PHP - Preg_match - Characters Slipping Through
This should be simple, but it doesn't seem to work. This preg_match should not be allowing other characters like # % and others, but it does. In other words, it does not hit the error message section if a pound sign or percent sign is entered in the 'answer' field on the form. I'm trying to only allow the characters that are listed: letters, numbers, single quote, exclamation, period, comma, space, dash and question mark. Can anyone see why this wouldn't be working? Thanks!
Code: [Select] $answerClean = trim($_POST['answer']); if( !preg_match("/^[A-Za-z0-9'!., -?]{2,150}$/", $answerClean) ) { $message = $message."You have not provided a valid answer for the question."; } Similar TutorialsThis topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=313299.0 Hi,
I don't know much about php. Recently my host updated php version to 5.4 and i function eregi() is deprecated errors, so after some googling, replaced it with preg_match but i am stuck with errors
Code:
preg_match("^ and", "", $mid_str)
Error: Warning: preg_match(): No ending delimiter '^' found
Tried the following method but not working
preg_match("/^ and/", "", $mid_str)
Can you guys help me with correct code?
Thanks for looking.
in my site search some of the results come out still with html. i have used the strip tags function but how would i use the preg_match function to get rid of the "> still left over? Hi,
I have a "scraped" string and want to use the preg_match() to give me just a pice of it.
The string is from a webpage, but is dynamic....
here´s the typical string format:
<a class="stripped-link lightblue-link profile-page-link" href="/x/xxx+xxx+xxx/xxxx">HER IS THE WANTED TEXT</a>
The orange is static. The green (the xxxx is the dynamic part of the string)
Can I use the preg_match() for this?
thanks (and yes I´m a newbe.... )
I'm pretty new to this, How exactly could i get the text between the www. and .com? so if i have a url: http://www.facebook.com I want to just return "facebook" Hi, I have the following code which FTPs to a site, gets the source code for a HTML file and then puts the data inbetween <TITLE> and </TITLE> into an array and this works fine: <?php $file = file_get_contents("ftp://user:pass@domain/public_html/index.html", "r"); if (!$file) { echo "<p>Unable to open remote file.\n"; exit; } preg_match_all ('/<TITLE>(.*)<\/TITLE>/msU', $file, $matches, PREG_SET_ORDER); print_r ($matches); ?> Rather than finding a match for data between <TITLE> and </TITLE> however I would like it to pull back what is inbetween the following: <!--START--> and <!--END--> I have tried the following but it doesn't put anything into the array: preg_match_all ('/<!--START-->(.*)<\/!--END-->/msU', $file, $matches, PREG_SET_ORDER); This is the content of the html file if this helps: Code: [Select] <TITLE>The Title</TITLE> <!--START--><p><strong>Some Text</strong></p> <p><strong><img src="images/IMAG0152_2.jpg" alt="" width="200" height="100" /></strong></p> <!--END--> i can get a match on stuff between TITLEs but not START and END.. I'm not sure how to change preg_match_all to work!! i've tried loads of combinations but can't get any to work, but i'm not really sure on modifiers and patterns or escaping etc, if anyone could help that would be great. Thanks in advance kev. I have a DOMDocument which I inspect an HTML page for links (href) That part works however I am not sure how to use preg_match if I only want to display a link in this layout: <tr> <td headers="c1"><a title="Link to entity information." tabindex="1" href="CORPSEARCH.ENTITY_INFORMATION?p_nameid=3236937&p_corpid=3227476&p_entity_name=%41%72%77%65%6E%20%45%71%75%69%74%69%65%73&p_name_type=%41&p_search_type=%42%45%47%49%4E%53&p_srch_results_page=0">ABC LLC</a></td> </tr> I hope someone is really good at preg_match to help me. Thanks. Im trying to match this string, but i dont wat to match normal words like "hello world 646" Code: [Select] $string = "2ab055843241f20044af82ae0d5ace04"; //always over 15 chars - without spaces if ( preg_match('~^[0-9\s]+$~D', $string)) { echo 'yes'; } If i can do it with preg_match that would be great information.txt <li><img src="http://www.lol.com" alt="0" /></li> <li><img src="http://www.lol.com" alt="1" /></li> <li><img src="http://www.lol.com" alt="4" /></li> <li><img src="http://www.lol.com" alt="9" /></li> <li><img src="http://www.lol.com" alt="1" /></li> <li><img src="http://www.lol.com" alt="7" /></li> <li><img src="http://www.lol.com" alt="2" /></li> How can I get the alt="$ValueIwant" for each with a preg_match I need to select an array item based on my preg result. for example: Code: [Select] $content = 'test-1'; $match = preg_replace('|test-([0-9])|', $array['\\1'], $content); is this possible? I know $regex_pattern is wrong but I need a solution to find a content between <body> and </body>. Code: [Select] <?php $content = "<html><head><title>Your IP</title></head><body>Your IP Address: 63.1.142.154</body></html>"; $regex_pattern = "/<body>(.*)<\/body>/"; $preg_match($regex_pattern,htmlspecialchars($content),$matches); print_r( $matches ); ?> i'm trying to grab the file name from mediafire to my database caption, I have rapidshare working fine. here's the code for rapidshare Code: [Select] if($type==1) { $words=$links[$j]; preg_match("/rapidshare\.com\/files\/\d+\/(.+)/",$words,$match); unset($words); $words=$match[1]; unset($match); $words=preg_split("/[_\.\-]/",$words); $lastword=array_pop($words); if($lastword=="html") array_pop($words); $words=implode(" ",$words); $words=preg_replace("/\s{2,}/"," ",$words); $caption=mysql_real_escape_string($words); unset($words); }How ever, i'm not sure which preg_match would be the correct one for mediafire.. appreciate any help. Why dosent this work, im trying to match upper case, lower case and numbers only Code: [Select] $id = '3xDJ7@#'; if (!preg_match('/^[a-zA-Z0-9]/', $id)){ echo "ERROR!"; }else{ echo 'ok'; } This always echos "ok" im trying to make a script so i can get users details like longitude, latitude etc

How do i add a second word? Hi guys, I have been using this code: preg_match('/<h2>(.*?)<\/h2>/', $data, $matches); which i changed to: $tag1 = 'h2'; $tag2 = 'h2'; preg_match('/$tag1(.*?)$tag2/', $data, $matches); however i need it to work allowing variables (of any character or symbol) within $tag1. I tried $tag1 = 'h(.*?)2'; $tag2 = 'h2'; preg_match('/$tag1(.*?)$tag2/', $data, $matches); but that does not work .... essentiall the whole thing would work like this (example only): firstpartoftag1VARIABLE1lastpartoftag1VARIABLE2tag2 ps the preg_match should only capture the VARIABLE2 data not VARIABLE1 any ideas or help would be much appreciated cheers in advance Hey guys, In my contact form i have the action: preg_match but i've come accross a problem.
