Spry no hyperlink validation

[songweaver1981]

I am using spry for validation for my contact form. I am getting a lot manual spam on my site. I have integrated reCaptcha for spam bots, but doesn't prevent manual spam. I wanted to alter my SpryVaildationTextarea.js file to prevent submission when someone inserts a hyperlink. I am not a js expert so please be kind and simple. Here is my validation js file code:

Okay.  I'll be the one to jump on the grenade.

I hate to say this, because it may come off as trite.  I'm not trying to be disrespectful, but it needs to be said.

Stop using Spry.

It's defunct.  It's old.  I know there are lots of developers who still use it, but that's no excuse.  There are other, better, more reliable and efficient methods to get the same functionality.  jQuery, jQuery UI, MooTools.  I do form validation in vanilla Javascript.  To remove links in your form inputs, use a Regular Expression to find and remove all HTML tags and their content, or replace them with something like [Invalid characters removed].

Spry was great when it first came out.  Not so much, anymore.

V/r,

^ _ ^

[songweaver1981]

I am considering that in the future, but I am looking for a quick fix. Surely there is a way to do it.

[songweaver1981]

Anybody?

[WolfShade]

I would like to help, but I have never used Spry, even though it was popular when I first started working in web (2001).  And I'm not sure how many people on this forum know Spry.

V/r,

Using the out-of-the-box SpryValidation will not do what you want, see Adobe Labs - Spry Validation Textarea Overview

Remember that Spry is client side code which can easily be bypassed by turning the browser JavaScript off. In cases like this, you are better off have server-side validation. The PHP code (if that is your server) would look like

<?php

$text = 'this is just a link https://forums.adobe.com/message/10303083#10303083';

$regex = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";

if(preg_match($regex, $text, $url)) { // $url is now the array of urls

  // here you should check $url content and length

  echo $url[0]; // the first one in this case

}

else {

  echo 'no urls found';

}

If you insist on client-side code, Google the subject using JavaScript/jQuery.

[songweaver1981]

Where would I put this php code?

[BenPleysier]

In the action code for the form.

If you show us the code, we may be able to help you further.

[songweaver1981]

Just to let you know I utilized the php script FormToEmail for the form. I do not know a whole lot about php, but I used Form@Mail because it was the easiest to implement, and it works except for keeping spammers from manually filling out the form. I will attach the code I have for the form along with the code in FormToEmail script. Perhaps something just needs to be added in there?

FormToEmail DESCRIPTION
FormToEmail is a contact-form processing script written in PHP. It allows you to place a form on your website which your visitors can fill out and send to you.  The contents of the form are sent to the email address (or addresses) which you specify below.  The form allows your visitors to enter their name, email address and comments.  The script will not allow a blank form to be sent.
Your visitors (and nasty spambots!) cannot see your email address.  The script cannot be hijacked by spammers.
When the form is sent, your visitor will get a confirmation of this on the screen, and will be given a link to continue to your homepage, or other page if you specify it.
Should you need the facility, you can add additional fields to your form, which this script will also process without making any additional changes to the script.  You can also use it to process other forms.  The script will handle the "POST" or "GET" methods.  It will also handle multiple select inputs and multiple check box inputs.  If using these, you must name the field as an array using square brackets, like so: <select name="fruit[]" multiple>.  The same goes for check boxes if you are using more than one with the same name, like so: <input type="checkbox" name="fruit[]" value="apple">Apple<input type="checkbox" name="fruit[]" value="orange">Orange<input type="checkbox" name="fruit[]" value="banana">Banana
** PLEASE NOTE **  If you are using the script to process your own forms (or older FormToEmail forms) you must ensure that the email field is named correctly in your form, like this for example: <input type="text" name="email">.  Note the lower case "email".  If you don't do this, the visitor's email address will not be available to the script and the script won't be able to check the validity of the email, amongst other things.  If you are using the form code below, you don't need to check for this.
This is a PHP script.  In order for it to run, you must have PHP (version 4.1.0 or later) on your webhosting account, and have the PHP mail() function enabled and working.  If you are not sure about this, please ask your webhost about it.
SETUP INSTRUCTIONS
Step 1: Put the form on your webpage
Step 2: Enter your email address and (optional) continue link below
Step 3: Upload the files to your webspace
Step 1:
To put the form on your webpage, copy the code below as it is, and paste it into your webpage:
<form action="FormToEmail.php" method="post">
<table border="0" style="background:#ececec" cellspacing="5">
<tr align="left"><td>Name</td><td><input type="text" size="30" name="name"></td></tr>
<tr align="left"><td>Email address</td><td><input type="text" size="30" name="email"></td></tr>
<tr align="left"><td valign="top">Comments</td><td><textarea name="comments" rows="6" cols="30"></textarea></td></tr>
<tr align="left"><td> </td><td><input type="submit" value="Send"><font face="arial" size="1">  <a href="http://FormToEmail.com">PHP Form</a> by FormToEmail.com</font></td></tr>
</table>
</form>
Step 2:
Enter your email address.
Enter the email address below to send the contents of the form to.  You can enter more than one email address separated by commas, like so: $my_email = "info@example.com"; or $my_email = "bob@example.com,sales@example.co.uk,jane@example.com";
*/
$my_email = "lwcc@lwcchurch.org";
/*
Optional.  Enter a From: email address.  Only do this if you know you need to.  By default, the email you get from the script will show the visitor's email address as the From: address.  In most cases this is desirable.  On the majority of setups this won't be a problem but a minority of hosts insist that the From: address must be from a domain on the server.  For example, if you have the domain example.com hosted on your server, then the From: email address must be something@example.com (See your host for confirmation).  This means that your visitor's email address will not show as the From: address, and if you hit "Reply" to the email from the script, you will not be replying to your visitor.  You can get around this by hard-coding a From: address into the script using the configuration option below.  Enabling this option means that the visitor's email address goes into a Reply-To: header, which means you can hit "Reply" to respond to the visitor in the conventional way.  (You can also use this option if your form does not collect an email address from the visitor, such as a survey, for example, and a From: address is required by your email server.)  The default value is: $from_email = "";  Enter the desired email address between the quotes, like this example: $from_email = "contact@example.com";  In these cases, it is not uncommon for the From: ($from_email) address to be the same as the To: ($my_email) address, which on the face of it appears somewhat goofy, but that's what some hosts require.
*/
$from_email = "";

At the top of FormToEmail.php, I would put

<?php 

  error_reporting(E_ALL ^ E_NOTICE);

$regex = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";

if(preg_match($regex, $_POST['comments'], $url)) {

  echo "URL's are not allowed";

  exit();

}

That way, when a URL is sent, you interrupt the process at the start.

It does not let the form submit at all, even if there is no link in the box.

[songweaver1981]

Anyone?

[BenPleysier]

The problem has to be elsewhere in the script. I have removed all of the script in FormToEmail.php and replaced it with

<?php  
error_reporting(E_ALL ^ E_NOTICE);  
$regex = "/(http|https|ftp|ftps)\:\/\/[a-zA-Z0-9\-\.]+\.[a-zA-Z]{2,3}(\/\S*)?/";
if(preg_match($regex, $_POST['comments'], $url)) {
  echo "URL's are not allowed";
} else {
  echo "OK, No URL's";
}

You will see that it works.

Edit: I also had to remove the SpryValidation stuff from the form because I had no support files.

[songweaver1981]

I put in in the middle of the other if statements and it worked! Thanks a bunch! For some reason it would not work at the top right after the

1. <?php   
2. error_reporting(E_ALL ^ E_NOTICE);
