The app I am working on has hidden input variables set on initial load of the page. The variables need to be accessed across all pages. The reason for not converting these to session variables is the user can open another browser with different parameters and passing those value as hidden inputs make it work without any issue. What is the best possible alternative so as to get rid of these hidden inputs..I tried converting all variables into a Structure, but again the structure needs to be posted as part of form submission to make it available to subsequent pages.Another disadvantage of this app is use of frames.I don't have any code to post.
It sounds as if you want different browsers instances which are associated with the same web session to maintain their own distinct sets of data. Doing this by passing form or url variables around seems like a bad idea.
One approach that you could use would be, onSessionStart (or as required), create a structure in the users session to hold instances of the data. For example
session.data = {
someRandomKey: {
valueA: 42,
valueB: "Porridge"
}
}
Then just pass someRandomKey as a hidden form field or querystring parameter. Now, when they submit the form to update variables you use the id from the hidden form field to find the appropriate structure from session.data.
When the user needs a new instance of this form, give them some way, like a link or button, that creates a new unique key, inserts a struct in session.data with this key and populates it with whatever defaults are needed then loads the form passing along the new id as a hidden form field or querystring param again.

So I have a dynamic table in angular where im passing data in, then creating the table. I want to add some CSS in order to check the values then add some styling onto it. So if the value is a minus number, then display the data in red
I have used attribute data to check the actual data, which works fine until i call to typescript method to generate the data instead of hardcoding the data in, and this is where is goes wrong. So I want to call this method to get the data instead, and it just displays the method name instead of the method return
You can use the attribute binding of data instead of the interpolation if the data returned by the method is not a string - more details here
[attr.data]="getData(header, body)"
I have a HTML multiple select being used which caused no issue until a selection with a comma was entered. When saving / loading the values are split by ',' into a list. Therefore causing an issue
I have tried to find a way of possibly changing the character that is being used to split the values when the form is posted but came to a dead end.
Would be very grateful if someone has any insight into this.
Thanks in advance.
---Update with Code---
The control is created dynamically
Dim SelectName1 As New HtmlSelect
SelectName1.ID = "SelectName" & id
SelectName1.Name = "SelectName"
SelectName1.Multiple = True
and filled by looping though the values.
For Each value As String In Request.Form(idToFind).Split(",")
If Not IsDBNull(SelectName.Items.FindByValue(value)) Then....
I cannot add any more code than that, Apologies
After updating the question by add code, I think the available options are limited:
Create an extra Javascript method, that stores the selected values in a json object and store it into a hidden input field. I'm not an expert in asp.net, though I'm sure there exists a method to parse json objects from a string.
Create an extra javascript method, that concatinating all values to a String and store it into a hidden input field. With creation of a single string, you can define your own delimiter.
After that, add this extra Javascript mehod to the event onSubmit. Then submit the form and read the value from hidden input field.
P.S. In my eyes the second idea is more simple to create, than the first one. And maybe there are better ways.
I've two fields with the same name name="s[]", but this creates an array, I don't need an array instead I'd like to construct a string.
I'm using these fields to submit search query to wordpress, if I will use an array I will have to mess with wordpress core, which I don't want. So my only option is to create 1 single string from two fields and submit it to query.
What do you think?
I think there are two options:
Submit the form to a different page, which redirects to the normal WordPress search page
Catch the onSubmit event using JavaScript and rewrite / add to the form data
I would prefer option 1 because it will work for browsers that don't use JavaScript. If you go with option 2, then you should not even show your two-field search interface to browsers that don't have JavaScript.
I have created Wordpress custom fields through functions.php. My code works fine, and I've few input fields and some checkboxes.
Problem is when I save post, even if I don't put content inside my form, these rows are created in DB. I'd like to do some kind of php check and avoid creation of row in DB if field content is not saved.
I tried several ways, but in most cases it would result in incorrect behaviors of checkboxes for example.
Full code is here: http://pastebin.com/embed_js.php?i=Vvnseiep
I'd appreciate your help in this matter. I'm not very experienced.
Thanks!
Here Validation part comes into play. Why cant you use Javascript to validate your input in the client environment itself and then allowing it to hit the db.
Name all of the checkboxes the same(name="meta_box_check[]"). They must still have different ID's. When the form is posted you will be given an array of values that were checked in $_POST['meta_box_check']. You can then check if the array is empty. You can also save the checkbox data as JSON data. This isn't always good practice, but will only use one data row to save any and all checkbox values.
<?php
if(!empty($_POST['meta_box_check']))
{
//process your data and save it
update_post_meta($post_id, 'meta_features_checklist', json_encode($_POST['meta_box_check']));
}
?>
This is a basic example and make sure you do some data validating before saving.
So how can I pass a value from one form to another? For example: The user select's an organization from a list and this opens up a trip form that allows a user to enter various information regarding the trip. At one place I would like to add another little pop up form where they can enter contact information (just a name and phone for POC) of the organization they are visiting.
So when that initial form opened from the selection screen it has two IDs that are simply hidden in text boxes (one being the tripID, and the other being the OrgID), so how do I pass these to the second little pop up form so that the contact information has the relative IDs with it.
Thanks.
The best approach in these cases is not to attempted to pass a bunch of variables. It is too much code, and is inflexible. For example, if you need to pass two values, what happens over the years when that requirement grows to 5 values? Trying to maintain and pass a whole whack of values is too much coding work.
Keep in mind that each form in ms-access is really a class object that you can manipulate in code. So, use a object approach here and you find you not only write less code, but your code will be more clean, more modular, no need for global vars, and code you write can often be re-used between different forms.
Here is how:
In general when one form launches another form in the 2nd form in the forms on-open event (in fact, you can even use as late as the on-load event) you can pick up a reference to the PREVIOUS form object. In other words, you can use a object approach here.
At the forms module level, for form I declare a form object as:
Option Compare Database
Option Explicit
dim frmPrevious as form
Then, in the forms on-load event, we go:
Set frmPrevious = Screen.ActiveForm
Now, any code in our form can FREELY use code, events, even varibles declared as public from that previous form in code.
So, if you want to force a disk write of the previous form, and re-load of data.
frmPrevious.Refresh
If you want to set the ID value, then go:
frmPrevious!ID = some value
And, note that you can even declare form previous as a PUBLIC variable for that form, and thus if you two forms deep, you could go:
frmPrevious.frmPrevious!ID = some value
So, simply declare a forms object in EACH forms code module (or at lest the ones where you need to use values in code). The above means any code has a ready made reference to the previous form object. Functions declared as public in a form will become a METHOD of the form, and can be run like:
frmPrevious.MyCustomRefresh
or even things like some option to force the previous form to generate and setup a invoice number:
frmPrevous.SetInvoice
or
frmPrevious.SetProjectStatusOn
So not only can you shuffle values and data back and forth, but you can easily execute features and functions that you build in code for the prevous form.
In fact as a coding standard, MOST of my forms have a public function called MyRefresh.
Note that the beauty of this approach is that you can thus read + use + set values from that previous form. This allows your code to not only receive values, but also set values in that previous form. So this approach is bi-directional. You can shuffle data and values back and forth between the forms. The other advantage here is you NOT restricted to just variables, but can use fields, control values (events, properties) etc.
This approach means that much of the previous form is now at your fingertips.
So don’t try to pass a whole whack of variables. Pass a reference to the form and you have a nice ready made object at your fingertips and it makes this type of coding problem a breeze.
The usual way would be to reference the textboxes in the initial form from the popup form, like this:
Forms!frmInitialForm!tripID
Forms!frmInitialForm!OrgID
However, this tightly binds the popup form to the initial form, so that it cannot be used anywhere else in the application.
A better approach is to use OpenArgs:
DoCmd.OpenForm "frmPopup", OpenArgs:=Me.tripID & ", " & me.OrgID
This places your two values into a string, which is passed to the popup form. You can then parse the two values out of the OpenArgs using the Split function.
