PHP - Stripping Tags
It seems like there should be a dedicated php function to strip a SPECIFIC tag, rather than the functionality of strip_tags.
I'm using this: Quote function stripSingleTags($tags, $string) { foreach( $tags as $tag ) { $string = preg_replace('#</?'.$tag.'[^>]*>#is', '', $string); } return $string; } But this will not help me if for example I want to trip out scripts <script> ... </script>. Is there a better way? Similar TutorialsHi, this is probably really simple for the majority here, but it's catching me out. I want to know what I need to add to the code below to strip <> HTML tags from the field post_title. Hope somebody can help. Thanks in advance. Code: [Select] <?php mysql_connect("********", "********", "********") or die(mysql_error()); mysql_select_db("website_news") or die(mysql_error()); $data = mysql_query("SELECT * FROM news_posts ORDER BY post_date DESC LIMIT 0, 5") or die(mysql_error()); while($info = mysql_fetch_array( $data )) { Print "<font color='black' face='arial'><li><a href='/website/news/?p=".$info['ID'] . "'>"; if ( strlen($info['post_title']) > 60) { $PostTitle = substr($info['post_title'], 0, 60); print $PostTitle. "..."; } else { print $info['post_title']; } Print "</a> <font color=#666666><i> - posted on "; $date = date('j M \'y', strtotime($info['post_date'])); Print $date; Print "</i>"; } ?> I have a small script that prints the contents of a log on my server but it's removing tags from the output. An example would be: <username> data here is being printed as: data here removing: <username> I do not want it to strip these out of the output. How do I avoid this? Code: [Select] <? $cmd = "tail -5 /opt/mserver/server.log"; exec("$cmd 2>&1", $output); foreach($output as $outputline) { print ("$outputline\n"); } ?> Hi all, I just managed to make a little mod_rewrite rule which manages to interpret url's without the extension and calls the right file with the extension (ie. /articles calls articles.php) . But now i am left with another question which i am almost certain has nothing to do with mod_rewrite, but rather with a php trick. In case someone enters on my site www.mydomain.com/laalalalala.php How do i get rid of that last part(the extension for example)? Do i maybe have to get the GET['var'] and run it through a regex and reload the page with the stripped version? That was all i could think off but it sound so complicated. if anyone has an idea i would love to hear it cheers! P.s.s if anyone want's that rewrite rule, let me know. I saw quite some people on the internet looking for it i'm having problems with apostrophes causing an error on my contact form. I've tried stripslash and also str_replace but i can't get it to work. what am i doing wrong? thanks Code: [Select] <?php if(isset($_POST['email'])) { // EDIT THE 2 LINES BELOW AS REQUIRED $email_to = "test@test.com"; $email_subject = "test"; function died($error) { // your error code can go here echo "We are very sorry, but there were error(s) found with the form you submitted. "; echo "These errors appear below.<br /><br />"; echo $error."<br /><br />"; echo "Please go back and fix these errors.<br /><br />"; die(); } // validation expected data exists if(!isset($_POST['contact_name']) || !isset($_POST['last_name']) || !isset($_POST['email']) || !isset($_POST['telephone']) || !isset($_POST['comments'])) { died('We are sorry, but there appears to be a problem with the form you submitted.'); } foreach($_POST['check'] as $value) { $check_msg .= "Checked: $value\n"; } $contact_name = str_replace("'", "&#039;", $contact_name); $contact_name = $_POST['contact_name']; // required $last_name = $_POST['last_name']; // required $email_from = $_POST['email']; // required $telephone = $_POST['telephone']; // not required $comments = $_POST['comments']; // required $error_message = ""; $email_exp = '/^[A-Za-z0-9._%-]+@[A-Za-z0-9.-]+\.[A-Za-z]{2,4}$/'; if(!preg_match($email_exp,$email_from)) { $error_message .= 'The Email Address you entered does not appear to be valid.<br />'; } $string_exp = "/^[A-Za-z .'-]+$/"; if(!preg_match($string_exp,$contact_name)) { $error_message .= 'The First Name you entered does not appear to be valid.<br />'; } if(!preg_match($string_exp,$last_name)) { $error_message .= 'The Last Name you entered does not appear to be valid.<br />'; } if(strlen($comments) < 2) { $error_message .= 'The Comments you entered do not appear to be valid.<br />'; } if(strlen($error_message) > 0) { died($error_message); } $email_message = "Form details below.\n\n"; function clean_string($string) { $bad = array("content-type","bcc:","to:","cc:","href"); return str_replace($bad,"",$string); } $email_message .= "Contact Name: ".clean_string($contact_name)."\n"; $email_message .= "Agency/Company Name: ".clean_string($last_name)."\n"; $email_message .= "Email Address: ".clean_string($email_from)."\n"; $email_message .= "Dates Required: ".clean_string($telephone)."\n"; $email_message .= "Type Required: ".clean_string($check_msg)."\n"; $email_message .= "Any other info: ".clean_string($comments)."\n"; // create email headers $headers = 'From: '.$email_from."\r\n".

'X-Mailer: PHP/' . phpversion(); @mail($email_to, $email_subject, $email_message, $headers); ?> thanks <?php } ?> Hi All, Hope you can help, I'm having problems with the strip_tags code, I'm having problems getting it to work with certain tags, the code below shows my issue: $print_description = <span style="color: #ff99cc; font-size: large">4 x BLUE handmade clay feet</span> $print_description = strip_tags($print_description); //remove html because of danger of broken tags I've cut down the code to show the problem. So I want to strip the Span tags; the problem I am having is as soon as you have a style attribute with more than one attribute and you use a ; symbol strip_tag will strip the entire content of the <span>AND ALL THE TEXT IN THE MIDDLE</span>. I want to just be left with '4 x BLUE handmade clay feet' If I take the ; out and just have one style it works fine. I am using tiny_MCE so don't have the option not to use what it makes me use. I've searched the net and have tried a few things to make it work but now I'm at a loss. Any help would be gratefully received. In querying my database, I'm Selecting nameFirst and nameLast, and it produces a name like Joe Smith. I'm trying to match a photo with the name. Right now I'm uploading photos into a folder naming the file (e.g. SmithJoe.jpg). For reasons that involve writers being able to upload and access photos, I'm trying to use an image plugin. When uploading photos, it strips capital letters, so SmithJoe,jpg goes in as smithjoe.jpg, and it's not matching my database query. Here is the code I'm working with that works quite well with this one exception: $query = 'SELECT * FROM wp_playerRank'; $results = mysql_query($query); while($line = mysql_fetch_assoc($results)) { if ($line['wpID'] == $wp_tagID) { echo '<div class="player">'; // Here is the code that produces the image. I need to get rid of capital letters for ease of use echo '<div><img src="/wp-content/uploads/' . $line['nameLast'] . $line['nameFirst'] . '.jpg"></div>'; echo '<div class="playerData">' . $line['height'] . ' '; if ($line['position'] == 'PG') {echo 'Point Guard';} elseif ($line['position'] == 'SG') {echo 'Shooting Guard';} elseif ($line['position'] == 'SF') {echo 'Small Forward';} elseif ($line['position'] == 'PF') {echo 'Power Forward';} elseif ($line['position'] == 'C') {echo 'Center';} echo '</div>'; echo '<div class="playerData">' . $line['hschool'] . '</div>'; echo '<div class="playerData">' . $line['summer'] . '</div>'; echo '<div class="playerData">Class of ' .$line['year'] . '</div>'; if ($line['committed'] == 'y') { echo '<div> <br>Committed to <strong>'. $line['college'] . '</strong></div> ';} } } hi everyone, did not know what to make the subject, but here is what I want to do: I have a string, which gets returned to me from a linux app on my server, it looks something like this: Code: [Select] <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML> <HEAD> <META HTTP-EQUIV="CONTENT-TYPE" CONTENT="text/html; charset=utf-8"> <TITLE> </TITLE> <META NAME="GENERATOR" CONTENT="OpenOffice.org 3.2 (Linux)"> <META NAME="AUTHOR" CONTENT="Administrator"> <META NAME="CREATED" CONTENT="20110106;14170000"> <META NAME="CHANGEDBY" CONTENT="HOD"> <META NAME="CHANGED" CONTENT="20110522;16540000"> <STYLE TYPE="text/css"> <!-- @page { margin: 0.26in } P { margin-bottom: 0.15in; direction: ltr; color: #000000; line-height: 0.15in; text-align: justify; widows: 2; orphans: 2 } P.western { font-family: "Arial", sans-serif; font-size: 10pt; so-language: en-US } P.cjk { font-family: "Batang", "바탕", serif; font-size: 10pt } P.ctl { font-family: "Times New Roman", serif; font-size: 10pt; so-language: ar-SA } A:link { color: #0000ff } --> </STYLE> </HEAD> <BODY LANG="en-US" TEXT="#000000" LINK="#0000ff" DIR="LTR" STYLE="border: 5.05pt double #000000; padding: 0.67in 0.92in"> <P>I want this and the tags around it, just not the html, head, body and their closing tags.</P> </BODY> </HTML> within the body, the tags are each styled for example: <p style="color: red"></p> so I cannot just get rid of all html, I want to get only all the content within the body tags, but without the body tags obviously strip_tags does not work as i need, I only want to strip certain tags. If someone can help me with this i will much appreciate it. I am asking out of curiosity, how does this problem usually get solved, when using a tag system to sort content, and users enter similar tags. For example: flower and flowers... which means the difference between singular and plural. Judging by other sites which are around, this problem is not solved at all, they simply let you add as many tags as you want and then rank the most used tags, it indeed is a solution, but seems more like a walk-around solution to me. Any ideas how somebody could approach to solve this one? EDIT: My suggestion would be an analysis function, which analyzes the entered tag and then suggests the user that similar tags have been already entered and perhaps he wants to choose one of those which have been already entered. This does work though with a high traffic websites what can happen is the following: php and php5 You can end up with two similar tags which are both widely used though have different meanings to the user base. This one could be solved by simply prohibiting similar tags with little additions or changes, and so to speak "forcing" the user to choose something which is already there. May be a way, though it can turn out as a bad solution as well. Do anyone know how i can put the html tags in the same line as the other html tags? Here's an example: Code: [Select] Images | Link | Delete | Enabled On my code, it break the tags to the new line without put on the same line as the other tags. Here's the code: Code: [Select] [code]<?php session_start(); define('DB_HOST', 'localhost'); define('DB_USER', 'myusername'); define('DB_PASSWORD', 'mypass'); define('DB_DATABASE', 'mydbtable'); $errmsg_arr = array(); $errflag = false; $link = mysql_connect(DB_HOST, DB_USER, DB_PASSWORD); if(!$link) { die('Failed to connect to server: ' . mysql_error()); } $db = mysql_select_db(DB_DATABASE); if(!$db) { die("Unable to select database"); } function clean($var){ return mysql_real_escape_string(strip_tags($var)); } $username = clean($_GET['user']); $password = clean($_GET['pass']); if($username == '') { $errmsg_arr[] = 'username ID missing'; $errflag = true; } if($password == '') { $errmsg_arr[] = 'PASSWORD ID missing'; $errflag = true; } if($errflag) { $_SESSION['ERRMSG_ARR'] = $errmsg_arr; echo implode('<br />',$errmsg_arr); } else { $qry="SELECT * FROM members WHERE username='$username' AND passwd='$password'"; $result=mysql_query($qry) or die('Error:<br />' . $qry . '<br />' . mysql_error()); if(mysql_num_rows($result) > 0) { $qrytable1="SELECT images, id, public FROM members WHERE username='$username'"; $result1=mysql_query($qrytable1) or die('Error:<br />' . $qry . '<br />' . mysql_error()); while ($row = mysql_fetch_array($result1)) { echo '<p id="images"> <a href="images.php?id='.$row['id'].'">Images</a></td> | <a href="http://' . $row["links"] .

Code: [Select] <b>Classic Quote from movie</b> and I retrieve it into a variable called $text, how do I properly echo that so that it keeps the bold tags and actually display the text "Classic quote from movie" in BOLD? I'm doing something wrong somewhere along the line (simply doing "echo $text;") because it displays on the page as... Code: [Select] <b>Classic Quote from movie</b> Instead of... Classic Quote from movie Any info on properly storing and echoing back HTML would be very appreciated. I have just been given some code that is live on a web site. I pulled it down to my local linux machine and the php will not run. I have worked out the issue the php tags are <? scripting ?> it is missing the php. I have a couple of questions how do I get my local linux machine get <? scripting ?> this to work and I have a lot of code that is like this and I am sure that it is no longer secure is this right? alright I've seen and use Code: [Select] <?php Code: [Select] <?but never before do I recall seeing Code: [Select] <?= Nor do I even know where to look that up, so.. anyone ever see that used before, if so, any insight as to why someone would choose that? Hi guys, i have not started this as of yet, however i will be given a project to make a micro-blogging website similar to that of Twitter or Facebook but obviously on a much smaller scale I have been searching on google however i have not found anything. Maybe i haven't been using the right words in my query, not sure :-/ I have been trying to do some research, however i can't seem to find how to incorporate @ tags found in Twitter / Facebook. e.g. If i want to tag a person in a Status Update: Hey @John Smith, Football in the park at 3pm? If anyone is able to help i would be grateful Thank You Hello i said to replace the short php tags (<??>) with long php tags (<?php ?>) but it is giving me Parse errors -.- the parse error apears if i have <?php//NOTE ?> With <?//NOTE?> Is all ok and it dosnt give me that error .. could anyone please tell me why dos it give the error and some more details about the tags etc Thanks in advance How does PHP continuity exist in different php tags? for example, if i connect to a database in a header, and close the tag, can I still work off of the same database in another tag? I found this code on a website: <?php //Reads ID3v1 from a MP3 file and displays it $mp3 = "1.mp3"; //MP3 file to be read //make a array of genres $genre_arr = array("Blues","Classic Rock","Country","Dance","Disco","Funk","Grunge", "Hip-Hop","Jazz","Metal","New Age","Oldies","Other","Pop","R&B", "Rap","Reggae","Rock","Techno","Industrial","Alternative","Ska", "Death Metal","Pranks","Soundtrack","Euro-Techno","Ambient", "Trip-Hop","Vocal","Jazz+Funk","Fusion","Trance","Classical", "Instrumental","Acid","House","Game","Sound Clip","Gospel", "Noise","AlternRock","Bass","Soul","Punk","Space","Meditative", "Instrumental Pop","Instrumental Rock","Ethnic","Gothic", "Darkwave","Techno-Industrial","Electronic","Pop-Folk", "Eurodance","Dream","Southern Rock","Comedy","Cult","Gangsta", "Top 40","Christian Rap","Pop/Funk","Jungle","Native American", "Cabaret","New Wave","Psychadelic","Rave","Showtunes","Trailer", "Lo-Fi","Tribal","Acid Punk","Acid Jazz","Polka","Retro", "Musical","Rock & Roll","Hard Rock","Folk","Folk-Rock", "National Folk","Swing","Fast Fusion","Bebob","Latin","Revival", "Celtic","Bluegrass","Avantgarde","Gothic Rock","Progressive Rock", "Psychedelic Rock","Symphonic Rock","Slow Rock","Big Band", "Chorus","Easy Listening","Acoustic","Humour","Speech","Chanson", "Opera","Chamber Music","Sonata","Symphony","Booty Bass","Primus", "Porn Groove","Satire","Slow Jam","Club","Tango","Samba", "Folklore","Ballad","Power Ballad","Rhythmic Soul","Freestyle", "Duet","Punk Rock","Drum Solo","Acapella","Euro-House","Dance Hall"); $filesize = filesize($mp3); $file = fopen("1.mp3", "r"); fseek($file, -128, SEEK_END); $tag = fread($file, 3); if($tag == "TAG") { $data["song"] = trim(fread($file, 30)); $data["artist"] = trim(fread($file, 30)); $data["album"] = trim(fread($file, 30)); $data["year"] = trim(fread($file, 4)); $data["comment"] = trim(fread($file, 30)); $data["genre"] = $genre_arr[ord(trim(fread($file, 1)))]; } else die("MP3 file does not have any ID3 tag!"); fclose($file); while(list($key, $value) = each($data)) { print("$key: $value<br>\r\n"); } ?> How would i edit this to look in a directory, and sub-directories and get information for every mp3 and add the data to a mysql database (the latter i can do easily) I am tweaking a function which takes data that was entered into a Form TextArea and wraps each paragraph with <p></p> tags so things are properly marked up. It seems to be working okay, except for two annoying things... 1.) When I go to View ---> Source, I do NOT want to see paragraph after paragraph all on the same line. I tried adding a \n into the preg_replace but it is adding an extra carriage return in the output. 2.) Right now, if my code sees 2 \n's it will convert that to "</ p><p>", which is fine. However it does the same thing if there are 20 \n's which is technically wrong, because maybe someone wanted the extra 18 carriage returns between their paragraphs?! For example, in the line below "I decided to start..." that line should get wrapped in <p></p> and then there should be a <br /><br /> because the User added two *extra* carriage returns, and then the next line "My boss is a jerk..." should get wrapped in <p></p> because it is also a paragraph. I'm sure this one is impossible to do, but the end goal is simple... Regardless of how many carriage returns there are between blocks of text, the blocks of text should first get wrapped in <p> </p> but then any additional line spacing should be preserved. Hope that makes sense?! Here is the code I am working with... $text="I decided to start my own business because I want to be my own boss! My boss is a jerk and never appreciates anything that I do for him, so why put up with the abuse?! He takes me for granted and doesn't appreciate all of my talents. Running my own business will give me a chance to do things as I see fit... Line One Line Two Line Three Line Four Line Eight"; $text2 = htmlentities($text, ENT_QUOTES); function nl2p($string, $line_breaks = true) { // Remove existing HTML formatting to avoid double tags. //^ $string = str_replace(array('<p>', '</p>', '<br>', '<br/>'), '', $string); // Replace Carriage Return with Empty String. // Replace multiple Newlines with closing & opening paragraph tags. // Replace single Newline with break tag. if ($line_breaks == true) { return '<p>'.preg_replace(array("#\r#","#\n{2,}#", "#\n#"), array("","</p><p>", "<br />\n"), $string).'</p>'; }else{ return '<p>'.preg_replace("#\n#", "</p><p>", trim($string)).'</p>'; } } echo nl2p($text2, TRUE); Oh, btw, as you can see, adding a \n after the line break (i.e. "<br />\n") actually added the line break in my Source as I wanted. It is just when you add a \n in between the paragraphs that my code misbehaves (i.e. "</p>\n<p>"). Can these two problems be fixed?? Thanks, Debbie This works fine with a couple of exceptions... how do I add zero borders, alt tags etc... plus it is displaying like this htt:/// in the URL...
