Is there a way in ColdFusion to change a session variable after a page change? - Especially after a page change to a specific page?
Goes to one page --> change session variable
Goes to a different page --> change session variable to something else
Can you add code to the existing page? When importantpage.cfm is loaded you could run this at the top of the page
<cfset session.variable = 'important page loaded'>
That should accomplish what you are looking for.
You could also add <cfset> tags to your application.cfm/cfc file
You can manage this in application.cfm or application.cfc and then this will carry over to every page and subfolder in your application. You would just do an if statement using the CGI variable for the name of the page.
<cfscript>
if (findnocase("page1",cgi.script_name)) {
session.myVar="Variable State 1";
} else if (findnocase("page2",cgi.script_name)) {
session.myVar="Variable State 2";
} else {
session.myVar="Variable State DEFAULT";
}
</cfscript>

I have written a Joomla component which is working well. I now want to add a button to an admin list view that when clicked automatically starts a CSV download of only the items selected in the list.
I'm OK with the model logic, the problem I've got is passing the selected cids or presenting raw output without the template.
If I use JToolBar's appendButton function to add a 'Link' type button, then I can send the user to a URL with 'format=raw', but I can't send information about which items were checked.
If I use JToolBarHelper::custom to add a custom list button, then I can send the information about which buttons were checked, but I can't send format=raw
As far as I can see there are two solutions, but I don't know how to implement either of them. Option one would be to force templateless raw output without a URL parameter of format=raw. Option two would be to set a hidden variable with format=raw in the admin form.
Any help would be appreciated
I've solved this as follows:
I added this hidden field to the admin form
<input type="hidden" name="format" value="html" />
Then subclassed JToolbarButtonStandard overriding the _getCommand with
protected function _getCommand($name,$task,$list)
{
JHtml::_('behavior.framework');
$message = JText::_('JLIB_HTML_PLEASE_MAKE_A_SELECTION_FROM_THE_LIST');
$message = addslashes($message);
if ($list)
{
$cmd = "if (document.adminForm.boxchecked.value==0){alert('$message');}else{document.getElementById('adminForm').format.value='raw'; Joomla.submitbutton('$task')}";
}
else
{
$cmd = "document.getElementById('adminForm').format.value='raw'; Joomla.submitbutton('$task')";
}
return $cmd;
}
So that when the button was clicked it changed the format parameter from html to raw.
I'm not going to mark this as solved in case anyone has any better ideas
I am using code like this to detect the browser and apply a condition to display or not display <label>:
#{
var settings = Model.PartFieldDefinition.Settings.GetModel();
System.Web.HttpBrowserCapabilitiesBase theBrow = Request.Browser;
}
<fieldset>
#{
if ((theBrow.Browser == "IE") && (theBrow.MajorVersion < 10))
{
#:<label>#Model.DisplayName</label>
#://Some Code for inputs
}
else
{
#://Some Code for inputs
}
}
</fieldset>
I have been trying to figure out if I can (and if so, how) I could utilize this logic to detect what path in the website the user is in to display or not display <label>
For example, on any other path I want the label displayed. However, for the pages under ~/Services (the path), I want to be able to hide the label.
It's a little bit more complicated than that. The code is in an editor template that gets used all over the site. If I use CSS in the editor template to "hide" the label I will affect all the pages. I was hoping with the above logic I can avoid that and only apply my logic on certain pages under a path.
Thanks.
Update
I have tried the following:
#{
string CurrentURL = Request.ApplicationPath;
}
<fieldset>
#{
if ((CurrentURL == "Services")) // also tried "/Services"
// rest of code left out for brevity
}
but the labels are hidden on all pages, even outside the path "~/Services". Am stuck on the syntax.
Found answer
I did the following:
#{
string CurrentURL = Request.Url.AbsoluteUri;
}
<fieldset>
#{
if (CurrentURL.Contains("Services"))
}
and it worked. I don't know if anyone can comment, but which would be better to use: Request.Url.AbsoluteUri or Request.Url.ToString() (both of which work)?
I just try to prevent re submission problem when refresh form page. so I use session flashdata() method and redirect same form page. but I want also display recent inputed data on form VIEW page. then I am try $this->db->insert_id() on my form VIEW page . but it always show 0. how can I solve it?
when you redirect the user after the successful form submission then add the parameter in the url just a exapmle with dummy code to make an idea for you
$insertedid=$this->my_model->add_info();
//your add_info() should return the inserted id
redirect("/myformcontroller/myformpage/".$this->db->insert_id());// add id in redirect url
on your myformcontroller controller's myformpage function
function myformpage() {
$insertedid=$this->url->segment(3);
if(!empty($insertedid)){
//get new added information and pass it to view
}
// your other code
}
hope it makes sense
I done project in ASP.net MVC3. In my project i create a session as follows in Home Controller
if (Session["ulclass"] == null)
{
Session["ulclass"] = "list";
}
I use this session to my Product List page.. as a class for div tag as follows..
<div id="listheading" class="listHead" #if (Session["ulclass"].ToString() == "grid")
{
<text>style = "display:none;";</text>
}>
When i copy this Productlist URL from FireFox to Chrome...
session value not come.. it produce the error...
Can any one help this ?
You can use cookieless sessions. That way the session id is sent in the URL instead of a cookie, so then you could just copy the URL anywhere and you are still in the same session.
Put this in web.config:
<sessionState cookieless="true" />
(The drawback is of course that anyone can copy the URL anywhere and still be in your session...)
More about cookieless session: http://msdn.microsoft.com/en-us/library/aa479314.aspx
Use Convert.ToString(Session["ulclass"]) == "grid" to avoid error first, and then add in we.config
I have a form on a web page, with one field to enter a code, to search for a property.
On clicking 'submit' I want to be able to run a script in the background without leaving the page.
The script will need to run a MYSQL statement which will have one of these results:
The property code does not exist, so display a Javascript Alert saying it does not exist.
The property is for sale, so call an existing javscript function 'saleSubmit(propertyCode)' to overwrite the exsiting web page with a new page sale.php for that property code
The property is for rent, so call an existing javscript function 'rentSubmit(propertyCode)' to overwrite the exsiting web page with a new page rent.php for that property code
The property is for sale and rent, so display 2 checkboxes within a div on the page to choose either the sales details or the rental details.
Can anybody point me in the right direction here?
Hi Nick - I think I screwed the system up a bit as I initially posted a question, then created an account which would not let me comment on the thread.
The status of the query is as simple as: does not exist, sale, rent, sale & rent
Extra advice would be really appreciated as I am problems googling for examples or a tutorial to point me in the right direction.
I first took this approach when I was looking at this problem to check that the form and Select statement were working correctly. So my form code looked like this:
<form name="idsearch" action="" method="post" onsubmit="xmlhttpPostForm('includes/idsearch-response.php', 'idsearch', 'idSearchResult', '<img src=\'images/loading.gif\'>'); return false;">
<input type="text" id="idRefNo" name="idRefNo" value="Enter Property Code" onfocus="this.value='';" />
GO <input type="image" src="img/template/search2.gif" alt="Click to Search for Properties"/>
and the php code called looked like this:
$idRefNo = $_POST['idRefNo'];
$query = "SELECT DISTINCT * FROM property WHERE property.Title = '".$idRefNo."' AND suspend != 'Yes'"; $result = #mysql_query ($query);
if ($result) { // If the query runs ok
if ($result != "") {
while ($row = mysql_fetch_array ($result, MYSQL_ASSOC)) {
if ($row["BaseRental"] > 0 AND $row["Saleprice"] > 0) {
echo 'This property is for RENT and for SALE <br/>';
} else if ($row["BaseRental"] > 0) {
echo 'This property is for RENT only <br/>';
} else if ($row["Saleprice"] > 0) {
echo 'This property is for SALE only <br/>';
} else {
echo 'DOH! What is going on here!!! <br/>';
}
}
As I said above I would appreciate it if you could point me in the right direction to achieve what I want to do at the beginning of this thread.
First of all let's differentiate between the page(client) and your mysql database(server). Your page will have to send some request to your server which triggers a script to query the database. The result of that query is returned as a response to your page.
You could send a request by using javascript and the xmlhttprequest or try jquery which offers very simple methods to make requests ($.ajax(...)).
Your server and the script which queries your db should then return some meaningful status back to your client which has to interprete the result: Doing alerts, showing your div or whatever you'd like to do. I suggest returning the response as json which can be directly used in javascript without any parsing hassle. If the status of your query as simple as: does not exist, sale, rent, sale & rent. You could go as far and encode those as plaintext numbers, no json needed.
