Add markup to single field

Is there a method to add markup to a single input field when building a form?

At present I'd customise the forms markup:

$form = $modules->get("InputfieldForm");

$form->setMarkup([
    'item_content' => "{out}<span class='custom-span'></span>",
    ....
]);

Which works but adds the custom span to every inputFieldWrapper. Adjusting setMarkup on an individual field, i.e.

$field = $modules->get("InputfieldText");

$field->setMarkup([
    'item_content' => "{out}<span class='different-span'></span>"
]);

Calls the same method, setting $markup within inputFieldWrapper.php and adjusting the output of every inputFieldWrapper

Therefore I was hoping for a way of appending to the inputfield or wrapper without it being global

It's just another Inputfield to be used with processwire's form api. Instead of rendering a "real" inputfield you can just set a string (markup) to it, that will then be plainly rendered, without looking at it. What I just noticed: I was wrong above, just using it for opening and closing markup won't work as InputfieldMarkup is also wrapped in the "wrappingMarkup" that every other Inputifield does get, too.

Edit: The holy bible for working with the form api: https://processwire.com/talk/topic/2089-create-simple-forms-using-api/

but it refers to coding in the admin? i haven't done any form coding yet so that's why i have no idea ;) my question was more about if there was a kind of installable inputfield (click, click solution) with a textarea that you can then place to a template (click, click) and then it renders some markup for you.

edit: InputfieldMarkup is not that kind of a field, is it?

      Hi all,
      Running into an odd error that I can't seem to get my head around.
      We have 2 separately created Formbuilder forms sitting on a single page.
      But we keep experiencing weird results with them, originally we couldn't get one of the forms to ever submit so we ended up disabling CSRF for them which let us get around this issue.
      However it then causes a problem in that with CSRF disabled, one of forms always records 2 entries on submission. Just a straight duplicate within the entries for that form.
      So trying to stop this happening we tried enabling CSRF again and although that does stop the duplicated entry, it ends up giving really weird feedback such as the attached screengrab.
      Hazarding a guess I assume whatever is trigger on submission is firing twice because of the presence of the second form, but I have no idea why this would be the case as they are 2 seperately named forms?
      Any ideas?

      I have a a form in my site footer that can be accessed anywhere on site, I've added the form in the _inc.php file and added the render in the pages footer.php. However, this works well on the homepage e.g. you can submit said form and get a thank you on reload, doesnt work at all on other pages... Just lots like a fresh reload. Any thing im doing wrong here or ways to diagnose as there isn't an error log for formbuilder etc...?

      I have a few web forms which require testing on a weekly basis and I don't want the recipients (administrators) to receive these test emails.
      What would be a good way to test approx 15 forms from the front end and have the test delivered a list of secondary administrator recipients?
      I'm thinking that I could have some kind of config file which watches for a trigger word or email and then understands that it's a test and to bypass the normal admins?
      All of the forms ask for an email address so I could setup an email such as 'testform@email.not' etc which my config file (hook?) would watch for.
      Or is there a better way to do this?
      Additionally, I have a few extra requirements...
      Forms should goto an alternative success page. This is because I don't want my test to skew my Google Analytics conversion tracking Forms would need to be tested from the front-end and not the PW admin area Any advice appreciated.
      BTW I realise this should be posted in the proper FormBuilder support forum. I am in the process of renewing my license for access to that support forum.

      What is the best practice for having a form (only accessible to a logged in user) save the user's progress between sections of the form? Fieldsets? Multiple forms?
      Use case: I have a very long application form that would take 30 minutes for the applicant to fill out and I would hate for all progress to be lost due to user error. The progress needs to be logged into the user's page.
      Thanks!

      I'm trying to implement a front-end image upload form for user profile pictures, to a field called 'profile_picture'. The code is based on the various examples found around these forums but isn't yet 100% right.
      The form successfully submits the image to the server and updates the field in the dashboard. When you submit the firm, the page reloads and uploads the image but the template still loads the old image path (now broken path as the old image has been removed).
      I can only get the new image to show if I hit enter in the address bar forcing the page to reload.
      Any ideas? Is it a caching issue, or something to do with the order of the script? It makes no difference if I call the image after the upload form.
      <?php //Display current user image $userImg = $user->profile_picture->first(); echo '<img src="'.$userImg->url.'">'; $upload_path = $config->paths->assets . "files/avatar_uploads/"; $f = new WireUpload('userimage'); $f->setMaxFiles(1); $f->setMaxFileSize(1*1024*1024); $f->setOverwrite(true); $f->setDestinationPath($upload_path); $f->setValidExtensions(array('jpg', 'jpeg', 'png', 'gif')); if($input->post->form_submit) { if(!is_dir($upload_path)) { if(!wireMkdir($upload_path)) throw new WireException("No upload path!"); } $files = $f->execute(); if ($f->getErrors()) { foreach($files as $filename) @unlink($upload_path . $filename); foreach($f->getErrors() as $e) echo $e; } else { $user->of(false); $user->profile_picture->removeAll(); // wirearray (line added by @horst: explanation is three posts beneath) $user->profile_picture = $upload_path . $files[0]; $user->save(); $user->of(true); @unlink($upload_path . $files[0]); } } ?> <form class="forum-form" accept-charset="utf-8" action="./" method="post" enctype="multipart/form-data" > <input type="file" id="attach" name="userimage" accept="image/jpg,image/jpeg,image/gif,image/png" /> <input type="submit" name="form_submit" value="Submit"/> </form>
