PHP - Newb Preg_match Problem
Hi, preg_match isn't working the way I feel it should.
The idea, when i finally get this script working, is to echo an order form back to the client (so they can see what they've ordered). At the moment I'm just trying to get the product description for each ordered product. $aryOrder: prodCode[6722] with a value of (for instance) 2 prodCode[6724] with a value of (for instance) 1 etc (only ordered products present in the array) prodDB.txt 6722 Hydrocolloid Blister Care 6724 Toe Spreader etc All products present in text file (prode code Description) BUT I get an echo with no matches for any ordered product (or any prod for that matter) i.e. no match: 6724, 6724 TOE SPREADER when clearly, the product code (6724 $aryItem) is present in the text file line ($line_of_text). I just don't get it! foreach($aryOrder as $aryItem => $qty) { $file_handle = fopen("prodDB.txt", "r"); while (!feof($file_handle)) { $line_of_text = fgets($file_handle); if (preg_match($aryItem, $line_of_text)) { echo "Matched! $aryItem, $line_of_text QTY: $qty <br>"; } else { echo "no match: $aryItem, $line_of_text <br>"; } } fclose($file_handle); } I'm completely new to PHP, trying to work it out from the manual, so I've probably made a very basic mistake, and may even be going about this in entirely the wrong way. Any help much appreciated, Steve Similar TutorialsHey guys,
I am stuck on this preg_match if statement. I want to allow ' and " in the variable string but for some reason it keeps reporting invalid characters when I add ' or " to the string.
Any help would be appreciated as I have tried tons of combinations after searching google.
Thanks!
if(preg_match("/[^a-zA-Z0-9\-\_\,\!\?\.\'\"\ \/]+/i",$_POST['article_title'])) { $err[]='<p class="error" style="color: #ed1c24;">Your Title contains invalid characters!</p>'; } When I use the following code to check for posted characters it allows the insertion of ( ) brackets to be posted. if(!preg_match('/^([-_ a-z0-9]){2,50}$/i', $_POST['title'])) { echo "<script>alert('Please enter a Title 2-50 alphanumeric characters,\\nspaces, hyphens and underscores also accepted!)</script>"; } It should on allow 2-50 alphanumeric characters and spaces, hyphens and underscores! What am I missing? This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=329322.0 I had some code that I'm pretty sure used to work, basically something like the below. Code: [Select] if (preg_match("/[a-zA-Z0-9]+/", $_POST['title'])) { echo $_POST['title'];exit(); } Now i just don't get why it always returns true, even when entering special characters like "!#%?".. The only thing which comes to mind, is that i recently made a move to UTF-8..

How do I properly write this statement? Thanks Ben Hi All, Im modifying someone elses PHP code (survey tool) (and i havent done PHP for years) Basically the code exports to an external csv file to a file called export.csv However everytime i get it to export, it creates copies. ie it will export to export(2).csv and export(3).csv. How can i make it so that it exports and overwritesa/ammed the existing export.csv file? I had a look at the code and i believe this code below is doing the exporting but not sure code doing the export ( i think) Code: [Select] <?php include('classes/main.class.php'); include('classes/special_results.class.php'); $survey = new UCCASS_Special_Results; echo $survey->results_csv(@$_REQUEST['sid'],$_REQUEST['export_type']); ?> The class that it uses to export Code: [Select] <?php //====================================================== // Copyright (C) 2004 John W.

For example $_SESSION['customerid'] all the incoming customers. I also use SESSION variables with a different value for the managers to look at and keep track of customer data. eg : $_SESSION['customer']['firstname'] I am expecting many customers and managers to be simultaneously using the site. QUESTION: Do I need to increment the SESSION variable in some way in order to avoid that a session gets overwritten, or will my SESSION variables keep track and keep everything separated by dint of the fact that they contain different values ? so far my testing shows that things are working correctly, but I can only test with 3 / 4 virtual users in different browser windows . Hi - wondering if someone can give a little guidance: Why doesn't this trim the whitespace out of the string postzip? trim(strtoupper(((isset($_POST["postzip"]))?$_POST["postzip"]:""))) Thanks A couple months back, I asked on a gaming forum if anyone knew of a website that would track your *Steam Wishlist and email you when one of your wishlist games went on sale. No one at the time knew of a **solution, so I decided to buy "PHP, MySQL and Javascript" and try to roll my own. I managed to get the basics working. After the basics, I started thinking about fun stuff I could do with the data I collected from Steam regarding the games that go on sale regularly. The first part of my code file_get_content's the ***sale page(s) of games, and sucks out the games name, regular price, sale price, and the games homepage URL on Steam. This is enough to accomplish my basic task. The second part is where I need help, and that's getting more details on the game. The additional details I want to get about the game include its Publisher and Developer, and to get that detail I need to go to the games homepage URL I previously got from the global sale page. The issue is this: Some games have an age-restriction limitation, and you have to fill out a date form before entering the games homepage. An example of one of those pages would be: http://store.steampowered.com/agecheck/app/1250/ I want to be able to POST a legal age to the above URL, and then (this is where I'm hazy) "re-load" the same URL, authorized by my previous POST. Is that possible? * Steam is a digital download service for computer games. ** Subsequently, there was another website found. But I was well into developing my solution and having fun. *** Example: http://store.steampowered.com/search/?specials=1 I'm working on an email template system where my client will go to a page and copy & paste the source code into their crm system. I'm trying to find a way to automatically replace the image path without the use of echo if possible. I've figured this out already with this script: Code: [Select] <? function GetFileDir($php_self){ $filename = explode("/", $php_self); // THIS WILL BREAK DOWN THE PATH INTO AN ARRAY for( $i = 0; $i < (count($filename) - 1); ++$i ) { $filename2 .= $filename[$i].'/'; } return $filename2; } ?> But I don't wanna have to go in and put Code: [Select] <?php echo GetFileDir("http://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']); ?> before all the image paths. So basically anywhere that src="images/whatever.jpg" is listed it will replace "images/" with "http://www.mydomain.com/images/whatever.jpg" is it possible to do this without having to place code before "images" ? So I have a count down timer on my site. http://fpsboost.net And I am clueless as to how I would set a final date with this. Cant find where it's grabbing the info for "finaldate" or anything like that. Want to set the final date to feb 1st 2015 Javascript newb here. Anyone willing to help would be greatly appreciated. Thanks in advance! Btw, I'm using a generic js countdown timer from: http://hilios.github...uery.countdown/ called "The Final Countdown for jQuery v2.0.4" It was preloaded in a template that I downloaded for my site.

The following query or while loop is only increasing the ArticleID variable every 3rd time the script is run, I've narrowed it down to the following code snippet. Can you spot a problem with this, I'm in my first week of PHP and MySQL and I can't see any problem with it.

Now for the life of me, I can't do anything with it. I've tried json_decode() with the true argument there and not. Code: [Select] $output = json_decode($geocode, true); $output = json_decode($geocode); vardump($output) is NULL. So, I thought, well maybe I don't need to decode it, but I can't figure out how to parse it. I'm lost. This admittedly is my first attempt as trying to work with a jason object, but jeesh, it doesn't seem like it should be that hard. Can someone start me in the right direction? I have a simple form that connects to this php page. Only two variables, "ArticleDescription" & "URL". I've tried a number of things, several of which are listed below, but have had no success.
