated.. preferably with sample code to change and direction as to which file to change

    It’s risky to edit the plugin files for several reasons. I don’t support it because I have built several ways for people to customize the functionality of the plugin. Everything you want to do there could probably be done in a custom template, and it won’t get erased when you update the plugin.

    Best way to get help with something like this is to describe what you want to happen…then some better solutions could be proposed.

    Hi,

    Thanks for replying… so soon..

    Infact I finally solved it with a small mod to formelement.class.ph

    I agree with you on the risk…

    How do i create a custom template… to display my form with my mods

    All i want to achieve is to capture the subdomain part of the url and insert it into the participants record.. just as one would insert any other custom field data.

    The only difference is that when the field that is supposed to capture the subdomain is rendered. I want it to be hidden with the value prefilled as a result of a function that extracts the subdomain from the wordpress function file.

    At this time my solution has been as follows:

    created a custom function in function.php of theme to extract subdomain part

    modified the FormElement.class.php file at line 775 as follows to call the function to get subdomain and populate the field value where field name is subdomain:

    if ( $this->name == 'subdomain' ) {
    return '<input type="' . $type . '" name="' . $this->name . ( $group ? '[]' : '' ) . '"' . $size . ( false !== $select ? $this->_set_selected( $value, $this->value, $select ) : '' ) . ' ' . $this->_attributes() . '  value="'. my_subdomain() .'" />';
    } else {
    return '<input type="' . $type . '" name="' . $this->name . ( $group ? '[]' : '' ) . '"' . $size . ( false !== $select ? $this->_set_selected( $value, $this->value, $select ) : '' ) . ' ' . $this->_attributes() . '  value="' . $value . '" />';
    }

    then tested by loading the registration page at the subdomain in question…

    and voila… it all works.. after nearly 4 days of frustration..

    if i can achieve the above via a custom template then that would be ideal…

    Appreciate your feedback and hope this post helps others with a similar requirement.

    Thanks

    Mike,

    I’m not sure I completely understand what you need, but its fairly easy to replace or modify the value of a field in a template. You would do something similar to what you did in the FormElement class…in the template, something like this after the line that has “$this->the_field()”

    <?php if ($this->field->name == 'subdomain') $this->field->value = my_subdomain(); ?>
