PHP - Oop - What Makes This Method Not Static?
I removed the last half of the file, but what makes the login($username, $password) function not static? I want to access it statically, but I am getting an error. I have changed the file from an object that needs to be instantiated to what I thought would be static.
Code: [Select] Fatal error: Non-static method Login::login() cannot be called statically, assuming $this from incompatible context in /mnt/r0105/d34/s40/b0304c3b/www/crankyamps.com/include/uploads/pages/login.php on line 25 Line 25.

Or am I missing something?
My script has 3 classes (that are relevant to this discussion): DB, User and Validate. They are all in independent files and loaded automatically, when required, by an autoloader.

All I am trying to do is grab the USERS IP ADDRESS. Hey guys, OK, heres what I would like to do. On my form, I have 50+ variables and not all of them require a response. If inserted, they insert a blank in the DB, instead of NULL. First, does this even matter? If it does, how can I create a function that checks the var to see if its empty, and if empty $var = NULL; Thanks My issue in my php page where i need to show all the news that have the status only active. in my mysql table i have 3 fiels news,posted date and expiry date. on page load i check the status of the news and displays only the active news.For that i am doing the following code,which gives me error. that is on page load, first i select all the news ,update the status inactive for the news which has crossed expiry time i check the status of the news and displays only the active news.For that i am doing the following code,which gives me error. $query1="select time(date_posted),time(expiry_time) from muh_title where status='Active'"; $res=mysql_query($query1); $row=mysql_fetch_row($res); $expiry_time=$row[0];$dateposted=$row[1]; $query11="select addtime(time(date_posted),time(expiry_time)) from muh_title"; $res11=mysql_query($query11); $row11=mysql_fetch_row($res11); $newtime=$row11[0]; $query2="SELECT TIMEDIFF(time(date_posted) ,time(NOW())) FROM muh_title"; $res2=mysql_query($query2); $row2=mysql_fetch_row($res2); $diff=$row2[0]; //while($newtime){ $query5="select *from muh_main_title where date_posted> date_sub(now(),interval (expiry_time) hour-minute )"; //$query3="update muh_title set status='Inactive' "; $res3=mysql_query($query5); } $q="select * from muh_title where status='Active' "; $r= mysql_query($q); $row= mysql_fetch_row($r); echo "<font size='6' color='white'><b><marquee direction='left' loop='-1' align='absmiddle' behaviour='scroll' scrolldelay='90'>$row[1]</marquee></b></font>"; ?> i am sure some where i have lost the flow of code. Hi everyone. I'm completely new to PHP. I've been trying to teach myself to code with it and learn as much as I can for the past few days because it'll definitely come in handy. So far, everything I've learned is just from articles and videos.
Anyway, let's skip the boring stuff.
For literally the whole day today, I've been trying to figure out what the heck is wrong with a script I'm working with. I didn't code it myself. I'm pretty much just modifying it to fit my needs from the generic "template" it comes in.
So here's the issue:
The script is basically used to run a website with user generated content. Users can upload images and write about them. One file of the script deals with the page where the user writes and submits his/her content. Before, I had no issues. I could write a title, a few sentences, upload an image and submit it to the server. Now, seemingly out of nowhere, I'm getting problems everywhere.
Here are the issues:
1. After I fill out the form and hit submit, the page doesn't redirect to my content.
2. As soon as I hit the submit button, the page goes blank (white screen) and gets stuck on mydomain.com/submit (which is the same page where I filled out the form)
3. Along with the white screen, I'm getting the following error on top of it:
Notice: Undefined index: name in .../public_html/include/p-page-ask.php on line 126
I've spent the last 12 hours trying to fix this. For issue 3, I've read that you can use the "isset" function to fix it. But I have no idea how to code that into it. I tried different variations, but none worked to make it go away. For issue 2, I'm guessing this is a fatal php error? I have no idea what's causing it. If I view source, I just get a blank page. For issue 1, I'm guessing this has to do with issue 2 halting the page from redirecting? I'm pretty sure 2 and 3 are different errors because I've read that even if 3 occurs, the page still loads.
I've turned on all the error reporting and display functions in my php.ini file. I made sure that the server is using that particular file with phpinfo(). (Although I didn't restart my server. I have no idea how to. I'm on a shared environment). After making these changes, I still don't see any additional errors, just the notice on a blank page.
I've looked through the code for syntax errors, but couldn't find any.
I've even installed xampp and made a test environment. I read through the documentation and watched tutorials on YouTube to set it up. (I've had absolutely 0 experience with this kind of stuff). I downloaded all the exact files from my online server into my localhost environment. Funny enough, it works just fine on my machine. It doesn't even throw errors locally. However, it doesn't work online. What the heck is going on?
The only differences I can think of between the two environments are the php versions and sql database versions (xampp is newer)...but I don't know if that really makes a difference because the script USED to work on my server, so it must be compatible with the set versions.
I've been editing the files in the script for quite a while now. I know when I first started, the uploads would work just fine. Then I didn't upload for a while because I already tested it out and knew it worked, so I just continued working on the script. I may have modified something that's now causing the errors. But then wouldn't that cause the localhost environment to fail too? If the files are exactly the same, how could one fail to work? That makes no sense at all. I'm looking at this code lost and hopeless. I'm getting sad.
If ANYONE has any suggestions on fixing this, PLEASE let me know. I don't know what to do anymore.
If you need me to upload any of the other files, just ask.
Here are the error logs from the server:

What for static in this case? I am using php5.2.x. Please give some light on using static in php? class One{ function disp(){ echo " disp here"; } static function show() { echo "show here"; } } One::disp(); One::show(); I write for example class Text: class Text { public static function test() { return 'test text'; } } Today I found this code: class Text { /** * Protected constructor since this is a static class. * * @access protected */ protected function __construct(){ // Nothing here } public static function test() { return 'test text'; } } How much appropriate is to write this? /** * Protected constructor since this is a static class. * * @access protected */ protected function __construct(){ // Nothing here } Is it possible to have a static variable in php? I want the value of a variable to remain unchanged the next time a function is called.
hey guys i have a static attribute $_exception_handler which is set to Exception and....now this value could change to a customer exception_handler but what i want to do is <?php catch (self::$_exception_handler $e) { } but im getting an error...is there a way of doing this...any help would be greatful thanks class below <?php class Autoloader { protected static $_exception_handler = Exception; protected static $_classes = array(); public static function load_library($class_name) { $file = ROOT . DS. LIBRARY_DIRECTORY . DS . $class_name . CLASS_EXTENSION; try { self::load_class($class_name, $file); } catch (self::$_exception_handler $e) { echo $e->getMessage(); } } public static function load_exception($class_name) { } public static function load_class($class_name, $file) { if (!class_exists($class_name, FALSE)) { if (file_exists($file)) { require_once $file; } else { throw new Exception(sprintf('Class %s not found.', $class_name)); } } } } I have the following static method: public static function query($query){ self::$num_queries++; return mysql_query($query)or die(mysql_error()); } I then call it like this: $oql = Mysql::query("SELECT first FROM members WHERE member_id = '{$this->owner}'"); $rql = mysql_fetch_assoc($oql); I then get the following error: Quote Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /incl/php/classes/Photo.php on line 13 Why am I getting this error? I'm looking for some advice on the best way to achieve the following... I'd like to change the way URLs are shown for our search results pages. The website is a holiday rental website and currently the URLs look like this: domain.co.uk/search?region=[value]&type=[value]&budget_low=[value]&budget_high=[value]&name=[value]&size=[value] Ultimately I'd like them to look more like this: domain.co.uk/region-value/type-value/budget_low-value/budget_high-value/name-value/size-value. Any advice would be greatly appreciated. Is it ok to do this? Code: [Select] class Two { function anything() { classOne::anyMethod(); } } I'm sure it is but this doesn't pose very well for if I wanted to swop out one class for another. I'd then have to make changes to the code (unless I were sure all classes were named the same). -- What I want it for (and this may be another issue), is this: I may need to create more than one database instance: Code: [Select] //Database exends mysqli $db[1] = new Database(2);//database 2 used this time $db[2] = new Database(5);//db5 I then always use Database::closeAll() at any point in my script to ensure all connections are closed. Of course $this->close wouldn't close all instances/connections, just the one I was working on. I know I don;t have to close all connections, but I may as well, and there are other occasions where the first part of this question applies, so please don't just respond "no need to close". Database::closeAll() is this: Code: [Select] public static function closeAll() { //closes ALL active instances (not just this one) global $db; foreach($db as $v) { $db[$v]->close(); unset($db[$v]); } } heres an example of the code i have Code: [Select] class someclass { public function run($parm) { system($parm); } public static function create($item1,$item2) { $this->run($item1 . $item2); } } then i have a file that attempts to use the create method: someclass::create($one,$two); when interpreting, i get this error: "Using $this when not in object context in" does anyone know how I can fix this? I think I understand why its wrong (the class hasn't really been set up) - I just dont know how to correct it. Is there a way I can access class functions without using $this ? additionally I tried making the run method static too, but that didnt seem to work. |
