I have a spring 3 application with select list.
<form:select path="objectlist" >
<c:forEach items="${objects}" var="objects">
<form:option value="${objects}" label="${objects.description}" >
</form:option>
</c:forEach>
</form:select>
There objects are queried from database. Path is Object class attribute.
I would like to print the description of an object user has chosen.
When I use ${form.objects} - I get an object instance written, but when adding .description there, it is null. What I'm missing here?
In <c:foreach> tag you should specify the variable where it will temporary store each array element. For some reason you are using same name as an array and at some point the two variables collide with each other.
Try this:
<c:forEach items="${objects}" var="object"> <%-- Notice there is no letter S at the end --%>
<form:option value="${objects}" label="${object.description}" > <%-- Here too --%>
</form:option>
</c:forEach>

I am using this Helhum example for uploading images from the frontend, which is located on the following link
https://github.com/helhum/upload_example
If we check its form fields in partial file on location
https://github.com/helhum/upload_example/blob/master/Resources/Private/Partials/Example/FormFields.html
there is given two uploads option which are following
{namespace h=Helhum\UploadExample\ViewHelpers}
<label for="title">
<f:translate key="tx_uploadexample_domain_model_example.title" /> <span class="required">(required)</span>
</label><br />
<f:form.textfield property="title" /><br />
<label for="image">
<f:translate key="tx_uploadexample_domain_model_example.image" />
</label><br />
<h:form.upload property="image" >
<f:if condition="{resource}">
<f:image image="{resource}" alt="" width="50"/>
</f:if>
</h:form.upload><br />
<label for="image_collection">
<f:translate key="tx_uploadexample_domain_model_example.image_collection" />
</label><br />
Here for the property="imageCollection.0" if I make it multiple="multiple" then it give me the following error
1297759968: Exception while property mapping at property path "imageCollection": PHP Warning: spl_object_hash() expects parameter 1
to be object, null given in
/var/www/webroot/typo3_src-7.6.14/typo3/sysext/extbase/Classes/Persistence/ObjectStorage.php line 155 (More information)
And if I remove the 0 and just try to click a botton then it even not generate a form and give me the following error
1297759968: Exception while property mapping at property path "": The source is not of type string, array, float, integer or boolean, but of
type "object" (More information)
So long story in short, how can I fix this example for multiple images uploading. I try to used without helper function just used a standerd fluid function <f:form:upload> it still give me a same error. please somebody can help me in sort out this problem.
There is a cq page and in the page there are many component. In one component we have HTML form code. After submitting form data ,i need to set all value in PageContext and use these value in other component on same page.
To achieve this I have created component named "MySamplecomponent". and in put all html code as below.Also i have created a POST.jsp under same component.
Mysamplecompnent.jsp code
<%#include file="/libs/foundation/global.jsp"%>
<%
//String collapsed = properties.get("selection","");
String collapsed= request.getParameter("testKey");
out.println("value++"+collapsed);
String category= request.getParameter("skill");
out.println("Category++"+category);
pageContext.setAttribute("collapsed1",collapsed,PageContext.REQUEST_SCOPE);
%>
<form name="form1" id="form1" action="${currentPage.path}.html" method="post">
<input type ="text" name="testKey" id="testKey" value="collapsed" />
<input type ="hidden" name="pathValue" id="pathValue" value="myValue" />
<select name="skill" style="display:block">
<option value="1">Cricket</option>
<option value="2">Volley ball</option>
<option value="3">Tennis</option>
</select>
<input type="radio" name="ravi" id="radiobutton" value="success" > radiobutton<br>
<input id="SubmitButton" name="SubmitButton" type="submit" value="SubmitButton" onclick="javascript:location.href='#'" />
</form>
After clicking on submit button getting below error
Error while processing /content/myPage/

First of all, I believe you mean PageContent under PageContext. If you want to use Sling Post Servlet, you need to change the action.
${currentPage.path} refers to Page node and not PageContent node. Page node has pretty strict restrictions for properties and you can not put there any custom props, like testKey. So to make your code work just replace your action attribute with ${currentPage.path}/jcr:content and it will work.
Use JQuery and AJAX. See this article:
http://scottsdigitalcommunity.blogspot.ca/2013/06/posting-form-data-to-adobe-cq-using.html
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>
Please see this similar question How to handle two different submit operation from same form in a spring controller
In my case it is drop down button.I tried a lot but couldn't find a solution.So how can I handle the different submit operatiins from a single form in the spring controller.
<form:form action="someURL">
<form:select path="cfgObjectType" cssClass="styled-select"
onchange="submit()">
<form:option value="Application" >Application</form:option>
<form:option value="Agent" >Agent</form:option>
<form:option value="all" >all</form:option>
</form:select>
<form:select path="applnType" cssClass="styled-select"
onchange="submit()">
<form:option value="all" >All</form:option>
<form:option value="one" >one</form:option>
<form:option value="two" >two</form:option>
</form:select>
</form:form>
Hope our stack users will help me.
If you use a standard submit button there is a formaction attribute that you can use to specify the alternate action.
http://www.w3.org/wiki/HTML/Elements/input/submit#HTML_Attributes
There is no attribute for regular form options to support changing the action. Inside the onChange event, instead of supplying submit() as the function, create your own JavaScript function that changes the form action based on the selected value.
First, give your form a name.
<form:form action="someURL" name="formname">
Then reference the full name in the select onchange method:
<form:select path="applnType" cssClass="styled-select"
onchange="document.formname.submit()">
I'm creating a form in which user will be able to choose (among the others) the factory of a product.
Each factory is identified by and ID and has specific address.
I want to use custom label in following code:
<form:select items="${factories}" path="factory" itemValue="id" itemLabel="..."/>
At first i tried using Spring Formatter functionality (org.springframework.format.Formatter interface), but when I did this, and when I removed "itemLabel" attribute to have it displayed automatically via Formatter):
<form:select items="${factories}" path="factory" itemValue="id"/>
But then It wasn't selecting proper value if it was set (in case of editing).
Then I tried to:
<form:select path="factory" itemValue="id">
<c:forEach ...>
<form:option value="${factory.id}" label="${factory.address.city} ${factory.address.street}"
</c:foreach>
</form:select>
But as in earlier solution spring was not selecting proper value that was set in model.
My question is:
Is it possible to format entity in a way, that form:select works properly, when a value of select field is not the same as its label.
I had the same problem, the trouble is the form:option value and label maps directly to a property rather than having the flexibility to specify jstl.
So you have to hand crank the html, to something like:
<select name="factory">
<c:forEach var="factory" items="${factories}" >
<option value="${factory.id}" label="${factory.address.city} ${factory.address.street}"/>
</c:forEach>
</select>
Spring will pick up the 'path' based on the name attribute('factory' in this case), as it will try and map to the model object you are using automatically.
Another way is to add another field to the model to concatenate and format label as you wish. And if its an #Entity object then make the field #Transient.
You can also override toString() method in Factory class
#Override
public String toString() {
return "desired string";
}
Then in your jsp
<form:select items="${factories}" itemValue="id" path="factory"/>
