  • php recursive list help

    - by Jason
    Hi all, I am trying to display a recursive list in PHP for a site I am working on. I am really having trouble trying to get the second level to display. I have a function that displays the contents to the page as follows. function get_menu_entries($content,$which=0) { global $tbl_prefix, $sys_explorer_vars, $sys_config_vars; // INIT LIBRARIES $db = new DB_Tpl(); $curr_time = time(); $db->query("SELECT * FROM ".$tbl_prefix."sys_explorer WHERE preid = '".$which."' && config_id = '".$sys_explorer_vars['config_id']."' && blocked = '0' && startdate < '".$curr_time."' && (enddate > '".$curr_time."' || enddate = '') ORDER BY preid,sorting"); while($db->next_record()){ $indent = $db->f("level") * 10 - 10; $sitemap_vars['break'] = ""; $sitemap_vars['bold'] = ""; if($db->f("level") == 2) { $sitemap_vars['ul_start'] = ""; $sitemap_vars['bold'] = "class='bold'"; $sitemap_vars['ul_end'] = ""; } switch($db->f("link_type")) { case '1': // External Url $sitemap_vars['hyperlink'] = $db->f("link_url"); $sitemap_vars['target'] = ""; if($db->f("link_target") != "") { $sitemap_vars['target'] = "target=\"".$db->f("link_target")."\""; } break; case '2': // Shortcut $sitemap_vars['hyperlink'] = create_url($db->f("link_eid"),$db->f("name"),$sys_config_vars['mod_rewrite']); $sitemap_vars['target'] = ""; break; default: $sitemap_vars['hyperlink'] = create_url($db->f("eid"),$db->f("name"),$sys_config_vars['mod_rewrite']); $sitemap_vars['target'] = ""; break; } if($db->f("level") > 1) { $content .= "<div style=\"text-indent: ".$indent."px;\" ".$sitemap_vars['bold']."><a href=\"".$sitemap_vars['hyperlink']."\" ".$sitemap_vars['target'].">".$db->f("name")."</a></div>\n"; } $content = get_menu_entries($content,$db->f("eid")); } return(''.$content.''); } At the moment the content displays properly, however I want to turn this function into a DHTML dropdown menu. At present what happens with the level 2 elements is that using CSS the contents are indented using CSS. What I need to happen is to place the UL tag at the beginning and /UL tag at the end of the level 2 elements. I hope this makes sense. Any help would be greatly appreciated.

  • XMLReader in silverlight <test /> type tag problem

    - by Ummar
    Hi I am parsing XML in silverlight, in my XML I have one tag is like <test attribute1="123" /> <test1 attribute2="345">abc text</test1> I am using XMLReader to parse xml like using (XmlReader reader = XmlReader.Create(new StringReader(xmlString))) { // Parse the file and display each of the nodes. while (reader.Read()) { switch (reader.NodeType) { case XmlNodeType.Element: //process start tag here break; case XmlNodeType.Text: //process text here break; case XmlNodeType.XmlDeclaration: case XmlNodeType.ProcessingInstruction: break; case XmlNodeType.Comment: break; case XmlNodeType.EndElement: //process end tag here break; } } } but the problem is that for test tag no EndElement is received? which is making my whole program logic wrong. (for test1 tag all works fine). Please help me out.

  • How can I get the name of the uploaded file in HTML::Mason?

    - by marghi
    Recently I've been trying to get some files uploaded on to my server in my HTML::Mason application. All good, no problems there. Apparently Mason returns a filehandle directly in the argument. The problem is that I cannot retrieve the filename from that filehandle in a elegant way. One method of resolving this issue is parsing the filename on the client before sending it to the server and placing the extracted value in a hidden field so that it gets sent upon submit. BUT that is very unsafe!

  • Gtk+ Tables for Layout - Good or Bad?

    - by wag2639
    Hi, I'm just starting to play around with GTK+ and I wanted to stop bad habits before they happen. I see that GTK+ seems to be a little based in HTML/CSS and I was wondering if there are any reasons to avoid using tables for layout.

  • hand coding a parser

    - by John Leidegren
    For all you compiler gurus, I wanna write a recursive descent parser and I wanna do it with just code. No generating lexers and parsers from some other grammar and don't tell me to read the dragon book, i'll come around to that eventually. I wanna get into the gritty details about implementing a lexer and parser for a reasonable simple langauge, say CSS. And I wanna do this right. This will probably end up being a series of questions but right now I'm starting with a lexer. Tokenization rules for CSS can be found here. I find my self writing code like this (hopefully you can infer the rest from this snippet): public CssToken ReadNext() { int val; while ((val = _reader.Read()) != -1) { var c = (char)val; switch (_stack.Top) { case ParserState.Init: if (c == ' ') { continue; // ignore } else if (c == '.') { _stack.Transition(ParserState.SubIdent, ParserState.Init); } break; case ParserState.SubIdent: if (c == '-') { _token.Append(c); } _stack.Transition(ParserState.SubNMBegin); break; What is this called? and how far off am I from something reasonable well understood? I'm trying to balence something which is fair in terms of efficiency and easy to work with, using a stack to implement some kind of state machine is working quite well, but I'm unsure how to continue like this. What I have is an input stream, from which I can read 1 character at a time. I don't do any look a head right now, I just read the character then depending on the current state try to do something with that. I'd really like to get into the mind set of writing reusable snippets of code. This Transition method is currently means to do that, it will pop the current state of the stack and then push the arguments in reverse order. That way, when I write Transition(ParserState.SubIdent, ParserState.Init) it will "call" a sub routine SubIdent which will, when complete, return to the Init state. The parser will be implemented in much the same way, currently, having everyhing in a single big method like this allows me to easily return a token when I found one, but it also forces me to keep everything in one single big method. Is there a nice way to split these tokenization rules into seperate methods? Any input/advice on the matter would be greatly appriciated!

  • PHP SoapClient: Problems with Distributed WSDL File

    - by Dave
    Hello, I have a problem using a distributed WSDL File ( scheme / other definitions are declared outside the actual wsdl) with php's SoapClient. This is the Fault Message I get: SOAP-ERROR: Parsing WSDL: 'getSomeInfo' already defined. After some googling , it seems to be a bug inside php as someone else discovered exactly the same problem: http://bugs.php.net/bug.php?id=45282 Has there been any bug fix(es)? Any solution to work around this bug? PS: I think posting a code snippet is senseless, since the invocation of the SoapClient ctor using just the WSDL is the only that fails. Thank you in advance, Dave

  • NSXMLParser rss issue NSXMLParserInvalidCharacterError

    - by Chris Van Buskirk
    NSXMLParserInvalidCharacterError # 9 This is the error I get when I hit a weird character (like quotes copied and pasted from word to the web form, that end up in the feed). The feed I am using is not giving an encoding, and their is no hope for me to get them to change that. This is all I get in the header: < ?xml version="1.0"? < rss version="2.0" What can I do about illegal characters when parsing feeds? Do I sweep the data prior to the parse? Is there something I am missing in the API? Has anyone dealt with this issue?

  • Why is there no code-folding in emacs ?

    - by Pierre
    There are several questions on SO about how to get code folding in emacs, without having to add any special characters like "markers" in the comments for example. Someone said that there was "no perfect solution." It seems that it could be done by parsing the source of the program being written and look for matching parenthesis or bracket, or to do it based on indentation. You could also use a combination of scripts that use different methods. So why is it commonly accepted that there is no "perfect" and straightforward way to get code-folding in emac? Is there something in emacs or its architecture that makes it hard to program? If it were easy, after so many years of smart people using emacs you would think that someone would have wrote it.

  • Loop over DOMDocument

    - by Zoredache
    I am following the suggestion from this question Robust, Mature HTML Parser for PHP, about parsing html that may be malformed with DOMDocument. Is there any easy way to loop over the parsed document? So I would like to loop over html like this. $html='<ul> <li>value1</li> <li>value1</li> <li>value3</li> </ul> <p>hello world</p>'; $doc = new DOMDocument(); $doc->loadHTML($html); ??? foreach (??? as $node) { print $node->nodeName.':'.$node->nodeValue; } And get results somewhat like this. ul: li:value1 li:value2 li:value3 p:hello world

  • jaxb XmlAccessType: PROPERTY example

    - by Bjorn J
    I'm trying to use jaxb and want to use the 'XmlAccessType.PROPERTY' to let jaxb use getters/setters rather than variable directly, but get different errors depending on what I try, or the variable isn't set at all like I want. Any good link or pointer to a simple example? For example, the below makes the groupDefintion not to be set when parsing the xml document: @XmlAccessorType(javax.xml.bind.annotation.XmlAccessType.PROPERTY) public class E { private EGroup groupDefinition; public EGroup getGroupDefinition () { return groupDefinition; } @XmlAttribute public void setGroupDefinition (EGroup g) { groupDefinition = g; } }

    Is there a way to just have something "show"? I know there's the effect called show, but I mean something with no animation. I know I could make the speed way fast or something. Or I could change the css from hidden or something. But does someone know of a built in method that does that? Same with "hide".

    I'm trying to define a step to test the value of alt text of an image using capybara and the css selectors. I wrote one for input values based on the readme examples: Then /^I should see a value of "([^\"])" within the "([^\"])" input$/ do |input_value, input_id| element_value = locate("input##{input_id}").value element_value.should == input_value end But I can't figure this one out...something like: Then /^I should see the alttext "([^\"]*)"$/ do | alt_text | element_value = locate("img[alt]").value Anyone know how I can locate the alt text value?

  • In Haskell, will calling length on a Lazy ByteString force the entire string into memory?

    - by me2
    I am reading a large data stream using lazy bytestrings, and want to know if at least X more bytes is available while parsing it. That is, I want to know if the bytestring is at least X bytes long. Will calling length on it result in the entire stream getting loaded, hence defeating the purpose of using the lazy bytestring? If yes, then the followup would be: How to tell if it has at least X bytes without loading the entire stream? EDIT: Originally I asked in the context of reading files but understand that there are better ways to determine filesize. Te ultimate solution I need however should not depend on the lazy bytestring source.

Features I'd like - Code Completion I'm also interested in any comments in general about coding on a Mac and if it's really worth the extra $$$ to get one. Thanks
