How to dynamically populate a choices widget in symfony? - forms

Suppose there is an image_url column in database.
I want the user to choose from several recommended images,which is something like this:
<input type="radio" value="domain.com/path_to_img1" name="image_url" />
<img src="domain.com/path_to_img1" />
<input type="radio" value="domain.com/path_to_img2" name="image_url" />
<img src="domain.com/path_to_img2" />
Where the image urls are generated on the fly.
How to do this in a symfony flavor by sfForm?
I tried this:
$form->widgetSchema['key'] = new sfWidgetFormSelect(...)
But get a fatal error:
Cannot access protected property
But what's the exact way to do this?

Well, standart approach is to write a widget.
In your concrete case it seems you actually want to perform a choice, right? So you have to implement another sfWidgetFormChoice renderer. To do that, inherit sfWidgetFormSelectRadio (let's call them sfWidgetFormSelectRadioImage) to learn them to render labels as <img> tags. Then ask sfWidgetFormChoice explicitly to render itself with sfWidgetFormSelectRadioImage class, and that should be all.

In your form configuration insert the following:
$this->widgetSchema['choices'] = new sfWidgetFormChoice (array('choices' => $custom_values_array));

TYPO3 merge list and edit

I've got a TYPO3 backend module which lists a lot of elements. Now, I want to include in my list the edit form, but that doesn't work well at the moment.
Rendering is good, but if I send the form, I get the error:
Required argument "note" is not set.
My code looks like this:
<f:for each="{notes}" as="note">
<f:form action="update" name="note" object="{note}">
<textarea class="form-control gettooltip" rows="1" placeholder="Kommentar" title="Kommentar zur Note">{note.kommentar}</textarea>
</f:form>
</f:for>
How can I merge these two views correctly?
Your code cannot work because your textarea doesn't have a property (or you don't use the <f:form.textarea ViewHelper).
If you property map $note in your controller, the property must be passed to Fluid with the prefixed extension name and plugin name. This is done automatically when using the "property" argument of the textarea ViewHelper. The name attribute will then be:
<textarea name="tx_myext_myplugin[note]"...
Thîs will map to $note in the controller.
So if you don't use the ViewHelper, you need to manually prefix the name attribute to create an output like printed just above.
If you're planning to update multiple objects of the of the same kind in one request, this won't because because there is an Extbase limitation.
You could do the following:
Use a submit button for each note and save/reload the changes through AJAX.
<f:for each="{notes}" as="note">
<f:form action="update" name="note" object="{note}">
<f:form.textarea class="form-control gettooltip" placeholder="Kommentar" property="kommentar">{note.kommentar}</f:form.textarea>
<f:form.submit value="Update" />
</f:form>
</f:for>
Then you intercept the submit click, submit the form through AJAX and set the new content to the textarea.
If you want to have one form for all objects, you will need to prefix the fields
<f:form action="update" name="note">
<f:for each="{notes}" as="note">
<f:form.textarea class="form-control gettooltip" placeholder="Kommentar" name="note[note{note.uid}][kommentar]">{note.kommentar}</f:form.textarea>
</f:for>
<f:form.submit value="Update" />
</f:form>
You will then have an array of values and need to iterate in your controller and manually persist the changes.
For your problem - as #lorenz answered you need to use viewhelpers for rendering fields OR at least use valid name attributes for your fields...
Anyway, I'm wondering why do you want to reinvent the wheel - especially while creating BE modules, the fastest, easiest and most elegant way is... using TYPO3 forms. They handle many things, relations, localization, validation, RTE etc, etc. What's more you can also add own type of field to TCA and process with your own PHP and JS - very rare situation, but may be used i.e. for adding GoogleMap field,
#see: user type in TCA
Finally all you need to open the record from your BE module is creating proper link - which can be easily copied from List module (right click on the yellow pencil next to your record and copy the code), sample:
<a href="#" onclick="window.location.href='alt_doc.php?returnUrl='+T3_THIS_LOCATION+'&edit[fe_users][1234]=edit'; return false;" title="Edit user">
<span title="" class="t3-icon t3-icon-actions t3-icon-actions-document t3-icon-document-open"> </span>
</a>
Where fe_users is table name and 1234 is record uid.
alt_doc.php?returnUrl='+T3_THIS_LOCATION part handles returning to the place from which edit was started, so it will be your module again including all GET params selected by admin before editing.
For creating new user
<a href="#" onclick="window.location.href='alt_doc.php?returnUrl='+T3_THIS_LOCATION+'&edit[fe_users][6789]=new'; return false;" title="New record">
<span class="t3-icon t3-icon-actions t3-icon-actions-document t3-icon-document-new"> </span>
</a>
In this case 6789 is a PID (uid of the page where the user should be created...
You can even set some default values when creating records from your own module using params in your new link:
&defVals[table_name][field_name]=value
sample
<a href="#" onclick="window.location.href='alt_doc.php?returnUrl='+T3_THIS_LOCATION+'&edit[fe_users][6789]=new&defVals[fe_users][tx_extbase_type]=Tx_MyExt_People&defVals[fe_users][usergroup]=1'; return false;" title="New record">
<span class="t3-icon t3-icon-actions t3-icon-actions-document t3-icon-document-new"> </span>
</a>

Zend Form text element with array notation issue

I'm using Zend_Form and have got stuck in a situation. I have an array of some values like below :
$feeTypes = array(1,2,3,4);
and want to create 6 text elements in zend form that should be rendered like following:
<input type="text" name="class_fee_type[1]" />
<input type="text" name="class_fee_type[2]" />
<input type="text" name="class_fee_type[3]" />
<input type="text" name="class_fee_type[4]" />
I tried the following code but don't know that how to associate the above $feeType array.
$class_fee_type = $this->CreateElement('text','class_fee_type')
->setRequired(false)
->setAllowEmpty(false)
->setIsArray(true)
->setRegisterInArrayValidator(false)
->setDecorators(array( array('ViewHelper')
));
I'm not using any subform in this form. This is absolutely simple zend form.
Thanks.
I'm talking from ZF1 point of view:
It seems like there is no standard way of doing what you need. So I would recommend write your own form element and element view helper for that. And passing your indexes array as options to element.
Note: to use setRegisterInArrayValidator - your Zend form element should extend Zend_Form_Element_Multi.

How do I replace an attribute value for attribute with multiple values in Wicket?

My class attribute has two CSS class values. The HTML starts out like this:
<input type="button" wicket:id="rowButton" class="jelly-button greenGradient"/>
And I want to dynamically change it to this:
<input type="button" wicket:id="rowButton" class="jelly-button redGradient"/>
Currently I am doing this:
component.add(new SimpleAttributeModifier("class", "jelly-button redGradient"));
What is the best way to do this in Wicket? There must be a more 'proper' way to do this than what I have done above.
Instead of using an attribute modifier with fixed text you could use an attribute appender with the text retrieved from a model. To change the class, just change the model's value. For example:
Model<String> gradientModel = new Model<String>("greenGradient");
...
component.add(AttributeModifier.append("class", gradientModel));
in the markup just have
<input type="button" wicket:id="rowButton" class="jelly-button"/>
Then when it is time to change the gradient use
gradientModel.setObject("redGradient");
or
gradientModel.setObject("greenGradient");
The example in the javadoc below explains it well

Generate <input type="search" /> using Play! framework

I'm using the Play Framework. I want to use the HTML5 input type 'search'. So, I want to output:
<input type="search" />
I've tried:
#inputText(field = myForm("myField"), 'type -> "search")
but it still kept the type="input"
the method inputText represents an HTML input text (see the source code here).
You have to define your own template to define the input of type search. Take a look at the Play documentation.
#helper.input(myForm("myField")) { (id, name, value, args) =>
<input type="search" name="#name" id="#id" #toHtmlArgs(args)>
}
Most probably your search field will not use many typical things from common form element (like constraints or error messages) so you can just use plain HTML to insert it, and add field's value in the proper attribute (if required at all):
<input type="search" name="myField" value="#myForm("myField").value" />
If it's just a search form (with this only field) you even don't need to wrap it with the Form class
(of course Nico's suggest is advisable in more sophisticated scenarios)
Some helpers you're looking for are avalaible in a play 2 module. The html5 input helpers are not in the core part of the framework because play authors want to keep it light.
Here is the module page on github : https://github.com/loicdescotte/Play2-HTML5Tags

Play 2.0 Nested forms: generate <input id="email"> instead of <input id="user_email">

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.
