  • How do I make a PHP call whenever a form element is clicked?

    - by thinkswan
    I have a jQuery colorbox opened over top of my webpage (with a <select> drop down list) and I'd like to make an AJAX call every time a new <option> is selected from the drop down. I have the following code, but it's not picking up the select event. $('#cboxLoadedContent select[name=parent]').live('select', function() { $.get("edit.php", { fn: 'getFormatLevel', parent: $('select[name=parent]').val() }, function(data) { alert("Data Loaded: " + data); }); }); Any ideas why this isn't even recognizing my selector?

  • How do you convert a hexadecimal representation of data to binary data in PHP?

    - by Marcus Adams
    I'm familiar with php's function bin2hex() for converting binary data to its hexadecimal representation. However, what is the complement function to convert the hexadecimal representation of the data back to binary data? For example: $foo = "hello"; $foo = bin2hex($foo); echo $foo; // Displays 68656c6c6f How do I turn it back to hello? $foo = "68656c6c6f"; // Now what? There is no hex2bin() function.

  • Is there any legitimate use for bare strings in PHP?

    - by Robert
    This question got me thinking about bare strings. When PHP sees a string that's not enclosed in quotes, it first checks to see if it's a constant. If not, it just assumes it's a string and goes on anyway. So for example if I have echo $foo[bar]; If there's a constant called bar it uses that for the array key, but if not then it treats bar as a bare string, so it behaves just like echo $foo["bar"]; This can cause all kinds of problems if at some future date a constant is added with the same name. My question is, is there any situation in which it actually makes sense to use a bare string?

  • PHP application variable... maybe?

    - by James
    I went to a PHP job interview, I was asked to implement a piece of code to detect visitors are bots to crawl thru the website and steal content. So I implemented a few lines of code to detect if the site is being refreshed/visited too quickly/often by using a session variable to store last visit timestamp. I got told that session varaibles can be manupilated by cookies etc, so I am wondering if there is a application variable that I can use to store the timestamp information against visitor IPs eg $_SERVER[REMOTE_ADDR]? I know that I can write the data to a file but it's not very good for a high traffic website. Regards James

  • How to insert PHP script into HTML the best way?

    - by Mike
    Hello, I have to insert full path to every single image/css file of my website, because of url_rewriting and I'm looking for the most officiant way to do it. Of course I could do: <img src='<?php echo $full_path; ?>/images/theImg.jpg' alt='alternative text' /> But somewhere I saw people doing it like this, or something: <img src='{full_path}/images/theImg.jpg' /> Now do you know how the second example is possible, or is it just part of some framework and can't be used in normal document? Thanks for answers, Mike

  • php encrypting an integer to get only alphanumeric characters?

    - by Matthew Steiner
    When I use some of php's encryption functions, I end up getting a few characters I don't want (+, /, =). The problem is that my application doesn't allow these in the url. I'm wondering if there's a good way of encrypting an integer and having only alphanumeric characters in the result? I'm trying to pass some data through the url. I know it's possible to do some workarounds (put data in database and pass the id to the row or something), but I really want to try it this way. Ideas?

  • How to make php-closure compiler output to a predefined file name? (Updated)

    - by Mohammad
    Php-closure compiler (linked to source code) currently writes the compiled code to a md5 encoded filename. How can I make it so it write the compiled code to a predefined name like compiled_code.js? . . I think it has to do with the write() function on Line 164. It gets the filename via the _getCacheFileName() function (Line 272). function _getCacheFileName() { return $this->_cache_dir . $this->_getHash() . ".js"; } I've tried altering it to this: function _getCacheFileName() { //return $this->_cache_dir . $this->_getHash() . ".js"; return 'copiled_code.js'; } without any results. Thanks to all of you in advance!

  • Create unordered list tree menu from data stored in an table with the adjacency list model...php

    - by Ronedog
    I need to create a tree menu of "nth" subcategories. I settled on using the adjacency list model for my table structure, because I won't be updating this table very much and this seemed the easiest to implement for my use. I want to style the output using "ul" and "li" tags...I already have a css and jquery solution to do the styling. My problem comes from pulling the data out of the database and using a recursive function via PHP to build the list ... the list is a concatenated string that gets parsed to build the tree. I'm really having a hard time getting the closing "ul" and "li" tags to line up just where they need to be. Is this the best way to do this? Are there other better ways using arrays or something like that to do this? Any examples you can point me to of "best practices" for building a list like this will be appreciated. Thanks.

  • What is the fastest and best PHP IDE on Windows?

    - by vegatron
    I've tried a few PHP IDEs, but am still searching for the fastest one. All Java-based IDEs are too slow. I have 2 computers to work with: my home PC which is too fast, and my laptop which is good but can't handle heavy software. And I have to work on them both, so I'm looking for the best free IDE which is fast. I'm not talking about text editors, because I already have Notepad++ and it's great, but looking for extra features to help me save time. Any tips?

  • How do you use scripting language (PHP, Python, etc) to improve your productivity?

    - by Edwin
    Hi, I'm a Delphi developer on the Windows platform, recently read the PHP tutorial at W3CSchools, it looks interesting. We all know scripting languages are very good at web site development, but I also want to utilize it to improve my productivity or get some tedious tasks done quickly, maybe some quick-and-dirty string/file processing? How do you usually do with scripting languages apart from software development? And we need a responsive, decent IDE/editor in order to gain productivity when writing scripts for this purpose? Thanks for in advance!

  • What do I use when a cron job isn't enough? (php)

    - by mike
    I'm trying to figure out the most efficient way to running a pretty hefty PHP task thousands of times a day. It needs to make an IMAP connection to Gmail, loop over the emails, save this info to the database and save images locally. Running this task every so often using a cron isn't that big of a deal, but I need to run it every minute and I know eventually the crons will start running on top of each other and cause memory issues. What is the next step up when you need to efficiently run a task multiple times a minute? I've been reading about beanstalk & pheanstalk and I'm not entirely sure if that will do what I need. Thoughts???

  • Why Use PHP OOP over Basic Functions and When?

    - by Codex73
    There are some posts about this matter, but I didn't clearly get when to use Object Oriented coding and when to use programmatic functions in an include. Somebody also mentioned to me that OOP is very heavy to run, and makes more workload. Is this right? Lets say I have a big file with 50 functions, why will I want to call these in a class? and not by function_name(). Should I switch and create object which holds all of my functions? What will be the advantage or specific difference? What benefits does it bring to code OOP in php ? Modularity?

  • How can I download all files of a specific type from a website using PHP?

    - by CheeseConQueso
    I want to get all midi (*.mid) files from a site that's set up pretty simple in terms of directory tree structure. I wish we had wget installed here, but that's another party.... The site is VGMusic.com and the path containing all of the midi files is: http://www.vgmusic.com/music/console/nintendo/nes/ I tried glob'ing it out, but I suppose that glob only works locally? Here is what I wrote to try to make it happen (doesn't work.. obviously..): <?php echo 'not a blizzard<br>'; foreach(glob('http://www.vgmusic.com/music/console/nintendo/nes/*.mid') as $filename) { echo $filename.'<br>'; //$newfile = 'http://www.mydomain.com/nes/'.$filename; //copy($filename, $newfile) } ?> I tried it also without the http:// in there with no luck.

  • Opinions Required: Custom HTML Markup from PHP with or without tag prefix.

    - by buggedcom
    I've created a class in PHP that allows you to create custom HTML markup. It basically works a bit like FB Markup or EE tags. It works off a tag prefix, so you can add tags like this. <ctag:pagination per_page="20" total="500" page="0" base="http://localhost/page?page={page}" mode="smart" adjecents="5" /> My question is: Is the markup above better than the markup below? I'm asking as I'm considering branching my code to rework the tag matching so you can just generate custom html elements. It would well for a drop in HTML5 replacement service. Match the User Agent for a none HTML5 browser and replace the HTML5 elements with your own replacements. <pagination per_page="20" total="500" page="0" base="http://localhost/page?page={page}" mode="smart" adjecents="5" /> PS, if anybody wants to look at the class I've put a download here.

  • How to fetch message body and attachments in XML format using php/linux from Lotus Domino server?

    - by too
    Has anybody some information about accessing Lotus Domino server to fetch entire mail contents by http(s) requests from php linux server? The article by Andrei Kouvchinnikov describes well how to fetch message list in notes mail folders; after obtaining session id during login one can for example select top 100 messages by calling: https://your.server.domain/mail_db/mailbox.nsf/($Inbox)?ReadViewEntries&Start=1&Count=100 And this works perfectly. The problem arises when I am trying to get message contents (0A1DA5EEB7B65277C12576F50055D811 is an example message unique Id): https://your.server.domain/mail_db/mailbox.nsf/($Inbox)/0A1DA5EEB7B65277C12576F50055D811/?OpenDocument Such request in IE shows frameset with data hard to parse, in less common browsers like Opera it informs about unsupported browser. Ideally if it is possible to fetch notes message contents and all attachments by requesting it in the url, has anybody some information what request would it be? Link to Lotus web calls reference would be even more beneficial.

  • What exactly happens when I call a web service method using PHP::SOAP?

    - by Bedwyr Humphreys
    Say I have a simple client/server scenario with one method: // client code $client = new SoapCLient("service.wsdl"); $result = $client.getPi(); ... // server code function getPi(){ return 3.141; } $server = new SoapServer("service.wsdl"); $server.addFunction("getPi"); $server.handle(); Am I right in thinking that when the client makes a call to the getPi() method the addfunction() gets called everytime? Is this really how PHP SOAP web services work? Or is there some caching going on? Thanks.

  • How would I UPDATE these table entries with SQL and PHP?

    - by CT
    I am working on an Asset Database problem. I enter assets into a database. Every object is an asset and has variables within the asset table. An object is also a type of asset. In this example the type is server. Here is the Query to retrieve all necessary data: SELECT asset.id ,asset.company ,asset.location ,asset.purchaseDate ,asset.purchaseOrder ,asset.value ,asset.type ,asset.notes ,server.manufacturer ,server.model ,server.serialNumber ,server.esc ,server.warranty ,server.user ,server.prevUser ,server.cpu ,server.memory ,server.hardDrive FROM asset LEFT JOIN server ON server.id = asset.id WHERE asset.id = '$id' I then assign all results into single php variables. How would I write a query/script to update an asset?

Any help would be much appreciated..

  • Using PHP to place database rows into an array?

    - by Hamed Szilazi
    I was just wondering how i would be able to code perform an SQL query and then place each row into a new array, for example, lets say a table looked like the following: $people= mysql_query("SELECT * FROM friends") Output: | ID | Name | Age | --1----tom----32 --2----dan----22 --3----pat----52 --4----nik----32 --5----dre----65 How could i create a multidimensional array that works in the following way, the first rows second column data could be accessed using $people[0][1] and fifth rows third column could be accessed using $people[4][2]. How would i go about constructing this type of array? Sorry if this is a strange question, its just that i am new to PHP+SQL and would like to know how to directly access data. Performance and speed is not a issue as i am just writing small test scripts to get to grips with the language.

  • is there a multiple payment providers (paypal, ogone, ...) php module for use in a web app?

    - by Jorre
    We are building an ecommerce app where we want our users to pick out a (any provider we can make compatible with our app) payment provider. Up to today, we only support paypal and we have implemented this rather manually. We are looking for some sort of a module (free or commercial) to easily plugin in more payment providers to let customers accept payments through them. Our customers would use this to accept payments for sales in their web shops. Any ideas on such "modules"? I know of the Zend_Payment module but that's not updated anymore or isn't out yet at all. We run PHP in the Zend Framework if that matters.

  • [PHP] building html tables from query data... faster?

    - by Andrew Heath
    With my limited experience/knowledge I am using the following structure to generate HTML tables on the fly from MySQL queries: $c = 0; $t = count($results); $table = '<table>'; while ($c < $t) { $table .= "<tr><td>$results[0]</td><td>$results[1]</td> (etc etc) </tr>"; ++$c; } $table .= '</table>'; this works, obviously. But for tables with 300+ rows there is a noticeable delay in pageload while the script builds the table. Currently the maximum results list is only about 1,100 rows, and the wait isn't long, but there's clearly a wait. Are there other methods for outputting an HTML table that are faster than my WHILE loop? (PHP only please...)

  • How do I sum up weighted arrays in PHP?

    - by christian studer
    Hod do I multiply the values of a multi-dimensional array with weigths and sum up the results into a new array in PHP or in general? The boring way looks like this: $weights = array(0.25, 0.4, 0.2, 0.15); $values = array ( array(5,10,15), array(20,25,30), array(35,40,45), array(50,55,60) ); $result = array(); for($i = 0; $i < count($values[0]); ++$i) { $result[$i] = 0; foreach($weights as $index => $thisWeight) $result[$i] += $thisWeight * $values[$index][$i]; } Is there a more elegant solution?
