  • I want to add and remove items from a menu with PHP.

    - by CDeanMartin
    This menu will need to be updated daily. <html><head></head><body> <h1> Welcome to Burgerama </h1> <?php include("menuBuilder.php"); showBurgerMenu(); ?> </body></html> Menu items are stored in the database. Items have a display field; if it is on, the item should be displayed on the menu. The menu only displays 4 or 5 "specials" at a time, and the manager needs to change menu items easily. I want to make a menu editing page like this: <?php include("burger_queries.php"); dbconnect("burger_database"); foreach($menuItem in burger_database) { echo createToggleButton($menuItem); } ?> .. with a toggle button for each menu item. Ideally the button will be labeled with the menu item, in blue if the item is "on", and red if the item is "off." Clicking the button switches between "on" and "off" I am stuck trying to a get a button to execute an UPDATE query on its corresponding menu item.

  • Deleting list items via ProcessBatchData()

    - by q-tuyen
    You can build a batch string to delete all of the items from a SharePoint list like this: 1: //create new StringBuilder 2: StringBuilder batchString= new StringBuilder(); 3: 4: //add the main text to the stringbuilder 5: batchString.Append(""); 6: 7: //add each item to the batch string and give it a command Delete 8: foreach (SPListItem item in itemCollection) 9: { 10: //create a new method section 11: batchString.Append(""); 12: //insert the listid to know where to delete from 13: batchString.Append("" + Convert.ToString(item.ParentList.ID) + ""); 14: //the item to delete 15: batchString.Append("" + Convert.ToString(item.ID) + ""); 16: //set the action you would like to preform 17: batchString.Append("Delete"); 18: //close the method section 19: batchString.Append(""); 20: } 21: 22: //close the batch section 23: batchString.Append(""); 24: 25: //preform the batch 26: SPContext.Current.Web.ProcessBatchData(batchString.ToString()); The only disadvantage that I can think of right know is that all the items you delete will be put in the recycle bin. How can I prevent that? I also found the solution like below: // web is a the SPWeb object your lists belong to // Before starting your deletion web.Site.WebApplication.RecycleBinEnabled = false; // When your are finished re-enable it web.Site.WebApplication.RecycleBinEnabled = true; Ref [Here](http://www.entwicklungsgedanken.de/2008/04/02/how-to-speed-up-the-deletion-of-large-amounts-of-list-items-within-sharepoint/) But the disadvantage of that solution is that only future deletion will not be sent to the Recycle Bins but it will delete all existing items as well which user do not want. Any idea to prevent not to delete existing items? Many thanks in advance, TQT

  • Two references to the same domain/entity model

    - by Sbossb
    Problem I want to save the attributes of a model that have changed when a user edits them. Here's what I want to do ... Retrieve edited view model Get domain model and map back updated value Call the update method on repository Get the "old" domain model and compare values of the fields Store the changed values (in JSON) into a table However I am having trouble with step number 4. It seems that the Entity Framework doesn't want to hit the database again to get the model with the old values. It just returns the same entity I have. Attempted Solutions I have tried using the Find() and the SingleOrDefault() methods, but they just return the model I currently have. Example Code private string ArchiveChanges(T updatedEntity) { //Here is the problem! //oldEntity is the same as updatedEntity T oldEntity = DbSet.SingleOrDefault(x => x.ID == updatedEntity.ID); Dictionary<string, object> changed = new Dictionary<string, object>(); foreach (var propertyInfo in typeof(T).GetProperties()) { var property = typeof(T).GetProperty(propertyInfo.Name); //Get the old value and the new value from the models var newValue = property.GetValue(updatedEntity, null); var oldValue = property.GetValue(oldEntity, null); //Check to see if the values are equal if (!object.Equals(newValue, oldValue)) { //Values have changed ... log it changed.Add(propertyInfo.Name, newValue); } } var ser = new System.Web.Script.Serialization.JavaScriptSerializer(); return ser.Serialize(changed); } public override void Update(T entityToUpdate) { //Do something with this string json = ArchiveChanges(entityToUpdate); entityToUpdate.AuditInfo.Updated = DateTime.Now; entityToUpdate.AuditInfo.UpdatedBy = Thread.CurrentPrincipal.Identity.Name; base.Update(entityToUpdate); }

  • Eval string for wordpress "in_category" workaround outside the loop

    - by fimbim
    In Wordpress you can´t use "in_category" outside the loop, so I created a function that gives me all the categories my article is in and create a "is_category" if statement out of it. I put my function in my "functions.php": function inCatAlt($catID){ $allCats = get_categories('child_of='.$catID); $childCats = 'is_category('.$catID.') '; foreach($allCats as $childCat){ $childCats.= 'or is_category('.$childCat->cat_ID.') '; }; $allchildCats = trim(trim($childCats, 'or ')); return $allchildCats; } and call this in my sidebar, single and so on: echo inCatAlt(13); which gives me this as a string back: "is_category(13) or is_category(16) or is_category(15)" This is exactly what I needed, but now I want to evaluate the string to use it in a if function like this: if(eval(inCatAlt(13))){ do something } But it doesn´t work. Do I evaluate it wrong or what is the problem? If I copy paste the output into the if function it works fine… Thanks in advanced guys. Is my first time asking something here. I´m curious :)

  • Kohana 3, problem with m2m data adding

    - by Marek
    Hello I posted this on official forum but with no result. I am getting :Undefined index: enrollment error when trying to save data. My pivot model: class Model_Enrollment extends ORM { protected $_belongs_to = array('page' => array(), 'menugroup' => array()); } Model_Page protected $_has_many = array('templates' => array(), 'menugroups' => array('through' => 'enrollment')); Model_Menugroup protected $_has_many = array('menuitems' => array(), 'pages' => array('through' => 'enrollment')); //Overriden save() method in Model_Menugroup: public function save() { if (empty($this->created)) { $this->created = time(); } parent::save(); $this->reload(); if (! $this->is_global) { if (! empty($this->groupOwnerPagesId) { $page = ORM::factory('page'); foreach($this->groupOwnerPagesId as $id) { $this->add('enrollment', $page->find($id)); } } } } I did: I corrected table names in pivot model by changing them to singular I even now using the same name for pivot table / model = enrollment. The same as in tutorial. Just in case So the pivot table has name 'enrollment' and has 2 columns: page_id , menugroup_id I tried to add pk in pivot table, but it changed nothing I tried to add/remove db relation between pages/menugroups and pivot table (InnoDB) but with no luck I tried save all data in controller, but with the same bad result:( I am still getting the same error: Undefined index: enrollment in ORM line: $columns = array($this-_has_many[$alias]['foreign_key'], $this-_has_many[$alias]['far_key']); Could somebody tell me, what can be else wrong? I have no other ideas:( Kind regards

  • Query Parameter Value Is Null When Enum Item 0 is Cast to Int32

    - by Timothy
    When I use the first item in a zero-based Enum cast to Int32 as a query parameter, the parameter value is null. I've worked around it by simply setting the first item to a value of 1, but I was wondering though what's really going on here? This one has me scratching my head. Why does the parameter regarded the value as null, instead of 0? Enum LogEventType : int { SignIn, SignInFailure, SignOut, ... } private static DataTable QueryEventLogSession(DateTime start, DateTime stop) { DataTable entries = new DataTable(); using (FbConnection conn = new FbConnection(DSN)) { using (FbDataAdapter adapter = new FbDataAdapter( "SELECT event_type, event_timestamp, event_details FROM event_log " + "WHERE event_timestamp BETWEEN @start AND @stop " + "AND event_type IN (@signIn, @signInFailure, @signOut) " + "ORDER BY event_timestamp ASC", conn)) { adapter.SelectCommand.Parameters.AddRange(new Object[] { new FbParameter("@start", start), new FbParameter("@stop", stop), new FbParameter("@signIn", (Int32)LogEventType.SignIn), new FbParameter("@signInFailure", (Int32)LogEventType.SignInFailure), new FbParameter("@signOut", (Int32)LogEventType.SignOut)}); Trace.WriteLine(adapter.SelectCommand.CommandText); foreach (FbParameter p in adapter.SelectCommand.Parameters) { Trace.WriteLine(p.Value.ToString()); } adapter.Fill(entries); } } return entries; }

  • Determine if a directory is empty, delete it if it is and delete that directroy name from a separate list. C-shell

    - by Kg123
    I have a directory named STA. Within that directory are about 600 other directories that have the format hh:mm:ss (for example 00:01:34). Within each of these sub-directories should be three files. I also have a file, 'waveformlist', (contained within STA) which is a list of all of these sub-directories i.e.: 00:01:34 00:02:35 etc. A lot of the sub-directories do not contain these three files and are instead empty. I want to run a C-shell script to go through every sub directory and check if it is empty. If it is empty I want to delete that sub directory from the main directory STA, and also remove that sub-directory name from the list 'waveformlist'. Below is my script so far. It does not recognize when the sub-directory is empty or not and does not like the rm $dir line. Also, I do not know how to go and remove the sub-directory name from 'waveformlist'. #!/bin/csh echo "Enter name of station folder to apply filter to as 'STA' e.g. APZ:" set ans = $< cd $ans set c=0 foreach dir (*:*) if ("${c}" == 0) then echo "Empty directory:" $dir rm $dir else echo ${dir} "has files" endif end I hope I have been clear enough. Thank you.

  • Merging multiple docx files to one

    - by coding
    I am developing a desktop application in C#. I have coded a function to merge multiple docx files but it does not work as expected. I don't get the content exactly as how it was in the source files. A few blank lines are added in between. The content extends to the next pages, header and footer information is lost, page margins gets changed, etc.. How can I concatenate docs as it is without and change in it.Any suggestions will be helpful. This is my code. public bool CombineDocx(string[] filesToMerge, string destFilepath) { Application wordApp = null; Document wordDoc = null; object outputFile = destFilepath; object missing = Type.Missing; object pageBreak = WdBreakType.wdPageBreak; try { wordApp = new Application { DisplayAlerts = WdAlertLevel.wdAlertsNone, Visible = false }; wordDoc = wordApp.Documents.Add(ref missing, ref missing, ref missing, ref missing); Selection selection = wordApp.Selection; foreach (string file in filesToMerge) { selection.InsertFile(file, ref missing, ref missing, ref missing, ref missing); selection.InsertBreak(ref pageBreak); } wordDoc.SaveAs( ref outputFile, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing); return true; } catch (Exception ex) { Msg.Log(ex); return false; } finally { if (wordDoc != null) { wordDoc.Close(); } if (wordApp != null) { wordApp.DisplayAlerts = WdAlertLevel.wdAlertsAll; wordApp.Quit(); Marshal.FinalReleaseComObject(wordApp); } } }

  • What is wrong with this php loop?

    I made a loop but it doesn't work. here's what I did: <?php if(is_tree('4')) { ?> <?php $show_after_p = 2; $content = apply_filters('the_content', $post->post_content); if(substr_count($content, '<p>') > $show_after_p) { $contents = explode("</p>", $content); $p_count = 1; foreach($contents as $content) { echo $content; if($p_count == $show_after_p) { ?> YOUR AD CODE GOES HERE < ? } echo "</p>"; $p_count++; } } ?> <?php else : ?> <?php the_content('<p class="serif">Read the rest of this page &raquo;</p>'); ?> <?php endif; } ?> I need to make it work but don't know how.

  • Is there a faster way to access a property member of a class using reflection?

    - by Ross Goddard
    I am currently using the following code to access the property of an object using reflection: Dim propInfo As Reflection.PropertyInfo = myType.GetProperty(propName) Dim objValue As Object = propInfo.GetValue(myObject, Nothing) I am having some issues with the speed since this type of code is being called many times and is causing some slowdown. I have been looking into using Refelction.Emit or dynamic methods, but I am not sure exactly how to make use of them. Background Information: I am creating a list of a subset of the properties of the object, associating then with some meta information (such as if they can be loaded from the database or xml, if they are editable, can the user see them). This is for later consumption so we can write code such as : foreach prop as BaseWrapper in graphNode.NodeProperties prop.LoadFromDataRow(dr) next The application makes heavy use of having access to this list. The problem is that on the initial load of a project, a larger number of objects are being created that make use of this, so for each object created it is looping through this code a number of times. I initially tried adding each property to the list manually, but this ran into problems with not everything being initialized at the correct time and some other issues. If there is no other good way, then I may have to rethink some of the design and see what else can be done to improve the performance.

  • How to check the correct radio button.

    - by MrW
    I have a Table containing some information that I need. All these rows also contains a column with a radio button in it so that the user is suppose to be able to check one of the rows as default. When I'm bringing the data back from the DB and want to select the one that's currentlly the default one. <% foreach (var item in (IEnumerable<Locale>) ViewData["Locales"]) { %> <tr> <td> <%= Html.Encode(item.Language.Name) %> </td> <td> <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%= item.Default == false ? "false" : "true" %>" /> </td> I've also tried to do this: <input type="radio" id="defaultLocale" name="defaultLocele" value="on" checked="<%=item.Default == false ? "" : "checked" %>" /> but nothing seems to do the right thing. I always end up with having the last row in checked, which it isn't for sure.

  • Merging two arrays in PHP

    - by Industrial
    Hi everyone, I am trying to create a new array from two current arrays. Tried array_merge, but it will not give me what I want. $array1 is a list of keys that I pass to a function. $array2 holds the results from that function, but doesn't contain any non-available resuls for keys. So, I want to make sure that all requested keys comes out with 'null':ed values, as according to the shown $result array. It goes a little something like this: $array1 = array('item1', 'item2', 'item3', 'item4'); $array2 = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3' ); Here's the result I want: $result = array( 'item1' => 'value1', 'item2' => 'value2', 'item3' => 'value3', 'item4' => '' ); It can be done this way, but I don't think that it's a good solution - I really don't like to take the easy way out and suppress PHP errors by adding @:s in the code. This sample would obviously throw errors since 'item4' is not in $array2, based on the example. foreach ($keys as $k => $v){ @$array[$v] = $items[$v]; } So, what's the fastest (performance-wise) way to accomplish the same result?

  • Strange behaviour when collapsing lines in XML bound WPF Datagrid

    - by Flossn
    i am using a wpf datagrid with a xml file as DataContext. All working good except for iterating thorough the table and collapsing individual rows. There are several checkboxes where the user can decide which kinds of rows he wants to see, dependent on their error level string. If a checkbox is checked, some of the rows are collapsed, others not. You need to uncheck the checkbox and check it again to collapse the ones of the first try and some of the others. If you recheck it again more rows are collapsed every time. I guess it has something to do with how much of the list is actually visible and how much not because of the window size. Thanks in advance. foreach (DataGridRow r in rows) { bool showRow = true; var tb = Datagrid.GetCell(dataGridEvents, r, 2).Content; string level = ((TextBlock)tb).Text; switch (level) { case "Warning": showRow = checkBoxWarnings.IsChecked.HasValue ? checkBoxWarnings.IsChecked.Value : false; break; case "Critical": showRow = checkBoxCritical.IsChecked.HasValue ? checkBoxCritical.IsChecked.Value : false; break; case "OK": showRow = checkBoxOK.IsChecked.HasValue ? checkBoxOK.IsChecked.Value : false; break; case "Unknown": showRow = checkBoxUnknown.IsChecked.HasValue ? checkBoxUnknown.IsChecked.Value : false; break; } r.Visibility = showRow ? Visibility.Visible : Visibility.Collapsed; }

  • Enabling all buttons in a repeater except for the clicked one

    - by NewAmbition
    I have a Repeater Control with various buttons in it. When the button gets clicked, it needs to disable itself so it cant be clicked again. Working. However, when I click that button, it needs to enable any other button but it. So, When I click on it, it needs to disable. When I click on another one, the previous button must enable, and that one must disable. So for I've tried: Button btnLoad = (Button)e.Item.FindControl("btnLoad"); foreach (Button b in e.Item.Controls.OfType<Button>().Select(c => c).Where(b => b != btnLoad)) { b.Enabled = true; } btnLoad.Text = "Currently Viewing"; btnLoad.Enabled = false; But it isnt working. Depending on where I put it, its either leaving all the buttons enabled (But still changing its text), or not doing anything at all. What do I need to do to make this work?

  • Can I control object creation using MEF?

    - by Akash
    I need to add some extension points to our existing code, and I've been looking at MEF as a possible solution. We have an IRandomNumberGenerator interface, with a default implementation (ConcreteRNG) that we would like to be swappable. This sounds like an ideal scenario for MEF, but I've been having problems with the way we instantiate the random number generators. Our current code looks like: public class Consumer { private List<IRandomNumberGenerator> generators; private List<double> seeds; public Consumer() { generators = new List<IRandomNumberGenerator>(); seeds = new List<double>(new[] {1.0, 2.0, 3.0}); foreach(var seed in seeds) { generators.Add(new ConcreteRNG(seed); } } } In other words, the consumer is responsible for instantiating the RNGs it needs, including providing the seed that each instance requires. What I'd like to do is to have the concrete RNG implementation discovered and instantiated by MEF (using the DirectoryCatalog). I'm not sure how to achieve this. I could expose a Generators property and mark it as an [Import], but how do I provide the required seeds? Is there some other approach I am missing?

  • What would be the best approach to finding a date in a freeform text?

    - by Matthew DeVos
    What would be the best approach to finding a date in a freeform text? A post where a user may place a date in it in several different ways such as: July 14th & 15th 7/14 & 7/15 7-14 & 7-15 Saturday 14th and Sunday 15th Saturday July 14th and 15th and so on. Is regex my best choice for this type of thing with preg_match? I would also like to search if there are two dates, one for a start date and a second for an end date, but in the text I'm searching there may be one date or two. This is my PHP code so far: $dates1 = '01-01'; $dates2 = 'July 14th & 15th'; $dates3 = '7/14 & 7/15'; $dates4 = '7-14 & 7-15'; $dates5 = 'Saturday 14th and Sunday 15th'; $dates6 = 'Saturday July 14th and 15th'; $regexes = array( '/\s(1|2|3|4|5|6|7|8|9|10|11|12)\/\d{1,2}/', //finds a date '/\s(1|2|3|4|5|6|7|8|9|10|11|12)-\d{1,2}/', //finds another date '%\b(0?[1-9]|[12][0-9]|3[01])[- /.](0?[1-9]|1[012])\b%', //finds date format dd-mm or dd.mm ); foreach($regexes as $regex){ preg_match($regex,$dates,$matches); } var_dump($matches);

  • C# XMLWriter + prevent "/" "<" "<" chars

Is there a way to fix this problem?

I need show content in ThickBox all the time, even after the file upload.

  • How to defer execution of an Event on each item in a collection until iteration of collection is com

    - by Metro Smurf
    Of Note: This is more of a curiosity question than anything else. Given a List<Window> where each window has an event attached to the Close Event which removes the window from the collection, how could you use delegates / events to defer the execution of the Close Event until the collection has been iterated? For example: public class Foo { private List<Window> OpenedWindows { get; set; } public Foo() { OpenedWindows = new List<Window>(); } public void AddWindow( Window win ) { win.Closed += OnWindowClosed; OpenedWindows.Add( win ); } void OnWindowClosed( object sender, EventArgs e ) { var win = sender as Window; if( win != null ) { OpenedWindows.Remove( win ); } } void CloseAllWindows() { // obviously will not work because we can't // remove items as we iterate the collection // (the close event removes the window from the collection) OpenedWindows.ForEach( x => x.Close() ); // works fine, but would like to know how to do // this with delegates / events. while( OpenedWindows.Any() ) { OpenedWindows[0].Close(); } } } Specifically, within the CloseAllWindows() method, how could you iterate the collection to call the close event, but defer the event being raised until the collection has been completely iterated?

  • Reference problem when returning an object from array in PHP

    - by avastreg
    I've a reference problem; the example should be more descriptive than me :P I have a class that has an array of objects and retrieve them through a key (string), like an associative array: class Collection { public $elements; function __construct() { $this->elements = array(); } public function get_element($key) { foreach($this->elements as $element) { if ($element->key == $key) { return $element; break; } } return null; } public function add_element ($element) { $this->elements[] = $element; } } Then i have an object (generic), with a key and some variables: class Element { public $key; public $another_var; public function __construct($key) { $this->key = $key; $this->another_var = "default"; } } Now, i create my collection: $collection = new Collection(); $collection->add_element(new Element("test1")); $collection->add_element(new Element("test2")); And then i try to change variable of an element contained in my "array": $element = $collection->get_element("test1"); $element->another_var = "random_string"; echo $collection->get_element("test1")->another_var; Ok, the output is random_string so i know that my object is passed to $element in reference mode. But if i do, instead: $element = $collection-get_element("test1"); $element = null; //or $element = new GenericObject(); $element-another_var = "bla"; echo $collection-get_element("test1")-another_var; the output is default like if it lost the reference. So, what's wrong? I have got the references to the variables of the element and not to the element itself? Any ideas?
