• Replacing tags inside the parent tag using DOM PHP

  - by user585303

  Here is what I got: <div id="list"> <ol> <li>Ordered list 1</li> <li>Ordered list 2</li> <ul><li>Unordered list inside ol ul</li></ul> <ol><li>Ordered list inside ol ol</li></ol> <ol> <ul> <li>Unordered list</li> <ol><li>Ordered list inside ul</li></ol> <ul> <ol> <li>Ordered list 1</li> <ol><li>Ordered list inside ol ol</li></ol> <ol> </div> I need somehow replace LI tags only inside div id="list" - OL tags I need so that it replaces only LI tags only within the first OL tags and not UL or the once inside OL - OL tags I tried using preg_replace_callback but it only replaces all LI tags inside id="list" and from what i figured it will be over my head to limit replacement only with first ol tags and not the rest, so I been suggested to try out PHP DOM since it should be as easy as div id="list" - OL I would appreciate if someone got me started with the code, maybe with something as replacing all LI tags with in the first OL tag within the whole content.

• Using Uploadify, I'm renaming uploaded files via uploadify.php, how do I get the check script to now check for this renamed file??

  - by Rob Macintosh

  I've modified my uploadify.php file to rename my uploaded files, i'm appending them with my clients company name. As you can see i'm using scriptData to set the company name, so that uploadify.php can use it. documents.php 'scriptData': { 'PHPSESSID': '<?php echo session_id();?>', 'client_company': '<?php echo $_SESSION['company'] . "-";?>' }, This all works great - but now it breaks my check.php. I'm using the default check script, but now it simply thinks the file doesn't exist, so it overwrites it. I've tried appending the client_company POST variable to the file check; check.php $fileArray = array(); foreach ($_POST as $key => $value) { if ($key != 'folder') { if (file_exists($_SERVER['DOCUMENT_ROOT'] . $_POST['folder'] . '/' . $_POST['client_company'] . $value)) { $fileArray[$key] = $value; } } } echo json_encode($fileArray); But it doesn't work :( Can anyone help?

• looking for advise on importing excel into mysql with php

  - by Ole Media

  Alright, see if I can pick your brains from you all. I'm currently working on a project where all the information comes from different clients, the only thing in common is that the received data is done with excel. The excel spread sheet that they present is just a bunch of references and codes, and the problem than I'm facing is that I need the references and codes to be entered in certain format in order for the website to work. The perfect situation will be to go to each client and teach how I would need the data, but I can't do that because of the large number of clients, and more importantly I will be interrupting their work flow. Each client has its own codes and reference model and they are not willing to change their process The good news is that there is a standard pattern for the codes, but I'm talking close to 200 thousand codes with a bunch of combination. They way that we are currently solving the problem is that we have a person who checks each excel sheet received, runs a few macros, and manually fixes those codes in which the macro was not able to fix. The person that is doing this, is already burn out and frustrated and I would like to automatize this process with php. Suggestions?

• Is there a way to access Joomla 1.5 user variables (like user id) from a Flex 4 application using a PHP Data Service?

  - by Zachary G. Schroeder

  I have written a script (in two files) that correctly displays a Joomla user id, like this: //this is testy.php define( '_JEXEC', 1 ); define('JPATH_BASE', dirname(FILE)); define( 'DS', DIRECTORY_SEPARATOR ); require_once ( JPATH_BASE .DS.'includes'.DS.'defines.php' ); require_once ( JPATH_BASE .DS.'includes'.DS.'framework.php' ); $mainframe =& JFactory::getApplication('site'); $id = JFactory::getUser()-id; The above file is located in the Joomla root folder. The other file is in a different directory and is as follows: //this is testid.php include '../../joomla/testy.php'; echo $id; However, and here is the rub, when I change the "echo" to a "return" and put the second code snippet inside my Flex 4 Data Service script file, like this... function getUserId() { include '../../joomla/testy.php'; return $id; } ...I get a Flex error that says this: Fatal error: Class 'JRequest' not found in /var/www/html/joomla/libraries/joomla/import.php on line 33 I am extremely confused by this error and would appreciate any suggestions that the stackoverflow community may have. Thanks so much! Zach

• how to achieve functionality of #def of c in PHP

  - by Sabya

  Well, I don't know if thats what I want. But here is my problem: In case of some error I am logging the FILE, CLASS, FUNCTION and LINE in a file. For that I am doing something like: myLog('['. __FILE__ . ']' . '[' . __CLASS__ . ']' . '[' . __FUNCTION__ . ']' . '[' . __LINE__ . ']'); The problem is everywhere I've to repeat that code in the parameter. and If I want to change the format, I've to change everywhere. How can I have something like: myLog(LOG_MSG_FORMAT); With PHP define it is not possible since it will give my the LINE number of the place where that definition is, not where the definition is getting used. Any solution to this is welcome. I am not bitchy about having C like functionality of #def.

• Why do people keep parsing HTML using regex? [closed]

  - by polygenelubricants

  As much as I love regular expressions, it's obvious to me that it's not the best tool for parsing HTML, especially given the numerous good HTML parsers out there. And yet there are numerous questions on stackoverflow that attempts to parse HTML using regex. And people would always point out what a bad idea that is in the comments. And the accepted answer would often have a disclaimer how this isn't really the ideal way of doing things. But based on the constant flow of questions, it still seems that people keep parsing HTML using regex, despite the perceived difficulty in reading and maintaining it (and that's putting correctness aside for now). So my question is: why? Is it because it's easy to learn? Is it because it's faster? Is it because it's the industry standard? Is it because there are already so many reusable regexes to build from? Is it because 100% correctness is never really the objective? (90% good enough?) etc... I'd also like to hear from the downvoters why they did so. Is it because: There's absolutely nothing wrong with using regex to parse HTML and asking "Why?" is just dumb? The premise of the question is flawed because the people who are using regex to parse HTML is such a small minority?

• working with a csv with odd encapsulation // php

  - by Patrick

  I have a CSV file that im working with, and all the fields are comma separated. But some of the fields themselves, contain commas. In the raw csv file, the fields that contain commas, are encapsulated with quotes, as seen here; "Doctor Such and Such, Medical Center","555 Scruff McGruff, Suite 103, Chicago IL 60652",(555) 555-5555,,,,something else the code im using is below <?PHP $file_handle = fopen("file.csv", "r"); $i=0; while (!feof($file_handle) ) { $line = fgetcsv($file_handle, 1024); $c=0; foreach($line AS $key=>$value){ if($i != 0){ if($c == 0){ echo "[ROW $i][COL $c] - $value"; //First field in row, show row # }else{ echo "[COL $c] - $value"; // Remaining fields in row } } $c++; } echo "<br>"; // Line Break to next line $i++; } fclose($file_handle); ?> The problem is im getting the fields with the comma's split into two fields, which messes up the number of columns im supposed to have. Is there any way i could search for comma's within quotes and convert them, or another way to deal with this?

• PHP mail function, some clients aren't showing my mails as html?

  - by Don

  I'm trying to send emails to my website members using the mail() function with PHP, The mails are in hebrew, and I want to send an html email, That's pretty much how I send it $mail_to = "[email protected]"; $message = " <html> some content here </html> "; $headers = "MIME-Version: 1.0" . "\r\n"; $headers .= "Content-type:text/html;charset=windows-1255" . "\r\n"; $headers .= 'From: "MyWebsiteName" <[email protected]>' . "\r\n"; $mail = mail($mail_to, $subject, $message, $headers ); It works completely fine with clients such as Gmail, or thunderbird users, but I viewed it in a few other clients, that aren't so famous, but still widely used in my country, and it just shows me the html source.. I'll also add that I've seen other mails in those clients that are working fine, so they are supporting html mails. What am I doing wrong?

• How to find every possible combination of an arbitrary number of arrays in PHP

  - by Travis

  I have an arbitrary number of nested arrays in php. For example: Array ( [0] => Array ( [0] => 36 [0] => 2 [0] => 9 ) [1] => Array ( [0] => 95 [1] => 21 [2] => 102 [3] => 38 ) [2] => Array ( [0] => 3 [1] => 5 ) ) I want to find the most efficient way to combine all possible combinations of each of these nested arrays. I'd like to end up with something that looks like this... Array ( [0] => "36,95,3" [1] => "36,95,5" [2] => "36,21,3" [3] => "36,21,5" etc... ) The order the results are combined in is not important. That is to say, there is no difference between "3,95,36", "36,95,3", and "95,36,3". I would like to omit these redundant combinations. Any suggestions on how to go about this would be much appreciated. Thanks in advance,

• how to decrease queries in php/mysql array selection loop

  - by Mac Taylor

  hey guys i need to show stories details and tags' names in my php/mysql project . for every story row, there is a filed named : tags that save tags id as an array Table name: stories table filed : tags example of tags filed : 1 5 6 space between them and i have a tag table that looks like this Table name : bt_tags Table fileds : tid,tag now problem : when using while loop to fetch all fields in story table , the page uses 1 query to show every stories' detail but for showing tag's names , i should query another table to find names , we have ids stored in story table now i used for loop between while loop to show tag names but im sure there is a better way to decrease page queries $result = $db->sql_query("SELECT * FROM ".STORY_TABLE." "); while ($row = $db->sql_fetchrow($result)) { //fetching other $vars ---- $tags_id = explode(" ",$row['tags']); $c = count($tags_id); for($i=1;$i<$c-1;$i++){ list($tag_name,$slug) = $db->sql_fetchrow($db->sql_query( 'SELECT `tag`,`slug` FROM `bt_tags` WHERE `tid` = "'.tags_id[$i].'" LIMIT 1' )); $sow_tags = '$tag_name,'; } im not allowed to change anything in database table how can i improve this script and show tag's names without using *for loop ?*

• PHP - file uploads and ways to prevent viruses from being uploaded in zip/rar archives

  - by Joe

  I am trying to provide a service on my website to allow users to upload files so others can download them. The issue is, since some of these files I will allow to upload will be .zip/.rar files, I am curious as to what ideas exist to help prevent the uploading of archives with Viruses/trojans etc. included. Some .zip files will include legitimate .exe files,though I am not sure what options I have. I thought about it and I don't have a method for verifying with a virus scanner on the server, since I am on shared hosting w/o the option to run a service like that... nor do I have the knowledge on how to do that. I am also aware there is no php class or database to scan the files for viruses. This means, my only options are to rely on: a). manual approval <-- not an acceptable option for me as it might become a busy site with thousands of uploads b). get the users to somehow point out it if has viruses through voting or "flagging", etc.... anyway, regarding "b" - what ideas would you suggest?

• PHP/mysqli: Inserting IP address with mysqli_stmt_bind_param()

  - by invarbrass

  Hello! I have a database table which contains an unsigned integer field to store the visitor's IP address: `user_ip` INT(10) UNSIGNED DEFAULT NULL, Here's the snippet of PHP code which tries to store the IP address: $ipaddr = $_SERVER['REMOTE_ADDR']; if ($stmt = mysqli_prepare($dbconn, 'INSERT INTO visitors(user_email, user_ip) VALUES (?,?)')) { $remote_ip = "INET_ATON('$ipaddr')"; mysqli_stmt_bind_param($stmt, 'ss', $email, $remote_ip); if (mysqli_stmt_execute($stmt) === FALSE) return FALSE; $rows_affected = mysqli_stmt_affected_rows($stmt); mysqli_stmt_close($stmt); } The INSERT operation succeeds, however the user_ip field contains a null value. I have also tried changing the parameter type in mysqli_stmt_bind_param() (which was set to string in the above example) to integer, i.e. mysqli_bind_param(... 'si',...) - but to no avail. I've also tried using the following bit of code instead of mysql's INET_ATON() SQL function: function IP_ATON($ipaddr) { $trio = intval(substr($ipaddr,0,3)); return ($trio>127) ? ((ip2long($ipaddr) & 0x7FFFFFFF) + 0x80000000) : ip2long($ipaddr); } It still doesn't work - the 'user_ip' field is still set to null. I've tried passing the $ip_addr variable as both integer & string in mysqli_bind_param() - to no avail. It seems the problem lies with the parameterized insert. The following "old-style" code works without any problem: mysqli_query(..., "INSERT INTO visitors(user_email, user_ip) VALUES ('$email',INET_ATON('$ipaddr'))"); What am I doing wrong here? Thanks in advance!

• PHP Array saved to Text file

  - by coffeemonitor

  I've saved a response from an outside server to a text file, so I don't need to keep running connection requests. Instead, perhaps I can use the text file for my manipulation purposes, until I'm read for re-connecting again. (also, my connection requests are limited to this outside server) Here is what I've saved to a text file: records.txt Array ( [0] => stdClass Object ( [id] => 552 [date_created] => 2012-02-23 10:30:56 [date_modified] => 2012-03-09 18:55:26 [date_deleted] => 2012-03-09 18:55:26 [first_name] => Test [middle_name] => [last_name] => Test [home_phone] => (123) 123-1234 [email] => [email protected] ) [1] => stdClass Object ( [id] => 553 [date_created] => 2012-02-23 10:30:56 [date_modified] => 2012-03-09 18:55:26 [date_deleted] => 2012-03-09 18:55:26 [first_name] => Test [middle_name] => [last_name] => Test [home_phone] => (325) 558-1234 [email] => [email protected] ) ) There's actually more in the Array, but I'm sure 2 are fine. Since this is a text file, and I want to pretend this is the actual outside server (sending me the same info), how do I make it a real array again? I know I need to open the file first: <?php $fp = fopen('records.txt', "r"); // open the file $theData = fread($fh, filesize('records.txt')); fclose($fh); echo $theData; ?> So far $theData is a string value. Is there a way to convert it back to the Array it originally came in as?

  I'm ajaxing over to this php file. $a = 'old'; $b = 'new'; if ($_POST['info-type'] == $a || $b) { $info = $_POST['info-type']; $query = "SELECT * FROM `tld` WHERE type = '".$var."'"; } $query = "SELECT * FROM `tld` "; $result = mysqli_query($link,$query); while($row = mysqli_fetch_assoc($result)) { echo '<div>'.$row['something'].'</div>'; } The data posted is either 'all' 'new' or 'old'. If i send the data as either new or old, the script works and outputs as expected. If the posted data is neither new or old but all instead, it fails and don't show any errors or respond anything back. (I've monitored via dev tools aswell) So, I tried this if ($_POST['info-type'] == $a || $b) { $info = $_POST['info-type']; $var = "SELECT * FROM `tld` WHERE type = '".$var."'"; } elseif ($_POST['info-type'] == 'all'){ $query = "SELECT * FROM `tld` "; } But the script still fails. If i fully remove the IF statements and use the query without the WHERE clause like it is after the elseif, it works?

• PHP generating csv not sending correct new line feeds

  - by sjw

  I have a script that generates a csv file using the following code: header('Content-type: text/csv'); header('Content-Disposition: attachment; filename="'.date("Ymdhis").'.csv"'); print $content; The $content variable simply contains lines with fields separated by commas and then finalised with ."\n"; to generate a new line. When I open the file in csv it looks fine however, when I try to use the file to import into an external program (MYOB) it does not recognise the End Of Line (\n) character and assumes one long line of text. When I view the contents of the file in notepad, the end of line character (\n) is a small rectangle box which looks like the character code 0x7F. If I open the file and re-save it in excel, it removes this character and replaces it with a proper end of line character and I can import the file. What character do I need to be generating in PHP so that notepad recognises it as a valid End Of Line character? (\n) obviously doesn't do the job.

• Break up PHP Pagination links

  - by Rabbott

  I have the following method that creates and returns markup for my pagination links in PHP. public function getPaginationLinks($options) { if($options['total_pages'] > 1) { $markup = '<div class="pagination">'; if($options['page'] > 1) { $markup .= '<a href="?page=' . ($options['page'] - 1) . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">< prev</a>'; } for($i = 1; $i <= $options['total_pages']; $i++) { if($options['page'] != $i) { $markup .= '<a href="?page='. $i . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">' . $i . '</a>'; } else { $markup .= '<span class="current">' . $i . '</span>'; } } if($options['page'] < $options['total_pages']) { $markup .= '<a href="?page=' . ($options['page'] + 1) . ((isset($options['order_by'])) ? "&sort=" . $options['order_by'] : "") . '">next ></a>'; } $markup .= '</div>'; return $markup; } else { return false; } } I just recently discovered (to my surprise) that i had reached 70+ pages which means that there are now 70+ links showing up at the bottom.. I'm wondering if someone can help me break this up.. I'm not sure how most pagination works as far as showing the numbers if im on say.. page 30, ideas?

• Serving .docx files through Php

  - by user275074

  Hi, I'm having issues when attempting to serve a .docx file using Php. When uploading the file I detect the file mime type and upload the file using the file with the correct extension based on the mime type; e.g. below: application/msword - doc application/vnd.openxmlformats-officedocument.wordprocessingml.document - docx When attempting to serve the files for download, I do the reverse in detecting the extension and serving based on the mime type e.g. public static function fileMimeType($extention) { if(!is_null($extention)) { switch($extention) { case 'txt': return 'text/plain'; break; case 'odt': return 'application/vnd.oasis.opendocument.text'; break; case 'doc': return 'application/msword'; break; case 'docx': return 'application/vnd.openxmlformats-officedocument.wordprocessingml.document'; break; case ('jpg' || 'jpeg'): return 'image/jpeg'; break; case 'png': return 'image/png'; break; case 'pdf': return 'application/pdf'; break; default: break; } } } All files appear to download correctly and open fine but when attempting to open a docx file, Word (on multiple files) throws a error stating the file is corrupt. Any ideas would be great, thanks.

• Modify php shopping cart to support multiple drop down menus

  - by Thomas

  I have a shopping cart script that I am trying to modify to support multiple product selection. As it is now, the customer can select a product from a single drop down menu. Now, I would like to add multiple dropdown menus (all populated with the same options). Here is the php that outputs the dropdown menu: if($eshopoptions['options_num']>1){ $opt=$eshopoptions['options_num']; $replace.="\n".'<label for="eopt'.$theid.'"><select id="eopt'.$theid.'" name="option">'; for($i=1;$i<=$opt;$i++){ $option=$eshop_product['products'][$i]['option']; $price=$eshop_product['products'][$i]['price']; if($option!=''){ if($price!='0.00') $replace.='<option value="'.$i.'">'.stripslashes(esc_attr($option)).' @ '.sprintf( _c('%1$s%2$s|1-currency symbol 2-amount','eshop'), $currsymbol, number_format($price,2)).'</option>'."\n"; else $replace.='<option value="'.$i.'">'.stripslashes(esc_attr($option)).'</option>'."\n"; } } Is there some really simple way of getting the code to output the menu say 3 times instead of once?

• PHP SDK for Facebook: Uploading an Image for an Event created using the Graph API

  - by wenbert

  Can anyone shed some light on my problem? <?php $config = array(); $config['appId'] = "foo"; $config['secret'] = "bar"; $config['cookie'] = true; $config['fileUpload'] = true; $facebook = new Facebook($config); $eventParams = array( "privacy_type" => $this->request->data['Event']['privacy'], "name" => $this->request->data['Event']['event'], "description" => $this->request->data['Event']['details'], "start_time" => $this->request->data['Event']['when'], "country" => "NZ" ); //around 300x300 pixels //I have set the permissions to Everyone $imgpath = "C:\\Yes\\Windows\\Path\\Photo_for_the_event_app.jpg"; $eventParams["@file.jpg"] = "@".$imgpath; $fbEvent = $facebook->api("me/events", "POST", $eventParams); var_dump($fbEvent); //I get the event id I also have this in my "scope" when the user is asked to Allow the app to post on his behalf: user_about_me,email,publish_stream,create_event,photo_upload This works. It creates the event with all the details I have specified. EXCEPT for the event image. I have been to most of Stackoverflow posts related to my problem but all of them are not working for me. (EG: http://stackoverflow.com/a/4245260/66767) I also do not get any error. Any ideas? THanks!

• PHP hashing function not working properly

  - by Jordan Foreman

  So I read a quick PHP login system securing article, and was trying to sort of duplicate their hashing method, and during testing, am not getting the proper output. Here is my code: function decryptPassword($pw, $salt){ $hash = hash('sha256', $salt . hash('sha256', $pw)); return $hash; } function encryptPassword($pw){ $hash = hash('sha256', $pw); $salt = substr(md5(uniqid(rand(), true)), 0, 3); $hash = hash('sha265', $salt . $hash); return array( 'salt' => $salt, 'hash' => $hash ); } And here is my testing code: $pw = $_GET['pw']; $enc = encryptPassword($pw); $hash = $enc['hash']; $salt = $enc['salt']; echo 'Pass: ' . $pw . '<br />'; echo 'Hash: ' . $hash . '<br />'; echo 'Salt: ' . $salt . '<br />'; echo 'Decrypt: ' . decryptPassword($hash, $salt); Now, the output of this should be pretty obvious, but unfortunately, the $hash variable always comes out empty! I'm trying to figure out what the problem could be, and my only guess would be the second $hash assignment line in the encryptPassword(..) function. After a little testing, I've determined that the first assignment works smoothly, but the second does not. Any suggestions? Thanks SO!

• Parsing XML elements with dynamic namespace prefix in PHP

  - by BugKiller

  I have the following XML ( you can say SOAP request ) : <SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope> I use the following code and it works fine : <?php $myRequest ='<SOAPENV:Envelope xmlns:SOAPENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:NS="http://xyz.gov/headerschema" > <SOAPENV:Header> <NS:myHeader> <NS:SourceID>223423</NS:SourceID> </NS:myHeader> </SOAPENV:Header> </SOAPENV:Envelope>'; $xml = simplexml_load_string($myRequest, NULL, NULL, "http://schemas.xmlsoap.org/soap/envelope/"); $namespaces = $xml->getNameSpaces(true); $soapHeader = $xml->children($namespaces['SOAPENV'])->Header; $myHeader = $soapHeader->children($namespaces['NS'])->myHeader; echo (string)$myHeader->SourceID; ?> The Problem I know the prefix ( SOAPENV + NS ) , but the clients could change the prefix to whatever they want, so they may send me xml document that has ( MY-SOAPENV + MY-NS) prefixes. My Question How can I handle this since the namespace prefixes are not static , how can I parse it ? Thanks
