Does anybody know of a simple jQuery form processing tutorial that actually works?
I have a form I want to process via jQuery/Ajax nothing difficult in PHP but in jQuery and AJAX can I get it to work - no, all the tutorials are based round sending e-mails (or just lists of more lists of more lists of tutorials - hate those)
All I want to do is learn how to send a form via jQuery and AJAX to another page, save the data in a DB without having to leave the first page. I have tried all sorts but nothing works properly. Here is my form:
<form id="form">
<input type="text" name="abc" />
<input type="text" name="def"/>
<input type="text" name="ghi"/>
<input type="submit" name="try" id="try" />
</form>
Now what do I actually do? Sounds silly I know (and I guess I'll get another -1 star for this question) but I will be honest a GOOD simple tutorial would be really useful not just to me but to the others. I know php but jQuery/Ajax - just don't know/understand. I will not be alone
This is one of the good tutorials on how to submit forms using ajax and php.
This link is a reference teaching how to submit forms via jQuery/AJAX. Have the form post to a PHP page to handle the form data.
In short, your jQuery code would look similar to this:
$("#form").submit( function()
{
// Handle validation or any extra data here.
// Return true if validation passed and the data should be posted
// Return false if the form should not be submitted
// You can also do any extra work here that you like before returning,
// including changing something on the page or showing the user a message.
}
There's a cracking plugin for this:
http://plugins.jquery.com/project/form/
It's as easy as:
$('#myForm').ajaxForm(function() {
alert("Thank you for your comment!");
});

I have a (hopefully) simple problem:
I want to use a simple html form in a sympony2 project. The Problem is, that noting is sent by get through the form.
The Url after sending the form is: localhost:8888/de/search_art?
you see... there is no string after the ? !!!
The form looks like this:
<form class="navbar-form" role="search" method="get" action="{{ path('func_search_art') }}">
<input type="text">
<button type="submit" class="btn btn-default">Send</button>
</form>
This is my routing:
func_search_art:
path: /search_art/
defaults: { _controller: FuncSearchBundle:Search:SearchArt }
I don't want to do something within a controller for it, because it is in the navbar and for this it has to appear in every page. I don't want to initialize a form variable in every controller of the page for a simple navbar search field.
Is there a possiblity to create a simple form like this in symfony2 without using a form builder and so on ... ?

Yes, you can safely keep your form written in twig in the form you presented it. No need to create a form builder in every controller and send the form to twig. The only place you will have to build it is the SearchArtAction method from SearchController, where you have the handling functionality for this form.
Also you need to give a name to your text input.
<form class="navbar-form" role="search" method="get" action="{{ path('func_search_art') }}">
<input type="text" name="q">
<button type="submit" class="btn btn-default">Send</button>
</form>
Because your input lacks the name attribute , which is the relevant attribute to create the post data/query string.
You can't it will give you: "The CSRF token is invalid. Please try to resubmit the form". Regardless of that it actually work without it. For some reason Symfony serialized the forms. I particularly hate the fact that I need the form object to use forms, in many cases I found it overkill. Your $form->isValid will also failed, but the $form->isSubmitted() will not. One of the reasons I hate the form object is how tedious it is to populate a drop down with an EntityType, instead of making simple symfony manage to make the process a damn nightmare.
I have this
<form id="form_837299" class="appnitro" method="post" action="insert.php"> <paper-input label="Title" name="title" maxlength="255">
</paper-input>
<paper-input floatinglabel multiline label="text" name="text"></paper-input>
<li class="buttons">
<input type="hidden" name="form_id" value="837299" />
<input id="saveForm" class="button_text" type="submit" name="submit" value="Submit" />
</li>
</ul>
</form>
I have problem with POST data - nothing is sended in "text" and "title" (all in paper-input).
I modified the template and attribute "name" now is in one div, which Polymer created. But no data are sent.
print_r($_POST); shows me only this:
Array ( [form_id] => 837299 [submit] => Submit )
Anybody knows how use Polymer and Material UI on form?
Only elements that extend native form elements automatically get submitted with forms. paper-input extends core-input which has an input inside it as opposed to extending it. See this mailing list discussion for additional discussion and this StackOverflow post for possible solutions.
Something like this jsbin maybe?
Update: Here's the same thing in web component form.
Update: Looks like the creator of ajax-form has added this functionality.
Update: Also consider using iron-form.
According to the Polymer docs the way to do this is to just create a regular form input and wrap it in the <paper-input-decorator>
https://www.polymer-project.org/docs/elements/paper-elements.html#paper-input
I've tried it out and it works fine. Some better form support would be cool, but oh well. This stuff still kind of rocks.
UPDATE: I've built a bower package (polymer-rails-forms) to deal with forms in polymer, tailored specifically to the ActiveRecord input naming scheme but it will work with any old form really. It's still relatively new, but it covers most input types, basic validations, xhr and non-xhr submits and has a couple cool extras like image, json, and location* fields.
the location fields depend on the Google Map Places API
I have a site hosted with Shopify. I would like to implement a form that posts to an external url. This is a custom form. My original thought is that I could just create a new page and add a form similar to these examples here - http://wiki.shopify.com/Contact_And_Signup_Forms#Signup_Forms
But, I don't see an option to post to an external url. I am completely new to Shopify. I had hoped that being a rails programmer would have helped, but it looks like I need to work with the liquid template system and not rails.
Any assistance would be appreciated.
Instead of using the liquid form tag, just use straight HTML and specify an action for your form that points to an external URL.
Example:
<form action="http://your-url.com" method="post">
<input type="text" name="email_address">
<input type="submit" value="Go!">
</form>
The above example will POST to http://your-url.com.
I've been playing around with Play framework for a few days, and it seems really cool. However, I ran into some problems when I wanted to have a form on a page, post the form and show the results on the same page (with the form still on the page). Does anybody know if this is possible with Play, and if so: how?
EDIT:
I should have explained better. The form is a search-style form not a save-style form. I want to be able to search for something, have the results come up under the form and still have the values the user filled in in the form (as it is if you type in something that don't validate. I have tried to set values on the params object directly in the search action, but it disappears when the search action calls the new action.
Second try of an answer untested, hope this fits to your problem.
public static void search(String criteria1, String criteria2) {
....
params.flash();
}
search.gsp
<p id="criteria1-field">
<label for="criteria1">&{'criteria1'}</label>
<input type="text" name="criteria1" id="criteria1" value="${flash.criteria1}" />
</p>
<p id="criteria2-field">
<label for="criteria2">&{'criteria2'}</label>
<input type="text" name="criteria2" id="criteria2" value="${flash.criteria2}" />
</p>
Well this is quite simple. You put into the routes.conf a
GET /myPageWithForm MyController.read
POST /myPageWithForm MyController.save
In read you read the data and render your page with the form. In save you save the data and redirect to read via read();
Hope this answers your question.
I'm trying to do a submit via ajax of a form that contains a file element.
<form id="classic_upload" enctype="multipart/form-data>
<input type="file" name="file" id="file"/>
<br/>
<!-- ...other inputs...-->
<button type="button" id="classic_save"> Send </button>
</form>
What I need to do is to submit this form and check if the file fulfills some requirements, so I wrote an ajax submit for this form
$('#classic_save').click(function(){
$.ajax({
type:"POST",
url:'<g:createLink action="classicUploadFile" controller="scan"/>',
success: function(msg){
alert("Data Loaded: " + msg);
}
});
});
However, I have no idea how to send the file through ajax.
Some context
Originally we were using swfUpload for this. However, we ran into some trouble with https and some certificate issues. So we decided to implement a basic html fallback. Plugins are nice, but we need to guarantee that this fall back is bullet proof (thinking of google mail "classic upload").
Any thoughts? Are iframes the way to go (read somewhere google mail uses them for their classic upload)
Thanks in advance.
If you like, there is jQuery Uploadify plugin to do exactly what you are looking for other than other great features.
I use the jQuery AJAX form plugin on my site to upload files.
Here you'll find a really good example/tutorial how to upload one file http://www.phpletter.com/Demo/AjaxFileUpload-Demo/
Hope it works for you.
Cheers
