PHP - Read_file() Returns False For No Reason

Hi, I'm pretty new to PHP and I am working on a form that sends and email. I want to display a message if the mail can't be sent (i.e. if mail() returns false) and a different message if mail() returns true, except it is returning false even though the emails are sending.


Basically I have used:

$to = 'myemail@email.com';
$subject = "Subject Line Goes here";
$headers = "From: $email";
$message = 'My message';

$mailSent = mail($to, $subject, $message, $headers);

In testing it I have used the following to determine what is going on:

   if (isset($mailSent)) { echo '$mailSent ='.$mailSent; } - echo's nothing
   if ($mailSent == FALSE) { echo '$mailSent = FALSE'; } - echo's '$mailSent = FALSE'
   if ($mailSent == TRUE) { echo '$mailSent = TRUE'; } - echo's nothing
   if (is_null($mailSent)) { echo '$mailSent = NULL'; } - echo's '$mailSent = NULL'
   echo '$mailSent ='.$mailSent; - echo's '$mailSent ='

Any help would be greatly appreciated!
Thanks!

I'm working on a WordPress theme and I'm trying to build in a simple if statement which will check if the user has add his own logo into the images folder if he doesn't then the name of the blog will appear as normal text in place of the graphic logo.

This is how it looks like:


<?php

$logo_dir = get_template_directory_uri() . "/images/logo.png";

if (file_exists($logo_dir)) { ?>

<li><img src="<?php bloginfo ('template_directory'); ?>/images/logo.png" alt="<?php bloginfo('description'); ?>" /></li>

<?php } else { ?>

<li id='blog_name'><a href="<?php bloginfo('url'); ?>"><?php bloginfo('name'); ?><font>*</font></a></li>

<?php } ?>




I've echo'd out $logo_dir, the URL is correct, but still for some reason it's seeing it as if there would no file exist. If I turn it around into !file_exists then the graphic logo WILL show up. So it's always seeing it as non-existent.

Any ideas why this could be or am I using this function in a wrong fashion? As far as I've understood the PHP manual, this is the correct way of using it.

I tried parsing through first

https://www.jadaliyya.com/Details/28167/The-Empire-of-Sexuality-An-Interview-with-Joseph-Massad

then even tried

www.google.com

and on both I get the following returned

 

post_url equals:
www.google.compost_title equals:
testpost_Threadybody equals:
Enter your posts...

URL equals: www.google.com

www.google.com is not a valid URL

Web page redirects after 2 seconds.

And here is the if statement that handles my filter for URLs

if(isset($_POST["submit"]) && !empty($_POST["url"]) && !empty($_POST["Title"])){
$URL = $conn -> real_escape_string($_POST["url"]) ;
$BodyText = $conn -> real_escape_string(nl2br($_POST["ThreadBody"])) ;
echo "<P>URL equals: " ; 
echo $URL ; 
echo "<P>" ; 
//Change to embed for youtube.


if (filter_var($URL, FILTER_VALIDATE_URL)) {
    echo("$URL is a valid URL");
	//Check if url is a youtube url 
	if (strpos($URL,'youtube') !== false) {
	    echo 'Youtube exists.';
	  $URL = preg_replace("/\s*[a-zA-Z\/\/:\.]*youtube.com\/watch\?v=([a-zA-Z0-9\-_]+)([a-zA-Z0-9\/\*\-\_\?\&\;\%\=\.]*)/i","<iframe width=\"420\" height=\"315\" src=\"//www.youtube.com/embed/$1\" frameborder=\"0\" allowfullscreen></iframe>",$URL);

	} else {
	    echo 'Youtube is not included .';
	   $URL = "<ahref ='" . $URL . "</a>" ;  
	}


	$Title = $conn -> real_escape_string($_POST["Title"]) ;
	$User = $_SESSION['username'];
	 
	 
	 $sql = "INSERT INTO Threads (Title, Users, ThreadBody, url)
     VALUES ('$Title', '$User','$BodyText','$URL')";
     if (mysqli_query($conn, $sql)) {
        echo "New record has been added successfully !";
     } else {
        echo "Error: " . $sql . ":-" . mysqli_error($conn);
     }

		} 
else {
    echo("$URL is not a valid URL");
		}

Here is the form:

Code: [Select]
<?php
include_once('../../header.php');
include_once('../../model/contribution/create_new_tag_script.php');
?>

<form action="" method="post">
    <input type="text" name="tag_name" value="" />
    <textarea maxlength="60" type="text"  name="tag_description" value=""></textarea>
    <input type="submit" name="tag_name_submit" value="Submit the New Tag" />
</form>


<?php
include_once('../../footer.php');
?>
By the script as given above the conditional check will skip to the error message.

Though I have to say that ctype_alpha does return TRUE when I do try it with "tag_name" which is entered data from the input field, while the other is from the textarea.

I simply cannot see the reason for the returned FALSE.

Hello , this is my first post in this forum , i would like to see the following code and tell me your opinion , not about the security issues not about how good or bad it is. Its just a simple demonstration in order to show you the problem.

<?php

include('config/functions.php');

$mysqli = connectionToDb();

$mysqli->autocommit(FALSE);

$stmt = $mysqli->prepare("INSERT INTO users (first_name,last_name) VALUES ('stelios','stelios2')");
$stmt->execute();
$stmt->close();

$stmt = $mysqli->prepare("INSERT INTO users (first_name,last_name) VALUES ('stelios3','stelios4')");
$stmt->execute();
$stmt->close();

var_dump($mysqli->commit());

$mysqli->close();

This is the code and the var_dump($mysqli->commit()); line prints false ! BUT , the inserts are in the database. If i comment out the commit line , then nothing is in the database.    Can you advise ? Thanks !

in my code below the **data is extracted correctly for the first foreach but doesn't return anything for 2nd foreach though selected one present inside the 2nd foreach** i still get the error Warning: Invalid argument supplied for foreach() for line `foreach ($authorlist as $post)`... however the 2nd foreach returns data correctly as soon as i remove the first foreach loop. 

hi there,

is there a difference between if($var == false) and if(false == $var)

thankyou!

for the below code, what does the get_magic_quotes_gpc part mean?... in simple terms

Code: [Select]
$photoname = $_FILES['photo']['name'];

if(!get_magic_quotes_gpc())
{
    $photoname = addslashes($photoname);
}

Hey


I have a script that builds an array but for some reason there is a loose integer in the variable which is confusing me and i think its the cause of my syntax errors in javascript. But i got no idea where it is coming from =/


Here is the function i use:

Code: [Select]
<?php
function img($id) {
      $img = array();
      $img['tiles'] = $this->db->getAll("SELECT DISTINCT t.id, CONCAT('data/tiles/',filename) AS f FROM `map_tiles` AS mt
               INNER JOIN `tiles` AS t ON (mt.tile=t.id)
                WHERE mt.map_id={$this->db->qstr($id)}");

      echo print_r($img); 
      die;            
      //exit(json_encode($img)); // turned off for testing
?>


The echo returns this:
Code: [Select]

Array
(
    [tiles] => Array
        (
            [0] => Array
                (
                    [id] => 10
                    [f] => data/tiles/floor.png
                )


        )

)
1  <----- why does this appear? And could this cause a syntax error if sent back for JS processing?


As you can see there is 1 showing at the end but i don't see why =/ Any ideas if thats suppose to happen ?

I normally don't have a problem with concenation, but for some reason I can't get it work in this case.

I have two form variables: firstname_ord and lastname_ord.
I have tried concenating them several ways, and get nothing afterwards.

attempt 1:
$lastname = "firstname_ord" . " " . "lastname_ord";

attempt 2:
$firstname = "firstname_ord";
$lastname = "lastname_ord";
$fullname = $firstname . " " . $lastname;

attempt 3:
$fullname = "firstname_ord";
$fullname = $fullname. " " . "lastname_ord";

attempt 4:
$fullname = "firstname_ord";
$fullname .="lastname_ord";

attempt 5:

$fullname = (string)"firstname_ord";
$fullname .= " ";
$fullname .=(string)"lastname_ord";

I have this code below in a while loop, that gets looped through about 10 times and is simply resizing a slightly larger image to fit within a 50px max square. There is other code on my page, but I've narrowed the slowness down to this specific bit of code (i.e. if I take this snippet out, the page loads instantly).  With this snippet, the page takes between 5 and 10 seconds to load, which seems absurd for 10 images.  FYI, the original images are no larger than 200 px on either side, so it's not like it's looping through large image files. 

Anyone know why this might be taking so long?  Should I be doing it differently somehow?

Code: [Select]

list($width,$height) = getimagesize($myimage);
if ($width > $height) {
$datasofar .= "width=50 /></span>";
} elseif ($height > $width) {
$datasofar .= "height=50 /></span>";
} else { //height and width must be equal so just set width = 50, but could just as easily set height to 50
$datasofar .= "width=50 /></span>";
}

Here are the two if statements:

   if (!($start <= 0)){
   
   $prev_button = "<a href='forum.php?category_id=$category_id&start=$prev'>Prev</a>";
   
   }
   
   if (!($start >= $record_num - $per_page)){
   
   $next_button = "<a href='forum.php?category_id=$category_id&start=$next'>Next</a>";
   
   }

But they are not properly working. This is part of a pagination script for the next and previous buttons.

I've noticed some people don't use { } when they right statements, when I first started learning PHP a couple years ago, I thought you HAD to put the curly brackets, but apparently not, how does this work and why don't some people use them in their scripts?

Used to be a good option, but don't know anymore as password_hash() is now available.   Agree?   I understand that I shouldn't ever manually salt and disable the functions salting.  That being said, is there any reason to add a bit extra to the user's password (such as an internal ID and some random constant)?

I spent the last hour or so typing this code up, and for some reason I am getting a query error. I have reviewed & revised the code up and down for the past half hour and can't seem to figure out the problem.

Can someone look after this for me and tell me what I could be doing wrong?

Yes, I know my code is a bit sloppy and may use bad practice techniques, but it works for me.

Its a survey that I coded so I could collect data and place it on CPA ad listings. So I need this so work at some point soon.

My code:
<?php
$user = $_POST['user'];
$email = $_POST['email'];
$password = $_POST['pass'];
$paypal = $_POST['paypal'];
$q1 = $_POST['q1[favsite]'];
$q2 = $_POST['q2[isp]'];
$q21 = $_POST['q2.1[bill]'];
$email_services = $_POST['email_services'];
$ebay = $_POST['ebay'];
$amazon = $_POST['amazon'];
$q6 = $_POST['q6[purchase]'];
$q7 = $_POST['q7[social]'];
$q8 = $_POST['q8[bookmarks]'];
$q9 = $_POST['q9[search]'];
$q10 = $_POST['q10[homepage]'];
$q11 = $_POST['q11[5topsites]'];
$q12 = $_POST['q12[state]'];

if ($_POST['fin'] == "complete") 
{
  
     $dbc = mysqli_connect('localhost', 'root', 'password', 'database')
     or die('Could not connect');
     $query = "INSERT INTO user_data (id, user, email, password, paypal, q1[favsite], q2[isp], q21[bill], email_services, ebay, amazon, q6[purchase], q7[social], q8[bookmarks],             q9[search], q10[homepage], q11[5topsites], q12[state]) VALUES ('$user', '$email', '$password', '$paypal', '$q1', '$q2', '$q21', '$email_services', '$ebay', '$amazon', '$q6', '$q7', '$q8', '$q9', '$q10', '$q11', '$q12')";       
     
      mysqli_query($dbc,$query)
      or die('Error querying database');
      
    include_once("../phpmailer/class.phpmailer.php");
$mail = new PHPMailer;
$mail->ClearAddresses();
$mail->AddAddress('', '');
$mail->From = '';
$mail->FromName = '';
$mail->Subject = 'Thanks for finishing the survey!';
$mail->Body = "Hello, $user. This is a reminder that you have finished the survey and your credit is currently 
being processed. Please login to your account at ../../ to view the status of your credit & cash out.
";
if ($mail->Send()) {
    echo "<center>Mail Sent.</center>";
} else {
    echo $mail->ErrorInfo;
}
echo "<center><h2>Thanks for completing the survey! Please <a href='login.php'>login</a> to your account to view the status of your credit & cash out.</h2></center>";
}
?>

It has nothing to do with PHPMailer, I of course edited the variables just now so all my info wouldnt be public, but everything is fine untill you press submit & I get the or die() error message "Error querying database".

What the hell did I do wrong? Is it possible that I cant name variables in the format I used with most of them ($var1 = $_POST['var[desc]']; ?
