PHP - Change Frontpage Info

Very simple question. I have a table with courses and a table with students registered for those courses. I have a page where I can change the course name. What I want to do is, when changing the course name in the course table, I want all students in the students table who are already registered for that course to have that course name updated as well in the student table.

 I'm currently using a field cid to update the courses in the course table however, the student table doesn't have a cid field rather a cname ( course name) which I want to use to update the fields in the student table.

 Is it possible to use
Code: [Select]
<a href=\"editcourse.php?cid=" for more than one field of info? i.e transfer the cid + cname and so you can use $_GET[cid]"; and $_GET[cname]"; ?

Something like this maybe ( dont know how the code will go) "editcourse.php?cid=&cname=" ?

Do I have the right idea for how to go about this?

Hi Ive currently developed a script that connects via an API to send a message, and tested it with one user and it works perfectly. But now im bit stuck to send it to multiple users. All my visitors unique IDs are being stored into a file called unique.csv all in 1 column under each other. But what im currently trying to do is to recall the info from the csv and make a contact list to broadcast the message to.   The csv file looks like:     27823116700 m59317461002

Anyone see why its not sending the money?

Thanks.

let's say I have 100,000 users on my forum

i want to cache there PROFILE INFO (About me) in .php files

which is easy/etc but would that be more space than 100k rows in a db table, or 100k .php files?

just wondering,

prob a stupid question but

atm I cache some lottery info and some other stuff, but that's only 1 .php

it would be dumb to cache info and have 100k .php's for each user ID right?

or maybe story it all in 1 .php? would be a HUGE Filesize? rather just keep the data in MYSQL right?

<?php  include(thedatabase.php');

Hello Guys...
I'm new to php & mySQL... I need help... Need something to know... please help me...
I'm using ubuntu 11.10, Aptana Studio 3, xampp 1.7.7.
Also i'm using windows 7, notepad++ & wamp.
When I visit "localhost" on my firefox. I saw a xampp or wamp welcome page. The name of the file is "index.php".

1. I need to know can I delete this file ? Bcoz i'm working on another file but it's the same file name.

2. When I upload my site on host like hostgator. How do i edit my live site? And preview it.

3. How do i store my post on database ? Like fb status update, blogger post or forum post

I wanna write a site that i can post something without using html <p></p>. The main problem when i need to post something then everytime I need to edit the source code. Example:<p>some text here</p>.

I don't wanna edit source everytime.

Another Ques: Is Aptana Studio and notepad++ enough to write a site or I need another tool ?

Any book suggestion ?

please guys help me i'm new to php & mySQL..

For some odd reason, my MySQL array is not returning any data. I echo'd the query and it is correct, I looked at the database and that row is in there, but when I print_r the array, nothing. Here is the code.

$infoquery = "SELECT * FROM '$endotype' WHERE ID = '$typeid' ORDER BY ID DESC LIMIT 1";
$info = mysql_query($infoquery);
echo $infoquery;
$infoout = mysql_fetch_array($info);
print_r($infoout); Its a very simple query and its driving me nuts.

Hi guys

I need some info
Am doing an upload page for pictures, that crops images to two different sizes which works fine with small images. However some larger images it doesn't work (locally it works but not on the my server provider). I can upload the file (3481 * 2346 at 300 dpi) no problem but it actually never executes the imagecreatefromjpeg($myUploadedFile). Is there any issues with large file. I've been doing some recherches but can't seem to find any answer. The obvious idea is to have people upload photos without asking them to resize them.

Thanks

This is a multiplication test for students to take and when they finish they click the score button. after they click the score button it tells them what their score is, with the opportunity to take it again.

What I am trying to do is make this able to keep the recent score and just post the next score. Right now my app just gives the first score and then when I take the test again it just refreshes and gives the new score. I want it to play the new score under the old score. I can't seem to figure out how to do this. If someone could help point me in the right direction. Would appreciate the help.


Here is my code for my app....



Code: [Select]

require_once('database.php');

$correct = 0;


//print_r ($_POST);
$time1 = $_POST['ts'];

$now = new DateTime();
$time_span = $now->diff($time1_object);

$minutes = $time_span->format('%i');
$seconds = $time_span->format('%s');
$seconds+= $minutes * 60;

echo "It took $seconds seconds to complete the test<hr />";



foreach ($_POST as $problem => $answer)
{
if ($problem <> "btn_score" && $problem <> "ts" && $problem <> "result_name")
{
//echo "$problem -- $answer <br />";
$problem = explode('_', $problem);
$num1 = $problem[2];

$right = $num1 * $num2;
