I have a form that will send an array of data to an ASP page.
Let's say this array is called "matrix".
Usually, on the ASP receiving the form, I will write this out to retrieve the form inputs from the array "matrix".
Request.Form("matrix[]")(i) where i = 1, 2, 3 which are the elements in the array.
Let's say I want to do make a variable like this
a="matrix"
and I want to use this variable a and put it into the request form, instead of writing "matrix", so that it would look something like this
Request.Form(a[])(i)
How can it be done? For now, all my attempts are showing blank. e.g. when I try to make them appear on the page with response.write, nothing shows up.
Please help me or let me know if it cannot be done, I've been spending hours on this.
Request.Form("matrix[]") is taking a string value of "matrix[]" not an array of strings called "matrix".
So you need to do either
a = "matrix[]"
Request.Form(a)(i)
or
a = "matrix"
Request.Form(a & "[]")(i)
Unlike PHP which requires adding square brackets, in classic ASP you just have to give the same name to the elements you want to be combined into an array.
The HTML should be:
<input type="text" name="matrix" />
<input type="text" name="matrix" />
<input type="text" name="matrix" />
Then you can iterate over the submitted values like this:
For x=1 To Request.Form("matrix").Count
Response.Write("Value of matrix #" & CStr(x) & "is: " & Request.Form("matrix").Item(x))
Next
Note that all elements are included, even if user left them empty.

<input type="text" value="Phone" name="Phone" />
I can't set using Id as like below. I dont have rights to change the tag as well. Is ther any option using name value inorder to set value?
Set Helem=IE.document.getElementByValue("Phone")
Helem.Value = "1234565678"
Assuming IE in your sample is some instance of internet explorer or Shell.Application, use the following sintax
Set Helem = IE.document.getElementsByName("Phone")
And it will not return a reference to the element, but a HTMLCollection of elements. From your code, it can be, more or less, handled as as array. Assuming there is only one element with that name, reference to it will be in Helem(0)
I have a form with many input elements inside that looks like:
<form>
<input name="foo[abc]" />
<input name="foo[def]" />
...
</form>
(foo should be a array inside $_POST)
How can I send these values trough AJAX, without having to manually enter each value in the data parameter?
use:
var data=$(your_form).serialize();
and send this data using ajax.
it'll automatically convert all array like inputs and normal to a string like get method..
$("form").serialize();
Use the serialize function; see an example here (it's a $.post(), but same difference).
hi i am using codeigniter . i have a form , there i add hidden fields dynamically . so every hidden field is <input type='hidden' name='hidden' value="+$(this).attr('title')+"> so the name is equal .
the problem is when i submit the form and try to get my hiden field values i can only get one hidden field value , because the names are same
i print my form values
print_r($this->input->post());
i have 2 hidden fields but i get only one
Array
(
[hidden] => march
[textbox] => march
[mysubmit] => Submit
)
i can change the name dynamically of hidden field when creating , but then i don't know exactly the name of my hidden field ,
how can i get hidden field values with same name ?? is there any way to get form values other than by name ?? i tried and can not find an answer , please help .............
You'll need to use brackets in your name attributes:
<input type='hidden' name='hidden[]'>
<!-- ^^^^ -->
This will allow PHP to accept multiple inputs with the same name as an array of values, so in this case, $_POST['hidden'] will return an array of strings.
By default they are indexed starting at 0, so $_POST['hidden'][0] will get you the first one, $_POST['hidden'][1] will get you the second, etc., however - you can explicitly index them if it's easier for you, either with numbers or strings.
<input type='hidden' name='hidden[first]'>
<input type='hidden' name='hidden[second]'>
Or:
<input type='hidden' name='hidden[0]'>
<input type='hidden' name='hidden[1]'>
You can nest these as deep as you want like hidden[first][1][], and they will be treated similarly to a PHP array when you get the $_POST values, but you need the brackets in the HTML.
Without brackets, only the last field's value will be available in the $_POST array. This is a PHP feature, Codeigniter can't do anything about it.
I want to restrict entry of input onto a field of type number such that input cannot be outside range of min-max specified in the html.
input type = "number" min = "1" max = "5"
Is there a way of outputting the number field without the text box and i would rather not use
"input type = range"
as slider does not show value currently selected
Please help.
Thanks.
Based on what you said, I suggest using a simple input text field and check it's value validity on submission via JavaScript (as #Kush mentions above). You could also check it as the user types, or moves focus away from that field.
<form>
Only 1 to 100 <input type="text" name="number" pattern="\d{1,2}(?!\d)|100" title="one to hundreed only">
<input type="submit">
</form>
I am trying to create a form that allows the editing of multiple rows of data. I have no problem looping through and getting input boxes to render...I just cannot get the name attributes to output correctly.
I know that in order to submit a collection you need to post back an indexed name where the index is sequential starting at 0.
<input name="Books[0].Title" />
<input name="Books[1].Title" />
and so on...
Now, I can get the EditorFor function to output my proper name with given the following loop code
#For n = 0 To (Model.Books.Count - 1)
#Html.EditorFor(Function(m) Model.Books.Item(n).Title)
Next
giving me
<input name="Books[0].Title" />
<input name="Books[1].Title" />
and so on...
My problem is VS shows the following warning
Using the iteration variable in a lambda expression may have unexpected results. Instead, create a local variable within the loop and assign it the value of the iteration variable.
Yet when I change the loop to
#For n = 0 To (Model.Books.Count - 1)
Dim item = Mode.Books.Item(n)
#Html.EditorFor(Function(m) item.Title)
Next
I get
<input name="$VB$Local_item.Title" />
<input name="$VB$Local_item.Title" />
and so on...
Any thoughts? Should I just ignore the warning?
Thanks.

MVC works by actually breaking apart the lambda expression, and seeing what it's made of. It doesn't just execute the lambda and get the result. So you need to actually use the model parameter in the lambda for it to work. This should do it for you:
#For n = 0 To (Model.Books.Count - 1)
Dim index = n
#Html.EditorFor(Function(m) m(index).Title)
Next
