Drupal - Search box not working - custom theme template

- by vr3690

Hello, I am using a customised version of search-theme-from.tpl When I use the search box, I do get transferred to the search page. But the search does not actually take place. The search box on the search results page does work though. This is my search-them-form.tpl.php file (demo : <input type="text" name="search_theme_form_keys" id="edit-search-theme-form-keys" value="Search" title="Enter the terms you wish to search for" class="logininput" height="24px" onblur="restoreSearch(this)" onfocus="clearInput(this)" /> <input type="submit" name="op" id="edit-submit" value="" class="form-submit" style="display: none;" /> <input type="hidden" name="form_token" id="edit-search-theme-form-form-token" value="<?php print drupal_get_token('search_theme_form'); ?>" /> <input type="hidden" name="form_id" id="edit-search-theme-form" value="search_theme_form" /> There is also a javascript file involved. I guess it's use is pretty clear from the code: function trim(str) { return str.replace(/^\s+|\s+$/g, ''); } function clearInput(e) { e.value=""; // clear default text when clicked e.className="longininput_onfocus"; //change class } function restoreSearch(e) { if (trim(e.value) == '') { { e.value="Search"; // reset default text onBlur e.className="logininput"; //reset class } } } What can be the problem and how can I fix it?

Validating Checkbox and Radio Button in C#

- by Solution

Hi, I am using c# for coding! Below is my html for checkbox and radion button <input type="radio" style="float: left;" name="documents" id="Checkbox9" value="yes" runat="server" /> <label style="width: 35px!important;" class="checkbox"> <%=GetResourceString("c_HSGStudent")%> </label> <input type="radio" style="float: left;" name="documents" id="Checkbox10" value="no" runat="server" /> <label style="width: 25px!important;" class="checkbox"> <%=GetResourceString("c_HSGParent")%> </label> <input type="radio" style="float: left;" cheked name="documents" id="Radio1" value="yes" runat="server" /> <label style="width: 35px!important;" class="checkbox"> <%=GetResourceString("c_HSGStudent")%> </label> <input type="radio" style="float: left;" name="documents" id="Radio2" value="no" runat="server" /> <label style="width: 25px!important;" class="checkbox"> <%=GetResourceString("c_HSGParent")%> </label> You can see I have two checkboxes and two radio buttons, My problem is that on my submit button click I want to check whether user have checked at-least one checkbox or radio button.

Adding with PHP to a MySQL database

- by shinjuo

I am pretty new to PHP and I am trying to make an inventory database. I have been trying to make it so that a user can enter a card ID and then amount the want to add to the inventory and have it update the inventory. For example someone could type in test and 2342 and it would update test. Here is what I have been trying with no success: add.html <body> <form action="add.php" method="post"> Card ID: <input type="text" name="CardID" /> Amount to Add: <input type="text" name="Add" /> <input type="submit" /> </form> </body> </html> add.php <?php $link = mysql_connect('tulsadir.ipowermysql.com', 'cbouwkamp', '!starman1'); if (!$link){ die('Could not connect: ' . mysql_error()); } mysql_select_db("tdm_inventory", $link); $add = $_POST[Add] mysql_query("UPDATE cardLists SET AmountLeft = '$add' WHERE cardID = 'Test'"); echo "test successful"; mysql_close($link); ?>

How to manage large amounts of delegates and usercallbacks in C# async http library

- by Tyler

I'm coding a .NET library in C# for communicating with XBMC via its JSON RPC interface using HTTP. I coded and released a preliminary version but everything is done synchronously. I then recoded the library to be asynchronous for my own purposes as I was/am building an XBMC remote for WP7. I now want to release the new async library but want to make sure it's nice and tidy before I do. Due to the async nature a user initiates a request, supplies a callback method that matches my delegate and then handles the response once it's been received. The problem I have is that within the library I track a RequestState object for the lifetime of the request, it contains the http request/response as well as the user callback etc. as member variables, this would be fine if only one type of object was coming back but depending on what the user calls they may be returned a list of songs or a list of movies etc. My implementation at the moment uses a single delegate ResponseDataRecieved which has a single parameter which is a simple Object - As this has only be used by me I know which methods return what and when I handle the response I cast said object to the type I know it really is - List, List etc. A third party shouldn't have to do this though - The delegate signature should contain the correct type of object. So then I need a delegate for every type of response data that can be returned to the third party - The specific problem is, how do I handle this gracefully internally - Do I have a bunch of different RequestState objects that each have a different member variable for the different delegates? That doesn't "feel" right. I just don't know how to do this gracefully and cleanly.

Issue selenium code maintenance

- by Rajasankar

I want to group the common methods in one file and use it. For example, login to a page using selenium may be used in multiple times. Define that in class A and call it in class B. However, it throws null pointer exception. class A has public void test_Login() throws Exception { try{ selenium.setTimeout("60000"); selenium.open("http://localhost"); selenium.windowFocus(); selenium.windowMaximize(); selenium.windowFocus(); selenium.type("userName", "admin"); selenium.type("password", "admin"); Result=selenium.isElementPresent("//input[@type='image']"); selenium.click("//input[@type='image']"); selenium.waitForPageToLoad(Timeout); } catch(Exception ex) { System.out.println(ex); ex.printStackTrace(); } } with all other java syntax in class B public void test_kk() throws Exception { try { a.test_Login(); } catch(Exception ex) { System.out.println(ex); ex.printStackTrace(); } } with all syntax.

jQuery validate plugin radio with optional text

- by timborden

I'm trying to figure out how to validate a form element with a mix of radio inputs and a text input: <label>Question?</label> <input type="radio" class="mandatory" name="questions[1][]" value="1" />answer 1<br/> <input type="radio" class="mandatory" name="questions[1][]" value="2" />answer 2<br/> <input class="ignore" type="radio" id="questions[1][]" />Other (please specify)<br/> <input class="optional mandatory" type="text" name="questions[1][]" value="" /> I've figured out how to get the form to behave as expected (select and unselect) with the following code: $("input.optional").focus(function () { var this_name = $(this).attr("name"); $("input:radio").filter(function() {return $(this).attr('name') == this_name; }).attr('checked', false); $("input").filter(function() {return $(this).attr('id') == this_name; }).attr('checked', true); }); $(':radio').click(function () { var this_name = $(this).attr("name"); $("input").filter(function() {return $(this).attr('id') == this_name; }).attr('checked', false); $("input.optional").filter(function() {return $(this).attr('name') == this_name; }).val(''); }); I was hoping I could use the class "mandatory" to validate the mix of radio and text inputs: $("form .manditory").each(function () { $(this).rules("add", {required: true}); }); But it's not working as expected. With the radio (id="questions[1][]") selected, and the text input containing content, the form element is still flagged as invalid. Suggestions...maybe a better approach? Thanks in advance. UPDATE Sorry, I should have clarified that I'm using the validate plugin: $("form").validate({ ... });

Radio buttons change variable in JavaScript

- by dmanexe

I have two fields which calculate a total, but I have a radio button pair that determines a variable within the equation. Here's the radio button code: <input type="radio" name="estimate_pool_shape" value="1" /> Angle <input type="radio" name="estimate_pool_shape" value=".86392" /> Freeform Immediately after that, this JavaScript is then calculating the surface area of the pool based of these fields and script: (Length <input type="text" size="5" name="estimate_pool_length" onBlur="conv2inches(document.forms.mainform);" />) x (Width <input type="text" name="estimate_pool_width" size="5" onBlur="conv2inches(document.forms.mainform);" />) The following JavaScript already works to update the fields, I just need the variable it uses to set the field values to change based on the radio buttons. function conv2inches(mainform) { var oin; var oinches; if(isNaN(mainform.estimate_pool_width.value)||isNaN(mainform.estimate_pool_length.value)){ alert("Please enter numbers only"); return false; } oin = ((mainform.estimate_pool_width.value) + (mainform.estimate_pool_length.value) * %%%RADIO BUTTON VARIABLE HERE%%%); oinches = (oin); if(oinches==0){ alert("Please enter valid values into the boxes"); } mainform.estimate_pool_sqft.value = oinches; return false; }

Select multi-select form from array

- by Budove

Here's the issue. I have a database column called pymnt_meth_pref, which contains a comma separated string of payment methods chosen from a multiselect form. <td>Payment Methods Used:<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Cash">I can pay with cash.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Check">I can pay by check.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Credit Card">I can pay by credit card.<br /> <input type="checkbox" name="pyment_meth_pref[]" value="Paypal">I can pay with Paypal.<br /> </td> This array is posted to a variable and turned into a comma separated string if (isset($_POST['pyment_meth_pref'])) $pymntmethpref = implode(", ", $_POST['pyment_meth_pref']); if (isset($_POST['pyment_meth_acc'])) $pymntmethacc = implode(", ", $_POST['pyment_meth_acc']); This is then inserted into the database as a comma separated string. What I would like to do, is take this string and apply the values to the original form when the user goes back to the form as 'pre-selected' checkboxes, indicated that the user has already selected those values previously, and keeping those values in the database if they choose to edit any other information in the form. I'm assuming this would need to be done with javascript but if there is a way to do it with PHP I'd rather do it that way.

EventAggregator, is it thread-safe?

- by pfaz

Is this thread-safe? The EventAggregator in Prism is a very simple class with only one method. I was surprised when I noticed that there was no lock around the null check and creation of a new type to add to the private _events collection. If two threads called GetEvent simultaneously for the same type (before it exists in _events) it looks like this would result in two entries in the collection. /// <summary> /// Gets the single instance of the event managed by this EventAggregator. Multiple calls to this method with the same <typeparamref name="TEventType"/> returns the same event instance. /// </summary> /// <typeparam name="TEventType">The type of event to get. This must inherit from <see cref="EventBase"/>.</typeparam> /// <returns>A singleton instance of an event object of type <typeparamref name="TEventType"/>.</returns> public TEventType GetEvent<TEventType>() where TEventType : EventBase { TEventType eventInstance = _events.FirstOrDefault(evt => evt.GetType() == typeof(TEventType)) as TEventType; if (eventInstance == null) { eventInstance = Activator.CreateInstance<TEventType>(); _events.Add(eventInstance); } return eventInstance; }

How to store and locate multiple interface types within a Delphi TInterfaceList

- by Brian Frost

Hi, I'm storing small interfaces from a range of objects into a single TInterfaceList 'store' with the intention of offering list of specific interface types to the end user, so each interface will expose a 'GetName' function but all other methods are unique to that interface type. For example here are two interfaces: IBase = interface //---------------------------------------- function GetName : string; //---------------------------------------- end; IMeasureTemperature = interface(IBase) //------------------------------------ function MeasureTemperature : double; //---------------------------------------- end; IMeasureHumidity = interface(IBase) //---------------------------------------- function MeasureHumidity: double; //---------------------------------------- end; I put several of these interfaces into a single TInterfaceList and then I'd like to scan the list for a specific interface type (e.g. 'IMeasureTemperature') building another list of pointers to the objects exporting those interfaces. I wish to make no assumptions about the locations of those objects, some may export more than one type of interface. I know I could do this with a class hierarchy using something like: If FList[I] is TMeasureTemperature then .. but I'd like to do something simliar with an interface type, Is this possible?

multiple form submission with one submit

- by skylab

I've been trying to think this through and figure out if it is possible or not. I'm using zen-cart as shopping cart software, but what I'd like to do, is hard code a page that is basically a list of 7-9 products, next to each product is a checkbox, so I'd like to figure out a way, via html,javascript or jquery to submit whichever forms(products) are checked to the cart. The typical form submission for a product looks something like this(sometimes there may be one or two additional hidden fields): <form name="cart_quantity" action="index.php?action=add_product" method="post" enctype="multipart/form-data"> <input type="hidden" name="cart_quantity" value="1"> <input type="hidden" name="products_id" value="7"> <input type="hidden" name="id[6]" value="9" id="attrib-6-9"> <input type="image" src="buy_button.png" alt="Add to Cart" title="Instructional Video Part 1: Add to Cart"> </form> There would be 7-9 of these on the page, each with a checkbox, so I'm assuming a script would need to figure out which ones where checked and submit them via the form action? Maybe there is a better way of going about this that I'm not thinking of because a)it's over my head or b)just haven't figured it out yet. Anyway is something like this possible?

GADTs and Scrap your Boilerplate

- by finnsson

I'm writing a XML (de)serializer using Text.XML.Light and Scrap your Boilerplate (at http://github.com/finnsson/Text.XML.Generic) and so far I got working code for "normal" ADTs but I'm stuck at deserializing GADTs. I got the GADT data DataBox where DataBox :: (Show d, Eq d, Data d) => d -> DataBox and I'm trying to get this to compile instance Data DataBox where gfoldl k z (DataBox d) = z DataBox `k` d gunfold k z c = k (z DataBox) -- not OK toConstr (DataBox d) = toConstr d dataTypeOf (DataBox d) = dataTypeOf d but I can't figure out how to implement gunfold for DataBox. The error message is Text/XML/Generic.hs:274:23: Ambiguous type variable `b' in the constraints: `Eq b' arising from a use of `DataBox' at Text/XML/Generic.hs:274:23-29 `Show b' arising from a use of `DataBox' at Text/XML/Generic.hs:274:23-29 `Data b' arising from a use of `k' at Text/XML/Generic.hs:274:18-30 Probable fix: add a type signature that fixes these type variable(s) It's complaining about not being able to figure out the data type of b. I'm also trying to implement dataCast1 and dataCast2 but I think I can live without them (i.e. an incorrect implementation). I guess my questions are: Is it possible to combine GADTs with Scrap your Boilerplate? If so: how do you implement gunfold for a GADT?

Namespace scoped aliases for generic types in C#

- by TN

Let's have a following example: public class X { } public class Y { } public class Z { } public delegate IDictionary<Y, IList<Z>> Bar(IList<X> x, int i); public interface IFoo { // ... Bar Bar { get; } } public class Foo : IFoo { // ... public Bar Bar { get { return null; //... } } } void Main() { IFoo foo; //= ... IEnumerable<IList<X>> source; //= ... var results = source.Select(foo.Bar); } The compiler says: The type arguments for method 'System.Linq.Enumerable.Select(System.Collections.Generic.IEnumerable, System.Func)' cannot be inferred from the usage. Try specifying the type arguments explicitly. It's because, it cannot convert Bar to Func<IList<X>, int, IDictionary<Y, IList<Z>>>. It would be great if I could create type namespace scoped type aliases for generic types in C#. Then I would define Bar not as a delegate, but rather I would define it as an namespace scoped alias for Func<IList<X>, int, IDictionary<Y, IList<Z>>>. public alias Bar = Func<IList<X>, int, IDictionary<Y, IList<Z>>>; I could then also define namespace scoped alias for e.g. IDictionary<Y, IList<Z>>. And if used appropriately:), it will make the code more readable. Now I have inline the generic types and the real code is not well readable:( Have you find the same trouble:)? Is there any good reason why it is not in C# 3.0? Or there is no good reason, it's just matter of money and/or time? EDIT: I know that I can use using, but it is not namespace based - not so convenient for my case.

Inheritance of TCollectionItem

- by JamesB

I'm planning to have collection of items stored in a TCollection. Each item will derive from TBaseItem which in turn derives from TCollectionItem, With this in mind the Collection will return TBaseItem when an item is requested. Now each TBaseItem will have a Calculate function, in the the TBaseItem this will just return an internal variable, but in each of the derivations of TBaseItem the Calculate function requires a different set of parameters. The Collection will have a Calculate All function which iterates through the collection items and calls each Calculate function, obviously it would need to pass the correct parameters to each function I can think of three ways of doing this: Create a virtual/abstract method for each calculate function in the base class and override it in the derrived class, This would mean no type casting was required when using the object but it would also mean I have to create lots of virtual methods and have a large if...else statement detecting the type and calling the correct "calculate" method, it also means that calling the calculate method is prone to error as you would have to know when writing the code which one to call for which type with the correct parameters to avoid an Error/EAbstractError. Create a record structure with all the possible parameters in and use this as the parameter for the "calculate" function. This has the added benefit of passing this to the "calculate all" function as it can contain all the parameters required and avoid a potentially very long parameter list. Just type casting the TBaseItem to access the correct calculate method. This would tidy up the TBaseItem quite alot compared to the first method. What would be the best way to handle this collection?

Inline form fields with labels placed on top

I can't believe I'm having to ask this, but I'm at my wit's end. I'm trying to display 2 form fields inline, but with the label for each field on the top. In ascii art: Label 1 Label 2 --------- --------- | | | | --------- --------- Should be pretty simple. <label for=foo>Label 1</label> <input type=text name=foo id=foo /> <label for=bar>Label 2</label> <input type=text name=bar id=bar /> This will get me: --------- --------- Label 1 | | Label 2 | | --------- --------- To get the labels on top of the boxes, I add display=block: <label for=foo style="display:block">Label 1</label> <input type=text name=foo id=foo /> <label for=bar style="display:block">Label 2</label> <input type=text name=bar id=bar /> After I do this, the labels are where I want them, but the form fields are no longer inline: Label 1 --------- | | --------- Label 2 --------- | | --------- I've been unable to find a way to wrap my html so the fields display inline. Can anyone help?

On checkbox checked show radio button

- by aDameToKillFor

Hello, I would like to ask for a little help here, since I haven't got any big knowledge in Javascript, nor in jQuery. I need to show 5 radio buttons when a checkbox is checked, the checkboxes represent languages that the user speaks, so for each of the selected, there should appear 5 separate radio buttons for how good they speak it(1 to 5). I tried to do it with jQuery, but I did not manage to get very far away... This is where my checkboxes are created(dynamically): <% for(int i = 0; i < Model.Languages.Count; i++) { %> <input id="applang" name="applang" type="checkbox" value="<%: Model.Languages[i].languageID%>" /> <%: Model.Languages[i].name.ToString() %><br /> <%} %> So, I tried to add this script, but it's not working: <script type="text/javascript"> $("input[@name='applang']").click(function () { $("input[type='radio']").show(); }); I also tried this way - to use this javascript: <script type="text/javascript"> function toggle_visibility(id) { var e = document.getElementById(id); if (e.style.display == 'block') e.style.display = 'none'; else e.style.display = 'block'; } And it works, but it works on already present controls, and I guess I need to create mine dynamically, or maybe not? And I tried to hide a present control with CSS, but then when the script shows it, it is there, only invisible :) Also, I would want to get the name and value of the radio buttons from my database, i.e. Model(this is ASP.NET MVC).. Can someone help me a little bit, please?

This is the code i'm currently using: (note - %s is replaced on the server side)  <object type="application/x-java-applet" width="300" height="300" >   <param name="codebase" value="/media/vnc/" > <param name="archive" value="TightVncViewer.jar" /> <param name="code" value="com.tightvnc.vncviewer.VncViewer" /> <param name="port" value="%s" /> <param name="Open New Window" value="yes" /> </object> When Java is installed, this works perfectly in both IE and Firefox. When Java is not installed, IE and Firefox both correctly prompt for an autodownload of Java 1.6 from the codebase line. (IE via the activex url given firefox via the Plugin Finder Service) Now, suppose I want fallback content to be shown if the plugin isn't installed, say a simple message like "Get Java". From reading the specs, i'd assume this should not change the plugin finding prompt - that is, rendering the fallback should be seen as a failure to render the object tag. Thus, I should still get the plugin finder service prompting me to install Java. Instead, simply adding a single character to the innerHTML of the object element causes Firefox to no longer prompt. Test this by visiting data:text/html,<object type='application/x-java-applet'>Java failed to load</object>. How can I keep firefox prompting to install Java while providing fallback content? URL to test Firefox's Java Plugin Finder Service: data:text/html,<object type='application/x-java-applet'/>

HTML/CSS: Keep the same height between the backgrounds of a term-description pair in a table-like de

- by peroyomas

I want to format a definition list in HTML as if it were a table with th in a column and td in another, with a background that alternates per row (although a background for the dt and another for the dd also fits for the problem), so I have this CSS: dl { font-family: Verdana, Geneva, sans-serif; font-size: 0.6em; overflow: hidden; width: 200px;; } dl dt { font-weight: bold; float: left; clear: left; padding-right: 1%; width: 48%; } dl dt:nth-of-type(odd), dl dd:nth-of-type(odd) { background-color: #EEE; } dl dt:nth-of-type(even), dl dd:nth-of-type(even) { background-color: #DDD; } dl dd { float: left; width: 50%; padding-left: 1%; margin-left: 0; } Example HTML: <dl> <dt>Key 1</dt> <dd>Value 1</dd> <dt>Very very very long key 2 </dt> <dd>Value 2</dd> <dt>Key 3</dt> <dd>Value 3 with<br /> line breaks</dd> <dt>Key 4</dt> <dd>Value 4</dd> </dl> The problem is that, due to the eventual height dissimilarity, "holes" with no background appears in the list: Is there a way to fix that?

Handling Denormalized Schema with Eclipselink

- by iamrohitbanga

Hello All I have a denormalized table containing employee information. The fields are employee id, name and department name. The primary key is a composite one consisting of all three fields. An employee can belong to multiple departments. I want to read/write the objects in the table using the Eclipselink Dynamic Persistence API (which is infact a wrapper on top of JPA descriptors etc.). Example Data: 1 e1 dep1 2 e1 dep2 3 e2 dep1 4 e2 dep3 5 e3 dep1 5 e3 dep2 5 e3 dep3 A normal ReadAllQuery (select query) on the table returns a DynamicEntity corresponding to each row in the table. However I want to club all entities based on the emp id and return all the departments he belongs to as a list. I can merge the entities after retrieving them but if I can use some Eclipselink feature out of the box then it would be better. One way to do the read is the following: I create two dynamic types corresponding to employee: Having id,name as the primary key Having id, department as the primary key, I create a OneToManyMapping from the first type to the second one. Then when I query the first type it does return the departments to which employee belongs as a list of DynamicEntity of the second type. This satisfies the read scenario. Is there a better way of doing this? Is this inherently supported by Eclipselink or JPA? I cannot get the same dynamic type configuration working for the write scenario. This is because when I write the changes using the writeObject method of UnitOfWork, it generates insert queries which enter the following entries in the table id name department 102 emp_102 102 st 102 dep_102 102 dep_102 102 dep_102 instead of: id name department 102 emp_102 st 102 emp_102 dep_102 102 emp_102 dep_102 102 emp_102 dep_102 Is there any way I can get write to work with this schema using eclipselink? I want to avoid doing the heavy lifting of merging the rows for such a denormalized schema or generating each row before doing a write. Is there no clean way of doing this using Eclipselink or JPA? Thanks in Advance.
