I have three drop down menus that are chained together. Year, Make Model. I need wordpress search results to show their matching results. If I give them all the name="s" then it only searches the final s= in the url.
I basically need to know how to make
mysite.com/?s=2001&s=Chevrolet&s=Express&Search=Search
turn into:
mysite.com/?s=2001+Chevrolet+Express&Search=Search
or whatever gets the job done.
Any suggestions?
I would not name the selects. Instead, give them ids and make a hidden form field, then use javascript to update the hidden field.
function updateHiddenField(){
var year = document.getElementById("YearDD").value; //this is conceptual
var make = document.getElementById("MakeDD").value; //this is conceptual
var model = document.getElementById("ModelDD").value; //this is conceptual
document.getElementById("s").value = year+"+"+make+"+"+model; //this is conceptual
}
Then later...
<input type="hidden" name="s" id="s" value="">
<select id="YearDD" onChange="updateHiddenField();">
...
Otherwise you could overwrite the "Submit" Button, generate your own query string/url and redirect the page.
Or, in a real dirty way, you could just search the string and convert "&s=" with "+".

I'm trying to make a page with a search function. When you first go to the page, all you have is a search bar. When you type something into the search bar and click the "submit" or "search" button, I want the value in the search box to be submitted to the controller as a string. Then, this value can be used in returning the a model back to the page. Here's what I have so far:
Search.cshtml
#{
ViewBag.Title = "Search";
Layout = "~/Views/Shared/_Layout.cshtml";
}
#ViewBag.PageTitle
<h1>Search All Issues</h1>
<form asp-controller="Report" asp-action="Search" method="get">
<input name="searchstr" id="Search" />
<input type="submit" value="Submit" />
</form>
ReportController.cs
[HttpGet]
public ActionResult Search(string test)
{
ViewBag.PageTitle = test;
var report = _context.Reports.ToList();
return View(report);
}
What am I doing wrong here? For now, it would be nice if I can just get that ViewBag.PageTitle to appear on the page. If I can do that, then I can return the report model just the way I want.
Also, a few additional questions. Some of the stuff I've seen on stack overflow has a recommendation to do a Post in the controller. If I do that, the page errors out. Why is a get needed for this? Intuitively, it makes more sense to me to use a Post...
Turns out I was extremely close; Stephen Muecke had the correct answer. I simply needed to change my input name or parameter name.
I made this mistake as I was considering this from a C++/C standpoint where the parameter names can be irrelevant. I see now, though, that with ASP.NET MVC, you need to have the input name match the parameter name.
Thanks for the help!
My form is dynamic, and submits what the user wants and i have a processing page just to handle the data:
<form id="imageForm" method="post" action="WebFormDesignImageProcessor.aspx" target="imageCollector">
<input id="image61472" name="image[61472]" value="" src="file:\\C:\Users\william.francis\Downloads\errmergerd.jpg" type="file">
<input id="image61474" name="image[61474]" value="" src="file:\\C:\Users\william.francis\Downloads\william_linkedin_photo.jpg" type="file">
<input id="data[image61472]" name="image61472data" value="61472" type="hidden">
<input id="data[image61474]" name="image61474data" value="61474" type="hidden">
</form>
The data is dynamic, and the forms can grow or shrink based on user input. What i was wanting to do is to pair datasets together, and iterate through it in some fashion.
for( i = 0; i < $_POST['data[]'].length; i++){
byte[] img = $_POST['image['.i.']'];
string pk = $_POST['image'.i.'data];
//then query
}
I understand the above sample was in a PHP pseudocode hybrid thing, but was looking for something in ASP.net.
As a sidenote: I can change the name design above to anything as long as the numbers are there... as that is what makes it unique. That may make it a lot easier
edit: I could give the names of the items as idData[] and imgData[], but when sending it to the server, i would not know which item references what.... as there isnt linking.... which is what the numbers are for. This is a hurdle that in part, would help resolve the problem
I don't know if you can quite do the same in .NET; however you could use linq:
var rq = HttpContext.Current.Request;
var keys = rq.Form.AllKeys.Where(i => i.StartsWith("data") == true);
foreach (var key in keys)
{
//check key, and process accordingly
}
Something like that. Note that the name is the identifier available in the form collection, not ID (pretty sure that is the case).
I was reading http://www.orchardproject.net/docs/Creating-1-n-and-n-n-relations.ashx and could not get the idea, if it is possible to easily make master detail editing, to give you concrete example i've attached screenshot from wordpress:
So there is post and post contains set of custom fields, simple 1:N relationship, everything edited in one page - you can add/edit custom field without leaving post page.
May be someone saw similar example for Orchard on internet, or could shortly describe path to achieve this by code, would be really helpful (I hope not only for me, because this is quite common case I think).
This should be possible, although not in the most 'Orchardy' way.
I've not tested any of the below so it is probably full of mistakes - but maybe Bertrand or Pszmyd will be along later today to correct me :-)
As you have probably seen you can pass a view model to a view when creating a content shape in your editor driver:
protected override DriverResult Editor(CatPart part, dynamic shapeHelper)
{
// Driver for our cat editor
var viewModel = new CatViewModel
{
Cats = _catService.GetCats() // Cats is IEnumerable<Cat>
};
return ContentShape("Parts_CatPart_Edit",
() => shapeHelper.EditorTemplate(
TemplateName: "Parts/CatPart",
Model: viewModel,
Prefix: Prefix
));
}
So we can pass in a list of items, and render it in our view like so:
#foreach(var cat in Model.Cats)
{
<span class="cat">
<p>#cat.Name</p>
<a href="...">Delete Cat</p>
</span>
}
The problem here would be posting back changes to update the model. Orchard provides an override of the Editor method to handle the postback when a part is edited, and we can revive the viewmodel we passed in the previous method:
protected override DriverResult Editor(CatPart part, IUpdateModel updater, dynamic shapeHelper)
{
var viewModel = new CatViewModel();
if (updater.TryUpdateModel(viewModel, Prefix, null, null))
{
// Access stuff altered in the Cat view model, we can then update the CatPart with this info if needed.
}
}
This works really well for basic information like strings or integers. But I've never been able to get it working with (and not been sure if it is possible to do this with) dynamic lists which are edited on the client side.
One way around this would be to set up the buttons for the items on the N-end of the 1:N relationship such that they post back to an MVC controller. This controller can then update the model and redirect the client back to the editor they came from, showing the updated version of the record. This would require you to consistently set the HTML ID/Name property of elements you add on the client side so that they can be read when the POST request is made to your controller, or create seperate nested forms that submit directly to the contoller.
So your view might become:
#foreach(var cat in Model.Cats)
{
<form action="/My.Module/MyController/MyAction" method="POST">
<input type="hidden" name="cat-id" value="#cat.Id" />
<span class="cat">
<p>#cat.Name</p>
<input type="submit" name="delete" value="Delete Cat" />
</span>
</form>
}
<form action="/My.Module/MyController/AddItem" method="POST">
<input type="hidden" name="part-id" value="<relevant identifier>" />
<input type="submit" name="add" value="Add Cat" />
</form>
Another possibility would be to create a controller that can return the relevant data as XML/JSON and implement this all on the client side with Javascript.
You may need to do some hacking to get this to work on the editor for new records (think creating a content item vs. creating one) as the content item (and all it's parts) don't exist yet.
I hope this all makes sense, let me know if you have any questions :-)
I have search button on page. user input som data and click search button.
how can search with query string (like google search).
is it correct:
void search_click(...)
{
string item1 = text1.text;
string item2 = text2.text;
Responce.Redirect(currentPage.html?x=item1&y=item2);
}
or has better solution.(c#)
You need to use GET method on your search form.
Probably the easiest way would be not using ASP.NET controls and using plain HTML components instead:
<form method="get" target="search.aspx">
Search: <input type="text" name="q" value="Search"><br>
<input type="submit">
</form>
Then, when the user clicks on Search button, the user will be taken to a place with a URL like:
http://YOUR_SERVER/YOUR_APP/search.aspx?q=hello
Check out the answer to the same question here: How to build a query string for a URL in C#?
You can build a NameValueCollection and output it as the proper format. The top answer has a great example.
Your code has some errors. Use the following:
Responce.Redirect("currentPage.html?x=" + item1 + "&y=" + item2);
I want to pass a query in a hidden filed from 1 page to another by querystring.
Can anyone help me out with the logic?
It's worth taking the time to learn jQuery. It's not very complicated, and it makes writing javascript much easier. There are also many jQuery plugins, such as jquery.url.
Also, as other posters have suggested, you may not wish to put the hidden field's value in the query string if you care about it being displayed to the user. However, if the data is present in a hidden field it will always be possible for a user to find it if they care to look.
If you really do want to put the hidden field in the query string and then extract it via non-jQuery javascript:
hiddenFieldPage.aspx
This form will take the user to processingPage.aspx?datum=someValue when it is submitted. You could probably also just use an ordinary link if nothing else needs to be submitted at the same time.
<form method="GET" action="processingPage.aspx">
<input type="hidden" name="datum" value="someValue">
<input type="submit">
</form>
or, inserting the value from code-behind:
RegisterHiddenField("datum", "someValue");
processingPage.aspx
This script will pop-up an alert box with the value of "datum" from the URL - assuming the form's method is set to "GET":
<script type="text/javascript">
function getUrlParam( key ) {
// Get the query and split it into its constituent params
var query = window.location.search.substring(1);
var params = query.split('&');
// Loop through the params till we find the one we want
for( var i in params ) {
var keyValue = params[i].split('=');
if( key == keyValue[0] ) {
return keyValue[1];
}
}
// Didn't find it, so return null
return null;
}
alert( getUrlParam("datum") );
</script>
If the form's method was set to "POST" (as it usually would be in ASP.NET), then "datum" won't be in the query string and you'll have to place it on the page again:
RegisterHiddenField( "datum", Request.Form["datum"] );
To retrieve the hidden value on the second page:
var datum = document.Form1.item("datum").value;
alert( datum );
You can easily submit a form on one page that points to another page using the action parameter. For instance, inside of page1.aspx put the following:
<form action="page2.aspx" method="GET">
<input type="hidden" name="username" value="joenobody" />
<input type="submit" />
</form>
Since you're using "GET" as the method instead of "POST", you could potentially use Javascript to parse the URL and get the value that was passed. Alternatively, you could use ASPX to store the value of the "username" field somewhere else on the page. I don't know ASPX (or ASP, or anything Microsoft really), but if you can find a way to output something like the following (and are using jQuery), it may do what you require. Honestly though, it sounds like you are going about something all wrong. Can you modify your question to be a bit more specific about what the general object is that you are attempting to accomplish?
<div id="some_div"><%= Request.form("username") %></div>
<script type='text/javascript'>
var value_needed = $('#some_div').html();
</script>
<form method="get">
Assuming you mean hidden in the HTML form sense, your field will be submitted along with all the other fields when the form is submitted. If you are submitting via GET, then your "hidden" field will show up in plain text in the URL. If you don't want the data in the hidden field to be accessible to users, don't put an understandable value in that field.
If you are using aspx, you do not need to parse the query string using JavaScript, or even use <form method="GET" ...>. You can POST the form to the second aspx page, extract the value in C# or VB then write it to a client-side JavaScript variable. Something like this:
page1.aspx:
<form method="POST" action="page2.aspx">
<input type="hidden" name="myHiddenServerField" value="myHiddenServerValue">
<input type="submit">
</form>
page2.aspx:
<script type="text/javascript">
var myHiddenClientValue = '<%= Request.Form['myHiddenServerField']; %>';
</script>
The above would set the client-side JavaScript variable called myHiddenClientValue to a value of 'myHiddenServerValue' after the POST.
This can be a bad idea because if myHiddenServerField contains single quotes or a newline character, then setting it on the client in page2.aspx can fail. Embedding ASP.NET Server Variables in Client JavaScript and Embedding ASP.NET Server Variables in Client JavaScript, Part 2 deals with specifically these issues, and solves them with a server-side class that ensures values being written to the client are escaped correctly.
If you use method="get" on an HTML form then any hidden inputs in that form will be converted to query parameters.
