PHP - Check If A File Is Exist In Folder
Hi everyone, I'm still learning, but getting intermediate in PHP now, but it is still challenge to learn. I'm trying to have php check to see if one file inside folder in server, seem I could not get it right, but I tested it on other site, it works, but not this script, I don't understand why it won't work...maybe logical is wrong? here my code:
if ($_POST['video']) {
$path1 = "UPLOADS/Home/";
$path2 = "UPLOADS/Breakfast/";
$path3 = "UPLOADS/Spider/";
$scan1 = scandir($path1);
$scan2 = scandir($path2);
$scan3 = scandir($path3);
$count1 = count($scan1) - 3;
$count2 = count($scan2) - 3;
$count3 = count($scan3) - 3;
if($count1 > 0) {
header('location:exist.html');
}elseif ($count2 > 0) {
header('location:exist.html');
}elseif ($count3 > 0) {
header('location:exist.html');
}
But other site, it works:
$scan = scandir($path);
$count = count($scan) - 3;
echo $count;
if($count > 1){
echo "Hello yourself!<br />";
}
Anyone will help will be appreciate! Thank you! Gary Edited April 3, 2019 by sigmahokiesSimilar TutorialsHi all - I have a form that let's a user upload an image to their specified folder. The folder is determined by the "password" the user inputs. The "password" is really just the folder name on my server, so if "michael83" was entered as a password, the directory would be "images/uploaded/michael83". That works great now, thanks to a forum user, litebearer. Thanks again. Here's my second question: I'm working on a "history" page so that a user can input their "password" and view their upload history. The form works right now. If you enter a "password" (folder name) that exists, the code will spit out the contents / files. So, now I'm looking for two things: (1) if a user enters a "password" (folder name) that exists, but there are no files in the folder, "There are no files in the $dir directory." will be echoed; and (2) if a "password" (folder name) is entered that does NOT exist, "The directory $dir does not exist." will be echoed. Here's my code so far (minus the if statements I'm looking for): $dir = $_POST['password']; $path = "images/uploaded/". $dir; $dir_handle = @opendir($path); while ($file = readdir($dir_handle)) { if($file == "." || $file == ".." ) continue; if(isset($_POST['Submit'])) $url = "http://www.mysite.com/". $path . "/" . $file; { echo "<a href=\"$url\">$url</a><br />"; }} closedir($dir_handle); As always, many thanks in advance for any help on this. Gud pm!! So i made this script to check if a username and password exist but it kinda fails me. It gives me a database connection error from my confirm_query() which means it returned false? so here's my code: Code: [Select] function check_if_exist($username, $password) { global $connection; $query = "SELECT username, hashed_password"; $query .= "FROM users "; $query .= "WHERE username = '$username' "; $query .= "AND hashed_password = '$password' "; $query .= " LIMIT 1"; $result_set = mysql_query($query, $connection); confirm_query($result_set); if(mysql_num_rows($result_set) == 1) { return true; } else { return false; } } my confirm_query(): Code: [Select] function confirm_query($result) { if(!$result) { die("Database connection failure ". mysql_error()); } } I have a another script to check if the email exist and it works perfectly, i dunno why this won't work properly.. maybe another simple mistake.. Any ideas or Violent reaction? Thanks! Hi.. So what i want to do is basicly to check if id XX exist in my database. How can this be done? Im thinking of something like: if(xx exist){do this} else{do this} Iv'e tried google etc before i posted here, but couldent really find anything where i found a soutable answer.. Hope someone can help! (: Is it possible to check if multiple rows exist at the same time. For example, if a row with the id "1" and another row with id "2" exists, and return something like true then false if only the first exists?
I have a file that provides tens of thousands to check and it takes forever. I know this sounds bad off the start, but it's not something that is run normally. Only to update my database with new additions.
Is there any good way to check a lot at once? I know you can insert many at a time and save a lot of time.
Hello, i want to check whether image exist or not, but i can't get any data about it. I have tried everything: getimagesize, file_exist, filesize, etc. <? $info = @getimagesize('http://jargames.eu/ic.php?lf=files/All phone/240x320/007-quantum_of_solace_240x320.jar'); if(isset($info['mime'])){echo 'Image exist';} else{echo 'Image doesnt exist';} ?> Ty, for your help. Hi! I wrote a small function that check if person_id already exist in the table called persons_web_tbl. If the person_id exist I get a message otherwise I add twitter/facebook profile of that person. I'm just trying to prevent duplicated entries this way. I will get person_id from table person_tbl, where are all people saved. The function actually works, I'm just curious if I'm on the right path. Thanks!
$person_id = 11;
class test extends dbh{
public function personExist($person_id) {
$sql = "SELECT person_id FROM persons_web_tbl WHERE person_id = ?";
$stmt = $this->conn->prepare($sql);
$stmt->execute([$person_id]);
$row = $stmt->fetchColumn();
if ($row > 0){
echo "found";
}else {
$person_web_twitter = "add something";
$sql = "INSERT INTO persons_web_tbl (person_web_twitter, person_id) VALUES (?, ?)";
$stmt = $this->conn->prepare($sql);
$stmt->execute([$person_web_twitter, $person_id]);
}
}
}
$person = new test ();
$person = $person->personExist($person_id);
Edited February 15, 2020 by mactron Code: [Select] $arr = array('../', 'j/', 'AcidBB/', 'fileBOMB/', 'OurHome', 'up'); foreach ($arr as $value) { // echo "Value: $value<br /><br />"; if (is_dir($value)) { echo "<tr> <td>{$value}</td> <td><font color='#66FF33'>Exists</font></td></tr><br />"; } else { echo "<tr> <td>{$value}</td> <td><font color='#FF0000'>Does Not Exist</font></td></tr><br />"; } } ~~~ Solved after posting. Sorry. ~~~ Ok i have an Array of directories i need to check before the script installs itself, I know how to check for directories but i dont know how to scan each array in the list without calling each one seperately in Code: [Select] If() { } Else If { } Else If { } And so on and so on... My Question is, If a For Statement is neaded, How would i go about checking each string in the Array List?

the problem is, the code insert data even if the phone exist why? Edited April 8 by mahendaI have a customer registration form up and running, the form allows customers to complete the forms and the data is then inserted into mysql db table via php form. I want to prevent duplicates records from already existing customers from creating a new records instead I want the customers to update their existing records in the backend. That is allow them to complete the form as normal, once they hit the submit button, the code should check if the customer first name and last name is already in the database if yes then it should update their records and if not it should insert new record to the table. I do not want to alert the customer that their records already exist. I do not know where to start. Please help Thank you so much in advance for your help. As the title says, how can i check if multiple arrays exist inside an array or not? Any help is greatly appreciated!
Hi all, I want to make a script that identifies if an image JPG file exists.

Hey guys im automatically generating a folder location to place some image files the user has uploaded into. If this folder doesnt exist how can i make it? $target_path_thumbnails = "http://www.worldwidelighthouses.com/Images/".$folderlocation."/".$foldername."/Mini/"; Thats the path style. Danny I have a script that uses simplexml_load_file to download weather xml files. It works great except when the file doesn't exist. The server returns an HTML page when the xml file isn't available but the title is something.xml. How can I check to be sure it is an xml file and handle the error when it isn't. I have tried file_exists and access the return code (it's always 200). Can I access the doctype and determine if it HTML or XML? I'm trying to do a simple image upload. It works fine on my local server but i'm moving all my files to my production server and some files i attempt to upload, via an html form, don't register. The $_FILES variable doesn't exist sometimes. I think its because of the file size but i'm not sure. The form has two inputs: "title" and "userfile". I can put something in the title and attempt to upload a small excel file and both $_POST and $_FILES exist but if i do a larger image file both $_POST and $_FILES don't even get set. I did an "echo ini_get('post_max_size');" and i get "8M". The image i'm attempting to upload is only 0.34M so i should be good there. I've replaced the actual upload script with this, which is how i found out the variables only get set sometimes Any suggestions would be much appreciated. Code: [Select] <?php echo "Upload: " . $_FILES["userfile"]["name"] . "<br />"; echo "Type: " . $_FILES["userfile"]["type"] . "<br />"; echo "Size: " . ($_FILES["userfile"]["size"] / 1024) . " Kb<br />"; echo "Stored in: " . $_FILES["userfile"]["tmp_name"]; echo "<hr><pre>"; print_r($_POST); echo "</pre><hr>"; echo "<pre>"; print_r($_FILES); echo "</pre>"; I have a page using forms to help build listing templates for eBay. I have a folder where I have hundreds of logos stored. I know the logo names but not their extensions. . . . I have to test each potential (jpg, jpeg, gif, png, etc.) until I guess right. Here is an example code for the web form:
<form action="extension_test2.php" method="post"> <p>Logo: <input name="e" value="" type="text" size="15" maxlength="30" /><p> <input name="Submit" type="Submit"/> </form> and the form's result: <? $e =$_POST['e']; if(!empty($e)) { echo '<img src="http://www.gbamedica...ebayimg/logos/'.$e.'">'; }; ?> Here is a link to the example: http://www.gbamedica...ension_test.php Use "olympus.jpg" for test. I am looking for code that can determine the file type and dynamically add the extension. Can it be done? And how can I make it so if it does already exist, it doesn't over-write information already in it? Thanks *delurk! It had to happen sooner or later!* OK, I am totally and utterly stumped. I have this script: $this->clear_cache ($this->cache_dir, $this->cache_time); if ($this->cache_time > 0) { $current_page = $_SERVER ['REQUEST_URI']; $current_page_encoded = base64_encode($current_page); $current_page_path = $this->cache_dir . $current_page_encoded; if (file_exists($current_page_path)) { // see if there is still a file with the name of the current request URI after cache cleared $content = file_get_contents ($current_page_path); return $content; } } Basically, it is for checking if there is a cached version of the page before running the rest of the script, using the REQUEST_URI as the identifier. So it calls a function to clear the cache, which works fine (and I've tried just deleting the cache files manually anyway). Then it checks if we are even caching, i.e. if cache time is greater than 0. Then it uses the BASE64-encoded REQUEST_URI (under which name the file would have been cached previously) to check if a file with that name still exists in the cache dir, and if so loads it. Now, this works perfectly with a url like: mysite/myscript/mysubpage But when the page has parameters, like: mysite/myscript/mysubpage?search=widgets the file_exists function returns TRUE, even though the directory is empty. I did do a clearstatcache(); but it made no difference and anyway, it wouldn't explain why the URI with query string would fail while the regular one would not. And even if something is wrong with my code elsewhere, the fact is it is returning TRUE for a non-existent file. Can someone prevent my slide into insanity?! i have error where my code should update existing data where id exist, it get updated ..but the others data is disappeared .only the data updated is remained $sql1 ="select*from semakan_dokumen where email='$stdEmail'";
$sqlsearch1 = mysqli_query($dbconfig,$sql1);
$resultcount1 = mysqli_num_rows($sqlsearch1);
if($resultcount1 > 0){
