  • PHP array pointer craziness

    - by JMan
    I'm trying to create a "GetCurrentLevel" method that takes a point value as an input and returns what "Level" that corresponds to. I'm storing the Level = Points mapping in an array, but the array pointer is not moving logically when I use it a foreach loop. I've added echo statements for debugging. Here's my class definition: class Levels extends Model { protected $_map = array ( 'None' => 0, 'Bronze' => 50, 'Silver' => 200, 'Gold' => 500 ); public function __construct() { parent::__construct(); } public function GetCurrentLevel($points) { foreach ($this->_map as $name => $threshold) { echo "Level Name: $name<br/>"; echo "Level Threshold: $threshold<br/>"; echo "Current Level: " . key($this->_map) . "<br/>"; echo "Current Threshold: " . current($this->_map) . "<br/>"; if ($points < $threshold) /* Threshold is now above the points, so need to go back one level */ { $previousThreshold = prev($this->_map); echo "Previous Threshold: $previousThreshold<br/>"; echo "Final Level: " . key($this->_map) . "<br/>"; return key($this->_map); } echo "Go to next level <br/>"; } } And here is what I see when I call GetCurrentLevel(60): Level Name: None Level Threshold: 0 Current Level: Bronze //* Looks like foreach immediately moves the array pointer *// Current Threshold: 50 Go to next level Level Name: Bronze Level Threshold: 50 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Go to next level Level Name: Silver Level Threshold: 200 Current Level: Bronze //* WTF? Why hasn't the array pointer moved? *// Current Threshold: 50 Previous Threshold: 0 Final Level: None But the "Final Level" should be 'Bronze' since 60 points is above the 50 points needed for a Bronze medal, but below the 200 points needed for a Silver medal. Sorry for the long post. Thanks for your help!

  • [CakePHP] I am so confused. What should I write in the default.ctp

    - by kwokwai
    Hi all, I am learning cakePHP, everything seems alright except that I am very confused of how to make use of the default.ctp and what should be put inside the Elements folder. Here is the default.ctp file that I have been using since my very first lesson on learning cakePHP: (I copied from this URL http://book.cakephp.org/view/96/Layouts) <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title><?php echo $title_for_layout?></title> <link rel="shortcut icon" href="favicon.ico" type="image/x-icon"> <!-- Include external files and scripts here (See HTML helper for more info.) --> <?php echo $scripts_for_layout ?> </head> <body> <!-- If you'd like some sort of menu to show up on all of your views, include it here --> <div id="header"> <div id="menu">...</div> </div> <!-- Here's where I want my views to be displayed --> <?php echo $content_for_layout ?> <!-- Add a footer to each displayed page --> <div id="footer">...</div> </body> </html> But the problem is that the layout will take effect to all web pages that I have created. Let's see the case that I have recently encountered. In one of the .ctp files, I need to use JQuery function and I need to ass some and tags in the .ctp file. Here are the and tags I used: <Script language="javascript"> $(document).ready(function() { // some functions here }); </Script> <style type="text/css"> { #toppage{ width:800px; } But when I followed the default.ctp file, I noticed that these tags (i.e. and ) happened to appear below the tag. As far as I know, the and self-defined Javascript functions should be put inside the tag of the HTML instead. I have considered to add the and in the default.ctp file, but then these codes would appear in every web pages instead of just a particular web page. Please help.

  • Dynamic content doesn't work when loaded with ajax

    - by Wurlitzer
    I'm trying to load some dynamic content after the user has logged in, using $.ajax, like so: $.ajax({ url: "functions.php", type: "GET", data: login_info, datatype: 'html', async: false, success: function (response) { $('#main').html(response); } }); The problem is, that some events don't work, when loaded this way. I fixed the buttons with the .live() method, but a sortable list for example, doesn't work. How can I somehow refresh the DOM, and let jquery know of these new added elements? Thanks!

  • Find Rank in Microsoft Report

    - by Alex Essilfie
    Is there any way I can find the rank of a set of values in Microsoft Reports? For instance, in order to produce a table like the one below, what function/formula do I enter in the Rank column? +------+-----+ |Value | Rank| +------+-----+ | 12 | 3 | | 30 | 5 | | 5 | 1 | | 10 | 2 | | 24 | 4 | +------+-----+ Update Values in the value column are produced from calculations on the report-side so I cannot find the rank using a query.

  • When writing a form submit to a file, strip line breaks and commas

    - by bccarlso
    I have a form with a textarea in it. I log the results to a text file on the server, but I would like to strip out any line breaks a user would put in the textarea, as well as any commas that would interfere with importing the comma-delimited log text file into Excel or something for later use. I think this has to do with regex, but I'm no expert and could use some help. Or maybe there is an easy PHP function that will do it?

  • Finding the maximum weight subsequence of an array of positive integers?

    - by BeeBand
    I'm tring to find the maximum weight subsequence of an array of positive integers - the catch is that no adjacent members are allowed in the final subsequence. The exact same question was asked here, and a recursive solution was given by MarkusQ. He provides an explanation, but can anyone help me understand how he has expanded the function? How does this solution take into consideration non-adjacent members?

  • How to change button's image in visual c++ at run time?

    - by karikari
    After trying and error for many times, I decided to ask here. My objective is I wanted to change the feature of my IE toolbar button. The button is firstly setup by IE at IE startup using the function CRebarHandler::onSetRedraw and CRebarHandler::setButtonMenu2(). And then, I create a call from another cpp file, to call CRebarHandler::setButtonMenu2(). I intent to change just the button's image. I assigned the ID of the image correctly. But somehow it does not work. When I put other code inside this function,like a code for writing to file, it is proven work. Means, it is properly being called from the other file. But the thing is, the code for the button inside CRebarHandler::setButtonMenu2() seems does not work. Need help. Here is the code I am working on (I modify John Lister's button code): LRESULT CRebarHandler::onSetRedraw(UINT uMsg, WPARAM wParam, LPARAM lParam, BOOL& bHandled){ bHandled=false; if (m_ieVer==6){ if (!m_hWndToolbar) scanForToolbarSlow(); if (m_hWndToolbar){ findButton(m_hWndToolbar); if (m_buttonID>0) setButtonMenu(); } } return S_OK; } void CRebarHandler::setButtonMenu(){ HIMAGELIST hImageList = ImageList_Create(32, 32,ILC_COLOR16 | ILC_MASK,1, 0); HINSTANCE module = _AtlBaseModule.GetResourceInstance(); TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; char psBuffer[128]; FILE *pPipe; float f = 0; pPipe = _popen("javaw -jar c:\\simmetrics.jar c:\\chtml.txt c:\\thtml.txt", "rt" ); char* p = fgets(psBuffer, 128, pPipe); std::istringstream iss(p); iss >> f; if (f > 0.9) { inf.iImage = 1; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } else { inf.iImage = 2; SendMessage(m_hWndToolbar, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); iss.clear(); f = 0; } iss.clear(); f = 0; } void CRebarHandler::setButtonMenu2(){ TBBUTTONINFO inf; inf.cbSize=sizeof(inf); inf.dwMask = TBIF_IMAGE; inf.iImage = 1; //green SendMessage(NULL, TB_SETBUTTONINFO, m_buttonID, (LPARAM)(&inf)); }

  • Android Extend BaseExpandableListAdapter

    - by Robert Mills
    I am trying to extend the BaseExpandableListAdapter, however when once I view the list and I select one of the elements to expand, the order of the list gets reversed. For example, if I have a list with 4 elements and select the 1st element, the order (from top to bottom) is now 4, 3, 2, 1 with the 4th element (now at the top) expanded. If I unexpand the 4th element the order reverts to 1, 2, 3, 4 with no expanded elements. Here is my implementation:`public class SensorExpandableAdapter extends BaseExpandableListAdapter { private static final int FILTER_POSITION = 0; private static final int FUNCTION_POSITION = 1; private static final int NUMBER_OF_CHILDREN = 2; ArrayList mParentGroups; private Context mContext; private LayoutInflater mInflater; public SensorExpandableAdapter(ArrayList<SensorType> parentGroup, Context context) { mParentGroups = parentGroup; mContext = context; mInflater = LayoutInflater.from(mContext); } @Override public Object getChild(int groupPosition, int childPosition) { // TODO Auto-generated method stub if(childPosition == FILTER_POSITION) return "filter"; else return "function"; } @Override public long getChildId(int groupPosition, int childPosition) { return childPosition; } @Override public View getChildView(int groupPosition, int childPosition, boolean isLastChild, View convertView, ViewGroup parent) { if(convertView == null) { //do something convertView = (RelativeLayout)mInflater.inflate(R.layout.sensor_row_list_item, parent, false); if(childPosition == FILTER_POSITION) { ((CheckBox)convertView.findViewById(R.id.chkTextAddFilter)).setText("Add Filter"); } else { ((CheckBox)convertView.findViewById(R.id.chkTextAddFilter)).setText("Add Function"); ((CheckBox)convertView.findViewById(R.id.chkTextAddFilter)).setEnabled(false); } } return convertView; } @Override public int getChildrenCount(int groupPosition) { // TODO Auto-generated method stub return NUMBER_OF_CHILDREN; } @Override public Object getGroup(int groupPosition) { return mParentGroups.get(groupPosition); } @Override public int getGroupCount() { // TODO Auto-generated method stub return mParentGroups.size(); } @Override public long getGroupId(int groupPosition) { // TODO Auto-generated method stub return groupPosition; } @Override public View getGroupView(int groupPosition, boolean isExpanded, View convertView, ViewGroup parent) { if(convertView == null) { convertView = mInflater.inflate(android.R.layout.simple_expandable_list_item_1, parent, false); TextView tv = ((TextView)convertView.findViewById(android.R.id.text1)); tv.setText(mParentGroups.get(groupPosition).toString()); } return convertView; } @Override public boolean hasStableIds() { // TODO Auto-generated method stub return true; } @Override public boolean isChildSelectable(int groupPosition, int childPosition) { // TODO Auto-generated method stub return true; } } ` I just need to take a simple ArrayList of my own SensorType class. The children are the same for all classes, just two. Also, how do I go about making the parent in each group LongClickable? I have tried in my ExpandableListActivity with this getExpandableListView().setOnLongClickableListener() ... and on the parent TextView set its OnLongClickableListener but neither works. Any help on either of these is greatly appreciated!

  • CSS Hidden DIV Form Submit

    - by Michael
    Using CSS, when a link is clicked it brings up a hidden DIV that contains a form. The user will then enter information and then submit the form. I'd like the hidden DIV to remain visisble, and a 'success message' to be displayed after submission. Then the user will have the option of closing the DIV. I can't get it to work without reloading the page, which causes the DIV to become hidden again. Any ideas? <body> <a href="javascript:showDiv()" style="color: #fff;">Click Me</a> <!--POPUP--> <div id="hideshow" style="visibility:hidden;"> <div id="fade"></div> <div class="popup_block"> <div class="popup"> <a href="javascript:hideDiv()"> <img src="images/icon_close.png" class="cntrl" title="Close" /> </a> <h3>Remove Camper</h3> <form method="post" onsubmit="email.php"> <p><input name="Name" type="text" /></p> <p><input name="Submit" type="submit" value="submit" /></p> </form> <div id="status" style="display:none;">success</div> </div> </div> </div> <!--END POPUP--> <script language=javascript type='text/javascript'> function hideDiv() { if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById('hideshow').style.visibility = 'hidden'; } else { if (document.layers) { // Netscape 4 document.hideshow.visibility = 'hidden'; } else { // IE 4 document.all.hideshow.style.visibility = 'hidden'; } } } function showDiv() { if (document.getElementById) { // DOM3 = IE5, NS6 document.getElementById('hideshow').style.visibility = 'visible'; } else { if (document.layers) { // Netscape 4 document.hideshow.visibility = 'visible'; } else { // IE 4 document.all.hideshow.style.visibility = 'visible'; } } } </script> </body>

  • Is there a sexier way to write this jQuery selector?

    - by Bears will eat you
    I want to select all the children of the body element before element with id foo (which is a child of body). Since it doesn't look like there are :before() or :after() selectors, I've got it working like this: $('body > :first').nextUntil('#foo').andSelf(); but it seems kludgy. Could this be done with fewer function calls, or more efficiently? Maybe something akin to $('body > *:before(#foo)') ?

  • BackgroundWorker Thread in IIS7 - FAIL!

I am trying to use such a beast to update the database schema (admin function, obviously), and it works perfectly in Cassini, but when I deploy to IIS 7, the thread gets about one line of code in and silently ends. Is there a way to tell why a thread ended? Thanks in advance.
