[Plugin: Contact Form 7] This is how to show/hide fields with jQuery

Oh I should have added..

How do you modify the example?
To make this work for your own specific needs, you need to modify steps 2 and 3 so that the form and jQuery work together to hide the fields you want them to. You will also need to modify step 4 to get CSS styling you prefer.

I suggest doing what I did and reading about what jQuery functions mean what. There are loads of tutorials to explain jQuery functions, so get Googling.

With a little reading, you can adjust the script I wrote to to handle responses to checkboxes, radiobutton, etc.

Best of luck ??

I just wanted to say you are amazing! I’ve wanted this functionality for quite a while but only last night did a client want it. After stressing out and using some other examples that didn’t work I stumbled upon this, and I’m glad I did. It works perfectly for what I need and will help my client save a little by using this free alternative rather than some other paid options I wont mention.

I’m not a major coder, I can edit bits here and there and I know which way is up, so I’m not a total noob either, but I was wondering why the script only worked if the JS was in the /my-theme/js/1.7.1/ directory. I usually keep all the javascript files within /my-theme/js/ without another directory and I edited the code in step 5 for the header to reflect this and nothing worked. I then followed your instructions perfectly to get it working and it did! I couldn’t find any reference to only finding the script in that directory so I wondered what’s going on..

Anyway thanks again! All the posts on this have been 1-2 years old and I’m surprised this hasn’t been added to the core of the plugin yet, I’m glad you shared this.

You’re very welcome!

I found the same when I looked yesterday; lots of posts 1-2 years old with people asking how to do this, but no detailed answers with examples given. I wanted it for myself and had a free afternoon yesterday, so went digging.

As for the 1.7.1 thing, that’s just me following the filing conventions that WordPress seems to use to file scripts. I noticed it gives each a folder with the version number on it and (to be quite honest) I figured….I better do that just in case it means something ??

I’m sure it would work fine if you put it into plain old /js folder, as long as your call to it (in my step 5) looks for it there.

Anyhoo, really glad this was useful for you ??

That’s the thing though, I did just put it into the /js folder and called it in the header with:

<script type=”text/javascript” src=”<?php echo get_stylesheet_directory_uri(); ?>/js/jquery-1.7.1.min.js”></script>

But it didn’t work. I assumed it would work if I filled in the location/name in step 5 but nothing. It’s only when I filled it as you said that it did work. I just wondered if there was anything hidden away in the script that specifically asked for that file structure.

And you’re right, perhaps I should start using this structure as well, it seems to make sense!

Hrm, well I noticed a typo in my step 5 above. It should say this:

<!-- Add jquery script to support Conditional Forms-->
<script type="text/javascript" src="<?php echo get_stylesheet_directory_uri(); ?>/js/1.7.1/jquery-1.7.1.min.js"></script>
<script type="text/javascript" src="<?php echo get_stylesheet_directory_uri(); ?>/js/hidefieldsScript.js"></script>

The filename I gave for jQuery 1.7.1 was slightly borked. Here I am telling folks to “download this file here” then I give it a different name when I get to the step that needs it. Good one Bunny, great stuff….

Glad you got it working though ??

I hadn’t even noticed that before. I’m glad it’s working now though, there goes the rest of my night I’m about to code up some awesome contact forms, thanks again!

You are awesome! What more can I say?

I concur with base007. I was trying to figure out how to do this for the past few weeks (see here). Unlike many on these boards, I know virtually nothing about coding outside of general html. It took me a few days of trial and error and re-reading this thread dozens of times to get everything set right. I think I am pretty close now, but I have an additional question or two that I wonder if someone can point me in the right direction.

(1) I have a conditional field in my form that requires a five character response entry. I’ve limited the text field to 5 characters maximum, but is there a way to mandate that 5 characters be entered and not 1-4?

(2) More of a formatting issue. I have a CAPTCHA field with a brief explanation under the text entry box. All of my other text entry explanations are neatly lined up underneath the text field, while the CAPTCHA explanation is left aligned and I cannot figure out how to line it up properly.

Here is a screenshot of the form showing the two above matters; and here are the snippets of code that produced it.

Hey there – I’m glad this was helpful for you.

I don’t think I can help with the other two issues you have though sadly, as they don’t relate to showing/hiding fields with jQuery ??

(1) The first question relates to the minlength attribute, which does not exist with HTML5 or Contact Form 7.

I’m no expert, but I think normally in HTML5 you add this kind of validation into the script handling your Form (it’s easier), but in this case the AJAX script lives in the Contact Form 7 plugin itself. I suggest you raise it as a question for the CF7 writers, they may be able to help you with a work around for their plugin.

(2) Sounds like a CSS formatting issue, as opposed to a functionality issue. I suggest posting up your CSS in a separate thread for someone to take a look at and help you with.

Best of luck getting it sorted!

Hi,
this is great for some fields. But i want to hide a complete area.

Example: https://www.stoetefeld-catering.de/wordpress-catering/?page_id=132

I want to dupliacate the input area (2 new tables below the actual) with another topic. I want that the user have the possibility to show or hide the next area / all areas.

Does anybody have an idea how to resolve this issue?

Regards,
Manuel

Hi Schnappinator,

I’m afraid I don’t understand what you are describing. You can hide any area with the code I gave you, by putting the <div> in the correct location and using the correct field validation.

If you are trying to let users manually show/hide portions of your form (i.e. by clicking expand/collapse somewhere on your form), I believe you can do that with CSS. A script it not necessary.

Best of luck

I’ve also thought about hiding conditionally with jquery, but some issues come to mind:

• Hiding required fields
• Conditional email text

I’m currently creating a contact form for reservations or simple feedback. For this I have a drop-down menu from which the user has to choose a subject. If “Reservation” is chosen, I’ll fade in fields for date, time and number of persons to reserve a table for. Those are required fields. If the subject is “Feedback”, the above would be hidden and the form would not submit.

Maybe a possible solution would be to use
$('.selector').removeClass('wpcf7-validates-as-required')
but I haven’t tested this yet.

As for the email, I don’t have any ideas. Currently I have something like this:

Date: [date]
Time: [time]
Number of Persons: [persons]

I don’t want “Date”, “Time” and “Number of Persons” to be part of the message body when there is nothing beside them (speak user didn’t fill the appropriate fields)

Would be thankful if someone comes with a solution.

Well the removeClass thingy didn’t work out ??

Here’s the code I tried if someone is willing to help:

// Contact form conditional toggle
	$('#subject-menu').change(function() {
		var subject = $(this).val();
		if (subject == "Reservation" || subject == "Event") {
			$('#form_subject_toggle').show(1000);
			$('#form_attachment_toggle').hide(1000);
			//$('#form_subject_toggle').find('input').toggleClass('wpcf7-validates-as-required');
		} else {
			$('#form_subject_toggle').find('input').removeClass('wpcf7-validates-as-required');
			$('#form_subject_toggle').hide(1000);
			$('#form_attachment_toggle').show(1000);
		}
	});

This is just something to point out.

You should not have to add the jQuery 1.7.1 script to your head because in most wordpress themes the wp_head function is called. When it is called it automatically calls jQuery 1.7.1 and adds it between your <head></head> tags.

If you add it you will be calling the same script twice in the head of your theme.

No need to put the extra load on your site if you do not have to. ??

Other than that awesome tutorial. ??

I know I have to have the jQuery 1.7.1 script in the Header.php in order to hide the fields. But my issue is that all my items that are called out with Fancybox for WordPress on my site (including video, galleries, and modals with the forms) will not popup when the script is in place. Does anyone know of this issue with Fancybox and a fix for it? If I remove the jQuery 1.7.1 script from the Header.php, Fancybox works but of course that means my hidden fields are visable. I’m using Fancybox for WordPress Version 3.0.1 and WordPress Version 3.2.1.
