PHP - Foreach - Invalid Arguement

Hi , can somebody help me with this warning? Warning: Invalid argument supplied for foreach() in /home/wwwdesig/public_html/mailer.php on line 12 It´s just a simple php mailer Here is the php code:       <?php if(isset($_POST['submit'])) {

I am a total newbie at PHP and I have a wordpress plugin that works well but sometimes does not return any results to the query which I believe is causing this error:

Warning: Invalid argument supplied for foreach() social-media-integrated-related-content-smirc/lib/smirclib.php on line 182

From what I am reading on other forums the problem is possibly that the foreach loop is empty since the array must have elements. The solution being  to add a check above the foreach loop, to count the number of elements in the array, and if it is zero, skip the foreach loop. Is this correct? Here is the code....can someone please edit it so I can see an example of how it should be done? Again total PHP newbie so please be clear if possible. Thanks so much!!!

I have a weird problem with an md5() function.

I am trying to write a token system, (just for my own fun really), going off an example guestbook I got help with from here.

What my main aim is to allow the moderator for the guestbook to receive an email (which is working in its own context), with a link to a script page that checks into the database and when the user clicks on the link it allows the message in the guestbook to be shown.

But when I try md5() the ip address of the user it works, but I thought if that same user went in and did another post, it would come up with the same checksum, causing quite bad problems to be honest.

So I thought about using something like:


$time = microtime();
$checksum = md5($ip,$time);


But this keeps coming up with say:

Is there anyway of getting around this at all?

To show a real value as I am sure this wont work, any helps greatly appreciated,

How can I prevent someone from making an ivalid selection in a form? Lets say I had a select dropdown box and someone saved the HTML source from the browser, changed an item in the list, and changed the action to point back to my server eg. action="testsite.com/index.php". Then they open the file and try to submit the form.

Hi

I have a couple of phpbb forums on my web space.

One is randomly throwing people off and it is getting far worse.

I have traced down the issue to the IP address. Phpbb stores the IP address and session id and checks that they match. If not it throws the user out. The session ids seem to be there OK, but the IP addresses aren't.

When it causes a problem the IP address seems to be returned as "::" (yes, 2 colons).

I have used the following routine to try and obtain a relevant IP address and it to returns "::"

Code: [Select]
function getRealIpAddr()
{
    if (!empty($_SERVER['HTTP_CLIENT_IP']))   //check ip from share internet
    {
      $ip=$_SERVER['HTTP_CLIENT_IP'];
    }
    elseif (!empty($_SERVER['HTTP_X_FORWARDED_FOR']))   //to check ip is pass from proxy
    {
      $ip=$_SERVER['HTTP_X_FORWARDED_FOR'];
    }
    else
    {
      $ip=$_SERVER['REMOTE_ADDR'];
    }
    return $ip;
}

Any ideas?

All the best

Dont understand why...my database is displayed correctly but cant seem to add edit delete etc, I just get the error above.   Any clues please

I have a class (P3TElement) that extends the DOMElement class in PHP. In there i have a public variable "attributes" which is an array, and an method named add_attribute($attr), the argument is a different class (P3TAttribute). However I am getting an error when trying to use it.
The exact error is:
Warning: P3TElement::add_attribute() [p3telement.add-attribute]: Invalid State Error in D:\www\p3textract\extract.php on line 110

Please see the code: http://pastebin.com/CbsM9V5W

This class is supposed to extract .p3t (ps3 themes) files, and is a direct port of the python equivalent found at http://p3textractor.googlecode.com/svn/trunk/p3textractor.py

Could you please help me fix this?

thanks in advance,

Hi,

I've inherited some html/php code (lucky me) and it's been years since i've played with it so I'm quite rusty.

Anyway, I have a fairly bog standard login process and wish to simply display some text on the login page if the login detail is invalid and possibly
log the error to a log file too.

here's the index.php file...the login stuff is at the bottom

Code: [Select]

<?php 
$dir = dirname(__FILE__);

require_once "$dir/ot/ot.php";

ot::include_view('header', array('account' => null))
?>

<html>
<head>
<title>Welcome to ....</title>
</head>

<body style="font-size: 14pt; font-family=verdana;">
<div><img src="OTLogo1.bmp"/><h1> Welcome to ...</h1> </div>
<?php if (!empty($account)): ?>
    <div style="border-bottom: 1px dotted #AAA; padding-bottom: 2px; margin-bottom: 10px;">
        <div style="float: left">
            <?php
                $mtime = (int)@file_get_contents(otDB_DIR."/updated");
                $date = date("d/m/Y", $mtime);
                $time = date("G:i", $mtime);
                if ($mtime > 0) {
                    echo "Last Updated $date at $time";
                }
            ?>
        </div>
    <div style="float: right">Welcome, <?php echo $account->email;?> - <a href="?page=home">Home</a> - <?php ot::include_view('logout_link')?></div>
        <div style="clear: both"></div>
    </div>
        <?php
            if (ot::is_admin()) {
                ot::include_view('admin_page');
            } else {
                ot::include_view('user_page');
            }
        ?>
<?php else: ?>
    <p>Please login below.</p>
<?php ot::include_view('login_form')?>
<?php endif; ?>

</body>
</html>
here's login_form.php

Code: [Select]
<form action='<?php echo $_SERVER['REQUEST_URI']?>' method='post' >
<fieldset>
<legend>Login</legend>
<p>Email:<br/><input type='text' name='email' /></p>
<p>Password:<br/><input type='password' name='pwd' /></p>
<!-- <p><input type='submit' name='do_login' value='Login' /> <input type='submit' name='do_reset_password' value='Reset Password' /></p> -->
<p><input type='submit' name='do_login' value='Login'/> </p>
</fieldset>
</form>

and here's the function do_login (contained in ot.php..a php function file)

Code: [Select]

public static function do_login(&$err="")
{
$adb = ot::db('account');
$e = self::post('email');
$p = self::post('pwd', '', false);
if (self::post('do_login') && $e && $p) {
$ao = self::account_from('email', $e);
if ($ao) {
if (self::validate_login($e, $p, $ao)) {
$_SESSION['id'] = $ao->id;
return $ao;
}
}
$err = "Invalid email or password";
return false;
}
}
I'm unclear if the do_login fails as to how that ($err) is fed back to the web pages.

Any assistance would be greatly appreciated.

I want to allow Alphabetical strings, Numeric strings, and Alphanumeric strings. For example "Bob", "1234", "bob1234" are all valid.

I want to check if the string has invalid characters, return true if it does (or false, which ever method works).

How can I do it?
