Instead of exploding and getting the extension use the mime type of the images (images/gif for firefox and safari, images/pgif for IExplorer). Because if you use the method of getting extension then the users will upload any thing after changing the files extension. e.g if a file is doc.docx they will rename it as doc.gif then your code will accept it.
<?php
$typ = $_FILES['file']['type'];
if(isset($FILES['file']['name'])){
if($typ == "images/gif" || $typ == "images/png" || $typ == "images/jpeg" || $typ == "images/pgif ||$typ" == "images/ppng" || $typ == "images/pjpeg"){
$uploddir = "images/";
$uploadimages = $uploaddir.$_FILES['file']['name'];
if(move_uploaded_file($_FILES['file']['tmp_name'], $uploadimages)){
//insert data or other collected info into db.
}
}
}
?>
Using this code you don't have to worry about getting extension or lowering extension. Just use a check of file size. This code will allow user to upload .jpg, .gif, .png files.
Hey I host a website for a sports team, theres a nominations page where each member, when logged in, can cast a vote to whoever in the team they want to be captain for a tournament.
The Problem is when someone votes i store the id, name and there vote (nothing complicated), however when i want to retreive the data im using this.
if ($_SESSION['loggedin'] == true) {
$login_test = true;
$getvotes = "SELECT vote FROM `votes` where vote=1";
$collect = mysql_query($getvotes) or die (mysql_error());
$one = mysql_num_rows($collect);
$getvotes = "SELECT vote FROM `votes` where vote=2";
$collect = mysql_query($getvotes) or die (mysql_error());
$two = mysql_num_rows($collect);
$getvotes = "SELECT vote FROM `votes` where vote=3";
$collect = mysql_query($getvotes) or die (mysql_error());
$three = mysql_num_rows($collect);
$getvotes = "SELECT vote FROM `votes` where vote=4";
$collect = mysql_query($getvotes) or die (mysql_error());
$four = mysql_num_rows($collect);
}
the variable $one, $two ect.. are just the user id of the person being voted for. This works fine however, i need to add 32 more candidates. This amount of query would take forever.
Is there any way i can collect it as an array the then sort it. any help would be greatly appreciated
Thanks
try this
if ($_SESSION['loggedin'] == true) {
$login_test = true;
$getvotes = "SELECT vote FROM `votes` ORDER by vote ASC";
$collect = mysql_query($getvotes) or die (mysql_error());
$one = mysql_num_rows($collect);
I am recommending it because he is using fetch array before while loop, and then the program comes to loop and encounters the fetch array again and moves to next index in array. that's why if he is using fetch array before loop he should use do while.
Instead of while use a do while loop it will automatically fix the problem. And also remember it is a good practice to use do while when displaying data from database.
try this code void reset(int *board) and in calling reset(arrayname) in passing by raference we pass the address to the function as we do it in pointers i hope it will work. you can not pass the reference of array because it gives error if you want to pass it's address you have to use pointers because logically an array's name is also a pointer so we can pass it to functio.
Dear Rleeq! This usuallu happens due to virus which arrived almost a year ago but that's not the only reason for that it can be caused by the error in some hardware especially ram try changing your ram or try defragmenting your hard drive also make sure that if some has set a timer that automatically turns off your matchine..
