I am trying to pass a variable from my classic asp page to ssrs. When I put in a literal value for the parameter, such as 296, it works fine. But I want to put in a variable that is sent by the URL so that it works in different ways for different people who are logged in. So, instead of a URL that is http://servername.net/reportserver....rs:Command=Render&Agency=296 (for the agency that is number 296) I want to use a variable that I have set to the agency of the person who has logged in. Let's say the variable is pAgency. I have tried Agency=" #pAgency (I set pAgency = to the logged in person's agency) and all sorts of other combinations, and have searched the web, but find no answer for this. I've even tried session variables but, no go. You must be able to do this but...
Thanks for any help you can give. Cheers!
That is not how a rest URI works to my knowledge. You need to build the string and present it first fully formed, not define a variable on it. You could do somthing in code like (using HTML Form as a base)
In the example below there are four clear things to understand:
A. The 'action' in the form must be the webservice location of a report and do a post to self. (Or you can do an iframe element potentialy but I have not messed with that as much)
B. The 'input' element is text based but you MUST match the id and name to the name of your parameter passing in.
C. The 'select' element gives a user 'option's of save methods to output directly to common types.
D. The 'input' for a type of 'submit' ensure the form will post to itself with the data prescribed.
<!DOCTYPE HTML>
<html>
<head>
<title>SSRS Tester</title>
</head>
<body>
<form id="SSRSRender" action="http:// (reportservername)/ReportServer?/(pathtoreport)" method="post" target="_self">
<H3>Enter some detail for the report to render</H3>
My Variable 'Test': <input type="text" id="Test" name="Test">
<br/>
My outputs:
<select ID="rs:format" name="rs:format" size=1>
<option value="HTML4.0">HTML 4</option>
<option value="IMAGE">Tiff Image</option>
<option value="PDF">PDF</option>
</select>
<br/>
<input type="submit" value="Render Report">
</form>
</body>
</html>
If you want to do more types of input variables to dynamically get SSRS to render as you want outside of the SSRS landing page you need to determine if you want to use:
The service with some front end with scripting like javascript with HTML
Something more easy to control will pre built tools like 'Report Viewer' with ASP.NET or a client application in C# or VB.NET
Create the service proxy yourself in a class library and do the calls in code directly as well as the formatting
Trying to create a rest URI programatically is better done by contacting the service and using built in methods IMHO rather than trying to make a string. It may be a little more of a learning curve but it will help you in the end.

I am getting two problems:
How to fill field in form in html using thymeleaf? I have form like this and would like to fill fields with current values (th:value="${}" - not working for me):
<form th:action="#{/offences/edit}" method="post" th:object="${createOffenceForm}"> <input th:field="*{name}" th:value="${currentOffence.name}"/> <input th:field="*{penaltyPoints}" th:value="${currentOffence.penaltyPoints}"/> <input th:field="*{amountOfFine}" th:value="${currentOffence.amountOfFine}"/> <button type="submit">UPDATE</button> </form>
The problem is with loading css styles to html when I redirect to the site with path variable. For example i created html with two buttons. First one is hardcoded:
<a th:href="#{/offences/test}" class="link" style="text-decoration: none"><button class="buttonOK" type="submit">EDIT</button></a>
after redirect my site looks like this (everything works, it should be like that):
`
and here is after second button - redirect with path variable:
<a th:href="#{'/offences/edit/' + ${offence.id}}" class="link" style="text-decoration: none"><button class="buttonOK" type="submit">EDIT</button></a>
and view after load:
For the issue with your form data not being filled, this is because th:field and th:value are not meant to be used at the same time. So th:field ends up overwriting you value.
In your case I would suggest either manualy setting name (and id) or replacing th:object with the a filled version of the bean you want to return and only using th:field
As for the second issue it looks like a faulty fragment return on a post call to me but need to atleast have the controller functions and more complete html to say anything about that. And in general it's advisable to have 1 question per problem and not bundle things.
Ok so i found soultion.
To fill fields in form I only had to add to ModelMap form with fields.
Something like this and thymeleaf autofilled fields in html.
modelMap.addAttribute("createOffenceForm", new CreateOffenceForm(offenceDTO.getName(), offenceDTO.getPenaltyPoints(), offenceDTO.getAmountOfFine()));
Second solution is simple too. When changed mapping in Controller from #GetMapping("/path/{id}") to #GetMapping("/path-{id}") - everything works. There is no other problems with styles...
I am finding it difficult to retrieve data from a web page when that data was initially passed in from the controller layer.
I am using Thymeleaf 3 and Spring boot v1. I have a webMVC controller which is passing an object to the template. The object looks something like this (pseudo-code):
public class Person{
// Nested object retrieved from various data sources
// and passed to the UI
private Address address;
private Job job;
// Form values I want to retrieve from UI
private String formValue1;
private String formValue2;
// getters/setters
}
My html page is divided into two sections. One section displays most of the Person values, while the other section includes a basic form. When the form is submitted, I want the form values plus ALL original values returned to the server.
What I'm finding is that it seems Thymeleaf will only retrieve values which are in the form, which means I have to stretch the form across both sections of the page, even though the user will only fill out one section of the page. So now the html looks as follows:
<html>
<!--header/body/etc -->
<form th:object="${person}" th:action="#{/person/id}" method="post">
<!-- Form Inputs -->
<input type="text" th:field="${person.formValue1}"/>
<input type="text" th:field="${person.formValue2}"/>
<!-- Values not used in form, but included so they will be sent back
to server -->
<input type="text" th:field="${person.address.city}" readonly="readonly"/>
<input type="text" th:field="${person.address.street}"
readonly="readonly"/>
<input type="text" th:field="${person.job.title}" readonly="readonly"/>
</form>
</html>
Additionally, it seems that Thymeleaf can only retrieve values that have the attribute th:field, but th:field is only assignable to the <input/> element (as far as I know), so any long text I have is truncated to the normal length of an input field, which is rather limited.
So I'm wondering if anyone can help with the following questions:
Can Thymeleaf return values which are not within a form (but returned when the form is submitted)
Is th:field the only option I can use for sending data back? (I've successfully displayed data with th:text, but no luck sending anything back).
Thanks.
Can Thymeleaf return values which are not within a form (but returned when the form is submitted)
This is more about how HTML forms and POST in HTTP works here. HTML form will send whole data within and Thymeleaf will bind that data to an object in your controller. So if you want all the values you should in fact wrap it all in a single form - this is a good way to go. If the case is that you don't want to display all the fields you could use hidden fields.
If you still would like to keep the data in separate forms for some reason you could try to work around it:
By using JavaScript to collect data from both forms and send it
Try to name both forms the same. I am not sure about it but it might work
I wouldn't recommend any of those anyway. Try to keep it simple.
Is th:field the only option I can use for sending data back? (I've successfully displayed data with th:text, but no luck sending anything back)
For a long text you can use textarea.
I need to validate a Promo Code for one of my html Booking form field. If the entered promo code is correct, users can submit the Booking details. Only one unique promo code. Something like "15OFFNOW" How should I do it? Please help.
Thanks.
First, don't put the promo code in your page. Anyone can see it.
I would do this, but it depends on actually functionality.
Do client side check (this can be bypassed by a malicious user)
Do server side check
Do client side check
Use a good non-reversible hashing algorithm and verify what you have in the prom text box to the hash you have stored in a JavaScript variable or in a data-hash attribute.
So if hash(text box value) == valueOf(data-hash), then proceed to sever validation.
Do server side check
In server no need of hash. Just check the post string with the promo code you have.
i try your code
<form method="post">
<input class="form-control form-control-light bdr-2 rd-0" required
data-label="Promo Code"
data-msg="Please enter a valid promo code."
type="text" name="promo-code"
placeholder="Promo Code"
pattern="15OFFNOW" required>
<input type="submit" value="submit"/>
</form>
validation is work . show this message .
You can use Javascript for that , I fyou want to match promocode or you can validate it at backend using any backend language like PHP or java
for JQuery
//previous Ajax code here
if($("#input_id").val() !== "15OFFNOW"){
return false ;
}
// here you can proceed for Ajax request
You are looking for an input pattern, also called regexp (though I would instead suggest doing it js way (but not global) or on server side as advanced users can simply inspect html code). Most probably something like this
<input type="text" name="promo" pattern="15OFFNOW" required >
Also, please try googling it, there're similar questions like this answered also on StackOwerflow, e.g.
html: Can we match an exact string using html pattern attribute only?
js & php: check if input value not equal to integer then don't submit form
I wish to send a long value from my login.jsp page to the struts action from bean as a hidden field. I have done the mapping etc for the two properties username and password and for them the program works fine. Now I want to send a time value as a hidden property named "requesttime" to store the time of login in a table for security check. But I have not been able to figure out how to do it. Here is the part of the jsp page where I am stuck.
<%long time = System.currentTimeMillis();%>
<html:form action="login">
<bean:message key="login.username"/>
<html:text property="username"/><br/>
<bean:message key="login.password"/>
<html:password property="password"/><br/>
<%--I wish to insert "time" as property "requesttime" as hidden here--%>
<html:submit value="login"/>
</html:form><hr/>
<html:errors/>
Please do not mind my ignorance. And thank you for whatever help you may provide.
Using script you can get the time of login. Now do
< input type="hidden" id="time">
and enter the value you got. Using scriplets would be better.
Then in servlet call the request.getParameter("time") and store as a string or as an integer.
Your choice. Hope this helps.....
I started short time ago with JSP, JSTL, HTML and JavaScript so here is my problem:
I need to set the value of a var the value of an input hidden. Other option is if it possible to compare using
<c:if test="....">
the value of a variable that I sent with the request with the value of the hidden input.
Thanks.
Update
I've been trying but can't make it work.
I have this field that contains the id of and object. I also have the list with the objects so what I have to do is find the object related to that ID.
<input type="text" name="id1" />
but if I do this:
<c:set var="dd" value="${param.id1}" />
<input type="text" value="${dd}" />
The input text is empty but the text related to id1 displays 850 (i.e. the value is dinamic)
Any suggestion why is not working?
Update 2
I need the "multipart/form-data" because in the form I need to upload a picture. I understand how to get the parameters from Java, but since I'm not using the server but the JSP pages, there's any way to do it? Just need to read that input element and save it in a variable.
You can access request parameters by implicit ${param} variable.
E.g. http://example.com/context/page.jsp?foo=bar in combination with
<c:if test="${param.foo == 'bar'}">
The foo's param value is bar!
</c:if>
<c:if test="${param.foo != 'bar'}">
The foo's param value is not bar, it is: ${param.foo}
</c:if>
would show the first condition.
If you actually want to retain some hidden input element in subsequent requests (which wasn't really made clear in your question), then all you basically need to do is:
<input type="hidden" name="foo" value="${param.foo}">
Update: as per your update: you need to give the input element a name as well. Thus, e.g.
<input type="text" name="id1" value="${param.id1}" />
This way it's available by request.getParameter("id1") and inherently also ${param.id1}. Do you see it now?
Update 2: as per your comment here: certainly this is related to enctype="multipart/form-data". With this encoding, the request parameters aren't in the parameter map anymore, but instead in the request body, because of the mixup with binary data (file uploads). It's going to be a long story to explain it all, but basically you need to parse the request yourself. If you're on Servlet 2.5 or older, then the Apache Commons FileUpload is very helpful here. Read especially "User Guide" and "Frequently Asked Questions" over there to see code examples and to learn how to use it the right way (also in MSIE!). You can even decide to abstract the FileUpload away so that you can stick using HttpServletRequest#getParameter() and ${param} the usual way, also see this article.
If you're already on Servlet 3.0, then you can just make use of HttpServletRequest#getParts(). You can even abstract it away so that you can stick using HttpServletRequest#getParameter() and ${param} the usual way, also see this article.
Update 3: Oh, you really don't want to use JSP to do all the processing. There it is not for. It's high time to learn Servlet. Besides, when using a Filter which puts all parameters from the request body back in the request parameter map (as described in the both articles), you also don't necessarily need a Servlet after all.
