• Unbind Events with JQuery: Does it work with events setup in HTML?

  - by Abs

  Hello all, I have a few onclick and on mouseover events in my html generated by PHP, something like this: <div onmouseover="fave('heart_<?php echo $row['id']; ?>';" class="heart"><a href=""></a></div> I wish to make use of unbind on the mouseover but it hasn't worked when I tried this: $('#'+ id).unbind('mouseover'); So I am guessing unbind will only work with events created by JQuery? Is there something else I can try? Btw, I can't move my events to a separate js file as each id is unique and. Thanks all

• Cakephp: Extend search capability to hasMany Relationship

  - by Chris

  I have two models: Car hasMany Passengers Passenger belongsTo Car I want to implement a search using Cake Search. The user should input a number and the searchengine should return all cars that have less than this number passengers. In my search form: echo $form->input('passengers', array('label' => 'Passengers', 'div' => false)); In my Car model: public $filterArgs = array( array('name' => 'passengers', 'type' => 'int'), ); In the controller: public $presetVars = array( array('field' => 'passengers', 'type' => 'int') } I thought of adding a function to the model that returns the number of passengers: function countPassengers(){ return(count($this->Car->Passenger)); //Not sure if this works } And how to I implement this search criteria?: return all Cars where countPassengers()<passenger

• PHP form validation submit problem?

  - by TaG

  My code is suppose to save a year like 1999 to the mysql database but it wont. It will check to see if the user has entered only numbers and is at least 4 numbers long or if nothing has been entered correctly but it wont save the correct year? How can I fix this problem. Here is the PHP code. if(isset($_POST['year']) && intval($_POST['year']) && strlen($_POST['year']) == 4) { $year = mysqli_real_escape_string($mysqli, $purifier->purify(htmlentities(strip_tags($_POST['year'])))); } else if($_POST['year'] && strlen($_POST['year']) < 4) { echo '<p class="error">year is not correct!</p>'; } else if($_POST['year'] == NULL) { // do something }

• What does $this generally mean in PHP?

  - by xczzhh

  I am really new to PHP, so I am kind of confused seeing these different operators all day. Here is some code I came across when watching a video tutorail, I'd appreciate it if some could explain a little bit: function index() { $config = Array( 'protocol' => 'smtp', 'smtp_host' => 'ssl://smtp.googlemail.com', 'smtp_port' => 465, 'smtp_user' => '[email protected]', 'smtp_pass' =>'password', ); $this->load->library('email', $config); $this->email->set_newline("\r\n"); $this->email->from('[email protected]', 'Jerry'); $this->email->to('[email protected]'); $this->email->subject('this is an email test'); $this->email->message('this is test message!'); if($this->email->send()) { echo 'Your email was sent'; } else { show_error($this->email->print_debugger()); } } ...

• Problems with system() calls in Linux

  - by Thomas

  I'm working on a init for an initramfs in C++ for Linux. This script is used to unlock the DM-Crypt w/ LUKS encrypted drive, and set the LVM drives to be available. Since I don't want to have to reimplement the functionality of cryptsetup and gpg I am using system calls to call the executables. Using a system call to call gpg works fine if I have the system fully brought up already (I already have a bash script based initramfs that works fine in bringing it up, and I use grub to edit the command line to bring it up using the old initramfs). However, in the initramfs it never even acts like it gets called. Even commands like system("echo BLAH"); fail. So, does anyone have any input?

• How to display mysql records as preselected checkboxes?

  - by Jennifer

  I have a table column called post_tags within a table called posts where assigned tags are stored separated by the @ symbol. I also have a table called tags where all tag names are stored. I would like to design my database in a more normalized way but for the purpose I am trying to achieve this is the easiest option. Anyway, I want to display on the screen all the entries from the tags table as checkboxes, so I do: $query = mysql_query("SELECT * FROM tags ORDER BY name"); while ($row = mysql_fetch_assoc($query)) { $tag = $row['name']; echo "<input type='checkbox' name='tags[]' value='$tag' />\n"; } Next I want to have the tags that are assigned to a particular post be preselected. For example, if I have a post with the following in it's post_tags column: party@beaches@dolphins@ I want the "party", "beaches" and "dolphin" checkboxes to be checked by default (while the checkboxes for the other options are unchecked). How can this be done?

• Random password variable disappears

  - by snaken

  Hi, I'm using the following to generate a random password in a shell script: DBPASS=</dev/urandom tr -dc A-Za-z0-9| (head -c $1 > /dev/null 2>&1 || head -c 8) When i run this in a file on its own like this: #!/bin/sh DBPASS=</dev/urandom tr -dc A-Za-z0-9| (head -c $1 > /dev/null 2>&1 || head -c 8) echo $DBPASS A password is echoed. When i incorporate it into a larger script though the variable never seems to get created for some reason, so for example this doesn't work: DBPASS=</dev/urandom tr -dc A-Za-z0-9| (head -c $1 > /dev/null 2>&1 || head -c 8) sed -i s/oldpass/$DBPASS/ mysql_connect.php If i manually set the variable though everything is fine.. can anyone see why?

• Querying associated images in one table after querying products from another

  - by Andy

  I used this code to connect to a database and fetch results. This worked perfectly until i tried to work in another query to the images table to get associated images. I'm not very experienced with OO programming. So hopefully someone can see where ive gone wrong and help me out. <?php global $__CMS_CONN__; $sql = "SELECT * FROM ecom_products"; $stmt = $__CMS_CONN__->prepare($sql); $stmt->execute(array($id)); while ($row = $stmt->fetchObject()) { $imagesql = "SELECT * FROM ecom_product_images where id = $row->id && where primaryImage = '1'"; $imagestmt = $__CMS_CONN__->prepare($sql); $imagestmt->execute(array($id)); $imageName = $imagestmt->fetchObject(); echo '<a href="'.URL_PUBLIC.$row->id.'">'.$row->productNm.'</a>'.$imageName; } ?>

• gitk without X11 [closed]

  - by svnpenn

  It has been noted here that Tcl/Tk, and in turn gitk now require X11 under Cygwin. Having run it before and after this change it seems like extreme overkill. I use gitk very lightly, mostly sticking to simply command line git. How could I go about using gitk without X11, perhaps manually installing old version of Tcl/Tk? After some tinkering, I came up with this script that allows gitk without X11 #!/bin/sh # Requires Cygwin packages: git, make, mingw64-i686-gcc-core, wget # Install Tcl wget prdownloads.sf.net/tcl/tcl8.5.12-src.tar.gz tar xf tcl8.5.12-src.tar.gz cd tcl8.5.12/win ./configure --host i686-w64-mingw32 make install cd - # Install Tk wget prdownloads.sf.net/tcl/tk8.5.12-src.tar.gz tar xf tk8.5.12-src.tar.gz cd tk8.5.12/win ./configure --host i686-w64-mingw32 make install cd - # Install gitk cd /usr/local/bin wget raw.github.com/git/git/master/gitk-git/gitk chmod 700 gitk echo 'cygpath -m "$1" | xargs -I% wish85 % -- ${@:3}' > wish cd -

• Optimizing PHP code (trying to determine min/max/between case)

  I know this code-bit does not conform very much to best coding practices, and was looking to improve it, any ideas? if ($query['date_min'] != _get_date_today()) $mode_min = true; if ($query['date_max'] != _get_date_today()) $mode_max = true; if ($mode_max && $mode_min) $mode = "between"; elseif ($mode_max && !$mode_min) $mode = "max"; elseif (!$mode_max && $mode_min) $mode = "min"; else return; if ($mode == "min" || $mode == "between") { $command_min = "A"; } if ($mode == "max" || $mode == "between") { $command_max = "B"; } if ($mode == "between") { $command = $command_min .

• Remembering Form information

  - by Pete Herbert Penito

  Hi everyone! I'm sorry if this has been asked before but I feel my situation is a little different... I have a huge form (like 50 questions involving checkboxes, drop downs, text boxes and textareas) When a user submits a form and the validation page throws an error, is there an easy way to keep the info they entered? My intitial form is on form.php and then the form action is form_posted.php, before anything is run on form_posted.php I have my validation code which sends the user back to form.php with an error number (eg. form.php?error=3) if there was a problem with any in particular. This is done with header("form.php?error=3") so on form.php do the posted variables exist? even tho the page wasn't specifically sent with any posted variables. Also if this is the case, is it completely secure to be making the value of a textbox what it was before? like <input type="text" value="php echo $_POSTED["username"] ?>">

• Inconsistent Session data from IE - cached sessions???

  - by pedalpete

  I'm trying to prevent some basic click-fraud on my site, and am building links based on session time data. Everything works in FF, but in IE the information I'm storing in the session is somehow being changed. When I load up the main page, I set my session variables like this session_start(); $_SESSION['time']=$time(); I'm out putting the session value into the page, so I get something like 1275512393. When the user clicks on a link, I send an ajax request, and that page is returning the session which I am putting into an alert. session_start(); echo $_SESSION['time']; die(); The alert is returning 1275512422. Only in IE is the $_SESSION['time'] being returned different from the original $_SESSION['time'] It doesn't appear that this is a caching issue, as the times are always VERY near each other, and the second one is always after the first, but I'm not positive.

• Making a PHP object behave like an array?

  - by Mark Biek

  I'd like to be able to write a PHP class that behaves like an array and uses normal array syntax for getting & setting. For example (where Foo is a PHP class of my making): $foo = new Foo(); $foo['fooKey'] = 'foo value'; echo $foo['fooKey']; I know that PHP has the _get and _set magic methods but those don't let you use array notation to access items. Python handles it by overloading __getitem__ and __setitem__. Is there a way to do this in PHP? If it makes a difference, I'm running PHP 5.2.

• Makefile: expand dependencies

  - by Danyel

  First off, the title is very generic because there are just tons of ways of how to possibly solve this. However, I'm looking for a clean and neat way. Situation: I have two equal object files foo.o and foo-pi.o, the latter of which is position-independent (compiled with -fPIC). Both depend on foo.h and bar.h. Problem: How do I, without code duplication, declare dependency of all foo*.o to bar.h? Solutions so far: $(shell bash -c 'echo -ne foo{-pi,}.o'}: bar.h $(addsuffix .o, $(addprefix fo, o-pi o)): bar.h The first solution is not portable on systems that don't support bash, the second is a dirty solution since I could not figure out how to use empty strings in addprefix.

• Creating a PHP web page that enables you to reboot the server in Linux?

  - by Stuart

  I want to create a web page that allows the user to initiate a reboot on the linux server. Obviously this would only be avaliable for system admins and would also be controlled by using iptables. Below is a sample of code that I was thinking of using but I wanted to know if there is another way to do this and how also to use this in a web page? Also is there any thing else that I should consider? $command = "cat $pass | su -c 'shutdown -r now'"; $output = array(); try{ echo shell_exec($command); exec($command, $output); system($command, $output); } catch(Exception $e) { print "Unable to shutdown system...\n"; } foreach ($output as $line) { print "$line<br>"; } Thanks in advance.
