Brilliant Web-to-Lead for Salesforce

Hooks & Filters Documentation
I'm not seeing any errors, but the entry didn't get added to Salesforce!
To turn on in browser debugging, add a hidden field (enabled) named debug and set the value to 1.

To turn on debugging via email, add a hidden field (enabled) named debugEmail and set the value to you@yourdomain.com (your email address).

Also check for debug logs at SalesForce to see if a validation rule is the culprit: Administration Setup | Monitoring | Debug Logs.
I'm not receiving new submission emails
99% of the time the plugin is sendign these... and the issue is at the WordPress or server level.

The Give team has an excellent article on diagnosing and troubleshooting email issues.
What are the built in field names? Not all the fields are working when I use the Field Label in the lead edit screen?
SalesForce is inconsistent in naming built in fields, and even misreports the names of some fields (like MobilePhone, which is actually mobile) in the customize fields screen. Generating a Web to Lead form gets you the real names, but the list below should help as well.

Setting Up Web-to-Case
How do I setup a Web to Case form?
Choose Web to Case in the Form Settings (bottom of the form editor page).
Where do I find my Salesforce organization ID?
To find your Organization ID, do the following steps:

Log in to your SalesForce.com account
Go to Setup » Company Profile » Company Information
You'll find the Organization ID in the lower right hand corner of your screen

Go to Setup » Customize » Leads » Fields
If your custom field does not exist yet, create it now.
Find the API Name for your field (e.g. Custom_Field_Example__c). If it doesn't end in "__c" it's not the API name and will not work.
Add a new field to your form using the form editor on the plugin admin screen
Enter the API Name as the field name (left most box), then fill out the other fields normally (make sure to enable the field!).
Save your changes -- new submissions will now post that custom field to SalesForce.

Note: You must provide a value for your checkbox. Generally 1 is what you want (unless you're expecting something other than true/false in SalesForce). If you don't provide a value, your checkbox will never get sent with the form data (and even if it did, it won’t "check" the box at SalesForce as "empty" = unchecked).

Checkbox lists and radio buttons will be in a future update.
How do I pre-check a checkbox?
Before you do, consider if a pre-checked checkbox (opt-out) is really what you want to do.

If you insist on proceeding anyways: see the Pre-check a checkbox example in Other Notes.
How do I use the select (picklist) field?
Hint: Use the form importer!

Use it like any other field -- however you'll need to specify the options (and optional values) for each field using the options box (far right). You'll also need to use the "internal name" from Salesforce as your field name (see next FAQ).

The value box for a select list is the default value (the one selected on a fresh form).

/* Preferred format: */

// Use same data for display and value passed to SF
one
two
three

// Use different data for display and value passed to SF, require user to select something (assuming field is required)
Select One|
name1|value1
name2|value2

// Use different data for display and value passed to SF
name1|value1
name2|value2

/* Legacy Format (does not allow the use of colons in names or values): */

//Use same data for display and value passed to SF
one|two|three

//Use different data for display and value passed to SF, require user to select something (assuming field is required)
Select One: | name1:value1 | name2:value2

//Use different data for display and value passed to SF
name1:value1 | name2:value2

Some useful options lists -- you can remove any line(s) you don't want/need:

Note: If state and country aren't a valid combo, or the state doesn’t match the default country of your Salesforce install, your lead will likely be rejected -- so be careful with these!

How do I use the Date field?
Choose it from the dropdown, that's all you have to do.

If you want to customize the date format or display/functionality of the datepicker UI, you can set the options by entering a list of options in the Options box of the field editor, one per line.

Note that you must end each option with a comma, or you'll end up with a javascript error instead of a datepicker.

Note that any options you specify will override the default options.

e.g.

Default date format - Year, Month, Day
dateFormat : 'yy-mm-dd',

Month, Day, Year
dateFormat : 'mm-dd-yy',

Day, Month, Year
dateFormat : 'dd-mm-yy',

Day, Month, Year + Show the button panel

dateFormat : 'dd-mm-yy',
showButtonPanel: true,

More information about the datepicker options can be found here:

Examples: http://jqueryui.com/datepicker/
API Reference: http://api.jqueryui.com/datepicker/

Picklists in SalesForce (Web to Lead at least) are a strange beast -- you'd think you could pass the field name and SF would map it on their end... but they don't make it that easy. Instead you need to use the internal SF ID of the picklist... which looks more like: 00Nd0000007p1Ej (this is just en example, this is not the id of your field).

Edit the field and it'll be in the URL:
e.g. https://na14.salesforce.com/00Nd0000007p1Ej/...
Generate a Web to Lead form with your field included and it'll be in the HTML
e.g. TestPicklist: <select id="00Nd0000007p1Ej" name="00Nd0000007p1Ej" title="TestPicklist">

Then take the "name" you get (00Nd0000007p1Ej in this example) and enter that as the field name in your form editor. Yes, you enter this obtuse string of digits instead of the human readable field name (i.e. MyCustomField__c).
How do I use the HTML field?

Optionally enter a label (field will display full width if a label is not entered.
Enter HTML code in the options box.

Note: You cannot use the HTML box to enter a custom field, as only "known" fields are submitted to salesforce and HTML fields are not submitted (just displayed). Be careful to avoid the <form> or </form> tags in an HTML field as they will likely break your form.
How do I use a lookup field with a picklist field in the plugin?
Hint: Use the form importer!

Since it's a lookup field the value of the options has to be SalesForce's internal id, not the value you'd think it would be. Otherwise when Jane Doe gets married and becomes Jane Smith you'd break all the links to her user.

Basically, you need to generate a Web to Lead form in Salesforce and grab the option values from the HTML it generates.

e.g.

Find the lookup field. This is the bit you're looking for:
Joe Schmoe
Jane Doe
...

00Nd0000007p1Ej (just an example) is the SF internal ID for that choive. Enter that as the value in your pick list field options like this:

00Nd0000007p1Ej:Joe Schmoe|00Nd0000007p1aB:Jane Doe

How do I change the order of input fields?
Right now, the only way of ordering input fields is by changing the position numbers on the right hand side of the input fields table in the admin settings. Drag and drop re-ordering is on the roadmap.
How do I apply my own styling to the form?
Instructions for disabling or overriding the CSS are included on the plugin settings screen (see Style Settings).
What does "Use WPCF7 CSS integration" do?
This option adds the WPCF7 classes to the form fields so you get the WPCF7 CSS styles applied (if that plugin is also activated).
Is it possible to make multiple forms with this plugin?
Yes, version 2.0 introduces this feature.
Version 2.1 allows you to duplicate forms to reduce re-entering data.
Version 2.5 allows you to import Web-to-Lead forms from Salesforce.
How do I change the Lead Source that shows up in Salesforce?
You can easily change this by going into the admin panel and, under form settings, changing the Lead Source for that form.
I want to include the full URL the form is embedded on, but SF limits the lead source to 40 characters -- how would I do that?
The lead source supports using %URL% as the lead source (which will be replaced with the form embed url), but SF inexplicably limits the lead source to 40 characters.

Here's how to route around that:

/*
How to use:
1. Create a custom URL field at SalesForce (or Text field that holds more than 255 characters if you desire). A URL field makes it clickable in the lead detail view(s).
2. Replace URL_CUSTOM_FIELD_NAME below with the name of the custom field you setup in SalesForce,
it will be something like EmbedUrl__c
3. Add a hidden field to each form with the same field name (e.g. "EmbedUrl__c")
4. Profit
*/

add_filter( 'salesforce_w2l_field_value', 'salesforce_w2l_field_embedurl', 10, 3 );
function salesforce_w2l_field_embedurl( $val, $field, $form ){

// Target a specific field on all forms
if( $field == 'URL_CUSTOM_FIELD_NAME' )
$val = esc_url("http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);

return $val;

}

Can I change the submit button?
Of course you can! Go into the admin panel and, under Form Settings, change the text from the default "Submit" to whatever you'd like it to be!
Will I lose data if I upgrade to 2.0? Do I need to change anything?
Nope! The plugin will migrate your existing data to the new format. Your existing form will become Form 1 and be output by the [salesforce] shortcode).
How do I show my other forms?
Just use [salesforce form="X"] (X is the form number).
Or select a form number in the widget.
I put my campaign name in the Campaign_ID field but it's not working
The Campaign_ID field requires the Campaign ID -- the name will not work. To find the Campaign_ID, go your the campaign page and look in the URL bar for the ID:

e.g. https://salesforce.com/621U000000IJat

In this example, 621U000000IJat is the Campaign_ID -- make sure you use the ID from the campaign you want the lead attached to and not the example ID shown here.
Does the return/thanks URL have to be on my site?
No, as long as it's a valid URL it will work. However it should be an absolute URL regardless of where it is located.
e.g. http://yoursite.com/thanks/ not just /thanks/
Is there a limit to how many leads can be captured?
While the plugin has no limits, SalesForce does limit API calls per day:

The daily limit for Web-to-Lead requests is 500. If your organization exceeds its daily Web-to-Lead limit, the Default Lead Creator (specified in the Web-to-Lead setup page) receives an email containing the additional lead information.

See also: How many leads can we capture from our website?
Can I hide the admin message insisting I enter my organization id?
Yes. Be careful -- that's there to remind you that the plugin doesn't do much without one.

Add this to functions.php or a custom plugin (see other notes for more detailed instructions):

add_filter( 'salesforce_w2l_show_admin_nag_message', '__return_false', 10, 1 );
