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.

How can I check if a function has returned false.. I know theirs the following way:

if (!checkdate($month, $day, $year)) {
//the function has returned false
}

But is their another way (beside using the ! operator) perhaps === FALSE (not sure if that'd work so asking)?

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");
		}

 

 

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!

I am trying to do a loop which uses file_exists to check if an image exists and if so display it using the following code:

<?php
$i = 1;
while ($i <= 8) {

$filename = $img_loc . "/hovers-800px/" . $image . "-" . $i . ".jpg";

if (file_exists($filename)) {
?>
<a class="fuglybox" rel="gxr" href="<?php echo $filename; ?>"> <!--Main thumbnail image-->
      <img src="<?php echo $img_loc; ?>/product-detail-90px/<?php $image . "-" . $i . ".jpg"; ?>" alt="" width="90" height="90" /></a>
<?php

}

$i++;

}

?>

I have echoed out $filename to check my directory structure and filename is fine and copied the echoed directory out. The structure is however http://Http://www.xxxxxx.com/img/filename.jpg. Could this be whats causing the problem?

I've read as many previous posts as I can find and tried all the suggested solutions but the following simple test code will not work for me (the session variable has been echoed and is correct).   Instead of echoing the correct answer, the if(file_exists($target_file)) skips the true result and always displays the false one.  I've tested it with files that do and don't exist of course.  Here is the code :-

$filename = $_SESSION["filename"];
$target_file = $_SERVER['CONTEXT_DOCUMENT_ROOT'] . '/folder/' . $_SESSION["filename"];

if (file_exists($target_file)) {
    echo 'Selected file is ' . $filename . ' and will be written.';
} else {
    echo "Selected file " . $filename . " doesn't exist.";
} 

I'd really appreciate any help on this please.

<code>
$jpg_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.jpg';
$jpeg_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.jpeg';
$gif_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.gif';
$png_path = '../../../users/user_avatars/' . $_SESSION['the_user'] . '.png';
$jpg_test = file_exists($jpg_path);
$jpeg_test = file_exists($jpeg_path);
$gif_test = file_exists($gif_path);
$png_test = file_exists($png_path);
</code>

the path is EXACTLY correct I've checked and rechecked and everything. echoed the path and everything else that is relevant. but later when I call if ($png_test == '1') {
blah blah blah
}
it won't return 1. even though I KNOW that the picture is there and it is at that path. if i echo the path in a src for an image it appears. hmm?

Hello all,

I am a real newby to this but need some help with a file_exists / while loop issue i have.

I am trying to show a table of pictures (with their own ID's) but also if someone hasn't uploaded a picture to the server a default picture will be shown instead.

I get the error: Parse error: syntax error, unexpected T_VARIABLE, expecting ',' or ';' in /home/thefrien/public_html/members1.php on line 103

Here is my code:

$i = 1;
echo "<table border='1' align='center'><tr>";
$result = mysql_query( "SELECT * FROM membership order by L_ID asc" );
while ( $row = mysql_fetch_assoc( $result ) ) {
    echo "<td align='center' bgcolor='#DDDEFF'><a href='profile_view.php?L_ID=".$row["L_ID"] ."'>"
   $pic = 'images/avatar/'. $row["L_ID"] .'s.jpg';   
if (file_exists($pic)) {
   echo '<img src=http://www.thefriendzconnection.co.uk/images/avatar/'.$row["L_ID"] ."s.jpg>";
} else {
   echo '<img src=http://www.thefriendzconnection.co.uk/images/0s.jpg border='0'>';
}
   "</a>
   <br><font size='1' face='Arial, Helvetica, sans-serif'>".$row["name"] ."</font>
   <br><font size='1' face='Arial, Helvetica, sans-serif'>ID: ".$row["L_ID"] ."</font>
   <br>&nbsp;</td>";
    if ( $i % 6 == 0 ) { echo "</tr><tr>"; }
    $i++;
}
mysql_free_result( $result );
echo "</tr></table>";



The line I am having issues with seems to be: $pic = 'images/avatar/'. $row["L_ID"] .'s.jpg';

Any suggestions would be greatfully received

Thanks.

I'm just trying to find out if php has the ability to check if any file exists, with only part of the filename given..

I have this path:

if (file_exists($dir.'/'.$c_file.'/templ_*')) {

I added a little star.. That star represents whatever the rest of that file is named for this example.. It could be anything.. So can php match any files that start with "templ_", and say that it does or does not exist??

Thanks

I want to get suggested keywords from yahoo api service. When xml file is empty (no keyword), it gives error. To resolve this problem I used this code:
if (file_exists('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2')) {
$xmlmetades = simplexml_load_file('http://search.yahooapis.com/WebSearchService/V1/relatedSuggestion?appid=YahooDemo&query=Madonna&results=2');
}


Since it is not a normal .xml file, it is always considered no file, and return nothing.

My setup: (everything on a local network)
Web server: Ubuntu Server 8.10 -- Workgroup
File server: Windows Server 2008 x64 -- domain
Test server: Win 2000 running WAMP -- domain

I'm trying to run the code snippet below. $file is a file on the File server above. It definitely exists.
Running the code below on the Test server works perfectly. But the file cannot be found when running from the Web server.
$file = '//server/share/file.txt';
if (file_exists($file))
echo 'yay!';
else
echo 'error';

What with the safe mode considerations, I've also tried to add:
ini_set('safe_mode', 'Off'); to no effect. And since file, and fopen similarly not work, I'm pretty sure it's not that either.

The File & Test servers are on the same Windows domain, but that's definitely not the reason. I tried the code on a file on a Linux computer in the Workgroup (where the Web server is) with the same results: Test server works, Web server does not.

Please advise; I'm really lost.
