Hi all

I'm quite a competent PHP coder but where it comes to preg_match I prefer to be ignorant, because I can't get my head around the patterns.

Basically, I'm working with a script that someone else has written, and I'm coming across problems because the URL that is being validated sometimes has curly brackets '( )' in it (these are image file names generated by an internal system). I have the pattern, how do I modify this to allow curly brackets? On some occasions, the urls have just the opening or just the closing, so its never the complete set.

if someone could give me an indication with this, because I'm clueless! Thanks in advance!

Ste

pattern:
Code: [Select]
$pattern = '/^(([\w]+:)?\/\/)?(([\d\w]|%[a-fA-f\d]{2,2})+(:([\d\w]|%[a-fA-f\d]{2,2})+)?@)?([\d\w][-\d\w]{0,253}[\d\w]\.)+[\w]{2,4}(:[\d]+)?(\/([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)*(\?(&?([-+_~.\d\w]|%[a-fA-f\d]{2,2})=?)*)?(#([-+_~.\d\w]|%[a-fA-f\d]{2,2})*)?$/';

Hi,

I want to separate out the file name from an image url. Not sure the best way to do it? I want to basically select all text after the last / slash. eg - image.jpg would be the result from http://www.google.com/images/image.jpg

What's the best way to do it?

Cheers

Rob

Hi, I am having a pretty difficult time getting files to upload to my server that have a Single Quote in the file name.
Example:

myfile's.pdf

I need to strip the file name of the quote before it uploads to the server.
I currently am using SWFUpload and this is the bit of code that was included with it.

I need to modify it to remove the single quotes as well. Been hammering my head over this all day.


$file_name = preg_replace('/[^'.$valid_chars_regex.']|\.+$/i', "", basename($_FILES[$upload_name]['name']));
if (strlen($file_name) == 0 || strlen($file_name) > $MAX_FILENAME_LENGTH) {
HandleError("Invalid file name");
exit(0);
}


thanks

Hello, I have problem durring binding update query. I can't find what is causing problem.

public function Update(Entry $e)
    {
        try
        {
            $query = "update entry set string = $e->string,delimiter=$e->delimiter where entryid= $e->id";
            $stmt = $this->db->mysqli->prepare($query);
            $stmt->bind_param('ssi',$e->string,$e->delimiter,$e->id);

            $stmt->close();
           

        }
        catch(Exception $ex)
        {
            print 'Error: ' .$ex->getMessage();
        }
    }

When I run function update I'm getting next error:Warning: mysqli_stmt::bind_param(): Number of variables doesn't match number of parameters in prepared statement   Can you help me to solve this problem ?

It will display what it's meant to display if I have a username that is in the database, however if the username doesn't exist in the database, it's meant to say "Username not found!. Please try again" and show the search box again. However if I put in a Username that doesn't exist. I get a blank page (well at the top of the page the page I do get Hello Howlin1 Logout)

What am I doing wrong?

Well I guess I'll jump right into the code..


The function:
function isIpaddr ($ipaddr)
{
if (ereg("^([0-9]{1,3}).([0-9]{1,3}).([0-9]{1,3}).([0-9]{1,3})$", $ipaddr, $digit))
{
if (($digit[1] <= 255) && ($digit[2] <= 255) && ($digit[3] <= 255) && ($digit[4] <= 255))
{
return TRUE;
}
}

return FALSE;
}

The loop and IF statement:
if($_POST['submit_multiple']) {
$SubmittedIPs = split("[\n|\r|,|-]", $_POST['IPAddresses']);
foreach($SubmittedIPs as $IP) {
trim($IP);
if(isIpaddr($IP)) {
echo $IP." = ".gethostbyaddr($IP)."<br />";
} else {
echo "Invalid IP Address<br />";
}
}
}


There's my relevant code..

Now the only problem so far is that I am getting this:
Quote

12.34.56.78 = 12-34-56-78.test.hostname.com
Invalid IP Address
12.34.56.78 = 12-34-56-78.test.hostname.com
Invalid IP Address
12.34.56.78 = 12-34-56-78.test.hostname.com

(The IPs and Hostnames are obviously fake..)

The problem is that they are valid IP addresses and I've done a few checks to see what's wrong. I've checked the array and it is working fine by splitting up a textbox into an array of IPs and the IPs are fine inside the array. I then tested the script by echoing the output of just the function with each IP, I got all "1"s (TRUE).

I just can't figure out why it's displaying both parts of the if statement..

Thanks for any help!

So basically I've been experimenting with setting cookies and sessions. The code in my header file will display a login if there is no $_SESSION['username']. However, the else statement verifies that there is, and echo's "hello." My problem lies in the else statement, when the login form disappears, but nothing in the else statement appears. Here's the code, I feel like I am missing something obvious.

Code: [Select]
<?php
if (!isset($_SESSION['username'])){
 echo "<li><a href='register.php'>Register</a></li>";
 echo "</ul>";
  echo "
    <table>  
    <tr>
    <form name='login' method='post' action='login.php'>
    <tr><td>Username</td> <td><input type='text' name='username'></td></tr>
    <tr><td>Password</td> <td><input type='password' name='password'></td></tr>
    <tr><td><input type='submit' name='submit' value='Login'></td></tr>
    <tr><td><input type='checkbox' name='rememberme' value='remember'> Remember</td></tr>
    </form>
    </table>
";
}else{
echo "hello";
}

?>

Thanks in advance

I am creating a class alumni web and ask a question tha requires selecting one of 3 radio buttons. If the user selects the 3rd button, I want to display an additional field.

Here is the lines of code:

<label>Are you or your spouse a Taft Class of 1965 alumni?</label>
<input type="radio" id="alumni" value=1 checked><label>yes</label>
<input type="radio" id="alumni" value=2><label>no</label>
<br>
<label>Are you a graduate of Taft Union High School?</label>
<input type="radio" id="alumni" value=3><label>yes</label>
      Error  ---> <?php
// If alumni is equal to 3 display the input field
  If ($ans == 3);{
    Echo "<input type='int' id='gradClass' size='4' maxlenght='4' placeholder='1977'>"
  }
?>
    <br>
<hr>
<br>
<span class="subheader">PRIVACY</span>
<br>


And I didn't forget a ' this time.

Could someone please assist. Thanks in advance.
