[Plugin: Contact Form 7] Adding class to form tag

Try editing this file and adding your class here. This will get overwritten next time you update the plugin, so you may want to save it as a snippet somewhere:
contact-form-7/includes/classes.php
The part that adds the existing form class:

/* Generating Form HTML */

	function form_html() {
		$form = '<div class="wpcf7" id="' . $this->unit_tag . '">';

Thank you for the quick support.

I tried to change the class from the snippet you provided. I also tried to change the variable further down pertaining to class. However neither of these changes worked. I looked at the page source code and it shows the class in the right spot but it seems something is overriding the class I am adding.

<p><div class="wpcf7" id="wpcf7-f60-p4-o1"><form action="/contact/#wpcf7-f60-p4-o1" method="post" class="box style">
<div style="display: none;">
<input type="hidden" name="_wpcf7" value="60" />
<input type="hidden" name="_wpcf7_version" value="3.1.1" />
<input type="hidden" name="_wpcf7_unit_tag" value="wpcf7-f60-p4-o1" />
<input type="hidden" name="_wpnonce" value="71ccf26a68" />
</div>

Can you post a link to your site?

This is just a development site -> https://www.portalbernicomputers.info/contact/

I’m not seeing the classes you created in any of your style sheets. FYI, box and style, with a space between are two separate classes. If you want it to be one class you need a dash in there like this: box-style. But I didn’t see that class either.

Thank you again for your time. The themes typography example page uses the following code to output the demo form with styling.

<form action="#" class="box style">

It seems to work without the use of contact form 7.

I may just code the form if I cannot figure it out.

hello,

A bit late may be but I think you are having the issue because the filter hook is changing the class value before sending it to the browser.
I wanted to change the class as well for the form tag and got the same issue.
But if you change the line that calls the filter in contact-form-7/include/classes.php like this:

`$class = apply_filters( ‘wpcf7_form_class_attr’, ‘class-you-want’ );

This modification did the trick for me…
Hope this help

Thanks,

viraks hint also worked for me!
