PHP - How To Check $_post For A String?

Hello guys, I have a form where you can select a score between 0 and 10(only integers). I want to check if the value that I recive, is integer.   Im using this code(exemple):

$integer =  intval($_POST["p1"]);
    if(is_int($integer)){
        echo 'INT';
    } else {
        echo 'NO INT';
    }

My problem is that if it recive letters, the conversion converts it to 0, and it says that it is integer. So with this method I should discard the 0.   You guys know a method to avoid that?   Thank you guys

I have an array of $fl
By using values of this array, i want to create a new string.
I need string size will be maximum 200 characters.
When i try below code snipped, $f value is added to string two times.
How can i add $f to array only one time, with checking size of string.
Thank you

Code: [Select]
$fl=getsomelist(); // gives an array
$userList='';
foreach ($fl as $f) {
    if ( strlen($userList .= $f) <= (200) ) {
        $userList .= $f;
    } else {
        break;
    }
}

I was wondering if anyone knows a good way to check for an even number of each character in a string.  For example if the string is "abbacc" then it will return true as there are two of each character.  However if the string is "ababc" it will return false as there is only 1 c.  Thanks for any help

Hey.

I been using a function to check if a string contains only letters which is:

ctype_alpha

But i would like to change it to allow numbers 0 to 9 and the letters is there a function to do that in PHP i can't find it.

Hi all, i've got a string ($currentcatid) which contains one number which changes dependant on which page the visitor is on.. ie  it may be perhaps "23" or "17" .

I need to do a check against this string to see if it contains any of the following values .. 31,32, 1, 24 . I cant remember how i did it before but i think it was with pipes..

something along the lines of
if ($currentcatid =="31"||"32"||"1"||"24") { action }

can anyone help?

Thanks

I want to check if a string has any of words listed in array;
Code: [Select]
$array=array('word1', 'word2', 'word3');

I have a web server which contains a public site and a private site. I want to be able to test for public or private using the page title and return the appropriate header which contains a different banner, css etc.

Firstly - the syntax below seems to be incorrect because it doesnt work correctly.
More importantly how do I add all the values to an array and than iterate through it to check for a matching page title?

Code: [Select]
public function publicSite() {
if ($this->getTitle()== 'Home' || 'About Us'||'Registration' || 'Sitemap' || 'Contact Us' || 'Useful Links' || 'Feedback') {
return true;
}
return false;
}
Then later on I would have:
Code: [Select]
if ($this->publicSite()) {
require($ROOT.'interface/pages/publicheader.php');
}
else {
require($ROOT.'interface/pages/privateheader.php');
}

Thanks heaps!

Hello Everyone,

I am having issues where people are submitting null characters on my website (I.e. %00).  Currently, I check if their is a value by using the empty function, and I also am checking if the value after running the trim command is =="".  How can I check for these special characters to make sure that whatever they are submitting actually contains some sort of legitimate value?

Thanks!

Hi,

I am trying to make some adjustments to uploadify.php which comes with the latest version of uploadify (3.0 beta), so that it works with a session variable that stores the login username and adds it to the path for uploads.  Here is uploadify.php as it currently looks:

Code: [Select]
<?php
session_name("MyLogin");
session_start();

$targetFolder = '/songs/' . $_SESSION['name']; // Relative to the root

if (!empty($_FILES)) {
$tempFile = $_FILES['Filedata']['tmp_name'];
$targetPath = $_SERVER['DOCUMENT_ROOT'] . $targetFolder;
$targetFile = rtrim($targetPath,'/') .'/'. $_FILES['Filedata']['name'];

// Validate the file type
$fileTypes = array('m4a','mp3','flac','ogg'); // File extensions
$fileParts = pathinfo($_FILES['Filedata']['name']);

if (in_array($fileParts['extension'],$fileTypes)) {
move_uploaded_file($tempFile,$targetFile);
echo '1';
} else {
echo 'Invalid file type.';
}
}

echo $targetFolder;

?>
I added Code: [Select]
echo $targetFolder; at the bottom so that I could make sure that the string returned was correct, and it is, i.e. '/songs/nick'.  For some reason though, uploads are not going to the correct folder, i.e. the username folder, but instead are going to the parent folder 'songs'.  The folder for username exists, with correct permissions, and when I manually enter Code: [Select]
$targetFolder = '/songs/nick';all works fine.  Which strikes me as rather strange.  I have limited experience of using php, but wonder how if the correct string is returned by the session variable, the upload works differently than with the manually entered string.

Any help would be much appreciated.  It's the last issue with a website that was due to go live 2 days ago!

Thanks,

Nick

Hey there,

Thanks for taking the time to read my thread. My issue is that I can't think of a way to edit a XML file using PHP's XML functionality and then assign the edited contents to a string instead of saving the file. Because my issue is that I have to edit the XML file based upon a string brought from a remote location then give it back to that remote location using a string again, to be exact I am doing it via Linux command line utilizing SSH2.

This is what I managed to complete on my own.


function CheckIVMPConfig($ServerID)
{
global $Panel;

if(is_numeric($ServerID) && $this->IsValidServer($ServerID))
{
// We select the game server that the FTP account was created for.
$Servers = mysql_query("SELECT * FROM control_servers WHERE server_id = '".mysql_real_escape_string($FTPAccount['ftp_server'])."'");
$Server = mysql_fetch_array($Servers);

// Here we select the Box ID that the game server is on.
$Boxs = mysql_query("SELECT * FROM control_machines WHERE machine_id = '".$Server['server_machine']."'");
$Box = mysql_fetch_array($Boxs);

// Now we select the required package for the box.
$Packages = mysql_query("SELECT * FROM control_packages WHERE package_id = '".$Server['server_package']."'");
$Package = mysql_fetch_array($Packages);

// Retrive the file.
$Config = $CProtocol->exec("cat /home/{$Server['server_id']}/{$Package['package_config']}");

$Parse = SimpleXMLElement($Config);

foreach($Parse as $Entry) // loop through our books
{
if($Entry->port != $Server['server_port'])
{
// edit the value
}
else if($Entry->maxplayers > $Server['server_slots'])
{
// edit the value
}
}
}
}

Hello all,

I'm trying to change the end of a javascript call based on the end of the url string. The common part of all the url strings is sobi2Id=, I'm trying to do this with strstr but am having no luck. I'm new to php so my syntax knowledge is terrible!

at the moment i've got

Code: [Select]
<?php

       $url = $_SERVER['REQUEST_URI'];

     $tag = strstr ($url, 'sobi2Id=');

       echo $tag; 
?>
but this returns an unexpected T_STRING, expecting ',' or ';'

Can anyone debug this? I may well be being really silly!
