• Minimum 4 Characters or Show Nothing - PHP

  - by ali

  Hi, I want to show up only words with minimum 4 Characters, actually I can limit the hits and show only words with min. 100 hits - but how can I set a min. character length? thank you! function sm_list_recent_searches($before = '', $after = '', $count = 20) { // List the most recent successful searches. global $wpdb, $table_prefix; $count = intval($count); $results = $wpdb->get_results( "SELECT `terms`, `datetime` FROM `{$table_prefix}searchmeter_recent` WHERE 100 < `hits` ORDER BY `datetime` DESC LIMIT $count"); if (count($results)) { foreach ($results as $result) { echo '<a href="'. get_settings('home') .

• Checking if a string's characters are ascending alphabetically and its ascent is evenly spaced python

  - by FRU5TR8EDD

  So need to check if a string's characters are ascending alphabetically and if that ascent is evenly spaced. a = "abc" b = "ceg" So a is alphabetically ascending and it's spacing is 1 (if you convert to the ordinal values they are 97,98,99). And b is also alphabetically ascending and it's spacing is 2 (99,101,103). And I am sticking with the following code: a = 'jubjub' words1 = [] ords = [ord(letter) for letter in a] diff = ords[1] - ords[0] for ord_val in range(1, len(ords)-1): if diff > 0: if ords[ord_val + 1] - ords[ord_val] == diff: if a not in words1: words1.append((a, diff)) print words1 How come 'jubjub' works, 'ace' works, but 'catcat' doesn't?

• Alt attribute encoding with JavaScript

  - by MainMa

  Hi, Html entities must be encoded in alt attribute of an image in HTML page. So <img id="formula" alt="A &rarr; B" src="formula.png" /> will work well. On the other hand, the same JavaScript code will not work document.getElementById('formula').alt = 'A &rarr; B'; and will produce A &rarr; B instead of A → B. How to do it through JavaScript, when it is not possible to put the special (unencoded) characters in the source code?

• file_get_contents() removing tab and new line characters

  - by Patrick Murray

  I am having an issue today with the file_get_contents() function. When reading large files, the newline and tab characters are often removed. Here is a minified example of how I am using this. I hope I am not the only one who has encountered this issue! :O Thank you for your time! <?php $file_name = "template.html"; $data = array( 'title' => 'Hello, World!', 'content'=> 'Hey stackoverflow!'); $file_contents = file_get_contents($file_name); foreach($data as $comment_name => $replacement_value){ $search = "<!-- ".strtoupper($comment_name)." -->"; $file_contents = str_replace($search, $replacement_value, $file_contents); } echo $file_contents; ?>

  I'm trying to write some .htaccess rules that replace certain characters in the REQUEST_URI parameter.

• C# Console Application - Odd behaviour - char '\a'

  - by KHT

  After extensive debugging of an application, I noticed the console window would hang when searching text for the char '\a'. The goal is to strip out characters from a file. The console window would always hang upon exiting the program, and it would make it to the last statement of main. I removed the '\a' from the switch statement and the console application does not hang anymore. Any idea why? I still need to strip out the char '\a', but cannot get the application to work without hanging. switch (c) { case '\t': //Horizontal Tab case '\v': //Vertical Tab case '\n': //Newline case '\f': //Form feed case '\r': //carriage return case '\b': //Backspace case '\x7f': //delete character case '\x99': //TM Trademark case '\a': //Bell Alert **REMOVED THIS** return true; }

• css to replace characters in paragraph tag

  - by Thariama

  Already checked exisitng questions for this, but didn't find an exact match. My aim is to replace characters (like spaces) on a webpage with a small image using css. Example: <p><span>This is a text</span></p> becomes: <p><span>ThisIMGisIMGaIMGtext</span></p> (where IMG stands for a visible image (middot-pic for a space f.e.)) I cannot think of a suitable css selector. But myabe one of you guys (or girls) know a solution. Is this possible at all?

• formatting european characters from JSON results

  - by mlecho

  hi, i am building an application that imports JSON results and parses the objects to a table cell. Nothing fancy, but in my results, many of the terms/names are European with characters such as è or ú which come out as \u00E9 or \u00FA. I think these are ASCII ? or unicode? ( i can never keep em staight). Anyway, like all good NSSTring's, i figured there must be a method to fix this, but i am not finding it....any ideas? I am trying to avoid doing something like this: this posting. Thanks all.

• Wierd characters in exported csv files when converting

  - by Ahue

  Hey guys, I came across a problem I cannot solve on my own concerning the downloadable csv formatted trends data files from Google Insights for Search. I'm to lazy to reformat the files I4S gives me manually what means: Extracting the section with the actual trends data and reformatting the columns so that I can use it with a modelling program I do for school. So I wrote a tiny script the should do the work for me: Taking a file, do some magic and give me a new file in proper format. What it's supposed to do is reading the file contents, extracting the trends section, splitting it by newlines, splitting each line and then reorder the columns and maybe reformat them. When looking at a untouched I4S csv file it looks normal containing CR LF caracters at line breaks (maybe thats only because I'm using Windows). When just reading the contents and then writing them to a new file using the script wierd asian characters appear between CR and LF. I tried the script with a manually written similar looking file and even tried a csv file from Google Trends and it works fine. I use Python and the script (snippet) I used for the following example looks like this: # Read from an input file file = open(file,"r") contents = file.read() file.close() cfile = open("m.log","w+") cfile.write(contents) cfile.close() Has anybody an idea why those characters appear??? Thank you for you help! I'll give you and example: First few lines of I4S csv file: Web Search Interest: foobar Worldwide; 2004 - present Interest over time Week foobar 2004-01-04 - 2004-01-10 44 2004-01-11 - 2004-01-17 44 2004-01-18 - 2004-01-24 37 2004-01-25 - 2004-01-31 40 2004-02-01 - 2004-02-07 49 2004-02-08 - 2004-02-14 51 2004-02-15 - 2004-02-21 45 2004-02-22 - 2004-02-28 61 2004-02-29 - 2004-03-06 51 2004-03-07 - 2004-03-13 48 2004-03-14 - 2004-03-20 50 2004-03-21 - 2004-03-27 56 2004-03-28 - 2004-04-03 59 Output file when reading and writing contents: Web Search Interest: foobar ??????????? ? ? ? ????????? ????????? ???? ??????

• Removing control / special characters from log file

  - by digitalsky

  I have a log file captured by tclsh which captures all the backspace characters (ctrl-H, shows up as "^H") and color-setting sequences (eg. ^[[32m .... ^[[0m ). What is an efficient way to remove them? ^[...m This one is easy since, I can just do "sed -i /^[.*m//g" to remove them ^H Right now I have "sed -i s/.^H//", which "applies" a backspace, but I have to keep looping this until there are no more backspaces. while [ logfile == `grep -l ^H logfile` ]; do sed -i s/.^H// logfile ; done; "sed -i s/.^H//g" doesn't work because it would match consecutive backspaces. This process takes 11 mins for my log file with ~6k lines, which is too long. Any better ways to remove the backspace?

• Insert unicode strings into CleverCSS

  - by Brian M. Hunt

  How can one insert a Unicode string CSS into CleverCSS? In particular, how could one produce the following CSS using CleverCSS: li:after { content: "\00BB \0020"; } I've figured out CleverCSS's parsing rules, but suffice that the permutations I've thought sensible have failed, for example: li: content: "\\00BB \\0020" // becomes content: 'BB 0' EDIT: My other examples and the rest of my post weren't saved. Suffice that I had a longer list of examples that also failed, as did my closing which was something like: I'd be grateful for any thoughts and input. Brian

• Convert XMLDocument to String

  - by mnh

  Here is how I'm currently converting XMLDocument to String StringWriter stringWriter = new StringWriter(); XmlTextWriter xmlTextWriter = new XmlTextWriter(stringWriter); xmlDoc.WriteTo(xmlTextWriter); return stringWriter.ToString(); The problem with this method is that if I have " ((quotes) which I have in attributes) it escapes them. For Instance: <Campaign name="ABC"> </Campaign> Above is the expected XML. But it returns <Campaign name=\"ABC\"> </Campaign> I can do String.Replace "\" but is that method okay? Are there any side-effects? Will it work fine if the XML itself contains a "\"

• URLScan and percent signs

  - by Hobbes

  So I just ran into a stupid problem in which users could not download files that had a percent sign in it. It wound up being URLScan. I had to un-set two things in urlscan.ini: 1) Set VerifyNormalization to 0 (disabled) 2) Remove the percent sign from the "DenyUrlSequences" section Do an iisreset, and it problem solved. But the big question is: How much of a security risk is this?

• Escaping single quote in PHP when inserting into MySQL

  - by hairdresser-101

  I have a perplexing issue that I can't seem to comprehend... I'm hoping someone here might be able to point me in the right direction... I have two SQL statements: - the first enters information from a form into the database. - the second takes data from the database entered above, sends an email and then logs the details of the transaction The problem is that it a appears that a single quote is triggering a MySQL error on the second entry only!!! The first instance works without issue but the second instance triggers the mysql_error(). Does the data from a form get handled differently from the data captured in a form? Query#1 - This works without issue (and without escaping the single quote) $result = mysql_query("INSERT INTO job_log (order_id, supplier_id, category_id, service_id, qty_ordered, customer_id, user_id, salesperson_ref, booking_ref, booking_name, address, suburb, postcode, state_id, region_id, email, phone, phone2, mobile, delivery_date, stock_taken, special_instructions, cost_price, cost_price_gst, sell_price, sell_price_gst, ext_sell_price, retail_customer, created, modified, log_status_id) VALUES ('$order_id', '$supplier_id', '$category_id', '{$value['id']}', '{$value['qty']}', '$customer_id', '$user_id', '$salesperson_ref', '$booking_ref', '$booking_name', '$address', '$suburb', '$postcode', '$state_id', '$region_id', '$email', '$phone', '$phone2', '$mobile', STR_TO_DATE('$delivery_date', '%d/%m/%Y'), '$stock_taken', '$special_instructions', '$cost_price', '$cost_price_gst', '$sell_price', '$sell_price_gst', '$ext_sell_price', '$retail_customer', '".date('Y-m-d H:i:s', time())."', '".date('Y-m-d H:i:s', time())."', '1')"); Query#2 - This fails when entering a name with a single quote (i.e. O'Brien) $query = mysql_query("INSERT INTO message_log (order_id, timestamp, message_type, email_from, supplier_id, primary_contact, secondary_contact, subject, message_content, status) VALUES ('$order_id', '".date('Y-m-d H:i:s', time())."', '$email', '$from', '$row->supplier_id', '$row->primary_email' ,'$row->secondary_email', '$subject', '$message_content', '1')");

• Why can I not view foreign language characters in my mysql DB?

  I am inserting the following characters into my DB: ?? / ?? This is the meta tag on the page that is inserting the characters: <meta http-equiv="Content-Type" content="text/html; charset=UTF-8" /> I have altered all the columns in my table that is holding the characters to be utf8_unicode_ci The foreign characters show up like so in the DB: 汉字 / 漢字 When I use a sql statement to display those foreign characters on a page, they display correctly again as: ?? / ?? I am guessing I have some setting that is not correct in my DB, since it stores it correctly, but does not display it correctly. What can i do to make the foreign language characters to display correctly in my DB?

• Dollar ($) sign in password string treated as variable

  - by ncatnow

  Spent some time troubleshooting a problem whereby a PHP/MySQL web application was having problems connecting to the database. The database could be accessed from the shell and phpMyAdmin with the exact same credentials and it didn't make sense. Turns out the password had a $ sign in it: $_DB["password"] = "mypas$word"; The password being sent was "mypas" which is obviously wrong. What's the best way to handle this problem? I escaped the $ with a \ $_DB["password"] = "mypas\$word"; and it worked. I generally use $string = 'test' for strings which is probably how I avoided running into this before. Is this correct behavious? What if this password was stored in a database and PHP pulled it out - would this same problem occur? What am I missing here...

• Ruby -- looking for some sort of "Regexp unescape" method

  - by RubyNoobie

  I have a bunch of strings that appear to have been double-escaped -- eg, I have "\\014\"\\000\"\\016smoothing\"\\011mean\"\\022color\"\\011zero@\\016" but I want "\014"\000"\016smoothing"\011mean"\022color"\011zero@\016" Is there a method I can use to unescape them? I imagine that I could make a regex to remove 1 backslash from every consecutive n backslashes, but I don't have a lot of regex experience and it seems there ought to be a "more elegant" way to do it. For example, when I puts MyString it displays the output I'd like, but I don't know how I might capture that into a variable. Thanks! Edited to add context: I have this class that is being used to marshal / restore some stuff, but when I restore some old strings it spits out a type error which I've determined is because they weren't -- for some inexplicable reason -- stored as base64. They instead appear to be 'double-escaped', when I need them to be 'single-escaped' to get restored. require 'base64' class MarshaledStuff < ActiveRecord::Base validates_presence_of :marshaled_obj def contents obj = self.marshaled_obj return Marshal.restore(Base64.decode64(obj)) end def contents=(newcontents) self.marshaled_obj = Base64.encode64(Marshal.dump(newcontents)) end end

• What regular expression do I need to check for some non-latin characters?

  - by zeckdude

  I am checking a field if it is Latin Characters or not. var foreignCharacters = $("#foreign_characters").val(); var rlatins = /[\u0000-\u007f]/; if (rlatins.test(foreignCharacters)) { alert("This is Latin Characters"); } else { alert("This is non-latin Characters"); } This works well, but I would like to change it so when I enter any non-latin characters, such as chinese characters, along with a space(which is within that range I am using currently) it will still say it is non-latin characters. How can I change the regular expression I have to do that?

• Decoding mysql_real_escape_string() for outputting HTML

How do I "decode" this back into correctly formatted HTML, with something like: html_entity_decode(stripslashes($string));

• windows C system call with spaces in command

  - by myforwik

  I cannot make system calls with spaces in the names and parameters. For example: system("c:\program files\something\example.exe c:\my files\example.txt"); I have tried escaping in every way I know how, and NOTHING works. I have tried: system("\"c:\program files\something\example.exe\" \"c:\my files\example.txt\""); and system("c:\program^ files\something\example.exe c:\my^ files\example.txt"); Neither work. I still get 'c:\program' is not a recongnised internal or external command This is really driving me mad... I need to call and pass parameters that have spaces in them. I cannot use the short notation for reasons I won't go into. I have tried with ' quotes instead of " quotes, still doesn't work. I have tried putting quotes around the whole thing and quotes around the spaces and that doesn't work. Does anyone know how to do it properly?
