i wanting users to be able to update there email address and check to see if the new email already exists. if the email is the same as current email ignore the check.
i have no errors showing up but if I enter a email already in the db it still accepts the new email instead of bringing the back the error message.
Code: [Select]
// email enterd from form //
$email=$_POST['email'];

$queryuser=mysql_query("SELECT * FROM members WHERE inv='$ivn' ") or die (mysql_error());
while($info = mysql_fetch_array( $queryuser )) {
$check=$info['email'];
// gets current email //
}

if($check!=$email){
// if check not equal to $email check the new email address already exists//
$queryuser=mysql_query("SELECT * FROM members WHERE email='$email' ");
//$result=mysql_query($sql);
$checkuser=mysql_num_rows($queryuser);
if($checkuser != 0)
{
$error= "0";
header('LOCATION:../pages/myprofile.php?id='.$error.'');

}
}

I have a form and script that is used to collect information from users.
There is one field that is url.
There is one field that is email.

I want to filter out scripts. I also only want to allow url in the url field and email in the email field.

Is there an easy way to filter? I have tried several pieces of code to no avail.

Code: [Select]
<?php
$root = $_SERVER['DOCUMENT_ROOT'];
include('/home/arts/public_html/shows/includes/config.db.php');
if ($link)
{
 foreach ($_POST as $k => $v)
 {
 if (($k == "start_date") || ($k == "end_date") || ($k == "application_dead"))
 {
 $varray = explode("/",$v);
 $v = $varray[2] . "-" . $varray[0] . "-" . $varray[1];
 }

 $v = "'" . addslashes($v) . "'";


 if($k != "captcha_code")
{

$keys[] = $k;
$vals[] = $v;
}
 }

 $fields = implode(",", $keys);
 $values = implode(",", $vals);
 //$fields = "id," . $fields;
 //$values = "null," . $values;

 $sql = "INSERT into craft_shows ($fields) VALUES ($values)";

 $result = mysql_query($sql,$link);
if (!$result) {
 die('There was a problem with your submission. Refresh the page to try again');
}
else
{
 echo "Thank you for your submission. ";
 echo "<a href=\"http://www.artsandcraftsnetwork.com/shows/\">Back to shows</a> ";
 echo "<a href=\"http://www.artsandcraftsnetwork.com/shows/shows_submit.php\">Submit another show</a>";

Filtering Arrays Help

Hi guys

I was wondering if anyone could point me in the right direction with this.

I am using JSON to return the contents of a directory and then using a foreach loop to print each one to a new row in a table.

Is there anyway to filter the results? Basically I just want to show the files that end in a .jar extension? Currently all sub directories and files are shown, however all the files I need to pull will be in the main directory.

This is what I am using:

Code: [Select]
<?php
foreach ($installedplugins1['success'] as $v)
{
echo "<tr><td>".$v."</td>";
echo "<td><a href='index.php?dp=".$v."'>Disable Plugin</a></td>";

}
?>

Any hints or reading material?

Cheers

Filtering Gps Points

hi,

i am trying to filter my gps history points.

i would like to ignore points if they are too close to the previous position.

i can do this like so.

$old_lat = $old_long = "0";

foreach($history['data'] as $record) {

//calculate distance in meters
$distance = distance($record['latitude'], $record['longitude'], $old_lat, $old_long, "V");

if($distance >= 300) {
echo 'add(jQuery(this), number += 1, "' . date("d-m-Y @ h:i:s",$record['timestamp']) . '", "map_post.php?n=' . $name . 'u=' . $history['user'] . '", "' . $history['user'] . '", "' . $record['latitude'] . '", "' . $record['longitude'] . '");';

$old_lat = $record['latitude'];
$old_long = $record['longitude'];
}

the problem with the above is that if i arrive home at 6pm on friday and stay outside my house for 24hours, it will show the latest position as at 6pm on fri.

i would like it to show the 6pm friday position but with a date 'from and to' time like (28/10/11 18:00 - 29/10/11 18:00) rarther than just (28/10/11 18:00) which looks inacurate.

Possible?

Utf-8 Filtering/validation

Similar Tutorials

View Content

First off, i have made a validation class using array_diff() to check if there are invalid characters submitted by a user.
Some extracts:
Code: [Select]
$this->chr_alpha_lower=array('a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z');
$this->chr_alpha_upper=array('A','B','C','D','E','F','G','H','I','J','K','L','M','N','O','P','Q','R','S','T','U','V','W','X','Y','Z');
$this->chr_numeric=array('0','1','2','3','4','5','6','7','8','9');
$this->chr_symbol=array(' ','!','@','#','$','%','&','(',')','[',']','.',',',':',';','\'','"','/','=','\\','-','_','?');

...

// lets say only alpha and numeric characters are allowed
$allowed_characters=array();
$allowed_characters=array_merge($allowed_characters,$this->chr_alpha_lower,$this->chr_alpha_upper);
$allowed_characters=array_merge($allowed_characters,$this->chr_numeric);

$input_split=str_split($this->input);
$invalid=array_diff($input_split,$allowed_characters);

if(empty($invalid)){
return true;
}
return false;

I have two questions.
First, for acsii characters is this method 'full proof' or is there a way for someone to get around this validation script?

Second, a new site im developing is going to be built with UTF-8 in mind so people can use the site in their own language. How do i validate UTF-8 user input? I know about mb_strings and sanitizing UTF-8 input using this:
Code: [Select]
preg_match_all('/([\x09\x0a\x0d\x20-\x7e]'. // ASCII characters
'|[\xc2-\xdf][\x80-\xbf]'. // 2-byte (except overly longs)
'|\xe0[\xa0-\xbf][\x80-\xbf]'. // 3 byte (except overly longs)
'|[\xe1-\xec\xee\xef][\x80-\xbf]{2}'. // 3 byte (except overly longs)
'|\xed[\x80-\x9f][\x80-\xbf])+/', // 3 byte (except UTF-16 surrogates)
$input, $clean_pieces );

$clean_output = join('?', $clean_pieces[0] );

But how do i know what to filter?

Example:
a field for the user to input first name
English: only alpha characters
Other language: ?????

Help much appreciated.

How Good Or Bad Is The Sql Filtering?

I have a SQL statement which is difficult to use PDO on, it might not even be possible to do. So I'm filtering it like this:

$search = $_GET['search'];
$search = preg_replace("/[^A-Za-z0-9]/", " ", $search);
$search = $mysqli->real_escape_string($search);

Will this result in an acceptable level of security?

Hi all,

I am working on a tool to pull data remotely and the data is set to xml format. I want to post items that meet a certain criteria only, essentially there are several layers/tags on the data being brought over. The sStatus is the primary item I am looking for, not only that but only if it has or equals to "Waiting". Any thoughts or suggestions greatly appreciated. Below is the basic code I have in place currently and am working on.

<code>
<?php
$soapclient = new SoapClient("https://secure.logmeinrescue.com/api/api.asmx?wsdl");

$sEmail = "dummy@dum.com";
$sPassword = "dum123";
$iNodeID = "123456";
$eNodeRef = "NODE";
$sAuthCode = "";

$loginparams = array (
'sEmail' => $sEmail,
'sPassword' => $sPassword);

$loginResult = $soapclient->login($loginparams);

$output = array(
'eOutput' => "XML"
);

$outputResponse = $soapclient->setOutput($output);

$sessionparams = array(
'iNodeID' => $iNodeID,
'eNodeRef' => $eNodeRef,
'sAuthCode' => $sAuthCode
);

//get session(s)
$sessionresult = $soapclient->getSession($sessionparams);
$session = $sessionresult->aSessions;
$sessionnodes = $session->SESSION;
$session_status = $sessionnodes[$isessionNodes]->sStatus;

print_r($sessionresult);

Not Filtering Words?

I'm pretty sure the problem is starring me in the face, but I can't seem to locate it.

function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);

foreach($bad_words as $value)
{
$string = str_replace($value, '****', $input);
}

return $string;
}

UPDATED CODE

function filter($string)
{
//swear words pulled from bannedwordlist.com
$f = fopen('../badwords.txt', 'r');
$bad_words = fread($f, filesize('../badwords.txt'));
$bad_words = explode('\n', $bad_words);

$input = strtolower($string);
$string = str_replace($bad_words, '****', $input);

return $string;
}

I've already echoed out $value in the foreeach loop, and it does correctly retrieve the bad words and put them into an array. My only problem is, the returned string is still in strtolower() form, and the words aren't censored. :/

Mysql Search With Filtering, Please Help!

Hi Everybody,

I think it's fairly simple, but i am a noob in PHP so need help from advanced coders.

I have MySQL table which is being filled up everyday, there are 7 fields in the table (submitter, choosebank, choosetype, ampaid, amret, date, descript).
What I need is to create a search.php which will be looking up data in all fields and printing it on the screen and the search should be filtered. What I mean is when a user wants to search for data let's say using submitter who's name is Mitchel then it should search for all data and print all rows containing submitter (Mitchel) and the rest six fields. And if user searches let's say using submitter (Mitchel) and a certain date (let's say DEC-25-2011) then it should find all data containing Mitchel and DEC-25-2011 in the same row and print all rows which contain the same search parameter and the rest of the fields.

Any help would be greatly appreciated!

Here is the code I have so far, but it doesn't work.

<code>

<?php

include ("blocks/db.php");

$sql = mysql_query("SELECT * FROM banks WHERE submitter LIKE '$sub' or choosebank LIKE '$bank' or choosetype LIKE '$type' or $money_column LIKE '$money_column' or $money_value LIKE '$money_amount' or inputdate LIKE '$inputdate' or descript LIKE '$descript'") or die(mysql_error());

echo "<table width='1000' border='1' cellspacing='0' cellpadding='1'>";
echo "<tr>";
echo "<td width='100'>Submitter</td>";
echo "<td width='90'>Bank</td>";
echo "<td width='110'>Type of Payment</td>";
echo "<td width='110'>Amount Paid</td>";
echo "<td width='110'>Amount Returned</td>";
echo "<td width='100'>Date</td>";
echo "<td width='366'>Description</td>";
echo "</tr>";
echo "</table>";

while ($row = mysql_fetch_array($sql)){

echo "<table width='1000' border='1' cellspacing='0' cellpadding='1'>";
echo "<tr>";
echo "<td width='100'>$row[submitter]</td>";
echo "<td width='90'>$row[choosebank]</td>";

I then want to be able to filter out duplicate permutations. i.e. 1,2,3 is the same as 1,3,2.

I have googled vigorously but not been able to determine a suitable approach.

Filtering Inner Join Data

Similar Tutorials

I'm using an INNER JOIN to grab some data from 2 tables depending on if another's id matches an id within the other table (obviously.. ).

Is there anyway to continue on with this join but to filter even deeper by only taking data that not only has matching some_id but also does not have a row that equals a certain value?

Something along the lines of adding "WHERE some_row != 'value'" ?

"SELECT * FROM my_firstTable INNER JOIN my_secondTable ON my_firstTable.some_id = my_secondTable.some_id ORDER BY my_firstTable.some_id"

Filtering A Street Address

Hey guys, we have a website where people are able to post things, and we don't want to allow anyone to be able to post their street address, for obvious reasons. I'm really stuck on this one, I've looked for some regular expressions to no avail...one idea we did have was to check a text for an address then check to see if it was a valid address with the google maps API but then again...it goes back to having a regular expression for capturing the street address. I was wanting to know, is there any way I will be able to catch whether a user has posted an address? I was going to post this in the regex section but I'm not sure if I should use any regex's or if there might be another way.

Put basically I need to be able to strip a street address from the text if a user posts one.

I'm pretty sure it's probably not possible, but I figured I'd ask first. Thanks for any help anyone can provide!
