PHP - Fast_cgi Upload Size Limit

I have a simple script which records search terms and writes them to an external file. I would like to limit this file size.

The Use:
I have a search page where people can search for PDF files. I would like to have a 'cloud tag' or list of the most recent terms searched at the bottom of the page.

Here is my script which works beautifully:

<?php

$pattern = "/filetype:(\w+)/";   // filteype:(wildcard for word) to grab the file extension along with the word filetype:

if ( $_GET['q'] == "" ) {
$term = "";
} else {
       $term = preg_replace("$pattern", '', $_GET['q']); // get rid of the filetype parameter
}

$searched = $term . ", ";
$fopen = fopen("searched.html", "a");
fwrite($fopen, $searched);
fclose($fopen);
?>


The above code grabs the search term when the SERP page is opened, and writes it to a file. I will later use phpInclude to put the contents of that file on the bottom of my search engine page.

The problem is that after a million searches, this file will be huge!

Question:
How can I limit the file size and organize these search terms so that the most recent ones appear on the page?

can we limit the image by its resolutin while uploading?

i want only 130 by 110 pixel image,or i want to convert uploaded image to 130 by110 size..

can i?

lyk by using $_FILES array..?

Hi Guys

Probably a simple answer here that i'm missing.

I've got a simple upload script for an image uploader that does various checks for security sake.

One of the checks is on file size to make sure it doesn't exceed the upload limit set in php.ini . The limit is set at 2mb, so the script checks that the file doesn't exceed this limit.

The problem occurs when I try to upload a file that far exceeds the limit (the one below is 3.5mb). When i do this the upload gets passed my script because the $_FILES['picture1']['size'] gets set to no value. A print_r of the files array shows:

Code: [Select]
[picture1] => Array
        (
            [name] => DSC01468.JPG
            [type] =>
            [tmp_name] =>
            [error] => 1
            [size] => 0
        )

So what i wanted to know was whether this was normal?

And should i simply do a check to see if the size value is empty?

Any advice would be good!

Thanks Drongo

Hello!

I want to make the users in the website able only to upload, for example, 1 GB, so that when a user finishes the 1 GB available for his files, he cannot upload more files.

I know how to set up upload limit for a single file in the upload page, or even globally for anyone to upload. But I would like to know how to make each user has specific capacity, and how it is updated so that if he uploads 0.5 GB he has only 0.5 GB left.

I thought of creating a column in the `users` or something concerning upload limit that I will set it (one GB for example). If I will do that, how will I be able to determine how much he uploaded?

Any help would be appreciated.

Thank you!

Is there a way I can get the .jpg file in kilobytes from a remote url and check it to make sure it does not exceed 40 kilobytes before it saves the remote url into my database?

Hey there so I'm using the below code to upload images/files to my server via ftp. The issue I've found is that anything bigger than 200KB either stalls out and partially uploads or doesn't upload at all.

I've set my php.ini file to have upload_max_filesize = 1000M and post_max_size = 1000M. And still anything bigger than 200KB won't upload right. Any help would be appreciated. I'm using php version 5.2.14 fyi. Thanks so much.

how to put code for check file size before upload  in the if issertfile .the file is in format pdf or docs

Hi,

I'm developing a code that uploads images. I need to verify if the image have the minimum size of 100*100 pixels before the upload. How can I do this?

Best Regards,

Sorry for my bad english.

I've got a basic form for users on the site to fill out a form and upload a single image which is resized and saved to a directory on the server. I've tried the form numerous times and with images usually under 1MB the form successfully submits, data is queried and the image uploaded is resized and saved. However, recently I tried uploading larger sized images (1.2mb, 2.4mb, 3mb) and the script would seem to break. It wouldn't query any information, save any images, etc.

If you check my code attached, I have errors ready to output at all levels and not even any errors show up. When I hit submit after attempting to upload a larger file usually over 1MB, the page refreshes back to PHP_SELF as if it submitted but returns absolutely no message, alert or error and the form which was on the page is now gone.

I checked my PHP.ini file and my max file size upload is set at 32mb. Is there anything else with file size restrictions that I could be missing that is allowing this script to crash without even sending me any errors?

(1) What does this actually do? (compress it?)

$image = imagecreatefromjpeg("image.jpg");
header('Content-Type: image/jpeg');
imagejpeg($image);

By using this rather than displaying by using www.site.com/image.jpg it reduces file size of an image from 2.5mb to 0.5mb !!

(2) ImageMagick can't get these results. Am I doing something wrong? If I change the pixel size of an image in ImageMagick then I can reduce its file size, but (1) above reduces file size regardless of changing pixel size.

Hi

I am running debian lenny, apache2 php5. My fail upload fails for large file sizes. A 6.2 MB file uploads file, but a 10.2Mb file fails. I have set the Max file size to 50MB and max_execution to 600  etc in php.ini, but still have the same problems. I  have noticed many others having similar problems. Is there a solution?

Hi:

I have a site hosted (shared) on 1and1.com hosting, and they seem to have a file upload limit of 2MB.

Is there a way to overwrite this? I have been trying a .htaccess and php.ini file, but can't get it to work.

The folder with the upload form is called "admin," in the ROOT of the site.

Been trying (in both the ROOT and the "admin" folder):
php.ini
Code: [Select]
; Maximum size of POST data that PHP will accept.
post_max_size = 8M

; Maximum allowed size for uploaded files.
upload_max_filesize = 8M

ini_set('memory_limit','128M');

.htaccess (in both the ROOT and the "admin" folder):
Code: [Select]
php_value memory_limit 24M

That is all the code in each file - am I missing some code?

Can this be done?

Thank you.

}
As of now it results in every uploaded file returning the error "Max file size is 5MB."
