PHP - Length Parameter Must Be Greater Than 0...?
$file = 'includes/views.txt'; $f = fopen($file, 'w+'); $views = fread($f, filesize($file)); fwrite($f, $views+1); fclose($f); The contents of views.txt is: Code: [Select] 1 Why is it returning it needs to be greater than 0?...The file isn't empty. Similar TutorialsI have the following code just to insert a username and hashed password into the database but somehow I am getting this error and I couldn't find out where I am doing it wrong...can someone please give me a hand?
I tried it in two ways and both errors...
the first few lines are just connecting database which worked fine and a password.php so I can use password_hash() with my php version
$hash = password_hash('xx', PASSWORD_BCRYPT, array('cost' => 10));
$username = 'xx';
$insertQuery = $db->prepare("
INSERT INTO et_todo (username, password)
VALUES (:username, :hash)
");
$insertQuery->execute(array(
'username' => $username,
'password' => $hash
));
also tried
$hash = password_hash('xx', PASSWORD_BCRYPT, array('cost' => 10));
$insertQuery = $db->prepare("
INSERT INTO et_todo (username, password)
VALUES ('xx', :hash)
");
$insertQuery->execute(array(
'username' => 'xx',
'password' => $hash
));
Hello,
I recently posted here about an issue I was having with my database orientated products page.
I have now run into another problem where say if, /db.php was typed or /db.php?p=IDoNotExist was typed, it returns blank.
I have in my code the desired content to be displayed, but it just doesn't seem to want to make a show.
I was also wondering if it is possible to show different content for whatever the URL is, so for no parameter, the content about the products, and a non existent one, maybe "Product not found"?
Here is my code:
<?php
$db=mysql_connect ("localhost", "webwibco_charlie", "Hello123") or die ('I cannot connect to the database because: ' . mysql_error());
$mydb=mysql_select_db("webwibco_products");
include("header.php");
$status = htmlspecialchars( @$_GET ['p'] );
if ($status == "floorpuzzles") {
echo "<h1>Our Floor Puzzles</h1>";
$sql="SELECT ID, Name, Tags, Description, Category FROM products WHERE Category LIKE '%" . FloorPuzzles . "%'";
$result=mysql_query($sql);
while($row=mysql_fetch_array($result)){
$Name =$row['Name'];
$ID =$row['ID'];
$Description =$row['Description'];
echo "<div class=\"box\">";
echo "<h1>$Name</h1>";
echo "<div class=\"floorbox\"><a href=\"?p=$ID\"><img src=\"images/products/catalogue/big/floorpuzzles/$ID.jpg\" class=\"small\"></a></div>";
echo "<h2>$Description</h2>";
echo "</div>";
}
?>
<?
}else{
if ($status == $_GET["p"]) {
$sql="SELECT ID, Name, Tags, Description, Pieces, Size, Barcode, Category FROM products WHERE ID = '" . $_GET['p'] . "'";
$result=mysql_query($sql);
while($row=mysql_fetch_array($result)){
$Name =$row['Name'];
$ID =$row['ID'];
$Description =$row['Description'];
$Pieces =$row['Pieces'];
$Size =$row['Size'];
$Barcode =$row['Barcode'];
echo "<div class=\"1\">";
echo "<h1>$Name</h1>";
echo "<div class=\"bigbox\">";
echo "<div class=\"floorbox\"><img src=\"images/products/catalogue/big/floorpuzzles/$ID.jpg\" class=\"big\"></div>";
echo "</div>";
echo "</div>";
echo "<div class=\"2\">";
echo "<p>Puzzle Pieces: $Pieces</p>
<p>Puzzle Size: $Size</p>
<p>Barcode: $Barcode</p>";
echo "</div>";
}
}else{
?>
<?
echo"<h1>Our Products</h1>
<p>Our jigsaw puzzles are hand cut by skilled craftsmen and therefore each one is unique with self-correcting pieces. There is a strict quality control process at all stages by our highly experienced staff. The puzzles are durable and provide fun and excitement, enhancing learning and a child’s development.<p>

<p>Reducing waste and recycling was a way of life for us before it became fashionable. We are constantly searching for new ideas and consult teachers when developing our jigsaws, which are often used within the national curriculum.</p>
<p>As well as making our own range, we manufacture for leading suppliers to the education market. Check for \"Made in Britain\" and it is probably made by us.</p>
<p>We have a wide variety of products available for viewing, from classic floor puzzles to innovative inset trays. You can take a look at all our products on this page, simply use the navigation buttons to your left.</p>";
}}
include("footer.php");
?>
The final echo is what I wish to be displayed on the URL without or with an invalid parameter.
Here is my site URL: http://www.webwib.co...saws/search.php (note that only the "Floor Puzzles" category has content within it).
Thank you in advance for assistance.
I know the default length of a tiny int is less than an int, but if I put in the same length for both, are they essentially the same type? hello, how would i write if $dollars is greater than 5 or less than -5? thanks! how do I write a statement using a greater than and less than Code: [Select] if($soandso >=4 && <=6) {}how would I do something like this? Hi, My example: $setting = 4 //can challenge if opponent has 4 points lesser than you $team1 = 13; //challenger points $team2 = 7; //points In my above case, it should return false because 13-7 = 6, $team2 has 6 points lesser than team 1. If team2 had 4 points or lesser, it should return true. Can someone write the if() statement for me please? Appreciate that alot. Thanks Hi im pritty new to PHP used to using ASP but found PHP to be more resourcful! Anyway, Im trying to work out how to get my script to define if a prduct fee is higher than an available account balance, but hitting brick walls! CODE BELOW: $Credits = 10; $Fee = 5; if ($Fee > $Credits){ //NEED MORE CREDITS }else{ //YOU CAN PURCHASE THIS ITEM } But returns that 10 is not greater than 5, i guess this is because it is only taking the first digit into consideration, even if it is 12 or 15 is still says its not higher than 5 ??? Ive been at it for hours searched google and come up with nothing... please help I may be acting thick and it may be really simple but im lost! Thanks in advance! i tried > and < but would work very well.. Code: [Select] include("connect.php"); $getbookings = mysql_query("SELECT * FROM phpbb_posts WHERE forum_id='17' ORDER BY post_subject ASC AND post_subject > $date"); just so you know.. that post subjects are dates formatted YYYY/MM/DD.. so they can be sorted. and i would like this code to select a the ones that are greater than or less than todays date.. can someone help me please? thanks Hi, i am trying to write a part of script for google shopping export, and all i want is that in this line, everything that is 0 or smaller, the line "pre-order" krijgt and everything that is 1 or greater the line "in stock" This is what i've got now, but it doesn't work I removed the rest of the long code. Code: [Select] $patterns = array(); $patterns[0] = '=<0'; $patterns[1] = '=>1'; $replacements = array(); $replacements[0] = 'vooraf bestellen'; $replacements[1] = 'op voorraad'; if(OPTIONS_TONEN_FEED_AVAILABILITY == 1) $output .= "~" . preg_replace($patterns, $replacements, $row->quantity); I wrote a code to echo "limit reached" if A is greater than B. But if A is 400030 and B is 400000 it shows no output. If A is further greater than that, let say 400060 or any number higher than that, it shows the output.. Please how do I explain that? The code snippet to demonstrate what I mean is....
<?php include_once('db.php'); error_reporting(E_ALL | E_WARNING | E_NOTICE); ini_set('display_errors', TRUE);
if (session_status() == PHP_SESSION_NONE)
{
session_start();
}
if(!isset($_SESSION['login']))
{
echo ("<script>location.href='../clogin/'</script>");
die();
}
if(isset($_POST['transfer']))
{
$username = $_SESSION['login']; $transAmount = $_POST['transAmount']; $totalTrans = $transAmount + 30; $sql = "SELECT * FROM customer WHERE username = ?";
$stmt = $connection->prepare($sql);
$stmt->bind_param('s', $username);
$stmt->execute();
$result = $stmt->get_result(); if(!$result)
{
die('ERROR:' . mysqli_error($connection));
}
$count = $result->num_rows; if($count == 1)
{
while ($row = $result->fetch_assoc())
{
$accTrans = $totalTrans + $row['dailyTrans'];
$sql2 = "UPDATE customer set dailyTrans=? WHERE username=?"; $stmt = $connection->prepare($sql2); $stmt->bind_param('is', $accTrans,$username);
$stmt->execute(); if(!$stmt)
{
die('network problem');
}
if($row['dailyTrans'] >= $row['dailyLimit'])
{
echo '<script>swal.fire("FAILED!!", "<strong>You have reached the total amount you can send per day.</strong><hr><br/><i>Visit your bank to increase transfer limit.</i>", "error"); window.setTimeout(function(){ window.location.href = "transfer1.php";} , 1700); </script>'; //exit();
}
else {
echo"";
}
}//while loop
}//count
}//submit
?>
My question Summary Again The value for $row['dailyTrans'] is 400030 and the value of $row['dailyLimit'] is 400000 This is suppose to echo out the error but fails... if $row['dailyTrans'] is greater than 400030, it echoes out. What is the logic behind that?. Please be nice with your comments as usual. Thanks . Both Value are integers!! . The code works well just that at 400030 it doesn't output that its greater than 400000
Hi guys, Probably going to be a very basic question but i'm lost, i'm trying to figure out how to display an image if the value returned is equal to or greater than a certain number, more of a hypothetical question at the moment, Thanks in advance I would like to send an email when % is >than 50%, if so get fields from Txt fiel and fields from DB and send an email to the address in the txt file.

Thank you
still shows all records in the database... any idea how i go about this? Code: [Select] $date= date('y-m-d'); $query=mysql_query("SELECT * FROM listing WHERE date >= $date") or die (mysql_error()); Is 40 characters long enough for an E-mail field? Debbie Hi all,
The output of the following line of code where user is Jack1234
$user = filter_input(INPUT_POST, 'user', FILTER_SANITIZE_STRING);using var_dump is string 'Jack1234' (length=8)I would like to know if there is someway we can use/retrieve the length value of the string that is displayed in the output or verify the string length against it. Thanks. Howdy, I have a page on my site that displays events I have uploaded. Below is the code that displays the event title. I want to know if there is a simple way to limit the characters of the title that a view will see. For example, limiting the title to 10 characters. So, if I had an event titled "My awesome new event". You would see "My awesome..." Hope this makes sense. I'm not sure if you will need to see more of the code to help me, thank you! <a href ="event-description.php?eid=<?php echo $data->EventId?>"<span class="events-title"><?php echo $data->EventTitle ?> I've got an enormous page for a pretty complex process. I just posted some changes, and it stopped functioning. Through multiple tests, I determined there was no problem with the code; it was just becomes too large at a certain point. I've read about changing settings in the php.ini file, but I'm not exactly sure what to change or what to bump it up to to allow for this huge page. Here are some current settings that I'm guessing control this problem: Code: [Select] max_execution_time = 30 ; Maximum execution time of each script, in seconds max_input_time = 60 ; Maximum amount of time each script may spend parsing request data memory_limit = 8M ; Maximum amount of memory a script may consume (8MB) ; Maximum size of POST data that PHP will accept. post_max_size = 8M ; Maximum allowed size for uploaded files. upload_max_filesize = 2M Does anyone have any insight into what to change or what settings might allow for a larger page? Not sure which one of these settings controls my problem. Thanks, as always, for any help. Hello everyone, I've searched these forums for a while now trying to resolve a problem that I have with my sessions timing out before I would like them to, but I've only gotten confused about it. I've read about changing some settings or adding code in my php.ini file but I have no idea what I'm doing when it comes to that. I'm starting the session simply by having session_start(); at the top of each of my pages. I'm including a copy of my entire php.ini file here so that you can see what I have already. Can someone please help me to figure out what I would need to do to make my sessions last at least 8 hours? Thanks in advance. Here's my php.ini file: Code: [Select] register_globals = off allow_url_fopen = off expose_php = Off max_input_time = 60 variables_order = "EGPCS" extension_dir = ./ upload_tmp_dir = /tmp precision = 12 SMTP = relay-hosting.secureserver.net url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=,fieldset=" ; Only uncomment zend optimizer lines if your application requires Zend Optimizer support ;[Zend] ;zend_optimizer.optimization_level=15 ;zend_extension_manager.optimizer=/usr/local/Zend/lib/Optimizer-3.3.3 ;zend_extension_manager.optimizer_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3 ;zend_extension=/usr/local/Zend/lib/Optimizer-3.3.3/ZendExtensionManager.so ;zend_extension_ts=/usr/local/Zend/lib/Optimizer_TS-3.3.3/ZendExtensionManager_TS.so ; -- Be very careful to not to disable a function which might be needed! ; -- Uncomment the following lines to increase the security of your PHP site. ;disable_functions = "highlight_file,ini_alter,ini_restore,openlog,passthru, ; phpinfo, exec, system, dl, fsockopen, set_time_limit, ; popen, proc_open, proc_nice,shell_exec,show_source,symlink" For PHP 7.4, what is the recommended session length that I should be using to have the best security? In DEV< in my php.ini file, session.sid_length = 26 According to the comments above that, it sounds like you can go up to 256. Is it fair to assume that larger is more secure? Also, if I set it to a larger size like 256, is tehre any risk of breaking things on my (VPS) web server running WHM/cPanel? Hey there, need some help badly. I'm trying to get the size of the BLOB data in mysql. Did a search and there are like no tutorial on this. Only relevant info was from this page, at the far bottom, it just wrote this (below code). But the writer did not explain how to use it. SELECT OCTET_LENGTH(content) FROM BloBTest WHERE filename='myimage.png' I just give it a trial an error, wrote this, but did not work. $LENGTH = mysql_query("SELECT OCTET_LENGTH(blobdata) FROM thedatabase WHERE id = 'selected_id'"); echo $LENGTH; Please help.... |
