• variables in batch scripts

  - by richzilla

  I'm trying to set up a batch file to automatically deploy a php app to a web server. Basically, what I want is an entirely automated process: I would just give it a revision number from the repository and it would then export the files, upload via ftp and then update deployment info at the repo host (codebase). However, I'm starting from scratch here. How would I set up a batch file to accept a variable when it was run? For example, the command myfile.bat /revision 42 should deploy revision 42 to my server. If anyone can point me in the right direction I'd appreciate it.

• Stackoverflow interesting tags

  - by Tom

  So, that's how works Interesting Tags: I add into them my interested tags like php, mysql, jquery and so on. Then, if any of questions has the same tags as mine it makes background orange. I understand how to use jquery to do that (there were related questions to that), but without mysql it can't be done. Now, here is a question. How is it done? I imagine like that: There is a row in mysql for every member, let's call it "interested_tags". After I write and submit my tag through input, it is being written in a row "interested_tags". Then, the main page has a query which shows all answers and it always checks answer's with mine tags with strpos like this if(strpos($question_tags, $my_tags) === true) {        //and here will be made background orange } Am I thinking right or is there any way to do it?

• Need advice on cron job'ing a very large process

  - by Arms

  I have a PHP script that grabs data from an external service and saves data to my database. I need this script to run once every minute for every user in the system (of which I expect to be thousands). My question is, what's the most efficient way to run this per user, per minute? At first I thought I would have a function that grabs all the user Ids from my database, iterate over the ids and perform the task for each one, but I think that as the number of users grow, this will take longer, and no longer fall within 1 minute intervals. Perhaps I should queue the user Ids, and perform the task individually for each one? In which case, I'm actually unsure of how to proceed. Thanks in advance for any advice.

• Function to set an auth_token

  - by john mossel

  In my form I have a hidden field: <input type="hidden" name="auth_token" value="<?php echo $auth_token; ?>"> This value is also stored in a session and a variable: $_SESSION['auth_token'] = hash('sha256', rand() . time() . $_SERVER['HTTP_USER_AGENT']); # TODO: put this in a function $auth_token = $_SESSION['auth_token']; When the form is submitted the two values are compared. It's a basic form token. Should this be made into two functions or just one when refactored? set_form_token() and get_form_token(), get_form_token() returning the session value, then I can compare it in my main code. What is the proper way of doing this?

• What is the most efficient way to store and access images

  - by MT

  I am working on a project which has to store tens and thousands of images on a server and let the users access them. I need the most efficient method to store these images and to retrieve them. Also, I need information about which technology I should opt. I haven't started the project yet. So, I am thinking between PHP w/ CodeIgniter and Ruby on Rails. PS: The site is something similar to Flickr except that the images are uploaded only by the Authors of the content, and not by the users.

• submit button on html to output result on same page

  - by amateur

  Hi, Although this seems like something very basic, but no matter what I tried I couldn't get my head around it. Basically I want a html form where a user types in their ID number in an input text box and when they hit the submit button it displays their email address which is their company ID number @ company.com, such as below <form action=""> ID Number: <input type="text" name="idnumber" /><br/> <input type="submit" value="Whats my email address" /> </form> <p>Your email address is 'idnumber'@email.com</p> Can this even be done using html or would I need to use Javascript or PHP for it? Thanks

• passing array fields to jquery ajax

  - by Rob Brandt

  I have a form I am submitting via jquery ajax. Early in the form, I have this field: <select name="inquirymodule[]" id="inquirymodule"> The user can add as many as they like, and all the selects go into the inquirymodule[] array. The jQuery looks like this: jQuery.ajax({ type: 'POST', url: 'ajax.php', dataType: 'json', data: { inquirymodule: jQuery("select[name='inquirymodule[]']").serialize(), }, error: function(XMLHttpRequest, textStatus, errorThrown) { alert('error'); } }); That works fine. Trying to do the same thing with a date, like this: <input class="formInput" type="text" id="startBreak0" name='startbreak[]' /> adding startbreak: jQuery("select[name='startbreak[]']").serialize() to the ajax call. It doesn't work, I cannot see why. Suggestions?

• Change find() type of contained model or array transformation

  - by Ramon Marco Navarro

  I have the following model associations: Response->Survey Response->Question Response->Choice Survey->Question Question->Choice I want to create a form where I could answer all the questions for one survey. So I used the following to return the needed data: $questions = $this->Response->Question->find('all', array( 'conditions' => array('survey_id' => $id), 'contain' => array('Choice') ) ); Sample output for debug($questions). Questions Is there a contain() option so that an associated model returns in the find('list') format so that I could use: foreach($question as $questions) { $this-Form-select('field_name', $question['Choice']); } If no option is available, how could I do this using PHP's builting array methods? PS: The foreach block won't turn into a code block. If someone could edit and fix it, please do so and delete this line. Thank you.

• Is there a way to check if a host is up?

  - by Rob

  I'm trying to do this in PHP. I need to check if a specified host is "up" I thought of pinging the specified host (though I'm not sure how I would, since that would require root. --help here?) I also though of using fsockopen() to try to connect on a specified port, but that would fail too, if the host wasn't listening for connections on that port. Additionally, some hosts block ping requests, so how might I get around this? This part isn't a necessity, though, so don't worry about this too much. I realize this one might get tricky.

• Unset array element inside a foreach loop

  - by Richard Knop

  So here is my code: <?php $arr = array(array(2 => 5), array(3 => 4), array(7 => 10)); foreach ($arr as $v) { $k = key($v); if ($k > 5) { // unset this element from $arr array } } print_r($arr); // now I would like to get the array without array(7 => 10) member As you can see, I start with an array of sinwgle key = value arrays, I loop thorugh this array and get a key of the current element (which is a single item array). I need to unset elements of the array with key higher than 5, how could I do that? I might also need to remove elements with value less than 50 or any other condition. Basically I need to be able to get a key of the current array item which is itself an array with a single item.

• TinyMCE: experiences, options

  - by YsoL8

  Hi I am considering using TinyMCE to handle the textboxes on sites I develop. I have the production version downloaded. At first I will be using it for the backend of a client's site on a deadline and I need it to work out of the box initally. In the future I also like the customisation options. Basically, does TinyMCE work, is it stable and is it cross browser compatible in a normal server environment? I am a PHP developer with limited Javascript skills.

• Offer access to a private page without login

  - by dccarmo

  So I've been struggling with a nice and easy way to allow users to access a private page without asking them to fill out a login/password form. What I'm thinking about using right now is for each private page I generate a uniqueid (using php uniqid function) and then send the URI to the user. He would access his private page as "www.mywebsite.com/private_page/13ffa2c4a". I think it's relatively safe and user friendly, without asking too much of information. I thought maybe when the user access this page it would ask for it's e-mail just to be sure, but the best would be nothing at all. Is this really safe? I mean not internet banking safe, but enough for a simple access? Do you think there's a better solution? Thanks. :)

• Create numbers within an array that add up to a set amount

  - by RussellDias

  I'm fairly new to PHP - programming in general. So basically what I need to accomplish is, create an array of x amount of numbers (created randomly) who's value add up to n: Lets say, I have to create 4 numbers that add up to 30. I just need the first random dataset. The 4 and 30 here are variables which will be set by the user. Essentially something like x = amount of numbers; n = sum of all x's combined; create x random numbers which all add up to n; $row = array(5, 7, 10, 8) // these add up to 30 Also, no duplicates are allowed. I need the values with an array. I have been messing around with it sometime, however, my knowledge is fairly limited. Any help will be greatly appreciated. Cheers

• MySQL Insert Query Randomly Takes a Long Time

  - by ShimmerTroll

  I am using MySQL to manage session data for my PHP application. When testing the app, it is usually very quick and responsive. However, seemingly randomly the response will stall before finally completing after a few seconds. I have narrowed the problem down to the session write query which looks something like this: INSERT INTO Session VALUES('lvg0p9peb1vd55tue9nvh460a7', '1275704013', '') ON DUPLICATE KEY UPDATE sessAccess='1275704013',sessData=''; The slow query log has this information: Query_time: 0.524446 Lock_time: 0.000046 Rows_sent: 0 Rows_examined: 0 This happens about 1 out of every 10 times. The query usually only takes ~0.0044 sec. The table is InnoDB with about 60 rows. sessId is the primary key with a BTREE index. Since this is accessed on every page view, it is clearly not an acceptable execution time. Why is this happening? Update: Table schema is: sessId:varchar(32), sessAccess:int(10), sessData:text

• Check if exists, if so, update by 1++, if not insert

  - by Scarface

  Hey guys quick question, I currently have an insert statement $query= "INSERT into new_mail VALUES ('$to1', '0')"; where fields are username, and message_number Currently what I would do to check if the entry exists, is do a select query then check the number of rows with mysql_num_rows (php). If rows==1 then I get the current message_number and set it equal to $row['message_number']++1. Then I update that entry with another query. Is there an easier way to do all this in just mysql with just one query (check if exists, if not insert, if so update message_number, increase by 1)?

• Scheduled cron job to check for pending activity

  - by luckytaxi

  Using PHP ... This is for my personal use so I'm thinking maybe 3-4 emails a day. I'm at a point where I can send an email to a dedicated email address where my script parses the message and stores it into a DB. Now, I need to figure out the best way to check the records in the DB for any upcoming task. I feel like I'm missing something, maybe like a trigger field as to when a reminder should go out. However, that's not a concern to me at the moment since I'll just send an alert 15 mins prior to the due date. Question is, shoudl I run a cron job that queries the DB every minute? I take it the query will have to say something like "select all tasks that is due within 15 minutes."

• open window with dynamic content

  - by julio

  Is it possible to open a window from PHP that has predefined content? It's obvious how you can open a window from a javascript link that frames an existing page, or just do a target=_blank from a regular a tag that references an existing page. But I am generating a bit of content, and want that content to be opened in a new link (or streamed to the viewer)-- something like (clearly psuedo code!): $content = "Hello World. <br />Nice to meet you!"; <a href="#" target="_blank" content=$content>Open up!</a> Is this possible? Thanks!

• How do I create a no-javascript url hash handler for my website?

  - by Kenny Bones

  Ok, I'm not sure how this is normally done. But I've got a script that basically empties a div of content and then loads content from a div from a separate webpage, without reloading the current page. This works great. It's taken from this example actually, from net tuts (great site btw) http://nettuts.s3.amazonaws.com/011_jQuerySite/sample/index.html And the guy who wrote this even though about handling the url's since the url don't change when using his method. So he wrote a javascript snippet that looks up the url and loads the content accoringly. Which is not working btw. But I was thinking about people who don't have javascript enabled, or iPhone and iPad users ;) Copying URLs and sending to a friend won't work at all. So how is this typically done? And can it be done without javascript? Possibly by php?

• User class - 'load' data

  - by John

  <?php class User { private $id; private $username; public function __construct($id = null) { $this->id = $id; if (!is_null($this->id)) { $this->load(); } } public function load() { } } ?> In the 'load' method I am going to load all the information from the current user (id) But I wonder how is the best way to load all info. I could grab all data and then just assign all private variables, but I assume there must be another "cheaper" way to get all the data so I can use as such $this-variable; And not have to ASSIGN every single data row, I select in the load method. How?
