I need to write a module that sends order data to an epayment service, similar to say, paypal. They need the data to be submitted from a form with elements that look something like this (notice the duplicate name):
<input name="ORDER_PNAME[]" type="hidden" value="CD Player">
<input name="ORDER_PNAME[]" type="hidden" value="Geanta voiaj 2L">
This makes it impossible to override the form by simply editing $form in module_form_alter() because "ORDER_PNAME[]" would be a duplicate key in $form.
So I need to bypass the whole drupal form handling system. I looked and found that I could overwrite the $form variable in uc_cart_checkout_review with plain html form data (see http://api.ubercart.org/api/function/uc_cart_checkout_review/2 line 4).
What would be the correct way to do this?
On the rights of a workaround:
you can add the necessary form elements using markup element:
$form['your_name'] = array(
'#type' => 'markup',
'#value' => '<input name="ORDER_PNAME[]" type="hidden" value="CD Player">
<input name="ORDER_PNAME[]" type="hidden" value="Geanta voiaj 2L">',
);
If you don't need to redirect user to that e-payment service page, just send data, you can use curl to post the necessary data. A related question: Auto Submitting a form (cURL).

In my Rails 4 project I want to add 2 fields to all the forms for a controller on the server side.
I'd like to add this to all of my forms for a controller.
input name="authenticity_token" type="hidden" value='=form_authenticity_token'
input name="profilePage" type="hidden" value='#{params[:action]}'
Each view has one form.
You could make it a partial:
#_csrf.html.slim
input name="authenticity_token" type="hidden"value='=form_authenticity_token'
input name="profilePage" type="hidden" value='#{params[:action]}'
And then render it in each form:
= render 'csrf'
Does anybody know how to validate the file type input.
I have modified (hard coded) the class.vf_file.php input.
$strOutput .= "<input accept=\".pdf,.doc,.docx\" etc----/>\n";
This helps with Google Chrome, but Safari, Firefox ignore the modifications
Preventing users to submit the form if any other type of file is detected would be the ideal solution.
Thank you
I would recommend using a third party file uploading library like Plupload. We always use ValidForm Builder together with Plupload; works like a charm.
However you can use the meta array to implement custom attributes in the <input> tag without having to hardcode anything:
$objForm->addField(
"upload-document",
"Upload Document",
ValidForm::VFORM_FILE,
array(), // Validation array
array(), // Error handling array
array( // Meta array
"fielddata-extensions" => "pdf,doc,docx"
)
);
By prefixing meta keys with the 'field' prefix, you add that specific meta to the <input> field itself instead of it's wrapping <div class='vf__optional'></div>
The above example will output:
<div class="vf__optional">
<label for="upload-image">Upload Image</label>
<input type="hidden" name="MAX_FILE_SIZE" value="2097152">
<input type="file" value="" name="upload-image[]" id="upload-image" class="vf__file" data-extensions="pdf,doc,docx">
</div>
So using a combination of meta and a third party file upload handler, you can actually to pretty cool stuff.
That being said -- I must admit that the file upload field didn't get as much attention as the other field types lately.
In my Angular app I'm having a form bound to a model. The form does not have fields for all model properties.
When the user hits the submit button I want to post the form the traditional way, not as AJAX request (I have to deal with an already existing server side script).
That basically works if I add a action to the form. But it obviously only submits the form with its present fields as it is, not the whole model just like it's done when using the $http service.
And additionally it does not create name attributes.
How could I submit the form the old-school way with the full model data? Do I have to create the missing form fields on my own or is there a way to let Angular do that for me?
<script>
angular.module('foobar', []).controller('ContentCtrl', ['$scope', function($scope) {
$scope.content = {
'title': 'Foo',
'subtitle': 'Bar',
'text': 'desc' // this field is missing in the form itself and therefore is not submitted
};
}]);
</script>
<form action="http://postcatcher.in/catchers/521c6510429f840200000169" method="post" ng-controller="ContentCtrl">
<input type="text" name="est" ng-model="content.title" value="asdf">
<input type="text" ng-model="content.subtitle">
<button>submit</button>
see post result
</form>
Here's a plunker: http://plnkr.co/edit/5XYGH9hTe7cpchSFWbTK
Angular doesn't do anything special when you have a form with an action defined. It's pure html form submission with exactly the fields that are defined.
Normally you would use:
<input type="hidden" ng-model="content.desc">
but angular currently (1.2.0rc1) still doesn't support ng-model binding to hidden inputs.
The workaround is this:
<input type="text" name="text" ng-model="content.text" ng-hide="true">
I am somewhat of a novice with CGI Perl and am working on a web app that uses 'mode' and 'action' variables to determine which pages load.
$mode = param('mode');
$action = param('action');
if ($mode eq 'page1') {
if ($action 'eq') {
&performAction;
}
displayPage1;
}
elsif ($mode eq 'page2') {
&displayPage2
}
During development I have been having trouble figuring out the best way to set these variables when trying to navigate to different modes/actions after a form submit.
In some cases, putting a hidden value in the form will work
hidden(-name=>'action',-value=>'save')
but sometimes it will not. In case of the latter, putting param('action',"save") before the form will make the action change when the form is submitted.
I am unable to figure out why this happens though, are there factors that affect these two variables that I am unaware of?
What I now need to do is have two buttons on the same form, one which will just set the action to save the form data, and another which will save the form data but navigate to another mode/page with that form data.
If anyone could at least point me in the right direction for what I should be researching I would be greatly appreciative.
By default the CGI module implements a state-preserving behavior called "sticky" fields. The way this works is that if you are regenerating a form, the methods that generate the form field values will interrogate param() to see if similarly-named parameters are present in the query string. If they find a like-named parameter, they will use it to set their default values.
You want
hidden(-name=>'action', -value=>$new_value, -override=>1)
or
hidden(-name=>'action', -value=>'default_value')
param('hidden_name', $new_value);
This is a try , not sure if it would work.
Try setting hidden variable before button and changing it before every button, so the new value should be taken.
For ex:
<input type='hidden' name='op' value='save'/>
<input type='submit' name='Save Form' value='SaveForm'/>
<input type='hidden' name='op' value='submit'/>
<input type='submit' name='Submit Form' value='SubmitForm'/>
<input type='hidden' name='op' value='cancel'/>
<input type='submit' name='Cancel Form' value='CancelForm'/>
You can check for hidden variable 'op' in perl script.
Posted this to Play user group; I account for the sole view, so hoping to get a view, or perhaps even an answer ;-)
Nested forms are great, but there's one glitch that adds boilerplate to either javascript or scala templates.
For example, given:
#inputText(field = _form("user.email"),
'_label-> "Email Address*",
'class-> "required email",
'placeholder-> "jdoe#gmail.com"
)
the generated input field is something like:
<input id="user_email" name="user.email" ...>
Now, when you want to validate the email address client-side you then have to reference DOM id: $('#user_email')
Where $('#email') would be more natural.
I know I can set the id attrib manually in the template but would prefer to, by default, have the nested name (user in this case) stripped out from the id attrib.
Looking in github views helper directory, I am not finding where I can get access to the generated id (i.e. which file I need to overload and how).
Anyone know how to pull this off and/or have a better approach?
Here is where the field's ID is auto-generated:
https://github.com/playframework/Play20/blob/master/framework/src/play/src/main/scala/play/api/data/Form.scala#L274
There's not really any way you can override that behaviour, but you could write your own #inputText helper that strips the "user_" part from the ID when generating the HTML.
Basically copy-paste the default helper and replace
<input type="text" id="#id" ...
with your own code, e.g.
<input type="text" id="#processFieldId(id)" ...
or (untested!):
<input type="text" id="#(id.split('_').last)" ...
Then just import your custom helper in your template, and use it just like you would use #inputText.
