PHP - Question About Ajax Php Files
In my system I have a collection of php files which handle the requests from my ajax e.g. I have a function which lets users "subscribe" to another user's posts "userConnect()" and another function which lets a user uprate another user's post "uprate()"
At the moment the uprate() function uses ajax to pass it's data to a file called "ajax_uprate.php" and the userConnect() function similarly passes it's data to a file called "ajax_userConnect.php". Would I be better to combine these files into one global ajax.php file or is it better to keep them seperate? Basically I am wondering because at the moment I have a tonne of ajax_XXX files for every single function, each containing a very small amount of code. My thinking was that the smaller these files are the faster these ajax processes would take place. Am I right in thinking this or not? Similar TutorialsThis topic has been moved to Ajax Help. http://www.phpfreaks.com/forums/index.php?topic=325435.0 Hi y'all. It's been forever and a day since I've dealt with cookies, and I can't get through the cobwebs in my brain about them. I know that cookies have to be set before any output goes to the browser, but if I'm not mistaken, it's the same with sessions and sessions work in this situation. Unfortunately, the client needs cookies for integration with an existing piece of software.
Basically, what's happening is this: You load a page, click the 'login' button, which uses JQuery to change the display on the login screen from 'none' to 'block'. Use the newly-visible login form to enter username and password, which are passed via ajax to my login function. If the login is successful, I set the cookie variable and redirect the user to the protected page. However, despite the ajax reporting a successful login and redirecting the browser as expected, the check on the protected page is kicking the user back to the beginning because the cookie was never actually set.
FunctionsClass.php:
/**
* Logs in the requesting user with the agent and email values supplied via AJAX.
* @return string JSON-encoded array
*/
public function agentLogin(){
$ret['success'] = $this->_site->login($_POST['username'],$_POST['password']);
$ret['location'] = '/protected-page';
print(json_encode($ret));
die();
}
Site.php (that's $_site in FunctionsClass):
/**
* Logs in the agent.
* Checks to see if the user is already logged in, if not, attempts to do so.
* @param string $un username
* @param string $pw password
* @return boolean
*/
public function logIn($un, $pw){
if($this->isLoggedIn()){
return true;
}
return $this->logAgentIn($un,$pw);
}
/**
* Check to see if the cookie set so we know if the user has logged in.
* @return boolean
*/
public function isLoggedIn(){
// return !empty($_SESSION['mycheckvariable']);
return !empty($_COOKIE['mycheckvariable']);
}
/**
* Log the user in.
* @param string $un username
* @param string $pw password
* @return boolean
*/
private function logAgentIn($un,$pw){
// $_SESSION['mycheckvariable']['email'] = 'me@notmyemail.com';
setcookie('mycheckvariable','me@notmyrealemail.com',time()+60*60*8,'/');
return true;
}
It's not as though I'm even actually checking a database - just trying to stub this out for client presentation. And, if I uncomment the two lines using sessions and comment out the cookies, it all works perfectly. I'm not at all sure what I'm missing and would very much appreciate some other eyes on this - any takers?
I'm using WordPress, if that matters at all...
Thanks in advance!
Hello I have the following code from php websites
$myfile = fopen("/config.php", "a+") or die("Unable to open file!");
while(!feof($myfile)) {
echo fgets($myfile) . "<br>";
$txt = "Mickey Mouse\n";
fwrite($myfile, $txt);
}
inside config.php is
<?php
define('script_path', 'files');
?>
How can I replace files with another value? any help would be great thanks.
Please delete my other post as I realized it is not what I needed and I cannot delete it myself. Here is exactly what I need. I have X amount of text files (with random names) in each text file there is Y amount of lines with one word on each line. I need to open all X amount of files and take the first line from each and save it in a new txt doc. then take the second line of each and save them to a new text doc. and so on. so I have all the line 1's from all the txt files together and all the line 2's together etc. I hope that makes sense. Hello, I never dealt with such a feature before but I found a small script online that I am editing that works just fine. The problem is that it includes all of the directories in the path of my site in the zip. So if the path of my webhost is: /home/bob/files/ the zip will create a folder such as /home (inside that folder) /bob (inside that folder) /files (then the zipped files I wanted). I just want the zip files and I did store them out of the www/public_html directory to prevent people from downloading the files directly from the web but is there no way to make it not include all of those directories in the zip and only show the files? If so I will post the code that I have. Thanks i am trying to make a page to upload music to my website and add the information of the songs into a database, but i cannot get php to let me upload a file bigger than 2mb even after i went into the php.ini and changed the max_upload_size and a few others to 99mb. So i was wondering if i could put my music in a folder on my website and pull the data from the items in the folder and make database entries(probably doubtful) or if i could get some help with getting php to upload bigger files? thanks, Adam I'm a little confused with the use of absolute paths in PHP. I've always used relative paths but it's becoming an issue with some of the apps I'm working with and absolute would solve the problem. The thing is, I'm getting different results in different places and I'm a little confused. With regular HTML I seem to be able to use / as the root of my site. So if I do the following... Code: [Select] <img src="/images/name.jpg" /> That works fine no matter what page it's called from in the site and no matter what directory that page is in. I need to be able to do that same thing with PHP. Now, in my custom 404 page I have the following... Code: [Select] if($AddressURL == 'http://www.domain.com/blog/files/filename.zip') { header('HTTP/1.1 301 Moved Permanently'); header('Location: /download/filename.zip'); exit(); } That actually works just fine. If I go to the /blog/files/filename.zip (which doesn't exist) in a web browser it winds up downloading the file at www.domain.com/download/filename.zip as expected. Now where I get confused is that include files don't seem to work like that with PHP. If I do this... Code: [Select] require_once('/includes/config.php'); That winds up looking for an /includes folder all the way back at the local server root, not just the web root. so it's looking for /var/includes instead of /var/www/includes and of course that doesn't end up working. So, how come the include file paths work differently than regular HTML paths or header redirects in PHP? Is there any simple way I can always refer to the SITE root no matter what server it's running from? I've tried playing with $_SERVER['DOCUMENT_ROOT'] but it only seems to return the root of the current document, not the root of the whole site. So if I use it within a php file located in /var/www/includes/test.php it considers /includes the root which is not what I want. Any information would be greatly appreciated. Thanks! So say i have this: Code: [Select] <link rel="stylesheet" media="all" type="text/css" href="_css/styles.css" /> now the file that is linking to that is 3 directories deep, besides using a rel or absolute link, could i define the path by using something like this Code: [Select] <link rel="stylesheet" href="<?php require($_SERVER['DOCUMENT_ROOT'] . "/_css/portfolio-styles.css"); ?>" type="text/css" /> but this is actually opening the CSS in the header thanks for any explanation on how to do this This may sound like a very stupid question, but I can't find a clear answer anywhere. I'm making my first dive in OOP and all the tutorials only really show basic usage. They define a class, and show how to use it in a file. My question is how does it work to use an object throughout a program? Is it available everywhere or do I store things in sessions and start a new object on each page? For example: logging in a user. If I created an instance after confirming the credentials, would that same instance be available for use in say index.php, or would I just pass a session over and create a new instance on each page? Again, sorry if this seems dumb to some people. Right now I redirect to index page after I delete a record. However I am looking to make it so that I can delete a record without redirecting the page. I know this can be accomplised using Ajax. I have spent countless hours before trying to make it work, but it did not work.
So here is a basic setup I created. Can you please update it with ajax code so that I can see how it's done properly?
<!DOCTYPE HTML> <html lang="en"> <head> <meta charset="UTF-8"> <title>Home Page</title> </head> <body> <div class="record" > <a href="record.php?id=<?php echo $record_id ?>"><?php echo $record_name; ?></a> <div class="delete-record"> <a href="delete.php">Delete Record</a> </div> </div> </body> </html> Edited by man5, 18 August 2014 - 08:55 PM. Now I'm having this strange issue with my website I'm currently working on a tester system and I've encountered a problem that I'm unable to find the issue, tho I'm thinking my ajax php part of the script to be the thing causing it even tho it seems strange that it would cause it. The first part which is connected to where the problem occurs is the echo"<form>"; and from there, It should take you to index.php?page=tester&select=answer, now that is where it in the browser goes there tho it still shows the page stuff from the last page which is index.php?page=tester&select=applications, so it's like showing both &select=answer and &select=applications on the same page. <?php $q=$_GET["q"]; include'../config/connection.php'; $result = mysql_query("SELECT * FROM applications WHERE id = '$q'"); echo "<center><table border='1'> <tr> <th>Account Name</th> <th>Character Name</th> <th>Gender</th> <th>Skin Color</th> </tr>"; $row = mysql_fetch_array($result); echo "<tr>"; echo "<td>" . $row['name'] . "</td>"; echo "<td>" . $row['charactername'] . "</td>"; echo "<td>" . $row['gender'] . "</td>"; echo "<td>" . $row['race'] . "</td>"; echo "</tr></table></center>"; echo"<br/>"; echo"<table><tr> <th>Description</th> <th>Metagaming</th> <th>Powergaming</th></tr>"; echo"<tr>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['description']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['mg']."</textarea></td>"; echo "<td><textarea readonly='readonly' style='width:22em; height:20em;'>".$row['pg']."</textarea></td>"; echo"</tr></table><table><br/><center><h1>Answer</h1><br/><form action='index.php?page=tester&select=answer' method='post'>"; echo"<textarea name='why' style='height:10em; width:60em;'></textarea><br/>"; echo"<input type='submit' name='answer' value='Accept' /><a/>"; echo"<input type='submit' name='answer' value='Decline' /></center>"; echo"<input type='hidden' name='id' value='$q'/>"; echo"</form></table>"; ?> Now on &select=answer it included a page which the script of that include consist of the stuff below, it outputs that the query was successfully, and all that. <? if(!empty($_POST['why'])) { $why = mysql_real_escape_string($_POST['why']); $answer = trim($_POST['answer']); $id = $_POST['id']; if($answer == "Accept") { $query1 = mysql_query("UPDATE characters SET accepted = '1' WHERE id = '".$id."'"); echo"Successfully accepted"; $answer = 1; } elseif($answer == "Decline") { echo"Successfully declined"; $answer = 0; } $query = mysql_query("UPDATE applications SET answer = '$why' AND tester = '".$_COOKIE['Username']."' AND accepted = '$answer' AND answered = '1' WHERE cid = '".$id."'") or die('Could not connect: ' . mysql_error()); if($query) { echo"<br/>Query went through without problems"; header("Refresh: 5;url=index.php?page=tester"); } } ?> This is the ajax part javascript of it which gets the information for index.php?page=tester&select=applications Code: [Select] <script type="text/javascript"> function showApplication(str) { if (str==""||str==0) { document.getElementById("txtHint").innerHTML=""; return; } if (window.XMLHttpRequest) {// code for IE7+, Firefox, Chrome, Opera, Safari xmlhttp=new XMLHttpRequest(); } xmlhttp.onreadystatechange=function() { if (xmlhttp.readyState==4 && xmlhttp.status==200) { document.getElementById("txtHint").innerHTML=xmlhttp.responseText; } } xmlhttp.open("GET","tester/applications.php?q="+str,true); xmlhttp.send(); } </script>If you need any more information feel free to ask for it. Thanks in advance. So far I have managed to create an upload process which uploads a picture, updates the database on file location and then tries to upload the db a 2nd time to update the Thumbnails file location (i tried updating the thumbnails location in one go and for some reason this causes failure) But the main problem is that it doesn't upload some files Here is my upload.php
<?php
include 'dbconnect.php';
$statusMsg = '';
$Title = $conn -> real_escape_string($_POST['Title']) ;
$BodyText = $conn -> real_escape_string($_POST['ThreadBody']) ;
// File upload path
$targetDir = "upload/";
$fileName = basename($_FILES["file"]["name"]);
$targetFilePath = $targetDir . $fileName;
$fileType = pathinfo($targetFilePath,PATHINFO_EXTENSION);
$Thumbnail = "upload/Thumbnails/'$fileName'";
if(isset($_POST["submit"]) && !empty($_FILES["file"]["name"])){
// Allow certain file formats
$allowTypes = array('jpg','png','jpeg','gif','pdf', "webm", "mp4");
if(in_array($fileType, $allowTypes)){
// Upload file to server
if(move_uploaded_file($_FILES["file"]["tmp_name"], $targetFilePath)){
// Insert image file name into database
$insert = $conn->query("INSERT into Threads (Title, ThreadBody, filename) VALUES ('$Title', '$BodyText', '$fileName')");
if($insert){
$statusMsg = "The file ".$fileName. " has been uploaded successfully.";
$targetFilePathArg = escapeshellarg($targetFilePath);
$output=null;
$retval=null;
//exec("convert $targetFilePathArg -resize 300x200 ./upload/Thumbnails/'$fileName'", $output, $retval);
exec("convert $targetFilePathArg -resize 200x200 $Thumbnail", $output, $retval);
echo "REturned with status $retval and output:\n" ;
if ($retval == null) {
echo "Retval is null\n" ;
echo "Thumbnail equals $Thumbnail\n" ;
}
}else{
$statusMsg = "File upload failed, please try again.";
}
}else{
$statusMsg = "Sorry, there was an error uploading your file.";
}
}else{
$statusMsg = 'Sorry, only JPG, JPEG, PNG, GIF, mp4, webm & PDF files are allowed to upload.';
}
}else{
$statusMsg = 'Please select a file to upload.';
}
//Update SQL db by setting the thumbnail column to equal $Thumbnail
$update = $conn->query("update Threads set thumbnail = '$Thumbnail' where filename = '$fileName'");
if($update){
$statusMsg = "Updated the thumbnail to sql correctly.";
echo $statusMsg ; }
else
{ echo "\n Failed to update Thumbnail. Thumbnail equals $Thumbnail" ; }
// Display status message
echo $statusMsg;
?>
And this does work on most files however it is not working on a 9.9mb png file which is named "test.png" I tested on another 3.3 mb gif file and that failed too? For some reason it returns the following Updated the thumbnail to sql correctly.Updated the thumbnail to sql correctly. Whereas on the files it works on it returns REturned with status 0 and output: Retval is null Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif' Failed to update Thumbnail. Thumbnail equals upload/Thumbnails/'rainbow-trh-stache.gif'The file rainbow-trh-stache.gif has been uploaded successfully. Any idea on why this is? Hello I have a simple question about file handling... Is it possible to list all files in directories / subdirectories, and then read ALL files in those dirs, and put the content of their file into an array? Like this: array: [SomePath/test.php] = "All In this php file is being read by a new smart function!"; [SomePath/Weird/hello.txt = "Hello world. This is me and im just trying to get some help!";and so on, until no further files exists in that rootdir. All my attempts went totally crazy and none of them works... therefore i need to ask you for help. Do you have any ideas how to do this? If so, how can I be able to do it? Thanks in Advance, pros Hello, I've been trying this for hours now, looking at different examples and trying to change them to work for me, but with no luck... This is what I am trying to do: I have a simple form with: - 1 input field, where I can enter a number - 1 Submit Button When I enter a number into the field and click submit, I want that number to be send to the php file that is in the ajax call, then the script will take that number and run a bunch of queries and then return a new number. I want that new number to be used to call the php script via ajax again, until no number is returned, or something else is returned like the word "done" or something like that, at which point is simply makes an alert or populated a div with a message... The point is, that depending on the number entered it could take up to an hour to complete ALL the queries, so I want the script that is called to only run a fixed amount of queries at a time and then return the number it is currently at (+1), so that it can continue with the next number when it is called again. I would like to use jquery, but could also be any other way, as long as I get this to work. I already have the php script completed that needs to be called by the ajax, it returns a single number when being called. Thank you, vb I am using WPSQT plugin in my blog site .I code some files in PHP also.how to add that files in plugin files.
As the title say, I can not for the life of me get the "$bank" content to display, no matter HOW much I try... Does anyone see any errors.

So far I have not been able to find a simple example of this so if anyone can help out that would be very much appreciated. Cheers in advance. i have a select box and need to change the data with the selection.it is working correctly , my problem is that in the data i have a paging .when we going to next page no data showing . ie select box will not have any value. how to solve this problem. thanks in advance Just thought I would ask as I see that the AJAX help board is something of a ghost town (much like the MS SQL board). Since my post there doas also have some php in it, and I am in no way certain my problem is not in the php could anyone that knows a bit of both please have a look at it he http://www.phpfreaks.com/forums/index.php?topic=343419.0 cheers, just hope this circumvents the double posting rule How should I structure XMLHTTPRequests? Should I create a controller called Ajax and post/get all ajax calls through the methods of that controller? What have other people done in the past? What worked best for you? |
