  • PHP error problem.

    - by TaG

  • sql: trying to select the second biggest element but selects the biggest

    - by matthy
    we want to have the second biggest element. We first use ANY to exclude the biggest one. Then we use all to select the biggest. However when we run this query, it shows the biggest and not the second one. Why? SELECT * FROM bestelling WHERE totaalprijs > ALL ( SELECT totaalprijs FROM bestelling WHERE totaalprijs < ANY ( SELECT totaalprijs FROM bestelling ) ) elements in the table: 157.00 5.00 82.80 15.00 20.00 20.00

  • How do I grab and use a variables coming back through ValueList from an AJAX call?

    - by Mel
    I'm trying the following code to execute a search and it's not working. On the search.cfm page, the only value coming back is the value I input into the search field (even if I click an autosuggest value, it's not coming back; only the letters I actually type myself come back). <cfform class="titleSearchForm" id="searchForm" action="search.cfm?GameID=#cfautosuggestvalue.GameID#" method="post"> <fieldset> <cfinput type="text" class="titleSearchField" name="TitleName" onChange="form.submit()" autosuggest="cfc:gz.cfcomp.search.AutoSuggestSearch({cfautosuggestvalue})"> <input type="button" class="titleSearchButton" value=" " /> </fieldset> </cfform> Query in CFC: <cfquery name="SearchResult" datasource="myDSN"> SELECT CONCAT(titles.TitleName, ' on ', platforms.PlatformAbbreviation) AS sResult, games.GameID FROM games Inner Join platforms ON games.PlatformID = platforms.PlatformID Inner Join titles ON titles.TitleID = games.TitleID WHERE UCase(titleName) LIKE Ucase('#ARGUMENTS.SearchString#%') ORDER BY titleName ASC; </cfquery> Two things: First of all, I would like to get the GameID back to the page making the AJAX request; I know why it is not coming back: Because I'm only returning sResult var, which does not include the GameID. Is there a way to return the GameID value without displaying it? The second thing: How to I grab a value from the auto-suggest once it is returned? Say I want to grab the GameID, or if I can't do that, the "TitleName" to use that in my query? I tried passing it to the form this way: action="search.cfm?GameID=#cfautosuggestvalue.GameID#" - but that does not work. How do I reference the autosuggestionvalue varaibles for use? Thanks

  • Get index values for an array to print in value attribute for radio buttons

    - by kexxcream
    Problem: To get the index values of an array to print accordingly in value attribute of radio buttons. The array $_SESSION['items']: Array ( [2] => Array ( [category] => 2 [question] => Array ( [6] => Källorna refereras separat [7] => Vissa försök till sammanbindning [8] => En del sammanfattningar [9] => Olika forskningslinjer jämförs och sammanfattas [10] => Kontraster, jämförelser, sammanfattningar; centrala likheter och skillnader framhävs ) [title] => Integration av källorna ) ) I have a PHP function that looks like this: function itemsLayout ($array) { for ($i = 1; $i <= count($array['question']); $i++) { $form .= '<input type="radio" name="'.$array['category'].'" id="'.$array['category'].'" value="INDEX VALUE FOR QUESTION ARRAY HERE">'; } return $form; } PHP code: I get the index by using the following: $key = key($_SESSION['items']); $current = $_SESSION['items'][$key]; And I print the first index by using: echo itemsLayout($current); Question: How do I get the index values 6, 7, 8, 9, 10 to print in the value attribute for each radio button?

  • Losing URI segments when paginating with CodeIgniter

    - by Danny Herran
    I have a /payments interface where the user should be able to filter via price range, bank, and other stuff. Those filters are standard select boxes. When I submit the filter form, all the post data goes to another method called payments/search. That method performs the validation, saves the post values into a session flashdata and redirects the user back to /payments passing the flashdata name via URL. So my standard pagination links with no filters are exactly like this: payments/index/20/ payments/index/40/ payments/index/60/ And if you submit the filter form, the returning URL is: payments/index/0/b48c7cbd5489129a337b0a24f830fd93 This works just great. If I change the zero for something else, it paginates just fine. The only issue however is that the << 1 2 3 4 page links wont keep the hash after the pagination offset. CodeIgniter is generating the page links ignoring that additional uri segment. My uri_segment config is already set to 3: $config['uri_segment'] = 3; I cannot set the page offset to 4 because that hash may or may not exists. Any ideas of how can I solve this? Is it mandatory for CI to have the offset as the last segment in the uri? Maybe I am trying an incorrect approach, so I am all ears. Thank you folks.

  • Struggling with ASP.NET MVC auto-scaffolder template

    - by DanM
    I'm trying to write an auto-scaffolder template for Index views. I'd like to be able to pass in a collection of models or view-models (e.g., IQueryable<MyViewModel>) and get back an HTML table that uses the DisplayName attribute for the headings (th elements) and Html.Display(propertyName) for the cells (td elements). Each row should correspond to one item in the collection. Here's what I have so far: <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl" %> <% var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; // How do I make this generic? var properties = items.First().GetMetadata().Properties .Where(pm => pm.ShowForDisplay && !ViewData.TemplateInfo.Visited(pm)); %> <table> <tr> <% foreach(var property in properties) { %> <th> <%= property.DisplayName %> </th> <% } %> </tr> <% foreach(var item in items) { HtmlHelper itemHtml = ????; // What should I put in place of "????"? %> <tr> <% foreach(var property in properties) { %> <td> <%= itemHtml.Display(property.DisplayName) %> </td> <% } %> </tr> <% } %> </table> Two problems with this: I'd like it to be generic. So, I'd like to replace var items = (IQueryable<TestProj.ViewModels.TestViewModel>)Model; with var items = (IQueryable<T>)Model; or something to that effect. A property Html is automatically created for me when the view is created, but this HtmlHelper applies to the whole collection. I need to somehow create an itemHtml object that applies just to the current item in the foreach loop. I'm not sure how to do this, however, because the constructors for HtmlHelper don't take a Model object. How do I solve these two problems?

  • HTML: Menus as UL instead of DIVs?

    - by JamesBrownIsDead
    I recently created a menu for a web page where buttons are DIV elements. I've been Googling around and see that many people create UL lists and each button is a LI element. What benefit is using an UL and LIs instead of just DIVs? Is it somehow better for SEO? Does this have to do with "semantic" markup? Any compelling reason to rewrite my menu as a UL?

  • C/C++ Control Structure Limitations?

    - by STingRaySC
    I have heard of a limitation in VC++ (not sure which version) on the number of nested if statements (somewhere in the ballpark of 300). The code was of the form: if (a) ... else if (b) ... else if (c) ... ... I was surprised to find out there is a limit to this sort of thing, and that the limit is so small. I'm not looking for comments about coding practice and why to avoid this sort of thing altogether. Here's a list of things that I'd imagine could have some limitation: Number of functions in a scope (global, class, or namespace). Number of expressions in a single statement (e.g., compound conditionals). Number of cases in a switch. Number of parameters to a function. Number of classes in a single hierarchy (either inheritance or containment). What other control structures/language features have limits such as this? Do the language standards say anything about these limits (perhaps minimum requirements for an implementation)? Has anyone run into a particular language limitation like this with a particular compiler/implementation? EDIT: Please note that the above form of if statements is indeed "nested." It is equivalent to: if (a) { //... } else { if (b) { //... } else { if (c) { //... } else { //... } } }

  • ASP.net MVC 2 SPARK - Create "Add New Item" link in spark page.

    - by KarlBear
    I have a web form in SPARK which allow the editing of a Facility class that contains Rooms. When editing the Facility all the Rooms are listed for editing too. The form works fine for editing, but I would like to include a button "Add Room" that adds a new blank room below the existing ones. Any idea how this is accomplished? Currently I am doing this in my SPARK page: [All the Facility editing stuff...] <p>Room</p> <div class="small">Enter the rooms associated with this facility.</div> <div class="add"> <div id="room"> <AddFacilityRoom each="var roomModel in Model.FacilityRooms" RoomModel="roomModel" Index="roomModelIndex" /> </div> <a id="addRoom" class="add" href="events/room/add.mvc">Add a room</a> </div> AddFacilityRoom contains the html elements for editing a room. I would like add.mvc to create a new empty Room class and inject a new identical (but empty) control below the existing ones. Currently, though it opens a new page when the "Add a Room" button is clicked.

  • Dynamic Control loading at wrong time?

    - by Telos
    This one is a little... odd. Basically I have a form I'm building using ASP.NET Dynamic Data, which is going to utilize several custom field templates. I've just added another field to the FormView, with it's own custom template, and the form is loading that control twice for no apparent reason. Worse yet, the first time it loads the template, the Row is not ready yet and I get the error message: {"Databinding methods such as Eval(), XPath(), and Bind() can only be used in the context of a databound control."} I'm accessing the Row variable in a LinqDataSource OnSelected event in order to get the child object... Now for the wierd part: If I reorder the fields a little, the one causing the problem no longer gets loaded twice. Any thoughts? EDIT: I've noticed that Page_Load gets called on the first load (when Row throws an exception if you try to use it) but does NOT get called the second time around. If that helps any... Right now managing it by just catching and ignoring the exception, but still a little worried that things will break if I don't find the real cause. EDIT 2: I've traced the problem to using FindControl recursively to find other controls on the page. Apparently FindControl can cause the page lifecycle events (at least up to page_load) to fire... and this occurs before that page "should" be loading so it's dynamic data "stuff" isn't ready yet.

  • How to use jQuery to show/hide divs based on radio button selection?

    - by manoj382
    Hello, I have some radio buttons and I'd like to have different hidden divs show up based on which radio button is selected. Here's what the HTML looks like: <form name="form1" id="my_form" method="post" action=""> <div><label><input type="radio" name="group1" value="opt1">opt1</label></div> <div><label><input type="radio" name="group1" value="opt2">opt2</label></div> <div><label><input type="radio" name="group1" value="opt3">opt3</label></div> <input type="submit" value="Submit"> </form> .... <style type="text/css"> .desc { display: none; } </style> .... <div id="opt1" class="desc">lorem ipsum dolor</div> <div id="opt2" class="desc">consectetur adipisicing</div> <div id="opt3" class="desc">sed do eiusmod tempor</div> And here's my jQuery: $(document).ready(function(){ $("input[name$='group2']").click(function() { var test = $(this).val(); $("#"+test).show(); }); }); The reason I'm doing it that way is because my radio buttons and divs are being generated dynamically (the value of the radio button will always have a corresponding div). The code above works partially - the divs will show when the correct button is checked, but I need to add in some code to make the divs hide again once the button is unchecked. Thanks!

  • POST variables to web server?

    - by OverTheRainbow
    Hello I've been trying several things from Google to POST data to a web server, but none of them work: I'm still stuck at how to convert the variables into the request, considering that the second variable is an SQL query so it has spaces. Does someone know the correct way to use a WebClient to POST data? I'd rather use WebClient because it requires less code than HttpWebRequest/HttpWebResponse. Here's what I tried so far: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim wc = New WebClient() 'convert data wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded") Dim postData = String.Format("db={0}&query={1}", _ HttpUtility.UrlEncode("books.sqlite"), _ HttpUtility.UrlEncode("SELECT id,title FROM boooks")) 'Dim bytArguments As Byte() = Encoding.ASCII.GetBytes("db=books.sqlite|query=SELECT * FROM books") 'POST query Dim bytRetData As Byte() = wc.UploadData("http://localhost:9999/get", "POST", postData) RichTextBox1.Text = Encoding.ASCII.GetString(bytRetData) Exit Sub Dim client = New WebClient() Dim nv As New Collection nv.Add("db", "books.sqlite") nv.Add("query", "SELECT id,title FROM books") Dim address As New Uri("http://localhost:9999/get") 'Dim bytRetData As Byte() = client.UploadValues(address, "POST", nv) RichTextBox1.Text = Encoding.ASCII.GetString(bytRetData) Exit Sub 'Dim wc As New WebClient() 'convert data wc.Headers.Add("Content-Type", "application/x-www-form-urlencoded") Dim bytArguments As Byte() = Encoding.ASCII.GetBytes("db=books.sqlite|query=SELECT * FROM books") 'POST query 'Dim bytRetData As Byte() = wc.UploadData("http://localhost:9999/get", "POST", bytArguments) RichTextBox1.Text = Encoding.ASCII.GetString(bytRetData) Exit Sub End Sub Thank you.

    On my form I have a discount field that accepts a dollar amount to be taken off of the total bill (HTML generated in PHP): echo "<input id=\"discount\" class=\"text\" type=\"text\" name=\"discount\" onkeypress=\"return currency(this, event)\" onchange=\"currency_format(this)\" onfocus=\"on_focus(this)\" onblur=\"on_blur(this); calculate_bill()\"/><br/><br/>\n"; The JavaScript function calculate_bill calculates the bill and takes off the discount amount as long as the discount amount is less than the total bill: if(discount != ''){ if(discount - 0.01 > total_bill){ window.alert('Discount Cannot Be Greater Than Total Bill'); document.form.discount.focus(); } else{ total_bill -= discount; } } The problem is that even that when the discount is more than the total bill focus is not being returned to the discount field. I have tried calling the calculate_bill function with onchange but neither IE or Firefox will return focus to the discount field when I do it like that. When I call calculate_bill with onblur it works in IE, but still does not work in Firefox. I have attempted to use a confirmation box instead of an alert box as well, but that didn't work either (plus I don't want two buttons, I only an "OK" button). How can I ensure focus is returned to the discount field after a user has left that field by clicking on another field or tabbing IF the discount amount is larger than the total bill?

  • How do I sanitize a string in PHP that contains "; Echo"? (I have a solid reason)

    - by user337878
    I turned this case into a simple PHP page that submits to itself. My issue is that I am submitting track meet results and one of the girl's names is Echo...a lovely name. The problem text I'm submitting is: Pole vault - Rachel Simons, Tow, 8-6; Echo Wilson, Cit, 8-0; Molly Randall, Tow, 7-0; So you see a semicolon followed by white space followed by Echo... After submitting, it says: POST to /results/test.php not supported The end goal is to save it to a database along with some other info and have a search page to find it and simply print out the full result on the screen. I stripped out all my database stuff to get it down to this one error. I mean, I can intentionally mis-spell her name, but there's gotta be a way around this, right??? Here's the test PHP file. <html> <head> <title>title</title> </head> <body> <?php echo "<h3>Edit meet info below</h3>"; echo "<form action=\"test.php\" method=\"post\" id=\"submitForm\">"; echo "Full Results:<br/><textarea NAME=\"results\" id=\"results\" rows=\"20\" cols=\"80\" MAXLENGTH=\"8191\"></textarea><br/><br/>"; echo "<input type=\"submit\" name=\"submitMeet\" value=\"Submit\">"; echo "</form>"; ?> </body> </html>

  • how to make an import library

    - by user295030
    a requirement was sent to me below: API should be in the form of static library. company xxx will link the library into a third party application to prevent any possible exposure of the code(dll) could they mean an import library? An import library is a library that automates the process of loading and using a dynamic library. On Windows, this is typically done via a small static library (.lib) of the same name as the dynamic library (.dll). The static library is linked into the program at compile time, and then the functionality of the dynamic library can effectively be used as if it were a static library. this might be what they might be eluding to.....I am not sure how to make this in vs2008 . Additional facts: I have a static lib that i use in my current application. Now, I have to convert my app that uses that static lib into an import lib so that they can use a third party prog to access the API's they providede me which in turn will use that static lib i am using. I hope I am clearly explaining this. I am just not sure how to go about it in vs2008. I am looking for specific steps to do this. I already have the coding done. Just need to convert it into the form they are asking and I have to provide the API they want. Other than that then I need to create a test prog which will act as that third party prog so I can make sure my import library works.
