My URL is:
location=Berlin&location=Georgia&location=Kopenhagen
This URL is generated from the following form:
<form action="/posts" method="get">
<input name="location" value="Berlin" type="checkbox">
<input name="location" value="Georgia" type="checkbox">
<input name="location" value="Kopenhagen" type="checkbox">
<button type="submit">Search</button>
</form>
My Controller is params[:location]
Output:
Kopenhagen #=> I need all like: Berlin,Georgia,Kopenhagen
How can I show all examples like above?
I think it's better to do like this in the html(view).
<form action="/posts" method="get">
<input name="location[]" value="Berlin" type="checkbox">
<input name="location[]" value="Georgia" type="checkbox">
<input name="location[]" value="Kopenhagen" type="checkbox">
<button type="submit">Search</button>
</form>
Then, in the Controller, you can get location like this.
location = params[:location] // as array
or
location = params[:location].join(',') // as string
try this location=Berlin,Georgia,Kopenhagen and in controller you will got
params[:location]= "Berlin,Georgia,Kopenhagen"
and you can convert it in array if you want
params[:location]= "Berlin,Georgia,Kopenhagen".join(',')
location=Berlin&location=Georgia&location=Kopenhagen
I don't think this is valid URL. You can change your form to
<form action="/posts" method="get">
<input name="location1" value="Berlin" type="checkbox">
<input name="location2" value="Georgia" type="checkbox">
<input name="location3" value="Kopenhagen" type="checkbox">
<button type="submit">Search</button>
</form>
Then you can access the params[:location1], params[:location2] and params[:location3] seperately

I have just added search box to an index view
<form asp-action="Index" asp-route-account="#Model.First().AccountId" method="get">
<div class="form-actions ">
<p>
<input id="searchStringId" type="text" name="searchString" value="#ViewData["currentFilter"]" />
<input type="submit" value="Search" class="btn btn-primary">
<a asp-action="Index" asp-route-account="#Model.First().AccountId">Back to Full List</a>
</p>
</div>
</form>
This gives me:
https://localhost:44377/MainUsers/Funds?searchString=aldi
But I need
https://localhost:44377/MainUsers/Funds?account=1&&searchString=aldi In other words I need the search string to also include the route id.
Any ideas?
I need the search string to also include the route id. Any ideas?
You can try to achieve the requirement by using a hidden input field as below.
<input name="account" type="hidden" value="#Model.First().AccountId" />
<input id="searchStringId" type="text" name="searchString" value="#ViewData["currentFilter"]" />

I have form and inside I have radio button option , I have the controller class and the model. I can successfully save the other data but radio buttons options reflects to database as 0 always. I believe there is something wrong with thymeleaf radio button implementation.
<form id="add" role="form" th:action="#{/add}" method="post" th:object="${radiobutton}">
<input type="hidden" th:field="*{id}"/>
<div class="form-group">
<label>is it new</label>
<label class="radio-inline">
<input type="radio" name="optionsRadiosInline1" id="optionsRadiosInline1"
value="true" th:checked="*{isNew}"/>Yes
</label>
<label class="radio-inline">
<input type="radio" name="optionsRadiosInline1" id="optionsRadiosInline2"
value="false" th:checked="*{isNew} == false"/>No
</label>
</div>
</form>
I found it , values should be 0 or 1 instead of true and false
<form id="add" role="form" th:action="#{/add}" method="post" th:object="${radiobutton}">
<input type="hidden" th:field="*{id}"/>
<div class="form-group">
<label>is it new</label>
<label class="radio-inline">
<input type="radio" name="optionsRadiosInline1" id="optionsRadiosInline1" value="1"
th:checked="*{isNew}"/>Yes
</label>
<label class="radio-inline">
<input type="radio" name="optionsRadiosInline1" id="optionsRadiosInline2" value="0"
th:checked="*{isNew} == false"/>No
</label>
</div>
</form>
When I submit the following form
<form name="fileUpload" id="fileUpload" method="post" action="javascript:void(0);" enctype="multipart/form-data">
<input id='id' type=text name='id' value='H123'>
<div class="file_browser">
<input type="file" name="multiple_files[]" id="_multiple_files" class="hide_broswe" multiple />
</div>
<div class="file_upload">
<input type="submit" value="Upload" class="upload_button" />
</div>
</form>
The files[] get uploaded OK but input "#id" is not in the $_POST array.
I need it because I want to pass the name of the directory that the images are to be stored in.
I notice that you are missing quotation marks around 'text' in
<input id='id' type=text name='id' value='H123'>
Which should be:
<input id='id' type='text' name='id' value='H123'>
Besides that I can't see any obvious reason why it shouldn't work.
I am trying to get username and password from the textfield. This is the HTML code:
<form class="navbar-form pull-left">
<input type="text" class="span2">
<input type="text" class="span2">
<button type="submit" class="btn">Submit</button>
</form>
How can I get this username & password in the LoginController to check for authentication?
First, you need to add a name property to your input fields. Then specify the action and method attributes for the form. The form would look like this then:
<form action="your_route_goes_here" method="post" class="navbar-form pull-left">
<input name="username" type="text" class="span2">
<input name="password" type="password" class="span2">
<button type="submit" class="btn">Submit</button>
</form>
In your LoginController, you can then access the username and password like so, respectively:
params[:username]
params[:password]
I have the following code in my HTML.erb
<form>
<input id="do" type="hidden" value="0" />
<button type="submit" value="Next">SUBTRACT</button>
</form>
<form>
<input id="do" type="hidden" value="1" />
<button type="submit" value="Next" >ADD</button>
</form>
Now When I click the any of the 2 buttons, I want to check the value of the input id="do" inside my Ruby Controller. What would the syntax look like ?
This should optimally be separated into two actions in the controller where each of the forms would submit (using the action attribute).
<form action='add'>
<input id="do" type="hidden" value="0" />
<button type="submit" value="Next">SUBTRACT</button>
</form>
<form action='subtract'>
<input id="do" type="hidden" value="1" />
<button type="submit" value="Next" >ADD</button>
</form>
#in your controller
def add
# do the addition processing
end
def subtract
# do the subtraction processing
end
If you really need to implement them in 1 action, then you could use Rails params object.
You need to set the name attributes, the name attributes get sent to the controller in the params hash
<form>
<input id="do" name="subtract" type="hidden" value="0" />
<button type="submit" value="Next">SUBTRACT</button>
</form>
<form>
<input id="do" name="add" type="hidden" value="1" />
<button type="submit" value="Next" >ADD</button>
</form>
In the controller,
the params[:subtract] or params[:add] will have the value depending on subtract clicked or add clicked .
