PHP - Removing All Unwanter Charachers But A-z And A-z
In my form people are being asked for name which gets entered into database. How do I take my "$_POST[name]" and remove all characters but A-Z and a-z. I do not want ~`!@#$%^&*()_-+={[}]|\"':;?/>.<, there at all or numbers for that matter.
I have been paying with stripslashes and strip_tags but they don't fully cut it Thanks Similar TutorialsI am trying to filter characters that get submitted into forms and than database. I have been paying with trim function $string = $_POST[name]; $newstring = trim($string,"W"); echo "$newstring"; but it does not seem to do what I really need. If I enter name World I do get "orld" back, but what if I want to filter out W (or w) and L (or l) to get "ord". I am mainly going after removing ' " ; : . > , < - _ ( ) * & ^ % $ # @ ! \ | / ? I know there is a different way to do it, but it has been long tome since I have seen it, and I do not know where. Thanks for your help Hi All,
I'm trying to return HTML page contains the Russian characters sent as POST variables and also static data as part of HTML result.
I'm not able to put it work together.
If I set windows-1251 - the static data displayed incorrectly.
If I set UTF-8 - the dynamic (POST) data displayed incorrectly
Any thoughts?
Thank you very much in advance,
Evgeny
Following is the simple HTML example and also Fiddler request example
<?php Hey guys, im using UNIX time and trying to figure out how to remove the leading 0 when it shows the hour. "07:06 am" to make it read "7:06 am" manual says i need to use %i with strftime. So I guess Im suppose to be removing the zero before the date format? which is why strftime isnt working after the date function. Or is there a way to do this in the date function. $time = 1327493219; date_default_timezone_set('UTC'); $user_offset = date('h:i a M/d', $time); echo "<td>". strftime("%l",$user_offset) ."</td>"; Hy guys I try to rebuild a PTC site The thing is when the member is click on the ad, they get money after x sec.

What I want to do is simple: The string "this_is_an_example.php" should return "this_is_an_" while: "this_is_an_example_filename.php should return "this_is_an_example_" Is there a simple function which can cut off the part after the last _ ? I have been looking and trying several functions, but can't seem to find the right one for this. (the last _ being cut off of course wouldn't be a problem I couldn't live with :-) ) Any help will be greatly appreciated! Hey guys. How do you remove a specific element from an array? Lets say I have a string like this: $list = "guy,girl,boy,man,woman,lady"; Then I use explode to break it up into an array by commas: $listArray = explode(",",$list); Now $listArray contains everything. Now if I wanted to delete something specific from that array, how would I do that? So for example, I want to delete "man" out of the array. How do I do that without know its key? Hello Everyone, I am working on a project I pull the field names from the database. I am trying to remove the underscore (_) when the field name is displayed. Does anyone know how I would do that? Here is the code that I am working with Code: [Select] $i = 0; while ($i < mysql_num_fields($fieldnamesquery_result)) { $meta = mysql_fetch_field($fieldnamesquery_result, $i); if (!$meta) { echo "No information available"; } $meta = str_replace("_", " ", $meta); $tablecolumn .= "<p>" . $meta->name . ":<input type='text' name='" . $meta->name . "' id='" . $meta->name . "' /></p>"; $i++; Hello, I have a field in which when a user types something into it, it saves it into a table in my SQL. But is it possible to remove a particular phrase from the field if the user enters it. Example: I have a text field that says 'please enter your website domain here'. The user then enters 'www.domain.com'. Is it possible for PHP to remove the 'www.' and only save the 'domain.com' to my SQL (bearing in mind that not all users may enter www.) Here is the code for the text field: Code: [Select] <input name="website_name" type="text" class="text-box" id="website_name" value="<?php echo $website_name; ?>" size="24" /> Here is the code for the _POST: if(isset($_POST['send'])) { $database->updateUserField($session->username, "website_name", $_POST['website_name']); } (the code so far all works fine - I just want to add an extra 'variable', if you will, to the code) Thanks for your help!! I'm new in php and I don't have knowledge of php.
I just want to know, whenever we download file from server to Desktop through FTP, there are whitespaces occuring in files.
Like html websites, we always remove whitespaces whenever we upload the file to server after editing it. Is this step necessary for php websites also? If necessary then how to do it?
In my php and html code I have lots of whitespace and line breaks between the <tags>. How I can remove all useless whitespace and linebreaks without altering the main text and codes? Hey Guys, I have a html page and I want to set some markers or tags so when I submit the page, I can strip out content between those tags. For example something like <!-- STRIP --> .. html content la la la.. <-- END STRIP --> or have a div with a class <div class="strip"> ... html content la la la </div> A. Which would be the best one? B. How can I do this with ereg exp? Say i wanted to make a list with only female names and i wrote the whole file for it but it kept showing both Male and Female names how would i remove the male names from the list without deleting them out of the SQL? I wish i knew how to word this better for what I'm looking for.... ----------------------------------------------Don't know if you need this---------------------------------------------- MySQL Server: Localhost via UNIX socket Server version: 5.0.91 Protocol version: 10 User: tpkrpgn1@localhost MySQL charset: UTF-8 Unicode (utf8) Web server cpsrvd 11.28.64 MySQL client version: 5.0.91 PHP extension: mysql phpMyAdmin Version information: 3.3.8.1 ----------------------------------------------Don't know if you need this---------------------------------------------- Also is there a way to delete previous posts? I'm trying to remove a dash at the end of a title, for the times when a dash appears there (which isn't always). Since my titles are always different lengths, I don't think substr will work. How can I code the following... If $title ends with '-', replace with '' Thanks! |
