PHP - How To Simply Remove Characters And Spaces From A Form Text Box.
Hi all! I am building a website, and the users can create a pet name. I only want them to be able to use letters, numbers and underscores in the names. How can I do this? Thanks! I would also be using this for the usernames as well. Here is my pet creation code:
adopt.php: Code: [Select] <?php session_start(); include("config536.php"); ?> <html> <head> <link rel="stylesheet" type="text/css" href="style.css" /> </head> <?php if(!isset($_SESSION['username'])) { echo "<banner></banner><ubar><a href=login.php>Login</a> or <a href=register.php>Register</a></ubar><content><center><font size=6>Error!</font><br><br>You are not Logged In!

Guys: What is the way to remove white spaces in front of a form entry ? Should I use regular expression for this ? Thanks. hi, i have a search engine that searches keywords in mysql database... i have a simple form but if someone enters a load of spaces it displays the whole database contents.. also i wanna remove any words less then 3 characters being searched for.. i have (strlen($search)<=3) what else should i add?? cheers Am looking forward to removing all the numeric characters upto and including the leading "/" in 90/_featuredarticles/2011/12 Regards Hi, Im looking at using a statement like this to remove all text characters from a string. $outgoing = substr_replace($incoming,"",-1); The string is a currency that has a currency symbol in the beginning of the string, like "R500.00" I would like to remove the R, so it is just a numeric value... Please can you help me with any ideas on how to get this going? Been reading so much and its all confused me too badly. Regards, Chris This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=356719.0 This topic has been moved to PHP Regex. http://www.phpfreaks.com/forums/index.php?topic=322184.0 I have sen this function before but can not remember what it is or how to code it. It allows you remove only defined characters from the end of the string. I am not looking to replace any occurrence anywhere in the phrase, just the end. For example lets say I want to remove"ld!" from phrase "Hello World!" That function would return "Hello Wor" Thanks I have a form with some dropdownlist that get populated dynamically(depends on what the user chooses) with jquery and an xml file. In the form I have a button that takes the info and populates another form with the values of the ddl. I have coded script which populates the second form with jquery and the name of each input get dynamically added like so: Code: [Select] <input type="text" value="'+model+'" name="Model_'+model+'" id="'+model+'" readonly size="'+model.length+'" /> <input type="text" value="'+model+'" name="Model'+model+'" id="'+model+'" readonly size="'+model.length+'" />> <input type="text" value="'+color+'" name="Color'+color+'" id="'+color+'" readonly size="'+color.length+'" /> <input type="text" value="'+part+'" name="Part'+part+'" id="'+part+'" readonly size="'+part.length+'" /> <input type="text" value="$'+price+'" name="Price'+price+'" id="'+price+'" readonly size="'+price.length+'" /> <input type="text" value="'+qty+'" name="Quantity'+qty+'" id="'+qty+'" readonly size="'+qty.length+'" /> <input type="text" value="'+total+'" name="Total'+total+'" id="'+total+'" readonly size="'+total.length+'" /> What I want to do is grab the name of the element and remove the underscore and everything else form rileft to right so I am left with just the word before the underscore. I tried using substr($key,0,-28) but that wont work since everything after the underscore will have a different length. I was wondering if there is a way i can keep everything before the underscore and remove the underscore and everything after that. Thanks in advance for any input I get. I am wanting to display large text blocks from a database but i would like to stop the text if its longer than 600 characters and display Read more... as a link. Can someone please help me? This is an easy question for those fluid in PHP and one area I struggle in.
I have this variable.
$downloadedmetar1windThat outputs this.... S (180 degrees) at 26 MPH (23 KT) I am trying to strip away the (180 degrees) and the (23 KT) so it just reads S at 26 MPH This is what I have done but it isn't removing the brackets and the contents between it.
$wind = preg_replace('/([\s.]\([0-9-]+\))/', '', $downloadedmetar1wind);

I have a question,
I have a fully working PHP mail form, but I can't seem to find one problem.
I thought it had something to do with the data cleansing like trim, htmlspecialcharacters and stripslashes, but unfortunately that wasn't.
My form has to be able to process characters like é è á ó etc.
Just that now when you fill those characters in it shows some weird code in the mail.
(é becomes é in the mail) and this is highly inconvenient.
Could any1 tell me how I can fix this?
this is the PHP code for my form:
<?php

{
function test_input($data) {
$data = trim($data);
$data = stripslashes($data);
