PHP - Getting Rid Of Unwanted Info

Hi Everyone,

I am writing a PHP script to allow some of my site members to add links to their site. The script is setup to use a supplied link to an image, then make that image a clickable link which in turns opens that webpage.  Here is my code:

Code: [Select]
<?php
if($_POST['formsubmit'] == "Submit")
{
  $varLink = $_POST['Link'];
  $varImage = $_POST['Image'];
  $varDescription = $_POST['Description'];
}
$filea = "temp.tmp";
$fileb = "original.txt";
$filec = "newfile.txt";
$fa=fopen($filea,'w');                /* Open Temp File and Write $_POST data */
if($fa) {
   fwrite($fa,"<a href='$varLink'><img src='$varImage'></a><br>$varDescription<br><br>\n");
fclose($fa);
}
$fa=fopen($filea,'r');               /* Open Temp File and Read Contents */
if($fa) {
   $bufa=fgets($fa);
fclose($fa);
}
$fc=fopen($filec,'w');               /* Open New File to merge new and old Links */
if($fc) {
   fwrite($fc, $bufa);               /* Write Newest Link First */
}

$fb=fopen($fileb,'r');               /* Open Original file and Read it */
if($fb) {
   while(!feof($fb)) {               /* Loop through complete old file and write to new file */
     $bufb=fgets($fb);
     fwrite($fc, $bufb);
   }
}

fclose($fb);
fclose($fc);

unlink('original.txt');                  /* Delete Original File */
unlink('temp.tmp');                      /* Delete Temp File */
rename('newfile.txt', 'original.txt');   /* Rename New File to the Old Filename */

?>
NOTE The above code has been 'expanded' in my troubleshooting efforts... (i.e. I wrote the first write to file code, executed it and checked the file contents manually, then the 2nd step, etc....) so my final code will be shorter.

The problem I am having,.... when i write the 1st file 'temp.tmp', I get the expected data in the file (below).

<a href='http://www.somesite.com'><img src='http://www.somesite.com/pic.jpg'></a><br>Description of site<br><br>

However, when I read the temp.tmp and original.txt files and write it to the newfile.txt (to merge it all together) the expected data is there but with an extra entry after each 'good' entry (below):

<a href='http://www.somesite.com'><img src='http://www.somesite.com/pic.jpg'></a><br>Description of site<br><br>
<a href=''><img src=''></a><br><br><br>

I don't understand why i am getting the extra entry '<a href=''><img src=''></a><br><br><br>' in the file. Can anyone shed some light on this?

My head is sore from banging it on the wall!

I have an exercise for school that I have to work out. My teacher is letting us figure it out ourselves, but I've ran into some troubles:

- We have to make 2 files: sescook1.php and sescook2.php.
- We have to make a form for the user to fill out their name and favorite color (in sescook1.php).
- We have to check the input (whether there is input or no). If there's isn't any input, we have to echo 'Please fill out __' (in sescook1.php)
- We have to store the name in a session variable and the color in a cookievariable (in sescook1.php)
- If both fields are filled in, we ave to show a link 'go to the next page' (where 'next page' is an URL to sescook2.php).
- All info has to be shown in sescook2.php (Entered name: __, Entered color: ___)
- You have a link 'Go back to previous page' (where 'previous page' is an URL to sescook1.php)

My code:
Quote

<?php
session_start();
function checkContent() {
   if($_POST["name"] == "")
         echo "Please enter your name";
   elseif($_POST["favcolor"])
         echo "Please enter your favorite color";
   else
      echo "Go to <a href='http://localhost/webadv1011/PHPCookiesSessies/sescook2.php'>next page";
}
?>

<form name="color" method="post" action="<?php echo $_SERVER['PHP_SELF'];?>" onsubmit="<?php checkContent(); ?>">
<p>Name: <input type="text" name="naam" /></p>
<p>Favourite color: <input type="text" name="favcolor" /></p>
<p><input type="submit" name="submit" value="send" /></p>
</form>



This is the code I got so far. My problem is that the page refreshes itself after it does the checkContent function. I'm also not sure how I save my name in a session variable and the color in a cookie variable (and pass them to the next page as well!).

We haven't learned anything on cookies and sessions except our own trial and error and things I found on the internet. Unfortunately, I can't really find lots of useful info (most people refer to Ajax, but we can only use php), or I'm looking in the wrong place.

Thanks for your help in advance!

When I try to run the code below with Code: [Select]
if ( $user->uid ) it works just dandy.  But if I use Code: [Select]
if ( !$user->uid ) it puts the number one a little bit below my truncated paragraph.  It only started doing this after I put the Code: [Select]
$login = print("Log in to see full article!");.  It worked normally (besides the fact that it didn't say log in to see full article) And for description, I have 400 words of Lorem Ipsum, but you guys dont need to see that so I put elipses.
Code: [Select]
<head>
<?php
// this signifies how to truncate 
function myTruncate($string, $limit, $break=".", $pad="...")
{
  // return with no change if string is shorter than $limit
  if(strlen($string) <= $limit) return $string;

  // is $break present between $limit and the end of the string?
  if(false !== ($breakpoint = strpos($string, $break, $limit))) {
    if($breakpoint < strlen($string) - 1) {
      $string = substr($string, 0, $breakpoint) . $pad;
    }
  }

  return $string;
}
?>

<title>truncate test</title>
</head>
<body>
<?php
 $description = 'Lorem. ipsum dolor sit amet...';
// This makes it so it only applies to non logged in users
if ( !$user->uid )
{
//Replace 'XXX' with your number (Probably 500)
$description = myTruncate($description, xxx);
$login = print("Log in to see full article!");
}
 echo "<p>$description</p>";

echo "<p>$login</p>";
?>

I have 2 files; Newfault.php and thankyou.php

1) Data is entered into a form in Newfault.php
2) The data from this form is retieved in thankyou.php and is then inserted into a table called "Calls"

Problem:

My entered record is being added to my database OK, but it is also adding a blank record for some reason and I can't work out why. Can anyone help? This is for my uni assignment.

Thanks,

I'm having a problem with some php code that allows you to edit a text file. No matter what file it loads, it always adds four horizontal tabs and two spaces to the end of the text. I've attached the code to this post.

If anyone can help me with this, it would be greatly appreciated.

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?

Hey guys,

It's been awhile since I've coded in PHP and I can not for the life of me remember how to do this.

Say I have http://www.example.com/search.php?name=joe&size=small

What the PHP code to grab the ?name=joe&size=small    part?

thanks

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.

Thanks.

In my script, users login with their Username & Password. However, I'd like to be able to echo the email address used on their account. I've tried adding the email to the session
I'm not having much luck... Here's a piece of the login code(untouched);

                $username = $_POST['name'];
                $passwd = $_POST['passwd'];
                $query = "SELECT name,passwd FROM users WHERE CONCAT('0x', hex(passwd)) = '{$salt}'";
		$result = mysql_query($query);
		$login_ok = false;
		if(mysql_num_rows($result) > 0) {
		    $login_ok = true;
		}
		if($login_ok)
		{
		    $row = mysql_fetch_array($result, MYSQL_NUM);
		    $_SESSION['user'] = $row;

I've also tried messing around with this piece below in a few different ways but still nothing.

<?php echo htmlentities($_SESSION['user']['email'], ENT_QUOTES, 'UTF-8'); ?>

Any help is greatly appreciated..

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..

When I get a hit on my site I like to see where they came from and if they came from a search engine what keywords they used. So here is the refer info:

http://www.google.com/search?q=dog+training&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a

I guess I need to split everything into an array or something.

Has anyone done this?  Any Ideas?

Thank you!

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?
